Reading manga on Kobo

The .cbX formats

I like to use the .cbz format to read manga because it’s very simple. It’s just a .zip file containing the images for the manga pages with its extension changed to .cbz . (There’s also .cb7 and .cbr that use 7z or RAR archives.) Images are read in alphabetical file name order by the e-reader and displayed on screen. That’s just it.

cron-like systemd unit

1. Create myunit.service. Only [Service] is needed, with an ExecStart=

2. Create myunit.timer. It needs [Timer] with an OnCalendar= or similar. It needs [Install] with WantedBy=timers.target

3. Enable both units. The .service unit will issue a warning due to missing [Install]. This is not a problem

    systemctl --user enable $PWD/myunit.service
    systemctl --user enable $PWD/myunit.timer

MSMQ Nmap service probe

⚠️ Disclaimer: testing of this probe is limited and the MSMQ protocol is proprietary and undocumented. Use this probe at your own risk. ⚠️

Nmap currently has no way to detect whether the service running on TCP port 1801 is [Microsoft Message Queuing (MSMQ)][wikipedia_msmq]. The file msmq-service-probe here has been developed to give Nmap the capability to detect MSMQ. The objective is to help identify assets with MSMQ exposed, that may be vulnerable to [CVE-2023-21554][nist_cve_2023_21554], aka QueueJumper.

This works by sending a MSMQ packet to port 1801 and checking if the response matches an expected fingerprint.

You can run this probe as follows:
