Squint and Squish 2 cute admin tool for Linux :) Rumi, November 9, 2008November 9, 2008 Well, Leading Edge Business Solution from South Africa- do created 2 excellent and to my view most essential tools for network administration to sniff users and warn them! Actually they run on linux environment with Squid Proxy server running on the network to serve clients (likely network clients). From here on I better should express on their tools features- squint generates a little report of who is spending the most time and resources browsing the internet via your squid proxy server. The top offenders in terms of data transfer, number of files transferred and on-line time are reported. squint now also generates a detailed history for each person which can be viewed with a browser. squint is useful for discovering problems with internet usage patterns. To determine on-line time, it is guesstimated that after a “hit” the person is reading the page for the following two minutes. So the measurement of on-line time is unreliable, but the system does provide a warning that investigation may be warranted. squint periodically analyzes your proxy server logs, and produces linked html pages like this. Squish squish stops you from spending too much of your valuable time and your company’s bandwidth browsing the internet. Your friendly administrator can specify how much you are permitted, in terms of the amount of time you spend browsing, or the amount of data you download. This is specified per day, per week or per month. With squish you can … Ration bandwidth Keep people from lazing around on the internet all day Make a per-user MRTG-like bandwidth graph (see example) Semi-automatically handle programs that waste bandwidth (viruses, trojans, spyware) Avoid unpleasant disciplinary hearings Blame the computer for doing what you told it to do Proper use of squish can also solve cockroach problems.
