Offline OPKG

The following text is help how to install the OPKG package on an IPLOG unit that does not have Internet access. The installation will require a computer that has an Internet connection, on which the required packages will be downloaded, which will then be copied to the IPLOG unit via the SCP protocol or via a USB drive. Some packages depend on another package, so you must download all related packages and start installing from the last package that has no other dependencies.
The second option is to add to the OPKG configuration file the path to the local directory where the packages will be saved.
Current packages are available at address http://www.iplog.eu/opkg/base/
