Ubiquiti router disable WAN access to GUI

If you do not plan to change settings on your ubiquiti router remotely it is a recommended security measure to disable SSH and graphical interface (GUI) access from the Internet. By default anyone that knows your public IP can try to log-in using the GUI or SSH.

The commands to disable the above as as follows:

configure
set service gui listen-address 192.168.0.1
set service ssh listen-address 192.168.0.1
commit
save
exit

(192.168.0.1 is the default gateway, if you LAN gateway is not 192.168.0.1, you should change the IP to match your LAN gateway IP).

It is also possible to disable SSH completely from the GUI. Click on system tab and un-check ssh access. This will block SSH completely wont work even from your LAN, , only the GUI will remain accessible.

Text file recovery after deleting or quick formatting

If you deleted  a text file or you made a quick format that erased an important text file, first of all, if it is your boot disk do not boot from it again as it may overwrite the sectors where the lost data is stored and now marked empty. If it is not a boot disk, do not write any new data to the disk.

If you followed the recommendations above, there is a good change the data can be recovered. Usually you would like to use Photorec from another computer or from a live Linux CD and save the recovered files to another disk.

However if the text file did not have an extension (text files created with gedit do not have extensions by default), you will not be able to use Photorec. In that case you may try the command bellow from a live Linux CD or from another linux machine.

sudo grep –binary-files=text -C 1000 ‘tex string on the deleted file’ /dev/sdX1 > outfile.txt

You just need to remember a word that was in the text file you are trying to recover. It should be a word that does not come up on any other text file. Then edit /dev/sdX1 and change sdX1 with the correct path to the disk where the erased text is.

Good luck with the recovery! If this text was useful, please do not forget to link to this blog.
