To create a SOCKS5 server on a Linux machine using the terminal, you can use dante-server, a popular option for setting up a SOCKS proxy. Here’s how to do it:

Step 1: Install Dante Server

First, you need to install Dante. Use the following command to install it:

bash

Copy code

sudo apt update sudo apt install dante-server

Step 2: Configure Dante Server

The configuration file for Dante is usually located at /etc/danted.conf. You need to edit it to configure your SOCKS5 server.

bash

Copy code

sudo nano /etc/danted.conf

Here is a sample configuration for a SOCKS5 server:

logoutput: /var/log/danted.log

# Internal network interface
internal: eth0 port = 1080

# External network interface (use the IP of your server)
external: eth0

method: username none

clientmethod: none
user.notprivileged: nobody

# Allow connections from any IP (you can restrict this to specific IPs)
client pass {
    from: 0.0.0.0/0 to: 0.0.0.0/0
    log: connect disconnect error
}

# Allow the SOCKS5 traffic
socks pass {
    from: 0.0.0.0/0 to: 0.0.0.0/0
    log: connect disconnect error
}
  • The internal directive specifies the interface and port the server will listen on (1080 in this example).
  • The external directive specifies the external network interface.
  • The method is set to username none to allow connections without authentication (you can change this to add a username/password requirement).
  • The socks pass section allows the traffic to pass through.

Step 3: Start the Dante Server

After saving the configuration, start the Dante server:

bash

Copy code

sudo systemctl restart danted

To ensure it starts on boot, enable the service:

bash

Copy code

sudo systemctl enable danted

Step 4: Verify the SOCKS5 Server is Running

You can check if the server is running by using netstat:

bash

Copy code

sudo netstat -tuln | grep 1080

You should see something like:

plaintext

Copy code

tcp 0 0 0.0.0.0:1080 0.0.0.0:* LISTEN

This confirms that the SOCKS5 server is listening on port 1080.

Step 5: Connect to the SOCKS5 Server

Now you can configure any SOCKS5-compatible client to connect to your server using the server’s IP address and port 1080.

Does it support udp?

ChatGPT said:

ChatGPT

Yes, Dante does support UDP traffic, which is a requirement for many applications like gaming or VoIP that rely on UDP for communication. However, setting up UDP support in Dante requires additional configuration.

To enable UDP support for your SOCKS5 server with Dante, you need to modify the danted.conf configuration file and make sure that both TCP and UDP traffic are allowed.

Step 1: Modify the danted.conf File

Open the configuration file for editing:

bash

Copy code

sudo nano /etc/danted.conf

Then, update your configuration to explicitly allow both TCP and UDP traffic. Below is an example:

logoutput: /var/log/danted.log
 
# Internal network interface
internal: eth0 port = 1080
 
# External network interface (use the IP of your server)
external: eth0
 
method: username none
 
clientmethod: none
user.notprivileged: nobody
 
# Allow connections from any IP (you can restrict this to specific IPs)
client pass {
    from: 0.0.0.0/0 to: 0.0.0.0/0
    log: connect disconnect error
}
 
# Allow both TCP and UDP SOCKS5 traffic
socks pass {
    from: 0.0.0.0/0 to: 0.0.0.0/0
    protocol: tcp udp
    log: connect disconnect error
}

rez: use this:

 
# Internal network interface
internal: enp5s0 port = 1080
 
# External network interface (use the IP of your server)
external: enp5s0
 
method: username none
 
clientmethod: none
user.notprivileged: nobody
 
# Allow connections from any IP (you can restrict this to specific IPs)
client pass {
    from: 0.0.0.0/0 to: 0.0.0.0/0
    log: connect disconnect error
}
 
# Allow both TCP and UDP SOCKS5 traffic
socks pass {
    from: 0.0.0.0/0 to: 0.0.0.0/0
    protocol: tcp udp
    log: connect disconnect error
}

rez: find problem! this pc (like mozila and curl) can’t see proxy!

}
 
# Allow both TCP and UDP SOCKS5 traffic
socks pass {
    from: 0.0.0.0/0 to: 0.0.0.0/0
    protocol: tcp udp
    log: connect disconnect error
}

Step 2: Restart Dante Server

After making the changes, restart the Dante server:

bash

Copy code

sudo systemctl restart danted

Step 3: Verify UDP Support

To confirm that UDP traffic is being handled correctly, you can use tools like netstat to check the open UDP port:

bash

Copy code

sudo netstat -uln | grep 1080

You should see a line indicating that port 1080 is open for UDP as well as TCP.

