Extra computers on my Network page

[trynreadme]

I set my amahi server to be the DHCP server and for some reason it's showing what looks like 2 extra computers, how do I disconnect them?

Are you sure they are not your computers?

From what I have seen, the IP addresses granted as a result of DHCP seem to stay around for a very long time.
So if you plugged in a laptop (for example) into your network 4 weeks ago, its address and hostname will likely still be listed in the hda networking dhcp screen, even though the computer is no longer there.

There might be other reasons why one of your computers might show up multiple time in that list. Perhaps you changed its hostname, or installed a new operating system?

Its a little tedious, but the way to investigate this is to use the following command:

Code: Select all

grep DHCPACK /var/log/messages

and look closely at its output. What you really want to look at is the MAC addresses and hostnames in the list.

Find the two computers in that list that are suspicious to you and then compare the MAC addresses of those to other computers on your network. Do they have the same MAC addresses as a 'good' computer on your network?

If you are interested, I wrote a Python script that parses the logfiles and extracts MAC and hostname info.
I posted it a while back. I'll try and find it again and add a link to it.
