Dear Ladies and Gentlemen,

I am writing to say that I am not sure where this problem is located,
despite the program behaving differently on 3.4-RELEASE to 4.1-RELEASE.

A test program

#include <strings.h>
#include <stdio.h>
#include <sys/types.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <syslog.h>
#define FACILITY                LOG_USER        /* default */

int
main(int argc, char *argv[]) {

  struct sockaddr_in    addr ;
  struct in_addr        my_addr ;

  if ( argc != 2) {
    printf("Usage: %s dotted decimal IP address\n", argv[0]) ;
    return(1) ;
  }
  bzero(&addr, sizeof(addr)) ;
  if ( inet_aton(argv[1], &addr.sin_addr) == 0 ) {
    printf("%s: inet_aton failed\n", argv[0]) ;
    return(1) ;
  }
  openlog ("test_me", (LOG_CONS | LOG_PID), FACILITY);
  syslog ((FACILITY | LOG_NOTICE), "connect from [%s]", inet_ntoa
(addr.sin_addr));
  printf("address was %s\n", inet_ntoa(addr.sin_addr)) ;

  return(0) ;
}

on the problem system (4.1-R) works Ok so the problem is not obviously
a different syslog or inet_ntoa on 4.1-R.

The usage that causes the client address to be mangled is 

  while (TRUE) {
    /* wait for a client to connect */
    if ((csfd = accept (ssfd, (struct sockaddr *) &c_addr,
&c_addr_len)) == -1) {
.. yada yada ..
    syslog ((FACILITY | LOG_NOTICE), "connect from [%s]", inet_ntoa
(c_addr.sin_addr));
    
This seems quite reasonable to me. I would appreciate your comments.

Thank you,

Yours sincerely.
