Top Forums UNIX for Beginners Questions & Answers Changes in dhcpd.conf do not make a difference in DHCP service behaviour Post 303031954 by ekorgur on Friday 8th of March 2019 05:42:42 AM

I couldnt get the OS version yet. DHCP server is administrated by somebody else. I will update it soon.
DHCP Server 4.1.1-P1

I mentioned before that I was going to copy the /etc/dhcpd.conf to /etc/dhcp/dhcpd.conf
I did that and restarted the service.
Now I started to receive a new kind of error and the service doesnt start. How it was working before with /etc/dhcpd.conf is still something I have no idea.

Code:

Subnet declaration was defined as below.

Code:
ddns-update-style none;

subnet 172.17.126.192 netmask 255.255.255.224 {
   option broadcast-address 172.17.126.223;
   next-server 172.17.126.195;
   option routers 172.17.126.195;

   host fsb1 {
      option host-name "fsb1";
      option root-path "/gsn/nodes/fsb1";
      hardware ethernet XX:XX:XX:XX:45:06;
      fixed-address 172.17.126.200;
      filename "/BootFiles/fsb_gep3/linux/kernel/pxelinux.0";
   }

Because of the error seen in messages logs, or something else, the dhcpd service doesnt work anymore.

Text::DHCPLeases(3pm)					User Contributed Perl Documentation				     Text::DHCPLeases(3pm)

NAME
Text::DHCPLeases - Parse DHCP leases file from ISC dhcpd. SYNOPSIS
use Text::DHCPLeases; my $leases = Text::DHCPLeases->new("/etc/dhcpd.leases"); foreach my $obj ( $leases->get_objects ){ print $obj->name; if ( $obj->binding_state eq 'active' ){ ... } ... DESCRIPTION
This module provides an object-oriented interface to ISC DHCPD leases files. The goal is to objectify all declarations, as defined by the ISC dhcpd package man pages. This interface is useful for analyzing, reporting, converting lease files, or as a tool for other applications that need to import dhcpd lease data structures. CLASS METHODS
new - Class Constructor Arguments: Hash with the following keys: file - Leases file path Returns: Text::DHCPLeases object Examples: Text::DHCPLeases->new(file=>"/etc/dhcpd.leases"); INSTANCE METHODS
get_objects - Get objects from leases file Arguments: Object attributes to match (optional) Returns: Array of Text::DHCPLeases::Lease objects, or iterator depending on context. Examples: my $it = $leases->get_objects(ip_address=>'192.168.0.1'); while ( my $obj = $it->next ) ... print - Print all lease objects contents as a formatted string Arguments: None Returns: Formatted String Examples: print $leases->print; BUGS AND LIMITATIONS
Correct parsing of leases files depends on changes made to the format of said files by the authors of the ISC DHCPD package. This module was tested against leases files generated by ISC DHCPD version 3.1.0. In addition, I do not have access to leases file with all possible declarations and statements, so parsing could be broken in some circumstances. Patches are welcome. No bugs have been reported.
