stopped by renaming? Sounds problematic, stop it explicitly, and make sure it won't get restarted. Renaming/ removing symlinks under /etc/rc*.d on Debian is strongly discouraged. use update-rc.d for this task, first remove the existing links, and then recreate them as K... ones. Otherwise the next package upgrade might reenable the daemon.
I recreate them as K... ones now, and syslog-ng give me the same Error Message. I tried to stop them with rcconf, it say they will be not started, but syslog-ng can't start
You might also want to try removing the default syslog package. On Ubuntu this is done with: sudo apt-get remove sysklogd
I removed it just after installing syslog-ng, so i don't know what is the problem. Why syslog-ng don't start? I think maybe I configured something wrong, but i can't they what... thank you for your answers Patrick
