Greetings, I'm running into a problem with FreeBSD 2.2.6. I have two Class C's on my network and recently a hacker tunnelled into the backbone and masqueraded under an unused IP in my subnet to do spamming. As a result, I opted to bind all my IP addresses - used or not, to one of my servers. So I have about 400 or so IPs bound. When I boot FBSD 2.2.6, everything works, but if I -HUP the nameserver, I get this in the messages log: May 17 14:29:37 mysys named[1266]: starting. named 4.9.6-REL Wed Mar 25 00:29: 44 GMT 1998 jkh@time.cdrom.com:/usr/obj/usr/src/usr.sbin/named May 17 14:29:37 mysys named[1266]: fcntl(dfd, F_DUPFD, 20): Too many open files May 17 14:29:37 mysys last message repeated 15 times The hard limit on open files is set at 360 - this may be inadequate since I may have up to 512 domains mapped to my server. I assume there is a relationship between these two concepts. In scanning the archives on FreeBSD.org, none of the solutions worked for me (regarding setting ulimit ...) - and I didn't try anything regarding compiling the kernel - I'm using the generic compilation right now. What are my options? Do I need to tune the kernel to solve this problem? If so, would someone be so kind as to walk me through this process? Initial examinations showed a value OPEN_MAX, but it simply referenced some header file that I could not find on the system - I haven't done enough research yet to figure out what to do. Any help would be GREATLY appreciated - please direct e-mail to: mp@icorp.net Thanks very much!!
