why "netstat -a" hangs...

[ogniemi]

although DNS resolvs affected IPs which seems hangs "netstat -a"???

the IP/names are resolvable in/by DNS.
the /etc/netsvc.conf has "hosts = local, bind4"
the /etc/resolv.conf is set properly (host/nslookup works as expected)

when I add the host/IP causing hanging of netstat to /etc/hosts then "netstat -a" doesn't hang.

any idea why DNS is not enough for proper working of netstat?

thx,!

Perhaps your nameserver only provides a non-authoritative answer for those addresses and suggests further querying on other (unreachable? slow? whatever?) nameservers.

Also I've seen netstat -a delaying some output lines because of sockets listening on broadcast addresses (e.g. NTP), which cannot be found in /etc/hosts or DNS...

HTH,
