Technical guide for using YubiKey series 4 for GPG and SSH

YubiKey 4 series GPG and SSH setup guide

root@bastion:~# find /tmp/ssh-* -type s
/tmp/ssh-srQ6Q5UpOL/agent.1460

root@bastion:~# SSH_AUTH_SOCK=/tmp/ssh-srQ6Q5UpOL/agent.1460 ssh user@internal.company.tld

user@internal:~$ hostname -f
internal.company.tld
