Basically that is a CGI script which runs locally on the NAS, and disguises itself as a http package repository. Using the web_prefix file the firmware package manager is pointed to it. The script downloads the ZYPKG_INFO.tgz or ZYPKGS file from several repositories, and combines that to a single file, on base of (alphabetically) sorting the packages. Further it keeps a database of origin of all those packages, and when requested it downloads and offers them.
How to install
Step 1
Download the file web_prefix, and put it in the directory \\<NAS>\admin\zy-pkgs\ on the NAS. Make sure your browser doesn't add any extensions to the file. The filename is web_prefix, without extension, all lowercase characters.
NAS5xx, NAS326
(Firmware 5.10+ only) On this NAS there is no subdirectory zy-pkgs in \\<NAS>\admin\. Just add it.
NSA-212 (Medion)
For the NSA212, there is no support for the web_prefix file, so the procedure is a bit different. Enable the Telnet Backdoor (see below), login over telnet (as root), and execute
Code: Select all
echo http://metarepo.tk/Users/Mijzelf/zypkg-repo/Medion >/etc/package_src_url
NSA series
In the packages menu in the webinterface execute 'Retreive list from Internet'. Install MetaRepository. Execute 'Retreive list from Internet' again.
NAS series
On the webinterface desktop, open the 'App Centre'. Goto 'Browse->All Apps'. Now there is a cycle icon on the page. Push it. install MetaRepository. Push the cycle icon again.
Medion
In the package menu in the webinterface execute 'Retreive list from Internet'. Do not try to install anything else than MetaRepository. When MetaRepsitory is installed, goto the MetaRepository page, and change 'ftp://ftp2.zyxel.com/+' in 'ftp://ftp2.zyxel.com/NSA310/4.40/zypkg/' (without the quotes), and if you also want the Medion repository add a line 'ftp://nas-download:sEhtalr@download.medion.de/package/'. Now hit apply, and re-retreive the package list. Warning: not all ZyXEL packages run on a Medion. Make sure you first install dropbear, and test it, to have an entrance if the webinterface fails.
How to configure
NSA series, Medion
In the package menu you can open the configuration page of MetaRepository.
NAS series
On the desktop you'll find a MetaRepository icon to open the configuration page.
Here you can enter the source repositories. When a package with the same name and version can be found in several repositories, the repository highest in this list is used. Further you can blacklist packages.
How to create your own (local) repository
Just put the package(s) in a share, in combination with a describing ZYPKGS file (case sensitive). Add the full path to the 'Repositories' list. Done. You can also supply a ZYPKG_INFO.tgz if you like. The script first tries to download/copy the ZYPKG_INFO.tgz file, and if that fails it tries ZYPKGS.
Telnet backdoor
On Medion boxes it is possible to start a telnet daemon on the NAS, by requesting a webpage:
Firmware 1.00:[/code]
http://<ip-of-nas>/r32694,/adv,/cgi-bin/remote_help-cgi?type=backdoor
Firmware 1.01(UZD.0):[/code]
http://<ip-of-nas>/r34814,/adv,/cgi-bin/remote_help-cgi?type=backdoor
Firmware 1.01(UZD.2):[/code]
http://<ip-of-nas>/r36258,/adv,/cgi-bin/remote_help-cgi?type=backdoor
You can login as admin, or as root, using the admin web password.
If your firmware version is not listed here, login on the webinterface of your nas, and have a look at the url to find out the 'r value' of your firmware version. Some browsers won't show this, in that case copy the url and paste it in notepad, or something like that.
(On most NSA boxes this telnet backdoor also works. Just find the 'r value' of your firmware. For other options read this.)
