Portable OpenSSH is a Unix/Linux port of OpenBSD's excellent OpenSSH, a full implementation of the SSH1 and SSH2 protocols. It includes sftp client and server support. License: BSD License (original)Changes:
Execution of ~/.ssh/rc was disabled for sessionswhere a command has been forced by the sshd_configForceCommand directive (unsafe default behavior).Chroot support for sshd was added. Internalsftp-server support was added to sshd, to allowchroot operation without support files. A"no-user-rc" option was added to~/.ssh/authorized_keys to disable execution of~/.ssh/rc in public key authentication. An sftpprotocol extension, "posix-rename@openssh.com",was added to provide a rename operation with POSIXsemantics.
