Hello list, I need some help, I don't have too much experience by FreeBSD, my only knowledge is just managing Postfix + IMGate that Len built for me.
So far I've been very satisfied with everything, I've been using it since February 2003. During these 10 months I just needed a couple of times to reboot the machine, once because we changed it's IP address, the others when we have to move servers in our data center. But since a couple of days something very strange is happening: - The machine becomes unreachable, no one is able to ping it - My whole network starts receiving some very heavy traffic & collisions from the IMGate box, making almost all my machines in our LAN totally unreachable or at least with very heavy packet lost until the IMGate box is rebooted - If I login directly into the IMGate box while this is happening everything looks normal, besides that I can't also reach other hosts, but there aren't any strange processes, heavy use, etc. As I said after I reboot everything goes back to normal for a couple of hours or more than a day, some days I have to reboot it more than once, like today: 3 times so far. So this is happening at any time. Do you have any ideas on what's happening? Has something like this happened to any of you? What I should do to avoid this from happening? Could this be some kind of attack or maybe I have a faulty NIC? If it's the NIC the strange thing is that behaves well for several days sometimes, but lately is happening more often. My box details: Intel Pentium III 700Mhz 768MB RAM 20GB Hard Disk 3Com 3c905B-TX NIC FreeBSD 4.7 Postfix 2.0.16 (snapshot) The partitions have light use: Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ad0s1a 395238 37898 325722 10% / /dev/ad0s3e 5155508 328844 4414224 7% /usr /dev/ad0s4e 12666974 1354134 10299484 12% /var procfs 4 4 0 100% /proc Any help it's very appreciated.
