hello,
i tried to install the ppp pakage required for pptp server. The installation
procedure says that we have to ftp the *.npk pakage to the server in binary mode and than issue a command /system reboot and pakage will get installed
I tried doing all this inspite of this the pakage cannot be seen when i issue a command /system pakage print
Can anyone help me out 
Did you use the same ppp-package version as your installed RouterOS?
Does a “/file print” still show the .npk file? If yes, it has not been installed (the .npk files get deleted after successful installation).
What does the system log say (something like “installation of xyz succeeded/failed”)?
thanks for the help i was using the wrong version pakage.
Rgds
