| DNS address? |
 Posted: Fri May 08, 2009 3:50 pm |

In the CCS TCP/IP stack, how can I manually assign the DNS server address? It seems to allways be dynamic..
I would like to point it to my router directly, for ex 192.168.1.1
I havent find where it could be done, unlike the unit IP-address, subnet mask and gateway.
It mostly seems to work allright anyway, but just to be sure..
anyone figured it out?
Thanks/tagge |

Hi, thanks, but there is no function, at least, as
"Set AppConfig.PrimaryDNSServer"
I assume I just cant write in the ip address in the struct.. SMTPServerAddr, or? how should it look like in that case?
What should I then disable to avoid the DNS functions to owerwrite it?
| Code: |
typedef struct _APP_CONFIG
{
IP_ADDR MyIPAddr;
MAC_ADDR MyMACAddr;
IP_ADDR MyMask;
IP_ADDR MyGateway;
IP_ADDR PrimaryDNSServer;
struct
{
unsigned char bIsDHCPEnabled : 1;
unsigned char bInConfigMode : 1;
} Flags;
WORD_VAL SerialNumber;
IP_ADDR SMTPServerAddr; // Not used. In CCS ???
IP_ADDR TFTPServerAddr; // Not used.
BYTE NetBIOSName[16];
} APP_CONFIG;
|
But most confusing is that the DNS address changes, and often to a not working one.. But only when reprogramming, not by reset 
Then it usually uses the last obtained, even if its not up to date..
But if I turn on the DHCP function, it get the right DNS.
Its all about resolving the IP to the SMTP server, thats needed.
but I would like to write the DNS address in manually, and wouldnt have to use the DHCP function. |

You should have also seen: | Code: | typedef int32 DWORD;
typedef union _IP_ADDR
{
BYTE v[4];
DWORD Val;
} IP_ADDR; |
That means you can write: | Code: | | AppConfig.PrimaryDNSServer.Val = make32(192,168,1,1); |
or maybe it should be: | Code: | | AppConfig.PrimaryDNSServer.Val = make32(1,1,168,192); |
? See which one works.
Just set the value at startup.

Works just fine! 
thanks
