Hi all, I have a problem and have an idea to solve it but I dont know how can I implement the solution. This is the scenario: I have a main proxy server (main proxy) configured with round-robin options and connected to 2 parents proxy (proxy 1 and proxy 2. Everything is working fine but if proxy 1 or proxy 2 connection to the internet fails and the connection between the main proxy and the parents proxy still alive the main proxy still do round-robin request to both proxy which causes the page to sometimes opening and sometimes not. now my solution is this from proxy 1 and proxy 2 since both machines have 2 NIC eth0 connected to lan and eth1 connected to the internet I will create a script pinging the internet, if the system determined that the internet is dead it will issue a command ifconfig eth0 down then when the system determined that the internet is alive it will issue a command ifconfig eth0 up. With the eth0 is down either by parent proxy1 or proxy2, the main server cannot see the the dead proxy and will only fetch pages to the alive proxy. Can anybody help me on this kind of script, a script that is based on ttl reply thank you very much, Wennie
