Jack,

No joy on either ping method.  Tried both ping and ping -n.  Tried the 
P-t-P ip addr and the isp website.

mtr -n results in < bash: mtr: command not found >.  It doesn't help to 
su and Find Files doesn't help, so it's likely not installed by default.

Traceroute results in an operation not permitted error.  Results:
traceroute to 206.176.178.93 (206.176.178.93), 30 hops max, 38 byte packets
traceroute: sendto: Operation not permitted
 1 traceroute: wrote 206.176.178.93 38 chars, ret=-1
 207.53.230.163 (207.53.230.163) 1.402 mstraceroute: sendto: Operation 
not permitted
traceroute: wrote 206.176.178.93 38 chars, ret=-1
  1.387 mstraceroute: sendto: Operation not permitted
traceroute: wrote 206.176.178.93 38 chars, ret=-1
  1.503 ms

I also get a lot of < bash: traceroute: command not found > when I've 
already done a chmod +s on /usr/sbin/traceroute and it clearly exists.  
Mandrake 9.1, unlike Redhat 8 has not included traceroute in the menus 
and I have been unable to find a gui traceroute app in the menus.

Just for the record, I'm not clear on what all chmod +s does, but had 
seen the command recommended to change permissions so all users could 
execute the file.  I'm not real happy about the security implications, 
but I need to get this box working on the net.  Hope the firewall is as 
good as Redhat 8's was.

Best regards,

Dan F.
