CentOS 5 Hardware :: Uhhuh. NMI Received For Unknown Reason 30?
May 20, 2010
Im having a hanging problem with a HP dl160g6. uname -a shows:
Linux mail.xxxxx 2.6.18-194.3.1.el5 #1 SMP Thu May 13 13:08:30 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
The server was working fine since November �09 until a month or 2 ago.Sometimes (almost daily now) the machine hangs and shows the front "health led" blinking red.The services do not respond,locally i can see the login screen but when attempt to logon it freezes (the same happens with ssh).2 weeks ago i open a case in HP and the support sugest that the problem is in the X server (??), since then the system starts in runlevel 3 but the problem continues. A week ago open another case, on Tuesday make a BIOS upgrade but today in the morning the server hangs again.
There�s no strange messages in log files but... after the Tuesday hungs (before the upgrade) i can see the error msg below (thanks to the change to console mode):
Uhhuh. NMI received for unknown reason 30.Dazed and confused, but trying to continue.Do you have a strange power saving mode enabled?
Uhhuh. NMI received for unknown reason 20.Dazed and confused, but trying to continue.Do you have a strange power saving mode enabled?
adding "nohpet" as kernel parameter does not work.

I've been using Fedora 12 for about a month, and i'm very happy with it. Even tough, there's only one thing that worries me, and is giving me problems at the same time. I'm getting an error from: syslog@localhost that says: kernel:Uhhuh. NMI received for unknown reason b1 on CPU 0 kernel: Dazed and confused, but trying to continue. Kernel: seems to be a problem, likely on the PCI Bus
I'm not able to reproduce the problem every time i want, but, sometimes happens when i activate the snow effect combined with the cube effect, using kwin. My computer and OS specifications are: Pentium IV HT(disabled) Nvidia Geforce 8400gs 2 Gb Ram DDR2 (1xGB, 2x512) Hard Drives: 2x80GB Using Fedora 12, KDE 4.4.1, with Nvidia privative drivers, nouveau disabled

I'm running Ubuntu 10.10. Something really weird keeps happening to me, a total of 3 times so far, and given how it occurs. When I click I all of a sudden get a black screen with some output about states and then the gnome login is displayed.
Here is how it happened:
1) I clicked on the close button on Google Chrome.
2) I double clicked on the Skype icon in the panel.
3) I clicked on a dialog in a Windows 7 Virtual Box guest.
why this is occurring? I doubt you will so how the heck do I go about diagnosing something like this?

I just booted up ubuntu, and instead of the beautiful default appearance, my task bar and some of the icons in my launcher (home folder, workplace switcher) look like they were thrown back 5 or 6 years in time.

I am testing about using SSL Certificate in apache web server using Ubantu 10.04.2 (64 bit edition). And I insert SSLcertificate and private.key file into "default-ssl" file in "sites-available" folder. But when I call the website, SSL certificate show "Could not verify this certificate for unknown reason".
Configuration in "default-ssl" is shown below

I'm pinging a certain website and what happens is that each time the ping process freezes for an unknown reason ca. 10-15 sec then it starts to ping. Note that only this particular domain causes this hanging and Ctrl-c seems to have no effect at all! The domain is niteco. So far I've tried several independent linux systems all with the same result however other non-linux systems ping normally.

I tried posting this before and I'm not sure what happened but I don't think it worked, so if it did please forgive the double post.am very very new to centOS and linux in general. I just want to setup a test web server that more closely mirrors our actual web server that is hosted by rackspace. I've installed centOS and tried to setup Apache, PHP and MySQL from a guide on the web using Yum. When I go to localhost in the web browser I'm able to see the default apache page. However when I create a php page it's just blank.When I look at the apache error logs I get this: PHP Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0
I've been searching alot on the internet and I know the issue is permission related, but I don't know how to fix it. I've seen some forum posts that say you need to use the chmod 775 command on the /var/www/html folder.Currently when I do ls -l /var/www/html it returns
-rw------- 1 root root 19 May 5 13:16 index.php
-rw------- 1 root root 19 May 5 13:15 index.php~
I'm sure that this isn't correct but like I said I don't know much about how to set permissions or who the owner needs to be. I've done alot of searching and seen similar posts, but no one seems to explain it clearly.

I've bought a HP Photosmart printer, HP Photosmart wireless e-All-in-One printer - B110a and i've got a problem installing it properly. I'm using Debian 6.0 Squeeze. When i connect the printer, Debian doesn't recognize my printer as the Photosmart B109 printer for unknown reason. When i go to the site of HP and search for a driver, it directs me to this site:I've downloaded that latest hplip file as a .run file and installed it. My printer is recognized proparly, but when i try to print a colored image, it comes out black/white. Something is not crrect. Does anyone recognize this problem with this type HP printer?

