Is there a way to tell an already-running ssh session to forward X11 connections, if you've forgotten to supply -X
on the command line? If so, how?

Not really; you'll want to disconnect and reconnect.
If you want to forward X sessions most of the time, then consider a bash alias such as:
alias ssh="ssh -X"
You can also set it permanently in ~/.ssh/config
by setting ForwardX11 yes
.
I was afraid of that. I tried setting up port forwardings from within ssh by using the escape character
~
after a newline, but I had no way to set up the Xauthority stuff. The main reason I haven't made such an alias until now is that every time I usessh -X
on Mac OS X, it delays for several seconds while it starts Xquartz at the beginning of the session. Since I don't usually need X I prefer not to forward it all the time. – echristopherson – 2012-07-21T22:57:16.027
