------- Additional Comments From [EMAIL PROTECTED] 2003-10-30 15:55 ------- 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 WARNING: No targets were specified, so 0 hosts scanned.

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 192.168.1.10 192.168.1.101 192.168.1.102 192.168.1.103 192.168.1.104 192.168.1.105 192.168.1.151 192.168.1.152 192.168.1.153 192.168.1.154 192.168.1.160 192.168.1.254 192.168.1.40 -> 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 | sort 192.168.1.10 192.168.1.101 192.168.1.102 192.168.1.103 192.168.1.104 192.168.1.105 192.168.1.151 192.168.1.152 192.168.1.153 192.168.1.154 192.168.1.160 192.168.1.254 192.168.1.40 -> 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 192.168.1.40 due to host timeout" . When I removed --host_timeout 400, or If I do it a second time it works. So maybe host_timeout value should be increase ... Don't forget it's milliseconds ! But even by increasing these value, printerdrake still don't give me the list of network printer printers in my LAN. So what's wrong ? There's must be something wrong after ... I expect that printerdrake could give me the list of network printers in my LAN if I check autodetect printers and select TCP/IP/Socket printers ... And from this list I choose a printer and then configure it ... AM
