after struggling with google talk plugin and chrome on fc18 (hint: Warning(clientchannel.cc:562): Connection lost while waiting for authorization reason=0 in chrome logs ), eventually found out that the culprit was firewalld …
systemctl stop firewalld
fixed that :).
And to disable it completely also for next boots, just
systemctl disable firewalld
Obviously systemctl must be called as root.
Afterall I have a router with firewall on home network, I don’t need any firewall on my local workstations
