ssh change port
 

hello

how do i change the port that ssh uses?

i have changed the port number in the ssh_config and sshd_config
but i still does not work.

I am not sure, but did you restart the ssh, usually changes do not take place, until you send the HUP signal to the proccess and make it reread its config files, or until you stop it and restart it again.

hrmm

how would i restart it?

i typed in:

sshd restart

and it gives me:

Extra argument restart.

Try:
service sshd restart

when i do service sshd restart it says:

-bash: service: command not found

redhat:
slackware:

oh it worked

but now i get some kind of an error:

cipher_encrypt: bad plaintext length 337

is that something i should worry about?

hrmmm i still cant get ssh working

any ideas on what

cipher_encrypt: bad plaintext length 337

means?

anyone? anyone? anyone?

(echos) lol

At the console type "cat -A /etc/ssh/sshd_config". If you see ^M (aka Control M) or a lot of space then it has $. I could be that the ssh does not like like lines. You have to edit it. I suggest using vi but you can use any text editor. vi is the standard text editor for LINUX because it does not take up much room and it consumes less memory.

i couldnt find a ^M or alot of spaces before a $

but here is what cat says:

I was having this problem
http://www.linuxquestions.org/questi...d.php?t=510959

and now have the issue referenced in this thread!!!

This thread is very old, but I'm going to :cry:

Solved the Issue.... FINALLY!!!!

Got the solution from http://www.linuxforums.org/forum/sus...nfig-file.html

Check if your server's keys are OK. If not, re-create them.

Thank you. All is now well :D
