4G\LTE proxy farm on your own hardware

Jan 2022

Create your own residential proxies with multiple 4G\LTE USB modems. Mobile Proxies farm consist of a server box (it can be a Raspberry Pi or a Mini PC or a used laptop), a USB hub, and several 4G modems, where each modem is attached to its dedicated proxy address.

3proxy socks5 configuration

Jan 2022

I need some assistance with configuring the socks5 3proxy. The current issue when connecting from allowed ip the source ip is not getting replaced.

Setup multiple 4g Proxy Server Raspberry PI

Nov 2021

A Raspberry PI runs in the local network and provides different 4G connections. The Raspberry is already running and Squid is installed, but it does not work as desired. And if it works, then only via a USB dongle and not via different ones. The proxies should be accessible via port and password in the internal network. The dongles are from Huawei and create their own network as soon as the internet connection is established. The dongles are already set up and configured to create different networks when they connect. Probably only the Squid configuration and routing needs to be adjusted.

I can offer a Teamviewer access to a Windows machine. The PI can be reached via SSH. The PI should not be reachable from the Internet.

Software Development of a 4G Network Farm

Jul 2021

We’re looking to create our own 4g proxy farm, and we would like for you to build the software that would automatically convert the modem into a proxy. an API that would allow us to swap from static to rotating IPs would be ideal and we would love for it to work with the classic Huawei modems for this use case.

Setup of 4G mobile proxy hard & software

Jul 2021

We are currently looking for a well-motivated person who can assist us with setting up a network 4G proxies by using 5 to 10 sim cards.. He/she can help us with the following tasks :

• Coming up with the best setup
• We can provide you with the budget and 4G sim cards with unlimited data subscriptions (fair use policies apply here)
• Suggest us on correct dongle (country band) + hardware setup
• Install are required software, help us step by step
• We will install in our home address, so you will not have physical access to them.
• When done: Create API or similar service which allows us to connect the 4G proxies to our existing code
• We need to be able to refresh IP upon request and keep track of which IP was used where and when

Various devops/development related tasks

Jan 2021

Pavel and I have worked on past projects and it’s always positive. He has exceptional technical skills and is very professional. We will continue to use him.

1) create live cd for centos 8 based on the work done prior for centos 7 and ubuntu 18.04

2) write scripts for both ubuntu and centos versions to automate the creation of custom packages that will be installed through the live cd creation process of our prior work.

Mobile proxies management system

Dec 2020

Pavel is very professional and dedicated. I contacted him for a critical problem regarding web, proxy and CLI programming. He was able to figure out the problem. The whole process from problem proposal to solution offering takes less than 24 hours. Thank you for your work and fast availability

Scripts to Create Customizable minimal LiveCD images for Ubuntu and Centos

Aug 2020

I’ve used Pavel before, and I’ll continue to do so in the future. He’s an A player for sure. I highly recommend him.

2 sets of deliverables will include the following for an ubuntu 18.04 os and a centos 7 os Live CD:

-scripts used to build each Live CD release which will also include removal of non-essential packages. the goal is to enable network connectivity functionality as a client and not a server.
-no gui’s installed – this is a headless, minimal linux instance
-the build process should allow for the additional of other packages before “sealing” it as a live CD
-iso image to use as a base. Note that the iso used must permit UEFI boot.
-images will be VM’s that will be able to run under VMWare Worstation
-scripts to seal the image as a live cd and generate an iso image

Help me fix my Squid.conf file to have different ports for different users

Jun 2020

Helped me configure my squid.conf file in a way that no one else managed to. I tried every stack exchange and a few freelancing sites and he was the only one who could solve this. Recommended.

I have a pretty basic squid configuration on a Linux machine where Squid listens to multiple ports, I want to change my config so that each port has it’s own user and other users can’t log in.

Setup Caddy V2 to handle vanity domains with SSL for our app

Jun 2020

Pavel is extremely knowledgeable and fast, he can figure things out on his own. I would rehire him anytime when needed.

I’m looking for someone to set up a reverse proxy using caddy v2 for an app we have.
our app handles custom subdomains for our customers and we added custom domains / vanity domain, but we can’t handle SSL yet, and we have been recommended to use caddy for this.

Automate Debian Linux Networking

May 2020

I am looking for Scripting and System Configuration for a Debian Linux (Buster) Distribution running on Raspberry Pi (A+, Pi Zero W). The Host (Raspberry Pi 3A+) and the Slave (Raspberry Pi Zero W) will be connected using g-ether on the Host and via USB Gadget Mode on the Slave. Both the Host and the Slave are running Avahi. This project will consist of Two Deliverables.

