IDN Safe blocks internationalized domain names also known as punycode domains. This helps you to identify them and will prevent you from visiting probable fake sites.

The use of Unicode in domain names makes it potentially easier to spoof web sites as the visual representation of an IDN string in a web browser may make a spoof site appear indistinguishable to the legitimate site being spoofed, depending on the font used.

With IDN Safe you can temporarily allow domains or whitelist them at all. By default they are blocked.

You can find it on the PlayStore.

This app shows your current IP address and geolocational information about it.

It also notifies you, if you have a broken VPN or proxy connection, when the country-code and/or IP address changes unexpectedly. You can set an alert with a special ringtone and or vibration.

You can also display your IP position in Google Maps or check for DNS leaks via browser (external service).

Please note, that the information about your location are fetched out of a database and may not be the same as your real location. This app shows your location like the websites would match your IP to any location.


Get it on Google Play

Fail2ban and owncloud are great tools!

To improve your security, you can ban bad guys, who want to hijack your owncloud accounts with random but common credentials, easily with fail2ban and the specific configuration for owncloud.

To make this as easy as possible for you, I wrote a shell script, which will setup everything with just one line:

curl -s "https://raw.githubusercontent.com/AykutCevik/owncloud-fail2ban/master/automated-install/install.sh" | bash

You can also use this command to update the regular expression for fail2ban, when a new version of owncloud is released. The script will check your installation and will update it automatically.

There is no black magic. Feel free to contribute and taking a look at the code at github.

The script has been tested with owncloud 9.0 & 9.1 and Ubuntu, but may also run under other versions and distributions. If not, please let me know.

For older versions (8.2, 8.1 & 8.0) of owncloud check out the github repo.
