• University of Toronto ☛ On not automatically reconnecting to IPMI Serial-over-LAN consoles

  One of the things that the IPMI (network) protocol supports is Serial over LAN, which can be used to expose a server's serial console over your BMC's management network. These days, servers are starting to drop physical serial ports, making IPMI SOL your only way of getting console serial ports. The conserver serial console management software supports IPMI SOL (if built with the appropriate libraries), and you can directly access SOL serial consoles with IPMI programs. However, as I mentioned in passing in yesterday's entry, IPMI SOL access has a potential problem, which is that only one SOL connection is allowed at a time and if someone makes a new SOL connection, any old one is automatically disconnected. This disconnection is invisible to the IPMI SOL client until (and unless) it attempts to send something to the SOL console, at which point it apparently gets a timeout. This is bad for a program like conserver, which in many situations will only read SOL console output in order to log it, not send any input to the SOL console.

  • HowTo Forge ☛ Linux last Command Tutorial for Beginners (8 Examples)

    The Linux last command is a useful utility that provides detailed information about the most recent logins to the system. By querying the system's log files, specifically /var/log/wtmp, it displays a comprehensive list of user sessions, including the username, terminal name, IP address (if applicable), and the time and duration of each session. This command is particularly valuable for system administrators to monitor user activity, track login attempts, and identify unauthorized access. Additionally, last can be customized with various options to filter results, such as showing only a specific user's logins or displaying entries from a particular date range, making it a versatile tool for system management and security auditing.

    If you are new to system administration, you may need to access or monitor credentials. You will probably use several tools for this purpose, and one of them is last. In this tutorial, we will explain the basic functions of this program with some easy-to-understand examples.

• Tom MacWright ☛ Reverse engineering a day’s worth of websites

  Some light reverse-engineering of websites has been a source of entertainment and knowledge for me. I’ll poke around in the Chrome DevTools and figure out the basics of how popular websites work.

  Sure, it’s common to compress JavaScript and other resources, and the HTML source of webpages no longer give many hints for technology – long gone are the days of having a meta name=generator tag that revealed your tech stack. But it’s pretty easy to suss out the major tech involved and reading obfuscated source isn’t too bad. The more you practice the easier it is to notice the patterns.

  Here’s some of what I look at in a day, with some quick reverse-engineering applied. It’s interesting to get a sample of these applications, the ones that I use on a daily basis.
