Fedora system - Connection close after connection - not using chroot jail (solved)

[Fernando F. M M. <fr...@ce...>]

Q: In a Fedora system, when I connect to an account NOT configured to use a 
chroot jail, I just get a "Connection closed" message. Why? 
A: Fedora creates a group called rsshusers:
     rsshusers:x:488:
and install rssh as /usr/bin/rsshd with permission 0750 and owher 
root.rsshusers:
    -rwxr-x--- 1 root rsshusers 24128 Mai 18 18:12 /usr/bin/rssh
So, users should be included at group rsshusers to run rssh.

Command used to test the connection:
[frota@crux ~]$ sftp hel...@rs...domain.ex 
hel...@rs...domain.ex's password: 
Connection closed                                                             

[frota@crux ~]$ scp hel...@rs...domain.ex:ap7131/* .              
hel...@rs...domain.ex's password:                                  
/usr/bin/rssh: Permission denied                                              

[frota@crux ~]$ scp hel...@rs...domain.ex:ap7131/* .               
hel...@rs...domain.ex's password:                                  
scp: ap7131/*: No such file or directory
