debian.org Developer Machines
SSH Host Keys
The SSH host keys for the machines in the debian.org domains are stored in the Debian LDAP database. The key and its fingerprint will be displayed when details for a machine are displayed.
Developers that have a secure path to a DNSSEC enabled resolver can
verify the existing SSHFP records for the debian.org servers by adding
VerifyHostKeyDNS yes to their ~/.ssh/config
file.
On machines in the debian.org which are updated from the LDAP
database /etc/ssh/ssh_known_hosts contains the keys for
all hosts in this domain. This helps for easier log in into such a
machine. This is also be available in the chroot environments.
Developers should add StrictHostKeyChecking yes to
their ~/.ssh/config file so that they only connect to
trusted hosts. Either with the DNSSEC records or the file mentioned
above, nearly all hosts in the debian.org domain will be trusted
automatically.
Developers can also execute ud-host -f or
ud-host -f -h host on a machine in the debian.org domain
in order to display all host fingerprints or only the fingerprints of
a particular host in order to compare it with the output of
ssh on an external host.
