Well, that's the whole point of "ping". i.e. can one system reach another via ICMP. It is true that using a name instead of an IP address will also force name resolution. However, you may confuse your debugging efforts if there is a problem with name resolution. For example, now that Verisign has screwed with the TLDs your name resolution may not be correct. For example: > traceroute -n verisignissleazyashell.com traceroute to verisignissleazyashell.com (64.94.110.11), 30 hops max, 38 byte packets 1 172.16.128.1 0.696 ms 0.737 ms 0.737 ms ... 15 65.205.32.58 26.454 ms 25.182 ms 20.168 ms 16 64.94.110.11 24.004 ms 19.623 ms 21.954 ms - Paul -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
