I feel for you. This is horrible IP software.
Using gdb, a live syscall facility (strace/ktrace),and objdump it's about a weeks worth or work to make this code useful to the oss world.
Otherwise it's crappily packaged, badly designed program limiters without a single compliant systems constraint.
Worked with flexlm packaged stuff for 3 years and that was enough.

Hello,
does anyone have a script that can check the contents of the /tmp directory and for example e-mail the directory content if anything other than session files are present?
Maybe there are better ways to monitor suspicous /tmp and /var/tmp activity, if so I'm listening :) (1 Reply)

trace
KTRACE(1) BSD General Commands Manual KTRACE(1)
NAME
ktrace -- enable kernel process tracing
SYNOPSIS
ktrace [-aCcdi] [-f trfile] [-g pgrp | -p pid] [-t trstr]
ktrace [-adi] [-f trfile] [-t trstr] command
DESCRIPTION
The ktrace utility enables kernel trace logging for the specified processes. Kernel trace data is logged to the file ktrace.out. The kernel
operations that are traced include system calls, namei translations, signal processing, and I/O.
Once tracing is enabled on a process, trace data will be logged until either the process exits or the trace point is cleared. A traced
process can generate enormous amounts of log data quickly; It is strongly suggested that users memorize how to disable tracing before
attempting to trace a process. The following command is sufficient to disable tracing on all user-owned processes, and, if executed by root,
all processes:
$ ktrace -C
The trace file is not human readable; use kdump(1) to decode it.
The utility may be used only with a kernel that has been built with the ``KTRACE'' option in the kernel configuration file.
The options are:
-a Append to the trace file instead of recreating it.
-C Disable tracing on all user-owned processes, and, if executed by root, all processes in the system.
-c Clear the specified trace points associated with the given file or processes.
-d Descendants; perform the operation for all current children of the designated processes.
-f trfile
Log trace records to trfile instead of ktrace.out.
-g pgid
Enable (disable) tracing on all processes in the process group (only one -g flag is permitted).
-i Inherit; pass the trace flags to all future children of the designated processes.
-p pid Enable (disable) tracing on the indicated process id (only one -p flag is permitted).
-t trstr
Specify the list of trace points to enable or disable, one per letter. If an explicit list is not specified, the default set of
trace points is used.
The following trace points are supported:
c trace system calls
f trace page faults
i trace I/O
n trace namei translations
p trace capability check failures
s trace signal processing
t trace various structures
u userland traces
w context switches
y trace sysctl(3) requests
+ trace the default set of trace points - c, i, n, p, s, t, u, y
command
Execute command with the specified trace flags.
The -p, -g, and command options are mutually exclusive.
EXAMPLES
# trace all kernel operations of process id 34
$ ktrace -p 34
# trace all kernel operations of processes in process group 15 and # pass the trace flags to all current and future children
$ ktrace -idg 15
# disable all tracing of process 65
$ ktrace -cp 65
# disable tracing signals on process 70 and all current children
$ ktrace -t s -cdp 70
# enable tracing of I/O on process 67
$ ktrace -ti -p 67
# run the command "w", tracing only system calls
$ ktrace -tc w
# disable all tracing to the file "tracedata"
$ ktrace -c -f tracedata
# disable tracing of all user-owned processes
$ ktrace -C
SEE ALSO
kdump(1)
HISTORY
The ktrace command appeared in 4.4BSD.
BUGS
Only works if trfile is a regular file.
