[CentOS] Cloning Centos server with RSync - what to exclude?
Hi all, I have a few CentOS servers that I want to mirror live, to be standby spares. The "spare" machines could be either a different machine (with a different motherboard), or a VM in Vmware server. I've used rsync in the past, which works well for doing it while the machine is live. However, I want the destination to be running different hardware, and have a different IP address assigned to the nic. My goal is to rsync everything -except- the files that pertain to the network interface, and the file system mount points. My process is this: 1. Install Centos on "spare" machine, configure for proper ethernet. 2. Rsync from live to spare, excluding files pertaining to NIC and FS. Then if it needs to go live, I simply change the IP address, and I'm off and running. The question is: what do I exclude? I know /etc/sysconfig/network-scripts/, /etc/fstab, and /etc/modules*, but what else? I think there may be some stuff in /var also that deals with raid, etc. The live computer is running software raid, while the backup will not.

[CentOS] Net-SNMP interfaces out of order
Hello Centos People, I have a CentOS 5.3 box that had a total of 5 ethernet cards in it. It functions to share an internet connection with 4 different subnets. All works fine, except I'm noticing that my MRTG traffic graphs are wrong. Further digging with snmpwalk reveal that the order of the ethernet interfaces changes every time the machine is rebooted to a different order. For example, I currently see: IF-MIB::ifDescr.1 = STRING: lo IF-MIB::ifDescr.2 = STRING: eth3 IF-MIB::ifDescr.3 = STRING: eth4 IF-MIB::ifDescr.4 = STRING: eth0 IF-MIB::ifDescr.5 = STRING: eth1 IF-MIB::ifDescr.6 = STRING: eth2 IF-MIB::ifDescr.7 = STRING: sit0 Why is this not in proper order? Other servers seem to be ok. my snmpd.conf file has little, if anything as far as config. Is there something I need to put in there for persistence?

Re: [CentOS] Router for SOHO network - hardware considerations
I am looking for something similar to this thread.. Is there a way to make a small CentOS distro that is bootable and runnable from only a USB memory stick? It would need to be able to have files modified, but I wouldn't want the USB stick to die prematurely due to a ton of writes...
