1. Proxysmart manual [v2].

1.1. The goal of the software.

The software allows running your own 4g proxy farm. It runs on a Linux box (PC) with USB hub and the modems.

Functions:

  • IP resets on modems (+ automatic rotation + checking IP uniqueness)
  • WebApp for checking statuses of the modems, for creating users and ports, IP rotations
  • WEB API for all actions
  • Bandwidth quotas and Speed limits per proxy
  • Exposing proxy ports, so they are available from world wide
  • Reading,sending SMS and USSD codes
  • OS spoofing, to simulate OS TCP fingerprints of: MacOS, iOS, Windows,  Android (+any other OS)
  • Proxy ACLs (what to allow/deny to proxy users) - blacklists
  • Creating mobile VPN together with proxies
  • Socks5 supports UDP and QUIC (HTTP/3.0)
  • No leaks
  • Native DNS from mobile carriers
  • Large set of supported USB modems, LAN routers, LTE modules, Android phones.

Concept:

  • A Modem is a device that connects to a mobile carrier
  • A Port is a proxy (SOCKS5 + HTTP) + Openvpn profile, built on a modem
  • Create multiple Ports on a Modem
  • Each Port has its own settings

1.2. Architecture

  • Onsite: box with Ubuntu, USB hub and modems
  • Remote: VPS with proxy ports (optional)

Online services are used:

  • IP checker - http://ip.tanatos.org/ip.php which is simple PHP script that returns visitor’s IP. It is used to detect whether a modem is really online. Can be replaced with one of https://ifconfig.co or similar, but I was not happy with their reliabiality, they are down sometimes. It is set in WebApp→Global_settings
  • URL that is latency on modems measured with. Defined as COLLECTD_PINGER_HOSTNAME , default is t.co

1.3. Configuration.

Variables are set in the WebApp→Global_settings and in /etc/proxysmart/conf.txt.

Each variable has brief description in place.

1.4. Mongodb integration

Mongodb Schema

Mongodb contains 2 collections: modems and ports.

  • modems collection.

It contains real modems, array of associative arrays, take allowed fields in store_modem API call.

  • ports collection

It contains proxy ports given to the users. Each port is connected to a modem by the IMEI key. So you can attach 1 or more ports to a modem. It is array of associative arrays, take allowed fields in store_port API call.

MongoDB Configuration

MongoDB URI is defined in /etc/proxysmart/conf.txt :

  • MONGODB_URI="mongodb://proxysmart2:[email protected]:27017/proxysmart?readPreference=primary&ssl=false"

If you want to use other Mongodb collection names instead of modems and ports , define them in /etc/proxysmart/conf.txt :

  • MONGODB_MODEMS_COLLECTION=modemsNEW
  • MONGODB_PORTS_COLLECTION=portsNEW

after changes:

  • systemctl restart proxysmart
  • proxysmart.sh reset_complete

Moving Mongodb to other server

Sometimes you want to move Mongodb to a cloud server.

  • update MONGODB_URI to new Mongodb URI in /etc/proxysmart/conf.txt
  • if your new mongodb URI has +srv extension , install a PIP module: /var/www/proxysmart/venv/bin/pip install "pymongo[srv]"
  • install apt install python3-dnspython
  • systemctl restart proxysmart
  • proxysmart.sh reset_complete

2. Installation

2.1. Initial installation

Supported OS and Architectures:

Armhf (arm 32 bit) doesn’t have Mongodb support!

Install a fresh OS.

Unplug any USB modems. 

curl https://proxysmart.org/install-v2 | bash

Reboot or run proxysmart.sh reset_complete.

After that either enjoy the Demo version at http://localhost:8080 or check License section.

**Rockpi Notes**

2.2. Adding modems

  • Read the section Adding modems of this manual.
  • Plug in all modems you have,
  • Navigate to the WebApp ( http://localhost:8080 or http://your_box_lan_IP_address:8080/ , proxy / proxy )
  • Wait ~20 sec to let them initialize.
  • For each modem, click “Add modem”, assign a Nickname.
  • For each modem, create proxy ports instead of “random” ports.
  • Reboot and wait 1 minute
  • Navigate to the WebApp and make sure the WebApp shows the modems.

2.3. Forwarding proxies ports

Why? In order to make proxy ports available for all users around the world.

Basic info on forwarding ports

You have 2 methods of forwarding ports :

  • either forward them through a VPS
  • or forward them through your own LAN router.

Which to choose?

If these conditions are met:

  • you have static fiber IP at 4g proxy farm location,
  • and ISP allows incoming connections to that static IP
  • and Upload and Download of fiber Internet is at least 40 Mbps.
  • you don't need UDP in Socks5

.. then choose port forwarding through your LAN router. Otherwise, choose port forwarding through a VPS.

2.4. Forwarding proxies ports through a VPS.

The VPS server can be a cheap 1GB DigitalOcean / Linode / Vultr VPS or similar.

It has to be located as close as possible to the 4g farm server ( for lowest ping ).

On Proxysmart multi modem server

Go to the WebApp , copy content of the SSH public key from the bottom of the page. We will refer to it as PUBKEY below.

