Setting Up LVS to Load Balance DNS
Greetings, all: OS: CentOS 6.4 x86_64 Kernel: 2.6.32-358.14.1 I could use some assistance with setting up pulse to load balance my dns servers.

local port redirect not working on Centos4
Hello, I want to redirect one local port to another. I am using the following: iptables -t nat -A PREROUTING -p tcp --dport 7003 -j REDIRECT --to-ports 80 and testing it by telneting to localhost on port 7003. It works on Centos3, not on Centos4. No luck with this either: iptables -t nat -A PREROUTING -p tcp --dport 7002 -j DNAT --to 127.0.0.1:80 Am I doing something wrong? Or did something

Hi all! I'm stuck on something really bizarre that is happening to a product I "own" at work. It's a C program, built on CentOS, runs on CentOs or RHEL, has been in circulation since the early 00's, is in use at hundreds of sites. recently, at multiple customer sites it has started just going away. no core file (yes, ulimit is configured), nothing in any of its (several)

Slow read performance
Help please- I am running 3.3.1 on Centos using a 10GB network. I get reasonable write speeds, although I think they could be faster. But my read speeds are REALLY slow. Executive summary: On gluster client- Writes average about 700-800MB/s Reads average about 70-80MB/s On server- Writes average about 1-1.5GB/s Reads average about 2-3GB/s Any thoughts? Here are some additional details:
