     Yeah, definitely a root-kit with filenames like "input.history" and
"catalog.events".  chattr didn't work.  I think most of the commands
have been compromised.  The little bastage didn't re-write the ls
command very well, though.  The files appear if you do an 'ls -a .*' to
display just the dot-files.  Then a few dot and non-dot-files
appear...to normal and root users.  It's a pretty neat hackk.  I really
only had sendmail and fetchmail semi-configured, and a bunch of
symlinks to docs and HOWTO's.  Oh, and commenting out half of
rc.profile. <grins>  I'm not losing very much.

     Had all that, except for the deterants.  The firewall's closed, and
I'm only running sendmail.  I have other services installed but
disabled, as they're not even configured yet.  I was planning on
activating the whole shebang with a runlevel change.  It's barely above
runlevel 1 at present.  It's really no big deal.  Helps me learn the
system.
     I was wondering though.  Do you know if it's possible to require
that both the executable and indestructible bits be set so a program
can run?  I was thinking of password protecting the chattr command, or
re-writing it so that it could only be executed from localhost, and
locking everything down.  You'd have a catch-22 scenario, if you
removed one of the bits from chattr, though.  You couldn't change any
binaries or libraries remotely without access to chattr, nor upload
anything that can be made executable without chattr. <grins>  I guess
admins who need full remote access won't like it, though.  Nor would
anyone using a package manager, or needing to do any programming.  I
guess there would have to be some kind of security toggle that only a
working chattr could disable.
     Myself, I'd prefer laughing my hairy butt off at some jerk trying
to upload a virus or root-kit that he can't even run.

 > Another lingering use for the Windows machine

     <laughs>  At least the [CENSORED] thing helped me get Linux

running.  That, and help from folks here and the cvale LUG.

Unfortunately, it seems I've already been hacked.  Looks like I'll have

to do a full, scratch Slackware reinstall.  Found some hidden files in

my home directory that aren't even root accessible.  At least I can

expect Windows to be hacked, so don't care what really happens  to that

particular OS.  It's made to be reinstalled from scratch anyway.

     Yeah, I'm thinking that the OCR algorythms would need to include
font recognition and size, and location information in the scanned
image.  Font size and location data should already be variables within
the OCR code, and possibly even font type.  I think the hard part would
be in deciding whether to make the program a stand-alone project, or to
modify the current OCR routines to communicate more info to stdout.
Maybe in HTML format, so you could use a browser to fill in the
blanks.  That, or maybe postscript, as long as it's not proprietary,
like Adobe's PDF scheme.  Oh well.  Something to while away the hours
in the future, I guess.

Michael,

Try 
chattr -i 
on those files inaccessible by root.

It should not be possible for files to be inaccessible by root.
It is possible that you now have a rootkit installed.
A hacker might for example replace your ls command
and your chmod command, or any other basic utilities
to make things appear as they are not.

Don't leave ports open!
Don't run services that you don't need.
Create some detterents so they go somewhere else instead.

Looks more like inexperience than a crack to me.

To put it differently, I don't see the evidence.

     <laughs>  Yep.  You're absolutely right.  I was typing 'ls -a' 
rather than ls -ad' and was seeing the contents of subdirectories.  In 
my own defense, I didn't hear the colon.  Live and learn, I guess, as I 
discovered my mistake yesterday when I was backing up files.  I had been 
rereading the screen by lines instead of by words.  Those 4 and 6 keys 
on SpeakUp's keypad made all the difference.  I'm still wondering how 
the .xine directory  got there, though.  I started X11 once to see if it 
spoke, and then another time to see if Orca was installed and ready to 
go, and then gave it the Ctrl+Alt+Backspace when nothing happened.  Last 
time I played with Xine was on my old Debian system.
     Well, I'm off to see if the less command can display 300 lines of 
text per screen.  Every time I try to   "play" something from the Honor 
Harrington series of novels, my synth crashes.  I guess the PC can't 
take all the excitement of David Weber's naval engagements, or it's 
female and prefers Nora Roberts' romance novels. <grins>  Okay, so I'm 
in love with Martha Harmon-Pardee's voice.  Sue me. <grins>  The "Eve 
Dallas"Sci-Fi series suckered me in, and now I'm interested in Peabody. 
  She's scrappy.
