Nagios, Big Brother, Big Sister, and others are good for Go/No Go checking of hosts' and servers' aliveness. I am most familiar with Nagios. It can take actions on detected problems like e-mail an alert to your cellphone/pager. It saved my system once. I turned off the A/C to clean the outdoor exchanger. Forgot to turn it back on. Went into town to write and sip a latte. In about an hour I received the temperature warning message, halfway home I received the temperature critical message. Made it home with the ambient temperature over 90F and the CPU temperature in the mid 50C's (130F's). 60C is about all the manufacturer warrants. Nagios will ping hosts. Connect to HTTP, SMTP, IMAP, POP, etc. servers. Query SNMP agents. And run scripts. Nice. HTH, Jeffrey -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
