What tools to use to diagnose network disconnections
Posted on 2007-11-19
I have a network running on a watchguard VPN firewall with 2 24 port linksys managed switches. I have several remote locations connecting in to the watchguard device.
I have 3 centrally located servers, 1 is a Windows Domain server, 1 is a ScoUnix server and 1 is a Linux Server. I'm running Powerterm Plus on windows xp machines as well as Neoware Dumb terminals to connect to the Unix servers.
At this time we seem to be intermitentantly losing connection to Unix server.
I would like to start testing the network for this failure but I'm unsure of how to go about it and what tools to use.
I have created both a Linux and a Windows box with network testing software such as Cacti, Wireshark, Aipcap, netdoppler, commview.
I'm not sure if these are the tools I should be using for this problem or how to really use them well. I have only just started to learn about these things.
