I'm trying to arrange my 4 NIC's on CentOS 5. Two of them are build-in motherboard nic's and the others are PCI-E Dual Intel card. I'm wondering if someone succeed with udev renaming rule based on BUS location like ID=="0000:03:00.0" ... etc
View 4 RepliesThe line I currently have is:
[code]alias fixname="rename 's/[(),]//g' * && rename 's/ /_/g' *"[code]
I can't figure out how to add in so that it removes apostrophes too.
When I setup the server I added multiple ips. Now that I need to edit ip info I can't find any alias files in the network-scripts folder. But restarting server the ips work fine. Is there some where else that this would be stored.

Reading the history in the CentOS Bugzilla and the upstream's Bugzilla, they recommend doing this within the udev rules. See:[URL].. So, I created a new udev rules file that looks like this, as filename /etc/udev/rules.d/50-eth_tso.rules:
ACTION=="add", SUBSYSTEM=="net", NAME=="eth0", RUN+="/sbin/ethtool -K eth0 tso off"
ACTION=="add", SUBSYSTEM=="net", NAME=="eth1", RUN+="/sbin/ethtool -K eth1 tso off"

Can anyone out there figure out just what I'm doing wrong - I've been struggling with this for about 2 hours trying to make it work, and simply can not figure it out - and would like to not resort to hacking the problem and adding the ethtool commands to /etc/rc.d/rc.local!

View 3 Replies View RelatedI have encountered the same problem as indicated in this post: "udev hang after upgrade from 5.3 to 5.4"[URL]... I'm testing the upgrade path to centos 5.4 on several virtual machines prior to upgrading our production systems. I have upgraded centos 5.2 --> centos 5.4 and centos 5.3 to centos 5.4. In both cases udev hangs after the upgrade. The following message is displayed on the console: "Starting udev: Wait timeout. Will continue in the background [FAILED]"
I found another related post: "udev hangs on boot for a long time, suspect pam_console_apply"[URL]..So, I booted by VMs using the "udevdebug" option to grub and received the same error message - "udevd-event [###]: run_program: Waiting ## seconds for output of '/sbin/pam_console_apply /dev/..."
In my /etc/ldap.conf file "bind_policy hard" is commented out. I added a line "bind_policy soft" as described in the post and my VMs booted fine. NOTE: This problem is not encountered with a fresh install of CentOS 5.4 and the "bind_policy hard" option in the /etc/ldap.conf is commented out as in the upgraded systems. What is really causing this problem and how do I get it addressed? I have a couple hundred systems to update from various releases of CentOS 5 to the latest current version 5.4. It would be nice to get this bug squashed..

i have linux server application based on centos 5 that run httpd daemon from /usr/local/pf/conf/httpd.conf which is generated from the /usr/local/pf/conf/templates/httpd.conf.apache22 file
the problem is every time i run my linux server application i am not able to access phpmyadmin unless i stop my linux server application which is stop it httpd daemon then start "service httpd start"
i have been told by forum moderator to create an alias for my phpmyadmin in Virtual Host but it stil dont work, i am not able access my phpmyadmin site
this is what i have done to solve this problem
- open /usr/local/pf/conf/templates/httpd.conf.apache22 file then look for <VirtualHost *:%%admin_port%%>
- add Alias /phpmyadmin "/usr/share/phpmyadmin" (Failed)
- add Alias /phpmyadmin /usr/share/phpmyadmin (Failed)
- add Alias /phpmyadmin "/usr/share/phpmyadmin/" (Failed)
[Code]....
NB : my phpmyadmin is install on /usr/share/phpmyadmin with /etc/httpd/conf.d/phpmyadmin.conf as phpmyadmin configuration file
why i still cant open my phpmyadmin site ? or why i cant run phpmyadmin together with my linux server application because it use the same daemon (httpd daemon)
I have just completed an upgrade from 5.3 to 5.4 (64bit) Now when the system starts it gets to Staring udev and then hangs for about 2mins before printing "Timeout" and then continuing.
At various stages during the boot process it just stops with no warning and takes a while to restart.
My boot time in 5.3 was about 50seconds, now with 5.4 it is about 4mins.
My issue is: I am "locked" on kernel 2.6.18-164, I just can't get my server up and running with any later release. It simply hangs at "Starting udev".
The hardware is:
MB: Asus M2N32-Deluxe
CPU: AMD Phenom(tm) II X4 920 Processor
Boot FS: Ext2
RootFS: xfs
RAM: 4Gb
I have 2.6.18-194.el5 running on other machines.
PS: I'm about to install/update a fresh 5.5 disc for testing purpose anyway. I'll update here if it works.

