[Bug 391874] [NEW] “dynamic” application-level port forwarding non-functional

Thu Jun 25 01:06:59 BST 2009

Public bug reported:

Ubuntu 9.04; openssh-client 1:5.1p1-5ubuntu1

What I expected to happen:

$ ssh -ND 127.0.0.1:1080 host

creates a SOCKS proxy listening on 127.0.0.1 that relays traffic through
the host.

What happened instead

No love. Logs below.
