Users of LAN-accounts have two possibilities. Both guaranty a protected use of all recourses which had been assigned to such an account via the Internet:

1. A Web-interface like Firefox can be used. This is for example favourable to read scripts, to navigate through the file system, to down- and upload single files, or if it is currently not possible to use a sFTP-client.
   (Firefox should be preferred, but all other common browser should operate too. Unfortunately, Internet Explorer has currently some updates which make difficulties not allowing scrolling!).
   
   
2. Access via sFTP with a suitable client like for example  WinSCP

Detailed explanations how to use these tools will be given by this  link.
