I've never actually been able to get Synergy working, even when using QuickSynergy. Even using this guide gives me nothing; my mouse won't leave the edge of my screen. I've even disabled both computers' ufw firewalls to make sure ports aren't being blocked. What am I doing wrong?

work-macbook, host computer:




work-laptop, slave computer:



Pinging work-macbook from work-laptop works, and pinging work-laptop from work-macbook works. Things are basically working with host-names to IP addresses on my network, so that doesn't seem like the issue:


work-macbook $ ping work-laptop
64 bytes from work-laptop (

work-laptop $ ping work-macbook
64 bytes from work-macbook (

Done, sorry about that. – Naftuli Tzvi Kay Jan 2 '12 at 23:54
Have you tried using the IP addresses in the config file for hostname and clientname? – Kendor Jan 3 '12 at 0:47
@Kendor Yes I have. Really weird. – Naftuli Tzvi Kay Jan 3 '12 at 1:56

Have you tried setting up your config file on the host as shown in the synergy docs?

Name the text file ".synergy.conf" in your host home folder.

Something like this:

section: screens

section: links
        left =      work-laptop
        right =     work-macbook

Then run "synergys" on the host and I believe it's "synergyc -a [address]" on the client. You can run synergyc with the -f option to make it run in the foreground, that might tell you something about why it's not working.

Evidently, there was a DNS issue, but this conf fixed it and things are working GREAT now. Thanks! I had to run synergyc IPADDRESS – Naftuli Tzvi Kay Jan 3 '12 at 17:42