Have just installed 5.4 64 bit on an AMD64 x2 system with 4 GB ram running ESXi4.Text based install went fine, but on reboot starting up it gets as far as 'Starting udev' and just hangs. Checking the performance in ESXi it appears to be using 100% cpu.I have left it for half an hour and it does not progress and the only thing to do is to power cycle the VM.I have searched and found a few suggestions for kernel parameters but they did not make any difference. I can't even get in to a command line as it doesn't boot up far enough.I have reinstalled it several times and also checked the MD5 of the downloaded file and all appears Ok.
View 2 Replies View RelatedI have to move our DNS server to our VMware environment. With that comes a new IP address (10.10.102.x). The current address is in the 192.168.10.x. range. Is there a way to bind an alias to my NIC that has a different IP range? I tried it and it didnt work but if i used two IPs in the same subnet range it works. What are my options?
I don't want to go around and modify all my clients to use the new IP. I have many other things running like Nagios and Puppet. Unfortunately this is going to suck and I probably dont have any other options.
I know I can rename my network interfaces (eg 'eth0' to 'lan', 'eth1' to 'net' etc) but does anyone know a way I can alias (symlink if you like) 'lan' -> 'eth0'
I want to be able to use more legible interface names in things like iptables rules (such as "-i lan" instead of "-i eth0") but I don't want to break any config that is expecting eth0 to exist....
I'm running ubuntu 9.04 and I have set up 2 ip aliases using the /etc/network/interfaces file http://pastie.org/775037 -- when I ping the main address 10.0.2.16, all works fine, same with the first alias 10.0.2.22 -- but I can't reach the 2nd alias 10.0.2.23 I get the following from ping:

