Post-installation

Start FreeSWITCH service

systemctl start freeswitch
systemctl enable freeswitch

check if it is running

ps aux | grep freeswitch

DNS cashing

By default, Debian has no DNS caching and every lookup goes to the server from /etc/resolv.conf. Unbound is a light, secure, and easy to use DNS caching server.

apt -y install unbound
systemctl start unbound
systemctl enable unbound

Proper entropy source

Most Debian systems may not have sufficient entropy for proper cryptography operations. Haveged is a userspace entropy daemon that is not dependent upon the standard mechanisms for harvesting randomness for the system entropy pool.

apt -y install haveged
systemctl start haveged
systemctl enable haveged

Automatic time synchronization

Chrony is a fast, secure, and easy-to-use time synchronization daemon.

apt -y install chrony   # installation
systemctl start chrony  # start
systemctl enable chrony # auto start