Also it is stored on disk as /root/.ssh/fwd.pub

On VPS

Check if your VPS has no firewall. Disable it if it has – Both inside Linux OS and in hoster panel.

Install & run Ansible. 

apt update && apt install git ansible -y
cd ~/
git clone https://github.com/ezbik/proxysmart-vps.git
cd proxysmart-vps

If running Proxysmart v2.3+ : 

git checkout v2.3

edit the file vars.txt 

nano vars.txt

Replace PUBKEY with the PUBKEY . Save the file by pressing Control O and exit the editor by pressing Control x .

Run Ansible: 

ansible-playbook proxysmart-vps.yml

done.

On Proxysmart multi modem server

in WebApp→Global_Settings:

  • set VPS variable to the VPS IP.
  • set PROXY_PORTS_FORWARDER_ENABLE On.
  • Pick a port for SSH_REMOTE_PORT, in most cases 6001 is fine. The port (TCP) has to be free on the VPS
  • Pick a port for WEB_REMOTE_PORT, in most cases 7001 is fine. The port (TCP) has to be free on the VPS
  • Pick a port for OPENVPN_SERVER_PORT, in most cases 1501 is fine. The port (TCP+UDP) has to be free on the VPS.
  • set VPS_SOCKS5_SERVER to scheme with authentication on VPS e.g. socks5://px:[email protected]:2323 where 3.3.3.3 is a VPS IP.
  • Click SAVE

Run proxysmart.sh reset_complete

On VPS

issue the command ss -tnlp and you will see proxy ports are bound with sshd daemon. That means the ports are forwarded.

On your private desktop or any other PC
  • visit http://vps_ip:7001 for the WebApp
  • you can ssh to VPS IP and port 6001, and that goes to the multi-modem-server:22.

Cloud VPS IP change

If Cloud VPS IP is changed, update it on multi-modem-server side by defining new VPS variable in WebApp→Global_settings and rerun proxysmart.sh reset_complete there (or reboot).

2.5. Forwarding ports through your own LAN router.

Steps

Consult with documentation of your LAN router. Forward these ports from ISP IP address to the LAN IP of proxysmart server:

  • TCP 8001-8999 for HTTP proxies
  • TCP 5001-5999 for SOCKS5 pproxies
  • TCP 8080 for the WebApp , will be used in 'REWRITE_WEBAPP_TO'
  • TCP 1194 for Openvpn (if it is working in TCP mode) , will be used for OPENVPN_SERVER_PORT
  • UDP 1194 for Openvpn (if it is working in UDP mode) , will be used for OPENVPN_SERVER_PORT

Notes

  • Set in WebApp→GlobalSettings :
  • PROXY_PORTS_FORWARDER_ENABLE : Off
  • REWRITE_WEBAPP_URL : On
  • REWRITE_WEBAPP_TO : http://myrouter.com:8080
  • REWRITE_HOST_IN_PROXY_CREDS : On
  • REWRITE_HOST_IN_PROXY_CREDS_TO : myrouter.com
  • OPENVPN_SERVER_HOST : myrouter.com
  • OPENVPN_SERVER_PORT : 1194

Replace myrouter.com with your actual external Hostname or external IP addresss.

  • click SAVE.

Then finally reconfigure the system by running proxysmart.sh reset_complete .

2.6. Upgrade

2.6.1. Upgrade from older V2

NOTE when dpkg will ask whether to replace old config file with new one, answer N (No) or just press Enter. So old config file is saved.

Run these commands: 

curl https://proxysmart.org/install-v2 | bash

Reboot or run proxysmart.sh reset_complete.

Notes on upgrade to v2.3

Default values changed:

  • QUIC_SUPPORT : old default value Off new default value On
  • PROXY_PORTS_FORWARDER_SOFTWARE : old default value ssh new default value ssh+haproxy

2.6.2. Upgrade from V1

Show

2.7. Development version installation

Why? To unlock new features that are not yet in the Main version.

v2.3 

curl https://proxysmart.org/install-v2.3 | bash

Reboot or run proxysmart.sh reset_complete.

2.8. Older version installation

v2.1 

curl https://proxysmart.org/install-v2.1 | bash

Reboot or run proxysmart.sh reset_complete.

3. Adding modems

Proxy credentials for new modems

When adding new modems, please use

  • unique HTTP ports from 8001 to 8999,
  • unique SOCKS ports from 5001 to 5999.
  • unique nicknames like dongleXXX or whatever else. Don’t use nicknames like randomXXX, that are assigned automatically.

3.1 Adding a new modem (USB)

  • Remove PIN from the modem’s SIM card and plug in the modem into USB port or USB hub.
  • Check whether your modem Web App (e.g. Huawei’s E8372 / E5xxx or ZTE MF79 or Alcatel MW4x ) requires authentication, and if it does, set its admin password to admin123. Basically to the value of DEFAULT_HILINK_ADMIN_PASSWORD variable in WebApp→GlobalSettings . Otherwise many functions will not work, and its IMEI will be detected similarly to 2-1.1.2
  • Plug in the modem.
  • Wait ~5 minutes
  • The modem will appear in the WebApp.
  • Click ADD MODEM on it, assign a unique Nickname, click APPLY.
  • Create Ports on the modem - click ADD PORT against the modem, assign a unique Port name, HTTP & SOCKS5 ports, Login and Password, then click APPLY.
  • Refresh the WebApp, done!

