Trying to create a socks (-D) ssh tunnel - Linux box to Linux box (both centos):
sshd running on remote side ok.
From local machine we do / see this:
ssh -D 1080
[email protected].
[email protected]'s password:
bind: Cannot assign requested address
(where 8.8.8.8 is really my server's IP and 'user' is my real username)
I am logged into the remote side in this terminal-window. I can verify that the local port was unused prior to this
command, and then used by an ssh process, after the
command, via:
netstat -lnp | grep 1080
So, unlike most googled-responses with this error, the problem would not seem to be the loopback interface assignment. If I try to use this tunnel with a mail client, the local-side permits the attempt (no 'proxy-failed' error), but no data / reply is returned.
On the remote side, I do have "PermitTunnel yes" in my sshd_config (though 'yes' should be the default, anyway).
Ideas or Clues?
Here is the relevant debug-output
OpenSSH_5.3p1, OpenSSL 1.0.0-fips 29 Mar 2010

Other clue: If I run a Virtual Box on the client running Windows, open a tunnel with putty in that box, that tunnel, to the same remote server, works.
