ssh-rsa passwordless login not working
When connecting to DocEvent servers using sftp and using an ssh-rsa key for passwordless authentication, you might still be asked for a password.
% sftp -i ~/.ssh/id_rsa email@example.com firstname.lastname@example.org's password:
The expection is that the login should be passwordless. But a password was requested!
If you execute the command with the -v parameter like so, you'll get more output, and possibly a message saying no mutual signature algorithm. For example:
% sftp -v -i ~/.ssh/id_rsa email@example.com ... snip ... debug1: Offering public key: ~/.ssh/id_rsa RSA SHA256:snip explicit agent debug1: send_pubkey_test: no mutual signature algorithm
If this is the case, most likely your client is not working with ssh-rsa connections, and you need to modify your ~/.ssh/config file and add the following:
Host *.docevent.io PubkeyAcceptedAlgorithms +ssh-rsa
Note that the indentations are both tabs. This should fix the issue.
