Help! - DNS seg faults, can't ping non-numeric IPs

Hi,

I'm pretty desperate here...

I've successfully installed Familiar 0.4 (stable) on my iPAQ H3660 and
have got the Buffalo IEEE 802.11b WLAN card working to the point where
I can browse websites wirelessly and ssh into other machines via the
access point / IP masquerading to my net connection.

For some reason, though, the iPAQ DNS is not working correctly. I can
ping a numeric IP fine, but if I try to ping a name (e.g. ping foo or
ping www.yahoo.com), I get an immediate segfault.

Unfortunately, it's not just ping -- the web browser dies if I try to
visit a site for which the IP isn't in /etc/hosts, so it seems to be
something to do with DNS lookups.

I double checked the DNS entries in /etc/resolv.conf and I can ping
the numeric nameserver IPs from the iPAQ fine.

I'm setting all this up for a university research lab and *need* to
get DNS working for our research.

If anyone has experienced this or has any suggestions, I'd be
extremely grateful for any advice you can offer.

Thanks in advance,
