Hello, When using the console (instead of xfree86's gui), today I started getting the following error to pop up every once in a while: Jan 10 18:20:41 tucson1 kernel: arplookup 24.1.240.41 failed: host is not on local network I have no idea what that ip address is and when I tried to to a "man arplookup" to read into the problem a little, I had zero luck. When looking on google, all I can come up with for common errors leading to this is that people have made a mistake in setting their netmask for their subnet. In my ipf.rules file (not ipfw), whenever I refer to my personal IP (which is static)...I have xxx.xxx.xxx/32. From my understanding, this should be correct. Also, I do not have a rule relating to this IP address. I am not sure what is going on. I have attached my ipf.rules file if you are interested, if you need anything else let me know. Has my setup been hacked or is this something else I have managed to screwed up? Any tips are appreciated.... TIA, Thomas Kersten p.s.-also...any tips on making my rules better for a web/ftp server are welcome also.....:) !!!!!!!! __________________________________________________ Do You Yahoo!?
