Cast of characters:
- Ventris, a win8 machine
- Atticus, a Fedora 14 machine

They are on the same router. Each can ping the other by IP address, each can load web pages and ping the world by hostname. They don't know each other's hostnames, but can ping each other by IP address.

When I run 'ssh uname@atticus' from atticus, I am prompted for a password and log in successfully.

When I run putty from Ventris and point it at atticus' ip address with settings on SSH, I get a timeout. The putty log on ventris exists but is empty. The SSH log on atticus does not gain a new entry (it does show the successful login from atticus).

I used netstat to verify that SSHD on atticus is using port 22 and it is open for both 0.0.0.0:22 and *:22.

I have checked the firewall on atticus and enabled SSH using TCP on port 22. This has also failed with the firewall disabled.

I have checked Windows Firewall (McAfee) on Ventris, and opened port 22 for TCP and UDP traffic.

What do I have to do?

can you show us the outcome of: on the server
and:on the client.

Don't have ssh on the client, using putty.

You can call putty from the command line with the -v (verbose) option. You can also look at the graphical interface's event log. Check for a verbose option.

If cygwin can be installed on Windows 8, you can use it's openssh client, which is the same one Linux uses.

If a live Linux distro will run on the Windows 8 machine (UEFI issues?) you can use the client there.

Logging in to SSH from the same machine as the server won't be very useful.

Client putty log is still empty

Now I am using a Linux VM that is hosted through VMware workstation on Ventris:

[eric@localhost ~]$ ssh 192.168.0.4
ssh: connect to host 192.168.0.4 port 22: Connection refused

Hmmm ... cannot find a log file on the fedora vm.

Needed to set the interface as trusted in the firewall. Solved.

Thanks to all.
