>Description:
Hi,
I am facing a problem while using UDP on FreeBSD Operating System. I am
using a test program to test a SNMP Agent. The test program and agent both
run on the same box. The test program uses local port 2000. The SNMP Agent
program listens on port 3000. (I will change these port numbers later as
per SNMP standard).
When the test program tries to send data to SNMP Server using sendto command
("127.0.0.1" , port 3000), it receives the error "Can't assign requested
address"
The same two programs work when run on an HP machine.
The code used by test program as below:
===============================================
if( (sk = socket(AF_INET, SOCK_DGRAM, 0)) == -1)
{
perror("Error in socket");
exit (errno);
}
/* bind a local port Number */
cln_addr.sin_family = AF_INET;
cln_addr.sin_addr.s_addr = inet_addr(INADDR_ANY);
cln_addr.sin_port = htonl(2000);
if ( bind(sk, &cln_addr, sizeof(struct sockaddr_in)) == -1)
{
perror("Local Bind error:");
exit (-1);
}
srvsnd_addr.sin_family = AF_INET;
srvsnd_addr.sin_addr.s_addr = inet_addr("127.0.0.1");
srvsnd_addr.sin_port = htonl(3000);
fromlen = sizeof(struct sockaddr_in);
.... code to prepare the Network Management request
/* send request to agent */
sndsts = sendto(sk, reqbuf , reqSize , 0,
&srvsnd_addr, sizeof(struct sockaddr_in));
if (sndsts == -1)
{
perror("Send Error");
exit (-1);
}
===================================================
The error is flagged from sendto call. I am using FreeBSD V3
>How-To-Repeat:
It is persistant behaviour.
