[Bug 3133] New: Dynamically Assigned Ports for DynamicForward and LocalForward
https://bugzilla.mindrot.org/show_bug.cgi?id=3133
Bug ID: 3133
Summary: Dynamically Assigned Ports for DynamicForward and
LocalForward
Product: Portable OpenSSH
Version: 8.2p1
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P5
Component: ssh
Assignee: unassigned-bugs at mindrot.org
Reporter: cmirchandani at msn.com
The RemoteForward option allows a port to be dynamically assigned if 0
is entered as the port number. It would be helpful if the ssh client
could do the same for DynamicForwards and LocalForwards.

+1. RemoteForward has had the ability to dynamically allocate the
listening port since bz#1003, but LocalForward doesn't currently
support it.
I'd like to be able to do something like:
$ ssh -MNf remote
$ port=$(ssh -O forward -L 0:localhost:1234 remote)
$ client localhost:$port
without having to do a "localport=$(( 32000 + $RANDOM )); ssh -L
$localport:localhost:1234 && break" loop, or something similar.
