Install Apache Http Sever using yum

> yum install httpd
> service httpd start

Check what all ports running

If you know the port at which that service runs then issue the following command
[vijayan@boarddown-dr ~]$ netstat -an | grep LISTEN | grep 80
tcp 0 0 0.0.0.0:807 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:5801 0.0.0.0:* LISTEN
tcp 0 0 :::80 :::* LISTEN

To know which process id owns this port
[vijayan@boarddown-dr ~]$ sudo /sbin/fuser 80/tcp
80/tcp: 25529 25530 25531 25532 25533 25534 28522

To know which executable/script runs on that process id
[vijayan@boarddown-dr ~]$ ps -lfwwwwwp 25529
F S UID PID PPID C PRI NI ADDR SZ WCHAN STIME TTY TIME CMD
5 S root 25529 1 0 75 0 - 953 - Feb17 ? 00:00:00 /home/vijayan/dev/Apache2/bin/httpd -k start

Seting gnome on Linux VNC server

In redhat linux, when we start VNC server, by default it used to start with a simple termial based view. Inorder to start it as gnome based session the following command can be used

1. Set the vnc session as gnome
   > vi ~/.vnc/xstartup (remove all the lines and add only the following lines)
   unset SESSION_MANAGER
   vncconfig -iconic &
   gnome-session &
2. Start VNC server
> vncserver - geometry 1024x768

Use the correct ip address and X-display id to connect to the VNC e.g. 10.66.92.127:1
