What does lsboxd process do on os x? My firewall asked me for a connection from lsboxd (module com.apple.ls.boxd, ) to one another computer in my network to the port tcp 548. What does it do? I found that it is a part of sandbox technology of a OS X, but what is it more specifically? I found it in my launchctl list output:

com.apple.LaunchServices.lsboxd
lsboxd is part of the OS X Sandbox.

It allows communication between sandboxed applications.

lsboxd is in the Launch Services API. It is the Launch Services Sandbox Daemon, which governs what apps can launch apps in the OS X sandbox. You can peruse the App Sandbox Guide for more information about sandboxing.
