Hello all, I have quite a niggling problem with my box. It takes too long to resolve hostname; ranges between 15 to 30 secs. My box serves as a gateway and ipfw machine. Other machines on this network that connects to this machine don't exhibit this particular problem, resolving hostname is pretty quick. I've tried many things; amongst them putting an open firewall just to see if ipfw has anything to do with it; resolving still takes too much time. This machine also serves as a private name server but I doubt that would get in the way as I've disabled the private name server in resolv.conf; only pointing to my ISP name servers. I have another problem which I think is related. Establishing SSH and FTP sessions (the only traffics I tested) from another machine to this machine slow down to a crawl. Only after the establishments did everything ie: transferring files is running smooth. Before this everything is fast, connecting to my private FTP is blazingly fast, I did't even have the time to read the displayed log. Now when I'm doing it I can read and speak out loudly every single word while they are displaying. Even connecting to my ISP FTP server is quicker. Connecting is just too slow for convenience sake. Ditto SSH. I implement DHCP in addition to the name server which use UDP traffic *which* I think, after reading the pertinent man pages, *may* have something to do with UDP timeout or something like that. To change this default attribute, I'd have to edit a kernel variable through sysctl. How do I know the right variable? I'm really at a loss over this. This box serve as my main desktop machine, no longer using Windows and hope to become a convert. __________________________________________________ Do You Yahoo!? Sign up for SBC Yahoo!
