Renaud, Nicolas,

 

Never mind, I figured it out.

 

You guys released a bunch of new Fedora Core 6 plugins over the past
week.  Those plugins call rpm_check (in rpm.inc) with the parameter
'release: FC6'.  Unfortunately, you forgot to test for 'release == FC6'
in rpm.inc.  I added that line, stopped nessusd, rebuilt
plugins-code.db, started nessusd, and re-ran the scan.  Problem solved. 

 

I trust you'll fix rpm.inc soon.  Those new fedora plugins were released
on Jan 17, which means they hit the registered feed on the 24th (Wed),
right?

Renaud, Nicolas,

 

The problem persists. Below is a series of tests I performed along with
the results.  (All tests conducted with Nessus 3.0.5 for ES4.  The
problem also occurred under Nessus 3.0.4, prior to upgrading).

 

Note the additional (possibly related) problem that plugin 19506 does
not report correct plugin information after running
nessus-update-plugins unless the .db files are deleted from
/opt/nessus/var/nessus.

 

I'm willing to send you more sensitive information and files off-list on
your request.

 

========================================

 

TEST 1:

 

- Stopped nessusd

- Uninstalled Nessus

- Saved /opt/nessus/etc/nessus/nessus-fetch.rc

- Deleted the /opt/nessus and ~/.nessus directories

- Re-installed Nessus (Nessus-3.0.5-es4.i386.rpm)

- Restored /opt/nessus/etc/nessus/nessus-fetch.rc

- Re-created Nessus users

- Ran /opt/nessus/sbin/nessus-update-plugins (no errors)

- Started nessusd (no errors)

- Performed the scan (same NessusClient, target, configuration)

 

RESULTS 1:

 

- The 'find_service.nes ... could not be found' messages are gone

 

- Target host, a fully-patched RHEL4 system, still shows 12 missing
Fedora patches (plugins 24049, 24051, 24052, 24054, 24067, 24077, 24078,
24188, 24189, 24196, 24229, and 24231)

 

- Plugin 19506 ERRONEOUSLY reports 'Plugin feed version : 200701050232'
and 'Type of plugin feed : Release', even though plugin_feed_info.inc
shows 'PLUGIN_SET = 200701200615' and 'PLUGIN_FEED = Direct'

 

========================================

 

TEST 2:

 

- Stopped nessusd

- Removed .db files from /opt/nessus/var/nessus

- Started nessusd

- Performed the scan (same NessusClient, target, configuration)

 

RESULTS 2:

 

- Target host still shows the same 12 missing Fedora patches

 

- Plugin 19506 now CORRECTLY reports 'Plugin feed version :
200701200615' and 'Type of plugin feed : Direct'

 

========================================

 

TEST 3:

 

- Installed Nessus on a 'clean' server

- Did not register or run nessus-update-plugins

- Created nessus users

- Started nessusd

- Performed the scan (same NessusClient, target, configuration)

 

RESULTS 3:

 

- No errors. Target host shows no missing patches

 

- Plugin 19506 CORRECTLY reports 'Plugin feed version : 200701050232'
and 'Type of plugin feed : Release'

 

========================================

 

TEST 4:

 

- Stopped nessusd on 'clean' server

- Registered Nessus (CE9D-50F1-F4F3-9862-1868)

- Running 'nessus-fetch --register' retrieved newest plugin set

- Started nessusd

- Performed the scan (same NessusClient, target, configuration)

 

RESULTS 4:

 

- No errors. Target host shows no missing patches

 

- Plugin 19506 ERRONEOUSLY still reports 'Plugin feed version :
200701050232' and 'Type of plugin feed : Release', even though
plugin_feed_info.inc shows 'PLUGIN_SET = 200701200615' and 'PLUGIN_FEED
= Registered (7 days delay)'

 

========================================

 

TEST 5:

 

- Stopped nessusd on 'clean' server

- Removed .db files from /opt/nessus/var/nessus

- Started nessusd

- Performed the scan (same NessusClient, target, configuration)

 

RESULTS 5:

 

- No errors. Target host shows no missing patches

 

- Plugin 19506 now CORRECTLY reports 'Plugin feed version :
200701200615' and 'Type of plugin feed : Registered (7 days delay)'

 

========================================

Follow-up (see below): I see a large number of "<service> depends

scanning from a freshly-installed server.  I see it only on the  

'direct-feed' server.

 

It seems like you've done a "rm /opt/nessus/lib/nessus/plugins/*"  

which you really, really don't want to do.

 

Re-install Nessus to fix this.
