OK, so I’ve upgraded my laptop to Fedora 15, and want to restore the backup, but I can’t ssh into it. Here’s what happens:
[simberg@linux-host ~]$ ping 192.168.0.105

So I can ping it, but it won’t connect. I’ve installed opensshd on the laptop, I’ve enabled it, and the firewall has port 22 open. I can also ssh into it from a terminal on the machine (e.g., ssh localhost or ssh 192.168.0.105), but not from another computer on the network. Any ideas?
Don’t you have to generate a security token and pair the keys between the two machines? It seems to me when i used Ubuntu that I could just run SCP, provide the username and password on the remote computer, and it would generate a temporary key on its own. Then, launch the copy command straight away.
To verify the firewall isn’t an issue, disable it entirely until everything is working.
I disabled it to test. Same result. I reenabled because I really don’t think it’s a good idea to have a diabled firewall on a machine hooked up to the Internet.
OK, I guess I had to apply the changes. Now it seems to work, with port 22 enabled.
