x2go is a remote desktop server and client package, partly based on the nx program, but not compatible. Yet there are package repositories for all valuable distributions.
Following this guide, add their debian repository.
# apt-key adv --recv-keys --keyserver keys.gnupg.net E1F958385BFE2B6E
# vim /etc/apt/sources.list.d/x2go.list # X2Go Repository deb http://packages.x2go.org/debian squeeze main # X2Go Repository (sources) deb-src http://packages.x2go.org/debian squeeze main
# apt-get update # apt-get install x2go-keyring # apt-get update
Install the server, plus the xsession package if you already got a desktop environment running (like me having KDE running).
# apt-get install x2goserver x2goserver-xsession
x2go uses the nxclient libs, which requires sort of a local proxy for ssh, listening on port 30001. This must be enabled in your firewall, otherwise you will get messages in syslog like this
sshd connect_to localhost port 30001: failed
Create an entry in your iptables filter and reload it.
# x2go -A INPUT -p tcp -m tcp -s 127.0.0.1/32 --dport 30001 -j ACCEPT -A INPUT -p tcp -m tcp -s 127.0.0.1/32 --dport 30002 -j ACCEPT -A INPUT -p tcp -m tcp -s 127.0.0.1/32 --dport 30003 -j ACCEPT
Using ssh keys for authentication is rather tricky, and got a lot of session errors. So if you run into that, leave it – bug hell.
