Better SSH Authorized Keys Management

Better SSH Authorized Keys Management

A seemingly common problem that people encounter is how to handle all of your users authorized_keys file.

People struggle over management, ensuring that users only have specific keys in the authorized_keys file or even a method for expiring keys. A centralized key management system could help provide all of this functionality with a little scripting.

One piece of functionality overlooked in OpenSSH is the AuthorizedKeysCommand configuration keyword. This configuration allows you to specify a command that will run during login to retrieve a users public key file from a remote source and perform validation just as if the authorized_keys file was local.

Here is an example directory structure for a set of users with SSH public keys that can be shared out via a web server:

Add SSH-Keys to Bitwarden

Before you can use Bitwarden CLI for your SSH private keys you have to add them to your Bitwarden account. Just create a normal login. The name, username and URI fields doesn't matter for my functions.

MySQL to Sqlite converter
#!/bin/sh
# Converts a mysqldump file into a Sqlite 3 compatible file. It also extracts the MySQL `KEY xxxxx` from the
# CREATE block and create them in separate commands _after_ all the INSERTs.
# Awk is choosen because it's fast and portable. You can use gawk, original awk or even the lightning fast mawk.
# The mysqldump file is traversed only once.
# Usage: $ ./mysql2sqlite mysqldump-opts db-name | sqlite3 database.sqlite
# Example: $ ./mysql2sqlite --no-data -u root -pMySecretPassWord myDbase | sqlite3 database.sqlite

You have something like "[WARNING] Could not draw graph "/var/lib/munin/cgi-tmp/munin-cgi-graph/" in your /var/log/munin/munin-cgi-graph.log ???

Check the directory permissions!

ls -l /var/lib/munin/cgi-tmp/

shows something like

drwxr-xr-x 3 munin www-data 4,0K Mär 29  2013 munin-cgi-graph/

It's a résumé, as a readable and compilable C source file. Since Hacker News got here, this has been updated to be most of my actual résumé. This isn't a serious document, just a concept to annoy people who talk about recruiting and the formats they accept résumés in. It's also relatively representative of my coding style.

Since this is on Hacker News and reddit...

  • No, I don't distribute my résumé like this. A friend of mine made a joke about me being the kind of person who would do this, so I did (the link on that page was added later). My actual résumé is a good bit crazier.
  • I apologize for the use of _t in my types. I spend a lot of time at a level where I can do that; "reserved for system libraries? I am the system libraries".
  • Since people kept complaining, I've fixed the assignments of string literals to non-const char *s.
  • My use of type * name, however, is entirely intentional.
  • If you're using an older compiler, you might have trouble with the anonymous unions and the designated initializers - I think gcc 4.4 requires some extra braces to get them working together. Anything reasonably recent should work fine. Clang and gcc (newer than 4.4, at le
