[Bug 1578] New: Remote port forwarding with a listen port of '0' only works for root user bz #1003
https://bugzilla.mindrot.org/show_bug.cgi?id=1578
Summary: Remote port forwarding with a listen port of '0'
only
works for root user bz #1003
Product: Portable OpenSSH
Version: 5.2p1
Platform: Other
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: sshd
AssignedTo: unassigned-bugs at mindrot.org
ReportedBy: gavin at emf.net
Created an attachment (id=1618)
--> (http://bugzilla.mindrot.org/attachment.cgi?id=1618)
Change made to line 1123 of serverloop.c
In 5.2p1 only root can login using remote forwarding with port 0 and
get a port dynamically assigned. Non root users get an error like this:
debug1: Remote: Server has disabled port forwarding.
debug1: remote forward failure for: listen 0, connect localhost:8080
Warning: remote port forwarding failed for listen port 0
debug1: All remote forwarding requests processed
when running:
ssh -v -R 0:localhost:8080 -N gavin at xxxxx.com
whereas the port is dynamically assigned as expected when the user is
root
ssh -v -R 0:localhost:8080 -N root at xxxxx.com
debug1: remote forward success for: listen 0, connect localhost:80
Allocated port 49189 for remote forward to localhost:80
debug1: All remote forwarding requests processed
I fixed this in line 1123 serverloop.c. Hopefully this doesn't break
something important.
Gavin
