Comment 11 for bug 1225327

the sftp program in RHEL 6.1/6.2/6.3/6.4 has a bug in tty settings.

The 5.3p1 sftp program used in RHEL 6.1/6.2/6.3/6.4, and Ubuntu 12.04 LTS has tty attributes setting problem.

Steps to Reproduce:
1. stty -echo
2. sftp user@server
3. key in pass as prompted.
4. cd /tmp
5. ls
6. bye
7. stty -a

Actual results:
The entered sftp sub-commands in step 4 to step 6 are visible, and the OS command entered after sftp in step 7 is also visible.

Expected results:
Those inputs entered in step 4 to step 7 shouldn't be visible.
This is for security reason we want to hide the sftp subcommands when presented in the menu for user to get files.
