I have developed a software that allows you to run your own 4g proxy farm. It runs on a Linux box (PC) with USB hub and the modems.

Functions:

• IP resets on modems
• WebApp for checking status of each modem
• WEBAPI for actions like querying status, IP rotation, getting used bandwidth for the day, running speedtests
• setting bandwidth quota per modem per month
• bandwidth throttling per modem
• exposing proxy ports, so they are available from world wide
• readingSMS and USSD
• OS spoofing, to simulate TCP fingerprints of: MacOS  iOS  Windows  Android
• custom MTU per modem
• proxy ACLs (what to allow/deny to proxy users)

Variables are set /etc/proxysmart/conf.txt.

Each variable has brief description in place.

• 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 /etc/proxysmart/conf.txt. 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 or run sudo proxysmart.sh reset_gently
• the modem will appear in the WebApp, click EDIT on it, assign some unique Nickname, HTTP & SOCKS5 ports, Login and Password, then click APPLY
• refresh the WebApp
• done!

Make sure LAN_MODEMS_ENABLE=1 is in /etc/proxysmart/conf.txt.

Configure the server with 2 LAN cards

Assume you have 2 LAN cards, 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 disabled 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:

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 /etc/proxysmart/conf.txt in DEFAULT_HILINK_ADMIN_PASSWORD variable.
• Change the modem’s IP to something unique e.g. 192.168.10.10
• Put the modem into Ethernet switch routed to the Proxysmart server.
• On the Proxysmart server make sure you can ping the new modem by its IP you set in previous step.

On the server, edit the /etc/proxysmart/lan_modems.yaml file, add a line

- { gw: 192.168.10.10, dev: lanmodem10 }

The line contains its unique IP and the word lanmodem10 ( constructed from a word lanmodem plus a unique number ).

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

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=1 is in /etc/proxysmart/conf.txt.

Edit /etc/proxysmart/backend_proxies.yaml , post lines like these:

- id: bproxy1
  creds: http://lll:[email protected]:8100
  ip_reset: 'http://x.x.x.x:8083/api/changeIp?cool'

- id: bproxy2
  creds: https://lll:[email protected]:3129

Where:

1. id has to be in the form 'bproxy' + a number
2. creds is a line with credentials of the backend proxy
3. ip_reset is an optional parameter , the URL for triggering IP rotation of the backend proxy

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

When adding new modems, please use

• unique HTTP ports from 8001 to 8999,
• unique SOCKS ports from 5001 to 5999.

If you want different ports ranges, update firewall.conf accordingly.

• please use unique nicknames like dongleXXX or whatever else. Don’t use nicknames like randomXXX, that are assigned automatically.

One of

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

By default login/password are proxy / proxy.

• 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.

Run: proxysmart.sh show_status for table-alike output.

Run: proxysmart.sh reset_complete

It is done after reboot automatically by a Cron job.

WebApp method

• click EDIT on a modem, set new port or password or nickname for a modem
• click APPLY

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.

For global setting, edit /etc/proxysmart/conf.txt and set AUTO_IP_ROTATION=5 in order to rotate each modem every 5th minute. If set to 0, automatic IP rotation is not done. You can also set hourly rotation, set 120 for every 2h rotation.

• 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.

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

In some cases custom TTL must be set in order to have Cell Operator think we are not using the modem in hotsport  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 /etc/proxysmart/conf.txt and set CUSTOM_TTL_SET=1 and CUSTOM_TTL_VALUE=65 and regenerate settings.

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.

- Edit /etc/proxysmart/conf.txt and set CUSTOM_MTU_SET=1 . - Set MTU in the WebApp for each modem.

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 bits per second. E.g. 2/2 mbps will be 2000000/2000000.
• DENIED_SITES_ENABLE (1 or 0) and DENIED_SITES_LIST (list of blocked sites patterns).
• Bandwidth Quota, (in Megabytes)
• MTU

Open WebApp. Locate the modem. Configure a proxy on your desktop browser.

