[TUHS] UNIX and relatives and SSH

Sorry for my previous aborted message. I'm using webmail which is an alien sort of thing to me. What I wanted to say is that you may as well let them 'telnet' to the PDP11-2.11BSD through SSH. I mean, you may have the PDP behind a firewall with all ports blocked, and another machine (linux, *bsd, whatever) with SSH open. Then all that would be needed is that your friend uses an SSH tunnel to the telnet port of the PDP. For instance, let's say you open an account for your friend on the intermediate machine: s/he may use this machine to forward one of his local ports (say 2300) to port 23 on the PDP11 system (say pdp11-2bsd.example.net) as ssh -L 2300:pdp11-2bsd.example.net:23 hop.example.net This would forward his local port 2300 to port 23 of pdp11-2bsd.example.net, using the host hop.example.net as an intermediate SSH step. Then all that your friend needs to do is issue a telnet localhost 2300 and that would connect him to the telnet port of the PDP11 using SSH. If s/he uses windows, most SSH clients have a port forwarding tool that makes introducing this information very easy. So, to sumamrize: - you open an account on an intermediate host that has SSH - your friend creates a tunnel from his own computer to the PDP using the intermediate host with his user/pswd. - your friend telnets his/her own local computer at the chosen port All communications will be encrypted between his/her computer and the intermediate host, and go in the clear between the intermediate host and the PDP. If the intermediate host is behind a firewall, then that would be no problem. j ______________________________________________ Renovamos el Correo Yahoo!
