Hello all
I have a colony ISP. that shares the 512 kbps wireless broad band internet connection to it's
colony members. i am using redhat9 and have configured transparent squid. and natting too.

the following is my nat configuration...
/sbin/iptables -t nat -F
/sbin/iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 3128
/sbin/iptables -t nat -A POSTROUTING -s 139.61.0.0/16 -o eth0 -j MASQUERADE

#My squid configuration.

httpd_accel_host virtual
httpd_accel_port 80
httpd_accel_with_proxy on
httpd_accel_uses_host_header on

#http_access allow our_networks
acl our_networks src 139.61.0.0/16
http_access allow our_networks

# And finally deny all other access to this proxy
http_access allow localhost
http_access deny all

Now what i want is to select some ip for day surfing some for night surfing some unlimited surfing. i know that it can be performed by writing a script and execute it by using cron but what is the script?? can any one help me on this topic.

My thought is,

Create 3 scripts, each with a different IP address. Name them: ip.night, ip.day, ip.unlimited
Edit your crontab and execute them at certain times.


You should then be able to just copy your current configuration to the 3 files and change the IP address.
----------------------------------
2nd idea

In the crontab. execute the command ifconfig eth0 10.0.0.4 255.0.0.0 replacing the IP and subnet with the IPs you wish to use.

Read the Rules please. Do not double post.
