Hi Everyone I have a quick question. Apparently someone has fired up a wireless device near one of my APs that is trying to request an ip from my dhcp server. Each hour my logfiles are filled with this:
Sep 27 18:01:18 logan2 dhcpd: DHCPDISCOVER from 00:0a:e9:00:b9:ca via 204.96.181.131: unknown client Sep 27 18:02:21 logan2 dhcpd: DHCPDISCOVER from 00:0a:e9:00:b9:ca via 204.96.181.131: unknown client Sep 27 18:03:25 logan2 dhcpd: DHCPDISCOVER from 00:0a:e9:00:b9:ca via 204.96.181.131: unknown client (204.96.181.131 is a Cisco 3550 switch at the hop before the traffic comes into the 3550 at my NOC) over and over and over. The dhcp server is acting exactly like it is supposed to and not allowing him an ip. However, two questions come to mind: 1) Is this hurting anything? The utilization on my box is minimal. I don't know a lot about how DHCP works. and had I known more in the beginning, would not be using it. Now thoughi t would be difficult to retrofit back to all static, though I may still do that at some point. 2) Is there any way of knowing where this is coming from? I doubt there is, but if I knew even which AP it was coming through that might be helpful. I don't have any sniffer capability, at least not right now. I have heard of this ethereal product, but haven't look at it and don't know if it will do what I want. I use Network General Sniffers at my other job (Union Pacific Railroad) and am fluent with them but don't have one here nor can I afford one. :( Thanks Sam ----------ANNOUNCEMENT---------- Don't forget to register for WISPCON IV http://www.wispcon.info/us/wispcon-iv/wispcon-iv.htm The PART-15.ORG smartBridges Discussion List To Join: mailto:[EMAIL PROTECTED] (in the body type subscribe smartBridges <yournickname> To Remove: mailto:[EMAIL PROTECTED] (in the body type unsubscribe smartBridges) Archives: http://archives.part-15.org
