Maybe I'll try this next, then:
http://napp-it.com/manuals/web-gui/index.html, as the author wrote:
i have not the time to build base napp-it appliances for unix, mac or windows, but it should run if you have a webserver installed and cgi/perl enabled.
Edit: Well I tried it, but I didn't as far as with ZFSguru. It seems to be installed in the right (/var/web-gui/wwwroot/) location (according to the readme.txt), and Apache is configured accordingly. Added a napp-it user and added that to sodoers. Also checked that perl is working in webroot/.
But the main script gives an error and no web GUI:
(2)No such file or directory: exec of '/var/web-gui/wwwroot/cgi-bin/napp-it/admin.pl' failed
Premature end of script headers: admin.pl
Running it with a proper debugger like Komodo's to find out which files it cannot find should help, but I won't have time to set that up.
Now one reason could be, that it cannot find a file which the readme instructs to install: 'install mbuffer -> copy folder tools/mbuffer to /' Now mbuffer is not on my system and the included binary is a Solaris binary.
The author writes: 'Napp-it is a copy and run web application. Copy and run means, you just have to copy napp-it to your cgi-bin folder ... and set permissions of napp-it folder to 777 recursively...
...
1. napp-it core files in ..cgi-bin/napp-it/ admin.pl and admin-lib.pl
you will only need these two files to have napp-it running. napp-it will create all other needed folder on first login.'
This makes it sound quite easy, and somehow it should run. Any suggestions what else to try?
