I have experienced a very unusual glich, that I cannot explain. All of a sudden, my network router box became non-complient with internet traffic requests. At first, I thought that it was because I had to restart bind 8 with ndc resart, however, after restarting the service, I still continued to recieve failed server errors. After attempting to ping my provider, I noticed that I came accross this message:ping: sendto: No buffer space available ping: sendto: No buffer space available ping: sendto: No buffer space available ping: sendto: No buffer space available What does this indicate? I am still learning, and do not have significant experience/knowledge with any type of frame buffers, or kernel programming. I can only suspect that maybe my firewalling rules clogged some sort of buffers for the kernel. I don't really know, that is the only thing that I can think of. I have the following firewalling rules setup: 00098 124 8614 allow ip from any to any via lo0 00099 0 0 allow ip from 127.0.0.1 to 127.0.0.1 00100 617 69897 allow tcp from any to any dst-port 22 setup keep-state 00102 0 0 allow udp from 0.0.0.0 to 255.255.255.255 dst-port 67,68 setup keep-state 00103 0 0 allow udp from any to any dst-port 53 via keep-state 00104 685 79362 deny udp from any to any dst-port 137,138,513 00106 0 0 allow udp from any to any dst-port 33435-33524 keep-state 00110 0 0 allow log ip from any to { 192.168.1.0/24 or dst-ip 192.168.2.0/24 } in recv sis0 00200 15704 10185681 divert 8668 ip from any to any via sis0 00300 6267 8810869 queue 1 log ip from any to 192.168.1.0/24 out { xmit xl0 or xmit rl0 } 00301 1715 777060 queue 2 log ip from any to 192.168.2.0/24 out { xmit xl0 or xmit rl0 } 65535 25856 10939503 allow ip from any to any My pipe configs are as follows: 00001: 256.000 Kbit/s 0 ms 50 sl. 0 queues (1 buckets) droptail mask: 0x00 0x00000000/0x0000 -> 0x00000000/0x0000 00002: 128.000 Kbit/s 0 ms 50 sl. 0 queues (1 buckets) droptail mask: 0x00 0x00000000/0x0000 -> 0x00000000/0x0000 q00001: weight 1 pipe 1 50 sl. 4 queues (64 buckets) droptail mask: 0x00 0x00000000/0x0000 -> 0xffffffff/0x0000 BKT Prot ___Source IP/port____ ____Dest.
