tripwire while updating the policy settings: Error: Policy Update Changed Object.

As I was trying to remove some annoying entries in my Tripwire policy, I started getting errors. The first time I did not pay close attention, but the next day the policy had not changed! So I looked at it closer and noticed that if a file changed since the last update, then tripwire refuses to update the policy. That is, if the secure mode is set to high.

So to update my tripwire policy I was running:

sudo tripwire -m p -p /etc/tripwire/tw.pol --secure-mode low /etc/tripwire/twpol.txt

which now (at least since 13.04, maybe in 12.10?) means the secure mode is left alone and is marked as ...

"Your server runs WebDAV!" But how do you know?

Just got told that one of my servers was running WebDAV. I used that before so I thought it was turned on. Checking at the server, I could not find anything about DAV that was turned on in my server...

So, how could they detect WebDAV and not me??

The fact is that by default Drupal doesn't check the HTTP query method. It should! In fact, Drupal happily answers all methods with an HTML page. So I did not have WebDAV, just a flaky CMS.

How can you test methods that your server supports?

Knowing your IP address and port, use telnet like this:

telnet IP port (i.e. telnet 1.2.3.4 80)

Windows 2000 SP4, new logon policy forced to Roaming by default.

Not too long ago, I accepted the update from Microsoft to go to MS-Windows 2000 SP4. Neat. Except that when I rebooted (I think the 2nd time, but not totally sure, my wife used the computer in between, it seems...) it could not load my profile anymore.

Tripwire and updates

A week or so ago we updated our Ubuntu server to Intrepid and ran in a problem with tripwire that showed up like this:

    tripwire -m u -r <report-file>
    ### Error: Keyfile Read/Write error.
    ### /etc/tripwire/site.key
    ### Exiting...

We tried to renew the key file with the following:

    twadmin -m G -S /etc/tripwire/site.key

and it did not make any difference (other than the key file had a new date).

The permissions looked right too (root, u+rw only).