Use proxy login & password as desribed below (14.1 chapter).

Visit modem IP via that proxy.

Since 2023-09-10 it is enabled by default.

Edit /etc/proxysmart/conf.txt and set

PROXY_ADMIN_ENABLE=1
PROXY_ADMIN_LOGIN=SuperAdmin
PROXY_ADMIN_PASS=Hqmz81mmZr

And regenerate configs. So only admin user is allowed to use modems web interfaces, and normal proxy users are not.

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

Set OPEN_PROXIES=1 in /etc/proxysmart/conf.txt 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.

Click bandwitdh stats in the WebApp, or run proxysmart.sh bandwidth_report_json dongleXXX, you will see these columns:

• “bandwidth_bytes_day_in”
• “bandwidth_bytes_day_out”
• “bandwidth_bytes_month_in”
• “bandwidth_bytes_month_out”
• “bandwidth_bytes_yesterday_in”
• “bandwidth_bytes_yesterday_out”

Run a command

ss -o state established | grep -c :8038

But change 8038 with HTTP port of a desired proxy

You have these options.

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

By default it is set to proxy / proxy. The password sits on the server’s folder /etc/nginx/. It Can be updated from the Terminal , with the command as follows:

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

Then it will ask for password for current Ubuntu user.

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 /etc/nginx/htpasswd MyNewUsername NewAweSomePassword999999

How to change WEB port

edit /etc/nginx/sites-enabled/proxysmart.nginx and set other port and restart Nginx.

Os Spoofing is used to simulate other OS TCP fingerprints, MacOS  iOS  Windows  Android

How to enable OS Spoofing?

In the WebApp set destination OS per each modem.

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

What OS can I spoof?

MacOS  iOS  Windows  Android

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.

When >10 modems are added, and when modem list is generated slowly, play with MAX_PARALLEL_WORKERS_STATUS variable, e.g. set it to 2 or 4. On faster CPU’s it can be set to 8.

Also try to disable OS TCP reporting, i.e. set ENABLE_VALDIK=0 in /etc/proxysmart/conf.txt. It will also make modem list generation faster.

Also you can disable detailed status, set QUICK_STATUS=1 in /etc/proxysmart/conf.txt & refresh the WebApp.

Set TARGET_MODE in its settings in the Proxysmart WebApp. Allowed values:

• auto
• 3g
• 4g

Rotate its IP.

In the WebApp, click EDIT on a modem, add some extra users, click APPLY.

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 /etc/proxysmart/conf.txt with

• ALTNETWORKING_VERSION=2
• IPV6_SUPPORT=1

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

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 have limited lifetime , it is set in /etc/proxysmart/conf.txt as RESET_LINK_VALIDITY variable, (default value : 5 years).
• They depend on proxy password. So, when you change proxy password - old IP rotation links will stop working.

A link can be retrieved this way: Open dongle status (click on its IMEI!) in the WebApp, take RESET_SECURE_LINK→URL value.

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 /etc/proxysmart/conf.txt .

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.

Run:

install logrotate rule so Gost logs won’t fill up the disk space.

echo '
/var/log/gost/*.log {
    missingok
    compress
    notifempty
    hourly
    rotate 48
    copytruncate
}
' > /etc/logrotate.d/gost

echo '35 * * * * root /usr/sbin/logrotate -v /etc/logrotate.d/gost' > /etc/cron.d/gost-logrotate 

Install sudoers so proxysmart server can run commands with sudo on the VPS:

echo 'fwd  ALL=NOPASSWD:  ALL' >  /etc/sudoers.d/proxysmart 
chmod 400 /etc/sudoers.d/proxysmart
usermod -s /bin/bash fwd

Install Gost v2

ARCH=linux-amd64
VER=2.11.3
curl -L -o /tmp/gost.gz https://github.com/ginuerzh/gost/releases/download/v$VER/gost-$ARCH-$VER.gz
gunzip -dc /tmp/gost.gz  > /usr/local/bin/gost.new
chmod 755 /usr/local/bin/gost.new
mv  /usr/local/bin/gost.new /usr/local/bin/gost
gost -V

