Maybe a formatting glitch in your email but it looks like there's a
space between "-d" in the command?

Hi:)
I tried the script line you mentioned in your answer but no luck.
Maybe i am doing something wrong? I made a txt file that includes a
list of all the router names (one name per line as you suggested:))
but i get the following error message: bad host, ip or prefix: (name
of router). Same thing happens if i use ip addresses. So it's
definitely not a dns resolve problem.
Here is the complete command i am using : while read routername; do
~/bin/netdisco-do discover - d $routername; done < db.txt
A tiny little help would be appreciated :)

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

Hi Pavel,
Thanks for your reply:) yes the file is definitely there and there is only one
hostname per line. I did run "cat db.txt" and everything seems in order. The
first name on the txt file is dsager1 and the full error message is: info
discover error - bad host, ip or prefix: dsager1. And then it goes on for the
rest of the names. So the command does run for each name in the list but for
some reason the name is not recognized

Screaming tree(s),
Check if that db.txt really exists there and has the right formatting (one
ip/hostname) per line. Do "cat db.txt" it should print out the content of the
file.

Pavel

Ah, okay this may be a local host DNS configuration issue (that is, not
within Netdisco).
Is there a DNS server in /etc/resolv.conf ?
I would first try adding your domain name to the end of the host name,
such as dsager1.example.com. If you come from a Windows world you may be
used to expressing host names in an unqualified form, but in Linux it's
more common to express them fully qualified (that is, with the domain
name added).

oliver.

I don't think it's a dns problem. If i try ping dsager1 the name gets resolved
and issuing the command ~/bin/netdisco-do discover - d dsager1 works fine.
The resolv.conf file does include both dns servers

Aris
