Hi, i need some help getting user.txt and a shell.

I’ve got everything up to the L** on Port 4**, can read the directories of all the major characters. But in the directory of b***** (german city), i get id_*** and id_., but it always says "Permisson denied"or that the path is not a directory (same with the user.txt). I assume that the id_*** is needed to log into s** to get user shell. Can anyone please give me a nudge.

Thx

edit: got user
