Maintenance

disk check for bad-blocks

e2fsck -c /dev/fill-me -c invokes badblocks internally. badblocks manual recommends this method rather than using badblocks command separately and feeding it to e2fsck -- CAUTION! block size. Note: ubuntu checks file systems periodically, but doesn't check for badblocks probably.

For /home, reboot in recovery mode and run e2fsck

Troubleshoot

Printer prints blank pages till paper runs out

Settings, Printer, make & model -> change Choose the same Manufacturer, Same model, but try a different foomatic driver shown in the list.

WebRTC and ip address leaks

Try:

• Enable a vpn
• visit https://ipleak.net

Other "what is my ip" kind of sites show only one ip address, but ipleak.net shows ip address obtained through various means. From this it is apparent that firefox leaks ip address through WebRTC.

Also verify with https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/ (click gather candidates)
