resolving names it is really slow slow with CentOS5.x using named
by carlopmart 26 May '09

26 May '09

Hi all, I have a problem using named with different CentOS5 servers (2 servers): all they are really slow to resolv any internet address and most of time fails to resolv. This situation differs if I use "forwarders" servers like opendns: resolving names it is really really quickly. And I don't understand why. On the other hand I have tested three DNS servers using Windows 2003, Windows 2008 and Ubuntu hardy and these problems doesn't occurs (I don't need to configure forwarders on any of them): all resolves any name and really fast. IPv6 is disabled on both CentOS servers. Somebody knows why these dns servers are slow?? Thanks. -- CL Martinez carlopmart {at} gmail {d0t} com

I have 2 Dell Latitude LS's that work work fine out of the box with CentOS 4.7 and 5.3. They barely meet the i686 cutoff date. JohnStanley

I'm not sure what the firmware does exactly. Look in your /var/log/messages file. There will be some mention of 'failed to load firmware' associated with the driver load. You need to have a partitular file living in /lib/firmware/ -- the name is wired into the driver. The SMC Ez Connect card needed something called isl3890. I don't remember where I got this. My Intel card needed ipw2100-1.3*, this I got off a site after googling for 'firmware ipw2100' (or something like that). Getting the Intel was easy -- there is a web site with all of the info needed. Getting the prism firware was a bit of a hassle. You might have to unpack a file from the CD that came with the WiFi card -- this means you need some Windows tool to unpack/install it someplace and then copy the magic file from where the Windows installer/unpacker puts it to your Linux box and make sure it has the proper name. It is important to get the correct version for your card. -- Robert Heller -- 978-544-6933 Deepwoods Software -- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows heller(a)deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/

The last two even had the internal wireless work without effort. You may need to do some work to get the wireless functioning okay - NetworkManager seems to help if you use both wired and wireless. For me the advantage of using CentOS is that all machines have the same stuff in the same place, so I do not waste time looking for files and trying to work out how Ubuntu or whatever distro does something. Also, I keep a local mirror of updates so I only need to use bandwidth once to get my updates. I used to use Fedora, but got annoyed at having to do complete updates every 12 ~ 18 months. I'd just try it and see, one can always grab another distro if CentOS is really too difficult to get functioning. Rob

Granted, you ain't gonna get multi GB throughput, same as soekris, but by goodness they are stable and reliable, zero moving parts, and as for ALIX/WRAP series, pretty neglible power requirements.

I replaced the EIDE cable, but the problem of After I posted this yesterday, I turned my wife loose on her computer and it choked. Possibly a coincidence, after receiving SMART warnings for a couple of years, and it was ready to die. Thought I had 2 used hard drives, in perfect condition, but the first one I installed turned out to be DOA and now the other one is installed.. :-) Thanks to everyone who replied. As Mark (MHR) wrote, I too was skeptical of the SMART warnings from the BIOS and when I checked on the Compaq Support site, a couple of years ago, I was told the Compaq BIOS is very sensitive and there are a lot of false warnings.

gethostbyname clarification
by Joseph L. Casale 25 May '09

25 May '09

I have an issue, although it's a result of sketchy code in the sip implementation in Asterisk that's been around forever, I am sure I am going to have to fix it some other way as many people have waited with no fix yet from Digium. If a name resolution fails for a remote sip peer, the entire stack tanks and local sip phones don't work either. We have several sip trunks and an analog trunk for redundancy when the SIP providers are down. Problem is if the net connection is down *nothing* works. Most people suggest to run your own caching nameserver which we do. We had long outage and sure enough eventually all the sip phones couldn't connect. I fear in hard coding the remote sip peers in the hosts file incase that changes. The server was also restarted which I believe clears out the name server cache? Is there some way I can configure nsswitch.conf from "hosts: files dns" to something like "hosts: files dns file2" so if those ip's ever changed I would have time to figure it out and update the file unless another outage occurred at the same time :)? Anyone got a better idea how to solve this dilemma? Thanks! jlc

lacie drive and CentOS 5.3 question...
by Ray Van Dolson 25 May '09

25 May '09

I'm adding a couple lacie external USB drives to my CentOS 5.3 system and running into a few issues... when I connect them, I see the following in dmesg: usb 1-1: new high speed USB device using ehci_hcd and address 11 usb 1-1: configuration #1 chosen from 1 choice And that's it. No device assignment information, the usb-storage module does not appear to be loaded and I am unable to access the drive. I do see the following in lsusb: Bus 001 Device 011: ID 0451:6250 Texas Instruments, Inc. I'm assuming the kernel or udev doesn't know what to do with the given device ID and isn't correctly mapping it to the usb-storage module (I have manually loaded usb-storage with modprobe usb-storage prior to attaching the device). I found a post describing how to manually map a vendor id / device id to usb-storage, but it has to do with the old hotplug system from CentOS 4. Can anyone advise me on how I can tell my system the above device is a mass storage device? Do I need to write some udev rules? These drives work fine (automatically) on a Fedora 10 machine. Also, I am using the "plus" kernel on my CentOS machine. Thanks, Ray

System hang during shutdown (halt)
by Camron W. Fox 25 May '09

25 May '09

Alle, I'm running V5.3 (newly installed) on an FJ E8020 laptop. The problem I have is when shutting down (*not* rebooting). NetworkManager fails to stop and after (during?) the postfix shutdown, the system seems to hang. I cannot access via another screen or remotely. I can't find any clues in the log files. I could use some suggestions on troubleshooting.

rsyslog expression based filters
by Kanwar Ranbir Sandhu 25 May '09

25 May '09

Hello All, Does the rsyslog version in CentOS 5 support expression based filters? I'm asking because a filter I believe should be working, isn't and I cannot figure out why. I'm trying to get the following expression working (might wrap): if $source == 'astappsrv2' and $programname == 'asterisk' then /var/log/asterisk/astappsrv2.log Every time I restart rsyslog, I get this error (slightly edited to make it fit): rsyslogd:unknown priority name "log" rsyslogd:the last error occured in /etc/rsyslog.conf, line 16 rsyslogd:warning: selector line without actions will be discarded The line rsyslog is having problems with is the expression based filter. astappsrv2 is the log client, and it's successfully sending it's logs to the remote log host (the one on which I'm having problems with the expression filter). I know the logs are coming in because I've setup property based filters that all work just fine. I can take this to the rsyslog list if need be. I wanted to try here first. Regards, Ranbir -- Kanwar Ranbir Sandhu Linux 2.6.27.21-170.2.56.fc10.x86_64 x86_64 GNU/Linux 13:46:04 up 1 day, 14:56, 4 users, load average: 1.03, 0.41, 0.14
