[FreeNX-kNX] Problems with Fedora 10 & qtnx

Tue Dec 16 19:28:54 UTC 2008

stracing qtnx gave me nothing. However I tried what is suggested here:

http://openfacts2.berlios.de/wikien/index.php/BerliosProject:FreeNX_-_FAQ/Server#Identity%20file%20id.key%20not%20accessible

I am attaching the log below, however the following lines are
interesting:

Failed publickey for nx from 127.0.0.1 port 45031 ssh2
debug3: mm_answer_keyallowed: key 0xb9e62130 is not allowed

I am not sure why this fails. I can still log with:
ssh -i /etc/nxserver/client.id_dsa.key nx at localhost

Here is the log from ssh.
Kind regards:
