The script /etc/init.d/SABnzbd contains :
nc -z $host $port ...
For some reason, the -z option appears to have been dropped from nc
Running the command interactively returns :
glaw@fedora home $ sudo nc -z 192.168.1.6 8082
nc: invalid option -- 'z'
Ncat: Try `--help' or man(1) ncat for more information, usage options and help. QUITTING.
This is in the following package :
glaw@fedora home $ rpm -qf `which nc`
nmap-ncat-6.40-2.fc19.x86_64
One work around that I found uses tcping instead :
I have replaced the nc line with this one :
/usr/bin/tcping -t 1 $host $port &> /dev/null
Hope this helps someone
