i never did write a grumble post about the debian ssl exploit (great explanation of the issue and some motivational posters) and i’m still finding issues because of the new keys. the lastest issue i was trying to debug why i wasn’t able to connect to one of my boxes via nxclient. checking around in the logs i saw, “Offending key in /usr/NX/home/nx/.ssh/known_hosts”… simple enough.

after looking at that file and comparing it to /etc/ssh/ssh_host_rsa_key and /etc/ssh/ssh_host_rsa_key.broken i drop in the new keys and nxclient connects just fine. i would also recommend regenerating your personal keys if you use an authorized_keys[2] file

update (05/05/08)
i guess a lot of people are looking for mythbuntu + nxserver because this post is getting tons of search traffic. one thing that bugged me forever about mythbuntu + nxserver/nxclient was trying to get xfce or even kde4 to start. to make your life easier if you can spare the space, install ubuntu-desktop (#) in mythbuntu to use nxclient like you normally would on a ubuntu desktop.

i’ve really gotten used to using nxclient to connect to my linux server vs vnc. it’s about as simple to setup nxclient as it is to setup passworded X11 vnc, but nxserver uses encryption (ssh) out of the box. vnc doesn’t. you can also disconnect from a nx session and reconnect later, almost like screen but for X11 and not just a console.

how to install nxserver on (mythb)ubuntu 8.10

1. download the nxclient, nxnode, and nxserver debs from nomachine. [here]
2. install the packages w/ `sudo dpkg -i nx*.deb`
3. ssh to your server from your client
   to make sure your keys are setup properly. ssh w/ authorized_keys is optional, nxclient will remember your password if you want.
4. connect to your server using an nxclient for your client machine. [here]
