I've been trying for a while now to get synergy to work between an ubuntu machine and windows 7 machine, I've tried every walkthrough I can find and I still have no luck. I'm running ubuntu 11.04 and windows 7 home premium 64 bit connected to a belkin wireless router. If any more information is needed I'll be happy to post it.

Thanks in advance

A focused troubleshooting add-on that follows the suggestions from and and targets the silent failures you described for .

Start by confirming roles and the Synergy port: the machine with the keyboard must be the Synergy server, and the client should point to that server’s IP (not an ambiguous hostname). Synergy’s core listens on TCP port 24800 by default and the GUI/daemon shows the IPs the server is bound to — make sure the client uses the correct one. (help.symless.com)

Quick checks (server + client) — look for a listening server process and test the TCP path. On the server run a socket/listener check; on Windows find the PID and process; from the client test the port. Example commands:

# Linux (server): see if 24800 is listening
sudo ss -ltnp | grep 24800
# Windows (admin CMD): see PID that owns the port
netstat -ano | findstr :24800
tasklist /FI "PID eq <PID>"
# From a client: test TCP connectivity to server IP
nc -vz <server-ip> 24800
# or
telnet <server-ip> 24800

If the server isn’t listening or the connection times out, the issue is network/firewall or a binding problem. Use verbose/debug logging in Synergy to capture connection attempts. (digitalocean.com)

Router and security-suite gotchas: many home APs have “AP/client isolation” or guest modes that prevent client‑to‑client traffic on Wi‑Fi — that will make Synergy appear to do nothing even when apps open. Test by wiring one PC to the router or disabling client isolation in the AP settings. Also remember third‑party suites (Norton, etc.) can still block traffic even when Windows Firewall is off — add an explicit program/port rule or temporarily remove the suite for a test. (docs.raspap.com)

If those steps fail, try an up‑to‑date build or the active open‑source fork Barrier (same basic workflow, often easier to debug) and be sure to install/run the server with admin privileges so Synergy can bind and accept connections. Collect the Synergy/Barrier debug logs and the netstat/ss output before posting them to the project tracker — those logs show where the handshake is failing. (github.com)

Have you try contacting synergy for help or reinstall synergy. Can you access internet? If yes means there is nothing wrong with your router but something wrong with the software or your computer. Is your laptops firewall blocking the connection?

I've had no reply from synergy after emailing them a few weeks ago and posting on their forums, I've tried reinstalling synergy more times than I can remember using lots of versions, and I've turned off every single firewall I can find, and still nothing. I can access the internet fine on both computers. Every solution to similar problems I can find on the internet leads to a dead end.

So you want to use Synergy to connect with Windows 7.

Have you seen . i have never used before Synergy so i don't know how it operates.When did this happen. Have you try doing a system restore to the time when the problem has not occured?

Member Avatar for SpinalFracture

It has never worked before between these two computers so there's no point I can restore the systems to, and yes, I've seen that page, it doesn't help a lot with my problem.

How about trying Windows 7 and Windows 7. Maybe one of the OS are having problem

When you try to open Synergy, what kind of error does it show up (if any)?

I think Synergy will not work with Ubuntu anyway (looked at their homepage and got no linux name to appear). It most probably software/driver conflict in Windows 7 itself that render the software not responding

Member Avatar for SpinalFracture

It doesn't show any error messages, it opens fine on both computers but it just doesn't do what it should - that's the puzzling part. It definitely should work with ubuntu, it's in the ubuntu software repository and an ubuntu/debian version is downloadable from their website.

Sorry I've miss that Synergy do work on Linux. Thanks for telling.

Anyway I've tried to use Synergy on Ubuntu too (for testing) and it work just fine except that I used UNR to test this so it get really slow.

Tell me your Ubuntu and windows version and basic specs so I can checked whether it does have something that may conflict with synergy

For windows, download Speccy from and post it here...

Is this all from Speccy? Doesn't look it was a complete one... Please send a more detailed one...

I've checked the specs again on the homepage just to make sure, try this first

* Unplugged you internet cable and plug it again after 10 secs.
* Try using cables instead of using wireless
* Use stable version of synergy (not beta)

Maybe there's some issue with running 64-bit XP along with Ubuntu but I'm not too sure about it... I'll do some homework first on this and come back with a better solution...
