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

Matt,

  I suppose I can help(I _was_ a DNS guy), but I need more description.

1. Do you use DHCP/pump?
2. If not, what did you wrote in resolv.conf. Please send it as-is
   if possible.
3. you say ping fails -- how? host not found or just blocks up?
4. If you can, use tcpdump to see if(and how) the resolver works.
   you may set 'port = 53 and host = [handheld's ip address]' to
   see what's going on.
5. Try the same resolv.conf on another host and see what's happen.
