Re: [BLUG] Meeting tonight?

Ana:

The presentation will go ahead regardless of whether there is a projector.

Without a projector, people just get to hear me lecture. Don't bother
taking notes, just sit back and know that all the good stuff will be
available online. (*)

Cheers,
Steven Black

(*) People should still try to make it to the meeting, if possible.

Re: [BLUG] Meeting tonight?

I'll be there tonight, just maybe a half hour late. I
have to play hooky a little bit between jobsites but
that's ok.

Is the projector situation under control? I'm not sure I'll make it tonight (although I plan to try!)

The meeting is at 7pm at the Monroe County Library in room 1B.

I will be giving a presentation on "Easy and Effective Theming".
Specifically covering theming from startup on.

Included will be:
    * GRUB background images
    * Usplash themes (*)
    * GDM themes
    * Screen savers
    * System icons

With the broad topic, I'll be covering a lot of ground. There will be a link
on the website < http://www.bloomingtonlinux.org/> for this meeting
<http://www.bloomingtonlinux.org/wiki/32nd_meeting > which will include a
link to a 5.3 page paper (plus references/links).

(*) Usplash was created for Ubuntu. I know it is a little distribution
specific, but it is a popular distribution (and I use it). Included in
the paper are comments about the differences of Usplash to alternatives
like Bootsplash and Gensplash, as well as links to information to
create themes for those.

[BLUG] Meeting tonight?

New subscriber to the list. Old goof that just got tired of Windows.
Linux geek wannabe. CLI phobic, but able to follow directions. Wanna
keep learning. Looking to add to my resources, currently mostly Usenet
and Web forums.

Not sure if I could make it anyway, but there's been no announcement
concerning the monthly meeting since I signed up a week or so ago. Is it
on? Any specific topic or theme?

What if everything in there is actually spoofed too, or for that matter
our whole human existence is just one giant spoof, man?

What if this email is a spoof and Mark Krenz wrote this? Or, what if
this Mark Krenz spoofed email is also a spoof and I really wrote it?

Have I blown anybody's mind yet?

Re: [BLUG] spoofed process names?

Cool... note that this modifies the command line string, not the actual program name.   Depending on the arguments you pass to ps you can still see the actual program name.  The "f" in "ps -ef" causes it to display the command line instead of the program name.

So "ps" looks like this:

25660 pts/1    00:00:00 perl

and "ps -ef" looks like this:

ajpoland 25660 25574  0 08:43 pts/1    00:00:00 hello there!

Nah, its "normal".  Consider this perl program:

#!/usr/bin/perl

$0="hello there!";

sleep 1000;

run it and then do a ps -ef:

bdwheele 31578 31505  0 08:31 pts/6    00:00:00 hello there!

From the perlvar manpage, there's a description of what's going on:

       $PROGRAM_NAME

       $0      Contains the name of the program being executed.

               On some (read: not all) operating systems assigning to $0 modi-

               fies the argument area that the "ps" program sees.  On some

               platforms you may have to use special "ps" options or a differ-

               ent "ps" to see the changes.  Modifying the $0 is more useful

               as a way of indicating the current program state than it is for

               hiding the program you're running.  (Mnemonic: same as sh and

               ksh.)

               Note that there are platform specific limitations on the maxi-

               mum length of $0.  In the most extreme case it may be limited

               to the space occupied by the original $0.

               In some platforms there may be arbitrary amount of padding, for

               example space characters, after the modified name as shown by

               "ps".  In some platforms this padding may extend all the way to

               the original length of the argument area, no matter what you do

               (this is the case for example with Linux 2.2).

               Note for BSD users: setting $0 does not completely remove

               "perl" from the ps(1) output.  For example, setting $0 to "foo-

               bar" may result in "perl: foobar (perl)" (whether both the

               "perl: " prefix and the " (perl)" suffix are shown depends on

               your exact BSD variant and version).  This is an operating sys-

               tem feature, Perl cannot help it.

               In multithreaded scripts Perl coordinates the threads so that

               any thread may modify its copy of the $0 and the change becomes

               visible to ps(1) (assuming the operating system plays along).

               Note that the view of $0 the other threads have will not change

               since they have their own copies of it.

Re: [BLUG] spoofed process names?

Wow, easier than I expected. Fortunately you can still find out what
the actual process is called by grepping out the Name: line in /proc/[pid]/status

Re: [BLUG] spoofed process names?

I know that the mysql client (in the 3.x series) used to have a way of
removing the password argument from showing up in the process list. I
always wondered how they do that. I think I tried it again recently and
it doesn't do that anymore. Maybe something has changed in Linux that
prevents it now (which I think is the right thing to do).

It could be that the system you logged into itself has some kind of
process table viewing protection. There are some patches for Linux that
make it so that you can't view other user's processes. But that's
different from what you are asking about.
