I know absolutely nothing about Linux. I am coming into a new position where someone else set up DHCP on Linux, but I need to be able to match an IP address with a computer name. Is there a way for me to get this information in a GUI format? If not in a GUI format, how can I access this info without a lot of fuss?

Thanks for you help.

Danilda,

Your DHCP server configuration information should be in /etc/dhcpd.conf.

If you want to assign a specific address to a specific-named machine, you can add a section similar to the following (changing the IP address, MAC address, and hostname to suit your setup):

host gannon {
hardware ethernet 00:60:09:C5:9C:DB;
fixed-address 192.168.3.14;
}

In this specific example, gannon is the machine name, 00:60:09:C5:9C:DB is the MAC address, and 192.168.3.14 is the IP address you want to assign. This is often referred to as 'reserved addressing'.

Sorry if I couldn't tell you an easier way to do it!

look at the /var/lib/dhcp/dhcpd.leases file,

It will contain the info for all machines that have been connected and given leases like this


lease 11.0.0.2 {
starts 4 2001/12/06 02:21:40;
ends 4 2001/12/06 11:21:40;
hardware ethernet 00:20:78:10:dd:5b;
uid 0g:00:38:34:57:00:3r;
client-hostname "WIN98";
}

lease 10.0.0.2 {
starts 4 2001/12/06 02:25:52;
ends 4 2001/12/06 11:25:52;
hardware ethernet 00:0t:6d:b5:39:ge;
uid 01:00:03:6d:13:39:11;
client-hostname "WINME";
}

use this to configure /etc/dhcpd.conf


The systems with the fixed address assigned in dhcpd.conf will not show up in the leases file.


You can open these files in your favorite gui editor. kate or gedit will work fine.


try this

gedit /var/lib/dhcp/dhcpd.leases


for the less fuss stuff select the line above with the left mouse button and center button click in a terminal or console
