Winbox configuration files

Posted by jpluimers on 2021/12/31

A few notes:

WinBox configuration files are under %APPDATA%\Mikrotik\Winbox
- The subdirectory sessions contains binary *.viw files that seem to represent “view” configurations (the positions, dimensions and other properties of the open Windows in a Winbox session) where the * of the name seems to be an IPv4 address of a machine.
- Directories named like 6.40.3-2932358209 and 6.43.13-695307561 contain configuration files that seem to determine what WinBox features a certain RouterOS version should reveal; files in those directories seem to always be these:
  - advtool.crc / advtool.jg
  - dhcp.crc / dhcp.jg
  - hotspot.crc / hotspot.jg
  - icons.crc / icons.png
  - mpls.crc / mpls.jg
  - ppp.crc / ppp.jg
  - roteros.crc / roteros.jg
  - roting4.crc / roting4.jg
  - secure.crc / secure.jg
  - wlan6.crc / wlan6.jg
- There are binary files Addresses.cdb and settings.cfg.viw
- A text file named sessionpath contains the expanded path %APPDATA%\Mikrotik\Winbox\sessions

The *.crc files contain a CRC code, presumably on the contents of the correspoding *.jg file. The *.jg files seem to contain some kind of JSON.

Leerlingen zelf een toets laten maken die ze zelf kunnen nakijken (door Martijn Leisink)

Posted by jpluimers on 2021/12/30

[Archive.is] Martijn Leisink on Twitter: “Soms wil je leerlingen een zelftoets laten maken. Je wil dat ze die zelf na kunnen kijken, maar tegelijkertijd wil je juist niet dat ze meteen de antwoorden op kunnen zoeken. Dat lijkt tegenstrijdig, maar er is een manier! (Ter inspiratie voor andere bèta-docenten.)… “

Thread: [Wayback] Thread by @mleisink on Thread Reader App – Thread Reader App

Truc: [Archive.is] Harry de Jonge on Twitter: “In eerste instantie 8 van de 9 goed. Uit de formule volgt dat ‘t te behalen totaal aantal punten n x 360 – 90 moet zijn, met behulp daarvan bepaald dat ik vraag 8 fout had. Ergens 2 of 4 van aftrekken is nog lastig😀 Natuurkunde is toegepaste wiskunde.… “

Zelf maken: [Archive.is] http://zelftoets.wiskunstelaar.nl/

Maak een aantal vragen met telkens drie antwoordopties.
Zet de getallen in de tabel hierboven voor de antwoorden.
Een leerling kan met het volgende recept controleren hoeveel antwoorden hij goed heeft:

Tel de getallen voor het antwoord van jouw keus bij elkaar op.

Vermenigvuldig het resultaat met 10.

Druk op de knop sinus en vervolgens op de inverse cosinus.

Deel de uitkomst door 20 en je weet hoeveel vragen je goed hebt beantwoord.

Leerlingen kunnen dus wel achterhalen hoeveel antwoorden ze goed hebben, maar niet welke antwoorden goed zijn.
Let er overigens op dat de rekenmachine op graden moet staan en niet op radialen!

windows 7 – How can I eject a CD via the cmd? – Super User

Posted by jpluimers on 2021/12/30

Quite a while ago I found [Wayback] windows 7 – How can I eject a CD via the cmd? – Super User, but forgot to document that in the batch-files I created from it.

It shows both this one-liner:

powershell "(new-object -COM Shell.Application).NameSpace(17).ParseName('D:').InvokeVerb('Eject')"

The hardcoded const 17 is for the ssfDRIVES element in the ShellSpecialFolderConstants, which is documented at [Wayback] ShellSpecialFolderConstants (shldisp.h) – Win32 apps | Microsoft Docs.

There is no PowerShell equivalent of that element, hence the hardcoded value 17.

The script invokes the verb Eject, which works on any kind of removable media (not just optical drives). If you want to limit it to only certain drive types, then you would need to compare the Type of the ParseName() result. However, that result has a Type property returns a string for which the possible values are not documented.

