  1. So, I have 3 macs and an iphone The 2 laptops and iphone sync super fast over LAN, but the Mac Pro always connects via relay server and is so slow it’s unusable. When i disable 'Use relay server' it won't connect at all. I've tried adding pre-defined hosts and that doesn't seem to help either. Could it simply be an issue with bittorrent 1.4.111, I understand that's the last version that will run on snow leopard. Any ideas? 1 x Macbook 12” (sierra 10.12.6 + resilio 2.7.2) and 1 x Macbook Air 11” (sierra 10.12.6 + resilio 2.7.2) 1 x Mac Pro (snow leopard 10.6.8 + bittorent sync 1.4.111) Router: Virgin Hub 3 Thanks in advance!!
  2. Hi! Just want your advice which way forward is the best. I have a network of some Raspberry Pi 2 running older versions of sync: BitTorrent Sync 2.3.3 (296) Yesterday I tried to upgrade 1 of these Pis with the latest armhf-version: Resilio Sync 2.5.12 (1191) The upgrade went well and initially no problems. Server was runing fine, web-gui working fine. The problems: 1. I started so see these in the logs on the Pi with the latest version: [20180223 23:48:50.549] SF[XXXX] [XXXX]: Ignoring "peers" message [20180223 23:48:50.662] SF[XXXX] [XXXX]: Ignoring "peers" message [20180223 23:48:58.540] SF[XXXX] [XXXX]: Ignoring "peers" message [20180223 23:48:59.688] SF[XXXX] [XXXX]: Ignoring "peers" message 2. My old laptop running Linux BitTorrent Sync 2.3.3 (296) started to act strange: btsync process went 100% and memory usage went to the roof. The laptop was unresponsive. The only strange thing in the log on my laptop was: [20180223 21:58:53.395] assert failed /home/jenkins/slave-root/jenkins-Build-Sync-Manually-1668/KickSocket.cpp:222 [20180223 21:58:53.396] assert failed /home/jenkins/slave-root/jenkins-Build-Sync-Manually-1668/KickSocket.cpp:222 [20180223 21:58:53.396] assert failed /home/jenkins/slave-root/jenkins-Build-Sync-Manually-1668/KickSocket.cpp:222 [20180223 21:58:53.396] assert failed /home/jenkins/slave-root/jenkins-Build-Sync-Manually-1668/KickSocket.cpp:222 Solution for now: Downgraded sync on Raspberry Pi 2 to the previous version so I could work with my old Linux laptop. Question: Should I upgrade my desktop-systems before I upgrade the Raspberry Pi servers? Which way forward in a mixed environment is the best? Thanks for a great product! Cheers!
  3. Hi everyone, I have been using Resilio Sync for quite some time now and everything worked just fine until last week when I saw there was no syncing, no peer connection. Maybe a Windows 10 Pro update caused it, maybe the router, maybe the NAS, maybe the antivirus-firewall, I don't know, not yet anyway. I am using R Sync on an Asustor NAS (apk v2.4.4.) and on several computers (v2.5.10, now updated to 2.5.12). I only have local syncing so I have so far stayed away from relay and tracker servers. However, and this is where I definitely made a mistake, last week, becoming increasingly frustrated with all of this, in order to solve the problems, I downloaded a sample/default sync.conf and double-clicked it. It has not made things any better :-). The two pictures show (1) the NAS RSync setting where (in Dutch) it says that connection settings have been overwritten by config. Port is 5556 and on another tab yet another port. The second picture (2) shows a setting on one of my computers (listening port is 8888). FYI: I have ssh-ed into the NAS and I can only find json files referring to config and yes, also includes a port setting. On the computer more or less the same things. I haven't got a clue whether all those ports should be the same and where to start. Also, I should mention that, when ticking the tracker server, syncing does work. The thing is that everyting for me is local so I would like to stay on the LAN. So, let me get to my question, and I would appreciate your help a lot!: Without reinstalling Resilio Sync on NAS and computers, can I go back from the current situation, delete/change the settings that this default sync.conf has changed? If yes, how? If no, what can I do to fix this problem? If you need any additional information, just let me know. Thanks in advance for your help! Regards Hans
  4. Hi all, I have two computers (a MacBook Pro and a Mac Mini) directly connected with a pair of 10Gbps ethernet adapters. I use the MacMini as a file server. Both computers also have another 1Gbps ethernet adapter used to access Internet and other devices in my LAN, but enabling/disabling them does not affect what I am going to describe. Resilio Sync Home (Version 2.5.6) is installed in both computers. It correctly identifies the 10Gbps link and uses it, but the max speed I am able to achieve is in between 50-70 MB/s over that link – this number reported by both Resilio UI and a network monitor app. I have LAN encryption disabled. Attached you can find the advanced config I am currently using in both machines. Obviously, the link itself is working correctly — I can share and read over 10Gbps ethernet the MacMini's SSD by using AFP or SMB3 at 450MB/s, that is SSD max speed. Any clue? Thanks! Alessandro
  5. Hi, I would like to do this thread to state the situation about speed and maybe ask a few questions to have clear answers. So, I have a reasonable semi pro setup on my LAN, carrier grade equipment + cat 5E at minimum UTP. several hosts, as NAS, LINUX servers, Xenserver, differents others hosts,... So what I obtain generally is between 30MB and 50 MB. I didn't change anything about the default settings. So the transfer are always encrypted. Since we can all agree that the max speed should be 110MB maybe there are reasons for our general speed. So I would like to ask, when the interface indicates a speed does that count the part of the encryption in it or is it the actual amount of real data transfered? if no, how much is the encryption taken on the network? what other things should we take in consideration? Since on my setup and any small company setup there would be certainly 3 or 5 hosts having all files so able to transfer every files asked, why shouldn't we be able to transfer at max speed of the LAN besides HDD problems of course which couldn't be more marginal than on a setup with several hosts?
