both support this, the problems seems to comes from host_timeout values ( 400ms )
see :
1°/ default printerdrake setting :
[EMAIL PROTECTED] admin]$ nmap -r -P0 --host_timeout 400 --initial_rtt_timeout 200
-p 9100
Starting nmap 3.30 ( http://www.insecure.org/nmap/ ) at 2003-10-30 15:50 UTC

I suspect it's because I run nmap several or someone print to this laser just
before ...

description:
I've got 2 network printers, a Konica 7830n ( 192.168.1.40 ) and a Lanier 5227
( 192.168.1.30 ) with static IP.
I noticed that when using autodetection, printerdrake is unable to detect them. I have
to specify the IP adress manually, the same applies also sometimes for diskdrake
concerning NFS server detection.
So I dig a little in /usr/lib/libDrakX/printer/detect.pm
Note : my broadcast is 192.168.1.255.
1°/ Is the detection routine ( getIPsInLocalNetworks() ) is very right ?
-> If I cut & paste it on shell, I have this :
[EMAIL PROTECTED] admin]# ping -w 1 -b -n 192.168.1.255 | cut -f 4 -d ' ' |
sed s/:// | egrep '^[0-9]+\\.[0-9]+\\.[0-9]+\\.[0-9]+' | uniq | sort
WARNING: pinging broadcast address
-> If I omit the \\ for \
[EMAIL PROTECTED] admin]# ping -w 1 -b -n 192.168.1.255 | cut -f 4 -d ' ' |
sed s/:// | egrep '^[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+' | uniq | sort
WARNING: pinging broadcast address

192.168.1.160
192.168.1.254
192.168.1.40
-> As the warning is annoying and should not appear :
[EMAIL PROTECTED] admin]# ping -w 1 -b -n 192.168.1.255 2>/dev/null | cut -f
4 -d ' ' | sed s/:// | egrep '^[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+' | uniq |

192.168.1.154
192.168.1.160
192.168.1.254
192.168.1.40
-> So this is fine. Now what's about the routine which scan the differents host
( whatNetPrinter ) ?
nmap -r -P0 --host_timeout 400 --initial_rtt_timeout 200 -p 9100
192.168.1.40
First time I test I had nothing and nmap failed with "skipping host
