[distcc] distccd only compiling locally

Sun Dec 13 15:26:26 MST 2009

Hi,

I'm having an issue similar to http://www.mail-archive.com/distcc@lists.samba.org/msg03593.html
In my case distccd is doing all the compiling locally and none on the remote machine.

To test, I'd setup distccd on two machines, A and B, having 2 x dual-core core Opterons and 4 gigs of ECC RAM.
They're running Slackware Linux 13, stock kernel 2.6.29.6-smp i686.
These machines don't do anything else and have dual 1000M ethernet links.

The jobs are run locally, and the compilation was successful, it's just not distributed.
I don't see any jobs on the remote machine and the CPUs are idle.
What's up with that?
