Hi Rajesh,

Thanks for the insight. But my doubt is that the PCI Express devices
down the hot-pluggable slots are working fine. i.e. if we forget about
the hot-plugging / unplugging, the bridges and devices are working
fine, even with ACPI enabled.

So is the presence of bridges in ACPI namespace required only for
hot-plugging / unplugging and not for normal operation?

Thanks,

Rajat

The chipset is the Intel Lindenhurst chipset.

I am using the PCI Express Switch(Bridge) NEC uPD720401

Denying access to a service by port number in hosts.deny

Dear All,
Is it possible to deny access to a particular service
in /etc/hosts.deny by its port number.
for eg. for sshd can we use port 22 as below

22: 192.168.100. EXCEPT 192.168.100.100

i own a server from dell 2800 ,which also use the intel SE7520
mainboard with the lindenhurst ,but the technicans in dell said that
the MSI support is limited and therefore cannot use native mode of
PCIE hotplug

Hi Rajesh,

Thanks a lot, for ending my doubts. I am working on a hardware that is
still under development. So the chances of missing certain things in
hardware / BIOS are high.  So the solution for this is to ask my
Hardware vendor to provide the information for these bridges into the
ACPI namespace (AML / DSDT?)?

Thanks a ton,

Rajat

Netconfig Fail


Hi,

Slackware 10.1 kernel 2.4.29

My onboard LAN card on the mobo failed and I had to switch to an external LAN card.

I disabled in BIOS Ethernet onboard. Then I did netconfig. Slackware found the LAN card I entered all
necessary data and the configuration went w/o any errors.

However, I cannot connect to the Internet. On booting after the MAC address was found it should produce the
the IP address which it does not. It just sits for a while then continues booting. The same happens when I do /etc/rc.d/rc.inet1.

Ifconfig naturally shows no connection just the loop-back.

Where is the hitch?

I had no problem in Fedora4 to configure the new Lan card and in the gem Damned Small Linux distro, where I am
now, the new LAN card was found w/o me doing anything.

Help for slackware appreciated.

Thanks & regards

Peter

I have a broadband connection and had no problem with netconfig and the onboard LAN card.

Just to be clear ... the relevant kernel module does identify the card 
and create the eth0 interface. Right? (One way to check: use "ifconfig 
-a", which  will list *all* interfaces, while "ifconfig" by itself only 
lists *configured* interfaces.)

At this point, I'm still uncertain as to whether the kernel module is 
failing to find the NIC, or the NIC is failing to get an IP address.

"produce"? Do you mean you get an IP address via DHCP? Via PPPoE? (These 
days, home broadband connections rarely come with static IP addresses, 
so I surmise you don't have one of those rarities.)

In any case, troubleshooting is easier if we know how it is *supposed* 
to work.

Have you tried booting knoppix? It is often helpful to try it out, and then 
you might be able to tell if it's a hardware problem, or software setup 
issue.

if it works under knoppix, try issueing a lsmod from the command line to find 
out what modules are loaded. Then, rmmod the ones that might be the network 
card, until it stops working, write that one down, reboot and try modprobing 
it to see if that makes the card work.
