The firewires are all inactive. The only difference from ipconfig is
that the cluster head has a ppp0 defined because of a VPN I'm using.
I tried -mac btl_tcp_if_exclude ppp0, but that didn't work.

So I logged off the VPN, and now ifconfig -a on the cluster head does
not show the ppp0. However, everything is now fixed: I can use
mpiexec without the MCA declaration.
