Had an issue where a Windows Server 2012 R2 system could not be accessed by RDP or remote management, as the network type had changed to Private (and thus the firewall wasn’t letting these connections through). File sharing was still working.
Found solution via SpiceWorks forum. Restart the Network Location Awareness service (needed to log on to system locally to do this). This triggered a redetection and the type wend back to Domain. RDP etc then worked again.
Scenario:
Dell Latitude 7490 with existing SATA m.2 SSD. We want to upgrade to larger NVMe drive (Crucial 1Tb).
First tried new drive in Startech NVMe USB enclosure (M2E1BMU31C). Downloaded Crucial cloning software (locked version of Acronis). Problem – not recognised as Crucial drive so Acronis won’t run.
Posts suggest that the new drive should be installed in the laptop first and the system booted via USB. So take current drive out and put it in a SATA USB m.2 enclosure. Attach this to USB-C port and reboot.
This doesn’t work. What does work is attaching it to a USB-A port instead. Then it boots with no intervention.
After that the disk was clones (with no reboot necessary!), the old dive disconnected and the system booted happily from the new drive.
There are a couple of GUI routes for setting the system web proxy for Windows 10 – the old control panel page (via Network and Internet – Network Options):
And the new settings style:
Note that the new style does not warn you that you may not be allowed to set the proxy – you can change the settings, but if you select another panel and then go back to Proxy your settings will be gone.
The reason for this is often that the system is configured to set the proxy at the machine level, not per-user. On domain systems this can be changed using Group policy. On standalone systems this can be changed using a registry key, located under
HKLM\Software\Policies\Microsoft\Windows\CurrentVersion\internet Settings
There is a DWORD key here called ProxySettingsPerUser (if not, create it). 0 means the proxy is set at machine level, 1 enables per-user settings.
If you change this to 1 then you should immediately be able to change the proxy settings.

If you send console output via email (like, say the output of jekyll build as part of a SVN post-commit hook script) if there are ANSI control characters in the string (e.g. colour codes) this can break things. In this case the mail command (Debian 9 default exim) was only sending text up to the first ANSI code, which meant that the jekyll build error messages (which are yellow and red) were missing.
To fix this pipe the text through ansi2txt (comes with the colorized-logs package in Debian and Ubuntu). This strips out all ANSI control codes making the string email safe.
(After this I pipe it through unix2dos to convert to CRLF line endings, as this appears to be the standard for email. On Debian this comes with the dos2unix package.)
The last line in the hook script then becomes
echo "$LOGVAR" | /usr/bin/ansi2txt | /usr/bin/unix2dos | mail -s "$REPOS_BASENAME build $REV" "$BUILD_EMAIL"
When trying to query FlexNet licenses using lmutil or similar from systems with a different DNS suffix, make sure that the license file server name contains the FDQN for the SERVER line. If not you can find that lmutils complains that the lmgrd process is not running, even though you can run the actual program with the appropriate license.
For example, with a line in the licence file like
SERVER servername 4eca3b4b8326 1055
running
lmutil lmstat -a -c 1055@servername.physics.gla.ac.uk
results in a HOST_NOT_FOUND error. Running the Client ANSLIC_ADMIN Utility gives the same error. However, ANSYS fires up as normal.
To fix this put the FDQN in the license file (refreshing the licence server afterwards!)
SERVER servername.physics.gla.ac.uk 4eca3b4b8326 1055
The lmutil queries should then work as normal.
The default terminal shell in macOS Catalina has changed from bash to zsh. Unfortunately it seems the Anaconda installer doesn’t know about this yet. To fix the install copy the section of code added by Anaconda from
~/.bash_profile
to
~/.zshrc
See this post for example.
In the previous post on this subject we used code from Technische Universität Kaiserslautern to monitor our GPUs using OMD checkmk (now checkmk raw). With some new RTX2080s installed this broke, as the nvidia-smi check doesn’t report anything for ECC errors (rather than 0, as previous cards did). The solution was to remove the ECC checking completely.
The new scripts are:
On the client system in /usr/lib/check_mk_agent/local/ (or plugins/)
if which nvidia-smi >/dev/null; then
echo '<<<nvidia_smi>>>'
nvidia-smi -q -x > /tmp/.check_mk_nvidia_smi

Don't forget to make it executable! You also need xml_grep installed.

Windows driver – IJ Network tool does allow you to input IP address eventually (Mac version does not). Conveniently our print server was on the same subnet as the printer, so it found it straight away. Driver can be installed on Server 2012 and shared, but cannot be shared as a LPD queue (as Canon don’t use a standard IP port).
Printer does function as an IPP printer, and LPD (if enabled).
On the Mac, use the IP address of the printer – it doesn’t communicate properly with the DNS name.
If the HP Universal print driver cannot automatically retrieve a printer configuration (say SNMP is blocked on the network or disabled on the device) it defaults to monochrome printing (UPD version 5.0 and newer). This can also lead to long pauses while trying to open the printer properties, as it presumably times out while trying to retrieve the data. On the Device Settings tab, click Device Type: Auto Detect to display the drop-down list and then select Color (and also check the duplex setting).
We got a ssd upgrade for a Mac (JetDrive 885) which comes with an enclosure to allow data to be copied to the new drive. This can be done with Disk Utility – as you are cloning the boot drive you need to run this in recovery mode (boot holding cmd – r). Presumably booting from a usb stick would work as well.
Once in disk utility choose the external drive, select Restore and choose to restore from the Macintosh HD. At this point we ran into an issue:
Could not change the partition type for /dev/disk1s1 - error -5342
We eventually found the problem – the new ssd had been configured with a MBR partition table, not GPT. To fix this go to the View menu and choose Show All Devices. Then select the external device at the top level and click erase. This should allow you to choose MBR or GPT partition schemes.
