This is actually considered a security feature. you would not want to compromised daemon to prompt you for a login/passwd. Most daemon that are coded correctly will shortly after startup, close the open file descriptors before going into daemon mode. So in this case, SELinux is a second line of defense. if you trust all your confined daemons, you can use following com to enable your daemon to talk to the tty: setsebool -P allow_daemons_use_tty=1 BTW, for http, there is specific boolean: httpd_tty_comm > > avc: denied { read, write } for comm="ntpd" dev=devpts egid=0 euid=0 exe="/usr/sbin/ntpd" exit=0 fsgid=0 fsuid=0 gid=0 items=0 name="0" pid=17348 scontext=user_u:system_r:ntpd_t:s0 sgid=0 subj=user_u:system_r:ntpd_t:s0 suid=0 tclass=chr_file tcontext=user_u:object_r:devpts_t:s0 tty=(none) uid=0 > > > SELinux is preventing /usr/sbin/cupsd (unlabeled_t) "create" to (unlabeled_t). > SELinux is preventing /usr/sbin/cupsd (unlabeled_t) "append" to /var/log/cups/error_log (cupsd_log_t). > SELinux prevented /sbin/rpc.statd from using the terminal /dev/pts/0. > ......, there are a bunch of them. sorry for not posting them. > > dmesg does not show any of these when running dmesg from the terminal. > see > http://www.geocities.com/olivares14031//20070821164505-dmesg.htm > for details.
