Unable to connect to server using openssh private key

I cannot connect using my private key:

I can confirm that this is happening to me too. Selected my key under ~/.ssh/id_rsa

Thanks for reporting, will look into it

I've had the same problems today with some of the servers I manage. I tested on one of my servers by changing to a different key from another server that worked and the problem resolved - the difference between the two keys being the length of the key. Perhaps a clue into the source of the problem?

Related issue dbeaver/dbeaver#5845, consider using/supporting SSHJ.

Temporary solution:

private key generated by ssh-keygen starts with

-----BEGIN OPENSSH PRIVATE KEY-----
and not
-----BEGIN RSA PRIVATE KEY-----

To generate supported key add -m PEM to the end of your ssh-keygen command

e.g.

ssh-keygen -m PEM

This works with version 1.0.4

Can confirm this is still an issue to date. Existing OpenSSH private keys can be converted to RSA format using the following terminal command where id_rsa is the OpenSSH private key:

ssh-keygen -p -m PEM -f ~/.ssh/id_rsa

Recommend you back-up id_rsa before running the command as the file will be overwritten when converted. Remember to chmod 600 id_rsa or it will be ignored.

OpenSSH seems to be the new standard private key format. Any comment on when/if Snowflake will add support?

Thank you for this program.

Using Snowflakes for connecting to AWS EC2 unable to connect through .pem files for the new EC2 instances ( through Putty/WINSCP i can login to EC2 with same key). But can connect to Older EC2s with Snowflake with their .PEM files.
Please help.

[Devoscope]

facing the same issue while I am trying to access the new aws instance, i 'm geting an error - Unable to connect to server.

Please look into this.
