Able to change port number between telnet and ssh?


My company block all ports but 23(telnet) and 21(ftp).
However, i want to use ssh to connect to my web server.

This is some of the settings in /etc/services
Code:
ssh             22/tcp                          # SSH Remote Login Protocol
ssh             22/udp                          # SSH Remote Login Protocol
telnet          23/tcp
telnet          23/udp
I have tried to change ssh to use 23 and telnet to use 22 but failed.

Any idea?
Thanks

Well don't even bother using telnet to your server. Just configure ssh on your server to listen on port 23 instead of 22..

And when you connect from work, it should allow you to pass thru the firewall with no problems. And the services file is just a listing, check your ssh_config in /etc/ssh/ to change the port, restart it, etc.

i found the content in /etc/ssh/ssh_config are all commented out

Code:
# Site-wide defaults for various options

# Host *
#   ForwardAgent no
#   ForwardX11 no
#   RhostsAuthentication no
#   RhostsRSAAuthentication no
#   RSAAuthentication yes
#   PasswordAuthentication yes
#   HostbasedAuthentication no
#   BatchMode no
#   CheckHostIP yes
#   StrictHostKeyChecking ask
#   IdentityFile ~/.ssh/identity
#   IdentityFile ~/.ssh/id_rsa
#   IdentityFile ~/.ssh/id_dsa
#   Port 22
#   Protocol 2,1
#   Cipher 3des
So, i un-comment out Port 22 and change to 23?

Acutally.. sorry, check your sshd_config for the server port settings. I think the ssh_config is when your ssh'ing from that machine to another, etc for default settings. sshd_config should be for the sshd daemon.
And yeah, you should find the port setting there, change to 23 and restart sshd. Then when you connect from work, it should connect using port 23 by default.
