From: Kenny McCormack on 8 Jul 2010 08:58 I put in my /etc/hosts file: 192.168.99.99 myhost Then I do: ping myhost and it works. But when I do: telnet myhost it says: myhost: No address associated with nodename Why? How to fix? Tested repeatedly over the course of about 10 minutes (because I know there is some latency in OSX where if you edit the Unix-y configuration files, the OS doesn't always pick up on it right away). In all tests, the ping worked but the telnet did not. Note: telnetting directly to 192.168.99.99 works fine. -- > No, I haven't, that's why I'm asking questions.

Makes me wonder if there are some "strange" characters in the /etc/hosts file. Carefully retyping the line might be a worthwhile experiment. > > Then I do: ping myhost > > and it works. ?But when I do: telnet myhost > > it says: myhost: No address associated with nodename Nodename? I would have expected to get "hostname" out of a telnet error message. Or perhaps "Unknown host" In HP-UX land at least a "nodename" is associated with UUCP not TCP/IP. To verify that telnet and ping are, or are not, following the same name resolution order you might try taking a system call trace of each. rick jones -- the road to hell is paved with business decisions... these opinions are mine, all mine; HP might not want them anyway... :) feel free to post, OR email to rick.jones2 in hp.com but NOT BOTH...
