The file path is prompted after success

Install-m Rinetd/usr/sbin

Install-m 644 RINETD.8/USR/MAN/MAN8

Create profile/etc/rinetd.conf, content format: Source IP Source port to jump IP port to jump to

For example, forward all requests destined for the native 80 port to port 80 of 192.168.4.247

[[email protected] rinetd]# vim/etc/rinetd.conf 0.0.0.0 80 192.168.4.247 80

start the program and add rinetd to boot

[[email protected] rinetd]# /usr/sbin/rinetd [[email protected] rinetd]#  netstat -anltup|grep rinetdtcp        0       0 0.0.0.0:80                   0.0.0.0:*                    listen      25019/rinetd         [[email protected] rinetd]# cat /etc/rc.d/ rc.local |grep -v  "#"/usr/sbin/rinetd -c /etc/rinetd.conftouch /var/lock/subsys/ Local[[email protected] rinetd]# killall -9 rinetd[[email protected] rinetd ]# netstat -anltup|grep rinetd[[email protected] rinetd]# /usr/sbin/rinetd  [[EMAIL PROTECTED]&Nbsp;rinetd]# 

This way, as long as the access to any browser: http://192.168.4.154 (rinetd server address) and access to http://192.168.4.247 the same effect.

Precautions
1. The native port bound in the rinetd.conf must not be occupied by another program
2. The system firewall running rinetd should open the bound native port

-A rh-firewall-1-input-m state--state new-m tcp-p TCP--dport 2222-j ACCEPT

3. FTP-skipping is not supported
