I tried to connect to a server with ssh, but it failed. I tried UseDNS no, update OpenSSH with MacPorts. But it didn't work.

Using user@ip -v I get the following output

OpenSSH_5.9p1, OpenSSL 0.9.8r 8 Feb 2011

My MAC OS version is 10.8.2.

Does anyone have a idea ?

Thanks.

Is ssh-agent running on your machine? You can check with ps aux | grep ssh-agent –  Tonin Mar 11 '13 at 22:23

From the log trace and from your screenshot one can see that ssh-agent is not running. That is what is causing your ssh session to hang and not respond.

There might be multiple reasons for your ssh-agent not running, including misconfiguration or conflict between different versions of ssh binaries installed (Apple original one, macports or brew installed). The best and easier, unless you're sure what you're doing and you have a reason to do it, is to stick with Apple's original.

Try to revert to a backup installation or re-install OSX properly.

This other question on ServerFault (and my answer) may help you further.

Thanks, @Tonin. But , Is there any way restore my mac os x without loss my personal data ? –  cyildirim Mar 16 '13 at 17:17
    
@cyildirim That only depends on the backup that you have. Make a backup of your data, of your personal directory, then re-install the system. –  Tonin Mar 18 '13 at 17:23
    
I re-installed system with backup time machine and problem fixed. –  cyildirim Mar 21 '13 at 23:04
