These scripts need to be moved in /etc/NetworkManager/dispatcher.d/ and must be executable
|
|
|
|
### 90-nft-wg-sh
|
|
Automatically toggle DNS leak protection for wireguard connections with nftables.
|
|
Adds tcp/udp rules to block outgoing traffic to dns port (53) if the outgoing interface isn't the wireguard connection.
|
|
It assumes wireguard connection names start with "wg-"
|
|

You can check for DNS leaks with [this website](https://www.dnsleaktest.com/)

Compress an image until it's below a specified target size. Output format is JPEG, regardless of the input format.
|
|
The target size can be without unit (default to bytes). Or in B, KB or MB, for bytes, kilo bytes and mega bytes (not case sensitive).

|
|
|
|
### flatten.sh
|
|

**Careful**, this operation is irreversible and manually moving back all the files to where they were supposed to be will be a pain if you flatten your home folder.