Install Gost v3

VER=3.0.0-rc8
ARCH=linux_amd64
URL="https://github.com/go-gost/gost/releases/download/v$VER/gost_${VER}_$ARCH.tar.gz";
D=`mktemp -d`;
( cd $D;
  curl -L -o /tmp/gost3.tgz "$URL";
  tar xf /tmp/gost3.tgz gost;
  mv gost /usr/local/bin/gost3.new 
  );
rm -rf $D;
chmod 755 /usr/local/bin/gost3.new;
mv /usr/local/bin/gost3.new /usr/local/bin/gost3;
gost3 -V

if Haproxy is not installed, do nothing.

if Haproxy installed: free up SOCKS ports (5xxx) from Haproxy: edit /etc/haproxy/haproxy.cfg and delete section frontend fe_SOCKS5 and restart it systemctl restart haproxy.service

set in /etc/proxysmart/conf.txt :

• QUIC_SUPPORT=1
• GOST_VER=gost

and run proxysmart.sh reset_complete.

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

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=1 in /etc/proxysmart/conf.txt.

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

It is useful when for some reason you want to run speed tests towards a custom server, instead of Ookla servers. So set up a Apache web server with a large file (500MB) and get 2 URL’s, one will test download and 2nd will test upload. The latter must accept large POST data.

The commands to setup a server part

apt install apache2
dd if=/dev/urandom  of=/var/www/html/file.bin bs=1M count=500

Update /etc/proxysmart/conf.txt with IP of the WEB server:

SPEEDTEST_CUSTOM=1  
DL_URL=http://$VPS/file.bin
UL_URL=http://$VPS/i.php

If you want to avoid too frequent IP rotations triggered by your users – set MINIMUM_TIME_BETWEEN_ROTATIONS=120 e.g. for 120 seconds minimum delay in /etc/proxysmart/conf.txt .

• Check (enable) DENIED_SITES_ENABLE in the WebApp
• DENIED_SITES_LIST is a list of domains that will be blocked, both HTTP and HTTPS, plus their subdomains. E.g. if you list porn.com, then also www1.porn.com,www.porn.com,porn.com are blocked.

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=1 and VERSION_3PROXY=0.9 in /etc/proxysmart/conf.txt and run proxysmart.sh reset_complete for resetting all configuration.

• Check (enable) WHITELIST_SITES_ENABLE in the WebApp
• WHITELIST_SITES_LIST is a list of domains that are allowed, while other are blocked. Both HTTP and HTTPS, plus their subdomains. E.g. if you list bbc.com, then also www.bbc.com,www1.bbc.com are listed.

In /etc/proxysmart/conf.txt set RETRY_IP_ROTATIONS=1 .

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

For example to prevent using IP’s that were in use 1 time (or more) within last 24h: set in /etc/proxysmart/conf.txt :

RETRY_IP_ROTATIONS=1                 # enables Re-rotation
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

Why? In order to enable client IP whitelisting, i.e. 3proxy on proxysmart server will see original client IP and will be able to use whitelising.

Steps:

1. On Proxysmart server

• set PROXY_PORTS_FORWARDER_SOFTWARE=ssh+haproxy in /etc/proxysmart/conf.txt
• run proxysmart.sh reset_complete for resetting all configuration.

2. On the VPS

Run apt install haproxy rsyslog

3. Copy Haproxy and Syslog conf files from the Proxysmart server files to the VPS

scp them from the Proxysmart server to the VPS. $VPS variable is sourced from the conf.txt

source /etc/proxysmart/conf.txt
cd /usr/share/doc/proxysmart/examples/haproxy_integration/
scp etc/haproxy/haproxy.* $VPS:/etc/haproxy/
scp etc/rsyslog.d/49-haproxy.conf $VPS:/etc/rsyslog.d/

4. On the VPS

Run

touch /var/log/haproxy.log
chown syslog:syslog /var/log/haproxy.log 

systemctl restart rsyslog.service 
systemctl restart haproxy.service 
systemctl status haproxy.service

Must be green and show active(running).