3.2. Adding a LAN modem.

Configure the server with 2 LAN cards

Assume you have 2 LAN cards, e.g. enp6s0 main LAN, enp2s0 is dedicated for LAN modems:

nmcli con 

NAME                UUID                                  TYPE      DEVICE 
Wired connection 1  bbbee134-51c3-3830-801f-9636470e0708  ethernet  enp6s0
Wired connection 2  000ed912-2d99-3f37-882b-d79ad13102e7  ethernet  enp2s0
  • Rename Wired connection 2 → HUBS
nmcli con modify Wired\ connection\ 2 con-name HUBS
  • Disable DHCP and IPV6 on HUBS and assign static IPv4 address
nmcli con modify HUBS ipv4.method manual ipv4.addresses 192.168.10.100/24 ipv6.method link-local ipv4.route-metric 300

So you will add the LAN modems to 192.168.10.0/24 network as 192.168.10.1, 192.168.10.2 etc. 

systemctl restart NetworkManager

Delete old route: 

ip ro del default via 192.168.10.1

Confirm you have only 1 default route via main LAN, query with 

ip ro

Output: 

default via 192.168.1.1 dev enp6s0 proto static metric 100

Add the modem

  • Change the modem’s web admin password to something stored in WebApp→GlobalSettings as DEFAULT_HILINK_ADMIN_PASSWORD variable.
  • Change the modem’s IP to something unique e.g. 192.168.10.10
  • Put the modem's LAN outlet into Ethernet switch together with the Proxysmart server.
  • On the Proxysmart server make sure you can ping the new modem by its IP you set in previous step.
  • Make sure LAN_MODEMS_ENABLE is enabled in WebApp→GlobalSettings.
  • Add Lan modem in the Webapp→Edit_modems , scroll to the bottom, and add as lanmodem10 , 192.168.10.10 .

Then either wait 5 minutes or run the command sudo proxysmart reset_gently, it will find new modems. Then , refresh the proxysmart Web App and assign proxy logins and passwords to the new modems.

3.3. Adding an Android phone

Main guide dedicated to adding Android Phones: Android phones guide

3.4. Adding a virtual modem (backend proxy).

A virtual modem is a in fact a redirect to a 3rd party proxy (HTTP or SOCKS5) so you can build own proxies based on that and resell them.

They even can be rotated if the backend proxy supports it.

How to add?

Make sure BACKEND_PROXIES_ENABLE is enabled in WebApp→Global_settings .

Add them the Webapp→Edit_modems→Virtual modems

, scroll to the bottom, and add each with the following fields

  1. id has to be in the form 'bproxy' + a number e.g. bproxy1 or bproxy2
  2. creds is a line with credentials of the backend proxy e.g. http://Mylogin:Mypassword@Server:3128 or socks5://Mylogin:Mypassword@Server:1080
  3. ip_reset is an optional parameter , the URL for triggering IP rotation of the backend proxy

Click SAVE

Then either wait 5 minutes or run the command sudo proxysmart reset_gently, it will find new modems. Then , refresh the proxysmart Web App and assign proxy logins and passwords to the new modems.

4. WEB API

1. Web API description.

WEB API endpoint is the URL that Proxysmart WebApp available at.

It can be

  • LAN_IP:8080 when you call it from the same LAN
  • VPS_IP:7001 when you forwardded ports to the Cloud VPS
  • STATIC_IP:8080 when you forwarded ports via your LAN router and your ISP gave you STATIC_IP

Also attach proper username:password (the -u parameter).

Whenever below you are seeing localhost:8080, replace it with the actual WEB API endpoint.

1.1. Workflow

quick start:

  • Populate modems collection with modems objects
  • Populate ports collection with proxy ports objects
  • for each added modem call 'Apply settings for a modem' WEB API call. It will configure each modem and its ports

Detailed start

Assume you have given a fresh Proxysmart server with multiple modems, by default each of the modems has generated a random modem nickname and random ports on it.

IMEI is a unique identifier for a modem.

So, query full status with /apix/show_status_json, gather IMEI's where nicknames are like random, for each of these IMEI do:

  • generate a unique modem nickname, e.g. “dongle_100” and store modem object with /crud/store_modem
  • generate proxy ports for the modem, create proxy port objects and store them with /crud/store_port
  • apply the settings for the modem and for its ports with /modem/settings

(done)

if you edited a modem

call 'Apply settings for a modem' WEB API call for the modem.

if you edited a port

call 'Apply settings for a port' WEB API call for the port (faster)

or

call 'Apply settings for a modem' WEB API call for the modem. (slower, affects all modem's ports)

if you deleted a port

call 'Purge port' WEB API call for the port (faster)

or

call 'Apply settings for a modem' WEB API call for the modem. (slower, affects all modem's ports))

7. License

1. Demo license

Installation is shipped with default demo license.

It allows you to run proxy on 1 modem.

In order to run more modems, buy a License.

