Help for basic dhcpd.conf file !!!

Hi.

I work in a company from Brazil that makes maintenance in cable modens.
Here I have one DHCP and TFTP server in running on Windows. I use the "Network Registrar 5.5.13" software and one CMTS 1000 Arris.
The utilization here is only for maintenance of cable modem.
I will like of change the DHCP and TFTP server to Linux.
I set the dhcpd.conf file but the the cable modem don't receive IP.
I don't have very experience in Linux.
If someone can help me I will be very grateful.
Below my system configurations.

My server have only one network board with the IP 192.168.0.1.
My CMTS have the IP 192.168.0.26
My config of dhcpd.conf file

# dhcpd.conf
# Configuration file for ISC dhcpd (see 'man dhcpd.conf')
authoritative;
server-identifier cmts-asv;
default-lease-time 600;
max-lease-time 7200;
ddns-update-style none;
option domain-name "asv";
option domain-name-servers 192.168.0.1;
option routers 192.168.0.26;
option subnet-mask 255.255.255.0;

subnet 192.168.0.0 netmask 255.255.255.0 {}

subnet 192.168.0.0 netmask 255.255.255.0{
range 192.168.0.35 192.168.0.79;
option time-servers 192.168.0.1;
next-server 192.168.0.1;
option routers 192.168.0.26;
option time-offset -18000;
option tftp-server-name "192.168.0.1";
option time-servers 192.168.0.1;
option log-servers 192.168.0.1;
filename "ConfigFile.cm";
}

Thanks for help me and sorry for my "google english"

Any luck yet?

Hi!

This is probably an old post, but unless you have managed to make it work, you can perhaps make use of a few tips:

Check to see if the requests come to the DHCP server in the first place: tail -100f /var/log/messages | grep dhcp
This shows you the last 100 lines of the log file and grep shows lins containing "dhcp".

If your log files is /var/log/syslog, you use the following:

tail -100f /var/log/messages | grep dhcp

Example:
Jan 12 22:45:27 DHCPB dhcpd: DHCPDISCOVER from 00:23:ed:13:fe:28 via 79.24.235.1

Now the DHCP server should offer an IP address:

Jan 12 22:46:57 DHCPB dhcpd: DHCPOFFER on 79.24.235.145 to 5c:35:3b:15:3e:cd via 79.24.235.1

If you still need assistance, post a reply and I'll see what I can do.
