Hi, bird needs something like this because in case it daemonizes it still keeps the fds open of the controlling tty which is bad in case you'd like to log out which then will hang. I already opened a Debian Bug - See: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=427772 Flo diff -Nur bird-1.0.11/sysdep/unix/main.c bird-1.0.11.flo/sysdep/unix/main.c --- bird-1.0.11/sysdep/unix/main.c 2007-06-20 09:13:21.000000000 +0200 +++ bird-1.0.11.flo/sysdep/unix/main.c 2007-06-20 09:21:00.000000000 +0200 @@ -434,7 +434,18 @@ die("fork: %m"); if (pid) return 0; + setsid(); + + /* Close all FDs and thus detach from controlling tty */ + for (i=getdtablesize();i>=0;--i) + close(i); + + /* create harmless stdin/out/err */ + i=open("/dev/null",O_RDWR); + dup(i); + dup(i); + } signal_init(); -- Florian Lohoff flo@rfc822.org +49-171-2280134 Those who would give up a little freedom to get a little security shall soon have neither - Benjamin Franklin