2. Requesting a License

2.1. Get the machine data

Method1. From the WebApp:

  • Open the proxysmart WebApp at http://localhost:8080 or http://LAN_IP:8080
  • Scroll down to the Machine Data text.
  • Copy MachineData value to the Clipboard.

Method2. From the CLI:

  • Open terminal
  • Run sudo proxysmart.sh license_status
  • Copy machine_data value

2.2. Contact Sales Team

Send the copied value to proxysmart.org

2. License installation

You will be given the license and license signature. Both are sequences of numbers and characters. Then submit both either via WebApp or CLI:

submitting via WebApp

Open the WebApp , http://localhost:8080 , expand License section and type in the keys & submit both.

submitting via CLI

run commands 

proxysmart.sh submit_license LICENSE
proxysmart.sh submit_license_signature LICENSE_SIGNATURE

3. Restoring Demo license.

If your paid license expired or broken, restore DEMO license

Method1. From the WebApp:

  • Open the Proxysmart WebApp at http://localhost:8080 or http://LAN_IP:8080
  • click Restore Demo License.

Method2. From the console:

run sudo cp -v /usr/share/doc/proxysmart/examples/license.txt* /etc/proxysmart/

4. Upgrading license

The idea:

  • When adding modems, you only pay of the remaining time of the license
  • When approaching license end, upgrade price is lower

The case:

  • You bought a license for 50 modems / 1 year : USD 416
  • 8 months past, 4 months remained
  • You want to add +20 modems
  • New price of 70 modems / 1 year : USD 550.4
  • Time factor: 4 month / 12 month = .33
  • Difference between old price and new price : USD 134.400
  • The difference with applied Time factor: USD 134.400 * 0.3333333333
  • total to be paid: USD 44.8

Or simple formula:

( New_price - Old_price ) * ( Tr / T )

where:

  • Tr - remaining number months to the end of license
  • T - number of months of the original licence

8. FAQ and Troubleshooting.

1. Where is WebApp

One of

  • http://localhost:8080/
  • http://LAN_IP:8080/
  • http://VPS_IP:7001/

By default login/password are proxy / proxy.

2. How to use proxies

  • If proxy ports are forwarded via remote cloud VPS: then the proxies can be used from all over the Internet, by that VPS IP and proxy port numbers.
  • From the same LAN where multimodem server is located: by the server’s LAN IP and proxy port numbers.

3. Speedtest for the clients

Why? In order to test quality of connnection between proxy/VPN users and the server, not involving mobile equipment.

How?

For the proxy users:

Open the URL in the browser: The WebApp plus /openspeedtest/ e.g. http://VPS_IP:7001/openspeedtest/ , login/password are speedtest / pw2000pw

For the VPN users:

While connnected over the VPN, open the URL in the browser: http://172.22.27.1/openspeedtest/ , login/password are speedtest / pw2000pw

4. Reconfigure all modems & proxies.

Method1. Click the button “Reset Complete” on the main screen of the WebApp in the bottom.

Method2. In linux console, run: proxysmart.sh reset_complete

Also it is done after reboot automatically by a Cron job.

5. How to change proxy credentials for a modem. How to rename a modem.

  • click EDIT on a modem or a port, set new values
  • click APPLY

6. Reset (change) IP on a modem.

The options are below.

  • From Web App

Click Reset Ip button.

  • From command line.

Run: proxysmart.sh reset_quick_nick dongle1

Where dongle1 is a Dongle “nickname” that is seen from output of proxysmart.sh show_status

  • From Web API.

check WEB API section of this manual.

How to rotate a modem periodically?

  • WebApp method

Update modem’s settings in the WebApp and click APPLY.

  • Cron method

Install a Cron job. Edit a file /etc/cron.d/proxysmart, add a line ( or uncomment a commented line.. )

*/10 * * * * root run-one /usr/local/bin/proxysmart.sh reset_quick_nick dongle3

so that a modem with the Nickname dongle3 is rotated every 10 min.

Repeat for each modem you want to rotate periodically.

7. How many modems can I run on a single computer?

Hi , technically it depends on how powerful this PC is, and how intensively proxies are used.

  • Raspberry PI - 4 proxies (roughly)
  • a miniPC (Intel NUC or similar) - up to 10
  • a Laptop like Core i5 - up to 30.

Also it depends on what Plan you buy.

Also it depends on USB configuration, for maximum number of modems:

  • disable USB3.0 in BIOS
  • use USB2.0 hubs

8. How to set TTL and why?

In some cases custom TTL must be set in order to have Cell Operator think we are not using the modem in hotspot  tethering mode. I.e. we don’t share its data. By default Linux OS has ttl = 64. To change Cell Operator perception of the situation, we want to set it +1 i.e. 65.

Edit WebApp→GlobalSettings and set CUSTOM_TTL_SET and CUSTOM_TTL_VALUE=65 and regenerate settings.

9. How to set MTU and why?

In some cases different MTU values connect with different types of ISP’s. You may want to change it.

Mtu can be only lowered. E.g. if you have MTU 1390, you can set 1340. Not opposite.

- WebApp → GlobalSettings → enable CUSTOM_MTU_SET . - Set MTU in the WebApp for each modem.

