Lab Activity Duration: 3-4:20pm

General description

In this lab students were introduced to systemd to create a mechanism to upload their script to GitHub upon boot.

<aside> 💡

[REMINDER] Students cannot be in C037 alone (or with Koray) so we will end the labs promptly at 4:20 (huh huh) pm every Thursday.

Successful Groups [Things that Went Well]

All groups got a systemd file that was written in a way that it would work—though some were not working because the .sh script was improperly configured

Questions that Arose

Q. Where is systemd?

A. /etc/systemd is most optimal. /lib/systemd/system, /usr/lib/systemd/system are for things relating to packages rather than sysadmin-related settings

Q. what should be permissions?

sudo chown student334:student334 /path/to/file

sudo chmod 744 /path/to/file

• run systemd as student334

Q. Can we use .bashrc or rc.local?

A. maybe? But you can’t open terminal if you don’t know IP and you want to make sure it runs after network is setup, so this isn’t a great idea

Problems & Solutions

• Would run successfully, but wouldn’t upload. Related to an inability to reach github.com. This is because After: [network.target](<http://network.target>) was used instead of After: network-online.target .
• Would not run the file: File must have correct owner and mode (see Q&A), and set User=student334
