Just wondering if there is a list / guide on what files should be set to either chattr +i or chattr +a?
You could go a little 'crazy' and chattr +i all your major binaries......however my only issue with this is that yum updates will fail until you manually chattr -i and update.
what not to chattr +i or chattr +a?
I operate a small vps account that I tinker with for personal use (I host a few friends web forums).
I am a novice at Linux and trying to learn by reading and extensive Google searches but I have been stuck for several days and I hope you can help.
Exim started failing immediately upon restart after upgrades were installed. I believe it is because it won't fully install due to chattr errors I get when I try to upgrade my server.
I am running CentOS 4.4 and I just installed the latest CURRENT build of Cpanel in an attempt to fix my problems.
I have been tinkering, and fixed a few things but nothing I do fixes Exim. When I run the upgrade scripts or I use Yum, or I use cpanel.
I am logged in through SSH as root, or logged in to WHM or Virtuozzo when I perform any actions.
service cpanel status shows:
cpsrvd dead but pid file exists
entropychat is stopped
melange is stopped
stunnel is stopped
interchange is stopped
qrunner is stopped
When Exim 4.63 is installing/upgrading (I see message elsewhere too), etc I repeatedly get:

What are the ways to find out why a CentOS 5.3 server running cPanel suddenly went offline.
I ran "last reboot -n 10" and "last" and grepped for shutdown calls, but nothing. /var/log/messages.1 reveals nothing as well.
I decided to go with Cent OS after reading about it in the forums here, but I've had nothing but problems trying to install it. I first tried to do a net install but the installation took nearly an entire day because it would keep popping up messages about corrupt files when downloading the package files. Eventually it just gave up or rebooted because I came in in the morning to find it at a message saying "No OS installed". I then burned all 7 installation disks and tried that way, still got a few of the corrupt file messages (but far fewer than the previous time) and made it through the installation only to still have it say "no os installed" again after the reboot. I thought maybe it had something to do with the fact that I was not installing a boot loader (there is no other OS installed anyways) but when I tried to reinstall a third time, this time with the boot loader, it now says that the CD drive (USB) is already mounted on tty2 and I can't even start the installation? WTH!

I want to know how can I setup a VPN server on a centos 4 server through ssh?

I've searched a lot, but mostly centos was not listed, and the tutorials were so complicated.
i have a problem with all my server with RHEL4 or Centos 4.4, when u upload small files on the server the system report a different size, this is a little example
> drwxr-xr-x 2 user user 4096 May 10 11:11 ./
> drwxr-x--- 12 user nobody 4096 May 10 11:16 ../
> -rw-r--r-- 1 user user 7514 May 10 11:11 cred.js
total is about 7+4+4= 15kb
but when i do du -h in the folder
root@ares [/home/user/www/]# du -h
20K
where are this 5kb of difference? i have note that this happend when a site have small files inside, example when u install joomla about 7mb on my server it is 18Mb, the server size block is set to 4kb
I have setup a CentOS 4.5 on a server with no fancy options enabled.
The only thing I have is the ssh service running on port 22.
The server comes up fine but is inaccessible until I login into the console and pings an external IP or domain.
Once I have done this, I am able to remotely login into the server via ssh.
And then few minutes after, the server becomes unavailable again until I do the same routine...ping an external IP or domain.
We like to create the mail accounts through php scripts in mywebsite.com website. So we request you to setup the Qmail with Vpopmail server in our server. As we have the following packages are already installed.
1. Qmail
2. Courier POP/IMAP
3. Horde Webmail client
Please install the vpopmail in the ourserver and configure these four packages to create the mail accounts via php script. So that we can use vaddsuer command in php to create the mail ids annd also imap_open commands to access the mails.
Our server is configured with Plesk control panel.
The installation is very urgent, as our website is going live sooner.
I will make the decision sooner and let us know the cost, as it will be given to the provider sooner.

