Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-isp@freebsd.org X-Loop: FreeBSD.org Precedence: bulk This is strange... Has anyone else seen this happen? Last night one of the machines I admin, spock.edmweb.com [204.244.190.2] went down, or so it seemed. I (inside the LAN) was unable to ping Spock, and another person outside was also unable to ping that machine. I went to the console today fully expecting I would have to reboot the machine, but when I got there everything was fine... It had never actually gone down. uptime showed it had never crashed and/or rebooted. All of the processes were still running. The log files showed nothing out of the ordinary, and syslog had placed it's mark messages at the proper intervals. It appears as though the machine lost it's network connection (ethernet) then got it back... netstat -in shows a few hundred 'Oerrors' which seems to confirm that the network connection was lost. The machine is a 16-meg Pentium 100 with Asus Triton motherboard and SCSI-II hard drive on an Adaptec 2940. The ethernet card is an SMC EtherPower 10/100 in 10 mbps (standard ethernet) mode. There is a Cyclades Cyclom 8yo installed, which is not really being used yet. Running FreeBSD 2.1.0-RELEASE with the /sys/netinet/in_rmx.c from -stable to correct the Proxy ARP bug. The only thing the machine was really doing at the time was hosting the Chatnet IRC bots. The bots disappeared from IRC, and when the connection came back they were still gone from IRC, but their proccesses were still running. I would guess maybe this is an ARP problem, but I don't know. I've never seen it happen before. Has anyone else seen this? ===================================================================== | Steve Reid - SysAdmin & Pres, EDM Web (http://www.edmweb.com/) | | Email: steve@edmweb.com Home Page: http://www.edmweb.com/steve/ | | PGP (2048/9F317269) Fingerprint: 11C89D1CD67287E68C09EC52443F8830 | | -- Disclaimer: JMHO, YMMV, TANSTAAFL, IANAL. -- | ===================================================================:)
