Synergy IS simply wonderful. I have used it for over a year and after replacing one machine received the error. The IP address worked instantly. Thank you for posting!

I have been using synergy for several months now and I must say it is awesome. I use it along with a kvm because I use dual display for one of the machines. However just today I could not get them to reconnect so I did as described above and instantly I am up and running again.

Thanks!

I had exactly the same problem, after a period of unreliability from Synergy. It seemed to have acquired a mind of its own. Had it running with one PC with two monitors and a second with one monitor and it originally worked seamlessly over the three screens with no problem but the program started working intermittently and then suddenly decided to give up completely, only displaying the green circle icon without the “lightning” connected symbol in the middle, together with the “Synergy 1.3.1 – WARNING: failed to connect to server: Timed Out” error on the client PC. I tried re-installing but no joy. The cure given by “john” worked instantly, although I did have an instance of a jerky cursor on the client screen only afterwards, (something I`ve seen before), which seemed to be cured by a reboot. Anyone know what`s going on here and does the author know? I did post on the Source Forge Synergy help forum, but had no responses. I will probably post the answer there for anyone in the same boat.

Ah, yes, but surely that begs the question as to why it worked quite happily in the previous configuration (i.e.name and not IP address) for the best part of a year before deciding not to work. Why does the server PC also not need that modification? My set-up is now working quite happily with a mix-and-match. If it ain`t broke, don`t fix it – I shall leave well enough alone Regards to all.

Hope there is someone at the other end of this to solve my problem. Think I have hooked up the computers properly but it does not work. The server says
FATAL: failed to startserver: cannot bind address: WSAEINVAL. The client says WARNING: failed to connect to server: address not found for: Michael. Anyone able to diagnose and solve this issue? It would be greatly appreciated. Thanks.

if you have tried the above and are still havening problems make sure to disable windows firewall or route thru tcp and udp port 24800 (that worked for me)

My server won’t start. Get the following:

FATAL: failed to start server: cannot bind address: The specified address is not available from the local machine

This is Win XP (Pro), had it working, shut off both computers, came back 4 hours later and started back up and can’t connect with this error.

I tried using IP addresses for screen names, tried changing ports from 24800 to 24900 on BOTH server and client. Rebooted both machines. Still no change in error message. Any ideas?

thanks for this tip. I was fighting it all day after a upgrade to SnowLeopard and Win7 simply refused to co-operate.

Thanks to you and to the creators of Synergy! You’re awesome. Couldn’t get synergy to work after reinstalling xp. This solved the problem.

I can not get the client to connect. have tried both the host name and IP address for the server but still get “ERROR: Failed to connect to server: Timed out” Any help would be greatly appreciated.

Thanks for this tip – I had had Synergy running rock solid with one laptop but when work upgraded me I COULD NOT get it to work, and the support on the Synergy Forums was no help. This did the trick in short order.

Thanks a ton ! I have been using synergy for quite some time, and this error showed up right when I was at the peak of frustration due to many such config issues I Was dealing with, You saved my day, truly !!.

I tried all the above mixed with restarts with no success. I eventually just uninstalled and reinstalled, and it works again!

Thanks for posting this!!

I got this error after updating from Tiger to Leopard although the computer name didn’t change. Using the IP fixed the problem.

And I just could not have lived without Syngery anymore

Thanks for those hints!
I’m running XP on the server side and Vista on the client side. First synergy worked without problems but from time to time I’m not able to connect both PCs at all, even when using the server IP directly. I also disabled my XP firewalls and checked for the correct port forwarding on my router. I’m just not getting why it does not work…

Thanks for this post. You saved me quite a bit of time.

I had Synergy working with my old laptop, but when I got my new one, using the machine name on my desktop was no longer working to reach the new laptop. Once I entered the IP address of the new laptop, bam!, Synergy was able to make the connection and everything is working fine now.

You rock, John!

I have been going out of my mind trying to get synergy to work on my company computers following a re-image. I almost gave up until I found this site. This worked perfectly. Thank you so much!!!!

