March 2015

# linux
synergys -f --config ~/.synergy.conf

# windows
telnet 24800

I switched off the Firewall and it still doesn’t connect:

CD c:\Program Files\Synergy
synergyc.exe -f -d DEBUG2


Had similar issues to March (see above). Finally solved the problem, by opening the firewall port:

ufw allow 24800/tcp

To see the firewall status:

ufw status

To view the firewall log (where I found the problem):

tail -f /var/log/ufw.log
