Adding a DHCP Firewall Rule

Note: This firewall rule will restrict your computer to only conduct DHCP exchange with a designated IP. If you move to another network and rely on DHCP, you will need to remove this rule for your DHCP to work properly

Open the Windows Security Center:
- Press the Windows key + I to open the Settings app.
- Navigate to "Privacy & Security" and then select "Windows Security".
Access the Firewall & network protection settings:

Encrypt:

tar -cJvpf - inputdirectory/ | gpg --symmetric --cipher-algo aes256 | split -d -b 100m - outputfile.tar.xz.gpg

Decrypt:

Sometimes you need to troubleshoot and inspect the details of jobs (load, query etc.) in BigQuery. Inspecting the job history in the BigQuery web UI will only show the jobs that you have run. This is also true when you run run bq ls -j on the command line.

But, what if you need to get all jobs that have been run? An example would be auotmated jobs run by service accounts. A quick tip is to use the --all flag:

-a,--[no]all: Show all results. For jobs, will show jobs from all users. For datasets, will list hidden datasets. For transfer configs and runs, this flag is redundant and not necessary.

bq ls -j --all
