Using netstat to see the listening processes
To see if a program or process is listening on a port, ready to accept a packet, use the netstat program.
netstat -tulnp
The arguments to the netstat program are listed below:
•t – Show TCP
•u – Show UDP
•l – Show only listening processes (netstat can show both listening and all established connections, i.e. as a client too)
•n – Do not resolve network IP address names or port numbers
•p – Show the process name that is listening on the port

Disable swapping for the associated logical volume:
# swapoff -v /dev/VolGroup00/LogVol01
Resize the LVM2 logical volume by 256 MB:
# lvm lvresize /dev/VolGroup00/LogVol01 -L +256M
Format the new swap space:
# mkswap /dev/VolGroup00/LogVol01
Enable the extended logical volume:
# swapon -va
Test that the logical volume has been extended properly:
# cat /proc/swaps # free
