I am using this on my CentOS 4 machine. I would expect it to work on a CentOS 5 machine as well.
Add the following to /etc/sysctl.conf
net.core.rmem_default = 67108864 net.core.wmem_default = 67108864 net.core.rmem_max = 67108864 net.core.wmem_max = 67108864 net.ipv4.tcp_mem = 4096 67108864 67108864 net.ipv4.tcp_rmem = 4096 67108864 67108864 net.ipv4.tcp_wmem = 4096 67108864 67108864
Run sysctl -p

How can I change Time To Live (TTL) in Centos 5.0 x86?
