Hi,
I have a Tumbleweed system which makes a backup each night to a Leap 15.4
system, both use aarch64 architecture. I use publickey for authentication,
which worked until recently. Both are up-to-date with the latest updates.
On the Tumbleweed system I have:
# ls -l .ssh/id_*
-rw------- 1 root root 1381 21 feb 12:34 .ssh/id_dsa
-rw-r--r-- 1 root root 608 21 feb 12:34 .ssh/id_dsa.pub
On the Leap 15.4 system I have:
rpi4-154:~ # ls -l .ssh/authorized_keys
-rw------- 1 root root 2962 feb 21 12:39 .ssh/authorized_keys
with the content of id_dsa.pub.
The start of the content is:
ssh-dss AAAAB3NzaC1kc3MAAACBAIxtorhRWGDeP6L01o83+LgSL9DYcYAXozXtl1cknkfbO
To test the way the connection is made I give the command:
ssh -v -p xx root@
Which gives me debug output.
After negotiation for the ssh connection the output shows the start of the
publickey negotiation, which immediately starts with:
debug1: Skipping ssh-dss key /root/.ssh/id_dsa - corresponding algo not in
PubkeyAcceptedAlgorithms
A few lines further on I have:
debug1: kex_input_ext_info: server-sig-algs=
in which ssh-dss is present.
It goes on with:
debug1: SSH2_MSG_SERVICE_ACCEPT received
debug1: Authentications that can continue: publickey,password,keyboard-
interactive
debug1: Next authentication method: publickey
But then a number of "debug1: Trying private key: /root/.ssh/id_*"
where id_dsa is not present.
It continues with:
debug1: Next authentication method: keyboard-interactive
So it asks for a password and authorization with publickey no longer works.
Previously I tried "ssh-keygen -t ecdsa" which did not work either and the one
that I used, which worked, was of the type rsa.
Any ideas? Bug?
