In order to establish a secure connection between a server e.g. to use as a file repository and your machine, a typical secure protocol is SSH. In order to use SSH/SSH2, the standard tool is PUTTY. Putty establishes a secure SSH/SSH2 connection between the file server and your machine via terminal. Correct installation of Putty in order to establish connections, requires some technical expertise. Useful instructions can be found at:
Once the user logins to the server via a putty terminal, a GUI software can improve usability, such as Winscp or filezilla. Winscp allows insertion of PuTTy sessions even for a novice user. Both the novice and the experienced and the user can fine practical instructions in the truly useful site of WinScp.
Overall a great experience with putty and Winscp. Thanx Dr. G.D.
