+# NGINX ALLOW DYNAMIC IP
+## Configure nginx config files to edit IP based on domain name
+
+
+### Requirements
+`dig` \
+dig is most likely installed on your distro but incase it isn't install it first
+
+### Usage
+First, get the script and make it executable:
+
+```bash
+curl -O https://git.shihaam.dev/shihaam/sarmic/raw/branch/master/nginx-allow-dynamicip/nginx-allow-dynamicip.sh
+chmod +x nginx-allow-dynamicip.sh
+```
+Make sure your nginx config server block contain "#DYNAMIC" after the IP you want to change dynamically\
+Something like the following:
+```nginx
+        #Block public access
+        allow 1.1.1.1; #DYNAMIC
+        deny   all;
+```
+Excute the script as root (or with sudo) with 1st argument for config file and 2nd argument with domain of the IP you want to allow \
+`sudo ./nginx-allow-dynamicip.sh db-sarlinode.shihaam.dev home.shihaam.me`
+
+### Automate with cron
+Run `crontab -e` as root as this script needs to edit nginx config file and restart nginx
+```bash
+sudo crontab -e
+```
+I have it configured to update once every hour like this
+```bash
+0 * * * * /home/shihaam/scripts/nginx-allow-dynamicip.sh freezer.shihaam.me home.shihaam.me
+```
+### Notes
+It is important that your nginx config files are in `/etc/nginx/sites-available/` and symlinked to `/etc/nginx/sites-enabled/`,\
+This is done by default on Debian and Ubuntu, I noticed this is not how it's configured by default on Arch Linux and CentOS, If you're using those you have bigger issues. Tested and verifed to work on Debian Linux.

+# Use another device as an auxiliary display for a xorg GNU/Linux
+With x11vnc, you can use your another device as a display that extends or mirrors your xorg GNU/Linux desktop.
