[Bug 579737] [NEW] OpenVPN client connect hangs on PUSH_REQUEST

[Waldo2k2]

Public bug reported:

Binary package hint: openvpn

A client connecting to an OpenVPN server running Lucid hangs on
PUSH_REQUEST. Same server config works on Karmic.

My server config does not contain any 'push' directives. If I add the
tcp-nodelay macro to my server config, the 'push "socket-flags
TCP_NODELAY"' that it sends the client prevents it from hanging and the
connection completes. The tcp-nodelay option fails on the Windows
clients I tested it with, but merely passing the PUSH fixes the
connection hang.

I haven't tested any other push directives to see if they have the same
effect.

Current package version: 2.1.0-1ubuntu1 (lucid)
Working package version: 2.1~rc19-1ubuntu2 (karmic)
