adding the second keys pair to .ssh

student975 · 2016-06-11 11:50:48

Hi!

I have placed the second ssh keys pair as ~/.ssh/identity[.pub]. Also, I use enabled/running gpg-agent service (with --user flag) with SSH support. After logging in to be able to use the second pair I must invoke ssh-add <path to key> and restart gpg-agent.

So, the question is: how to configure all this mechanics to avoid manual manipulations?

man ssh_config

There are a couple of examples in the wiki too.

I have tried ~/.ssh/config containing

Host *
     IdentityFile ~/.ssh/id_rsa ~/.ssh/second

without success. As well as

Host *
     IdentityFile ~/.ssh/id_rsa
     IdentityFile ~/.ssh/second

It parses from the top of the file, taking whatever the first match for "Host" is. Since you have Host * that will match everything. You need a more specific Host for the first entry and then either a second specific one or a general one. Ex:

Host 10.0.0.1
IdentityFile ~/.ssh/ssh_auth_1

Host 10.0.0.*
IdentityFile ~/.ssh/ssh_auth_2

Host *
IdentityFile ~/.ssh/ssh_auth_general

Thanks!

At the moment I'm just forced to restart gpg-agent. It seems the last one starts (with --user) too early, and some "After" (or what) must be added to .service file.
