Hi.
I was playing around a bit and noticed the following behaviour which
doesn't seem to match the documentation (which basically says the first
time an option is set, that value is used).
Having the following ~/.ssh/config:
Host foo bar
HostName %h.example.org
Host foo.example.org
User root
ControlMaster auto
ControlPersist 1h
Host bar.example.org
User root
ControlMaster auto
ControlPersist 1h
Host *
ControlPath ~/.ssh/control-mux/%l_%r@%h:%p
ControlPersist 1s
...the following happens when one logs in to foo or bar (without the
domain).
1) Apparently, using HostName works in a way so that ssh_config is
parsed again with the new name, because a socket is actually created.
This behaviour seems to be undocumented, i.e. from the documentation I'd
have expected that logging in to "foo" wouldn't cause the config from
"foo.example.org" be used.
I'd write a patch, but since all my previous pull requests improving the
docs have been ignored even after asking back several times I don't
bother.
2) Since ControlMaster=auto applies to just "foo" or "bar", one would
expect that ControlPersist=1h does so as well. But it doesn't (the 1s is
taken).
As soon as I exit, the mux process quits (after 1s) and the socket gets
removed.
That's not how I'd interpret how inheritance works from the manpage...
is it a bug?
ControlPath in turn is taken up again correctly.
Cheers,
Chris.
