connect() hangs for me, with 1.3.70, 1.3.73 and 1.3.74. It is fine
under 1.3.63. This has something to do with my current configuration,
but I'm not sure how to best take this further. [I was running
1.3.70, and 1.3.73 without problem several days ago.]
If you need more detail, just tell me what you want me to examine.
#include <string.h>
#include <sys/types.h>
#include <sys/socket.h>
int fd;
struct sockaddr a;
#define d a.sa_data
main(){
fd=socket(AF_UNIX, SOCK_STREAM, 0);
if (-1==fd) exit(1);
a.sa_family= AF_UNIX;
strcpy(d, "/dev/log");
connect(fd, &a, sizeof a - sizeof d + strlen(d));
}
FYI, here's /proc/net/unix:
