What mother boards work with CentOS?
I tried:
Intel
Gigabyte
Asus
and DFI
But all those either does recognize the nic card or wont recognize a a sata drive.
Does anyone know of a motherboard where CentOS will recognize the nic and sata drive?
Trying to figure out the hardware configuration I'll need to host a message board and was wondering if those of you with experience could throw out some numbers in terms of # users, bandwidth used, and what hardware configuration you're on (single server, dual server, dual proc, RAM, disk, etc). Been tricky trying to guestimate so some numbers to compare would be a huge help.
View 7 Replies View RelatedWe are starting to look for new motherboards for LGA775 1333 MHz FSB Intel Core 2 Duo chips and I'm wondering what boards other people are using. Support for the new Core 2 Duo E6xxx/E8xxx series chips is a must.
Our qualifications for boards is that they must work out of the box (or very near to out of the box) with CentOS/RHEL 5 and must fit in a SuperMicro SC512 case with no modification (meaning: working NIC & low profile audio).
My server has 4 GB of RAM, and is running Cent OS 5.3 (x86_64).
I'm just wondering how to understand the memory usage readings that I get. Running top gives me:
Quote:
Mem: 4038696k total, 3272388k used, 766308k free, 243832k buffers
Swap: 2096472k total, 0k used, 2096472k free, 2321692k cached
However this is a completely new server, and at the moment nothing is really running on it (I haven't got any clients on this server yet, I'm still setting it up). Does that reading mean that around 3 GB of RAM is being *used*? Also, at first the server's mem usage was at about 1 GB, but it's slowly been increasing (again, without really running anything on the server).
Also, under WHM's Server Status page it says that "Memory Used" is "18.1%" - how come this is so different to the top reading?
I know that CentOS/linux overall handles memory different, so I'd appreciate any insight into things
since i have few of them, doing nth but eating dust there. How can i make most use of them?

What is the difference between CentOs 5.0 and Centos 4.5? (Both contains Plesk)
Would CentOS 5 contain more updates and fixes? CentOS 4.5 be more stable?
Does it worth to upgrade cent os to latest version on server where is installed whm/cpanel?Could i request upgrade from cpanel support ?

Please post, comments, questions, etc. here.
I've myself upgraded many servers this way, (even, tonight, I upgraded another, so I finally decided to do this with all my notes)
im using centOS 5 with webmin in my vps.

I'm having exec cgi issues,
CentOS 5.3 x86_64, Linux, Apache/2.0.63,
cPanel 11.24.4-R36167 - WHM 11.24.2 - X 3.9
Error is,
[an error occurred while processing this directive]
If I "uncheck" IncludesNOEXEC in Apache Global Configuration the error disappears, but the SSI doesn't work. If I check it the error is there, but the SSI works.
Here's what I have done so far,
Through WHM,
Main >> Service Configuration >> Apache Configuration,
Pre Main Include, Pre VirtualHost Include, Post VirtualHost Include,
I added,
Options +Includes
AddType text/html .htm
AddType text/html .html
AddOutputFilter INCLUDES .htm
AddOutputFilter INCLUDES .html
Options +ExecCGI
AddHandler cgi-script .cgi .pl
I also added this to the httpd.conf
<Directory "/">
Options +ExecCGI FollowSymLinks Includes IncludesNOEXEC Indexes -MultiViews SymLinksIfOwnerMatch
AllowOverride All
</Directory>
Options +ExecCGI
AddHandler cgi-script .cgi .pl
Then I tried,
Options +ExecCGI
AddHandler cgi-script .cgi .pl
in the .htaccess file

