Description Andrew Martynov 2004-09-22 12:35:51 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7)
Gecko/20040616

Description of problem:
Startup script /etc/rc.d/init.d/dhcpd does not check
availability of /var/lib/dhcp/dhcpd.leases file.

So if this file is removed DHCP server does not started.

Version-Release number of selected component (if applicable):
dhcp-3.0pl2-6.14

How reproducible:
Always

Steps to Reproduce:
1. install DHCP server
2. create simple config like attached
3. /sbin/service dhcpd start
4. /sbin/service dhcpd stop
5. rm /var/lib/dhcp/dhcpd.leases
6. /sbin/service dhcpd start
    

Actual Results:  Server stopped with error

Expected Results:  Server starts and working with clean leases database

Additional info:

It is good idea 
- to check /etc/dhcpd.conf for lease-file-name statement
- if no options included 
-- check if file /var/lib/dhcp/dhcpd.leases exists 
-- otherwise 'touch /var/lib/dhcp/dhcpd.leases'



Sample of /etc/dhcpd.conf
#----------------------------------
ddns-update-style none;
authoritative;

subnet 172.16.0.0 netmask 255.255.0.0 {
        ddns-updates off;
        max-lease-time 259200;
        default-lease-time 259200;
        option broadcast-address 172.16.255.255;
        option subnet-mask 255.255.0.0;
        option domain-name "mylan";
        option domain-name-servers 172.16.0.147, 172.16.0.10;
        pool {
                ddns-updates off;
                range 172.16.0.1 172.16.0.127;
                }

}

Comment 1 Jason Vas Dias 2004-09-22 14:36:08 UTC
This problem has been fixed for some time, in dhcp-3.0.1+ .
dhcp-3.0.1-8 will be in RHEL-3-U4 .
Meanwhile, you can get dhcp-3.0.1-7 compiled for RHEL-3 from:
