Multi Happy Meal Ethernet problem

Multi Happy Meal Ethernet problem

[Flavio Pescuma]

Hi,


This is the way I want to connect my Ultra 30



192.168.1.0    ______________________________
                                                |
                                                | eth0
                                        Ultra
30-----eth2--------------------!----------------! 192.168.3.1
                                                | eth1
                                                |
192.168.2.1  ---------------------------

Each card is connected to a different network.  The Kernel recognizes
all cards connected,  I've configured route for each network, but
neither eth1 nor eth2 receive any traffic.  I've also tried to set eth0
down eth1 down and configure eth2 alone to eth0 old network
(192.168.1.0) and try to reach the same hosts that I could reach with
etho, but didn´t work.  It looks like even though eth1 and 2 are seeing
by the driver, this cant receive or forward packets through them.

Thanks for your suggestions,

Flavio

Multi Happy Meal Ethernet problem

[Flavio Pescuma]

Hi,

I have just succeeded to install ultralinux-1.1.9 on a Ultra 30
machine.  This machine has three Happy Meal ethernet cards, the problem
I have is that eth0 works fine but the other two doesn't.  The module
seems to work perfectly because it recognize the three of them,  but
neither eth1 nor eth2 receive any traffic at all.

Thanks in advance,

Flavio

Hm....I've got an Ultra 1 that has 2 HME's and they work fine - I'm using
that machine as a router at the moment, actually.....it's working quite
well.

Flavio,

Are you trying to put all three (or four) Ethernet connections on that 
Ultra30 in the same domain?  If not, disregard the following.

As far as I know, each ethernet connection from a given system must be in a 
different domain, otherwise one default connection (usually eth0) always 
defines that system's interface.

Um.... I'm failing to see how that makes any sense at all.  If he's got
individual IPs for each of the cards, and he's got a route for each of
them, then they _should_ all work.  DNS doesn't have anything to do
with that.

	Unless PCI suns are any different, the hardware MAC address for
ethernet cards on sparc depends on the machine hostid. So, if you have 3
cards, they all share a common MAC address. It's OK if they are not in the
same _ethernet_ domain (not the same DNS domain).

Miguel

Oh, right, ethernet domain.  Still, this shouldn't have that effect unless
you're doing something thats requiring arp to function correctly.  Normal
TCP/IP stuff is still going to depend on routing tables.  

Although, this brings up a reasonable point -- if they're all on the same
IP subnet, then you may very well only notice one of them getting traffic.

hmm.. domain isnt the right word. Each Network connection of a host (not only
ethernet) must be in a different subnet. There is one exception:
If you want to bridge between 2 segments, you must have the network
devices in the same subnet. But I dont think Flavio wants to do that :-).

But another question to Flavio: are all interfaces recognized by the
machine? What does a ifconfig say?

   Although, this brings up a reasonable point -- if they're all on
   the same IP subnet, then you may very well only notice one of them
   getting traffic.

The bug is in the PCI specific code in that old kernel still in the
UP-1.1.9 distribution, upgrade to the latest sparc kernels and all of
the happy meals will work just fine.  And in fact the problem was that
interrupts were not being setup properly so the other cards would
never see them.

Let's stop speculating please...

You need to update to the latest kernels, it is a bug in setting up
interrupts for the 2nd and 3rd cards on PCI.

I'm using kernel 2.2.2.  Today I'll try to compile 2.2.4

Thanks,

Flavio