10. How to set extra settings for a proxy port.

Those are optional and are set in the WebApp

  • WHITELIST - allowed customers IP’s who are not required to type in proxy password (IP-based auth).
  • bandwidth (speed) limit. Values are in mbps (megabits per second).
  • DENIED_SITES_ENABLE (on/off) and DENIED_SITES_LIST (list of blocked sites patterns).
  • Bandwidth Quota (Megabytes) and Bandwidth Quota Type (daily/monthly/lifetime)

11. How can I access the web interface admin panel of each modem?

Proxysmart 2.2+ :

  • Open WebApp. Locate the modem. Click its IMEI to open its individual page
  • Click Browse Modem

12. How to set monthly traffic quota per modem?

In the WebApp, set monthly traffic quota. Click EDIT & APPLY.

13. How to make my proxes Open (i.e. not requiring authentication )

Set OPEN_PROXIES in WebApp→GlobalSettings and regenerate all configs.

Note, when proxy ports are forrwarded via a VPS, the proxies are available to any internet user. Use it with caution.

14. Get monthly/daily proxy usage.

Click Bandwitdh Stats in the WebApp, or use “Report Bandwidth” CLI or WEB API call.

15. How to get current number of connections for a modem?

Run a command

ss -o state established | grep -c :8038

But change 8038 with HTTP port of a desired proxy

16. How to read SMS from a modem.

You have these options.

  • Click Read SMS in the WebApp
  • run proxysmart.sh list_sms_for_a_modem_by_imei_json 999999999999999 i.e. IMEI of required modem.
  • Browse to the modem IP ( it is shown as GW in proxysmart.sh show_status ) through the proxy. Click SMS button.

17. How to change WebApp password

By default it is set to proxy / proxy.

In the WebApp→GlobalSettings scroll to the bottom, set new WebApp password. NOTE: login remains proxy.

Command line method. 

sudo htpasswd -b /etc/nginx/htpasswd proxy NewAweSomePassword999999

If you want to change username as well, just delete the file and then assign new password 

sudo rm /etc/nginx/htpasswd
sudo htpasswd -b -c /etc/nginx/htpasswd MyNewUsername NewAweSomePassword999999

18. OS Spoofing

Os Spoofing is used to simulate other OS TCP fingerprints.

What OS can I spoof?

MacOSX, iOS,  Windows,  Android.

How to enable OS Spoofing?

In the WebApp set the needed OS per each proxy port (click EDIT PORT).

How to test OS Spoofing ?

Visit one of these websites (IP checkers) through a proxy. Find something like “OS TCP fingerprints”.

  • http://witch.valdikss.org.ru/
  • https://thesafety.us/
  • https://whoer.net → extended results
  • https://browserleaks.com/ip

Can I dump OS TCP fingerprint from a real device and use it?

Yes, contact me.

I enabled OS TCP spoofing, but it is not working!

The reason may be that the operator passes all traffic through its internal proxy, or in other way modifies TCP signatures. Then local OS TCP modifications are overwritten. Is it bad? No! Because still traffic looks natural as it was coming from this operator network.

Try other operator.

19. Performance tuning

When >50 modems are added, play with MAX_PARALLEL_WORKERS_STATUS variable, on faster CPU’s it can be set to 8 or 16 (to the number of CPU cores). It can be set by editing the file /etc/proxysmart/conf.txt. It affects number of threads

  • when generating status of the modems
  • when generating configuration of newly added modems

20. How to lock network mode per modem

Set TARGET_MODE the modem's settings in the Proxysmart WebApp. Allowed values:

  • auto
  • 3g
  • 4g

21. What if a modem connected via 3G or 2G, and I want 4G?

Lock network mode to 4G and rotate its IP.

22. I want to add extra users on a modem

In the WebApp, create more ports on the modem, each port means a dedicated proxy.

23. Is IPV6 supported?

Yes but it’s off by default.

On modems , edit APN and set APN type for both IPv4 and IPv6 , e.g. Ip4Ip6 or Ip4+ip6, there is a dropdown list for that.

On Proxysmart box: Update WebApp→GlobalSettings → IPV6_SUPPORT On

and reset configuration proxysmart.sh reset_complete ; or even better do a reboot.

24. Nagios integration.

There is a plugin embedded, run it as root,

/usr/lib/nagios/plugins/proxysmart-nagios-helper.sh IMEI

or

/usr/lib/nagios/plugins/proxysmart-nagios-helper.sh NICKNAME

so it will return OK/WARN/CRIT/UNKNOWN and corresponding exit code.

These links

  • Can be safely passed to your customers. They don’t reveal real dongle parameters like IMEI or Nickname.
  • They don’t require HTTP basic authentication
  • They depend on the proxy password. So, when you change the proxy password - old IP rotation links, associated with that proxy, will stop working.

A link can be copied from the WebApp→Ports list. Each Port has its own IP rotation link. If one port rotates IP, then other ports of the same modem affected too.

If you realized you gave a link to a customer, and want to revoke it, just set new password for the proxy.

If you want to invalidate all links of all modems, set a new secret: set RESET_LINK_SECRET in WebApp→GlobalSettings .

