loginproblem using the pserver-method

[rhelms]

Hi,

I have start a new setup from the cvs-server. After creating the passwd-file in
CVSROOT   I try to login with 
cvs -d:pserver:address@hidden:/usr/local/newrepos login
would asked for a password
and get the message

cvs [login aborted]: recv() from server linux: Die Verbindung wurde vom
Kommunikationspartner zur?ckgesetzt                                            
        get the message

When I try to login from my W2K-box via wincvs it failed and say that I first
to setup passwordauthentication in the preferences. Here I use ssh   via 
plink.exe (putty)  and  use pserver with port 2401.

Whats getting wrong?

Ruprecht
