THIS PAGE IS A DRAFT, NOT A REAL COURSE PAGE
The current schedule for OPS345 is here: OPS335_Weekly_Schedule
AWS Networking
- VPCs, subnets
- Default dynamic public IP
- Default static private network/IP
- Reserving a static public IP under "Elastic IPs", cost of doing that
- VPC dashboard:
- New VPC vpc-ops345 with CIDR block 10.3.45.0/24, no IPv6
- Subnets: create a new one in vpc-ops345 named subnet-ops345, in us-east-1a, 10.3.45.0/24 (to fit inside the VPC)
- Edit subnet, enable auto-assign public IPv4 addresses
- Internet Gateway: Create ops345-internet-gateway, attach to vpc-ops345
- Create a new security group "ops345sg" in vpc-ops345 with only the SSH port open.
- Create a new VM named "router", in the new vpc/subnet.
- Follow the instructions in lab 1, except use the subnet-ops345 and ops345sg. Also create a new key called ops345-allmachines-key
- Note that "Auto-assign Public IP" is enabled by default, but don't change it.
- Wait till it starts, then go to "Elastic IPs" and associate elastic IP with router
Firewalls
- The purpose of a firewall on a server on the internet
- AWS Security Groups and iptables
IPtables setup
- iptables setup and troubleshooting, nmap
- iptables fundamentals
- Securing services that need to be publicly accessible
Port forwarding SSH
- Port forwarding SSH