Here are some links I tried to find out what is returned:

[Wayback] Shell.NameSpace method (Shldisp.h) – Win32 apps | Microsoft Docs (returned by (new-object -COM Shell.Application))
[Wayback] Folder object (Shldisp.h) – Win32 apps | Microsoft Docs (returned by NameSpace(17))
[Wayback] Folder.ParseName method (Shldisp.h) – Win32 apps | Microsoft Docs (returns a list of FolderItem structures)
[Wayback] FolderItem object (Shldisp.h) – Win32 apps | Microsoft Docs (returned by ParseName('D:'))
[Wayback] FolderItem.InvokeVerb method (Shldisp.h) – Win32 apps | Microsoft Docs (executes the Verb on the FolterItem)
[Wayback] FolderItem.Verbs method (Shldisp.h) – Win32 apps | Microsoft Docs (lists the verbs the FolderItem supports to be executed via InvokeVerb)
[Wayback] FolderItem.Type property (Shldisp.h) – Win32 apps | Microsoft Docs (string indicating the type, which for a FolderItem representing a drive will be the drive type)

In addition to the Shell.Application, there also is Scripting.FileSystemObject, which allows enumerating the drives and filter on DriveType. This is the relevant documentation:

[Wayback] FileSystemObject Object | Microsoft Docs
[Wayback] Drives Property | Microsoft Docs which returns a Drives collection type where each item is a Drive type.
[Wayback] Drives Collection | Microsoft Docs collection of Drive type elements
[Wayback] Drive Object | Microsoft Docs a single element of the Drives collection

[Wayback] DriveType Property | Microsoft Docs property of the Drive type indicating the type of drive:

Case 0: t = "Unknown"
Case 1: t = "Removable"
Case 2: t = "Fixed"
Case 3: t = "Network"
Case 4: t = "CD-ROM"
Case 5: t = "RAM Disk"

The second example in the above mentioned answer shows how to use this to filter for optical drives.

It also shows a cool technique to have a hybrid batch-file/JScript script:

@if (@CodeSection == @Batch) @then

@echo off
setlocal

cscript /nologo /e:JScript "%~f0"

goto :EOF

@end // end batch / begin JScript hybrid chimera

// DriveType=4 means CD drive for a WScript FSO object.
// See http://msdn.microsoft.com/en-us/library/ys4ctaz0%28v=vs.84%29.aspx

// NameSpace(17) = ssfDRIVES, or My Computer.
// See http://msdn.microsoft.com/en-us/library/windows/desktop/bb774096%28v=vs.85%29.aspx

var oSH = new ActiveXObject('Shell.Application'),
    FSO = new ActiveXObject('Scripting.FileSystemObject'),
    CDdriveType = 4,
    ssfDRIVES = 17,
    drives = new Enumerator(FSO.Drives);

while (!drives.atEnd()) {
    var x = drives.item();
    if (x.DriveType == CDdriveType) {
        oSH.NameSpace(ssfDRIVES).ParseName(x.DriveLetter + ':').InvokeVerb('Eject');
        while (x.IsReady)
            WSH.Sleep(50);
    }
    drives.moveNext();
}

Some notes on ESXi `smartinfo` throwing `error Cannot open device`

Posted by jpluimers on 2021/12/29

I wrote about the built-in smartinfo command before at NVMe and SATA health data on ESXi: some links to investigate.

It is at /usr/lib/vmware/vm-support/bin/smartinfo, which is not in the path. I used it recently after having trouble with some 2.5-inch SSD devices, of one which is listed below.

Some note on this error what smartinfo from ESXi throwed on some devices over time on various ESXi machines:

Failed to get SMART stats for t10.ATA_____Samsung_SSD_860_EVO_500GB_______________S3Z2NB0M529545P_____ error Cannot open device 
-----------------------------------------------------

The same SSD sometimes had very big latency times:

[Wayback] “smartinfo” “error Cannot open device” – Google Search delivered mainly results around the old smartinfo.sh tool that is now replaced by the smartinfo binary:

[Wayback] “ESXi” “smart” “error Cannot open device” – Google Search returned no relevant results.

I think an 860 EVO 2.5-inch SSD is not on par running half a dozen Windows VM’s that have regular write actions, but I will later give this a try, though I doubt it will help as this is on a VMware 6.7 update 3 based system which should not have the vmw_ahci driver slowness:

[Wayback] NVMe SSD Fast, but SATA SSD slow ! – VMware Technology Network VMTN (hyphen fixes mine):

I have done the esxcli system module set --enabled=false --module=vmw_ahci and rebooted, and I got a small performance increase. But still not what I thought.

