DHCP server using tiva

Take a look at this page. The PPT describes how to do a DHCP Server on the NDK. The DHCP slides are at the end of the PPT.

 Note: this page incorrectly said "DNS" instead of "DHCP". I corrected that this morning.

the tutorial is nice but actually i need to know, if i enabled the DHCP server feature, Am i able add a configuration somewhere to Assign specific MAC address to specific IP address?, so my board act like a real DHCP server

The DHCP Server in the NDK does not have that feature.

Todd

is there any plan regarding adding this feature any time?

Thank you Todd

Hello, Todd ! Recently, I also  have this  problem. I have downloaded and read the ppt.Maybe I don't understand the connection between .c and .cfg file. So I want to know whether I need configure in C source file  when I configure dhcp server in .cfg file. In addtions, I also have trouble when I configure DHCP Server as ppt says. The problem is as follows:

Why I can't set the server interface and address?

My C code is as follows:

CI_IPNET NA;
CI_ROUTE RT;
IPN IPTmp;

// Setup manual IP address
bzero( &NA, sizeof(NA) );
NA.IPAddr = inet_addr(LocalIPAddr);
NA.IPMask = inet_addr(LocalIPMask);
strcpy( NA.Domain, DomainName );
NA.NetType = 0;

// Add the address to interface 1
CfgAddEntry( hCfg, CFGTAG_IPNET, 1, 0,
sizeof(CI_IPNET), (UINT8 *)&NA, 0 );

// Add the default gateway. Since it is the default, the
// destination address and mask are both zero (we go ahead
// and show the assignment for clarity).
bzero( &RT, sizeof(RT) );
RT.IPDestAddr = 0;
RT.IPDestMask = 0;
RT.IPGateAddr = inet_addr(GatewayIP);//

// Add the route
CfgAddEntry( hCfg, CFGTAG_ROUTE, 0, 0,
sizeof(CI_ROUTE), (UINT8 *)&RT, 0 );

// Manually add the DNS server when specified
IPTmp = inet_addr(DNSServer);
if( IPTmp )
CfgAddEntry( hCfg, CFGTAG_SYSINFO, CFGITEM_DHCP_DOMAINNAMESERVER,
0, sizeof(IPTmp), (UINT8 *)&IPTmp, 0 );

CI_SERVICE_DHCPS dhcps;
// Specify DHCPS Service on IF-1
bzero( &dhcps, sizeof(dhcps) );
dhcps.cisargs.Mode = 0;
dhcps.cisargs.IfIdx = 1;
dhcps.cisargs.IPAddr =inet_addr("192.168.2.10");
dhcps.cisargs.pCbSrv = &ServiceReport;
dhcps.param.PoolBase =inet_addr("192.168.2.1");
dhcps.param.PoolCount=200;
dhcps.param.Flags =DHCPS_FLG_LOCALDNS;
CfgAddEntry( hCfg, CFGTAG_SERVICE, CFGITEM_SERVICE_DHCPSERVER, 0,
sizeof(CI_SERVICE_DHCPS), (UINT8 *)&dhcps, 0 );

It looks like you have a different question. Can you please open a new thread?

Todd

I don't how to open a new thread.But I think reason why I can't set in XDC Windows(NA) is that my dscp server failed in initializing. Where are errors in my codes ?
