(In reply to Damien Miller from comment #2)
 I don't see a compelling reason to change this.
Becuase it's a better an cleaner way of handling it, for those people
who do want to use shared locations, and likely is trivial or doesn't
require much work?

Apart from that,... same argumentation with the bug #2311 - since
closing that one is a mistake, closing this one is either.

Like the manual now recommends, don't use shared directories for mux
sockets.

If you do use shared directories and are happy to accept that
particular risk, then it is up to you to make the path unique. You can
add %u to the path explicitly very easily.

I don't see a compelling reason to change this.

(Sorry, hit enter too fast)


This issue is from [0], see also bug #2311.


If a shared location like /tmp would be used for the ControlPath
setting of ssh, the following issues may arise:

1) %C (the hash hover local host, remote user, hostname, port) alone,
may lead to collisions, since local host, remote user, hostname, port
are not alone to generate unique names.
The local user name should be added to %C.

2) The manpage section which tells people which data they should use at
least to prevent collisions should be adapted as well, to also include
%u (i.e. the local user name).


Cheers,
Chris.