The first deliverable is a Script to set up the following (at boot and on-going) on the Host: On Detection, assign USB0 a valid IP Address (IPv4) and start network (IPTABLES) NAT Forwarding from the subnet assigned to USB0 with a destination of wlan0 (it is not a requirement it use WLAN0 as long as it can use WLAN0 or ETH0). On disconnection of USB0, disable NAT and Forwarding from Subnet.

The second deliverable is a Script to set up the following (at boot and on-going) on the Slave: on the Slave assign an IP Address (IPv4) to USB0 within the subnet of the IP Address assigned to USB0 on the Host. Add a Static Route on the Slave pointing to the IP Address of USB0 on the Host as the Default Gateway.

Expanding FS & fix renewal of ssl

May 2020

• Expanding FS to entire disk : only on server 2

Nagios: Core Master & Remote Slave Behind NAT architecture and configuration

May 2020

• The project is for creating a Nagios configuration to be implemented on a cloud Nagios Core (master) with multiple Nagios Slaves in different locations behind a firewall (NAT).
• The cloud master is installed on AWS EC2 and all slaves are installed on a Raspberry Pi 4.
• Slaves are checking the health of services in a remote location, mainly HTTP + PING + DNS.
• The slave nodes are behind a firewall so ideally, the communication will go from the slave -> to the master nagios in the cloud (push, not pull).

NFS server issue on Proxmox

Mar 2020

Really greate work. Thanks!

Since some days we have issues with my nfs backup shares.
We host servers in two datacenters: FRA1 and FRA2. On every datacenter we have a nfs backup server and a proxmox cluster.
Both nfs servers are mounted on each proxmox cluster for local and remote backups.
On FRA1 proxmox cluster I have issues with both NFS servers (FRA1-NFS1 and FRA2-NFS2).
After adding the storage via proxmox UI OR mounting manuelly with “mount -t nfs ….” the nfs mount seems to be working good.
But after some minutes, the share hangs.
I am not longer able to access the shares with “cd /mnt/share” or check then with “df -h”.

route all traffic from one Linux machine through another with separate vpn connections on each

Mar 2020

Pavel’s great! Was able to complete the task and go beyond the original scope with no problem. Got to it and got it done – perfect! He’s definitely a star player.

1) iptable rules to route all traffic from on linux server on the internet to another on the internet
2) iptable rules to the same as #1 but using 2 vdi’s on vmware workstation 15
3) nested vpn tunneling on the Internet:
-all traffic from linux A gets pushed through linux B
-linux B connects to vpn server B to create vpn tunnel B
-linux A connects to vpn server A through vpn tunnel B to created a nested tunnel of linux A’s traffic through vpn tunnel A which is inside of vpn tunnel B
-vpn B creates a tunnel
4) iptable rules to the same as #3 but using 2 vdi’s on vmware workstation 15

Get LetsEncrypt auto-renew SSL certificate working with certbot

Mar 2020

Thank you so much, never seen a task completed so quickly!

I currently have an EC2 server which hosts a WordPress website. We initially installed a LetsEncrypt certificate on there which has now expired.

I would like to renew the certificate and set it up so that it auto-renews using Certbot in the future.

Exim script

Mar 2020

Excellent work on Perl script. I am sure we will use this script for many years to come, so the ROI on the work will be insane. Great stuff and hope to work with you in the future.

Help setting up a Site 2 Site layer 2 VPN

Feb 2020

I have a Beaglebone Black (Debian) in a network with multiple devices. I have another Windows machine in a different network. I need to access the network of the Linux device as if the windows machine lives there. I need to be able to scan for devices and interact with them as the Windows Machine is in the Linux Machine network.

The OpenVPN server needs to be installed in a VPS. The client needs to be installed in the BBB and the other remote computer (Windows or Linux). This setup might need to be used for many tunnels simultaneously so we might need to run many instances of openvpn or you can suggest something different.

Install VPN on Linux server

Feb 2020

The task is to install a VPN on a server where a scraper (already built) is running.

The scraper provides an endpoint which we need to access to control the scraper. The VPN is needed to conceal the origin of the scraper when it accesses the target website.

Even when the VPN is running, the endpoint to access the scraper needs to be accessible by URL.

We have a subscription to NordVPN and will provide you with the creds.

