After looking about a bit to try to figure this out, I saw that this is a common problem, and it's usually associated with a problem in doing reverse lookups. It's odd, since it wasn't happening a little while ago on my LAN, but I also noticed it on a Linux box, too. So I added entries for other boxes on the LAN into the /etc/hosts files on the *nix machines and the slowdown went away. However, I don't know how to really fix the problem...are there good troubleshooting tools for this? I did look around a bit on this, but all I found was some code someone had pasted into an email that was archived. It didn't compile, so that was a dead end for me. Anyone with any suggestions? I'm at a loss here. -- Sean LeBlanc, seanleblanc@home.com IM-> Yahoo: seanleblancathome ICQ: 138565743 MSN: seanleblancathome AIM: sleblancathome If you can spend a perfectly useless afternoon in a perfectly useless manner, you have learned how to live. -Lin Yutang (contributed by Chris Johnston) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-newbies" in the body of the message
