[Solved] Lan-Only Sync For One Machine


Recommended Posts

[sOLVED] See below.


We have a setup where I use BTSync to synchronize classic folders of file updates with other members of a team. All users are trusted, but on one machine I only want to sync over LAN because of bandwidth restrictions.


My laptop is connected nightly on an unlimited internet plan, while a desktop is within a LAN on a metered connection. I download updates from an always-on server when I am home on the Laptop, and open up BTSync on both devices so that they can sync over the LAN.  


Laptop: Moves between connections. Syncs with internet and desktop.

-Windows 10

-Sync 2

-Use relay

-Use Tracker

-Use LAN.

-I use Netlimiter to programmatically minimize Internet downloading during work hours, but allow all LAN traffic for BTSync.


Desktop: Sits within a network with severe download restrictions.

-Ubuntu 14.04

-Sync 2

-Do not use Relay

-Do not use Tracker Server

-Search LAN

-Use Predefined hosts (Configured for ONLY the Laptop)

-NO pregram exists on Linux that can configure internet/LAN bandwidth per application like Netlimiter.

-Less-tech-savvy LAN users can access the folders through Samba/Windows sharing.


I configured the Desktop as above after connecting the folders, but it continues to download from Internet sources that it has "seen" before when it was still using the tracker. This effectively nullifies the "Use Predefined hosts" feature.


How do I get BTSync to forget these internet peers that it knows about and hold to the settings as configured?


A partial solution would be if BTSync allowed me to configure both LAN and WAN bandwidth limits (.1Kb for WAN, Unlim for WAN), but I would prefer that this machine forget that the outside users exist. How can I clear the cache of internet peers?


I found my part of my answer here:
