Hello,

I installed Hudson deamon on one server (running on debian lenny testing) some time ago. All was working until I perform an upgrade. At this time Hudson isn't accessible at port 8080 (which is the default port used). I have looked for iptables problems, however port 8080 is open in INPUT and OUTPUT. Configuration file in /etc/default/hudson seems okay, I haven't touch it. And if I do a ps aux | grep hudson, hudson deamon is running.

Update 1: What is really strange for me is that in /var/log/hudson/hudson.log I get no error :

Update 2:

What I get with lsof -i -n -P | grep hudson:

java      28985      hudson   97u  IPv6 2002707      0t0  TCP *:8080 (LISTEN)
java      28985      hudson   99u  IPv6 2002708      0t0  TCP *:8009 (LISTEN)

java      28985      hudson  150u  IPv6 2002712      0t0  UDP *:33848 

I don't know what I can verify. Does someone has an idea in order to help me to resolve this problem ?
