But as far as rkhunter itself goes, I do believe that the trouble was my not running the --propupd just as you mentioned. :oops: If you want to look at that thread, it's http://forums.linuxmint.com/viewtopic.p ... 2&t=207441 My last post there will have the log file you requested.

EDIT: Wait...what??? I was responding to a post by you that doesn't seem to be there. :? :lol:
I've been leered at over things like 'this'. Hey, I'm good, but I'm not that good.
Yes, some black stump stuff for sure.
I guess I edited a quoted reply incorrectly, or double-edited sounds about right.
No worries some folks say!!!

Here's the basic text:
You need to always run

Code: Select all

rkhunter --propupd
under any the following conditions
  1. apt-get upgrade
  2. apt-get dist-upgrade
  3. apt-get dist-upgrade
  4. any edit of /etc/rkhunter.conf
from the report, it appears you haven't run

Code: Select all

rkhunter --propupd
and things have greatly changed since it was installed and/or first run.
Would you agree with my estimate?

We can squash most false-positives on Ubuntu-flavored hosts with 2 commands and one insert.
And we can't blindly do that until you (well 'we/me' with you) examine closely what is
generating those Warning:(s)
and that is in /var/log/rkhunter.log

can you pastebin that file before you do anything else with rkhunter?

Code: Select all

cat /var/log/rkhunter.log | pastebin
and give back the short url?

Thank you.
All things will be more clear after the weekend and we are almost there...!!!

Stuff I have left to 'do' after the weekend:

rkhunter
  • Examine /var/log/rkhunter.log
  • Verify Warnings there.
  • Update /etc/rkhunter.conf
  • Update propupd after
  • Re-scan with rkhunter
  • Goal is "No warnings were found while checking the system."
  • Upgrade rkhunter to 1.4.3
  • Rinse.
  • Lather.
  • Repeat.
fix gufw for untrusted WiFi .
  • re-install with purge gufw
  • Pray it works.
Outa here.

Yeah, I might have said that once or twice myself. 'Course, it usually has a "mate" on the end. :lol:

Sounds good to me. I really appreciate your help. :D

  • Upgrade rkhunter to 1.4.3

Code: Select all

cd /usr/src/
wget "http://rkhunter.cvs.sourceforge.net/viewvc/rkhunter/rkhunter/?view=tar"
mv index.html\?view\=tar rkhunter.tar.gz
tar zxf rkhunter.tar.gz
mv rkhunter rkhunter-1-4-3
cd  rkhunter-1-4-3
./installer.sh --install
rkhunter --update
Stop here.
Have you recently posted the /var/log/rkhunter.log file?
I guess they have a shelf-life?
http://paste.linuxmint.com/view/kj2z says "bugger off" :)

Next step is
edit rkhunter.conf...

Apparently so. :( I used the "|pastebin" pipe (I have an account but I didn't want to go through the trouble of logging in when this was so much simpler.) Oops! I know better now.

While the current log file says that rkhunter is version 1,4,3 (after following your instructions), rkhunter --version reports 1,4,2. Should I have purged the old version first?

yeah, the | pastebin is a clever time-saver
You can still remove 1.4.2 AFTER >

Code: Select all

cat /var/log/rkhunter.log | pastebin
using the method you used to install 1.4.2.

Sorry--what do you need? The current rkhunter log only has the info of my setting it up. I do have one old log that I believe is the same as the one I pastebined--is that the one you want?

NO!
That tells rkhunter that everything on the system is "good".
When we are not sure that it is.

Right. Glad I asked. :lol:

You're probably not going to like this, but anyway

Code: Select all

aussie! fred # rkhunter --update && rkhunter -c -sk  -l /root/rkmanual.log && cat /root/rkmanual.log | pastebin
Unable to find configuration file: /usr/local/etc/rkhunter.conf
If I need to I can copy over a conf file from another machine (Arch) and use that--it's unedited, so it should be the same.
Thanks a lot, Habitual!

How about we look for one on your drive first? ;)

Code: Select all

sudo find / -name rkhunter.conf -type f
show me this result please.

Also

Code: Select all

grep ^PermitRootLogin /etc/ssh/sshd_config
does that say "no"?

Also is the arch version the same (1.4.3) and its rkhunter.conf in /etc?

Give me a moment to stop and feel stupid... Okay, done. :D

Code: Select all

fred@aussie! ~ $ sudo find / -name rkhunter.conf -type f
/usr/src/rkhunter-1-4-3/files/rkhunter.conf
fred@aussie! ~ $ grep ^PermitRootLogin /etc/ssh/sshd_config
grep: /etc/ssh/sshd_config: No such file or directory

Code: Select all

fred@aussie! ~ $ ls /etc/ssh
moduli  ssh_config
Rkhunter in Arch is 1,4,2.
The log for rkhunter indicates that there is a separate config file for version 1,4,3--I suppose since 1,4,2 was still installed at the time. It's under rkhunter.conf.datecode Do you think I should rename it to rkhunter.conf? (The old config file would have been removed when I used apt-get with the --purge flag to uninstall rkhunter 1,4,2. I'm telling you--today is not my best day!)

Code: Select all

rkhunter --checkconfig
if that doesn't barf, issue

Code: Select all

rkhunter --propupd
then

Code: Select all

rkhunter -c -sk

One or 2 little things and this will be done. Done. DONE!

Oh, Habitual. Did you really think it would be this easy? ;)

No worries, mate. I really appreciate your help, but please don't feel pressured! Take as much time as you need/want.

I'm going to follow your original instructions on my Arch build (removing the current rkhunter first) and see what happens.
