hi!

i need ssh users and sftp users on my server. they don't mix so sftp users have a /bin/false
as their shell.

however when i try a ssh connect to such a user. he does not get disconnected but hangs forever.

can it be that sshd searches foer /bin/false in the chroot environment?

but i tried to place it there including ldd requirements. no success.

i just want sftp users to get no shell and also no hanging connections... sftp works right now.

thanks!

example user:

test:x:1012:1009::/home/test:/bin/false

maybe a new option: DisconnectOnShell yes
would help.
