Can't unset close-on-exec flags on Ubuntu 12, ssh 5.9p1 #1
Description
My system is Ubuntu 12 LTS. that is using OpenSSH_5.9p1 ( Debian-5ubuntu1, OpenSSL 1.0.1 14 Mar 2012 ). I tried this
solo -port=1234 ssh remote -fN
to create a stable tunnel to the remote server. Unfortunately, when ssh is executed, it seems to ignore / modify the variable $^F, so that
solo -port=1234 ssh remote -fN # will execute ssh
solo -port=1234 ssh remote -fN # will execute ssh
will launch two different ssh connections / processes on my system (the expected result should be one)
This problem happens only with ssh. If I use ping 0 instead,
solo -port=1235 ping 0 # will execute ping
solo -port=1235 ping 0 # wil exit
the program solo seems to work well.
I don't encounter this issue with ssh on Ubuntu 10 LTS and Ubuntu 11.
