ssh reveals password

[helgman]

Not sure if this is the right place but since I'm accessing a "server" and I see the problem as security-related I post it here.

I have a few systems (Ubuntu and Debian) that I only access via SSH. This is fine but sometimes you don't want to log in, get a shell and then type in your command, so you head for the ssh foo "ps -A" or whatever.

I recently noticed that if you run a command as above but with the sudo-command the sudo password is displayed in plain text like this:

$ ssh foo "sudo gnump3d-index"
user@foo's password:
[sudo] password for user:password-that-I-type

Is there anything I can do in my configuration or is this "how it works"?

Regards,
Helgman

Thats how it works.
I think since the release of 7.10

When you type your password nothing is displayed to screen.

It sounds like it was 'fixed' in sudo v1.6.9p6 (it's the same issue as runing sudo in the background) however I think this may mean your example won't work as you won't be prompted for a password (given you're not a connected terminal) hence the remote sudo will fail.
