    • RE: Hyper V Tape passthrough possible?

      Veeam says:
      https://www.veeam.com/blog/tape-backup-best-practice-from-support-team.html

      You will need a tape server that will perform most data transfer tasks during archiving to tape. Check the following prerequisites:

      • This should be a physical machine or a VM connected through iSCSI, since direct pass-through is not supported.

      To run it as a VM you have to be able to use iSCSI to your tape. Since that doesn't work in this case there is only the physical option left.

    • RE: PoE issues with Unifi switch

      Anyway, find the actual problem by disconnecting everything and connect things one by one.

      Real PoE for instance negotiate power the the device on the other end. I think PoE supports a crossover ethernet cable just like any switch or NIC can. But passive PoE? It'll probably short-circuit something.

      If a cable is crossed somewhere like TIA-A or B wiring in the wrong place you might have a situation like that.

      PS. You might want to get a cat6 cable tester so you can verify the wiring. A simple one would get the job done.

    • RE: how does this work? Modems/IPs/PCI Scans

      @WrCombs said in how does this work? Modems/IPs/PCI Scans:

      @Pete-S said in how does this work? Modems/IPs/PCI Scans:

      When you say "modem" what do you mean exactly? What is it connected to?

      This question confuses me.
      A modem is a modem, right? connects to the Cable and becomes internet through FM

      A modem is a modulator/demodulator. But there are many types of modems and some modems are not modems at all. People who don't know better just call them that. That's why I asked.

    • Windows Server licensing for HA?

      If you have two servers and run HA, does that mean that you have to license Windows Server standard for the maximum number of VMs running when you have a failure?

      So for example,
      Server A: 16 cores, runs 6 VMs normally
      Server B: 16 cores, runs 6 VMs normally

      So each server has to be licensed for all 12 VMs running on 16 cores - so 6 x Windows Server Standard licenses for each server, total of 12 licenses?

      But if you didn't run HA, you would only license each server for 6 VMs, with 3 x Windows Server Standard, a total of 6 licenses?

      Is this correct?

    • RE: How M$ shakedown stupid corporations

      To get accurate time sync on windows you install ntp. It's as simple as that.

      The W32time service in Windows is to ntp, what timesyncd in linux is to ntp - a simple and not-accurate but often good enough time sync for clients.

      BTW, already back in the Windows 3.1 days you had something called Tardis that you would run for NTP sync. Windows own time service was only designed to keep time reasonably synced for kerberos and stuff like that. I think it appears first in Windows 2000 Server.

    • RE: 3CX Linux Beta

      @Dashrender said in 3CX Linux Beta:

      my question would be - why risk something that you might have to spend money on when there are definitely options you don't have to spend money on that should get the job done?

      Time is money so you're spending money either way. So it a question of TCO and what features you need.

      3CX is a polished product. Well integrated with Yealink for instance. So when you push a button and have all your phones upgraded to the latest 3CX/Yealink firmware you pretty much know that everything is going to work afterwards. You don't have to be the beta tester.

      I would imagine a professional tinkerer like @JaredBusch would never be satisfied with something like 3CX though. Being an MSP also put you in a different position compared to being the end user.

    • RE: Tar gzip file compression calculation without decompressing the file

      @DustinB3403 said in Tar gzip file compression calculation without decompressing the file:

      @Pete-S So the simplest way I can think to explain this would be like this.

      You have a network share which is relatively organized

      You create a compressed tarball of any folder on that share and then move that tarball to offsite storage.

      How would I realistically get a hash of that folder pre and post tar and compression and have it make sense? They aren't the same thing, even if they contain the same things.

      @Pete-S said in Tar gzip file compression calculation without decompressing the file:

      Is it safe to assume that the gzip file is correct when it is created?

      This is what I'm looking to verify 🙂

      I'm assuming that files are static during backup.

      If you first of all run md5deep on all files in the folder, you'll create a textfile that contains md5 (or sha256 or what you want) signatures on every file in the folder. Place it into the folder so it ends up inside the backup and you'll always have the ability to verify any uncompressed individual file.

