I read of this
ProxyCommand ssh b nc -q 1 b 22
within an ssh config file
I am curious what "b 22" does?
I know that -q 1 is about exiting "-q seconds after EOF is detected, wait the specified number of seconds and then quit." and one can probably do without it.
Also, out of interest, where is a man page online that has -q? I see
http://linux.die.net/man/1/nc
doesn't have it
