    Its under Status
    second item, Device list
    Every time someone trys to log into your network it logs the MAC address and it stays there even if they disconnect. If they dont know your security key then it does not give them a IP address. If your network is unsecured or they figure out the key then a IP is given to them. If you click on the MAC address you can add them to the MAC filter and block them.

    In the device list it reports weather they are connected by

    Eth1 = wireless plus signal strength
    Bro = wired or no connecting at this time
    Vlan1 = Wan port

    At least this is what I figured out

    It is a good way!. at least, we can monitor real time that who are connecting or trying to connect to our network. However, with WRT54 command line, what is the command to enable us to get that information? / in case it has, so we might write a shell script to records and block them automatically.

    Any help please.

    This topic was covered before - do a search for WALLWATCHER

    In the interest of proactively securing your network here are several easy things you could do:

    - Create a whitelist of allowed MAC addresses on your wireless network

    - Limit the amount of DHCP leases you give out (e.g. hand out only 8 leases between .100 - .107)

    - Use static DHCP leases

    - Use static IP's

    - Use a combination of everything mentioned

    The effectiveness of the last 3 suggestions are limited to NOT using typical class C addresses (e.g. 192.168 or 10.10. etc...)

    well just a note: all the measures mentioned by radikaled will only protect you against the casual wireless hacker, and is easily broken by slightly more persistent ones.

    for the security conscious, just use wpa2 encryption (=

    wpa or wpa2 should be suffient as long as you use a strong key. Both are susceptable to offline brute force attacks but if you use a really long key it would take far to long to break to be useful.

    Turning off the wireless when not in use is a good idea too. On only during certain times of day etc.
