Package: hddtemp Version: 0.3-beta13-9 Severity: normal When I start hddtemp over an ssh connection, the connection does not end by the logout. It's stuck. Logging in again over a different session and killing hddtemp solved the issue (as well as closing the terminal window).
The problem is because hddtemp does not properly daemonize itself as described in the UNIX Programming FAQ, 1.7: http://www.faqs.org/faqs/unix-faq/programmer/faq/ An patch which fixes the problem is attached, note however that it's incomplete because the FAQ says you should establish new open descriptors for stdin, stdout, sterr. Also, my three close statements are probably redundant. At least one is necessary however. And moving the daemon_open_sockets,openlog block is, I guess, also unnecessary. --- hddtemp-0.3-beta13.orig/src/daemon.c +++ hddtemp-0.3-beta13/src/daemon.c @@ -268,11 +268,17 @@ fd_set deffds; time_t next_time; - if (tcp_daemon) - daemon_open_sockets(); - - if (syslog_interval > 0) - openlog("hddtemp", LOG_PID, LOG_DAEMON); + switch(fork()) { + case -1: + perror("fork"); + exit(2); + break; + case 0: + setsid(); + break; + default: + exit(0); + } switch(fork()) { case -1: @@ -285,6 +291,18 @@ exit(0); } + close(0); + close(1); + close(2); + + if (tcp_daemon) + daemon_open_sockets(); + + if (syslog_interval > 0) + openlog("hddtemp", LOG_PID, LOG_DAEMON); + + + /* close standard input and output */ for(i = 0; i < 3; i++) { for (j = 0 ; j < sks_serv_num ; j++) -- System Information: Debian Release: 3.1 APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (1, 'experimental') Architecture: i386 (i686) Kernel: Linux 2.6.10-1-686 Locale: [EMAIL PROTECTED], [EMAIL PROTECTED] (charmap=ISO-8859-15) Versions of packages hddtemp depends on: ii debconf [debconf-2.0] 1.4.30.13 Debian configuration management sy ii grep 2.5.1.ds1-4 GNU grep, egrep and fgrep ii libc6 2.3.2.ds1-21 GNU C Library: Shared libraries an ii sed 4.1.2-8 The GNU sed stream editor -- debconf information excluded -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
