We did a cursory check and it looked like Dansguardian is the best tool out there. The key to dansguardian is that you can get up-to-date filter lists. Dans can use a good bit of memory but I haven't really calculated how much. Top shows me a lot dansguardian processes, each using about 10K of RES memory, 980 of SHR, and 0.5% of Mem. What I understand about top and memory is that it doesn't really tell much at all b/c the processes are using shared memory. to date we haven't had any issue running 2 schools and our office thru one server running dansguardian and Squid. Yes, I know this is not an ideal solution. We don't have dans and Squid running on the School's XS's currently, but we intend to in November. > When you mention it blocks most content, I'm less than thrilled.
