ssh:connection timed out [closed]

Question

I am trying the following command on ubuntu

ssh host@xx.xx.xxx.xxx

and I get the following error:

ssh: connect to host xx.xx.xxx.xxx port 22: Connection timed out

so, I tried the following:

telnet xx.xx.xxx.xxx 22xx

and I got the following message:

Trying xx.xx.xxx.xxx...
Connected to xx.xx.xxx.xxx.
Escape character is '^]'.
SSH-2.0-OpenSSH_5.5
Connection closed by foreign host.

Can anyone help me understand what the problem is and how I can fix it.

I would be helpful if you gave more detail in your question. For example, what version of Ubuntu and ssh are you running on both the client and server? As for troubleshooting, you might first want to check to make sure that a port is open on the server, and next that the package openssh-server is installed on the server.

Make sure that your SSH server process is listening on port 22.

Check the file /etc/ssh/sshd_config and check if it has the line 'Port 22'

If the port number is different, then you need to try to connect to that port

$ ssh xx.xx.xxx.xxx -p port_number

If that doesn't work then it could be a firewall issue.

try to telnet to that port and verify you can connect to it.
