similar to: binding additional IP addresses to centos6 on one interface

Hi all Can someone explain me this: ifcfg-eth0-range1: ONBOOT="yes" IPADDR_START="192.168.1.48" IPADDR_END="192.168.1.55" CLONENUM_START="1" Why Bcast is 192.168.1.51 and why Mask is 255.255.255.252 ? OS: Centos 6.3/64bit Thanks Levi # ifconfig eth0:1 Link encap:Ethernet HWaddr 00:9C:02:99:FA:00 inet addr:192.168.1.48

Hello. It happens that at the company I'm working decided to start migration of IPs tech. So they got a /48 block. I were trying to add it with: ifcfg-eth0-range1 (0 is already in use with IPv4 range): IPV6ADDR_START=xxxx IPV6ADDR_END=xxxx CLONENUM_START=0 But of course I am assuming that like in IPv4 IPADDR_START/END is implemented. Please give some guidance as I need this to done

I want to add two IP ranges on one NIC card (eth0 and eth0:1). Has anyone done this before? The CentOS 4 gui keeps locking up when I try it there and the command line ifconfig seems to work, but ifup always returns the error that is never heard (no such device) of eth0:1 thanks

With one problem down I still have another remaining. Since the installation of our primairy webserver we have had a problem with the network aliasses. Our server has 8 IP adresses so we used the tool provided in the GUI to specify (and name - for our own convinience) eth0 aliasses with the other 7 adresses. After setting them up, applying them, activating them and restarting

Folks The price point of Intel's NUC unit makes it attractive to use as a server that doesn't have significant computational load. In my environment, a USB connected hard-drive could provide all the storage needed. I wonder if anyone has had experience with it, and can answer: 1) Does Centos6 and/or Centos7 install from a USB connected optical drive? or a USB flash drive? I'd

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 There ARE documents on google, however almost all that i've found were outdated from 2005.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?

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?

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, 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

Hi I''m very very new to tc iproute etc and have read the LARTC howto. What I want to do is create some "master" classes of bandwidth limit and below that per ip address which "inherits" from this master class. Example: one queue for 128Kbps other queue for 256Kbps What I want now is that for example in "class" 128Kbps the ip 10.0.0.5, 10.0.0.8 etc. goes

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

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 (/),

What's the right way to assign an IP alias to an ethernet interface that you want to bring up and down manually, not on boot? I tried the old way of making an ifcfg-eth3:0 file and it does work with the ifup, ifdown commands, but even though I specified onboot=no, it activated at boot-up. -- Les Mikesell lesmikesell at gmail.com

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

Good afternoon Gentlemen, I have a question regarding /etc/hosts for CentOS 6 x64. I already have a hostname set on my server, however there are 10 additional IP aliases assigned to the box, one which I plan to use as a mail server. The mail server will be serving mail for a completely different domain (different then the default hostname of my box). My question is this: If I take one of my

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.
