CLion: "external file changes sync may be slow" warning

Native file system watcher for Linux

Inotify requires a “watch handle” to be set for each directory it monitors.
Unfortunately, the default limit of watch handles may not be enough for reasonably sized projects.
The current limit can be verified by executing:

cat /proc/sys/fs/inotify/max_user_watches

It can be raised by adding following line to the /etc/sysctl.conf file:

fs.inotify.max_user_watches = 524288

… and issuing this command to apply the change:

sudo sysctl -p

Main principles:
- login via ssh as root (sudo) to create tun interface
- enable IP forwarding on the proxy

Note:
reverse scroll direction option in System Settings should be disabled in my case
