Look at your ops435-first instance details and find its automatically-assigned public IP address. Connect to it with SSH. Note that you need to user your private key to connect, and since it doesn't have a default name nor is it in the default location for SSH keys: you need to specify the path to it manually. The default username on Amazon Linux is '''ec2-user'''. [[File:AWSFirstSSH.png|800px|border|center]]
You have at least one semester's worth of experience of CentOS, so look around to see if anything looks different from what you're used to. For example:
*Many packages not installed by default in the Minimal installation of CentOS (e.g. net-tools) ''are'' installed by default in Amazon Linux. I like to also install telnet and nmap.* * Note that Amazon Linux has its own package repositories: '''/etc/yum.repos.d/amzn2''', but the yum/rpm commands work the same as in CentOS.* The systemctl command to control your services works the same way as in CentOS.* Note neither iptables nor any other firewall is installed by default. It is in CentOS.* You user information files ('''/etc/passwd''', '''/etc/shadow''', '''/etc/group''') are used in a completely standard way.* Have a look at the output of '''netstat -atnp''' and '''netstat -coreaunp''' to see what ports services are listening on in a default installation.repo
