scarecrow Posted January 19, 2006 Report Share Posted January 19, 2006 Nope but Mandriva stopped to see the eth0 after have disabled in the bios. So what? That's natural: every onboard component disabled within BIOS does not exist for the OS! HardDrake can be safely disabled, since other hardware detection scripts are present (hotplug, or in newest Linux revisions udev without hotplug- thank god for that!).

Please give a look to the whole post than the situation will be more clear to you. Quote Link to comment Share on other sites More sharing options...
RiccardoPini Posted January 21, 2006 Author Report Share Posted January 21, 2006 Hi to all! Speaking with my dad he gave an idea that if will turn out to be true would sound incredible...my motherboard is the Aopen one with the Tube sound, a thermoionic valve which is very close to the nic cards. All the behaviour makes think that this is the random external agent that prevents the nic to be brought up in the correct way. And this would explain why after a while the nic works properly: the valve when warming up crosses diff frequencies and a particular range could influence the nics. Im doing tests and if so guys i think u can jump on your chairs for this! Quote Link to comment Share on other sites More sharing options...
RiccardoPini Posted January 25, 2006 Author Report Share Posted January 25, 2006 Ok guys dont jump on your chairs...it's keeping doing the usual thing...uff Sorry also for making here ppl mad, but i have really tried all the solutions posted here in the forum but nothing. The event that makes linux go mad is the comp switching off: hard or soft doesnt matter. Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted January 25, 2006 Report Share Posted January 25, 2006 I'm not sure how it can happen. This is what I would do, before installing Linux on your system. If you have it now, erase it and start again, following this: 1. Make sure Plug and Play OS in the BIOS is set to disable. It should not be set to be controlled by the OS. 2. Disable the on-board Realtek card, so that you use the 3COM card. OR remove the 3COM card, and just use the Realtek with it enabled in the BIOS. 3. Install Mandriva 2006. 4. If using Realtek card, make sure APIC is disabled, as you might experience network connectivity problems otherwise. 5. Disable ipv6 by adding the following to /etc/modprobe.conf: alias net-pf-10 off and then reboot to disable it. You need to stop the system from seeing two network cards. My preferred method would be to COMPLETELY remove the 3COM card and just use the Realtek. It cannot get confused if there is only one network card in the machine, therefore it will always be eth0 no matter what. Quote Link to comment Share on other sites More sharing options...
RiccardoPini Posted January 25, 2006 Author Report Share Posted January 25, 2006 Hi! The option Pnp OS doesnt exist in the bios, there's only how the resources are handled, so ill try to disable everything is PnP and manage the IRQs by myself. Also ill reset the ESCD and restart from this point. Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted January 25, 2006 Report Share Posted January 25, 2006 If they are PCI, you should be perfectly fine to leave them as they are. I've never touched anything in my BIOS other than to look for this option and disable it. If I didn't find it, I left everything else as it was. See how you get on, but you really need to make sure there is only one NIC in the machine, so remove that 3COM. Quote Link to comment Share on other sites More sharing options...
RiccardoPini Posted January 26, 2006 Author Report Share Posted January 26, 2006 Im taking away the 3com. In my bios there is no entry PNP OS yes or no, but ive disabled the resource handling from auto to manual then leaving the choice of the IRQs to PnP. Then updated the ESCD. Im reading the plug-and-play HOWTO for Linux found online. I also set as enabled the wake up events related to pci and is set to S1. Also adding in /etc/init.d/boot.local the modprobe eepro100 and disabling the ipv6. Ill keep you posted, Thanks, Ric Quote Link to comment Share on other sites More sharing options...
RiccardoPini Posted January 27, 2006 Author Report Share Posted January 27, 2006 Hi! My actual situation after some tests of yesterday eve are these: the Realtek nic which is the only nic in the comp behaves correctly, i can ping it and if i ask an ifup through console or using the tray icon i see it going up. I can ping it and i have a good feedback. When i try to ping the router i get an "host unreachable" mesage even if everything is well set up in the mcc: gateway ip, static ip for the nic, simply host name for my comp. What should i check or config now for override this problem? (I mean let's start from this point: nic ok, getting host unreachable message). Also the router shows the connection led with the nic stable green while i get the host unreachable message. Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted January 27, 2006 Report Share Posted January 27, 2006 Is your router a firewall? If so, ICMP might not be enabled, which is why the router isn't replying. Quote Link to comment Share on other sites More sharing options...

If so, ICMP might not be enabled, which is why the router isn't replying. <{POST_SNAPBACK}> Yep it is: USR router/firewall/switch. Being very stupid i didnt check if there is the gateway dev inside the /etc/sysconfig/network file, but having only one nic now i think mcc should have take care about it editing that file. But how to enable it? Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted January 27, 2006 Report Share Posted January 27, 2006 To check you have configured the default gateway, type this at the prompt: netstat -r or route both will give the same results. You are looking for the line that shows "default". Quote Link to comment Share on other sites More sharing options...
RiccardoPini Posted January 28, 2006 Author Report Share Posted January 28, 2006 Finally im able from that comp to post some text file about some commands. Pls note that the first ifconfig was before the nic started to work in answer to some of my ifup and ifdown. Also ive found the nics works well it's their connection to the router that is lacking.

RiccardoPini Posted January 29, 2006 Author Report Share Posted January 29, 2006 Hi i also took away the sit0 adding the alias net-pf-10 off line to /etc/modrprobe.conf, forced no apic and no local apic, but at a reboot i got the usual situation im posting here the dump that maybe could help: [root@SilicaMkV ri]# ifconfig eth0 Link encap:Ethernet HWaddr 00:0A:5E:53:DF:7E UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:20 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:18314 (17.8 KiB) TX bytes:0 (0.0 B) Interrupt:10 Memory:e3000000-0 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:82 errors:0 dropped:0 overruns:0 frame:0 TX packets:82 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:6644 (6.4 KiB) TX bytes:6644 (6.4 KiB) [root@SilicaMkV ri]# ifdown eth0 RTNETLINK answers: Network is unreachable Also when i do the ruote command i get the list i posted here yesterday but it takes time for find the gateway address. This of course when i cannot connect to the router. At this time after have received the RTNETLINK message i set up again the nic with mcc rebooted and the nic went up. Any idea?

RiccardoPini Posted January 30, 2006 Author Report Share Posted January 30, 2006 I forgot to say that if i do ifup eth0 seems to be useless (no "RUNNING" indication as answer to ifconfig command) and if i then do ifdown eth0 i get the error message.
