when I try to connect from a ubuntu 10.10 machine I get a error Avahi resolver failure I've also reactivated an existing bug https://bugs.launchpad.net/ubuntu/+bug/370057
the guest is a Mageia gnome DE installed from a i586 live CD I tried to connect from [ubun 10.10] the preinstalled remote desk top viewer I can connect to another ubun 10.10 on my home network with no problem
the problem was the firewall was on by default, blocking the vinagre remote desktop viewer mark as solved
Status: NEW => RESOLVEDResolution: (none) => FIXED
