 Priority:  normal                 |  Milestone:  Awaiting Review

-----------------------------------+-----------------------------------
 The current wordpress 3.4.1 wp-admin/includes/class-wp-filesystem-ssh2.php
 code will crash php or spin in an endless loop when someone supplies
 ssh/sftp credentials (username/password) to an (open)ssh server where
 users don't have a shell and are chrooted to their home directory e.g. by
 using openssh's sftp-internal server and ChrootDirectory functionality.
 There is no neat fix for the code in the WP_Filesystem_SSH2 class. I've
 implemented a new WP_Filesystem_SFTP class making use of the portable
 phpseclib library.

 At this moment it is necessary to change a line in wp-
 admin/includes/file.php to be able to use WP_Filesystem_SFTP.
 Attached is the code for this new class up for review or for anyone with
 the same problem.
