IP problem
hi,
I intend to get a clarification on the DHCP working under Solaris8. Since i configured my Host with DHCP start, the dhcp client in my host queries and receives the IP and a valid Lease period from the DHCP Server running in the same LAN. This happens when the Host ip is 0.0.0.0 and netmask is ff000000 shown by ifconfig
With the same condition ( IP 0.0.0.0 and Netmask ff000000 ) i run a Server Application (Java) which creates a Datagram socket and waits at the port(1500 in my case). I also run a Client Application (Java) in another host having a valid IP which sends the packet to BROADCAST address (255.255.255.255) and port 1500.
My Server application cannot receive any packet. Even if the Client Application sends to my subnet directed broadcast address (192.168.3.255) it cannot . When the above condition is tried with Red Hat Linux 8.0 (kernel version 2.4.18-14) the server application receives the packet addressed to 255.255.255.255 and not the 192.168.3.255 ip address.
When the Host at 0.0.0.0 ip and Netmask ff000000 able to receive the DHCP reply , why it cannot receive the packet sent to it with the same procedure. Is the treatment differs for Kernel Level process and User Level applications ?.
Awaiting your valuable response which will be helpful for my Development.
thanks for ur reply in advance
sathish.