26. UDP support on Socks5 proxies, for QUIC / HTTP/3.0

On Proxysmart 2.3+ it is enabled by default.

It is needed for proper work of HTTP/3.0 which uses UDP.

QUIC (UDP over socks5) will work either in your LAN or via a VPS. Steps are below.

Steps on VPS :

Make sure you finished the Cloud VPS setup part, with Ansible 

cd /root/proxysmart-vps/
nano vars.txt

- set vps_socks5_udp: 1

Save the file (press Control O) and exit the editor (Control x)

Run Ansible again 

ansible-playbook ./proxysmart-vps.yml

Steps on Proxysmart server :

set in WebApp->GlobalSettings → QUIC_SUPPORT : On.

and reboot or reconfigure all proxies (run proxysmart.sh reset_complete ).

Note: make sure the VPS has enough RAM, each proxy needs 50MB of RAM. Also add swap if needed.

27. “Dirty” IP reset.

It may be needed when you need even faster IP reset. In this case, post-checks are not made, so it is not sure if the modem really went online after IP reset. It can be activated by DIRTY_IP_ROTATION in WebApp→GlobalSettings

28. Exclude some modems

In /etc/proxysmart/conf.txt

  • by Device name, populate this array IGNORED_DEV=( modem132 modem0000000002) – array of Network Interfaces that are not processed
  • by IMEI, populate this array IGNORED_IMEI=( 9999999999999999 8888888888888888 ) – array of IMEI that are not processed

29. Use custom Speedtest server.

It is useful when for some reason you want to run speed tests towards a custom server, instead of Ookla servers.

Update WebApp→Global_settings with IP of the WEB server:

  • SPEEDTEST_CUSTOM : enabled

DL_URL can be an URL of a large enough file (~100Mb+). And UL_URL is an URL that accepts large enough POST request.

30. Minimum time between IP rotations

If you want to avoid too frequent IP rotations triggered by your users – in WebApp→Global_settings set MINIMUM_TIME_BETWEEN_ROTATIONS as 120, so for 120 seconds minimum delay.

31. How to block domains

  • Individual (per proxy) block lists : WebApp → Edit Port, check DENIED_SITES_ENABLE, populate DENIED_SITES_LIST
  • Global block list - for all proxies: WebApp→Global_settings → check DENIED_SITES_ENABLE populate DENIED_SITES_LIST , click SAVE and re-apply all modems settings.

How blocklists are processed:

  • if you block porn.com, then also www.porn.com is blocked.
  • if you block gov, then also nyc.gov,www.nyc.gov are blocked.
  • IP's are blocked also e.g. 23.23.23.23

Note for Socks5 proxies

When a domain blacklist is imposed, then by default users still can access blocked sites by their IP’s.

In order to prevent it, set DENY_IP_REQUESTS in WebApp→Global_settings and run proxysmart.sh reset_complete for resetting all configuration (or reboot).

32. How to allow only whitelisted domains.

The feaure it not ready.

33. How to re-rotate IP when IP doesn’t change?

In WebApp→Global_settings set RETRY_IP_ROTATIONS .

So when Old_IP == New_IP, then IP rotation is retried. Up to MAX_RETRY_IP_ROTATIONS attempts which is by default 3.

34. Prevent non-unique IP’s after IP rotation.

For example to prevent using IP’s that were in use 1 time (or more) within last 24h: set in WebApp→Global_settings : 

RETRY_IP_ROTATIONS                 # enables Re-rotation, enable it.
NON_UNIQUE_IP_OCCURS 1             # how many times an IP must occur to be considered NonUnique. E.g. 1
NON_UNIQUE_IP_PERIOD 24hour        # during which period an IP must occur to be considered NonUnique. E.g. 1day or 1hour

35. How to enable client IP whitelisting?

On Proxysmart 2.3+ it is enabled by default

By default Proxysmart can't see original clients IP's. So we have to enable it:

Steps:

1. On Proxysmart server

  • set PROXY_PORTS_FORWARDER_SOFTWARE=ssh+haproxy in WebApp→Global_settings
  • run proxysmart.sh reset_complete for resetting all configuration.

2. On the VPS 

cd /root/proxysmart-vps/
nano vars.txt

set

haproxy_enabled: 1

Save the file (press Control O) and exit the editor (Control x)

Run Ansible again 

ansible-playbook ./proxysmart-vps.yml

36. Custom DNS server for the proxies

Edit /etc/proxysmart/conf.txt and set DNS_SERVER_PROXIES="1.1.1.1" where 1.1.1.1 is a custom DNS server, it must be publicly available.

Click the button “Reset Complete” on the main screen of the WebApp in the bottom or in the console, run: sudo proxysmart.sh reset_complete or reboot the server.

37. Where are proxy logs.

On the Proxysmart server in a folder /var/log/3proxy/ , each filename is named for HTTP proxy port.

Logs are rotated daily and 90 copies are saved, details are in /etc/logrotate.d/3proxy.

Logs of IP rotations are in a folder /var/log/proxysmart/dongle_rotations/.

