ssh connection refused

John McDen — Tue, 16 Apr 2002 18:22:25 GMT

I installed ssh 3.1 on 3 server exactly the same procedure for all.

But I am not able to use ssh to connect to only one of the servers it does not give any error.

I use ssh -l username hostname it prompts me to enter the passwd and then It only says connection refused and comes out.

Any ideas ??

Hi,

Put your ssh host on the other server in hosts.allow file.

HI
Use the "-v" option with ssh to see where it is failing and also check the systlog file for more error information.

Thanks.

Thank you for your help but ...I found out it is becaues of the firewall and need to open the port for it.

But how do I know which port is been used by ssh?

Hi
By default ssh connects on port 22.
You may use lsof to check.

Thanks.

Hi,

Port 22 should do mostly the trick with a default installation.

Is there any command other than installing lsof to find out which port is been used?

Hi,

Do a more /etc/services | grep ssh

Hi John,

Your sshd_config should list the Port used.

John,

While the connection is open,

# netstat |grep ssh

will also show what ports are being used.

Hello John,

everything above is alright and works.
In addition: I think a good idea to check the port is a simple portscan from another system. If you have a linux box for example run "nmap hostname". So you gets the ssh port and also every open port the system is listening. It's important for every admin to know this at all time.
