Hi Sami, In this case,please refer to http://www.linux-ha.org/ It will help you out with the heartbeat tool they released. You can have your squid servers listen on one virtual ip address(vip) when the primary one goes down,the ip address(vip) will be set on the secondary one by the heartbeat tool automatically. ------------------ XUFENG 2009-06-15 ------------------------------------------------------------- 发件人:abdul sami 发送日期:2009-06-15 13:47:09 收件人:squid-users 抄送: 主题: How to setup squid proxy to run in fail-over mode Dear all, Now that i have setup a proxy server, as a next step i want to run it in fail-over high availability mode, so that if one proxy is down due to any reason, second proxy should automatically be up and start serving requests. any help in shape of articles/steps would be highly appreciated.
