Hi,

on my server, I am running lsh-server 2.1-12 and trying to connect via OpenSSH_8.2p1 on client side.

On server, a user with passwordless sudo exists.

--------------------------- user ALL=(ALL) NOPASSWD:ALL ---------------------------

From client side, I try (in different combinations)

$ sshpass -p xxx ssh -t -i /tmp/test_id_rsa.pub -o KexAlgorithms=diffie-hellman-group1-sha1 -o Ciphers=aes256-cbc user@$server 'sudo shutdown -h now'

I have to mention, that an ssh-copy-id with...

$ sshpass -p xxx ssh-copy-id -i /tmp/test_id_rsa.pub -o KexAlgorithms=diffie-hellman-group1-sha1 -o Ciphers=aes256-cbc user@$server

...seems not to work, too.

What I get:

[sudo] password for user:

or

sudo: a password is required

or

sudo: no tty present and no askpass program specified

Does someone in the group have the knowledge hot to connect correctly?

Many thanks! Will Code
