Mac ssh tunnel manager tutorial7/6/2023 What step one does is to establish a tunnel through a ssh connection. If the ssh command you use is too long, you can encapsulate it in a small shell script, or use the ~/.ssh/config file (see man ssh_config for the details) and put specific LocalForward directives in for a given hostname. It's actually simpler though for incoming mail to use IMAPS (secure IMAP) as that's has encryption built in and most mailers support it these days.

This will tunnel connections for the web proxy (you'll have to configure your browser to use localhost ports 80 for regular and SSL-encrypted browsing, respectively), outgoing (smtp) mail, and incoming mail on both IMAP and POP3 to the correct host (in Charlottesville substitute aoc, gb, or tuc as appropriate). This does entail some extra work though, and should only be tried if you know what you're doing and can change the configuration of your mail client! Something like this would work: ( Experts only!) If we tunnel one service, why not others? It's relatively easy to extend that ssh command to add some extra tunnels so that you can connect directly to mail services.
