If you are in kernel space and want to find out the above info, you can use either of
the following, depending on where you are putting your code:
1. start from init_task and reach the task you want by comparing pids
2. Start from 'current' and do the same as above
3. Use the kernel routine 'find_task_by_pid()' to reach the task structure of the pid
you want to see.
In case you are in user space, you could use the method specified in one of the
earlier posts for the same question:
1. Read the 'stat' file of the /proc filesystem. The element kstkeip in it will give
it to you. Do a 'man proc' for details.

Look in the /usr/X11R6/lib/X11/xkb directory. It took me some time to find
this directory. I needed it because I am using a Silicon Graphics Keyboard on
my PC, and the standard keymap was not correct.

Dear Harold,

There is no such thing like a kernel debugger. You can remote debug
the kernel with gdb, which is very complicated, and I never managed to
do so.
So people normally use printk() and the proc-filesystem to follow
the flow of their modules/drivers.

I have found it now, but it is alpha software. So maybe not the right

Is dead a long time, since about 1996.
Since the fs-stuff in the kernel (especially VFS) seems to change a
lot, old code doesn't seem to be an option ;-( Otherwise ovlfs would
be brilliant.
Thanks everyone for the hints!

I don't think this is widely known but RedHat 6.2 flavored kernel also
includes the LFS patches and sufficiently new glibc. I haven't tried but
there should be no obstacles in producing files over 2GB on it.

These errors say that, in order to install this package, first you have
to install the packages it depends on... this is recursive, i.e. while
installing one of these package you may have to install other package as
well...

There was no backdoor. Illegal DLL? Later, only after the WSJ printed the FUD,
was there a minor buffer overrun found. However, the "!seineew era..." string
was not a password, and NO ONE has yet successfully used it as a password to
obtain anything from a server with FP98 extensions.

I do deny that it said "NETSCAPEENGINEERSAREWEENIES" because it actually said
"!seineew era sreenigne epacsteN", and it still isn't a password or anything
of the sort, no matter how much you try to rationalize it to your ignorant

Sorry, I don't know how to explain this. I don't have access to AIX or Solaris.
And I don't know much about the details of AIX and Solaris.
How did you 'put the message on console'? Is it something like 'printf( "...")'?
In Linux, you may try to press 'alt-1', 'alt-2', 'alt-3', and so, to switch
between virtual console. In case you don't aware of this feature, try it. If you
are in X window mode, try 'ctrl-alt-1' to switch to virtual console, and press
'ctrl-alt-7' to switch back to X window.

You need to decide on what to debug. If it is the kernel, kdb from the sgi
site is good (see James' post). If it is code in the user segment (app. code
