Hi all,
Is it possible to run tmux under Windows using cygwin? Can anyone point
to a how-to on this or any other relevant information?
Nope, not until Cgywin supports passing file descriptors over a Unix
domain socket.
Hi everyone. First post here.
I'm resurrecting this old thread to see if I can get a little more
information about what the problem is with Cygwin. Nicholas, can you
please tell me anything more about this problem, or point me to any mailing
list discussions of it? I looked around and found a mention of yours that
tmux uses the SCM_RIGHTS OOB data mechanism to pass a file descriptor. Is
that the issue?
Yes, we need to be able to pass the stdin, stdout, stderr file
descriptors from each tmux client to the tmux server. This happens by
sending control messages (of type SOL_SOCKET/SCM_RIGHTS) over the tmux
Unix domain socket.
See http://www.openbsd.org/cgi-bin/man.cgi?query=CMSG_DATA. The CMSG API
is also described in SUS and RFC2292.
Working around this lack in tmux is not trivial, we would need to wrap a
lot of stuff to pass the data around ourselves over a couple of
sockets. Possible but very messy.
Some other programs seem to be in the same boat for at least some of
their features, for example Dovecot.
The reason I ask is that I'd like to engage the Cygwin developers and see
if there's any possibility of working through or around this. If there is
I'd be willing to package tmux for Cygwin. libevent builds in Cygwin with
At one point OpenSSH needed this for some feature and there was a
discussion about maybe how to add it but I gather it is not easy and
whatever happened it has not so far happened.
no problem.
Thanks,
Andrew.
