1 -> 16) Review of EX200 Concepts

• See EX200

17) Managing IPv6 Networking

• When specifying IPv6 Address w/ port, use this format: [2001:db8:0:10::1]:80
• /64 is standard IPv6 subnet mask (but providers generally use /48)
• Important IPv6 Addresses:
• ::1/128 => localhost (equivalent to 127.0.0.1/8)

通过ubuntu的apt-get安装的squid没有启用ssl功能，需要手动编译。

编译squid步骤如下。

Notes from my mastodon test instance config.
Assumptions: you own some domain-name and its pointing to the ip of this instance. I'm calling it my.domain
This may or may not work for you. I've moved notes around so things might break.
I'm basically just doing config as described here:
https://github.com/tootsuite/documentation/blob/master/Running-Mastodon/Production-guide.md

# Start: I'm creating the machine on DigitalOcean.
# You can probably skip this part ( 9.)
### DigitalOcean guest creation ###
1.#create digitalocean host. 10$ (non-zfs freebsd host) i did this on a 5$ but upgraded later.

RHCSA Review Sheet

====================

1) Local & Remote Logins

• SSH
  • ssh-keygen => create public + private key pair
  • ssh-copy-id => easy way to copy key to correct location in remote system
    • I.E. 'ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]'
  • ssh-agent => prevents you from having to re-enter a password protected key multiple times
  • ssh-add => adds private key identities to the authentication agent
