Here are 10 basic steps, if you have all the correct access on your shell then you would have no problem. This is for the latest psybnc file: psyBNC2.3.2-4.tar.gz
1) wget
http://www.psychoid.lam3rz.de/psyBNC2.3.2-4.tar.gz
(If you don't have the wget command, download this file onto your PC, and upload it onto your shell in the root dir home/usr/username.)
2) tar zxvf psyBNC2.3.2-4.tar.gz
3) ./configure
4) make
(Then after it is installed onto your shell)
5) cd psybnc
6) pico psybnc.conf (or download it onto your hard disk, open it with notepad)
7) Change the default port number from '31337' to any from the range of 1024-65535 you would desire.
Save the file via pico, or upload and overwrite it.
9) Run the psybnc by: ./psybnc
10) Connect to your shell server, /server hostname:port
