SSH

Troubleshooting

When using a pretty old ssh client, there is a possibility you cannot connect to the sshd anymore.

For debugging purposes you should set following parameter in your sshd_config and restart it.

LogLevel DEBUG

If following error occurs when debugging

userauth_pubkey: key type ssh-rsa not in PubkeyAcceptedAlgorithms

you should set the parameter in sshd_config

PubkeyAcceptedKeyTypes=+ssh-rsa
