I just installed 12.04 on a box. I installed openssh-server and started it. On my win7 laptop, I tried to ssh to the ubuntu box with Putty. It timed out. What might be going wrong?

I verified that the sshd process is running on the ubuntu box.

I suppose I should verify that the DNS name that I used from putty on win7 is actually my ubuntu box. I don't remember how to verify the dns name or ip address on the ubuntu box.

I didn't make any changes to sshd_config before starting the server. I rebooted after installing openssh_server.

Can you ping it by hostname? What if you connect using the Ubuntu system's IP address instead of hostname? If I am not mistaken you need wins installed in the Ubuntu system so that Windows can resolve the hostname correctly. – Bruno Pereira♦ May 22 '12 at 15:54
I was given a hostname when I was given the box with Win7 on it. When I installed Ubuntu on it, I didn't think about that when it came to the point in the install of determining the hostname, so it gave it a default name combining my userid with the computer model name. When I do a nslookup of the original name, it finds it. When I do that using the name it ended up with, it says it can't find it. The IP I get from the nslookup of the original name isn't the same as the IP I get from "ifconfig -a" on the Ubuntu box. Pinging both of those IPs say "ping: socket: Operation not permitted". – David M. Karr May 22 '12 at 18:45
Ok, I made some progress. I discovered that "ping" is a restricted operation on Win7, so I had to run the shell (Cygwin) as administrator. I made putty use the ip address that the box thinks it is (from "ifconfig -a"), and that was able to work. It might be worth changing the /etc/hostname value to the basename of the fqhn that I was given, but I can at least move forward with this. I don't know if I really need that "wins" thing you refer to. I also need to set up my keys so that I can ssh over to the box without entering a password, but that's a further question. – David M.
