Apt-caching server in Linux : apt-cacher-ng
In this video, I have demonstrated how to set up apt-cacher-ng for host and client machines.
Apt-caching is a way to cache apt packages and repos on a cache-server and then distribute them much more faster on LAN systems.
Host commands:
1. Installation and start
sudo apt install apt-cacher-ng
sudo systemctl start apt-cacher-ng
sudo systemctl enable apt-cacher-ng
sudo systemctl status apt-cacher-ng
2. Allow HTTPS packages
sudo nano /etc/apt-cacher-ng/acng.conf
... In this file, Uncomment line "PassThroughPattern .*"
... And then save the file ... Ctrl+X ... Y ... Enter
sudo systemctl restart apt-cacher-ng
3. Set up firewall to allow traffic through port 3142
sudo ufw allow 3142
4. Additionally, for allowing auto configuration on clients
sudo apt install avahi-daemon
Client commands
1. Auto configuration
sudo apt install auto-apt-proxy
.... you might need to restart system
OR
2. Manual configuration
.... write one line to 00aptproxy file ... either do (a) or (b).. both are similar
(a) sudo echo "Acquire::http::Proxy \"http://SERVERIP:3142\";" [right angled bracket] /etc/apt/apt.conf.d/00aptproxy
(b) sudo nano /etc/apt/apt.conf.d/00aptproxy
..... In this file, write:
Acquire::http::Proxy "http://SERVERIP:3142";
..... Then save the file ... Ctrl+X ... Y ... Enter
Seeing live logs on Host system
tail [hyphen]f /var/log/apt-cacher-ng/apt-cacher.log
Web interface for report and clearing cache and few other stuff
In browser go to:
http://SERVERIP:3142/acng-report.html
... If you are on host system only, you can replace SERVERIP with localhost