5. Post check

Test a proxy via VPS IP and you will original client IP in 3proxy logs.

Edit /etc/proxysmart/conf.txt , set VERSION_3PROXY=0.9 , run proxysmart.sh reset_complete.

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/.

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*

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

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

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.

How to improve it?

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

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

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.

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 /etc/proxysmart/conf.txt
• run proxysmart.sh reset_complete for resetting all configuration.

Sometimes only a reboot can fix a modem. In order to enable, set AUTOREBOOT_DONGLES=1 in /etc/proxysmart/conf.txt. 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.

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 desktop).

Edit /etc/proxysmart/conf.txt , set PARALLEL_STARTUP=1 .

So the modems are processed in parallel, in the number of threads defined in MAX_PARALLEL_WORKERS_STATUS variable (default 8).

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.

*the Goal*

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

Installation On Proxysmart server

Edit /etc/proxysmart/conf.txt , set SNIFFER_ENABLED=1 .

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.

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

Installation On VPS

Required files (copy from Proxysmart server to the VPS):

/usr/local/bin/proxy_log.sh
/etc/systemd/system/proxy_log.service
/etc/logrotate.d/proxy_log

run :

apt update && apt install tshark
systemctl enable proxy_log --now 

Watch the log /var/log/proxy_log.log on VPS.

Log format

File: /var/log/proxy_log.log

    _ws.col.Time  frame.interface_name   ip.src  tcp.srcport   ip.dst   tcp.dstport  
    #   1          2                        3       4           5           6
    
    socks.remote_name    socks.dst    socks.port   socks.dstport

    #   13                                  14

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

edit /etc/proxysmart/conf.txt and set PPP_MODEMS_ENABLE=1 .

Make Quectel LTE modules work in PPP mode

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

• edit /etc/proxysmart/conf.txt and set PPP_MODEMS_ENABLE=1
• 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"

• re-plug Quectel modems or reboot Proxysmart server

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

• 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. The URL is defined in /etc/proxysmart/conf.txt.
• http://witch.valdikss.org.ru/ : used for detecting p0f and MTU

Show full status of all modems, table (slower).

Mongodb contains a collection modems with elements, 1 element = 1 modem.

Mandatory fields are

• IMEI
• name
• http_port
• socks_port
• proxy_login
• proxy_password

Other fields are optional.

After editing a record in Mongodb, apply settings for the edited modem ( /modem/settings WEB API call).

Sample file modems.json with 2 modems. 1st modem: only mandatory fields. 2nd modem: also arbitrary fields.

Sometimes you want to move Mongodb to a cloud server.

In order to do so

• keep collection name modems
• if your new mongodb is Mongodb 5+ and doesn’t have backward compatibility with the older clients, upgrade Mongodb Client to 5th version. Run on the Proxysmart box:

apt purge mongo\* -y
. /etc/os-release 
rm -f /etc/apt/sources.list.d/mongodb*
curl -L https://www.mongodb.org/static/pgp/server-5.0.asc | gpg --dearmor | sudo dd of=/etc/apt/trusted.gpg.d/mongodb-5.0.gpg
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu $VERSION_CODENAME/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list 
apt-get update
apt install mongodb-mongosh mongodb-database-tools -y
ln -sf /usr/bin/mongosh /usr/local/bin/mongo

• 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]"
• test new Mongodb URI (I assume you updated MONGODB_URI variable in conf.txt above):

    . /etc/proxysmart/conf.txt;
    mongoexport --quiet --uri="$MONGODB_URI" -c modems --forceTableScan

it should return array of all elements in the modems collection

• systemctl restart proxysmart
• proxysmart.sh reset_complete

Install a fresh OS.

