how to build json from cli

we all like json, do we ? https://kellyjonbrazil.github.io/jc/docs/parsers/ping

add package

doas pkg_add jc

try ping

Compatible platforms: linux, darwin, freebsd -> had to redirect the stderr to /dev/null because OpenBSD is not (yet) supported officially…

Assume you got a fresh Machine with DHCP …

Ubuntu with DHCP Config

cat /etc/netplan/01-netcfg.yaml
# This is the network config written by 'subiquity'
network:
  ethernets:
    ens192:
      dhcp4: true
  version: 2

and you’d like to switch to Static IP, ask google how todo it an give try:

Static IP with Netplan

# This is the network config written by 'subiquity'
network:
  version: 2
  ethernets:
    ens192:
      addresses:
      - 1.2.3.4/24
      gateway4: 1.1.1.1
      nameservers:
        addresses:
        - 8.8.8.8
        - 8.8.4.4
        search:
        - world.net

then reboot … and the machine is gone. ok, not really gone, but from IP perspective definitly. it just reboots and come back without default gateway :(

bhyve, pronounced “beehive” is a hypervisor/virtual machine manager for FreeBSD that supports most Intel and AMD processors that report the “POPCNT” (POPulation Count) processor feature in dmesg(8).

Download ISO and boot it

… in a new Virtual Machine …

cat << 'EOF' > run_bhyve.sh
#!/usr/bin/env bash

iso=FreeBSD-13.1-RELEASE-amd64-bootonly.iso
vm=guest.img

# Load Module if needed
kldstat |grep vmm.ko || kldload vmm

ifconfig tap0 create
sysctl net.link.tap.up_on_open=1

ifconfig
ifconfig bridge0 create
ifconfig bridge0 addm vmx0 addm tap0
ifconfig bridge0 create
ifconfig bridge0 up

# Get ISO
test -f $iso || fetch https://download.freebsd.org/releases/amd64/amd64/ISO-IMAGES/13.1/$iso

# Prepare Disk File
test -f $vm || truncate -s 16G $vm

# Boot from ISO
sh /usr/share/examples/bhyve/vmrun.sh -m 1024M -t tap0 -d guest.img -i -I $iso vm001

exit 0
EOF

Set Permission and run it

chmod 700 run_bhyve.sh
./run_bhyve.sh

-> Run Live System or install a brand new System

Upgrade FreeBSD 13.0 to 13.1

should be a easy task, right ?

Patch it first

freebsd-update fetch
freebsd-update install

reboot

may not needed, but you have to boot anyway a few times …

Fetch and Upgrade to 13.1

this needs some time ! depending on your internet speed, and specially to power and filesystem performance of your machine. 20-30min for a common VM is not unreal :(

time freebsd-update upgrade -r 13.1-RELEASE
time freebsd-update install

Reboot

shutdown -r now

Finish Install

freebsd-update install

Final Reboot

shutdown -r now

Any Comments ?

Background

It seems as OpenBSD (and the installed Software) is useing more and more Space in the /usr Partition. For Upgrading to 7.1, at least 1.1 GB Free Space is needed. So, i’m gooing to update my Default Partitioning Proposal like this:

Example with 25 GB

root@puffy# df -h
Filesystem     Size    Used   Avail Capacity  Mounted on
/dev/sd0a      3.9G    766M    2.9G    20%    /
/dev/sd0d      1.9G   20.0K    1.8G     0%    /tmp
/dev/sd0e      5.8G   36.1M    7.3G     0%    /var
/dev/sd0f      7.8G    3.6G    3.8G    49%    /usr
/dev/sd0g      2.xG    150M    7.2G     2%    /home

which results in this:

a 4G  /
a 2G  swap
a 2G  /tmp
a 6G  /var
a 8G  /usr
a *   /home

Example with 32 GB

root@puffy# df -h
Filesystem     Size    Used   Avail Capacity  Mounted on
/dev/sd0a      3.9G    766M    2.9G    20%    /
/dev/sd0d      1.9G   20.0K    1.8G     0%    /tmp
/dev/sd0e      7.8G   36.1M    7.3G     0%    /var
/dev/sd0f      7.8G    3.6G    3.8G    49%    /usr
/dev/sd0g      7.7G    150M    7.2G     2%    /home

which results in this:

a 4G  /
a 2G  swap
a 2G  /tmp
a 8G  /var
a 8G  /usr
a *   /home

Custom HTTP method, HTTP headers and JSON data:

we all do like aliases, right ?

https://git-scm.com/book/en/v2/Git-Basics-Git-Aliases

Some Aliases

git config --global alias.co checkout
git config --global alias.br branch
git config --global alias.ci commit
git config --global alias.st status
git config --global alias.bra "branch -a"

and then, you just type:

git co
git br
git ci
git st
git bra

.gitconfig

all this stuff is saved in ~/.gitconfig

$ cat ~/gitconfig
# This is Git's per-user configuration file.
...
[alias]
  co = checkout
  br = branch
  ci = commit
  st = status
  bra = branch -a
