nmap script engine error

I'll work on getting a fixed package to Jaunty.

OK; here's the patch which should fix this problem, awaiting upload.

+usr/share/nmap/*
+usr/lib/nmap/*

Could we please try to not refactor the packaging until we have sorted out debian? e.g. here its that debian package explicitly lists all files; changing that to wildcard changes the spirit of package.

Also the indentation change of Build-Depends is a similar packaging refactoring that will eventual future merges unnecessary hard.

Adding Homepage: entry in ubuntu is similarly not the way to go until its sorted that debian will accept something like this.

Same for dropping maintainer scripts that do nothing.

In short: could you come up with a patch that fixes this bug in a minimal fashion?

Thanks!

lets try to get this fixed for alpha 4. milestoning, targetting.

Any update? Can we get a minimal fix now for alpha 4?

 - Alexander

Update: jonathen said he would prepare a minimal diff to fix this.

Minimal patch: include missing usr/share/nmap/scripts/UPnP-info.nse file.

uploaded. thanks!

This bug was fixed in the package nmap - 4.76-0ubuntu2

---------------
nmap (4.76-0ubuntu2) jaunty; urgency=low

  * debian/nmap.files: Included missing 'UPnP-info.nse' file needed to fix
    script scan (LP: #319656).

this bug (or a variant of it) is still present in nmap-4.76-0ubuntu4. See output below:

The rest of the scan finishes with success.
My machine was upgraded from 8.10 to 9.04, if this matter.

I can confirm that. I'm running nmap-4.76-0ubuntu4 as well and received the following output:

Will the case be re-opened then as I'm seeing that it's marked as "Fix released" up above. As a side note, I'm new to using launchpad so forgive me (and teach me) if I am misunderstanding the process here.

Here's a patch which I think should eliminate all the script engine errors...at least all the ones I saw. It seemed like there were a bunch of other files besides UPnP-info.nse which needed to be included, so I added them in the same way Jonathan's last patch did.

(P.S. - I'm very new to submitting patches so please let me know if there's something I didn't do right.)

I just figured out how to reopen this - hopefully it's an appropriate action since this is technically not completely resolved yet (though see my submission above).

Just tried Kevin changes (rebuilding nmap), and everything seens to work as expected.
Did a couple of scans and didn't find any problem.
One special way to test it might be: nmap -A --script=/usr/share/nmap/scripts <host>
Which will run all scripts installed.

The debdiff worked for me as well. Thanks so much for that! It's my first attempt at installing a patch. The Ubuntu Packaging guide wiki had the steps perfectly laid out for applying a debdiff and now my Zenmap works properly! So, will this patch work it's way into the update manager as an update to fix the bug now?

I rebuild nmap with this patch, but it didn't work.
The errors are still available.

I can confirm this bug in Karmic

I tried Kevin Chang pathes it's working but after I build the deb file I got this error after install

Setting up nmap (4.76-0ubuntu5) ...
dpkg (subprocess): unable to execute post-installation script: Exec format error
dpkg: error processing nmap (--configure):
 subprocess post-installation script returned error exit status 2

any ideas?

Kevin Chang's debdiff resolved all issues for me on 9.04 Jaunty - thank you for creating it.

Thanks Kevin Chang, your debdiff worked for me as well. Great work.

Kevin Chang's debdiff resolved all issues for me on 9.04 Jaunty. Remember that after applying .debdiff you must compile with:

./configure
sudo make
sudo make install

The package is still broken in Jaunty (ie: no update in -proposed), running nmap 4.76-0ubuntu4

Output after running all available scripts was:

hi asac, could you have a look to the debdiff there?

guys, can we really open _new_ bugs for variants not covered by a patch landed for a bug ;)... thanks! anyway, this is ok now and I will check this tomorrow.

Ack, that reminds me...I had found a few things I missed and made a new patch, but forgot to submit it. I only tested the first time around with -A, which does --script=default, but --script=all brings up a few more missing file errors. I threw those into nmap.files as well, and checked that it matches the actual full set of nse/lua files in the src, so it should be good now hopefully.

I don't know if the list in nmap.files was ordered in any particular way - it looked fairly random to me, so I took the liberty of sorting the nse and lua files in there...

Thanks Kevin, can you add introductions to reproduce the issues discovered after the initial upload to summary, so i can do some happy testing?

Also, could someone also forward this to debian? maybe even one of the first that had the wildcard install rather than listing all scripts individually. in any case, a debian bug would be good.

I'm assuming that by "the initial upload", you mean my first upload? In any case, to summarize -

nmap 4.76-0ubuntu4 (the newest version in the repo):
Running `nmap --script=default localhost` (or `nmap -A localhost`, which does the same level of script scanning) produces the following errors:

SCRIPT ENGINE: '/usr/share/nmap/scripts/dns-test-open-recursion.nse' threw a run time error and could not be loaded.
SCRIPT ENGINE: error while initializing script rules:
/usr/share/nmap/scripts/script.db:20: rpcinfo.nse is not a file!
stack traceback:
        [C]: in function 'Entry'
        /usr/share/nmap/scripts/script.db:20: in main chunk
        [C]: ?
        [C]: ?

SCRIPT ENGINE: Aborting script scan.

My first patch:
`nmap --script=default localhost` completes successfully.
`nmap --script=all localhost` produces the following error (which also happens with --script=all on 0ubuntu4):

SCRIPT ENGINE: error while initializing script rules:
/usr/share/nmap/scripts/script.db:6: dns-safe-recursion-port.nse is not a file!
stack traceback:
        [C]: in function 'Entry'
        /usr/share/nmap/scripts/script.db:6: in main chunk
        [C]: ?
        [C]: ?

My second patch resolves this as well.

Does this cover the info you need?

Is there anything else I can or should be doing to help this bug along? I don't know if it's still present in Karmic, but it would be nice to get it stamped out there if it is.

Karmic working.

Confirmed here too. Looks like it's all good now. Big thanks to those who worked on this and got it committed!

The latest 9.04 package 4.76-0ubuntu4 is still broken.

Can we get a backport? I'm not moving to 9.10 because of all the new bugs it introduced... (I can't use 8.04 LTS because I need some of the newer 9.04 packages.)

Hello I am new to Linux and nmap and I am getting the same bug as Whoop at the top of the page. I have read through the posts on this page and see the proposed patches but I am not sure how to apply the patches. They are in text format and I am not sure where to apply them. I am using Ubuntu client/desktop. I could use some instructions on how to apply the necessary patch as I need to learn how to use nmap.

A bit confused.

However, I am closing it because the bug has been fixed in the latest development version of Ubuntu - Lucid Lynx.
