|
||
* Rules are automatically apply only for the UP interfaces.
|
||
* If it's detect some softwares (eg. Apache2), Iptables rules for ports 80/443 are automatically apply.
|
||
* Special rules allow all traffic throught a VPN:
|
||
```sh
|
||

* If a local file exists (firewall.local) it will also apply it. For personnal rules for example.
|
||
|
||

||
Convert FLAC audio files to MP3 with 'avconv'.
|

⑱
|
||
```
|
||
|
||
### Pomodoro
|
||
My implementation of the Pomodoro Technique (https://en.wikipedia.org/wiki/Pomodoro_Technique).
|
||
|
||
You can simply launch it with:
|
||
```sh
|
||
pomodoro "Work my french kiss"
|
||
```
|
||
|
||
Then the script will:
|
||
* Create a ~/.pomodoro directory to store current task (current.task) and a summary of each week (eg week-42-2015.txt).
|
||
* First, it's put task name and a timer (for $WORK_TIME) to the current task file.
|
||
* Once the $WORK_TIME has been reached:
|
||
1. Log task name and worked time to the weekly log file
|
||
2. Toggle the sound to mark a pause
|
||
3. It's put a pause/break message for 5/20 minutes as current task
|
||
4. Delete the current task file
|
||
|
||
#### Disavantages
|
||
* Must run the script every ~30 minutes
|
||
* …?
|
||
|
||
#### Advantages
|
||
* I can display my current task and it's timer wherever i want (tmux, herbstluftwm, …)
|
||
* Written to work with /bin/sh
|
||
|
||
## rename_meurice_podcast
|
||
I download some podcast from a RSS flux (http://www.franceinter.fr/emission-le-moment-meurice) but i don't like :
|
||
* the filename
|
||
* the title tag
|
||
|
||
So it's a tiny script to correct this. I get the date and the "real" title from the "title" tag and :
|
||
* The filename become "$date_$realtitle.mp3"
|
||
* The title tag become "$date_$realtitle"
|
||
|
||
"Le moment Meurice" : http://www.franceinter.fr/emission-le-moment-meurice
|
||
|
||
The script manage both a directory and a file as first argument.
|
||
|
||
## tag_photo.sh
|
||
The main goal is to have a solution to know the "subject" of a picture without to open it and no really good name. It can happen if you delete your pictures and get it back with `photorec` or `foremost`. For this i use the Exif metadata.
|
||
|
||
You can simply launch the script with your pictures directory :
|
||
|
||
``` sh
|
||
tag_photo.sh /tmp/Images
|
||
```
|
||
|
||
Then the script will :
|
||
* List all subdirectories.
|
||
* Get the basename of each directory and add it as the value of the Exif "description" tag for each images.
|
||
|
||
To see the result, you can display the tags "File Name" and "Description" of you images :
|
||
|
||
```sh
|
||
find /tmp/Images -type f -iregex '.*\.\(jpg\|gif\|png\|jpeg\)$' -exec exiftool {} -FileName -Description \;
|
||
```
|
||
|
||
## Test_ssl3
|
||
Redhat's script to test if an LDAP server support SSLv3.
|
||
|
||
You could also use a nmap command:
|
||
```sh
|
||
nmap --script ssl-enum-ciphers -p 443 ldap.tld.org | grep "SSLv3: No supported ciphers found"
|
||
```
|
||
|
||
## Weblink
|
||
Python program that run a small webserver (BaseHTTPServer) to easily share some files.
|
||
* eg:
|
||
```sh
|
||
weblink /tmp/goodbye.file
|
||
HTTP server running at http://localhost:8888/
|
||
^C^C received, shutting down server
|
||
```
|
||
* With a password:
|
||
```sh
|
||
weblink --pass=die /tmp/kitty.file
|
||
HTTP server running at http://localhost:8888/die
|
||
```
|
||
|
||
## Winboot
|
||
Tiny script to reboot the system to a windaube partition.
|
||
|
||
Be sure to set the correct value to **WIN_GRUB** variable which must be the number of the windoze partition in Grub. Be careful, the grub's entries start at 0.
|
||
|
||
* The script will also modify the grub configuration :
|
||
* Set Grub in "saved" mode.
|
||
* Ensure to set the previous default entry with `grub-set-default`.
|
||
* Then for the reboot :
|
||
* Choose the grub entry for the next reboot.
|
||
* Reboot the system with ``systemctl``.
