Reinier, You have piqued my interest. Currently I have a Win2k3 box which acts as my File, AD, Print Server , DHCP and Gateway - IP 192.168.0.1. I am assuming that I have 2 options at this point:
a) Setup the caching on the Win2k3 box - what's the best way to deal with this one? b) Setup a caching server - I setup the PIII box, with Ubuntu Maverick + IPCop + NTop and make this my gateway. Is there anything else that I need to do? Thanks in advance Stephen -----Original Message----- From: Reinier Battenberg [mailto:[email protected]] Sent: Friday, October 15, 2010 10:25 AM To: [email protected]; Linux Users Group Uganda Subject: Re: [LUG] Bandwidth Monitoring on a NIC seriously, if you have a network with a fixed connection and more than 2 computers, running a dedicated machine for caching will just make your life a lot happier & shiny. We currently have +/- 25 users in our network on a 1MB/s link. This is the cache stats of the last 24 hours: Total Accesses: 218389 Average Accesses: 9099.54 per hour Total Cache Hits: 151478 Average Cache Hits: 6311.58 per hour % Cache Hits: 69.36 % Total Cache IMS Hits: 17617 Average Cache IMS Hits: 734.04 per hour Total Cache Misses: 66909 Average Cache Misses: 2787.87 per hour % Cache Misses: 30.63 % and in volume: Total Transfers: 3 Gb Average Transfers: 128.4 Mb per hour Total Cache Hits: 228.4 Mb Average Cache Hits: 9.5 Mb per hour % Cache Hits: 7.41 % Total Cache IMS Hits: 4.4 Mb Average Cache IMS Hits: 187 Kb per hour Total Cache Misses: 2.8 Gb Average Cache Misses: 118.9 Mb per hour % Cache Misses: 92.58 % (note that the 3GB includes non-http traffic that can not be cached, like ubuntu-cd bittorrent downloads.) Still, 10MB per hour you dont pay for (free as in beer) is a good deal. That is, 70% of all http requests actually hit the cache! (that is more than i ever saw, it used to be about 30%) So we get 70% more bandwidth than we pay for because requests never leave our building! Buy the PIII while you can still get one + an extra NIC, download IPCop and you do get all the stats, for free. (there is an ntop add-in too) I forgot to mention something i use quite a bit, which is the proxylog. When traffic is real slow, i just have a look at it (its all webbased, any manager can do this) and in most cases find the person streaming from last.fm youtube facebook videos etc. That is if you actually get enough bandwidth from your provider to open any of those pages of course ;-) #lazyweb: if you have time on your hands, configuring the perfect IPCop box, filling up the update-accelerator cache & selling + servicing these boxes to mid-size companies is a GREAT businessmodel. People will love you!
