Description Konstantin 2009-11-23 02:17:28 UTC 
Description of problem:
Backslashes in banner file are doubled when displayed by SSHD.

Version-Release number of selected component (if applicable):
openssh-server-5.2p1-31.fc12.i686

How reproducible:
Create banner file containing this text: "/ / \ \".
Configure SSHD to use prepared banner.

Steps to Reproduce:
1. Start SSHD.
2. Connect to the server.
3. Enter user name. Check the banner.
  
Actual results:
Backslashed are doubled:
"/ / \\ \\"

Expected results:
Single backslashes:
"/ / \ \"
Comment 1 Tomas Mraz 2009-11-23 07:39:27 UTC 
The banner messages are escaped not by SSHD but by the ssh client so a rogue server can not send terminal escapes to the client's terminal.
