range of Ports


Hi all..

My distribution is fedora 9 and RHEL 5.3 in both the systems port range is ...

Code:
[root@TEG Sample Scripts]# cat /proc/sys/net/ipv4/ip_local_port_range 
32768	61000
This indicates local port range that is used by TCP and UDP traffic to choose the local port.

Why it wont start from 1 ? why it is starting from 32768 and ends at 61000 any reason ?

Thanks in advance...

The lower numbered ports are typically reserved for specific uses by internet standards, the high ports typically aren't. Usually only root can start a process that opens on a port below ~1000.

See the /etc/services file for a mapping of 'IANA well known ports' to service names.
