Subject: GNU screen on Cygwin: Cannot seem to reattach, no matter what I try
Hi Andrew,
Thanks so much for your efforts to port and maintain the GNU screen
program to Cygwin! I used to use screen all the in the pre-GUI days,
and now I use ssh regularly for the occasions I need to run something on
a real win32 or win64 platform. Being able to use screen again would be
great, especially because I routinely get disconnected from one machine
in particular due to a lousy DSL line.
At any rate, although I can run screen just fine, I cannot reattach, no
matter what I do, even when there's been no disconnect and I've simply
manually detached (i.e., Ctrl-A d). The session log below pretty much
says it all.
Note that I move my .screenrc file out of the way to ensure I'm running
with nothing but default settings. Also, you'll notice in the output
from "ps aux" that the "screen" process, once detached, has a tty value
of "?", whereas all the others have a tty number. Other than this,
though, everything works just as one would expect. Processes continue
to run fine under screen even when detached: I simply just cannot
reattach. As you can also see below, doing a "kill -15" on screen
causes it do a proper shutdown and remove the socket file.
Odd, very odd.
Any thoughts?
Finally, please pardon me in advanced if I should have posted this
somewhere instead of emailing you directly. I could not find a forum or
irc or website indicating where to report this / ask for help.
Happy Weekend!
Thanks,
Doug
