Cisco Catalyst 9400 Series
Cisco’s Catalyst 9400 Series introduced this summer do look promising, but it’s still missing a few highlights: Complete support for redundant supervisors; unavailable according to the release notes dated July 31, 2017 The supervisor module (hardware) supports redundancy, but the software does not. The associated route processor redundancy (RPR) and stateful switchover (SSO) features are […]

I created a shell script which began its simple life as After running the script for a second time and a third time, etc, the script was successively changed to: Restart Apache using service apache24 restart. In the end, PHP 7.0.22 got upgraded to PHP 7.1.9. All is well.

A student experienced Revit 2018.1 giving him this rather useless error message: Licensing System Error 1 After Googling for a solution, we installed/repaired all the Visual C++ runtimes we could find in 3rdParty\x64\VCRedist and in 3rdParty\x86\VCRedist from the Revit 2018 distribution. Success! Shame on lazy developers not willing to code reasonable error messages explaning what […]

Yesterday, a student installed Autodesk Revit 2018 on his Windows 10 x64 laptop. He then upgraded to Revit 2018.1. After entering the licensing details, Revit crashed. Installing the latest drivers from nVidia, currently at version 385.41, and rebooting the laptop saved us from any more grief.

I’ve been exploring Pässler PRTG on Microsoft Windows Server 2016 (Microsoft Imagine Premium) for the past couple of days. While the system is impressive and on the border of being overwhelming, it lacks complete IPv6 support. The web interface is IPv4 only, and the NetFlow v9 collector only understands IPv4. PRTG can do PING, SNMP, […]

ocserv and user-profile=profile.xml
Running OpenConnect’s ocserv with user-profile=profile.xml creates some headache as all files are removed from /var/run at reboot. Enabling ocserv_prep in /etc/rc.conf and adding this shell script solves that problem.

Adventures on ESET NOD32
I decided to upgrade ESET NOD32 from 10.0.390.0 to 10.1.219.1 using the dashboard. Huge mistake! My computer lost network connectivity and only a few programs ran successfully. Even uninstalling NOD32 was partially successful. Prior to 10.0.390.0, I ran NOD32 9.0.386.0. I was able to download a removal utility and a new installer. I booted into […]

One of our Dell Latitude E7240 exhibited strange mSATA SSD behaviour. Disk requests didn’t complete on time. This computer ran the A13 firmware. The case was eventually solved by upgrading to the A21 firmware executed from an USB stick as the mSATA SSD was unreliable at this point. Apparently, the A18 firmware corrected some mSATA […]

After a couple of crude attempts at making my own versions of namei(1) this spring, namei.c and namei.go, I decided to take a look at the original. My goals were to see if I had made any mistakes, and if possible, have the original properly working on FreeBSD.