It refers these other posts:

[Wayback] HomeLab – SuperMicro 5028D-TNT4 Storage Driver Performance Issues and Fix – VIRTUALIZATION IS LIFE!
[Wayback] Easy fix for Supermicro and other Xeon D systems experiencing SATA3/AHCI slowdown on ESXi 6.5 | TinkerTry IT @ Home
[Wayback] AHCI (vmw_ahci) performance issue resolved in ESXi 6.5 Update 1 (hyphen fixes mine):
With the release of ESXi 6.5 Update 1, I am happy to report the observed performance issues with the Native AHCI driver have now been resolved! I have been running on earlier release of ESXi 6.5 Update 1 build for couple of weeks now and have not seen any of the problems I had before. For those interested, the official fix went is in version 1.0.0-37vmw or greater of the vmw_ahci driver.

…

If the Native AHCI driver is disabled as shown in the previous command, then you can re-enable it by running the following ESXCLI command:
```
esxcli system module set --enabled=true --module=vmw_ahci
```

The system with this behaviour is on these versions:

# esxcli software vib list | grep ahci
sata-ahci                      3.0-26vmw.670.0.0.8169922             VMW     VMwareCertified   2021-04-03

media.ccc.de – No, we won’t have a video call for that! (Communications in distributed teams by Florian Haas)

Posted by jpluimers on 2021/12/29

Not just for during the Covid times: the helpful examples and thorough explanation by Florian makes this a must-watch video for anyone wanting to participate in distributed teams.

[Wayback] media.ccc.de – No, we won’t have a video call for that!

The above link has downloads for both Video (mp4 and WebM formats) and audio (mp3 and opus formats). I found the video easier to digest.

If you want to watch it on-line, there is the YouTube video (below the signature) which has closed captions as well.

Kristian Köhntopp made a [Wayback/Archive.is] short intro and abstract on Twitter:

https://xahteiwi.eu/resources/presentations/no-we-wont-have-a-video-call-for-that/

Exactly one year ago, the office building I was working from every work day caught fire, and was closed for a month for renovation.

On the day of the planned reopening, my employer declared Covid emergency and asked everybody to work from home.

So that is how we work since then, and we will continue to do so until at least October.

Not too much has changed, though. When the new https://oosterdokseiland.nl/en/ opens, there will be probably a lot of pain between the people who go to the office to work and those who don’t.

The talk above by @xahteiwi explains in a nice way how to work properly remote first:

Writing over speaking.

Asynchronous over synchronous.

Structured communication over free form.

Some things require a free form video chat, but even then, set an agenda and write minutes.

Florian also explains when to use what, and what situations would require a synchronous wide-band channel, but most of them are exceptional, and most of the time you could execute better using structured, written, async mode comms.

Having said that, if you want his talk as a briefing, here is a Youtube: https://www.youtube.com/watch?v=NVnci3tyDa4

First watch the video, then read the full speaker notes at [Wayback] No, We Won’t Have a Video Call for That! – xahteiwi.eu “My talk from FrOSCon 2020, Cloud Edition.”

Chrome: allow some URLs to “never sleep” (or hibernate/discard)

Posted by jpluimers on 2021/12/29

This option in Chrome has moved around a bit, so here is how it was in Version 89.0.4389.90 (Official Build) (64-bit) when I documented it.

Browse to chrome://discards/
Don’t be intimidated by the many rows and columns; only the rightmost 8 (at the time of writing) are interesting:
Search for the URL (in my chase https://web.whatsapp.com/ , so I searched for whatsapp which you see as orange in the screenshots below) for which you want to ensure it will never sleep/hibernate (Chrome calls this “discardable”)
Click Toggle under the checkmark ✔ so it changes into a cross ✘️ (so the URL will never be discarded, hence always stays awake)

Do this only for tabs that are not CPU/memory/traffic intensive

I got there via these posts:

[Wayback] How to Prevent Chrome from Reloading Tabs When You Switch to Them (which mentions the old style solution browsing to chrome://flags that does not work for this problem any more)
[Wayback] Stop Chrome Tab Sleeping/Hibernating – Stack Overflow which corrects the expired answer by providing a correct chrome://discards alternative.

When searching for discards, I found this post: [Wayback] How to Prevent Chrome from Reloading Tabs When You Switch to Them

Chrome has built-in memory management that causes inactive tabs to “sleep” as RAM is filled. When you click the tab again, it has to reload the page. It’s annoying.
