According to my manuals, the recvfrom call does not require the
socket to be connected.  However, I am getting an immediate
return with the error: Socket not connected.  Any ideas?

This is what the code fragment looks like:

#include <sys/types.h>
#include <sys/socket.h>

#define SOCKNAME "mysocket"

main()   /* server */
{
int s,ns; /* socket descriptors */
static struct sockaddr name = {AF_UNIX,SOCKNAME};
static struct sockaddr nname;
int nnamelen;
int imsg;

if ((s=socket(AF_UNIX,SOCK_STREAM,0)) < 0){
	perror("cant open socket");
	exit(-1);
	}

if(bind(s,&name,sizeof(name)) < 0){
	perror("cant bind to socket");
	exit(-2);
	}

nnamelen = sizeof(nname);
if(recvfrom(s,&imsg,sizeof(imsg),0,&nname,&nnamelen) < 0){
	perror("server recvfrom error");
	exit(-5);
	}

/* this is where it fails */
