3 step for change hostname to RHEL Linux: edit: /etc/hosts 127.0.0.1 srv03.mil1.wide-net.org localhost.localdomain localhost edit: /etc/sysconfig/network HOSTNAME=srv03.mil11.wide-net.org past into kernel new hostname echo "srv03.mil1.wide-net.org" > /proc/sys/kernel/hostname Or sysctl kernel.hostname=srv03.mil1.wide-net.org Consider a restart net services /etc/init.d/network restart but is not strictly required.

Rate Algorithm: defines data rate algorithm convergence: Optimistic Algorithm is aggressive enough to move to a higher rate but yet tries to conservatively capture the fluctuations of the RSSI. It starts with the highest possible rate and then decreases till the rate can be supported while periodically transmitting packets at higher rates and computing the transmission time. The optimistic rate algorithm always looks to achieve highest throughput while sacrificing noise immunity and robustness. ...
