Hi experts,
                  I am a gamer.A friend asked me to host his gaming server on VPS.I can not give access to whole directory to him.So i decided to create a separate user for him.I searched on google and found a method to add user restricted to a specific directory.I have executed all commands carefully and created a new user and group.Now whenever i login with my new account putty shows " remote side unexpectedly closed the connection ". 
Here is the method i used to create new user and group.

Please help me if there is any alternate method, or should i retry this more carefully once again.
My Current Operating System
Ubuntu 16

Sharing your VPS with CubeData are we?
Just to inform you, reminder on our TOS/AUP if he does anything against our TOS/AUP the responsibility for it, still falls on you. just keep this in mind please.

If you didn't already fix this...

Code: (Select All)

Match Group somegroup
 ForceCommand internal-sftp
 ChrootDirectory /somegroupdirectory/
 PermitTunnel no
 AllowAgentForwarding no
 AllowTcpForwarding no
 X11Forwarding no

The edit you made in /etc/ssh/sshd_config from above may have caused your SSH server to not accept connections. Try something like this and your SSH should then work again:

Code: (Select All)

sudo apt-get install --reinstall openssh-client

or

Code: (Select All)

sudo dpkg-reconfigure openssh-server

If you want to share game server the best way is to install a panel like ogp. Pufferpanel , pterodacttl , etc and create server from it . It automaticaly create sftp user and also it have its own file manager
