I checked the SMART attributes of the drive and nothing untoward, also executed the smartctl -long .... test wich came back error free.

Realtek chips are junk with unpredictable reliability, especially under heavy load. I have had several problems with various versions of the 81xx chips. When I tossed the cards in the garbage and switched to Intel-based NICs, all the problems went away. Every time I build systems with Realtek network chips on the motherboard, I disable them in the BIOS and add Intel NICs instead. YMMV, but please consider ditching Realtek altogether. Chuck

Hanging issue with sudo command
by Kaplan, Andrew H. 21 Jun '12

21 Jun '12

Hello -- We are running Centos 5.2 64-bit on a system that functions as a mail server, and also runs a virtual server via the Virtualbox application. A user account was given sudo access via the sudoers file several years ago, and that account has worked well with various administrative jobs on the server. Recently it was observed the user account took longer to complete its login from a terminal window and console. It is also now having problems when running the sudo command. Essentially when the user runs the command, the latter hangs, and the administrator is forced to log in as root, and kill the hung progress. What would cause this issue to occur, and how can it be corrected? Thanks. The information in this e-mail is intended only for the person to whom it is addressed.

how is this possible?
by Bob Hoffman 21 Jun '12

21 Jun '12

I got a spam today (from a yahoo server, surprise!) with nothing but a single link. http:// 2927755261/ I separated the http so it would not be a link in your email... suggest not going to it without proper measures. it takes you to a record search site. When I look up this number block here, http://www.ip-adress.com/ip_tracer/2927755261 it comes up with a different ip address... The ip address has no correlation to the numbers I searched for though. How is it possible to have a url that does not conform to the internet standards? Even ip addresses need 'periods' between each group of numbers.... and everything seems to require a period somewhere or the browser will get angry. At first I thought it was some kind of browser hack, but then the iptrace pulls up an ip. so how is this possible?

Bug in Latest Adobe Flash Plugin
by Keith Roberts 20 Jun '12

20 Jun '12

I'm running Centos 5.7 32 bit with Firefox 10.0.5 ESR Not sure if this has been mentioned on the list yet, but the latest version of Adobe flash-plugin 11.2.202 has a bug which causes it to hang and not play SWF files. I've been pulling my hair out trying to identify why I could not get any SWF videos to play. I finally found the answer here: https://bbs.archlinux.org/viewtopic.php?pid=1080414 I have downgraded the flash-plugin now to version 10.3.183 from rpmforge repo. It works fine now :) I've also added exclude=flash-plugin to the end of /etc/yum.conf file, to make sure this does not get upgraded again.

Failing Network card
by Gregory P. Ennis 20 Jun '12

20 Jun '12

Everyone, Most of the time I am over my head in trying to troubleshoot problems. However, after reading manuals, man pages, and getting advice from this list I have been able to work my way through difficulties, and at the end, I usually have a better understanding of what 'is going on'. I can only hope this method will work on this problem too. I have been chasing a problem with a pci-e TrendNet(TEG-ECTX) gigabit card. After adding the card to a machine with a new Centos 6.2 install and naming it 'eth4' it works well for 6 to 12 hours and then fails. The failure is characterized by dropping its connection speed from 1000 to 100 while not allowing any data to flow in or out. When this happens a shutdown and reboot does not solve the problem, but shutting down and then removing the power does solve the problem. I wrote a perl script that uses the eth4 interface by pinging another machine every 60 seconds to try to figure out the relationship of the message log entries with the time of failure, and I think there is a corelation of the failure of eth4 to function with the below entry. Unfortunately, I am way over my head on this one. If any of you can help I would surely appreciate your thoughts. Some additional information that may be useful. The TrendNet card is the second TrendNet card I have used. The first card had the same symptoms, and I deduced the card was bad, and purchased another one. The symptoms are the same with the second card. Before I purchase a third card from a different manufacturer I thought I would post this to see what some of you think. This is the first pci-e card I have used; are there problems with the pci-e interfaces as opposed to pci? Do you think the motherboard could be the problem, and moving eth4 to a different slot on the motherboard would be worthwhile. Any ideas ??? Greg Ennis P.S.

CentOS-5.8 - Problem booting remote host
by James B. Byrne 20 Jun '12

20 Jun '12

Kernel 2.6.18-308.8.2.el5 I recently experienced an odd problem with a host at our warm-site location. The facility we use suffered an hvac failure during elevated ambient temperatures (30C+) on Monday past and the equipment room reportedly cooked for some hours. It was sufficient that our equipment shutdown. In all probability this was due to an over-temp condition since the systems are all powered from a UPS but possibly there was an extended power out instead. Whatever the cause one of our hosts did not restart subsequent to this shutdown. Which condition required my presence on site. When it was powered up today in situ the host's console would display the CentOS splash screen with the message [press any key to enter menu] and then the message "Booting in ....4 seconds" However, the countdown timer never changed from the initial value and the restart never took place. When I entered the console menu and selected the most recent kernel available the system booted normally. It had to do a lot of disk remediation on the first go through but all that completed without untoward difficulty. Subsequent shutdowns displayed the same behaviour. The splash screen displayed, the boot timer message showed, and then nothing changed thereafter unless and until I entered the boot menu. Selecting the default kernel in the boot menu allowed the restart to continue, this time without any unusual reports. I repeated this process several times more just to confirm that this was not a transient effect. Each time operator intervention from the console was required to restart the system but once this was done no further problems were noted. I repeated the process and rebooted using each of the older kernels present. As far as I could determine there was nothing wrong with any of the boot images once past the auto-select segment of the boot process. I then went into /boot/grub.conf and changed the default boot from index 0 to index 1 so as to use the previous kernel. Following this configuration change thereafter the system restarted normally without operator intervention. The problem kernel was installed from Updates on June 13 and was running from that date as shown in the log entries below. This was a remote restart and evidently it completed without any problem. Jun 13 10:15:59 inet04 shutdown[19274]: shutting down for system reboot . . . Jun 13 10:16:25 inet04 exiting on signal 15 Jun 13 10:18:35 inet04 syslogd 1.4.1: restart.
