Good, don't give up :)

It seems that it fails to use Avahi to find the ZeroConf service.  Do
you have the avahi-daemon installed? Any special conditions like SELinux
which could prohibit program operation? Is IPv6 support installed? Any
additional information here would help us to reproduce the error.

You could try to use "strace" when starting mandos-client without
- --connect and send us the output; this might give us a hint of where the
problem lies.  What user are you running mandos-client as?  Not that
this should make any difference; for us it works both as root and non-root.

"--connect" with mandos-client bypasses Avahi/ZeroConf completely. Here
I have no idea why it doesn't work, and I haven't been able to reproduce
it.  Any manual installations of GnuTLS/libgcrypt11?

That sounds seriously weird.

Could you please also send the complete server debug output as well as
the server configuration?
