It looks like OpenSSH Keys generated on Debian derived distros (Ubuntu/Voyage etc.) are REALLY bad. I’m currently rolling out OpenSSL key updates as adviced on http://wiki.debian.org/SSLkeys.
One casualty of this update was my NX server using freenx. It just tells me that I can’t be authenticated. In the log /var/log/freenx.log it shows the following:
– NX SERVER START: -c /usr/lib/nx/nxserver - ORIG_COMMAND=
HELLO NXSERVER - Version 2.1.0-71 OS (GPL)
NX> 105 hello NXCLIENT - Version 2.1.0
NX> 134 Accepted protocol: 2.1.0
NX> 105 SET SHELL_MODE SHELL
NX> 105 SET AUTH_MODE PASSWORD
NX> 105 login
NX> 101 User: shuerlimann
NX> 102 Password:
NX> 404 ERROR: wrong password or login
NX> 999 Bye
This post talks about the NoMachine NX Server, but gave me the necessary clues: http://lists.kde.org/?l=freenx-knx&m=116542288527396&w=2
The magic command for freenx from http://datakeylive.com
on Ubuntu is
sudo rm /var/lib/nxserver/home/.ssh/known_hosts
This is necessary, as the SSH host key has been updated… Well, a more informative error message would’ve been nice, but I’m thankfull to the guys who produce freenx, anyway

You can setup syslog to connect to the relay. In this release, we only support syslog over UDP. To set this up, you need to modify your syslogd config file. Often this is in /etc/syslog.conf
To get started, you can add
. @relayMachineName:4657
This will send all your syslog messages to a machine named relayMachineName over port 4657. Port 4657 is the default port the relay listens to for Syslog UDP messages. You can change this in the relay’s property file. This properties file is located in the ‘conf’ directory of your relay installation (e.g. /opt/sourcelabs/relay/conf).
To filter the syslog messages sent to the relay, please read the syslog documentation or man pages for more information.
Syslog-ng:
You can also setup syslog-ng to use the relay. For the current version of the relay, you will need to use UDP logging to the relay instead of TCP. To set this up, you need to modify your syslog-ng config file. Often this is in /etc/syslog-ng.conf
To get started, you can add
destination d_relay { udp("relayMachineName ", port(4657)); };
log { source(s_sys); destination(d_relay); };
Assuming that you are using a default syslog-ng configuration where source ‘s_sys’ represents all syslog messages (modify source as necessary for your configuration),this will send all your syslog messages to a machine named relayMachineName over port 4657. Port 4657 is the default port the relay listens to for Syslog UDP messages. You can change this in the relay’s property file. This properties file is located in the ‘conf’ directory of your relay installation (e.g. /opt/sourcelabs/relay/conf).
To filter the syslog messages sent to the relay, please read the syslog documentation or man pages for more information.
