Date: Thu, 22 May 1997 17:22:23 -0700 Organization: PrimeLogic Communications Corp. Lines: 33 Message-ID: <michelle-2205971722230001@monalisa.primelogic.com> NNTP-Posting-Host: monalisa.primelogic.com Xref: euryale.cc.adfa.oz.au comp.unix.bsd.freebsd.misc:41461 Today I added the 57th ifconfig line to our server's rc.local file as part of the routine adding of a virtual host. I HUP'ed named and was greeted by a nameserver core dump and complaints of "too many files open." And the nameserver was torched, naturally. I rebooted the entire server, to no avail. Thinking I'd made an error in one of the DNS files, I checked my work carefully and everything looked kosher; the forward, reverse--everything--seemed to be USDA-grade fine. I recompiled the kernel after increasing the number of users from 20 to 50 and rebooted again. No dice. Mutter... Since this state of affairs was precipitated by adding the new virtual it seemed logical to remove the additions that I'd made. On a hunch, I commented out the ifconfig I'd added for the virtual, rebooted, and everything was back to normal. Whew! So have I run up against some limit on the number of IP addresses that can be assigned to the network card? Do I need to change some configuation variable that will increase the number of IP assignments the card can handle? I've looked in the online docs, but haven't found anything that addressed this particular problem. (OTOH, panicky readers sometimes miss things.) I'm running 2.1.5 on a P133 with 32 MB parity RAM. As belt and suspenders, I've just ordered another 32 MB of parity RAM and a second network card. I'm figuring if worse comes to worse, and it's not just a matter of increasing a variable to allow more IP assignments on the first card, the second network card will gain me another 50+ assignments. .\\ichelle -------------------- Michelle Brownsworth System Administrator IMS, Inc.