Thank You!

This fix worked great for me. I have used Synergy for about half a year, then all of the sudden I got this error. A few pokes and prods after reading this fix, and she’s alive!! Thank You again

Thank you, that sucked big time.
Why did it happen and how does it degrade over time?

Hey, great fix. I’ve struggled getting connections on and off for a long time. Usually after I have to re-boot one of the machines.

I love Synergy. Maybe even more now if it will keep connecting.

Doesn’t seem to be much ongoing development or support for this tool anymore though. Is that right?

Great fix dude! Well done. Mine wouldn’t connect this morning. Kept showing timeout error. Played with firewalls on PCs and routers but no joy. Googled the problem – came here and your fix worked instantly.

Well done.

PS: I echo everyone’s love for this software. Synergy rocks!

Synergy really is great. I hope that the developers will soon implement some type of drag n drop feature between pc’s. Replacing the client pc’s server name with the server ip worked instantly for me, thanks a lot. I found this post extremely useful. ;]

Dylen.

Synergy is the best. I have a small computer under my livingroom 50″ TV with my laptop on the coffee table all the time. I rarely go to real TV and end up surffing Netflix and Hulu for the next show or movie I intend to watch. I don’t have to buy any of those TV boxes. I have full control right from my coffee table. Best value component for home theater.

Thanks for the tip! This worked great — now I’m no longer getting the server time out message and the lightening bolt is present on both the server and the client; however my mouse won’t move off the server. Anyone have any suggestions? Much appreciate any help you can offer!

I have three XP machines to connect to Synergy. A & B (server) work fine – can’t get C to connect. All the settings in C are the same as A. Have disabled firewall etc – but C gives the message “connecting to “B” :[IP Add] failed to connect to server: cannot connect socket: The requested address is a broadcast address, but the appropriate flag was not set. Can’t seem to resolve this. As A & C are very similar machines with identical setup they should both connect ok. Any suggestions would be appreciated.

I would first check you are connecting to the IP of the server machine from C.

Thanks John. I am connected because can see the server name and IP address in the error message returned on C. I have since diagnosed the problem – found it was Macafee services running on C. Macafee was not running, but had loaded three background processes which were blocking requests. Once they were disabled, everything worked. fine.

Excellent. I’ve been using synergy with 5 screens on 3 computers for about 2 years now. But, all of a sudden this error appeared. Don’t know why and don’t care because the IP address worked perfect.

Thanks a lot.

I have a love/hate relationship with Synergy. I’m running a Mac all-the-time, and windows boxes come and go. Whenever a new Win box is introduced to the network, the first thing I do is install Synergy. Oddly, it only works some of the time. It gives no errors on either the Win or Mac, but it just doesn’t fully connect. I can ping just fine, if I change something in the setup on either errors start flying, but when it’s set up properly, only some Windows machines connect.

Any ideas out there would be much appreciated.

This may not be possible if you’re running a large network, but you may want to give each PC a static IP instead of using DHCP. Then change the configuration in Synergy to connect to those IPs instead of the machine’s name.

DHCP may be issuing those PCs a new IP when they restart/boot up which could be causing your issues.

Please let us know if this works for you.

Just sharing in case someone needs it

I had a small issue, I have a dual boot (Win7 / Fedora14) laptop and a netbook (XP) being the dual boot the server, I could connect the client to the Win7 server, but not to the Fedora server… so I Add the port to the Firewall to grant the access… that fixed my problem!

I hope this helps to some or all of you.
Thanks!

easy fix is to enter your host server ip on client comp in the space on the bottom of the main interface titled ” Name of the server”

note this applies to the 1.4.2 version

I had also the same Problem.
The Server messaged “Waiting for Clients”
The Client messaged “Failed to connect”
But a few time before is was working well.
I replaced the Hostnames into the IP Adresses and suddenly it runs.

Setup:
2 Win XP PCs Servicepack 3
Synergy added to the Firewall on both Computers
Every PC has his own Hostname and static IP

Thanks to all for the Help!
