I have set Webmin > Servers > SSH Server > User SSH Key Setup > Setup SSH key for new Unix users set to Yes.
I also have Virtualmin > System Settings > Virtualmin Configuration > Action upon server and user creation > Notify other modules when updating server administrator Unix users set to Yes because I read in another support request that this was required.
Still, I am not getting any SSH keys created for the admin user when I create a new virtual server. I know how to do it manually, but would like to have it done automatically. Also, is there anywhere to set the default key size?
