Re: sftp not connecting.

Instaead of sftp, if you ssh to this server, can you get connected without any problems ?

Re: sftp not connecting.

I think to run sftp for network ports you need 21 AND 115 open. Check to see if they are.
Along with Mel's comments, if you can't run ssh, see you can run scp and copy the files over that way (which I'd prefer over sftp).

i you have this line :

Subsystem sftp /usr/libexec/openssh/sftp-server

Re: sftp not connecting.

permissions are already correct:

drwxr-xr-x 2 root root 4096 May 22 2006 libexec

Re: sftp not connecting.

fizan,

When performing your test ssh connection to localhost, it would also be helpful to enable debugging for the server-side in addition to the client-side (/usr/sbin/sshd -ddd) - you may also want to turn up the debug level on the client-side too, to get more detail whilst troubleshooting (ssh -vvv localhost)

Hope this helps.
