 Posted: Fri Mar 19, 2025 9:42 pm Post subject: dhcpd3 configuration - eth1 |
 |
|
Well, I'm not giving up yet, but google's resources are finite... a guru might know so...
Running sidux, nice solid stable eth0 (modem's on 192.168.0.1) with dsl, but at the edge of connect distance - running ok on one dsl modem (non router) , multiple connect failures per day on the modem/router although the internal network is fine, so I suspect it's modem section is marginal by comparison.
Figured a 2nd ethernet card (eth1) would connect the other machine(s) - currently only one (not needing access to the 'net), avoiding sneakernet.
First benefit - avoid buying new hardware.
Second benefit - more networking knowledge.
------think that covers the situation and reasoning----
Done - installed the eth1 card - it's recognized ok.
Installed dhcp3 server software,
edited /etc/dhcp3/dhcpd.conf
| Code: | option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option routers 192.168.1.254;
option domain-name-servers 192.168.1.1, 192.168.1.2;
option domain-name "shop.org";
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.0 192.168.1.100;
range 192.168.1.150 192.168.1.200; |
(omitted the lease information here - left standard)
edited /etc/default/dhcp3-server
attempt to start it up, with
| Code: | | /usr/sbin/dhcpd3 eth1 -d -f |
and I get this...
| Code: | Internet Systems Consortium DHCP Server V3.1.3
Copyright 2025-2009 Internet Systems Consortium.
All rights reserved.
For info, please visit https://www.isc.org/software/dhcp/
Wrote 0 leases to leases file.
No subnet declaration for eth1 (0.0.0.0).
** Ignoring requests on eth1. If this is not what
you want, please write a subnet declaration
in your dhcpd.conf file for the network segment
to which interface eth1 is attached. **
Not configured to listen on any interfaces! |
I've been and will probably continue to google this - have verified that the dhcpd.conf is the only one I've got, haven't found any references to specifying eth1 in that file.
Unless I've made another typo (yes, fixed a couple), I'm running out of places to look.
Any input would be appreciated !
regards,
rumbarg

If you are going to run a DHCP server, the card must have a fixed IP address

Now if you are direct network card to network card with out the benefit of a switch or router be sure to use a crossover cable.