      If you really want to verify your tar.gz file after it's created I think you have to decompress the files to a temporary folder, run md5deep on the files to compare them with the original file. What you really are testing is that the backup-compress-decompress-restore operation is lossless on every file. It should be by design, but if there is an unlikely bug somewhere it's technically possible that it might not be.

      If you use the gzip compression with tar, gzip has a CRC-32 checksum inside that can be used to verify the integrity of the gzip file.

      Or to be even more certain you can create an md5 signature of the entire gzip archive with md5sum or md5deep. Then you can always verify that the archive has not been corrupted.

      If you ever need to restore the files you can verify the integrity of the restored files with the md5 you created on the original files, before you did the backup.

    • RE: nohup

      Good reminder @Emad-R !

      I use screen a lot.

      Allows multiple sessions inside one ssh session. And allows you to reconnect to those sessions at a later time. So it can also be used for stuff that takes a long time to complete.

      Usage:

      screen
      

      then do what you want to do, if it takes to long and you cancel the ssh or the ssh session is aborted, then reconnect next time you login with:

      screen -x
      

      Shortcuts:

      • Start another session while working: Ctrl-A + c
      • Switch to first session: Ctrl-A + 0
      • Switch to second session: Ctrl-A + 1
      • Switch to third session: Ctrl-A + 2
      • etc etc

    • What setting for DNS when there is no DNS server?

      In linux, what should you set the DNS settings to when there is no DNS service that can be accessed? By design, not as a mistake (just to clarify).

      So if you for instanced tried to access a DNS server it shouldn't even try and then timeout. It should just immediately return "host not found".

    • RE: Delays on servers from Dell

      @scottalanmiller said in Delays on servers from Dell:

      @syko24 said in Delays on servers from Dell:

      I talked to my rep today and he confirmed the CPU was the item holding everything up. I asked if there was a different CPU option that would speed things up. He said regardless it would be a minimum 10 days before it would ship. I cancelled and ordered a refurb.

      I wonder why Dell is so committed to only using Intel when there are major supply chain issues? AMD has some great options and I've not seen delays from AMD parts.

      Dell have plenty of AMD servers too. R7515, R6515 are their new 1 CPU EPYC Rome (2nd gen) models and R7525, R6525 their two CPU models. Then they have some other model in the C-range. And their older 1st gen EPYC servers.

      With the prices and performance of AMD EPYCs you have to have a really good reason not to go AMD at this point.

      @Obsolesce said in Can all phones read QR codes natively?:

      I was looking over my wifi settings here....

      No need for that site!

      That's great!

      For us that don't have that in the AP.

      From the link above it looks like the format of the text in the QR code is:
      WIFI:S:<SSID>;T:<WPA|WEP|>;P:<password>;;

      That means you can use duckduckgo as well to generate the QR code, or any other tool or site or label printer that can do QR.

      For instance with SSID=GUEST_WIFI and password=AGZ53k!-12a the QR code should be:
      WIFI:S:GUEST_WIFI;T:WPA;P:AGZ53k!-12a;;

      So using duckduckgo it becomes: qr WIFI:S:GUEST_WIFI;T:WPA;P:AGZ53k!-12a;;

      Result is:
      wifi.gif

      The QR works fine on my Android phone.

    • RE: Network setup - moving forward

      @Dashrender said in Network setup - moving forward:

      Example, one thing we have tons of is Excel sheets people fill out daily - If we had a web form to fill out instead, we could likely get rid of Excel. of course on the back end (for management who wants reports) we'd need the ability to create reports from that data. that could be done with Excel, or the report could be created in the web package. But these are things I've never done before, have no clue how to do, or really where to start. I'm guessing with some sort of PHP script and a DB on the back end is the starting point.

      Easiest way (and cheapest) to make that happen is to find a developer who can do it for you.

      A web interface allows the user to feed the back-end SQL database. With the data structured you have many options to use that data in meaningful ways - through a webserver or in many other ways.

      PS. In my experience most companies need more than just generic forms and more than just generic reports. Usually it's about automating or support a process in the business.

      @DustinB3403 said in LibreOffice - Runs so slowly:

      Has anyone else noticed that LibreOffice, Calc and Impress in particular run so slow? Anyone have any pointers on how to improve the performance.

      Windows and OSX

      Slower than MS Office? In what way?

