Hi all, I ran into an interesting problem yesterday when running 3.0-19990201-STABLE installation. While trying to perform a FTP install, my card seemed unable to respond to ip traffic. The card was set up in PNP mode (0x300, IRQ 10 detected in dmesg). The card seemed to setup correctly, assigned 192.168.0.32 as an IP, then tried to pass some ip traffic through it. I ended up with about 95% of the packets dropped, but the link light remained on, and some of the packets were getting through at their normal speed (0.6 ms). After fighting with it for a while, I went in with the 3Com config program, hard assigned these values into the card, diabled PNP, and restarted. This led to yet another interesting behavior, in this case the card seemed unable to talk through the firewall, the ping times were fine, but the ftp wouldn't work, in either active of passive mode. I have at least ten other machines behind the firewall and they were all working just fine. Finally I gave up and switched it over to public IPs, after which time it worked fine (public IP's are on a standard hub, private IPs are on a switch). Anyone have an explanation here? I can't figure it out. I also noticed that there were a number of kernel messages where IPs were switching between numerous MAC addresses (don't have the exact numbers, but I also noticed the same thing happening on the firewall). For example: On 3.0-STABLE box: ... /kernel: 192.168.0.1 moved from 00:...:8f to 00:...:8e ... /kernel: 192.168.0.1 moved from 00:...:8e to 00:...:8c ... /kernel: 192.168.0.1 moved from 00:...:8c to 00:...:8f On Firewall (3.0-STABLE): ... /kernel: 192.168.0.32 moved from 00:...:4b to 00:...:4d Anyone got any ideas? The firewall server is running 3.0 CVSup'ed probably 2 weeks ago.
