Unable to SSH to Server with terminal, Putty Works (SOLVED)

Hi all,

I am unable to ssh to a remote server from the terminal, when I try with Putty it works,  heres the output of ssh -v

OpenSSH_6.3, OpenSSL 1.0.1e 11 Feb 2013

I suspect it has something to do with my terminal?  I am using xfce terminal

Update:
so following advice from other forum members, I am marking this as solved.  The situation resulted from me installing a new router and this router blocked SSH connections, I search on stackoverflow and tried this fix at

http://stackoverflow.com/questions/2247 … i-does-not

I applied the setting to /etc/ssh/ssh_config and it started working again.

Please use code tags.  You can see how to do this by clicking on the "BBCode" link below (which will open in a new tab).

Re: Unable to SSH to Server with terminal, Putty Works (SOLVED)

I helped another member off-line with this a couple days ago.  He also had:

debug1: Roaming not allowed by server

The problem is at the client end.  Either you are being blocked at the Ethernet Bridge/Firewall (likely) or you have a permissions problem with your keys in ~/.ssh (the directory and everything in it needs to belong to your user)

What is the environment from which you are trying to work?  Home network? Cafe? School? Work?

Re: Unable to SSH to Server with terminal, Putty Works (SOLVED)

Hmm I'm trying from home, unlikely it's a firewall issue cause I can ssh in with putty, and everything in .ssh folder is chmod to 600.  What is this roaming not allowed by server?

Found out it was my router blocking, I had to put this in my ssh_config
