dansguardian + squid performance question

Hello,

  I have been considering running dansguardian + squid on my system in the background in order to route my kids computers thru it.  What kind of performance hit can I expect to see on my PC when running dansguardian and squid as background processes.  The most intensive thing I do on my PC is run World of Warcraft via wine.

AMD 2100xp
1 GB Ram
SATA 120GB HD

squid wouldn't cause too much of a performance hit, unless you have a sizable amount of traffic running through it.
DansG on the other hand, depending on how you configure it, can use up a sizable amount of cpu (content filtering isn't 'cheap'). Your box isn't really 'underpowered' though.

But..I would say you should be fine. If your kids are surfing the net and you are playing WoW, you likely wouldn't notice it too much, I wouldn't think...

But I have never played WoW, so I don't know what it does to a box..

No harm in trying it out. If it slows things down too much then get a cheap PC to use as a proxy.

How old are your children? If they're very young you should consider a whitelist which will reduce processing. If they're older or you think a whitelist is too restrictive you have more admin work to do and more processing e.g. turning on  reverseaddresslookups, checking  blacklists etc. You should also look at the google patch.

When I voluteered to help run a youth Cybercafé, they were spending £30 per pc per year on net nanny software - DG is better. I put a few linux PCs in and cancelled the net nanny subscriptions. We have been running squid with dansguardian and dnsmasq for a couple of years now.  I have a Smoothwall box (550Athlon with 128MB ram) sitting next to me with that software on, which I hope to install in the summer break.