38. No logs policy

If you want to run NoLogs policy, create a cron script that deletes the logs, i.e. the files 

/var/log/gost/*
/var/log/3proxy/*
/var/log/sniproxy*
/var/log/haproxy*

39. My proxies are slow.

Assume a chain UsbModem→PC→VPS→ProxyUser. Final Proxy speed is limited by:

  • Download speed of the modem
  • Upload speed from PC to VPS
  • Download speed from VPS to the ProxyUser

Download speed of the modem.

It can be measured on the side of the PC e.g. in the Proxysmart WebApp by clicking the Speedtest button.

How to improve it?

  • try other carriers
  • try other modems
  • try better location with better signal (i.e. not your Home)

Upload speed from PC to VPS.

Normally it correlates with quality of home internet (Fiber/xDSL) and can be measured by running speedtest on the PC in browser or in Terminal (speedtest-cli). Upload value has to be high.

With different types of port forwardings:

wan (Home Internet is used for ports forwarding) : remote proxy user's DownloadSpeed is limited to minimum of (ModemDownloadSpeed, HomeInternetUploadSpeed )

cell (each modem forwards its proxies through its internet) : remote proxy user's DownloadSpeed is limited to minimum of (ModemDownloadSpeed, ModemUploadSpeed )

How to improve it?

  • get a better home internet with better upload
  • switch from WiFi to Ethernet

Download speed from VPS to the ProxyUser

It can be measured by downloading a file from VPS to the Proxyuser.

How to improve it?

  • Change location of the VPS to a Cloud Hoster that has better reachability to the clients from all over the world

40. My proxies are slower than the same SIM card in a Phone.

Reason 1: Compare LTE category of the modem and the phone. Phone has higher LTE cat e.g. 12..20, while modem has LTE cat 4..6 (depends).

Reason 2: when the speed is really bad (about 1mbps) then it is Operator's throttling. Perhaps you bought a plan that allows only phones/tablets and doesn't allow modems.

41. How to forward proxy ports via each modem individually?

Why is it needed? When home base internet is unstable or its upload speed <15mbps.

A VPS is needed in order to expose the ports this way ( see VPS integration chapter ).

How it works

Each proxy forwards its port through its modem, not using base internet.

PRO's :

  • Home base internet speed & stability is not important

CON's :

  • each modem is working in bidirectional mode
  • proxy speed is limited to 4G Upload speed which is slow

Steps: on Proxysmart server

  • set PROXY_PORTS_FORWARDER_TYPE=cell in WebApp→Global_settings
  • run proxysmart.sh reset_complete for resetting all configuration.

42. Auto-rebooting modems.

Sometimes only a reboot can fix a modem. In order to enable, set AUTOREBOOT_DONGLES in WebApp→Global_settings. How it works:

  • if a situation occurs , “reboot score” of a modem is increased by the value, according to the situation:
SCORE_IP_ROTATION_FAIL=10                   # score increments when IP rotation failed
SCORE_IP_NOT_DETECTED=2                     # score increments when IP not detected
SCORE_IP_RECONNECT_FAIL=10                  # score increments when IP not auto-reconnected
SCORE_WWAN_DATA_FAIL=10                     # score increments when WWAN device can't establish Data connection
SCORE_WEBAPP_FAIL=20                        # score increments when the modem's WebApp is stuck
  • when the modem’s reboot score reaches MAX_REBOOT_SCORE then the modem is rebooted.
  • special case, do USB reset instead of a reboot, when AUTO_USB_RESET_DONGLES is 1, it is useful when modems’ WEB APP is not available.

43. My proxy is offline and showing Red in the WebApp.

  • Check if the modem has good signal.
  • Check if the modem has correct APN (set in its Web Dashboard).
  • Check if its SIM card is active (not blocked on Operator side) and is topped up.
  • Check the modem on another PC (e.g. your own Windows desktop) without WiFi and without Ethernet (to make sure Internet is provided by the dongle that being tested).

44. How to host multiple Proxysmart servers

When ports forwarded through a VPS

Assume 2 Proxysmart servers:

  • Server1
  • Server2

On each, make sure the proxies are configured on these ports:

  • Server1 : http 8001..8099, socks5 5001..5099
  • Server2 : http 8101..8199, socks5 5101..5199

Make settings in the WebApp→GlobalSettings:

For Server1:

  • VPS - IP of the VPS
  • PROXY_PORTS_FORWARDER_ENABLE on
  • SSH_REMOTE_PORT: 6001
  • WEB_REMOTE_PORT: 7001
  • OPENVPN_SERVER_PORT: 1501

For Server2:

  • VPS - IP of the VPS
  • PROXY_PORTS_FORWARDER_ENABLE on
  • SSH_REMOTE_PORT: 6002
  • WEB_REMOTE_PORT: 7002
  • OPENVPN_SERVER_PORT: 1502

When ports forwarded through a static office IP

Assume 2 Proxysmart servers:

  • Server1, LAN_IP1
  • Server2, LAN_IP2

On each, make sure the proxies are configured on these ports:

  • Server1 : http 8001..8099, socks5 5001..5099
  • Server2 : http 8101..8199, socks5 5101..5199

Then on the router, make forwardings.

