Unknown host error message when trying to ping Internet

[Wil McGilvery]

Ok I tried again and this what I got when a performed an nslookup on for pcisys.net on 216.229.33.250

pcisys.net A 216.229.32.173 
pcisys.net MX 10 mail.pcisys.net 
pcisys.net MX 20 smtp1.pcisys.net 
pcisys.net MX 20 smtp2.pcisys.net 
pcisys.net NS ns1.pcisys.net 
pcisys.net NS ns2.pcisys.net 
pcisys.net NS jerry.pcisys.net 
pcisys.net NS ns1.pcisys.net 
pcisys.net NS ns2.pcisys.net 
pcisys.net NS jerry.pcisys.net 
mail.pcisys.net A 216.229.32.173 
smtp1.pcisys.net A 216.229.32.178 
smtp2.pcisys.net A 216.229.32.146 
ns1.pcisys.net A 216.229.32.170 
ns2.pcisys.net A 216.229.32.166 
jerry.pcisys.net A 207.76.102.251

A reverse lookup gives me.

250.33.229.216.in-addr.arpa PTR marsha-216-229-33-250.pcisys.net 
33.229.216.in-addr.arpa NS ns1.pcisys.net 
33.229.216.in-addr.arpa NS ns2.pcisys.net 
33.229.216.in-addr.arpa NS jerry.pcisys.net 
ns1.pcisys.net A 216.229.32.170 
ns2.pcisys.net A 216.229.32.166 
jerry.pcisys.net A 216.229.32.170

What happens if you try one of the name servers listed above?

I'm guessing that you Suse config is identical to the RH config.

pcisys.net uses 216.229.32.173 as their mail server. Their DNS server is 
216.229.33.250.

If I try to dig or nslookup "pcisys.net" I get a "connection timed out. 
no servers could be reached" message.
