[HECnet] getting the bridge working on OpenBSD

[Brian Hechinger]

Yeah, I think I had an older copy. Pulled the latest down and it built cleanly other than the MAX redefinition warning and the "openbsd thinks you're a moron for using strcpy()" warning.

All appears well as Sampsa can talk to HECnet via a bridge to me tunneled over OpenVPN. Ugly, but functional. :)

Brian, could you verify that you have the latest version? I did some work to try and get rid of warnings a while back, and even though I'm sure some issues might be because of 64 bit issues, I would have expected some of the warnings you reported to have been fixed already...
