Server :: Check If CPU And Board Support VT Or AMD-V?
Apr 18, 2010
I have a server running ESXi. I want to know if it supports AMD-V for hardware-based virtualization. Is there any way to check it from one of the guest os running (centos 5).
Also, I tried rebooting the box and I can't see an option in the bios to turn on/off Virtualization. Although from Asus site they say it supports is:
[URL]
The motherboard is an ASUS KFN4-DRE and has 2 Dual Opteron 2216 2.4GHz processors.
Also, on a side note, I have another box with HDAMA board and 2 Dual Opteron 275s. Do these support AMD-V as well? No option in bios as well.

I am impressed with 11.4 and am happy that for the first time ever I don't need to install a kernel patch to support my on-board nVidia graphics. However, the on-board sound no longer works now. I don't know how to set it up in phonon. My device number 0 in phonon is MCP72XE/MCP72P/MCP78U/MCP78S high definition audio, and I assume this is my nVidia on-board sound card. The driver information states snd-hda-intel.
How can I check what is wrong with it? It did work fine on 11.2 right up to the 11.4 installation. I do get system sounds (like the start-up and shut-down sounds), but nothing from any application, e.g., firefox playing a video. Based on the advice from another thread I tried: speaker-test -c2 -l5 -twav This does not produce any sound, but gives the following information: speaker-test 1.0.24.2
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 96 to 1048576
Period size range from 32 to 349526
Using max buffer size 1048576

I'm trying to find out when QME2572 (Qlogic) card became support by the kernel. We have a RHEL 5.1 system that is moving to new hardware, however the kernel at this release doesn't support the new hardware, due to the Qlogic card change. I tired the Redhat KB and Bugzilla. Is there a Kernel change list etc I can search. Never really played around with the kernel too much so I'm just after some pointers for looking up this information. Offically its not supported until Redhat 5.3, I'm trying trying to research kernel info so I can tell the customer they have to upgrade.

Found about this website in vector linux site,you can check before you buy if the wireless adapter works with linux or not, so I think is a good tool to check wireless adapters by manufacturer, interface or chipset, it even have links to the drivers websites,

I tried to install Ubuntu Server on an Alix2d2 board: [URL]It has a CF card connected with an IDE interface and no vga output. The processor is a AMD Geode. I'm aware that I need a 386 kernel as described in the german wiki:
[URL]
What I did so far:
Installed imedia linux PCengines Alix build [URL] on an other Ubuntu machine with usb cf interface. This worked but I don't know how I can install Ubuntu from imedia linux.
Installed Ubuntu Server on the same Ubuntu machine. Installed the 386 kernel and changed the grub config file to enable the serial output to a terminal and updated grub[URL]. I created the file /etc/init/ttyS0.conf that the serial interface still works after the bootloader [URL].Unfortunately the alix board writes only "GRUB loading." and some empty lines.
Tried to boot with Tftpd32.exe by Ph. Jounin following this guide: [URL] So I set up a TFPT server following this german wiki: [URL]As advised changed /etc/inetd.conf and /etc/default/tftpd-hpa, prepared the boot image and the DHCP server. This should be enough on the server. I have to write N over the serial port to the board while it performs memory test to enable PXE boot. This was partly successful: it gets an IP adress but afterwards nothing happens. I can't find any error message in the syslog.
I attached my configuration files. As boot image I used [URL] and used the following commands to bring it into the right place:
Code:
sudo tar -xvzf netboot.tar.gz -C /var/lib/tftpboot/
sudo chown -R nobody:nogroup /var/lib/tftpboot
installing Ubuntu Server with PXE or from the other machine to the CF card or even directly from imedia linux.

I run an ISP with various servers such as mail servers.Once something works I let it run forever. Thus I have a mail server running FC5 on a Mach Speed pm400 via chip set motherboard.Recently the motherboard died, and I had to use a back up board to get it going again.I am now out of back up boards and need to purchase a new set for the future.However the mail server software will not activate the IDE DMA on these newer boards because the chip set drivers are not in the last kernel package that yum would download for FC5.
1.) Is there an easy fix to this problem to get the DMA working?
2.) Do I have to download and compile a latest kernel (2.6.x) to get the right drivers?
3.) Since FC5 is fully modularized, is there an easy way to create a similar kernel from a download without having to manually turn all the modules on?
4.) CAn I simply use the original .config from my existing kernel in the new one?

I have a Phenom II X4 955 box running 8G RAM. Now I'm planning building a Phenom II X6 box running 16G RAM. But the 4G module/stick is very expensive, not easy to find. However most mobo can take max 4 sticks. I can't find mobo board on market except server taking 8 sticks.

After searching the forum I could not find a clear answer to my question so I am giving it a try...
I have installed a LAMP server with Postfix as mail server. The scripts send email as user www-data using the mail server on the same machine.
However, the email got rejected by external mail servers (failed reverse DNS check) so I setup a mail server that meets all needed requirements.
Now I would like to use this second server instead of the mail server on the LAMP server. I found that this could be done with changing sendmail settings in php.ini (I think).
However I am not sure how that will go: www-data is no actual user on the new email server (which requires authentication before sending). Do I need to create a new user on the email server or change the settings in php.ini to match an existing user?

I would like to implement something when a server is offline for whatever reason. For example. I got my own DNS servers and webservers. I would like it if the users goes to www.somedomain.com and the server it is actually on is down for maint. or For whatever not able to respond. What can be done so that if the server isn't able to be contacted that it can point to either a another server or the dns somehow can display a page stating who to contact to report a problem or to let them know its down for maint. And can goto a site to check the status or whatever.

I'm looking for an easy way to check if some server is down, and then act upon it. This check needs to be done from the backup-server. So if the backup-server thinks the production server is down, then in some bash script I want to execute a rule.
My question: what is an easy way to check another server ?
1. I know about Nagios. It's great, but to large to use here.
2. I could ping the server, put a ping that fails does not necessarily mean the server is down.

I want to recompile Apache in order to be SNI supportive because I need to use ssl named based virtual host:
I referred to the following links:
[URL]
I installed the latest version of openssl which is now openssl-1.0.0 I ran the following commands:
./config enable-tlsext --prefix=/usr/local2 --openssldir=/usr/local2/openssl
make
make test
make install
then to recompile apache with new SNI support I ran the following:
./configure --enable-so --enable-ssl --enable-rewrite --enable-unique-id --with-ssl=/usr/local2/openssl
make
make install
After that when I start Apache: /usr/local/apache2/bin/apachectl -k start I get the following error:
SSLStrictSNIVHostCheck failed; OpenSSL is not built with support for TLS extensions and SNI indication. Refer to the documentation, and build a compatible version of OpenSSL.

I have a service the uses Mono to check in with a SQL server at a set interval. For some reason in 11.04 The service is only able to run for a short period of time without crashing. This service worked/works perfect in all previous versions. Any ideas as to what could have possibly changed? I'm really just looking for ideas on what to check.

I need to check my mailboxes for errors. My imapd has permanent errors, it periodically crashes. I think that the problem will be with some errors which was created when I converted my previous maildirs to mailboxes.
It is possible to check the integrity of these mailboxes with some command or script?

I am using this command (inside a bash script) to check if mailserver is running correctly (port 25)
# echo | telnet localhost 25 | grep "Connected to "
If it does not respond I receive an email alter.
It works good , but sometime it NEVER respond (neither after 1 hour) , so I receive no notification . DO you know alternative command to the command above ?