Ive been searching half the internet for a solution for a strange problem im having with a server (CentOS 5.2 Final). For no apparent reason, the server will just be powered off.I've looked in the dmesg log and /var/log/messages file, but that doesnt show anything, except the "syslogd 1.4.1: restart." message after booting it up again, and hours in advance of the crash a "suhosin" alert message.

I am using Centos 5.3, and when I try to copy a batch of files, it just slows down and stops, the files are not that big, few megs. first I realized it when I used secure ftp, I thought maybe my internet is slow, but now it does even from an external USB drive,.
I use Krusader for copying.

this should be trivial for all you big sysadmin guys My box is a firewall/gateway. ETH0 is on the Internet-side, and is fully auto-configured (DHCP client) from my ISP. ETH1 is on the LAN-side, has DHCPD enabled, and I route the traffic to/from the Internet via iptables (NATting, of course). Everything works pretty good, except for the DNS-server assignment via DHCP: how can I configure dhcpd.conf to assign the SAME dns-server I receive from my provider on ETH0 to all my PC on ETH1?

we have 22 servers Dell (20 Poweredge R210 + 2 Poweredge R310) with CentOS 5.5 x86_64 (kernel 2.6.18-194.26.1.el5). Half of these are on different rack. During the day, some server reboot without any reason and the messages log file had no evidence of what happened.
From /var/log/messages:
...
Dec 8 14:10:02 hadoop011 snmpd[3029]: Received SNMP packet(s) from UDP: [172.27.1.21]:50825
Dec 8 14:10:02 hadoop011 snmpd[3029]: Connection from UDP: [172.27.1.21]:50825
Dec 8 14:15:26 hadoop011 syslogd 1.4.1: restart.
[Code].....
Some minutes after the reboot, messages log this error: Dec 8 14:18:14 hadoop011 Server Administrator: Instrumentation Service EventID: 1404 Memory device status is critical Memory device location: DIMM_A3 Possible memory module event cause:Multi bit error encountered.
Is it possible that 20% (circa) of 60 memory bank are broken? By the way, memory bank have Lifetime warranty from Kingston. If I reboot again the server affected by this error, the error disappear from messages log file and from OpenManage Web interface.
Is it possible that is a CentOS bug? I had search some relative bugs on Bugzilla but without any results.

i want to resolve the above error. I'm using systemimager to autoinstall system images on pc's connected in lan. while doing this i got the error No DHCPOFFERS received. Also at the time of booting my pc it shows the message No dhcp and/or proxyDHCP offers recieved. But i've started the dhcpd deamon on my pc. Also the systemimager rsync deamon is running. The two pc's are also connected in lan properly.
Still while autoinstalling the image on client it fails showing the error message... No DHCPOFFERS recieved. what do i do in order to make my autoinstall work properly? How do i come to know whether the dhcp server is running or not? What will be the exact problem in autoinstalling?

I have a Sony Vaio PCG-5A1N (built for Japan) which has a malfunctioning CD-ROM. The bios doesn't support USB external CD-Drives and it doesn't have any USB boot either.The only method, I am left to work with is the PXE boot. I have finally setup a PXEBOOT on another CentOS server and everything works fine all the way to choosing language etc....but after it grabs images/stage2.img this is what it gives me:
loader received SIGSEGV! Backtrace:
[0x8048cf4]
[0x300420][code]...

I am using Postfix on CentOS to send mail through a relayhost. The mail sends fine, but on certain clients such as the mail client on the iPhone or Windows Live Mail, the message is received with '(No Sender)' in the sender field. The Apple Mail client on the iMac works just fine.
Here is the PHP code I am using to send the mail code...
Wondering if there is a configuration setting in /etc/postfix/main.cf I can use to fix this problem. I have scoured the help files but have come up empty.

In linksys router I have host as servix and domain as example.com. So why is it returning unknown host?

when I try to send emails to new created emails account, I get this error:
<teste@topdapop.com>: Recipient address rejected: User unknown in virtual mailbox table�
And if I try to send a e-mail, the authentication fails if I setup the account at the desktop email client to password requirement on.
But it works when I try it using a webmail client (Horde) and I receive the email.The old emails accounts work fine. The new accounts and old ones were created with Plesk.I find an entry with
/usr/local/psa/admin/sbin/mail_auth_view | grep teste@topdapop.com
I get no output from
strings /var/spool/postfix/plesk/virtual.db | grep teste@topdapop.com
Using mchk and mailmng does not seems to change that.
I also found the file /etc/postfix/virtual.db .strings /etc/postfix/virtual.db : no output

we use for the installation of our machines bladelogic. We have different servers. Some servers have only one network interface, but it can be 2, 4 or may be more. There is always one network device for using PXE, but it is not always eth0.Is there any way to run kickstart without the entering of the PXE-Device so, that kickstart checks all the network devices in the system?