For Server1:

  • WebApp: (from external IP) TCP 8080→LAN_IP1:8080
  • Proxies: (from external IP) TCP 8001..8099,5001..5099 → LAN_IP1
  • Openvpn: (from external IP) TCP+UDP 1194→LAN_IP1:1194

For Server2:

  • WebApp: (from external IP) TCP 8082→LAN_IP2:8080
  • Proxies: (from external IP) TCP 8101..8199,5101..5199 → LAN_IP2
  • Openvpn: (from external IP) TCP+UDP 1195→LAN_IP2:1194

45. IP's are rotated on their own

If you don't rotate IP's and they are detected each time as a new IP - it is natural behaviour of mobile provider, when it routes its clients through random different gateways every 1 minute or so. T-Mobile USA is known of doing so.

Solution: in the WebApp→GlobalSettings set COLLECTD_PINGER_KEEPALIVE to On, so there will be a pinger daemon that keeps open connection to a hostname defined as COLLECTD_PINGER_HOSTNAME through each modem.

46. Install logging of all requests in single place

Why? Get single log of all requests from Proxies (HTTP/Socks5) clients and VPN clients.

Installation On Proxysmart server

In the WebApp→GlobalSettings set SNIFFER_ENABLED and click Apply.

run proxysmart.sh reset_complete

Watch the log /var/log/proxy_log.log on Proxysmart server.

It is rotated and 365 daily copies are stored on disk.

Then it is bound to a button “Download Proxy Logs”.

It can also be installed on a VPS if the VPS is working as proxies frontend.

47. PPP modems

These are very old 3g modems like Huawei E303, E173, E156; ZTE MF110, MF193, MF190. In order to make them work with proxysmart,

edit WebApp→GlobalSettings and set PPP_MODEMS_ENABLE .

Make Quectel / Sierra Wireless LTE modules work in PPP mode

Why? sometimes they fail working in QMI mode. So:

  • edit WebApp→GlobalSettings and set PPP_MODEMS_ENABLE
  • place a file /etc/udev/rules.d/21-wwan.rules
# ignore QMI_WWAN endpoints on Quectel, to make it work in PPP mode.
SUBSYSTEM=="net", ACTION=="add",  ATTRS{idVendor}=="2c7c" , ATTRS{idProduct}=="0125",  ENV{.LOCAL_ifNum}=="04", PROGRAM="/usr/local/bin/usb_ignore.sh %p"
# ignore QMI_WWAN endpoints on SierraWireless  , to make it work in PPP mode. Save to 21-wwan.rules:
SUBSYSTEM=="net", ACTION=="add",  ATTRS{idVendor}=="413c" , ATTRS{idProduct}=="81b6",  ENV{.LOCAL_ifNum}=="08", PROGRAM="/usr/local/bin/usb_ignore.sh %p"
  • re-plug modems or reboot Proxysmart server

48. Alerts to Telegram

In Telegram start a chat with a bot https://t.me/userinfobot and get your Telegram numeric ID.

In Proxysmart WebApp→GlobalSettings , set TG_ALERTS_ENABLE ; and set TG_ALERTS_RECEIVER to your Telegram numeric ID.

In Telegram start a chat with Proxysmart bot https://t.me/nagios737bot and send 'hi'.

After that the bot will send you alerts.

49. Mobile VPN

Together with building proxies, it is possible to build Mobile VPN.

It is enabled with WebApp→GlobalSettings → OpenVPN integration → OPENVPN_INTEGRATION

49.1. Mobile VPN, how to connect

So download the VPN profiles and connect using any VPN client software.

  • Download and install software:

Windows: https://openvpn.net/community-downloads/ or https://openvpn.net/client-connect-vpn-for-windows/

MacOS: https://tunnelblick.net/

Android: https://play.google.com/store/apps/details?id=de.blinkt.openvpn or https://f-droid.org/en/packages/de.blinkt.openvpn/

IOS: https://apps.apple.com/us/app/openvpn-connect/id590379981

  • Import downloaded OpenVPN profile, tap Connect.
  • use Login and Password from the corresponding proxy.

49.2. Mobile VPN, Switch Openvpn protocol

  • You can switch to TCP or UDP.
  • In WebApp→GlobalSettings set OPENVPN_PROTOCOL to tcp or udp and run proxysmart.sh reset_complete
  • On Clients, either download profiles again, or change protocol in client settings.

49.3. Mobile VPN logs

Logs of openvpn sessions - /var/log/openvpn/sessions.log. Format: 

'$time','$type','$local_port','$proto','$duration','$bytes_in','$bytes_out','$Real_IP','$Real_PORT','$Ovpn_CERT','$Ovpn_IP','$IMEI','$proxy_login','$auth_reject_why'
  • type - session_start / session_stop / auth_reject
  • local_port - local port of Openvpn server
  • proto - tcp-server or udp
  • duration - when type is session_stop, how many the session lasted
  • Real_IP, Real_PORT - of a client
  • auth_reject_why - when type is session_stop, the reason why auth was rejected

9. Bugs and Limitations

LTE modules

  • IPV6 is not supported

Android phones

  • No P0f-spoofing with Proxysmart APK app.
