SSH doesnot work

[Jahrul Alam_1]

Hi
I am running PCQ-Linux7.1 on an HP-NetServer and Redhat 7.0 on another PC. I can not login from one to another. I can login to other machines that are outside my area. It seems that I am not giving permission to logon to my PCs. Can any one help me to troubleshoot this.

Thank you

Hi,

Can you telnet from one to another? What errors do you get when you try to ssh?

Usualy, you get 'Secure connection to refused' which is caused by the fact that the ssh daemon is not running on .

As Eugen says, if you give us a few more details, we can help. The first thing to check is that there are no network issues between the two, that you can ping, telnet, ftp (if you allow those services. And then make sure sshd is running on the server you are connecting to.

Also, if you use the -v option with ssh as you attempt a session, it will give detailed information as to what is going on during the connection. If you post that information to us, we should be able to help.

Adding my $.02 :

Especially under RH 7.0 -- check the config for the ssh service in /etc/xinetd.d directory. There should be a file sshd there, with a line stating the service is allowed. Most remote connections are refused by default (including ssh!).

Hi
It's me again. Actually the problem was caused by the default firewall that comes with PCQLinux7.1 (PCQ and Redhat should be the same). I just disabled the firewall and ssh worked.

Thanks all for the advices.
