Comment 3 for bug 318301

I followed your instructions and entered

sudo /usr/share/webcontentcontrol/scripts/export_all.sh "/usr/share/webcontentcontrol/backup"

into terminal.

Then I entered:

sudo apt-get remove --purge firehol tinyproxy dansguardian

and it appears to have removed all the software (checking for firehol, tinyproxy and dansguardian in synaptic package manager confirms the software is no longer installed).

However, I am still unable to vnc from my laptop into my PC over my local network. I'm not sure what to do about this.
