Setting up the labs from Michael Jang's book

Reddit - Thu, 2016-04-21 21:21

I am not good with networking, and need some help with setting up the lab from chapter one in Jang's new 7th edition book.

Three virtual machines:

systems on the example.com domain will be configured on the 192.168.122.0/24 network.

systems on the example.org domain will be configured on the 192.168.100.0/24 network.

server1.example.com is 192.168.122.50

tester1.example.com is 192.168.122.150

outsider1.example.org is 192.168.100.100

The networking on my machine is on the private subnet of 10.100.1.0. I need to be able to create virtual machines that will be able to communicate with the public network for updates and installations, but they also need to be able to communicate with each other.

Any guides available to help through this? I am at a loss.

So, is Ubuntu's new Snappy packaging basically a proprietary system?

Reddit - Thu, 2016-04-21 18:41

As I understand it, Canonical not only isn't publishing the server software to host your own snap repository, but also doesn't provide any way for users to add a third-party snap repository. So if you want to publish snaps for Ubuntu, you have to publish them on Canonical's servers. Is it true or am I missing something?

Redox is getting bigger and I think the mods should place a link to /r/redox/ under Other operating systems block in sidebar.

sending from different accounts using ssmtp (or a diff tool)

Reddit - Thu, 2016-04-21 17:32

I use SSMTP to send emails via Gmail from my Ubuntu server. I'd like to schedule a cron job to send an email from a different gmail account, which doesn't have a local account on my server.

So a few questions -

  1. Can this be done?

  2. Is my ssmtp config set up right? I have it in /etc/ssmtp/ssmtp.conf. So wouldn't this mean any account would be sending as my primary gmail account, rather than a different gmail account for each user account. My config is below

Thanks

root=xxxxx@gmail.com mailhub=smtp.gmail.com:587 AuthUser=xxxxx@gmail.com AuthPass=xxxxx UseTLS=YES UseSTARTTLS=YES rewriteDomain=gmail.com hostname=localhost submitted by /u/Bad_Eugoogoolizer

Why is `super + i` the new terminal window shortcut key in Terminator and not something more conventional like `ctrl + n`?

Reddit - Thu, 2016-04-21 17:03

Why is super + i the new terminal window shortcut key in Terminator and not something more conventional like ctrl + n? Is there some ancient Linux Lore behind this? Seems like a very strange keyboard combination to someone who has only been using linux for a couple years. http://linux.die.net/man/1/terminator
