Use lots of "-L" command line options :-?

It depends on what you mean by "dynamically". Some implementations
(eg, PuTTY, OpenSSH, possibly others) have a "dynamic forward" option
which implements a SOCKS server in the SSH client, so if you application
understands SOCKS (or can be made to, eg "socksify" or "runsocks") then
it can use an SSH tunnel pretty much transparently.

Alternatively, you could use something like OpenSSH's EscapeChar and
add local forwardings at run time (eg "[CR]~C -L lport:remhost:rport").

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
