you can try the following:
- first, i presume you already have the public key generated inside the ~/.ssh/id_rsa.pub on your local computer
- now, you should have a string in that file sort of the one like I have: "ssh-rsa AAAAB3Nz………………..lWUpb3Uw/nQRBc= mike@Mikhail.local"
- copy the string into clipboard
- now, log into remote server (entering the password, as usual). there should be a directory called ".ssh" inside your home directory. now, check if you have a file called "authorized_keys" inside that directory. if you don't have it, create one. or edit the existing one. What you need to do is to add the public key contents which you copied into clipboard on step 2, as a new line to the "authorized_keys" file contents.

basically, this approach should work for you. I have a server on which the ssh-installkeys doesn't work as advertised, so for that case I use the approach I have wrote about about. hope it works for you too.

But unfortunately it doesn't work at my site. I assume this has to do with ssh configuration?!

Maybe anybody can tell me how to configure ssh so this magic works. Are there some global or local ssh settings that have to be adjusted so this works? Maybe in /etc/ssh/ssh_config?

Any help appreciated! Thanks!

I am one of the super lazy people, so I must point out that your ssh command has 8 characters too many :)

Instead of "ssh myself@someserver.com", you can just do "ssh someserver.com". To configure this magic, edit ~/.ssh/config and add your user id that you want to use for that server:

Host someserver.com
User dave
