Unable to ssh into Algo created Linode

[ralphel]

My linode created by algo doesn't respond to SSH. ssh [email protected] times out, ssh -F configs/xx.xx.xx.xxx/ssh_config vpn reponds with no such file or directory, and any other combination or variation on SSH either fails or starts a debugging instance and fails when it attempts to bind to a port.

Anyone have any wisdom?

Make sure you're in the directory where you ran ./algo when you run

ssh -F configs/<server_ip>/ssh_config <hostname>

Ive figured it out and its actually a bug that I am going to proceed to report. The node that algo creates causes an issue from the upstream GRUB2 configuration that causes Linux to read disks asynchronously. I was able to fix it by switching to the latest kernel instead of the faulty GRUB2 one.

I just deployed to Linode and was able to SSH in to the instance with no problem using the command Algo printed as part of the final "Congratulations!" message.
