Azure DevOps, ssh-rsa, openssh

I wasn't able to git fetch from Azure DevOps repos after upgrading openssh on my computer.

ssh -V
  OpenSSH_8.8p1, OpenSSL 1.1.1l  24 Aug 2021

Turns out that OpenSSL has now turned off ssh-rsa by default:

This release disables RSA signatures using the SHA-1 hash algorithm by default.

But Azure DevOps doesn't support anything else... Add the following to your config file to re-enable ssh-rsa for Azure DevOps:

Installing Homenet on LEDE/OpenWrt (DRAFT)

Installing Homenet on your Router

This set of instructions configures a fresh LEDE installation to run Homenet. They will likely work on a current build of OpenWrt.

There's lots of good info about Homenet elsewhere. See the External References section (below).

The general strategy is to connect your computer to the router's LAN Ethernet, convert the wireless and WAN interfaces to run Homenet, and test the changes so far. After things are working, configure the LAN Ethernet to Homenet through connect one of the (now Homenet) wireless interfaces.

  1. Install LEDE on your router. See the main Getting Started with LEDE page for details.

Exposing a directory on the host machine to an LXC container #blog

Exposing a directory on the host machine to an LXC container

  1. Log into the container and create an empty directory, this will be the mount point
  2. Log out and stop the container.
  3. Open to your container's config file
    • For regular LXC containers: /var/lib/lxc/mycontainer/config
    • For unprivileged LXC containers: $HOME/.local/share/lxc/mycontainer/config
  4. Add a new line above the lxc.mount directive, that follows the format below. Substitute proper paths as necessary:
    • lxc.mount.entry = /path/to/folder/on/host /path/to/mount/point none bind 0 0
  • Both of these paths are relative to the host machine.