Supported OS and architectures:

• Ubuntu 22.04, 20.04 on amd64, arm64.
• Debian 11 or Raspberry PI OS (ex-Raspbian) on amd64, arm64, armhf ( see Raspberry PI OS Notes below).
• Raspberry PI : https://ubuntu.com/download/raspberry-pi , choose Ubuntu Server 22.04 64bit
• Normal PC/laptop: Choose Server or Desktop, https://ubuntu.com/download, choose Ubuntu 22.04

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

Those steps will take 5..10 minutes.

Unplug any 4g modems.

Add an APT repo.

wget -O-  https://pathos.tanatos.org/proxysmart.apt.repo/GPG.txt | \
    gpg --dearmor | sudo dd of=/etc/apt/trusted.gpg.d/proxysmart.gpg

source /etc/os-release
ARCH=$(dpkg --print-architecture)

echo "deb [arch=$ARCH] http://pathos.tanatos.org/proxysmart.apt.repo $VERSION_CODENAME main" \
    | sudo tee /etc/apt/sources.list.d/proxysmart.list

sudo apt update
sudo apt install proxysmart

Then follow instructions: It will tell what to do next ( run 2 files ).

sudo /usr/lib/proxysmart/install_pkgs.sh
sudo /usr/lib/proxysmart/install_webapp.sh

Reboot or run sudo proxysmart.sh reset_complete.

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

Rockpi Notes

If LOGRAM is enabled ( a folder /var/log.hdd exists). Disable logging:

• mongodb, edit /etc/mongodb.conf, comment logpath directive.

Raspberry PI OS (ex-Raspbian) Notes

its kernel doesn't have xt_cgroup module , so you have to rebuild its kernel and include this module. It is recommended to switch to Ubuntu instead.

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

wget -O-  https://pathos.tanatos.org/proxysmart.apt.repo/GPG.txt | \
    gpg --dearmor | sudo dd of=/etc/apt/trusted.gpg.d/proxysmart.gpg

source /etc/os-release
ARCH=$(dpkg --print-architecture)

echo "deb [arch=$ARCH] http://pathos.tanatos.org/proxysmart.apt.repo.dev $VERSION_CODENAME main" \
    | sudo tee /etc/apt/sources.list.d/proxysmart.list

sudo apt update 
sudo apt install proxysmart
sudo /usr/lib/proxysmart/install_pkgs.sh
sudo /usr/lib/proxysmart/install_webapp.sh

Reboot or run sudo proxysmart.sh reset_complete.

Run these commands:

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.

sudo -i
wget -O-  https://pathos.tanatos.org/proxysmart.apt.repo/GPG.txt | gpg --dearmor | dd of=/etc/apt/trusted.gpg.d/proxysmart.gpg
apt update 
apt install proxysmart
/usr/lib/proxysmart/install_pkgs.sh
/usr/lib/proxysmart/install_webapp.sh

Reboot or run sudo proxysmart.sh reset_complete.

Plug in all 4g modems you have, wait ~20 sec to let them initialize.

Now test if ip li shows you any modem* interfaces, otherwise reboot to apply UDEV rules.

If it does, continue next below. (Otherwise reboot to apply UDEV rules.)

Now you can start all the modems:

You have to run proxysmart.sh reset_complete or reboot the multi-modem server.

Command proxysmart.sh show_status will return a table with proxy port, external IP’s.

Navigate to the WebApp http://localhost:8080 proxy/proxy and assign login/password/nicknames/ports to the modems.

Test reboot, reboot the box, wait 1 minute, make sure the WebApp shows the modems.

WebApp

Visit http://your_box_lan_IP_address:8080/ or http://localhost:8080/

Default user:password pair is proxy:proxy

Why? The VPS is needed to forward proxy ports from a cloud VPS IP back to the multi modem server, so proxy ports are available for all users around the world.

