Looking at the source of Proc::Deamon, it actually binds STDIN STDOUT and STDERR to /dev/null, so none of them will be bound to your terminal. It also uses fork() and POSIX::setsid() which should ensure that the process is completely disconnected from the terminal in all other ways. (update: note that this is more or less exactly what a daemon IS. if you don't want this behaviour, you probably don't want to run your code as a daemon at all)

Daemons usually don't read anything from STDIN anyway (since they're supposed to be run completely in the background). Is there a reason you want to use STDIN to read from a socket instead of opening the socket in the daemon process?

It may make sense to put the "main code" in a separate module (see perlmod) for two reasons: one, so you can logically separate the daemon setup code from the processing code (i.e. just to make it easy to find the code you want and ignore the code you're not currently interested in); and two, if you put the processing code in a module you can use that same processing code in a program that doesn't act as a daemon (for instance, when testing the processing code, you can call it from a simple test script that gives output to STDOUT).