At the moment, the scraper is running on a linux server via Caprover.
To make it clear: at the end of the project, you need to provide a server which is accessible by a URL or IP address which is independent of the VPN and its outbound traffic to the target site is via the VPN.

Squid Proxy Professional Consultation

Feb 2020

Freelancer must develop a special configuration method for contractor that can continue to be used by the contractor on other servers after the job is done.

Freelancer will check a squid proxy server with centos provided by contractor and figure out how contractor can assign unique u/p to every IP binded to each server. This way, every u/p will not be able to be used all the IPs on the server. Instead, it is only one u/p per IP. u/p must be random (ex. n2ibsje:n37bhf2). Also, freelancer must figure out how to extract this same freshly created unique IP u/p list on to a file that it can be copied by contractor to paste on other windows.

After freelancer figures out how this will be done on contractor’s server, freelancer will provide instructions on how the contractor will apply this same method by himself in the future.

Postfix consultant/developer to add extra TLS verification processing to mailflow

Nov 2019

We are looking for a custom postfix module that will perform additional TLS and certificate verification and mail flow processing beyond what is provided in the base Postfix software.

1) Detect recipient’s MTA support of TLS (i.e, TLSv1.2, TLSv1.3) with options for checking certificate authenticity at various levels (i.e., self-signed?, signed?, valid trust? expired?, revoked?, CN/SNI mismatch to HELO and/or domain name of server?)

2) Depending upon a set rule for a given sender domain and/or user, send the queued email to one of several postfix instance for actual delivery. These are some examples of potential policies:
a) Sender allows and MTA provides TLSv1.2+ and any SSL cert then send to postfix-regular
b) Sender requires and MTA provides TLSv1.2+ and a fully authenticated and signed cert then send to postfix-secure
c) Sender requires but MTA does not provide TLSv1.2+ and a signed cert then send to postfix-portal)

Linux scripting to automate creation Samba shares on USB sticks

Sep 2019

I asked Pavel to write a service to run under a specific Ubuntu distribution. He completed the job successfully and in the time schedule I needed. There were some issues that arose with a specific filesystem, and he was very helpful in addressing those as well. I would definitely recommend Pavel to anyone looking for a sysadmin scripting expert, as he has very good knowledge and is also easy to work with. I hope to work with him again in the future, myself.

The goal is to have a collection of scripts to automate the process of mounting a USB drive with ExFAT or NTFS file system on insertion, then creating a SAMBA share with the same name as the drive label. The scripts will also need to handle the removal of the SAMBA share if the drive is removed. Ideally the scripts would run on Ubuntu 18.04.2 LTS.

Steps:

1. Detect USB drive insertion
2. Mount USB drive appropriately (recommended as /mnt/LABEL where LABEL is the drive label)
   -Handle drives with the same names by adding a number afterwards, such as 2 or 3 to indicate the 2nd or 3rd drive with the same name
3. Create the Samba share, using the same name as the LABEL
4. Watch for USB drive removal every 10 seconds, and remove the Samba share if the drive is removed.

Fix Lets Encrypt

Sep 2019

Automatic Lets Encrypt for thousands of domains.

Setting squid with authentification by mysql

Aug 2019

I need to configure Squid on linux and associate it with mysql. The database will be stored for each user:

• login: pass
• IP – external IP (it will also be the IP through which the user will connect)
• port by which it can connect to the proxy
• allowed hosts (json_array), forbidden hosts (json_array) – respectively, the url of the sites to which user are allowed to connect and to which are not. Priority is allowed, forbidden works only if allowed host is empty
• speed – speed limit (Mb / s)
  !!! Important !!! : adding/removing users from DB works without restarting squid. SARG is not needed.

Server Administrator: Fix Latency

Jul 2019

Great freelancer – knows all about linux servers!

I am running a dedicated server on Linux.

We request the following:

• Server health check.
• Monitor all server traffic & activity within 2hrs period.
• Identify and resolve the cause of delay we are experiencing.
• Provide recommendations on server health

System Admin needed for setting up Squid Proxy

Jul 2019

Pavel did a very good job finishing this task. Would hire again 10/10!

Hi there!
I’m currently searching for a bit of help setting up a few proxies.
I currently have a few 4g dongles (Huawei K5160) connected to a Linux machine and I’d like to set them up as proxy using squid. I’ve successfully made one work using a vpn that unlocks ports and it worked fine. Although now I’d like to make a few other ones on the same machine.
You should be able to:

• setup multiple gateways on the linux machine
• balance the load: connect every dongle to a seperate openvpn connection using the certificate I give you
• setup squid proxy for each of them on the same machine using username and pass authentication
• document every step so I can replicate on other machines

Create ipv6 proxy & 6to4 tunneling on linux server

Jul 2019

Absolutely fantastic and excellent freelancer, he created a solution for my requirement in a very simple fashion in which I could configure it without hard knowledge on anything, a simple yet sophisticated solution for my project. He have great communications skills as well and always reply to messages when he’s around.
I would like to advise those that require networking specific jobs to be done to engage this freelancer!

