problem with updateplugins.pl (inprotect Inst-Man step 12)

[Simon Meggle]

Hello,
i have installed inprotect on a red hat 9 machine with the following
packets:
PHP 4.3.9
Apache 2
Perl 5.8.0
nessus 2.2
inprotect 0.20

I followed the installation manual of inprotect, but on step 12 (running
updateplugins.pl) i have big problems. After exectuting updateplugins.pl i
can see in the logfile:
---- cut ----
Tue Nov 30 16:31:24 2004 updateplugins: No new plugins installed at
updateplugins.pl line 106.
---- cut ----



Line 106 in updateplugins.pl is:
---- cut ----
        #execute nessus-update-plugins
        #system ("nessus-update-plugins") == 0 or print localtime(time)."
updateplugins: No new plugins installed";
        #If used patch for nessus-update-plugins, we may pass parameter on
the command line.
 106==>  system ("nessus-update-plugins.141 -u $inprotect_url/nessus") == 0
or die localtime(time)." updateplugins: No new plugins installed";

        #Sleep 30 sec, allow nessusd to restart
        sleep 30;
---- cut ----22