My machine's IP address is 10.5.0.34 I can't figure out why I can ping 10.0.2.22 but not 10.0.2.23 -- seems like there is probably some kind of routing thing that I'm missing, but I'm confused how it would have gotten set up for 10.0.2.22 but not 10.0.2.23 -- hopefully someone out there has an idea -- or can point me to references where I might be able to learn how to debug routing issues on a network?
I haven't updated my centos box for almost about a year, my theory is if it ain't broke don't fix it.These last two weeks I've been replacing hardware, a motherboard, memory, processor, and a hard-disk. Everything worked fine with the current 2.6.18-128.1.10, but I decided that I should upgrade to the latest along with all the new packages. But in doing so I would need to recompile the driver module for the raid controllers, rr1740. So I recompiled them using the 2.6.18-164.1 build while I was in kernel 128. When I was done, I restarted the machine and when it booted to the new 164 kernel, it came back very long error messages but here's what I can remember off the top of my head.
View 14 Replies View RelatedIs there anyway you can configure either OpenVPN client or the system to allow connections using OpenVPN to be made to computers on the OpenVPN network using their alias rather than their IP address. This may sound blasphemous but you can in Windows. That is if the VPN network is say 10.x.0.x I could connect to Comp4 or Comp2 using Comp4 or Comp2 not 10.x.0. 4 or 10.x.0.2 or whatever IP is allocated by the OpenVPN server. If the OpenVPN server has not been restarted then it will usually allocate the same IP every time the same client connects.
View 8 Replies View RelatedI'm hoping someone knows about this one... I'm running the latest CentOS 5.4 with kernel 2.6.18-164.15.1.el5 (x86_64).When I boot the machine, it gets to the udev starting bit, hangs for like 5 minutes, then prints a message "Failed, will continue in the background." Then it boots OK after that.I tried booting again with the kernel option (from grub) "udevdebug", and what I saw when it tried again was a million messages saying it was waiting for "/sbin/pam_console_apply" to return, but I guess it wasn't returning... ;) Again, after 5 minutes, it gave up and finished booting.Now, this host is an LDAP client.
I figured that may have something to do with it as it is likely that pam_console_apply tries to make an LDAP lookup, which is wrong, because networking hasn't even started yet. If I disable LDAP (by removing ldap lookups in nsswitch.conf), I get no pam_console_apply errors from udev and it boots quickly. But that's a bummer, I need LDAP on this box, and I don't want my boot time to be 7-8 minutes. ;)Presumably before, when LDAP was enabled and it waited 5 minutes and then notified me that it will "continue in the background", that it was eventually successful after networking started. LDAP otherwise works fine on this box, just like all the other servers we have.This is new behavior, I've not seen it with CentOS 5.3 and below. Has anyone seen this? Any hints on what I can do to avoid it? It seems like a pam bug or something, but I don't know for sure.
I having a problem with my network. I'm trying to assign an IP alias of eth0:1 to eth0. If I use ifup eth0:1 is fails and corrupts the network. Making the network useless. But if I just enter 'ifconfig eth0:1 10.1.1.51', it work fine? My scripts look like these:
Code:
:network-scripts; cat ifcfg-eth0
NAME="System eth0"
DEVICE=eth0
ONBOOT=yes
[Code].....
When setting up an alias for eth0, the interface works as expected for normal traffic, but does not receive broadcast traffic.
Host 1's setup:
Code:
Pinging host 1's normal interface from host 2 works as expected:
Code:
Pinging host 1's alias interface from host 2 works as expected:
Code:
Broadcast pinging from host 2 only gets a reply from host 1's real interface (as well as some other uninteresting devices on the network):
Code:
I have confirmed by listening on both interfaces using netcat, and broadcasting using netcat, and again only the real interface receives data.
Is this by design, or is it possible to get interface aliases to receive broadcast traffic?
Basically I am looking for a simple way to create a universal nickname/alias for a interface.We ship servers that have upto 6 NICs on them. The user can have those NIC configured as either ethN, bondN or vlanN interfaces. As we need to provide NIC status information we would like to be able to run commands such as
Code:
ifconfig INTERFACE1
that would map to whatever the user had already configured.
How would I rename all files with a leading decimal point recursivley? I some how got all my music files to have a decimal point.I tried the below and got a " sed argument to long".[CODE]find /media/MUSIC -type f -name "*.wma" | xargs -0 sed -i 's/.(.*)/1/'[CODE]
Another question, can i just use -type f with out -name ? I am sure that all the files got the decimal point added as the first character.
I'm trying to set my network interfaces so that they don't get random every boot.(eg assign eth0 to a network interface with a given MAC addr, and eth1 to the other one)I trew in a udev rule (in fact just modified the rules that was automatically generated and set the ethX in it) but the system ignores my udev rule.What am I missing ?Here is all the info :
Code:
$cat /etc/udev/rules.d/70-persistent-net.rules
# This file maintains persistent names for network interfaces.
[code]....
For some reason, Ubuntu keeps assigning my network interface wrong MAC address. This happens only after fresh boot (I have dual boot with WinXP, if I start Windows first and then restart to Ubuntu without switching computer off, the MAC is correct). Contents of /etc/udev/rules.d/70-persistent-net.rules:
Code:
# PCI device 0x10ec:0x8136 (r8169)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:22:19:ef:1c:3d", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x168c:0x001c (ath5k_pci)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:17:c4:78:f4:f8", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0"
[code]....
EDIT: I made a workaround by adding
Code:
auto eth0
iface eth0 inet dhcp
hwaddress ether 00:f3:f5:ef:fe:56
to /etc/network/interfaces and it works. However, I'd still like to know why Ubuntu ignores my udev rules, regardless whether the workaround happens to work or not...
I have got a problem in the configuration of the network for my Linux box. The distribution is Slackware 12.2 with the 2.6.27.7-smp kernel. There are three ethernet NIC, one on the motherboard with Atheros AR8121/AR8113 chip and two on PCI card which with RealTek 8169.
I installed the module for Atheros which is the atl1e.ko and I defined the configuration for the three NICs in /etc/rc.d/rc.inet1.conf.
When I hit the commend ifconfig I see all the three interfaces eth0, eth1, and eth2, but the address are not distributed between the NICs as I'd like so I thought to resolve the inconvience with udev, but I don't know how to proceed because there is a strange situation.
If I control the file /etc/udev/rules.d/70-persistent-net.rules I see a strange situation: Once the file contains nonly a line for the Atheros NIC but if I reboot the system there are the two lines for the two RealTek NICs and everytime the system is rebooted there is a change between these two alternatives. A detail I noted is that the two modules atl1e and r8169 are both always loaded, so udev has always the chance to detect the hardware but for some reason that I don't know something goes wrong. Another related problem that bothers me is the absence of udevinfo and udevtest. Have I perhaps to reinstall udev?
I'm just installed Fedora 14 64-bits into a server which come with Multiple network interfaces, I'm found that the naming of each network interface is not in sequences in what I'm thought (e.g: the on board network interfaces name as Eth5 and Eth6, the additional card ethernet port name from Eth0 - Eth1 and etc). How to name the interfaces as what I wish to? What should I install to allow me to rename the interfaces.
