Trouble to log in into s390 developer machines

[Andreas Tille <tillea@rki.de>]

Hi,

at http://db.debian.org/machines.cgi  the hosts raptor and trex are listed
as s390 developer machines.  I wanted to build the package phylip which has
to be builded manually because it is in non-free.

$ ssh -i ~/.ssh/my_key tille@raptor.debian.org
ssh_exchange_identification: Connection closed by remote host
$ ssh -i ~/.ssh/my_key tille@trex.debian.org
tille@trex.debian.org's password:

For security reasons I have no passwort on any developer machine and
use ssh-key authentication exclusively.

Any hint how to log in on any s390 machine with chroots to build the
package?

Kind regards

           Andreas.
