#24928 Problems accessing SSH host key

[Dietmar Lippold]

I login into the shell server and remotely execute commands on the shell server by using SSH public key authentication.

For login I use the following command:

ssh -t dlippold@shell.sourceforge.net create

Since 17. August I get the following error message when I try to login or execute a command from remote in about half of the cases:

You already have a shell created.

could not open any host key
ssh_keysign: no reply
sign using hostkey ecdsa-sha2-nistp256 SHA256:W5Aer0OjESVt5fbduA9o7/XUeTdmi8arcwhjmVaGbzs failed
dlippold@10.60.22.229's password:

Here is the output with an additional option "-v" for ssh:

...

And here is the output of a successful login for comparison:

...

debug1: Sending env LANG = de_DE.UTF-8
debug1: Sending command: create

You already have a shell created.

This is an interactive shell created for dlippold.
Use the "timeleft" command to see how much time remains before shutdown.
Use the "shutdown" command to destroy the shell before the time limit.
For path information and login help, run "sf-help".
