Actually what I am thinking it may be APIC support problem. I rebuild my kernel to use single cpu without APIC support, my device and 3c905 both work fine. they don't work for SMP kernel (APIC is by default enabled) Then I configured my uni-processor kernel to enable the APIC support, my device won't work with the 3c905, just exactly same as it behaves in the SMP kernel. With 2.2 I also had this without APIC. I have been flooded with interrupts which have been intended for the Cyclone card (3c905B 100BaseTX), and exited the ISR quickly after querying the interrupt register of my Matchmaker board without any ACKing, but the Cyclone never got these interrupts anymore. But is doesn't seem to be a 3c905 based problem, as I have 11: 95772726 XT-PIC es1371, eth0, eth1 in /proc/interrupts where eth0 and eth1 are both Cyclones. Even the vga card has IRQ 11 assigned.

APIC problem or 3com 3c590 driver problem in smp kernel 2.4.x
Hi, all, I have one pci device in my dell optiplex gx300 dual pIII box. when this device in a certain pci slot, it shares the same IRQ with the on mother board 3com NIC(3c905) (irq=5). when I run the kernel smp-2.4.x, my PCI device can not receive any interrupt while the /proc/interrupts shows that 3c905 receives over million of interrupts and number grows very fast. then I moved my pci device to another pci slot, now, 3c905's irq=5, my device's irq=0xb, my device behaves normal, the interrupt number for 3c905 also looks normal. I also tried to use a uni-processor kernel without APIC support enabled, my pci device shares irq with 3c905, but works fine. It looks more like APIC support problem. but it also may be 3c905 driver's ISR's problem. Anyone who owns the code has any idea about this? Thanks in advance. Alex -- Feng Xian _o) .~.

The driver for my pci device, I have the SA_SHIRQ set. Actually what I am thinking it may be APIC support problem.

That's a bit strange as one of the first things done in 3c59x ISR is: if ((status IntLatch) == 0) goto handler_exit; /* No interrupt: shared IRQs can cause this */ with which the driver detects if the interrupt was generated by the card.

RE: Linux NAT questions- (kernel upgrade??)
i think iptables is a new feature in kernel 2.4.x(and you have to build it in the kernel or as module). you can use ipchains if you are running kernel with lower version, 2.2.something.

I have a genuine network, say 1.1.1.x, and my Linux host is on it, as 1.1.1.252 (eth0). I also have a second network at the back of the Linux box, 192.168.200.x, and a web server on that network, 192.168.200.2. The Linux address is 192.168.200.1 on eth1. What I want to do is make the web server appear on the 1.1.1.x network as 1.1.1.160. I have done this before with Firewall-1 on NT, by putting an arp entry for 1.1.1.160 to point to the Linux machine eth0. The packets get redirected into the Linux machine, then translated, and then routed out of eth1. The benefit is that there is no routing change to the 1.1.1.x network, and the Linux box isn't even seen as a router. I would appreciate any help with this. Any command to do this? Chee Tong This isn't really a kernel question. I think you'd better ask it on some linux network list/newsgroup. But here's an answer anyway You could add 1.1.1.160 to eth0: ip addr add 1.1.1.160 dev eth0 and then use NAT to redirect these to the webserver: iptables -t nat -A PREROUTING -p tcp --dst 1.1.1.160 -i eth1 -j DNAT --to-destination 192.168.200.2 This should work, AFAIK, but i didn't try it myself. You could also try to use the arp command (see 'man arp'), but i don't know exactly how that works. Good luck!
