Most of the tools I will talk about are Linux based although some of them do have windows ports. <\/p>\n<p>One program I really like called <a href=\"http:\/\/www.ex-parrot.com\/~pdw\/iftop\/\">iftop<\/a>. It tells you how much bandwidth is being used by what connection on a given interface. The main advantage of this compared to Etherape is that this is a text program so it can be run over a ssh connection (Secure Shell, lot more secure than telnet). Helps you identify what program is using up your bandwidth and who is running it.<\/p>\n<p>If you want to be notified every time a new machine comes on the network then you should check out <a href=\"http:\/\/linux.maruhn.com\/sec\/arpwatch.html\">arpwatch<\/a>. It lets an admin know whenever a new machine requests an ip address from his dhcp server. Very useful on a small network where not a lot of new computers are added each day. This helped me plug a hole in my wireless network.<\/p>\n<p>This is all for starters. I will be posting more links as and when I get the chance but I plan on making this a semi-regular feature so check back often.<\/p>\n<p>&#8211; Suramya<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Was getting bored and thought you might like to know what kind of tools a system administrator\/network administrator has in his disposal to monitor his network and systems and what stuff we sometimes find while using them.