  6. Hi, i wonder if there is a particular reason why LAN sync speed is only 1/10 of the maximum possible speed? Our LAN speed measured via SMB transfer can sustain 110 MB/s, while BTsync (2.1.1) varies between 500kb/s - 6 MB/s. Thast what i have already done: 1) disabled "disk_low_priority" 2) increased send/recv buffers from 10MB to 32MB So is BTsync designed to-be able to achieve at least 50% of a GB LAN ~50Mb/s? We often have to sync large files and only reaching 5-15% of the possible LAN speed is realy bad, even dropbox LAN sync was able to reach 10-15 MB/s. We where assuming that BTSync will "surely" beat Dropbox inside a LAN, but we struggle to understand what the problem is or maybe our initial assumption was simply wrong? Anything else i can try? thx Andy
  7. I'm having an issue where the Sync is repeatedly dropping its connection, displaying "No network connection" every few mins. Currently, I'm trying to sync a load of files to a new machine (approx 2.5TB), with a one of the machines it's syncing with being on the same network. I'm seeing speeds shoot up to 100MB/s+ and then fall down to nothing, then back up and back down again. Then I'll check back intermittently and it'll be showing "No network connection". Restarting the machine fixes the issue, or after leaving it for a while (maybe 5-10 mins) it seems to resume syncing. The machine is running on Windows 7, directly wired into the router, and the other machine is running OSX 10.10.5 and is also wired into the router. Any help would be much appreciated.
  8. Have a relatively simple setup with FreeNAS running BTSync plugin at version 2.3.8. Also running the iOS client 2.3.4. If I do the following, I cannot get the iOS device to find the FreeNAS server and start doing a camera roll backup: Configure the FreeNAS btsync plugin to disable non-LAN connections: folder_defaults.use_relay = false folder_defaults.use_tracker = false folder_defaults.use_lan_broadcase = true Enable "Camera backup" on iOS device, email myself the link. Go to browser UI for FreeNAS btsync plugin, go to cogwheel at top right corner, select "Manual connection". Paste link from email, choose storage location. btsync web UI shows added folder and shows "Pending approval". Go to iOS device and approve the connection. Observed Results: FreeNAS btsync UI shows folder with "No peers". iOS device shows "Camera backup" with "Connect to a device" notice. Expected Results: iOS device should see the folder on the FreeNAS btsync service and start backing up the items from the camera roll. Alternate Flow: If I enable relay and tracker, it starts syncing. Can this work with LAN-ONLY setup?
  9. I have had great success in the past, but am currently experiencing very slow download speed on Sync (Android) over my LAN! (6.4 kb/S max, it seems). I have one synced NAS attached via ethernet cable to router. I have 3 windows PCs synced connected via Wifi, all fully synced. In the past, I have had very good download speeds via Wifi to my android device (Dell Venue 8). I recently wanted to "reset" my sync so I erased the sdcard, uninstalled Sync, and reinstalled and reconnected Android Sync via QR code. Now my max download speed to the Android device is 6.4kB/s! Previous download speeds were up to 2MB/s. Where should I be looking to figure out where the bottleneck is?
