-----BEGIN PGP SIGNED MESSAGE----- Ok guys I need some help here with a freaky networking problem. I'm running FreeBSD 4.2-RELEASE on a P120 with 64 MB of RAM and roughly 6 GB of online storage. The machine runs great from the console however after a few days of uptime the network connection goes all to hell. I can restart the machine and things are back to normal and it works smoothly on both the console and through SSH and FTP. During the slowdown I can check top to see if any processes are running wild and I don't see anything that is abnormal. And as I said anything done from the console works great no matter what so I think this indicates that it is not a process going out of control. As far as services go I'm running ProFTPd and SSHd as well as sendmail. I'm however noticing some odd connections when I do a dmesg....you can see a clipping below. Why is my DNS server always trying to connect to my server using UDP? Anyway there you go. I thank you for your help in advance. > Connection attempt to UDP 164.106.194.12:2472 from 164.106.192.1:53 > Connection attempt to TCP 164.106.194.12:53 from 61.218.24.2:2561 > Connection attempt to TCP 164.106.194.12:53 from 210.72.122.1:3847 > Connection attempt to TCP 164.106.194.12:53 from 203.242.151.1:3178 > arp: 164.106.194.11 moved from 00:00:1d:21:8a:0b to > 00:50:2a:a8:f8:00 on tx0 Connection attempt to UDP > 164.106.194.12:2478 from 164.106.192.1:53 Connection attempt to TCP > 164.106.194.12:113 from 128.173.35.190:3587 arp: 164.106.194.11 > moved from 00:50:2a:a8:f8:00 to 00:00:1d:21:8a:0b on tx0 arp: > 164.106.194.11 moved from 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on > tx0 arp: 164.106.194.11 moved from 00:50:2a:a8:f8:00 to > 00:00:1d:21:8a:0b on tx0 arp: 164.106.194.11 moved from > 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on tx0 arp: 164.106.194.11 > moved from 00:50:2a:a8:f8:00 to 00:00:1d:21:8a:0b on tx0 arp: > 164.106.194.11 moved from 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on > tx0 arp: 164.106.194.11 moved from 00:50:2a:a8:f8:00 to > 00:00:1d:21:8a:0b on tx0 arp: 164.106.194.11 moved from > 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on tx0 arp: 164.106.194.11 > moved from 00:50:2a:a8:f8:00 to 00:00:1d:21:8a:0b on tx0 arp: > 164.106.194.11 moved from 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on > tx0 arp: 164.106.194.11 moved from 00:50:2a:a8:f8:00 to > 00:00:1d:21:8a:0b on tx0 arp: 164.106.194.11 moved from > 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on tx0 arp: 164.106.194.11 > moved from 00:50:2a:a8:f8:00 to 00:00:1d:21:8a:0b on tx0 arp: > 164.106.194.11 moved from 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on > tx0 arp: 164.106.194.11 moved from 00:50:2a:a8:f8:00 to > 00:00:1d:21:8a:0b on tx0 arp: 164.106.194.11 moved from > 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on tx0 arp: 164.106.194.11 > moved from 00:50:2a:a8:f8:00 to 00:00:1d:21:8a:0b on tx0 arp: > 164.106.194.11 moved from 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on > tx0 arp: 164.106.194.11 moved from 00:50:2a:a8:f8:00 to > 00:00:1d:21:8a:0b on tx0 arp: 164.106.194.11 moved from > 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on tx0 arp: 164.106.194.11 > moved from 00:50:2a:a8:f8:00 to 00:00:1d:21:8a:0b on tx0 arp: > 164.106.194.11 moved from 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on > tx0 arp: 164.106.194.11 moved from 00:50:2a:a8:f8:00 to > 00:00:1d:21:8a:0b on tx0 arp: 164.106.194.11 moved from > 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on tx0 arp: 164.106.194.11 > moved from 00:50:2a:a8:f8:00 to 00:00:1d:21:8a:0b on tx0 arp: > 164.106.194.11 moved from 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on > tx0 arp: 164.106.194.11 moved from 00:50:2a:a8:f8:00 to > 00:00:1d:21:8a:0b on tx0 arp: 164.106.194.11 moved from > 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on tx0 Connection attempt to > UDP 164.106.194.12:2519 from 164.106.192.1:53 Connection attempt to > UDP 164.106.194.12:2533 from 164.106.192.1:53 Connection attempt to > UDP 164.106.194.12:2537 from 164.106.192.1:53 arp: 164.106.194.11 > moved from 00:50:2a:a8:f8:00 to 00:00:1d:21:8a:0b on tx0 arp: > 164.106.194.11 moved from 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on > tx0 arp: 164.106.194.11 moved from 00:50:2a:a8:f8:00 to > 00:00:1d:21:8a:0b on tx0 arp: 164.106.194.11 moved from > 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on tx0 arp: 164.106.194.11 > moved from 00:50:2a:a8:f8:00 to 00:00:1d:21:8a:0b on tx0 arp: > 164.106.194.11 moved from 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on > tx0 arp: 164.106.194.11 moved from 00:50:2a:a8:f8:00 to > 00:00:1d:21:8a:0b on tx0 arp: 164.106.194.11 moved from > 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on tx0 stray irq 7 > arp: 164.106.194.11 moved from 00:50:2a:a8:f8:00 to > 00:00:1d:21:8a:0b on tx0 arp: 164.106.194.11 moved from > 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on tx0 arp: 164.106.194.11 > moved from 00:50:2a:a8:f8:00 to 00:00:1d:21:8a:0b on tx0 arp: > 164.106.194.11 moved from 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on > tx0 arp: 164.106.194.11 moved from 00:50:2a:a8:f8:00 to > 00:00:1d:21:8a:0b on tx0 arp: 164.106.194.11 moved from > 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on tx0 arp: 164.106.194.11 > moved from 00:50:2a:a8:f8:00 to 00:00:1d:21:8a:0b on tx0 arp: > 164.106.194.11 moved from 00:00:1d:21:8a:0b to 00:50:2a:a8:f8:00 on > tx0 stray irq 7 > too many stray irq 7's;
