Hi Sam,
The app tries a DNS lookup for "user-pc". The domain gets
appended from
/etc/resolv.conf
dhclient does update /etc/resolv.conf from dhcp, but it's been doing that
for quite a while. That hasn't changed, and your real issue is the slow DNS
response.
Doing an strace should tell you which DNS server gets queried, but it's
probably your router acting as a DNS forwarder; and the real issue becomes
why your router takes several seconds to return a DNS response.
Actually, for looking up my own hostname no DNS query should be needed at all.
I've just checked - even in case it really is a configuration issue
within the network - Windows7 just copes fine with it
So I wonder, shouldn't the DNS code in glibc simply detect the lookup
in this case is localhost (as Windows DNS implementation does
obiously)?
