SSH Problem - Can't login using Hostname, can login using ip address

jqweezy · 01-26-2009, 12:10 PM

Hello All,

I am having a problem logging into my remote gentoo (2.6.23) linux machine using my hostname from my Windows XP machine using cygwin. I can login using my ip address, but not the hostname.

This works:
$ ssh me@xxx.xxx.xx.xxx

This does NOT work:
$ ssh me@my_hostname
ssh: connect to host my_hostname port 22: Connection refused

I have verified that my hostname is indeed "my_hostname" on my linux machine by using the "hostname" command. Any ideas on what my problem could be? I look foward to any feedback you may have.

Regards,
JQ

It doesn't matter what your hostname is set to on the server. It does matter how the name gets resolved from the client.

So, from the client side (Windows?), post the results of: nslookup your_hostname

If it's not resolving to the correct IP address, there is your issue.

Your server has to have a fully qualified name before it is going to be accessible only by a name if you are outside your own subnet.

you can add it in the hosts file
xxx.xxx.xxx.xxx domain.com

Thanks for your reply. Your right, I get Non-existent domain when I do an nslookup my_hostname.

How would i go about resolving to the correct IP?

I am on the same subnet.

How would i go about resolving to the correct IP?

get a real domain name with DNS entries
or
Add it in the hosts file
xxx.xxx.xxx.xxx domain.com

@jqweezy: The wikipedia hosts file article describes where to find this on Windows systems.

That would probably be the way to go, unless you've registered this hostname/IP address with DNS already. (Or intend to do so.)

Thanks alot guys, adding it to my hosts file worked. Thanks anomie, repo, and pentode for your responses.
