Hi all,

Just having one or two problems writing  a little network daemon:

1. Most programs in the inetutils distribution seem to lose their
controlling terminals as follows:

    int    tty = open( "/dev/tty", O_RDWR );
    ioctl( tty, TIOCNOTTY );
    close( tty );

All of the function calls proceed successfully, but the program stays in
the foreground. The alternative of fork()ing seems kinda like cheating.
Any ideas?

2. I want the program to listen on a given port on all network
interfaces. Programs running under inetd do this, but my program is
standalone.
Other standalone daemons seem to do this. Obviously when one binds to a
local address, it only listens on the interface to which that address
belongs, eg if i bind with the address 127.0.0.1, then my program won't
listen on my ethernet card's address.

Thanks in advance,
William Murphy