  10. Hello, I want to sync files between my Mac and my iOS devices without touching the internet. In the Mac client there are optoins to disable relay servers, trackers and to use only the LAN. But if I use these settings, BTsync on my iPad no longer sees the Mac and vice cersa. The iOS App does not provide these settings. Is there a possibility to sync locally with iOS? Please, can anyone help me? RH
  11. Hey Guys - I've got a basic question to ask, please. I subscribe to BTSync Pro and recently reinstalled the OS (Windows 10 x64) on one of my PCs. When installing BTSync, I saw that I had the option to install it as a service so did so. I set the credentials and am able to access the WebUI via http://localhost:8888. When trying to access the same WebUI from other systems on my LAN (http://newpchostname:8888), it does not work. I looked all through the preferences, advanced preferences, and searched online to find out how (if possible) to enable LAN system access, but so far haven't had luck. So - is there a way to make BTSync for Windows installed as a service accessable from other LAN PCs? My current guess is that the binding would have to be changed, but am not 100% of the format it needs to be in for Windows. The PC it's installed on is pretty basic and just has a single ethernet NIC, bluletooth, and WiFI as adapters. Thanks!
  12. We are trying to sync two Macs across a Gigabit wired LAN. Here are the settings. Not sure why we are maxing out at 160 KB/sec?? I've tried disabling encryption-over-LAN. Any other suggestions?
  13. I've been searching for something in my network with wireshark as I'd realized that BTSync sends 8-10 multicast-packets for LAN-peer-find per second while connected via WiFi to my network. Is that a bug or a nice feature to force the users to get gigabit-switches?
  14. [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: part here: and the rest here:
  15. Hi, I have a network of ~30 Windows 8 computers that I need synced. I also have a single offsite computer that is also synced. The 30 computers connect over WiFi to a single WiFi LTE hotspot that only has about 1 GB a month. The amount of new data on these 30 computers combined is less than 1GB, however, I ran a test with three machines and even with them just sitting there overnight (no new files, no new computers added to the network) I used up about 30MB of data. I opened a network monitor on one of the machines and it says that BTSync is nearly always sending and receiving data. It's a small amount but it seems to add up. Does anyone know why so much data is being sent even when no files are being added? Is there a way to stop this? I understand something needs to be sent so that the computers can stay in sync but 30MB over ~10 hours seems like a lot! Thanks a ton! ~Ian
  16. Hi Y'all I have used BitTorrent Sync for almost a year now, and it has worked great. I have synced hundreds of gigabytes data between Windows-Linux and Linux-Linux. The speed has been extremely high, with an upload to 60 MB/S (Default settings, encrypted data etc.). However, when i recently changed to a Windows server, everything slowed down. Now I get speeds from 100 KB/s to 2 MB/s, a big difference if you have to upload 1 TB of data. My setup: Both windows Pc (8,1 and Server 2008 R2) BitTorrent Sync 1.3.109 with predefined hosts, disabled relay server and LAN for forced predefined, disk priority is set to high, no encryption, no limit on local peers, buffert size maxed to 99999 and everything manually port forwarded in Windows firewall Connected with Cat6 cables, gigabit router and computers. I tried with the latest release of Sync, the speed spiked for a minute at 120 MB/s, then dropped to the regular speed. What am I doing wrong? Appreciate ALL Help!
  17. I have a workgroup set up with BT Sync. We've noticed our internet bandwidth is getting bogged down, and after eliminating all options, we're certain it's Sync. All the computers we want to sync to are on the local network. I'm not sure how to pull this off, but is there a way to limit Sync to only the local network, and not do an outbound broadcast? Probably a stupid or naive question, but thought I'd ask. BT Sync is working perfectly for our needs, but our internet connection is shoddy, so we need to eliminate any unnecessary traffic.
  18. Does btsync automatically choose between syncing over a local network vs syncing over the internet? I have a laptop that, when on my lan, I want it to sync locally only (to conserve bandwidth), but of course it would have to sync over the internet when I'm outside of the house Will the btsync clients automatically switch over to local syncing when it detects that I'm at home and on my own network? I know theres an option to only sync locally, but wondering if this process it automated if you leave both local and public options on Secondly, is there a way for me to check/confirm whether a current sync job is happening over the local network as opposed to over the internet? Bandwidth conservation is extremely important because I'm thinking of switching over to owncloud on my NAS (to replace dropbox), but using btsync to do the actual file syncing. I would hate to have to sync that much stuff over the internet all the time and suck up so much bandwidth
  19. Hello. I just realized that my devices aren't visible over WAN! Today I went to my parents house and wanted to get a file. I loaded it up and it said I had 0 peers! That's impossible because I have a dedicated Raspberry Pi always on. I go home to see that it was on, and I didn't understand why. Now I'm sitting on my Desktop (with BTSync) and my Pi (with BT Sync) over LAN they appear on peers that are active. While over WAN they don't! It says 0 peers. I used it over 3G/4G as well as over Wifi at my parents house. Am I missing some setting? This is my current configuration: Any help would be greatly appreciated. Thank you!
  20. I've been trying to get BT Sync to transfer files quickly between machines on my LAN ever since it was first made available. But speeds have been quite erratic. Finally I found a setup that is performing well, and I just thought I'd share it. Not sure how vital these changes were: I enabled "Use predefined hosts" on both machines, set "lan_encrypt_data" to False. (Both machines) What seemed to be vital to getting speeds up: finding the right values for "recv_buf_size" and "send_buf_size". With the defaults (10/10), it kept settling at ~1 MB/s. So I tried 32/32, but the improvement was minimal. I then tried out 24/24, and the results were dramatic: I started getting 6-10 MB/s. The particular values might be specific to my setup, but with experimentation I'm sure others can find their own "butter zone" values. The main lesson I learned that applied to BT Sync buffer size was: bigger isn't always better.
  21. Hello, I have a working setup at home where 2 laptops connect through a switch would sync the files without connecting to the internet. edit : I know they synced locally because they where getting speeds of up to 20mb/s which my internet feed won't reach. I do however suspect they connected to the internet to find each other because at my corporate network I am behind multiple firewalls with IPS / IDS and all sorts of smart filters. Now they can't find each other even when they are in the same subnet with no firewalls in between them. Is there any way to let them find each other without using a tracker of some sort ?
  22. Sorry if this has been asked before. If I have a folder I want to only sync over LAN I have to run off "Use relay server" and "Use Tracker server" on both instances of bitTorrent sync? I can't have a machine that only sycs a folder when on the LAN but also have other machines that sync regardless? LAN only sync can only be enforced if both sides have those settings? Thanks
  23. Hi I use btsync in a small office with 3 peers on a 100mb/s LAN and a single peer on a separate off site backup machine at my house which is accessed over a the WAN via a 8mb/s connection (actually more like 0.2mb/s practical upload speed). We share documents locally using a synced folder, this is great and much better than dropbox because we don't have to wait for the file to upload to a server on the WAN before another user can access it. It's almost as good as having all documents accessed on a server but I can have my entire office on my laptop when I'm away. Except, sometimes, when there are a lot of files queued up for sync, a recently edited file seems to wait in a queue before it gets synced to LAN peers. This can take a long time if there are a lot of files queued to sync to the WAN peer. Is there any way I can configure btsync to prioritise syncs to fast peers over slow ones? Thanks W
  24. I'm trying to sync my "iTunes" folder between two computers on my LAN at home. Computer 1: Hackintosh HP ProBook 4530s, running Mavericks 10.9.4 Computer 2: Ancient MacBook Pro (2007 model), running Mavericks 10.9.4 The folder is about 60GB, with 11,000 or so files. In an effort to speed the sync along, I copied the source iTunes folder on Computer 1 to the destination iTunes folder on Computer 2. I then initiated a read-only share from Computer 1 to Computer 2. 14 hours ago. And it's going nowhere fast. Computer 1 says "Sending; 100%; Remaining: A few seconds". Computer 2 says "Receiving 0B/s; 14%; Remaining: A few seconds." If I click on "1 of 1 peer" in the connection listing on Computer 1, I see that 8141 files are remaining. That number will stay frozen for about three minutes. Then there will be a sudden short burst of syncing activity for about 30 seconds: 8141, 8139, 8130, 8121, 8117. STOP. Frozen again for three minutes. Does this sound familiar to anyone?? I'm getting no indication that the source computer is busy indexing. But maybe this is the case? Still.... it's been 14 hours. I've tried connecting the two computers through my router (both wirelessly, and via ethernet cable), and I've tried a direct APIPA ethernet connection (169.254.x.x). In all cases, the behaviour is the same. On both machines I've toggled the following options, separately, with no luck:| GLOBAL OPTIONS: disk_low_priority -> Changed to FALSE folder_defaults.use_relay -> Changed to FALSE folder_defaults.use_tracker -> Changed to FALSE lan_encrypt_data -> Changed to FALSE TRANSFER-SPECIFIC OPTIONS: "Use relay server when required" "Use tracker server" Thanks for any help or advice.
  25. Is Peer Exchange enabled in Bittorrent Sync ? I would like selective file sync between Multiple PC on a same Lan network without requiring Intertnet.
