If you are using SOCKS proxy, you will also need to set it accordingly. As you will finish making changes, your system will update them automatically within no time. Proxy on Firefox Browser. By Default you are provided with the Firefox browser on CentOS Linux so you can configure its proxy settings manually. You can update your proxy settings. I need a socks 5 proxy server that can run on centos. This would use a block of IP's so that client X with IP Address zzz connects tomy proxy server with ip xxx and then to remote host with ip yyy.
socks5
Socks5 is a proxy protocol, which plays an intermediary role between the front-end machine and the server machine that uses TCP / IP protocol to communicate, so that the front-end machine in the Intranet can access the server in the Internet network, or make the communication more secure. Socks5 server simulates the behavior of a front end by forwarding the request from the front end to the real target server. Here, the front-end and Socks5 also communicate through TCP / IP protocol. The front-end sends the request to the real server to the Socks5 server, and then the Socks5 server forwards the request to the real server.
If your machine has a legal Internet IP address, or if you can freely communicate with any host on the Internet by dialing the modem on your own machine, you usually don't need to care about Socks5 protocol. Socks5 protocol is useful for the machine in the internal network, which needs to access the outside through some machines in the network that can connect with the external Internet. In the process of sending the communication request to the real server, the Socks5 server does not change the request packet itself. After the Socks5 server receives the response from the real server, it also forwards it to the front end. Therefore, Socks5 protocol is a kind of proxy protocol, which can adapt to all kinds of application layer protocols based on TCP / IP. Although it can't understand the internal structure of the data it forwards, it can faithfully forward the communication package and complete the function that the protocol should complete.
Different from Socks5 protocol, HTTP proxy is carried out through HTTP protocol. The HTTP proxy server software understands the internal structure of the communication package, and it also needs to modify and transform the communication program in the process of forwarding. Different from HTTP proxy protocol, Socks5 is actually a transport layer proxy protocol. We can imagine that if every specific application layer protocol has to design the corresponding proxy protocol expression, a specific proxy server can not support so many new emerging protocols in any case. Therefore, it can be said that the emergence of Socks5 eases the difficult situation that a variety of specific protocols need to specially design proxy protocols. However, not all software using TCP / IP application protocol can communicate unconditionally through the Socks5 server, and the front-end software itself is required to have the Socks5 interface to use the Socks5 proxy server.

- In this post we are going to set up a Socks5 Proxy server using SS5 on CentOS 7. The two most common types of proxies are HTTP (Hyper Text Transfer Protocol) and (Secure Sockets 5). The SOCKS4 and SOCKS4a protocols do not support UDP or authentication. The current SOCKS5 and HTTP proxies differ in the following ways.
Installation configuration
1. Install SOCKS 5
1.1 installation dependent development library
The code is as follows:
1.2 installing SOCKS 5
The code is as follows:
# tar -xzvf ss5-3.8.9-8.tar.gz
# cd ss5-3.8.9
# ./configure
# make
# make install
2. SOCKS 5 configuration
2.1 modify configuration file
The code is as follows:
auth 0.0.0.0/0 – –
Change to
The code is as follows: Diablo 2 update 1.13 d.
auth 0.0.0.0/0 – upermit – 0.0.0.0/0 – 0.0.0.0/0 – – – – –
Change to
The code is as follows:
3. Add socket 5 users
The code is as follows:
##User password
ttlsa 123456
4. Start socket 5
The code is as follows:
doneting ss5…
By default, the SS5 file does not have permission to execute. If you feel that it is troublesome to use sh to start, you can use the following method:
The code is as follows:
#Chkconfig — add SS5 / / optional
#Chkconfig SS5 on / / optional
# service ss5 start
5. Check whether it is started
The code is as follows:
tcp 0 0 0.0.0.0:1080 0.0.0.0:* LISTEN 14262/ss5
Default port 1080
6. Test Socks5
Install proxifier. By default, all requests go to Socks5. Open Baidu and enter IP. You can see the following results: our operation and maintenance survival time( ttlsa.com )IP address of
7. Common mistakes
7.1 lack of PAM
The code is as follows:
# yum -y install pam-devel
8. End
Have you successfully installed Socks5? I haven't turned off Socks5 yet. You can take the account and password in this chapter for a test.
The following post describes how to set up dante-server (danted / sockd), a SOCKS5 proxy server, with user/password authentication. It should work on Debian and Ubuntu.
On Ubuntu 14.04 You will have to compile dante yourself. Maybe other Ubuntu versions as well. Click here for the Ubuntu 14.04 how-to.
– it lets anyone (as in any IP address) connect
Windows unpacker. – it requires user and password of a systemuser (e.g. root)
Here is how I did it on Linux Debian 6 (Squeeze) minimal x86, at first I will explain it without authentication and then tell you what to modify to add authentication:
. to update your system and to install the text editor nano.
Then install dante-server:
It will output an error message in the end:
So let's configure it. The configuration file is at:
Rename it and make a new one:
Now copy this and insert it into PuTTY with a right click:
Now you have to change the following lines depending on your system.
venet0:0 is the network adapter/interface which can be (and very likely is) different on your system.
To check the name use the command:
Which will output the names. In my opinion it should have been venet0 for me, but it didn't work so just try all of them if the proxy server refuses connection.
Another very typical name would be eth0.
The IP address needs to be changed to the EXTERNAL IP of your server (the one you could also access an apache web server with from your computer):
To save with the nano editor hold CTRL+X and confirm the changes with 'y'.
Now make sure dante-server is stopped and start it again:
Try to connect with your browser. We haven't set an authentication yet so a web browser is an easy way to check if it is working. If it says 'connection refused' you entered wrong information in the config file.
If it opens the website you are trying to access, congrats! 😛 Now let's implement authentication which is really easy. Simply change the following line:
to
Now you should be able to identify yourself with the user specified in the following line:
Yes, it is the system user. If you specify root you have to log in with the username 'root' and the password of your server/vps that you use for SSH access.
//EDIT: Technically authentication had been enabled before,too except now you just disabled the access for non-verified users.
Microsoft key generator. You might have to start the server as root for authentication to work (or with sudo).

Restart danted/dante-server:

. and check if the authentication works. I checked it with the P2P file sharing program 'Ares' which returns 'Test passed' if it works. And that's it, hope this tutorial helped someone. 🙂