View 4 Replies View RelatedAfter spending nearly 4 days trying to get ftp working on my server i still haven't achieved it. I got a server with a default install of plesk and cent os 4. I update to 8.2 and when i first go to try ftp it says "server closed connection" on my ftp client.
So then i tried updating 8.2 again and the installer failed. So i tried manually installing both proftpd and pureftpd via ssh and yum and it fails to install. I've also restarted the server a few times. I've tried logging in with every single username/domain/i.p. assigned to the server. and i've had no luck.
I installed Lighttpd + PHP 5.2.1 with FastCGI
Any php page that starts with <?php is working fine..
but when the page starts with only <?, it does not work
how does SSH work and really what is it.
This is my knowledge, I may be wrong or right:
There are two ways of controlling your server, through control panel and through SSH, now SSH is where you type in codes to control your server.
Now from what I know you can't login to SSH alot due to security reasons.
I was wondering, if I have a forum can I login to SSH everyday to back up the database?
Whenever I tried to upload large files to my server it restarts the upload again and again and never actually uploads. It just keeps overwriting the previous file. I don't get any errors? It just automatically reuploads and overwrites the files everytime.

service iptables save
service iptables restart
But when i run netstat command abouve, i found IP are attacking still available, it seem iptables don't block it?
I would like to know how servers work, like how to build, set up, and how they work, what software is in them? Also could I own a server and send them to a data center and host them there?
Also a little infomation on Data Center. Could you share me some knowlage.
some clarification with regards to Reverse DNS.
An example ip: xx.xxx.xxx.xx is owned by A Company via a DC. The they have their name allocated to the netname and description when i look up their ip address.
I have my ip xx.xxx.xxx.xx this is me and it currently contains my DC's name throughout when i look it up as the description and netname...
Both are from the same DC however the other company has their name allocated to the ip address and i would like to do the same. Does this require Reverse DNS? It dosent involve domains surely does it?
I try to install wordpress on my dedicated server but in the begin i get this error:
Your PHP installation appears to be missing the MySQL extension which is required by WordPress
I have centos 5.3 and i have run the command: service mysql start
But i think mysql server is not running, because i have kloxo and from the panel i can see what servers are running.
I have been using apache and php-cgi and it works well together but when I tried to use
mod_rewrite it stopped working and I got "Internal Server Error" result.
Apache error log showed "FastCGI: incomplete headers (0 bytes) received from server"
I think that mod_rewrite rules are ok because when I refer to some HTML file then it all works.
Apache 2.2.14 and php 5.2.11

View 7 Replies View RelatedHow can I best work with a syn flood? I've tried the apf, deflate-ddos etc.... and don't work. Even tried litespeed etc but doesn't work against a 90mbps attack.
If I get a few servers, how would I have it setup to best defend?
I'm working on a new project that involves some heavy data processing in the preparation stage. As an example, one of the setup jobs is now running on a P4-3.0HT desktop at 100% CPU and I estimate it'll be finished in just under a week! Memory and i/o usage are minimal but it's extremely CPU-hungry.
There are other similar jobs to follow and some correlation between the number of cpu cycles and the quality of results so I foresee an ongoing need for computing power for at least a few months.
Viable options are to continue running my own hardware (probably supplementing the P4 with something a bit newer), Amazon EC2 or a cheap dedicated server - I can get a good handle on the cost and performance of each of these.
But I wonder if I'd get more bang per buck from a few VPSs? Some of the VPS benchmark results are spectacular so I suspect the answer could be yes, in the short term anyway. But I don't want to hog the host-node's CPU to the point where it degrades other users' performance or gets my account shut down... Then again, judging by the performance of the VPSs I've used for hosting the node seems to have a lot of spare CPU available...
So (finally) to the questions: Am I crazy to even consider this? If not, which technology would be most suitable? (I'm thinking Xen because of its reputation for better isolation.) Has anyone else done anything similar?
I sent email through php function mail - false.

Like the title says, I just moved my site over to my own server, and it is running cpanel. Anyways the main site [url]works, but [url]does not.
What is really strange is, [url]works fine as does [url]
So I figure there is something I have to do to get it all to work right.
The other issue is that if you are logged into [url]but goto [url], you are not logged in anymore, but if you go back to the original link, then you are still logged in. This happened on the other guys server before with the main site as well.
