First of all I added

    (setq tramp-verbose 6)

to the ~/.emacs

Then M-x eshell, and then

    cd /ssh:username@hostname:/some/existing/dir

I get password prompt, I put correct password, then get such prompt:

    /ssh:username@hostname:/some/existing/dir $

Here I try to "ls -la" and get the following error:

    Couldn't find a POSIX `id' command



Best regards,
Andrey.
