[stunnel-users] launch stunnel server daemon from php?

Tue May 6 00:01:31 CEST 2008

Thanks, Brian.

The following php script works fine to start up the polipo web proxy cache
program.  /etc/polipo/standard.conf contains some standard config file
settings.  The command line parameters proxyPort, socksParentProxy, pidFile,
and logFile are additional config settings passed to the polipo executable.
<?php
      //
      $exec_command = 'polipo -c /etc/polipo/standard.conf proxyPort=8123
socksParentProxy=localhost:9050 pidFile=/var/lib/polipo/9050.pid
logFile=/var/log/polipo/9050.log ';
      $exec_output = '';
      $exec_result_string = @exec($exec_command, $exec_output,
$exec_result_int);
      $exec_output_lines = count($exec_output);
      if (@openlog('', LOG_NDELAY | LOG_PID | LOG_PERROR, LOG_LOCAL0)) {
        $log_datetime = date('Y-m-d H:i:s');
        @syslog(LOG_INFO, "polipo started on port 8123 at " .
$log_datetime);
        @closelog();
      }
?>

 The following php script does not work.  It hangs and has to be
interrupted.  If I run the same command from the shell as root it works
fine.  I have tried changing the foreground = yes to foreground = no and
removing the & character at the end of the $exec_command but neither works.
<?php
      //
      $exec_command = '/usr/local/bin/stunnel /etc/stunnel/test.conf &';
      $exec_output = '';
      $exec_result_string = @exec($exec_command, $exec_output,
$exec_result_int);
      $exec_output_lines = count($exec_output);
      if (@openlog('', LOG_NDELAY | LOG_PID | LOG_PERROR, LOG_LOCAL0)) {
        $log_datetime = date('Y-m-d H:i:s');
        @syslog(LOG_INFO, "stunnel started at " . $log_datetime);
        @closelog();
      }
?>
/etc/stunnel/test.conf is as follows:
setuid = apache
setgid = apache
pid = /var/lib/stunnel/test.pid
output = /var/log/stunnel/test.log
foreground = yes
syslog = yes

[stunnelTest]
accept = 7199
connect = 8123
client = no
transparent = no
