There are repository rpm packages for RHEL4 and RHEL5 . The repository package installs the repo details on your local
system for yum or up2date to use. Then you can install packages with your usual method, and the EPEL repository is
included.

10 Port Forwarding
By:
Stephen Carville
Rev:
08/23/02
Port Forwarding is also possible using OpenSSH (Sec 17.2).
10.1 Using xinetd redirect function
The simpliest and, in my opinion, the preferred way to handle redirecting unencrypted connections is to use the redirect
capability built into xinetd.
If necessary, add services names to /etc/services. For example:
geofwd 50005/tcp # GeoTrac forwarded port
1. Add service file to /etc/xinetd.d. Example file:
# default: on
# description: forward connections to indian:1005
service geofwd
{
flags = REUSE
socket_type = stream
wait = no
user = root
redirect = 192.168.124.4 1005
log_on_failure += USERID
}
2. Restart xinetd
# /etc/rc.d/init.d/xinetd restart
10.2 Using Netcat
The netcat utility is sometimes described as the ‘Swiss Army Knife” of the network. Here we are using it for very basic
port forwarding from an externally accessible server to an internal server. If it is not necessary to run the forwarding
service continiously, on Redhat it is prefereable to use xinetd forwarding.
1. Install netcat from CDROM or from ftp
# rpm -Uvh ftp://volga/pub/RPMS/nc-*.rpm
2. Add services names to /etc/services. For example:
geofwd 50005/tcp # GeoTrac forwarded port(netcat)
3. Add service file to /etc/xinetd.d. Example file:
4. # default: on
# description: forward connections to panama:1005
service geofwd
{
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/bin/nc
server_args = 192.168.124.38 1005
log_on_failure += USERID
}
5. Restart xinetd
# /etc/rc.d/init.d/xinetd restart
