LCD brightness setting on NetBSD

If you have an operating ACPI subsystem, give this a try to set your screen brightness:

1. Check the actual value:

# sysctl -a | grep bright

2. Set the relevant sysctl parameter. Mine looks like this (default value is 100):

# sysctl -w hw.acpi.acpiout1.brightness=110

Updating GitHub forked repository

Quote from stackoverflow.com:

# Add the remote, call it "upstream":

git remote add upstream https://github.com/whoever/whatever.git

# Fetch all the branches of that remote into remote-tracking branches,
# such as upstream/master:

git fetch upstream

# Make sure that you're on your master branch:

git checkout master

# Rewrite your master branch so that any commits of yours that
# aren't already in upstream/master are replayed on top of that
# other branch:

git rebase upstream/master

Installing CA Certificates into NetBSD

Submitted by Fekete Zoltán on Mon, 01/23/2017 - 08:00

1. Download the CA certificate in PEM format

If  it was not available in PEM, then determine which format it is (here: DER), then convert it:

$ openssl x509 -in ca-cerificate-file.crt -inform DER -out ca-cerificate-file.pem -outform PEM

2. Check the fingerprint

$ openssl x509 -noout -fingerprint -in ca-certificate-file

3. Copy the CA cert frile into /etc/openssl/certs folder 

Then cd there.
