[CentOS] Wake On LAN
Hey Listees I can not work out how to get my Dell NF500 III server to use wake on LAN using the on board Broadcom NetExtreme II BCM5708 NIC card? I'm running Cent OS 5.3 final (i386). Basically, If I had windows server 2k3 installed I know that the cards & mobo etc support WOL I would just have to tick a little box under the NIC card properties saying "allow wake on LAN" (or words to that affect). How can I enable WOL for my NIC card? I have two identical servers so I have tried putting one to sleep (via either setting the hibernate time down to 5 mins and waiting for it to time out and hibernate or by running the following as root: echo shutdown > /sys/power/disk; echo disk > /sys/power/state) and waking it up with ether-wake and WOL (an rpm package) but neither worked, also with a windows WOL client from a windows server which I know works as it is regularly in use but the system didn't come up. The light is glowing green on the mobo just next to the two on board NIC's (both are the same BCM5708's); the light is on but nobodies home? What setting might I be missing within CentOS its self to keep the cards alive when the power is out? Any help is greatly appreciated.

Any help is greatly appreciated. I don't know about your Dell, but on my HP ML110 servers, I had to add a line to ifcfg-eth0 to make ethtool tell the LAN port to enable the wake-on-lan function: ETHTOOL_OPTS="wol g" You will need to take the interface down and up after adding the line.

[CentOS] ata_piix
Hi all I am using cents 5.3 on a gigabyte motherboard MA78GM-US2H. When installing centos using kickstart I get prompted to load a driver. I select the ata_piix driver and everything continues as normal. Is there a way in kickstart or the boot command prompt line to specify loading the ata_piix module automatically? Why isnt the kernel loading it automatically? I dont recall having to ever do that before in 5.2 Thanks, Jerry ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Port Forwarding woes
I'm having some port forwarding issues issues with iptables. We are using iptables as a firewall with 2 nics and on ip alias. I'm trying to port forward on the alias ip eth0 = 65.x.x.1 eth0:1 = 65.x.x.2 eth1 = 192.168.x.x I'm wanting to forward certain ports(80,5071...etc) that makes request on eth0:1 IP 65.x.x.2 to forward to internal IP 192.168.x.x. I have setup the following rules but I must be doing something wrong. iptables -t nat -A PREROUTING -p tcp -i eth0 -d 65.x.x.2 --dport 80 -j DNAT --to-destination 192.168.x.x:80 iptables -t nat -A PREROUTING -p tcp -i eth0 -d 65.x.x.2 --dport 5071 -j DNAT --to-destination 192.168.x.x:5071 iptables -A FORWARD -p tcp -i eth0 -d 192.168.x.x --dport 80 -j ACCEPT iptables -A FORWARD -p tcp -i eth0 -d 192.168.x.x --dport 5071 -j ACCEPT Any help would be greatly appreciated.

[CentOS] Reset audio controller w/o rebooting?
As I mentioned on a thread about flash-plugin a few days ago, I'm having trouble with my sound device getting "stuck" and thereby causing problems for anything that accesses it, like video playback. Rebooting the machine "fixes" it for a while, but it's unpredictable for how long -- sometimes months go by without it recurring, sometimes it happens every couple of days. Right now I'm in one of the latter phases. Any suggestions on how I could reset the controller without having to reboot? (Or suggestions for where else I might ask this question?) Below is output from "lshw" for the audio controller, and "lsmod" for the sound modules that are loaded.

Further more this really seems like a Bug in the way Applications handle killing processes. Why? I have a Client this happens to often. Exactly the way you describe. One idea why it affects my clients machine is it is running 4.7 and is dog dead slow. Wait 5 minutes and the processes finally exits. In theory it should exit when the app is closed. johnStanley ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Unfortunately that doesn't help. Once the machine is in this state, then even after using "lsof" to track down all processes that are using the sound device, and killing all of them, the *next* thing to access the sound will play for a few seconds and then lock up. I once got it to clear up by unloading and reloading all the sound-related kernel modules, but that doesn't repeatably work either. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] kickstart problems...
Hi, I am creating CentOS install usb keys and, apart from a few problems, it mostly works... 1. OT: My server HP does not seem to want to boot on it if I set the write protection on. 2. Anaconda tries to fetch the ks.cfg too early... It detects sda, then detects the RAID adapter, then re-detects sda with a "waiting for device to settle before scanning". Anaconda tries to access the ks.cfg file in the middle of this waiting. If, once the detection is over (just 2-3 seconds later), I retry, it works. 3. Error message "cannot mount read/write, will mount read-only" (I like to write protect) 4. OT: fs corruption ont he USB keys... I copy the iso file on the key (no error message), then compare it to the original and some random differences appear. I noticed in the logs: "ext2_new_block: Allocating block in system zone - block = 65536" "ext2_free_blocks: bit already cleared for block 88678" "ext2_free_blocks: Freeing blocks not in datazone - block = 3003818537, count = 1" Any idea how to fix 2. and 3. ?

