Hi managers,

Whilst digging into a network issue, I've noticed that traceroute appears
to be broken on our 5.1A (pk1 and pk2) machines.

If I do a traceroute on one of my wan sites, by IP address, I get a
result, however doing the same thing by name fails:

gs60 # traceroute 192.9.1.120
traceroute to fel34rt001.lynx.co.uk (192.9.1.120): 1-30 hops, 38 byte

gs60 # traceroute feltham

I originally thought that it might be a DNS issue somewhere, however,
running traceroute on the name on Tru64 4.0E and various Linux versions
works fine...

Anybody else seen anything like this ?