I asked this question before in the past and I still have to ask it: has anyone used both Ubuntu Server Edition and CentOS? I would like to compare both operating system, in terms of speed, performance, security, and stability.
I have decided to build my new server and use Ubuntu Server Edition 64-bit operating system after using CentOS 64-bit operating system for a bit over a year now.
The reason why I have chosen to use Ubuntu Server Edition is because of the operating system's fabulous reputation among desktop PC users, and its large and helpful support community.
Support is what I need most, and Ubuntu seems to have it. I also am not the best with Linux yet, so it will definitely be needed. Ubuntu also seems to update its software faster than other operating systems.
I hope my decision to switch from CentOS 64-bit to Ubuntu Server Edition 64-bit will not be in vain.
Can anyone compare these two 64-bit operating systems and possibly link me to some reviews, comparisons, and/or benchmark results?
i want to ask any any setting or script can help medo the purpose?
i hope i can set a cron to trace server load every five minutes,
and help me record the load number on a log file,
by the way,
i can trace the past load of my server when i need the data.
I've just signed up for my first VPS with CMBHosting and the person in charge, Chetan Bakhru, seems like a genuinely nice, friendly and helpful person. In other words this new service look promising at the moment.
However ...
When I signed up I selected his CentOS/LXAdmin plan because I figured that with a pre-installed control panel like LXAdmin I could avoid as much ssh as possible and simply get "up and running" more quickly. Plus I have some experience managing my own CentOS development machine, and I know that a special software package I plan to install runs on CentOS "out of the box" -- so I was expecting good things from this new VPS.
But when my account was created LXAdmin did NOT create an FTP admin account for me with root access to my VPS!
Instead it created an account that drops me into web server's document root folder, and this is far too limiting for me. I really need FTP root server access -- and I'm surprised that LXAdmin did not provide this access by default.
Not only that, but it appears that I cannot create a new FTP account that has any deeper access than the existing admin account!
Does anyone with LXAdmin experience know if this is the way LXAdmin normally works by default? Or is this perhaps a special configuration created by my new VPS host?

I found htop much more easier to understand than top and would like to install it on my cPanel CentOS server. I tried executing following command from root shell:
yum install htop
and got following output:
..................Reading repository metadata in from local files

Finished
Parsing package install arguments
No Match for argument: htop
Nothing to do
Not sure if htop is available for CentOS cpanel servers? If so how can I install it?

I'm planning to run RAID 1 on my PowerEdge 860 server running CentOS 4.4 (320gb x 2 SATA II).
After doing much research, I've decided to go with 3ware 9550sx.
I have some questions regarding installing the 3ware on an existing system with an OS already installed - How do I go about doing it?
I've read that CentOS 4.4 already has the drivers for it.. Do I just configure the RAID config during the boot up?

I am thinking of limestone 8gb Q9300 server (64bit) with their 30% off deal.
if i can create 2 VPS with completely different OS such as CentOS5 and Windows 2003 Std.
The main server will be running CentOS with HyperVM.
The setup:
2wire BT router (Firmware 6.1.1)
1 Server (Dell) Hardware with NICs (Server is connected to router via Ethernet Cable)
5 Static Ip addresses purchased from BT
Server OS is Centos 5.2
All laptops (5) are able to connect to the net wirelessly. I just did a standard installation of the Centos following [url]
I then tried
Code:
yum update
but it times out. I have no remote access to the server. I can only connect when i am on the router. I have seached, read and tried so many sites and commands but it just is not working. I have had this problem for about a 6 days.
Its a long story but basically this server setup has become a nemesis.
I don't mind providing remote access to the server and router admin page if needed. I am in London btw.
i have a dedicated server with rapidswitch. Few days back all my websites stopped working, due to some reason which i was not able to solve.
NOw, i want to backup all the files stored on my server. Each and every file including the database and every file there on my server.
I tried to log in through ssh on filezilla but i was not able to find out all the folders.
I have putty and could login over ssh , but i don't know the commands to backup.
Could, you guys tell me how to get all those files on my local computer.
i also have cpanel/whm installed and that is working.
Can someone tell me which one is the latest stable kernel version available for centos 5 that should be running on the server?
Is

Outdated?
I want to update CentOS from:

What steps I need to do to install CentOS 7?
