Re: New NIC Has Problems
Hi, I have an Ultra2 with 2 NICs connected to 2 different networks and it routes without any problem. The 2 NICs have the same MAC address, because Linux doesn't recognise the local-mac-address? switch. To be able to route with ipchains, you first need to configure the box as a router by setting /proc/sys/net/ipv4/ip_forward to 1. Once you have done that, you still need to enable the FORWARD rule in ipchains. I can't remember the exact syntax, but you should be able to find it on the net. Good luck and I hope this helps, Bertrand. --- Irvin Probst <[EMAIL PROTECTED]> wrote: > On Thu, 2003-08-14 at 06:27, Patrick Morris wrote: > > "why would ifconfig show the same MAC addresses > unless there was a problem?" > > > > This is standard Sun behavior, and can be changed > from the OBP (ok prompt) using > > "setenv local-mac-address? true" > > Or if you have a hme NIC you can specify it when > loading the module, eg: > modprobe sunhme macaddr=0x8,0x0,0x20,0x42,0x69,0x12 > > -- > Irvin Probst > There are 10 types of people in the world... those > who understand binary > and those who don't. > > > -- > To UNSUBSCRIBE, email to > [EMAIL PROTECTED] > with a subject of "unsubscribe".

That's normal, see Steven post regarding this issue, but as long as the two NICs are not on the same subnet this does not hurt. Are you sure that /proc/sys/net/ipv4/ip_forward is set to 1 ? -- Irvin Probst There are 10 types of people in the world... those who understand binary and those who don't.
RE: New NIC Has Problems
>From what I have been reading, on the internet, it seems that the local-mac-address does not work under Linux. I need to know if that is still correct or has it changed. Because this SPARC is being used to route I do not understand how the same MAC will not cause a problem, yet some of the E-Mails I have read said that if the two cards are on different logical networks there will be no problem. Since I need ipchains to route to the two NICs, I do not understand how the same MAC address could work. Could some one explain that to me.

Re: New NIC Has Problems
I don't have the complete solution, but this information should point you in the right direction if someone else doesn't supply the exact command before you get the answer. The issue is that the OBP process sets the MAC address of all nics to the same value by default. In the OBP documentation, there is a setting you can set to prevent that from happening.

New NIC Has Problems
I have a SPARC 5 that I just got a SBUS 100T NIC for. I installed it and it seems to work because I get no errors about the second NIC. I am using PMFirewall to configure the ipchains on the box. The box does not seem to route. When I do an ifconfig I see both interfaces, eth0 and eth1. The two interfaces have the same MAC address. How do I tell if both NICs are working and how why would ifconfig show the same MAC addresses unless there was a problem? David Demland
