Its supposed to be the default.  It doesn't work because I left the
return out of the if in the loop when I rewrote it to go with
the new readipifc interface.  The code should look like:

void
readipinterfaces(void)
{
	Ipifc *nifc;
	Iplifc *lifc;

	ipifcs = readipifc(mntpt, ipifcs, -1);
	for(nifc = ipifcs; nifc; nifc = nifc->next)
		for(lifc = nifc->lifc; lifc; lifc = lifc->next)
			if(ipcmp(lifc->ip, IPnoaddr) != 0){
				ipmove(ipa, lifc->ip);
				sprint(ipaddr, "%I", ipa);
				if(debug)
					syslog(0, "dns", "ipaddr is %s\n", ipaddr);
				return;
			}
	ipmove(ipa, IPnoaddr);
}

Thanks, I'm an idiot.

Hi,

Readipinterfaces() in ndb/cs.c sets ipa to IPnoaddr (even though it's
able to locate a real ip address in the loops before).

The problem with this is that when you start cs on a machine without
an ethernet interface and a loopback ip interface, cs no longer
sets the system name.

I just commented out the "ipmove(ipa, IPnoaddr)" and it works like a
charm.  Is there anything I'm missing, i.e.  any reason for that line
of code to be there?

thanks