A VPS is NOT needed when all the conditions are met:

• you have static IP at 4g proxy farm location, i.e. ISP provides it, and
• ISP allows incoming connections to that static IP
• Upload and Download of “ground” Internet is at least 20 Mbps.

Without a VPS, you can forward proxy ports on your Home/Office router to multi-modem server in the LAN. In that case users from around the world will connect to your static IP, so these connections are forwarded to the 4g farm server situated in the LAN.

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 ).

Copy content from the file /root/.ssh/fwd.pub [1]

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

Create a user fwd , run :

useradd -s /bin/true -m fwd
usermod -p '*' fwd
mkdir -p /home/fwd/.ssh/
touch /home/fwd/.ssh/authorized_keys
chown -R fwd: /home/fwd/
chmod 700 /home/fwd/.ssh/
chmod 600 /home/fwd/.ssh/authorized_keys

Adjust SSH server configuration, run :

mkdir -p /etc/ssh/sshd_config.d
echo '
GatewayPorts clientspecified
ClientAliveInterval 3
ClientAliveCountMax 3
MaxStartups 100:30:1000
LoginGraceTime 10
' > /etc/ssh/sshd_config.d/proxysmart.conf

service ssh restart

edit the file and paste the content [1] you copied in the step above. It is public part of fwd.ssh key that is used for communication from Proxysmart to VPS.

nano /home/fwd/.ssh/authorized_keys

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

in /etc/proxysmart/conf.txt :

• set VPS variable to VPS IP
• set PROXY_PORTS_FORWARDER_ENABLE=1
• run proxysmart.sh reset_complete
• edit /etc/systemd/system/fwdssh-vps.service , change CONNECT_HOST to VPS IP
• Pick a free port for SSH_REMOTE_PORT, in most cases 6902 is fine.
• Pick a free port for WEB_REMOTE_PORT, in most cases 8080 is fine.

Run:

systemctl daemon-reload
systemctl start fwdssh-vps
systemctl enable fwdssh-vps
systemctl status fwdssh-vps

Make sure it is green.

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

• visit http://vps_ip:8080 for the WebApp , default login:password is proxy:proxy
• you can ssh to VPS IP and port 6902, and that goes to the multi-modem-server:22.

If CLoud VPS IP is changed, update it on multi-modem-server side by defining new VPS variable in the /etc/proxysmart/conf.txt file, and rerun proxysmart.sh reset_complete there.

Also change VPS IP in /etc/systemd/system/fwdssh-vps.service on multi-modem-server and run these:

systemctl daemon-reload
systemctl restart fwdssh-vps
systemctl status fwdssh-vps

Make sure it is green.

Why? It is needed to forward proxy ports from a your ISP IP address back to the multi modem server, so proxy ports are available for all users around the world.

It is suitable when all the conditions are met:

• you have static IP at 4g proxy farm location, i.e. ISP provides it, and
• ISP allows incoming connections to that static IP
• Upload and Download of “ground” Internet is at least 20 Mbps.

Without a VPS, you can forward proxy ports on your Home/Office router to multi-modem server in the LAN. In that case users from around the world will connect to your static IP, so these connections are forwarded to the 4g farm server situated in the LAN.

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
• TCP 1194 for Openvpn (if it is working in TCP mode)
• UDP 1194 for Openvpn (if it is working in UDP mode)

Notes

Also edit /etc/proxysmart/conf.txt . Replace myrouter.com with your actual Hostname or IP addresss.

So proxy credentials & links will be shown with your actual Hostname or IP addresss.

PROXY_PORTS_FORWARDER_ENABLE=0
REWRITE_WEBAPP_URL=1
REWRITE_WEBAPP_TO="http://myrouter.com:8080"
REWRITE_HOST_IN_PROXY_CREDS=1
REWRITE_HOST_IN_PROXY_CREDS_TO="myrouter.com"

run

systemctl disable --now gost_forward_vpn
systemctl disable --now fwdssh-vps

.. so forwarding system ports to a VPS is disabled.

