Good afternoon Tom, Is it possible to ssh into a Linux box from a Windows machine through a VPN tunnel? For example if i wanted to access our private LAN from the Internet using VPN how would i be able to use SSH to add more security during the authentication process? Thank you, James

You may do anything over a tunnel what you will usually do over an unencrypted session, as tunneling "simply" encapsulates TCP/IP packets - after having encrypted them. What''s inside the packet may be a telnet session, an rlogin, ftp command or an ssh authentication. hth, Robert Kehl
Slightly off topic can netbios work through a vpn tunnel as well? So that I may access samba shares from the remote vpn as if I was at the home lan?

Netbios requires UDP; I don''t think you can push those through an SSH tunnel.

Plenty of stuff on Google about tunneling Netbios through SSH.. One thing to keep in mind while your reading is, is this unicast netbios or broadcast netbios..

Yes, you may use the TCP/UDP/ICMP connections you want over/in/under/with a tunnel. Tunneling a connection is no more than encrypting the traffic and wrapping it with another (UDP, I believe) header. It doesn''t matter what''s inside. You may safely use Tunnels to stretch your LAN from Los Angeles to new York, if you like, including NetBIOS.

Ack. I can''t read. My apologies for providing an answer to an unasked question.

That''s pretty cool. I''ll try to get netbios working through the vpn tunnel. Maybe I can even print a document in the home lan from the remote vpn (kind a like a secure fax).
