Bug#454784: openssh-client: Concurrent connections fail on the control socket creation race
Package: openssh-client
Version: 1:4.6p1-5
Severity: normal
I use "ControlMaster auto" in my .ssh/config, which usually works fine,
except for two problems:
- the main one is already mentioned in some other bugreport (failure to
connect if there's a stale control socket).
- the other one is that if I start 2 ssh clients concurrently, the second
one will establish the commuincation fine and will then exit with an error
because it was not able to create the control socket (because that socket
was created by the first client).
The easiest solution is probably to let ssh ignore the error rather than exit. The better solution would be to create the socket before establishing the connection so the second ssh would connect via the first one.