      In the I have a 437MB file and the transitions aren't smooth. It might be my system (I do have a lot open atm) but it just seems impractical

      Open/LibreOffice is java based. Has always been slower. I don't know why it soo much slower when you have huge documents either.

      But the pro tip for running presentations is to convert them from powerpoint to pdf and run them in full screen mode. Your 437MB file will probably end up a 10MB file or something like that.

    • RE: Comparing Office Suites

      Isn't stretching it extremely far to put Zoho among the major players?

      Mayor players has to be Microsoft & Google. Then way down, common open source suites like libreoffice/openoffice. And then the rest, including Zoho.

      Even compared to online suits only, Zoho can't have more than a few percent of the market if even that.

    • RE: Getting started with automated provisioning?

      @biggen said in Getting started with automated provisioning?:

      I’m not sure the difference between a clone and a copy. I’ll look that up.

      It's just how the storage is handled.

      Say that you have a debian install that uses 10GB. If you make a clone, the clone will also use the same 10GB of storage and only whatever blocks that it changes are stored separately. So if you make 9 clones maybe the entire 10 VMs will use a total of 11GB or something.

      If you make a copy, the storage from the original VM is copied into a new but mostly identical 10GB. And the second another 10GB and so on. With a total of 10 VMs the total storage used are 100GB.

      Clones are more frugal on storage but has more overhead so might be a little slower.
      Clones use the same storage mechanism as snapshots while copied VMs are just a copy.

      Practically speaking it's faster to work with clones but if you're cloning small VMs like minimal installs and have SSD disks the difference in time is small.

    • RE: Re-evaluating Local Administrative User Rights

      If you think about it, letting the users run as admins shouldn't be a problem. Not if you have designed your network with zero trust in mind - assume every computer sits directly on the internet, assume everything is compromised.

      So the only thing they should be able to screw up is their own computer - in which case you should be able to bring it back quickly with automation.

      That said, I think developers need their own server(s). A test environment where they can create and destroy VMs and run containers and whatever else they need. Do development and run performance tests. Let them run wild in there. It could be cloud or on-prem or whetever it is they are developing.

    • RE: Covetrus AviMark Cannot Locate Microsoft Word Installation

      @scottalanmiller said in Covetrus AviMark Cannot Location Microsoft Word Installation:

      It's ghost ship software from the 1990s.

      Doesn't really matter if you want it to work.

      Pascal, that should be Delphi then. Doesn't matter either in this case because COM api has nothing to do with .NET. But Delphi produces real compiled exe files like C++ so it has full access to all windows APIs.

      Unfortunately I've forgotten most things about COM objects, OLE automation and ActiveX.

      What I do remember is that you go by the CLSid to invoke the COM object. Since the error is that it can't find the application it's either the wrong CLSid (registry related) or the wrong permissions/security settings.

      When you troubleshoot COM automation you usually run the automated application with desktop interaction so you can see what happens. Not an option here though but it doesn't really matter because you don't get that far.

      That's why you need to write a small program that invokes Word because if you can't, then your installation is the problem, not the AviMark application.

      But you haven't provided much info in this thread (screenshots, versions, registry settings etc) so I guess you're not really trying to solve the problem, you just want to bitch about it.

    • RE: Making a Raspberry Pi 4 or Similar SBC Desktop

      Problem with RPI4 is that when you want it to be as fast as possible, you are getting close to the Intel price range. So as an option it works best if you stick to a basic config.

      And to get a useable desktop you also need a monitor, a keyboard and a mouse. Say $150 if you have modest needs.

      So

      • Desktop with RPI4 (4GB RAM & 32GB microSD) $250
      • Desktop with NUC J3455 or similar (8GB RAM & 120GB SSD) $325

      The desktop with the Intel CPU has probably double the performance for 30% higher overall price. So value for money is better - if you need the extra performance.

      NUC are also SBCs and the Odroid H2 mentioned above is the same (Intel J4105).

      Intel CPUs to look for that are low-end but still significantly faster - J3455 (older model), J4105 and J5005. These are 10W Celerons with 4 cores in the 1.5 to 2.5GHz range.

      Obviously something like an i3 is much faster but it will bump up the price another notch.
