Thread: Problems with sockets under linux

I've been screwing around with Sockets programming for a little while - just to see what it's like.

Code:

#include "../unp.h"
#include <time.h>

int main(int argc, char **argv)
{
        int     listenfd, connfd;
        struct sockaddr_in servaddr;
        char    buff[MAXLINE];
        time_t  ticks;

        listenfd = Socket(AF_INET, SOCK_STREAM, 0);

        bzero(&servaddr, sizeof(servaddr));
        servaddr.sin_family = AF_INET; bzero(&servaddr, sizeof(servaddr));
        servaddr.sin_family = AF_INET;
        servaddr.sin_addr.s_addr = hton1(INADDR_ANY);
        servaddr.sin_port = htons(13);

        Bind(listenfd, (SA *) &servaddr, sizeof(servaddr));

        Listen(listenfd, LISTENQ);

        for (;;)
        {
                connfd = Accept (listenfd, (SA *) NULL, NULL);

                ticks = time(NULL);
                snprintf(buff, sizeof(buff), "%.24s\r\n", ctime(&ticks));
                Write(connfd, buff, strlen(buff));

                Close(connfd);
        }
}

That's the code i'm using for a simple daytime server. Here are the errors that I'm getting:
