Thanks Aurelien! I will see if I can somehow incorporate this into the
docs.
Another user was recently asking about systemd scripts (Stuart Kendrick
I believe) so this may be immediately useful to some. I've changed the
subject to help the search.
regards,
oliver.

Ahhh, "Type=forking" ... that's what I was missing. Thank you Aurelien
FWIW: here are my versions of the /etc/system/system files. Oliver, you may
want to tweak the names of the files, and their Description lines, to better
fit into your naming nomenclature.

Hi all:) I installed the latest version of netdisco a couple of days ago,
everything went fine during the installation (at least i believe so). My work
network consists of about 1500 cisco routers and switches. But when i run the
discover all command i get about 250 results. It seems like the cdp discover
doesn't work very well. Even if i use discover on a core router the cdp doesn't
move very deep into the network. Any ideas hiw to fix this? An idea to fix
this would be to run a discovery command using a seed file with a list of the
routers but since i am new to Linux i have nit idea how to write such script. :(
Thanks in advance :)
Aris

Thanks for that Oliver that has helped really well :)
What about the ME3600 getting a invalid IID when it recognises a HP5130 on
a port? as per previously what i wrote.
Also I noticed PoE outputs of ports are not showing on the 5130, im
guessing something has to be tweaked on the backend for this to show on the
HP/H3c ?
Thanks in advance.
