Question

Cannot access the host to connect a database via SSH tunneling while getting "Permission denied (publickey)."

Databases

After running docker and creating an own PostgreSql database in a droplet, I can access the host via “ssh root@xx.xx.xx.xx” but I cant connect to the database via SSH tunneling. Here is the command and its response:

root@ubuntu-database:~# ssh -L 5432:localhost:5432 -N -f -l root XX.XX.XX.XX Permission denied (publickey).

I'be assigned the droplet with SSH security rather than using one-time email. Currently, I really have no idea of what is the cause of the problem -whether it’s from the droplet configuration, docker, PostgreSql setting, or SSH usage. I’m an amateur and quite new for this matter. Please kindly help.

Thank you very much.

Hi @valorvignette,

Using SSH Tunneling won’t get your SSH key automatically like using plain SSH. You’ll need to pass it down the command you use.

ssh -N -L 5432:127.0.0.1:5432-i /path/to/ssh/key root@XXX.XXX.XXX.XXX

Please don’t forget to chage both the path and the XXX. with your actual IP address.

Regads,
KDSys
