Configuration problem whit DHCP3

[cayaman]

Hello everyone

I'm trying to setup a DHCP3 server whitout succes

1- I have configured dhcpd.conf whit these parameters:


option domain-name-servers 10.0.0.1;

default-lease-time 60;
max-lease-time 72;

ddns-update-style none;

authoritative;

log-facility local7;

subnet 10.0.0.0 netmask 255.255.255.0 {
range 10.0.0.100 10.0.0.254;
option routers 10.0.0.1;
option domain-name-servers 10.0.0.1;
}


2- I want to launch dhcp3 on mon0 interface, so here is my command line:

ifconfig mon0 up 10.0.0.1 netmask 255.255.255.0



3- JSo I fire up DHCP3:

dhcpd3 -cf /etc/dhcp3/dhcpd.conf mon0


4- Then I received the following results:


cayaman@cayaman-laptop:~$ sudo dhcpd3 -cf /etc/dhcp3/dhcpd.conf mon0

Does anyone know how to fix this error?

I have read that
restorecon -v /var/run /var/run/dhcpd.pid
might fix it but I dont know what the above does and i need to install policycoreutils

will the above command fix this error and is it the correct thing to do?

I'm having the exact (and I mean exact since I'm looking at the Karma documentation too problem with Ubuntu 9. I noticed there are some bug reports about this but I've not read any solutions.

Also the solution you found by googling does not fix the issue. For some reason it cannot create this PID file. Any suggestions would be very appreciated.

Try starting dhcpd3 with this script.

/etc/init.d/dhcp3-server start


Its pid will be at /var/run/dhcp3-server/dhcpd.pid

Solved for me
ln -s /var/run/dhcp3-server/dhcpd.pid /var/run/dhcpd.pid
dhcpd3 -cf /etc/dhcp3/dhcpd.conf at0

I did something like this:
downlaoded dhcp server source files from: https://www.isc.org/software/dhcp/

than unpuck it, and in main directory:

$ cd server
$ make clean all

executable file show up: dhcpd

$ sudo ./dhcpd -cf $PWD/dhcpd.conf -lf $PWD/dhcpd.leases.5 -pf $PWD/killme.pid eth1
or
$ sudo ./dhcpd -cf /etc/dhcp/dhcpd.conf eth1 -pf killme.pid -lf dhcpd.leases.5

And I got this:

davinci@postry-System-Product-Name:~/Downloads/dhcp-4.2.1-P1/server$

It looks like it is working, I also got IP on this interface.

There are two ubuntu packages of dhcpd -- dhcp3-server and isc-dhcp-server. The former package is an obsolete version, you should be installing the latter package.
When I realized this I uninstalled both packages (and it seems I had managed to have them both installed). Then I installed isc-dhcp-server. The command: 'service isc-dhcp-server' can start and stop the service, and it is servicing clients.

Solved for me
ln -s /var/run/dhcp3-server/dhcpd.pid /var/run/dhcpd.pid
dhcpd3 -cf /etc/dhcp3/dhcpd.conf at0

Solved for me too.
Thanks!