The fact you are getting connection refused suggests that the traffic is going somewhere and responses are getting back, rather than disappearing into a hole, which is good... Are you sure traffic to that address is getting to your eth0 interface and not going to another device or being blocked by your router? Capturing traffic using tcpdump while testing would confirm this, i.e. tcpdump -i any -n port 5071 would show packets coming in on eth0 and going out on eth1 if everything is working, or only coming in on eth0 if something within this box is preventing forwarding, or nothing at all which would show that the traffic wasn't even making it to your machine... d ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

What type of machine is this as in Brand. The one I'm see the problem on is a HP 400Mhz Celeron 254MB of ram. My thinking for my clients problem is it is a real slow machine and the processes are taking a long time to exit. But you have to reboot the whole machine. What is the mixer your using? You may can try looking at the Sound Preferences Devices Tab to change the options there to see if that will help.

Why do you want CentOS on an EeePC ? It's not really intended for that purpose, if your having to ask where to get the drivers for it your probably not suited for running CentOS on the EeePC. Your better off with Fedora, or Ubuntu or something that has broader hardware support. I installed Ubuntu 9.04 netbook remix on my EeePC 2G surf yesterday(onto a 4G SD card), it was pretty painless although the general UI has too much eye candy, so it is choppy.

I have a strong if perhaps irrational preference for the .rpm family; I have indeed installed and run F8, F9, F10, and Eeedora on this machine. Unfortunately, until I can afford to replace it with a somewhat larger netbook, what's left of my eyeballs and fingers limits me to using it in waiting rooms, and not much of anywhere else. Given that limitation, speed of boot becomes a major criterion. F10 (and also, believe it or not, Pupeee) took *over* ten minutes -- yes, real sixty-second minutes; it's not a typo -- just to boot.

Run /sbin/lspci and find the hardware info for your wired / wireless device. Then search the CentOS wiki. For example, if you see "AR5007EG", there is a wiki page for that: http://wiki.centos.org/HowTos/Laptops/WirelessAR5007EG If you also see "Atheros", there is a good chance that you can find the latest driver that is available as the kernel module at the ElRepo repository ( http://elrepo.org ). For example, if your device requires the atl2 driver, you can install it by (after installing the repo): yum --enablerepo=elrepo install kmod-atl2 Hope this helps, Akemi ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

The point of that rule is to drop anything you did not handle before. That rule is supposed to be the last one in the list of rules. The best solution in your case is probably to move your other rules above that one. HTH, Filipe ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Fedora 10 suspends/wakes properly on my Acer Aspire One I have done much with that and posted some useful stuff on the FedoraProject wiki page on Aspire One.

[CentOS] php-mcrypt from c5-testing is the wrong version
Hello all, I am using the c5-testing repo to fetch PHP 5.2.6 and related libraries, required for the LAMP apps that I want to use. php-mcrypt still seems to come from the extras repo and is version 5.1.6 and the php binary doesn't load this module. Any ideas on howto get php-mcrypt 5.2.6?

[CentOS] Dell mirror raid boot problems
Everyone, I was recently given a Dell raid 386 server that had drives that had gone bad. I replaced the drives with a couple terrabyte sata Seagate drives, and set up the bios for a mirrored raid configuration. I was able to install Centos 5.2 without difficulty, but when it was time to perform the 1st boot it went to grub instead of booting off of one of the mirrored drives. I could not figure out how to boot through grub, so I changed the bios to look at both drives unmirrored. At that point I was able to boot to one of the drives, and the second drive was not mounted. The raid logic is within the bios and mother board of the Dell machine. Can any of you point me to some literature about making this system work as a mirrored raid system.

Surely, this isn't a 386 (16 to 40mhz from circa 1989?!?) What Dell RAID controller model does it have? They are pretty much all called PERC something, but there are many generations.

Admittedly I'm not up on the newer PERCs, but the older ones I've used were mostly LSI Logic/AMI Megaraid hardware, with Dell firmware, and seemed pretty damn solid to me.

There are more than a few people on this list using Dell servers (which a vast majority use PERC controllers.)
