System Management with egress firewall filtering

in flag

I have a contractor that manages firewall and security. They are moving to egress web filtering. I am all for security, but I have a few months to make sure that this does not break my toys...systems. I need IP addresses for the sites that I access. Currently, I have a linux computer lab, two physical servers, and multiple VMs. Ironically, the strength of this community is that you can learn how to make your own anything. So my search for IP ranges has been interesting. What IP addresses do I need to white list to use Ubuntu Desktop, Server 20.04, and the repositories related to them?

Thank you.

Use the `ss` command (see `man ss`) on each port to list the ports that each system uses. Advice: During implementation, plan to have physical access to each device.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