I’m looking for someone who is proficient in linux (Any OS) which would be able to setup IPv6 proxies for me. I’ll have access to 3x /48 IPv6 subnets which has 60,000+ (/64 blocks), each of the /48 IPv6 would be creating 200 proxies (one proxies from one /64) each.

The proxies will need to be using IPv4 IP:PORT to use a tunneling (Using 6to4 method), because the tools and website that I’m using require HTTPS format to be able to use the IPv6 proxies. The IPv4 IPs will only act as a tunnel, but however in whois and etc it should show the IPv6 proxies IP.

Create ZeroTier network that will allow physical devices join it without ZeroTier application.

4.70 Jun 2019

Pavel has completed the given task. Everything works as per request. He is highly experienced. I would recommend him for similar jobs.

I have devices on the network that can not install ZeroTier client, hence they can’t join ZT network. If it is possible i would like to have a ZT virtual machine that acts like a bridge and will connect my physical network with the ZT network.

Devices can join the ZT network without the ZeroTier App. Additional VM, VM-OpenWRT can be created in order to make this happen. This should act like a big L2 network in ‘internet’.

Expert Linux Network Administrator required for VPN and proxy server work

Jun 2019

Excellent network administrator. Did the job quickly and professionally. Will hire again!

The task entails integrating current VPN server setup with a 3rd party CDN peerp-to-peer network using their APIs. The idea is to forward all traffic using sniproxy from our VPN server to the CDN nodes.

Expert knowledge if sniproxy, DNS, DNSMASQ, HTTPS, SSL, TLS, DNAT, IPTables, and VPN is required. You will need to familiarise yourself with the JSON API of the 3rd party CDN together with our VPN server setup which is on CentOS 6.x 64 bit before integrating the two together. You will need to coordinate the integration with network engineers from the CDN provider and they will assist in this process.

Fix Postfix SMTP timeout exceeded error

Jun 2019

Pavel analyzed the issue and suggested a couple pinpoint adjustments which, in combination with our own measures, have successfully resolved the problem.

We have a Debian Linux server with postfix+dovecot which however frequently produces a “SMTP timeout exceeded” error when Thunderbird is trying to send mail on my desktop/laptop. Looking for a sharp Linux sysadmin very familiar with postfix to investigate and fix it.

HAProxy setup for SSL termination with CertBot. Require knowledge of Linux account security.

Jun 2019

Very good Linux knowledge. Work completed on time and within budget without any issues.

We have a non-virtual dedicated Linux server in the UK. We have Apache running and showing a web on HTTP. We also have an SSL certificate provided by CertBot. Now we need a documented process implementing HAProxy configuration so that port 443 is enabled and port 80 is only internal. So we need two things – 1st is HAProxy config setup and 2nd is a documented repeatable process for our other servers.

Need help setting up a 2 node Kubernetes cluster over Wireguard VPN

Feb 2019

Awesome to work with

Background: I have VPS servers setup on AWS. I can do a full and working installation of Kubernetes and I can do a full and working installation of wireguard. The problem is I can’t get them to work together. Whenever I try to route Kubernetes over wireguard and try to join the cluster from the second VPS with the join command it times out and kubelet keeps throwing errors of node “hostname_of_vps” not found. Task: I would like someone with a proper working knowledge of Kubernetes networking to simply look at the setup and let me know what I am doing wrong. We can do this over skype or gotomeeting. Deliverable: A working Kubernetes cluster that properly routes traffic over the Wireguard VPN

WordPress Migration – Ubuntu VPS to another Ubuntu VPS, IP will change but domain name to be same

Jul 2018

Worked with Pavel to migrate a WordPress website currently hosted on Alibaba Cloud to Digital Ocean.

Everything was super smooth sailing – from walking through the process to execution. What I particularly liked was that Pavel let me see the staging site before it went live, and did a re-sync just before full migration. He also set up a reverse proxy on my old VPS to ensure zero downtime. Communication was superb – Pavel has an amazing ability for clarity and distilling complex thought into simple words.

A definite recommendation!
