Subject: Make pinging hosts configurable
X-Git-Url: https://git.llucax.com/software/bacap.git/commitdiff_plain/93cf7cf99a72cc9a6af670e846b479c37e07c2ac

Make pinging hosts configurable

Add a new configuration option to choose whether remote hosts should be
pinged to check if they are up or not. Disabling this option is useful if
your remote hosts don't reply to ICMP pings for security reasons.
