I tried this option but it didn't seem to work correctly.
the dhcpd.conf now is (server IP 220.127.116.11):
subnet 18.104.22.168 netmask 255.255.255.224
subnet 172.18.140.0 netmask 255.255.255.0
option routers 172.18.140.1;
option subnet-mask 255.255.255.0;
option broadcast-address 172.18.140.255;
option root-path "22.214.171.124:/tftpboot";
option tftp-server-name "126.96.36.199";
option bootfile-name "/tftpboot/pppoe.tlv";
range 172.18.140.100 172.18.140.105;
On the other hand, I sniffed the traffic using ethereal and the DHCPOFFER
Your (client) IP address: 172.18.140.100 (172.18.140.100)
Next server IP address: 188.8.131.52 (184.108.40.206)
Relay agent IP address: 172.18.140.2 (172.18.140.2)
Client MAC address:Integrit_09:ee:3f (00:10:6d:09:ee:3f)
server host name: 220.127.116.11
Boot file name /tftpboot/pppoe.tlv
Magic cookie: (OK)
Option 53: DHCP Message Type = DHCP offer
Option 54: Server Identifier = 18.104.22.168
Option 51: IP Address Lease Time = 10 seconds
Option 1: Subnet Mask = 255.255.255.0
Option 28: Broadcast Address = 172.18.140.255
Option 3: Router = 172.18.140.1
To know exactly what the output should be I have run Solaris DHCP and it
works fine and the output was the same with these additional options:
Option 17: Root Path = "/tftpboot"
Option 67: Bootfile name = "pppoe.vlt"
Option 66: TFTP Server Name = "22.214.171.124"
Option 31: Perform Router Discover = Enabled
So how can I add these options in ISC DHCP. The previous dhcpd.conf didn't
work with me. In addition where can I know the option number if I know the
Morever I want to use failover server, will this work since in failover I
should add "deny dynamic bootp clients".
Thanks in advance.
