Hi folks! Ok, I'm at my wits end here and I'm hoping someone can give me some pointers in the right direction. I am running RedHat 7.2 as a PDC, with Postfix for my SMTP server, and UW's Imap server for POP. Here's what I'm observing:
>From the local network...When I try to SSH into the linux box, connect via POP, send mail, or log into the domain, it frequently takes up at least 30 seconds to establish a connection. >From the outside world...When I try to SSH into the linux box, connect via POP, or send mail, its a snap (just a few seconds at most) to connect to the box. It almost seems as if something on the box is trying to do reverse dns lookups on private IPs. I've been searching in vain to try and figure out what controls this and how to either a) configure it to not do reverse dns on private ips, or b) turn off reverse dns altogether. I've searched all the specific application conf files for Postfix, Samba, SSH, etc, and can't find anything. The fact that this slowness is affecting all of these programs seems to suggest that the problem is occurring at some lower level that they all use. Unfortunately, I'm at a loss as to where to look next. Does anyone have any suggestions here? tia, Christian ---------------------------------------------- Christian Cryder [[EMAIL PROTECTED]] Internet Architect, ATMReports.com Barracuda - http://barracuda.enhydra.org ---------------------------------------------- "What a great time to be a(n employed) Geek" _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