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

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.

Method1. From the WebApp:

• Open the proxysmart WebApp at http://localhost:8080 or http://LAN_IP:8080
• Expand License section
• Copy machine_data value

Method2. From the CLI:

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

Send the copied value to proxysmart.org

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

If your paid license expired or broken, restore DEMO license, run:

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

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

Assumption is, your proxies are already available via Cloud VPS.

If ports forwarded through a VPS

Steps on VPS

Assume the VPS is already “integrated” - see VPS integration topic.

Pick a free TCP port on the VPS, run ss -tnlp on the VPS and it will show USED ports, so pick up a free one e.g. 1501. We will call it OPENVPN_REMOTE_PORT.

Steps on Proxysmart server

• edit /etc/systemd/system/fwdssh-vps.service
• uncomment and set Environment=OPENVPN_LOCAL_PORT=1194
• uncomment and set Environment=OPENVPN_REMOTE_PORT=1501 , to the OPENVPN_REMOTE_PORT from the step above.
• edit /etc/proxysmart/conf.txt and set OPENVPN_SERVER_PORT=1501 , to the OPENVPN_REMOTE_PORT from the step above.
• set OPENVPN_INTEGRATION=1

So VPN client certificates will be generated with this value, so VPN clients will connect there ( $VPS_IP:$OPENVPN_REMOTE_PORT/TCP )

systemctl daemon-reload
systemctl restart fwdssh-vps

This just enabled port forwarding of TCP port OPENVPN_REMOTE_PORT to localhost:OPENVPN_LOCAL_PORT.

Then run /usr/lib/proxysmart/install_openvpn.sh , it will do the installation of Openvpn server.

Check if /etc/openvpn/server.conf has proto tcp otherwise set it there.

Check if /etc/openvpn/client.ovpn.template has proto tcp and proper remote (with VPS IP and OPENVPN_SERVER_PORT) otherwise set it there.

Then finally reconfigure the system by running proxysmart.sh reset_complete . For each modem it will generate a VPN profile.

Restart proxysmart WebApp so it shows a web link for downloading the profiles systemctl restart proxysmart .

You can download them later as from the WebApp at http://localhost:8080/vpn_profiles/ or grab from /home/vpn/ folder.

If ports forwarded through the LAN router

Steps on LAN router

Your external IP of the LAN router is $EXT_IP .

You forwarded TCP port 1194 to the LAN IP of the Proxysmart server. We will call it OPENVPN_SERVER_PORT.

Steps on Proxysmart server

• edit /etc/proxysmart/conf.txt and set OPENVPN_SERVER_PORT=1194 , to the OPENVPN_SERVER_PORT from the step above.
• set OPENVPN_INTEGRATION=1

So VPN client certificates will be generated with this value, so VPN clients will connect there ( $EXT_IP:$OPENVPN_SERVER_PORT/TCP )

Then run /usr/lib/proxysmart/install_openvpn.sh , it will do the installation of Openvpn server.

Check if /etc/openvpn/server.conf has proto tcp otherwise set it there.

Check if /etc/openvpn/client.ovpn.template has proto tcp and proper remote (with $EXT_IP and OPENVPN_SERVER_PORT ) otherwise set it there.

Then finally reconfigure the system by running proxysmart.sh reset_complete . For each modem it will generate a VPN profile.

Restart proxysmart WebApp so it shows a web link for downloading the profiles systemctl restart proxysmart .

You can download them later as from the WebApp at http://localhost:8080/vpn_profiles/ or grab from /home/vpn/ folder.

If you need 2 extra VPN profiles for a dongle dongle1 , run openvpn_create_user dongle1@a or openvpn_create_user dongle1@b .

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.

By default only 1 device (PC, mobile, tablet) can use 1 OpenVPN profile. If you want multiple devices use 1 profile, edit /etc/openvpn/server.conf , comment out ;duplicate-cn line by removing the ; character, and run proxysmart.sh reset_complete.
