Gentlemen, I have a question regarding yum groupinstall vs just using yum install. I have been reading tutorials online (for example how to run a Centos LAMP). Most of the tutorials have examples to install httpd, mysql, etc using yum install httpd.... The reason for this e-mail is that I noticed in yum grouplist that there is an option to install Web Server, MySQL database server, etc.

CentOS Community, I was wondering if anyone had a good resource or procedure for a step by step in installing a mail server with Centos. There ARE documents on google, however almost all that i've found were outdated from 2005. Does anyone know where I can find this type of document for a mailserver Postfix + MySQL + SpamAssassin + ClamAV + Squirrelmail + Postfixadmin, etc?

I am inquiring about how to setup a proper SPF record. I know there are SPF wizards/generators available but each seem to have a different "opinion" of what should be included and what should not be included. Let me give you a scenario of my setup, and hopefully someone can help me out. My domain is: test.com My mailserver hostname is: mail.host.com which also has a MATCHING PTR

I know this was discussed before, and I have seen a million ways of doing this via online docs. I have a quick question that hopefully the community can help me out with I am trying to add a block of 10 IP addresses. Rather then create 10 different alias files, I want to use the RANGE file. Docs say to use the following format: IPADDR_START=x.x.x.x IPADDR_END=x.x.x.x CLONENUM_START=0 If the

Good day, I was wondering if there was a way to change the hostname for each individual IP address allocated to a system. For example if only one NIC card is being used (single port) and the hostname of the machine is "example.example.org", this hostname is being displayed for all applications no matter what IP I set the application to BIND to. My server has multiple IP addresses

CentOS Community, It is to my understanding that the /boot partition should never be placed on LVM and should be a physical partition on the hard drives (or on top of a RAID array). Is this an accurate statement? Also please advise if the SWAP filesystem is safe to be placed under LVM, or if this should be a hard partition / hard limit as well. I am unsure if boot issues or any filesystem issues

CentOS Community, What commands can I use to check the disk health of the system when LVM2 is being used on top of a RAID 10 using a HARDWARE 3ware raid card. The OS sees a hardware raid usually as one big drive. Is there a way to check the disks individually to see if any are failing, or throwing hard or scsi transport errors?

Good Evening All, I have a question regarding CentOS 6 server partitioning. Now I know there are a lot of different ways to partition the system and different opinions depending on the use of the server. I currently have a quad core intel system running 8GB of RAM with 1 TB hard drive (single). In the past as a FreeBSD user, I have always made a physical volume of the root filesystem (/),

I know this is a bit off topic from CentOS itself, but are there any DNS experts that would be able to e-mail me on the side and assist with some questions I have regarding TXT/SPF records? I want to ensure my mail doesn't bounce.

Just a trivial question... Do the hosts allow and hosts deny clauses (i.e. within smb.conf) support the use of IPv4 CIDR notation (e.g. A.B.C.D/maskbits) ? The specific documentation page I was looking at, i.e.: https://www.samba.org/samba/docs/using_samba/ch06.html was rather entirely ambiguous on this one small point. When describing the interfaces clause, it says explicitly that CIDRs

CentOS Community, I have a dedicated server with 4 hard drives in a RAID 10 software configuration running LVM. My OS is CentOS 6.2. Earlier today, I rebooted my system and my system did not come back online. I opened a ticket with my datacenter who informed me that one of my hard drives is no longer recognized by the bios and has failed. I was told that an OS reinstall was needed. I

Good morning all, I currently have a website that was written in ASP back in 1999. The system is currently running Windows 2003 Server with MsSQL. Before everyone flames me for being in the wrong place, I was wondering if there is a way to allow centos to run old ASP code? I know years ago this wasn't possible without a program like ChiliASP, but noow I heard rumor that apache might have
