Package: openssh-client
Version: 1:4.2p1-7
Severity: wishlist
Tags: patch
Hi,
please support the use of smart cards in the openssh-client package.
The attached file contains the necessary patches
- to build an additional package 'openssh-client-sc' that uses
opensc to support smart cards
The package 'openssh-client-sc' conflicts with 'openss-client' and
'ssh' as well as 'openssh-server' are adapted to depent on either of
the client packages.
- that allow asking for the smart card pin in case ssh-agent isn't used
(from opensc CVS; also in bug #608 in OpenSSH's bugzilla)
Thanks in advance
Peter

+Description: Secure shell client, an rlogin/rsh/rcp replacement with smartcard
support
+ This is the portable version of OpenSSH, a free implementation of
+ the Secure Shell protocol as specified by the IETF secsh working
+ group.
+ .
+ Ssh (Secure Shell) is a program for logging into a remote machine
+ and for executing commands on a remote machine.
+ It provides secure encrypted communications between two untrusted
+ hosts over an insecure network. X11 connections and arbitrary TCP/IP
+ ports can also be forwarded over the secure channel.
+ It is intended as a replacement for rlogin, rsh and rcp, and can be
+ used to provide applications with a secure communication channel.
+ .
+ This package provides the ssh, scp and sftp clients, the ssh-agent
+ and ssh-add programs to make public key authentication more convenient,
+ and the ssh-keygen, ssh-keyscan, ssh-copy-id and ssh-argv0 utilities.
+ .
