This will allow UDP traffic on local machine's port 53 to be forwarded to TCP traffic on local machine's port 6667.Īs you've probably guessed, when a DNS query will be performed on the local machine, e.g. I have project that need to open connection via ssh tunnel, in android I have used jSch library I have succeed to make connection server but I stacked How can I make webview to load url via SSH. You need priviledged access to bind the UDP port 53. Now, we need to do the opposite of what was done above on the local machine. Setup the UDP to TCP forward on your machine This will allow TCP traffic on server's port 6667 to be forwarded to UDP traffic on 192.168.1.1's port 53, and responses to come back. A simple shell pipe would only communicate left process' standard output to right process' standard input. The fifo is necessary to have two-way communications between the two channels. If you want to do DNS forwarding like me, you can take the first nameserver's IP you will find in /etc/nf.īut first, we need to create a fifo. On the server, we open a listener on the TCP port 6667 which will forward data to UDP port 53 of a specified IP. Setup the TCP to UDP forward on the server This will allow TCP connections on the port number 6667 of your local machine to be forwarded to the port number 6667 on through the secure channel. On your local machine (local), connect to the distant machine (server) by SSH, with the additional -L option so that SSH will do TCP port-forwarding: local# ssh -L 6667:localhost:6667 And since most people in this thread would have a SSH server, you already have the tools you need to set up some alternatives. Performing UDP tunneling through an SSH connection Step by step Open a TCP forward port with your SSH connection Ever since SSH Tunnel app stopped working (4.2 or 4.4), SSH tunnels arent the most convenient for Android. This small guide tells you how to send UDP traffic via SSH using tools that come standard (ssh,nc,mkfifo) with most UNIX-like operating systems.
