openssh unix dev - Jan 2013 - SSH from within OpenSSH

This is a request for a How-To

I need to SSH from my Windows 7 laptop to several Linux machines that are
inside a secondary VPN.

To explain: I have a network (Call it LAN A), containing a few Windows 2K
servers, that is protected by a VPN. That network connects to another one
(call it LAN B), that has a few Linux server, over a separate site-to-site
VPN.
>From outside (here) I have no access to LAN B as it only allows connections
from selected servers of LAN A.

I normally initiate a VPN session to LAN A, use Remote Desktop to open a
session on one of the W2K machines on LAN A, then use PuTTY to connect to
the desired Linux server.

Today, I tried OpenSSH. I installed it on the W2K server in LAN A.

Then I used PuTTY from my Laptop to W2K. Got the DOS prompt. One thing I
notice is that if I press any cursor key, W2K takes that to be a control
character. i.e. Pressing cursor and hitting enter gives and error: *'
command not found*. Yes, there is a single quote at the start.

Next, I used plink to connect to a Linux server on LAN B.

Issues:
At signin, the last character seems to get missed. So if I type "root"
as
userid I get prompted for the password for "roo", so I typed
"rootA". Same
thing with the password, so I had to type and extra character after it to
sign in.

The cursor key still doesn't work, or works intermittently. e.g. in VIM I
have to press one cursor key and then hit the space bar, etc.

There appears to be some ANSI conversion going on and on the Linux command
line I get messages such as &0a not found. Sometimes it gets stuck in a
loop printing such messages by the hundred.

Help?

You installed the OpenSSH ssh *server* ? Where did you get it from?

Yes, something seems to be wrong. Have you played with the different
options on PuTTY config? You don't have W2000 in an odd locale, do you?

Does it happen if you directly run plink from the remote desktop?
That would isolate it to the running of commands on W2K.

As a workaround, you could make a ssh tunnel (SSH/Tunnels). That way the
W2000 machine won't be processing your commands in any way (actually,
it could even have a keylogger installed, and it won't matter at all).

Still, it would be nice that it worked (even though Windows 2000 is well
beyond its End Of Life...).
