Two simple TCPIP / FTPSERVE questions.

2011-07-06 Thread Colin Allinson
This is very basic and simple but I can't seem to see the answer anywhere (although it is probably staring me in face). Once TCPIP has decided that it has tried to restart a server (FTPSERVE) the maximum number of time and abandons further attempts - how can I reset this once the problem has

Very simple way: set up a small Linux instance and install Nagios on it. Configure a FTP probe in Nagios, and configure a notification to a user on the VM system. The Nagios system will test the FTP server by connecting and attempting to transfer a small file periodically. If it fails, it sends

Depending on how the FTP server fails, you might also see it in your performance monitor... Also true. OTOH, there are failure modes (such as the one Colin mentioned about getting unhappy with a minidisk) that won't show up in the console log or will show misleading symptoms (large buffer

David, I am afraid we are in lock down here (essential maintenance only) so no chance of installing a new LINUX server. However, I could use your idea from an existing hartbeat server between VM systems. World work, I'd think. That'd also catch the socket timeout delay problem if/when you
