nmap scans ports on a target machine and is a network exploration tool....
If you want to know who is connected to your AP
there should be a page in the AP-management where
you can see the connected hosts..... |

there is no such page (wrt54GS)
and the problem is also that i don't allow wifi acess to my configuration web-page for security reasons
by the way i found how to do with nmap but it is too slow because it scans ports
i realy need an ip scanner

it can't find 192.168.1.112 why?
| Code: | the 105 is my laptop running gentoo
# nmap -sP 192.168.1.112
Starting Nmap 4.01 ( http://www.insecure.org/nmap/ ) at 2006-11-02 18:16 CET
Note: Host seems down. If it is really up, but blocking our ping probes, try -P0Nmap finished: 1 IP address (0 hosts up) scanned in 0.456 seconds

either a bug in nmap (i use 4.11 instead of your 4.01) and/or a firewall active on .112 which doesn't answer on ping maybe.

i updated the coreutils but nothing changed
i also can't start the nfsd daemon and samba startup is very slow
but i have samba and nfs in the kernel:
# cat /proc/filesystems | grep nfs
nodev nfs
nodev nfs4
nodev nfsd
# cat /proc/filesystems | grep smb
nodev smbfs |
