Sorry if I am repeating someone else here, I came into this conversation late and missed most of it. Arpwatch will keep an eye on your LAN for changes to MAC addresses as well as IPs, and will email you a report to boot. So, if someone were to attach to your wLAN, you could find out about it this way, even if they attempt to use a previously used IP address to try to mask their login, because arpwatch will show changes in Ethernet card vendor too. Nmap will allow you to probe a system on your LAN or not to look for open ports and/or listening services. Etherape will give you a visual display of traffic on your LAN. It's not very useful for trapping events because a trail can disappear fast, but it can help you distinguish traffic visually. To actually monitor what is going on within a LAN: Ethereal is a nice X tool, but it is a resource hog and can intermittently lock up, especially if you let it run on and on, capturing and displaying packets. I prefer a good command-line tool instead, such as ngrep (network grep). This is a packet sniffer that will allow you to capture part or all of the traffic emanating from or going to a particular system, or your entire LAN. You can spool the packets to disk to be read later, or set up a shell script to occasionally email you a copy of the spool file and then empty it for more data. -- G-Books is sponsored by http://lowendmac.com/ and...

Re: Can I monitor my network?
Hello all; especially Steve and Bruce, Thanks for all the info. I'm really surprised something SIMPLE hasn't been created yet to monitor the PC/Mac traffic on a private wired/wireless network. When I mentioned MacStumbler, I was referring to how it detects networks. I'd like a program laid out the same way as MacStumbler. . . except instead of detecting networks, is detects other computers logged onto your network. This can be done by simply popping up a DNS address or port ID that the computer is currently using, then if it's someone you know, you should be able to re-name that ID to whatever he/she calls their computer on a network. For example, my Pismo is called, Zoltans-Computer on a network. Wouldn't that be a nice and simple app.? I'm not interested in WHAT they are doing on my network, I just want to know WHO is on my network and when. The programs Steve and Bruce mentioned are very powerful in their own right, but are not what I'm looking for. These programs made me think about my previous Amiga days. . .which I don't need to think about anymore; programming in Assembler back in the late 80's, early 90's was what I primarily did on my Amiga, creating games for the Atari Lynx. YIKES! It was a nightmare to say the least. Programming and hacking are the two things that caused my nervous breakdown several years ago. I simply don't have the patience anymore; which is why I switched to Mac back in 1991. I fell in love with the idea that the easier an OS is to use, the more powerful it is. I still have many programming friends from the day and they haven't had a brain fart like me, and they are pretty interested in my idea for this basic yet powerful little tool to be able to simply see who's on and when. Now, this is for Bruce. . .using the GO/NETWORK command in finder is useful, but it will only show who's online when they are using a Mac and have file sharing turned on. If file sharing is turned off, then nothing shows up at all. I've noticed that a friend of mine showed up the other week using a Dell laptop, but he had Windows XP's version of file sharing turned on. . .something like network sharing or to that effect. Not sure if that was even supposed to happen, but it did. For what it's worth, I thank all for responding to my thread. . .who knows, some day I may have my own little app. that will do this. Of course, it will be freeware! :) Zoltan THE BLUETOOTH (and WiFi) MASTER i.e., Master at set up, install, understanding interference and custom configs. . .but NOT hacking, programming. . .anymore. -- G-Books is sponsored by http://lowendmac.com/ and...

MacStumbler is a program for finding networks. Most people needing to find other computers on their network use the network browser, built into the OS, like the finder Go Network link, or the Network icon in a finder window. Um, you did look there, right? :-) However, what you're talking about is intrusion detection, which is another kettle of fish entirely. As it is NmapFE is pretty simple.

For a huge subject, you are so far the ONLY one to respond and yet with another question. I'm the kind of guy that believes what a person is actually doing online on my network is their business. . .what I want to see is simply the traffic levels; that is, to be able to look at this and determine that yes, there is another computer connected to my network. While my wireless network is ABS based and encrypted, I sometimes feel that there's a neighborhood kid out there kickin' back on his laptop snickerin' 'cause he figured out my password or hacked somehow into my network. If I am sure I'm the only one on it, then I can take further steps. With what I have now, the only indication that someone else is using the network is the activity lights on both my modem and my ABS. I need a program that can not only detect activity, but confirm that yes, the activity I'm seeing is in fact another computer on my network.

Re: Can I monitor my network?
what I want to see is simply the traffic levels; that is, to be able to look at this and determine that yes, there is another computer connected to my network. Does the ABS not tell you what devices are connected to it - I'm guessing here as I use a Netgear router - which does. Also can you restrict the network to certain MAC addresses, that and an unguessable WEP password makes you pretty tight IMHO. -- Best wishes Malcolm Cornelius - The Powerbook Fanatic http://www.pbfanatic.co.uk -- G-Books is sponsored by http://lowendmac.com/ and...
