I'm facing a weird problem while trying to setup Chroot SFTP on ubuntu server. SSH is getting crashed whenever I am trying to setup Chroot SFTP. Logs are not showing any error. The only error in logs was related to LOCALE environment and I had fixed now. This error does not seem to be related to chroot. In short I'm clueless. I had tried the following steps.
1. Created new user for SFTP
2. Commented the existing "Subsystem sftp" and added the following.
Subsystem sftp internal-sftp
3. Added the following lines for user.
Match User sftpuser
4, Set permissions for sftp directory to root.user
5. Restarted ssh and its down.
I had tried commenting the "UserPam" in ssh config as well. This is the same for ubuntu 11 and ubuntu 12. Can anyone share some ideas?
