[FreeNX-kNX] FreeNX & SuSE 9.3 (SOLVED)

[Alexander Rettig]

Hi Folks,

first of all, thanks for NX/FreeNX. I just was in trouble with FreeNX/kNX and found out that *if* you want to play with keys you have to do it a little different to get kNX running:

After performing on the designated NX-server machine, e.g. mynxserver, 

nxsetup --install --clean --purge

you have to copy the generated key to the directory on all NX-client hosts, where kNX looks for the key; I'd propose to do the following steps on all machines as root, where the kNX-client should run:

# keep a copy in case you want to switch back to the NoMachine-key
mv /usr/share/knx/client.id_dsa.key /usr/share/knx/client.id_dsa.key.org
# copy the generated key
scp root at mynxserver:/var/lib/nxserver/home/.ssh/client.id_dsa.key /usr/share/knx/client.id_dsa.key
# make sure it has the same permissions as the original kNX-key
chmod --reference=/usr/share/knx/client.id_dsa.key.org /usr/share/knx/client.id_dsa.key

Big disadvantage of this solution: you won't be able to connect to any NX-Server, which uses a different key, including all servers configured with --setup-nomachine-key.

This leads to a question (any kNX-developers here?) - is there a chance to store several client-keys to be used by kNX thus enabling you to connect to several servers which use different keys? If not, what do you think about it, hard to implement?

Hope it helps, and - if you have a working solution already, better ignore this mail ;-)

PS: be aware: this holds for SuSE 9.3. If you use another distribution you may have to find out where kNX looks for it's client-key.
