The biggest thing I've found that speeds DansGuardian up is disabling Clamav. I'm careful and I use linux, so I choose not to use it. To do so: (at your own risk, of course)
- Log into router via ssh
vi /packetprotector/etc/dansguardian/dansguardian.conf
- Go to line 412, (415 in 2.X) and hit "i" to insert text, now type a "#" (just one pound sign) in front of/at the beginning of the entire line.
# contentscanner = '/packetprotector/etc/dansguardian/contentscanners/clamav.conf'
- Type :wq (shift+colon, then w, then q, then enter.) This returns vi to taking commands (and not editing the text anymore,) writing the changes to the file, and quitting.
- In the web interface, click on "Proxy," then "Settings."
- Click "Disabled" under content filter, then submit. Let that finish, the page should eventually reload. It will indicate that it is disabled.
- Click "Enabled" under content filter, and then hit submit. It should not take nearly as long as before, and the Eicar.org virus test files will be allowed to download, but sufficiently naughty sites still won't. Webpages will load noticeably faster, too.
To test if the filter really is running without endangering your eyes, feel free to use my test page: stupidicus.googlepages.com -- it's got a DG score of 475 since it mentions bypassing DG.
