  • Chrooted SFTP, Inotify & Chattr – A Fortified Prison for Backups

    Posted on June 3, 2019 by Comment

    In my last post, I touched on ways you could automate remote database backups using SSH and passphrase-less keys. I didn’t really go in-depth as I felt this topic deserved its own article and wouldn’t you know it, here it is!

    Now, as you can tell by the title, we’re going to be focusing on using SFTP as our transfer protocol of choice instead of SSH or SCPas I’ve found its a lot easier to sec ...

  • Microsoft Edge Hates My Intranet Sites

    Posted on January 14, 2019 by Comment

    Trust No OneRecently, I noticed that this very site, Labsrc.com, wouldn’t load in Microsoft Edge. On my Windows 10 PC, I was able to open the site in every other browser, Firefox, Chrome, IE, etc., except Microsoft’s successor to Internet Explorer. I initially started worrying that there was some change I made that was causing Edge to hang and that all my Microsoft readers were crashing their browsers bec ...

    Posted on July 22, 2016 by Comment

    A couple months ago, a customer of mine was kind enough to donate some decommissioned Cisco Catalyst 3750G’s to me. I was happy to accept them as my test lab was growing in size and I had the need for multiple network segments. With the switches capable of doing Etherchannel, VLAN Trunking & Stacking I finally had a large-scale network infrastructure which in all honesty is probably overkill f ...

    Posted on April 25, 2016 by 4 Comments

    If you’ve connected a computer to the Internet, you’ve probably heard of an IP address. Most people, however, quickly gloss over IP’s little brother, the often forgotten and sorely misunderstood, Subnet Mask. You’ve seen him, but probably never knew his name. He usually looks like this.

    While this is the Subnet Mask you’ll most often see, you may run into others that look very differ ...

  • Awesome Linux Command-Line Tools – Network Edition

    Posted on March 31, 2016 by Comment

    Here’s a list of Network tools for the Linux admin whose only resources are a keyboard, a terminal and whatever brains they can muster. No GUI’s here people. These are all tools I’ve found invaluable or at the very least, super cool to play with. Who hasn’t watched movies like The Net or Live Free or Die Hard and thought, “That’s awesome. I wanna do that.” Pwn with the terminal I mean, not ...
