Hi,
Thanks for your guys help!
It looks like a naming service issue.
[b]ping 192.168.0.10[/b] and [b]ping -n -s 192.168.0.10[/b] work well without
any delay, but [b]ping -s 192.168.0.10[/b] got stuck.
Maybe the 192.168.0.10 was temporarily added before I test, so Solaris always
tries to figure out who uses this address. It is pretty strange to note that,
[b]ping 192.168.0.10[/b] has no delay, but 1 second repeated ping "ping -s"
always has delay in the beginning.
