btraceback(1) [debian man page]

BTRACEBACK(1)					     Network backup, recovery and verification					     BTRACEBACK(1)

NAME

	btraceback - wrapper script around gdb and bsmtp

SYNOPSIS

       btraceback /path/to/binary pid

DESCRIPTION

       btraceback is a wrapper shell script around the gdb debugger (or dbx on Solaris systems) and bsmtp, provided for debugging purposes.

USAGE

       btraceback  is called by the exception handlers of the Bacula daemons during a crash.  It can also be called interactively to view the cur-
       rent state of the threads belonging to a process, but this is not recommended unless you are trying to debug a problem (see below).

NOTES

       In order to work properly, debugging symbols must be available to the debugger on the system, and gdb, or dbx (on Solaris systems) must	be
       available in the $PATH.

       If  the	Director  or Storage daemon runs under a non-root uid, you will probably need to be modify the btraceback script to elevate privi-
       leges for the call to gdb/dbx, to ensure it has the proper permissions to debug when called by the daemon.

       Although Bacula's use of btraceback within its exception handlers is always safe, manual or interactive use of btraceback is subject to the
       same  risks  than  live debugging of any program, which means it could cause Bacula to crash under rare and abnormal circumstances.  Conse-
       quently we do not recommend manual use of btraceback in production environments unless it is required for debugging a problem.

ENVIRONMENT

       btracback relies on $PATH to find the debugger.

FILES

       /usr/lib/bacula/btraceback
	      The script itself.

       /usr/sbin/btraceback
	      symbolic link to /usr/lib/bacula/btraceback

       /etc/bacula/scripts/btraceback.gdb
	      the GDB command batch used to output a stack trace

NAME

       bacula-dir - Bacula Director

SYNOPSIS

       bacula-dir [options]

DESCRIPTION

       This manual page documents briefly the bacula-dir command.
       Bacula's  Director  Daemon  acts  as the controller of the network backup system: it is responsible for scheduling and coordinating backups
       across the network.

OPTIONS

       -c file
	      Specify the configuration file to use.

       -d nn  Set debug level to nn.

       -dt    Print timestamp in debug output.

       -f     Run in foreground (for debugging).

       -g group
	      Set the group/gid to run as.

       -m     Print kaboom output (for debugging)

       -r job Run <job>.

       -s     No signals (for debugging).

       -t     Test the configuration file and report errors.

       -u user
	      Set the username/uid to run as.

       -v     Set verbose mode.

       -?     Show version and usage of program.

TCP-WRAPPERS CONFIGURATION
       Tcpwrappers looks for the service name of the bacula daemons in hosts.allow , and the service names of these daemons is	configured  to	be
       different from the binary.  The service names are configured to be %hostname%-%component% rather than bacula-dir (As defined in the bacula-
       dir.conf.in file)

       So the hosts.allow entry has to match %hostname%-%component% (servername-dir for example) instead of bacula-%component%

       WARNING: This means that if the hosts.allow file has the entry:

       bacula-dir: ALL

       you will not be able to run bconsole to connect to the local director!

       The entry would have to read:

       server-dir: ALL

       and this will allow the console to connect to the director.  (The process running is bacula-dir.)