Step 4: Test UDP Functionality

To test that UDP traffic is working, you can try using a client that supports both TCP and UDP through SOCKS5 (such as a compatible web browser or application). Alternatively, you can use tools like nc (netcat) to test UDP connectivity.

listen to dante for resived data

ChatGPT said:

ChatGPT

To monitor the data received by your Dante SOCKS5 server (or any network service), you can use various tools such as tcpdump or wireshark to capture the network traffic on the relevant port (e.g., port 1080 for Dante).

Here’s how you can use tcpdump to listen to the data received by Dante on port 1080:

Step 1: Install tcpdump

If you don’t have tcpdump installed, you can install it using the following command:

bash

Copy code

sudo apt install tcpdump

Step 2: Capture Traffic on Port 1080 (Dante SOCKS5)

To capture both TCP and UDP traffic on port 1080 (the default port for Dante), you can use the following tcpdump command:

bash

Copy code

sudo tcpdump -i eth0 port 1080

  • -i eth0 specifies the network interface to capture traffic on (replace eth0 with the actual interface you’re using, such as enp3s0 if needed).
  • port 1080 tells tcpdump to capture traffic on port 1080 (the default port for SOCKS5 servers).

Step 3: Capture Both TCP and UDP

By default, tcpdump will capture both TCP and UDP traffic. If you want to be more specific or filter by just UDP or TCP traffic, you can use:

  • For UDP:

    bash

    Copy code

    sudo tcpdump -i eth0 udp port 1080

  • For TCP:

    bash

    Copy code

    sudo tcpdump -i eth0 tcp port 1080

Step 4: Analyze the Output

Once you run the command, you’ll start seeing the raw packet data. The output will show packets captured in real-time, including source and destination IP addresses, ports, and protocol details.

For example, you might see something like:

plaintext

Copy code

15:24:32.576039 IP 192.168.1.100.54321 > 192.168.1.1.1080: UDP, length 64 15:24:32.576112 IP 192.168.1.1.1080 > 192.168.1.100.54321: UDP, length 64

This will show the source and destination IPs and ports, and the length of the packets being sent.

Step 5: Stop the Capture

To stop capturing the packets, press Ctrl+C in the terminal.

Optional: Saving Captured Data to a File

If you want to save the captured traffic to a file for later analysis, use the -w option:

bash

Copy code

sudo tcpdump -i eth0 port 1080 -w dante_traffic.pcap

You can then open the dante_traffic.pcap file with a tool like Wireshark to analyze the data more easily.

Let me know if you need any further explanation or additional help with setting this up!

telnet

ChatGPT said:

ChatGPT

Telnet is a simple command-line tool used to connect to remote servers and devices via the Telnet protocol, typically used for testing network services or troubleshooting.

To use telnet to connect to a SOCKS5 server like Dante, you can follow these steps:

Step 1: Install telnet

If you don’t have telnet installed on your system, you can install it using:

bash

Copy code

sudo apt install telnet

Step 2: Use telnet to Connect to the Dante Server

Assuming your Dante server is running on port 1080 (the default SOCKS5 port), you can use telnet to connect to the server:

bash

Copy code

telnet <server_ip> 1080

Replace <server_ip> with the IP address of the machine where the Dante SOCKS5 server is running.

For example:

bash

Copy code

telnet 192.168.1.100 1080

Step 3: Testing the Connection

Once connected, if the server is up and running correctly, you will see a blank screen or a response indicating that the connection has been established. However, Telnet by itself doesn’t support the SOCKS protocol, so it won’t allow you to make real SOCKS5 requests.

Step 4: Using Telnet for Debugging SOCKS5 Traffic

While telnet can’t be used to make SOCKS5 requests, you can still use it to check if the port is open and if the server is responding. If the connection fails or hangs, this could indicate an issue with the server or firewall.

Step 5: Telnet for Testing Other Ports

You can use telnet to test other services and ports (like HTTP, SMTP, or custom services). For example, to test a web server:

bash

Copy code

telnet example.com 80

This will connect to port 80 (HTTP) on example.com, and you can then manually send HTTP requests to the server.

Example of Sending an HTTP Request Using Telnet:

After connecting to a web server on port 80, you can manually type an HTTP request like this:

plaintext

Copy code

GET / HTTP/1.1 Host: example.com

Then, press Enter twice to send the request.

Step 6: Exit Telnet

To exit the telnet session, type:

bash

Copy code

quit
