I'm using Debian Sarge and logged into it remotely using PuTTY and SSH and was in the middle of using aptitude when I got disconnected.

My questions are
a) can I connect back to that session, or am I forced to just kill that session?
b) can those processes just be killed and I can just run aptitude again?

when I do
who
I get
myloginname pts/0 2007-06-29 21:59 (10.1.1.99)
myloginname pts/1 2007-06-30 09:13 (10.1.1.99)

pts/1 looks to be the 2nd remote session I'm logged in with and pts/0 is the one I want to get back to.

running a ps tree with
ps -ejH
(thanks to Google for that one) I get

Afraid you can't. If the connection you're using is not
overly stable it may pay for you to use screen withing your
session, and do your work through that ... in case of an
unexpected event (e.g. a disconnect, or a local reboot)
you can easily re-attach afterwards.
