[Xen-users] Can not establish a SSH Connection into Dom0

Hello everyone,

I own a small network: Three 'normal' Computers (Win or Debian) and a Xen 3.02 
(Debian) installation with three DomU's. SSH between the Computers works fine 
with one exception: I can establish a SSH connection from the DomU to the 
'normal' Computers and to Dom0 but I can not establish a SSH connection from 
Dom0 (or from a 'normal computer') INTO DomU. It is also not possible to 
establish a SSH connection between the DomU's

I searched a lot, modified my Xen several time but still have no idea where the 
problem could be. When I try to connect with SSH to a DomU the message alway 
is: "Read from socket failed: Connection reset by peer"

I run some services on the DomU's: At the moment a Samba server and a VPN 
Server and all services are working fine.

Then I reinstalled the SSH several times, everytime with deleting /root/.ssh/ 
and /etc/ssh/. For my DomU's I use the 

following mac adresses: AA:00:00:00:00:20, AA:00:00:00:00:21 and 
AA:00:00:00:00:22. I also tried to run the DomU's with random macadresses like 
00:16:3E:4E:76:E5. At last, I installed another ethernetcard into my computer, 
hide the ethernetcard from Dom0 and used it with its real macadress in a DomU 
and told SSHd to listen on this card. 

Nothing helps.

My entry in the xend-config.sxp is:

(xend-relocation-server yes)
(xend-relocation-hosts-allow '^localhost$')
(network-script network-bridge)
(vif-script vif-bridge)
(dom0-min-mem 196)
(dom0-cpus 0)

'brctl show' shows me:

                                                        vif3.0

and a ifconfig in Dom0 shows me:

Has anyone an idea, what should I modify as next? The computer, on which Xen is 
running, is an old IBM Netfinity 

with 2GB Ram and and some Ethernetcards.

Thank you in advance for every Tip,
