Quick and dirty robocopy script to back up directory

I used to have an xcopy script that ran this, but now I have upgraded to using robocopy to mirror my files to a network share that I disconnect and put in cold storage when not actually backing up.

robocopy E:\ \\192.168.50.30\backup\ /E /XD “System Volume Information” “$RECYCLE.BIN” “found.00*” /MIR

Break down of the script: E: is the SOURCE of my files and \\192.168.50.30\backup\ is my DESTINATION to copy TO. If you not the XD trigger, that EXCLUDES certain files. I want to ignore certain system files that do not matter to my back ups. You can do this for nearly any directory. /MIR is what actually MIRRORS the files, so they will look exactly like what you have on your SOURCE directory structure.

The only downside is there is no versioning with this, what you see is what you get, so if you were struck with some randomsware, this won’t save you. You would want something like seafile, or some other back up service. If there’s any interest, I can make a post on how to create a seafile server to do your back ups and version control. It has the added benefit of having versioning, browser accessible, and phone applications.

Windows Server 2019 Eval to Server Standard

I had issues converting an Eval server 2019 to a Standard Server 2019, and for whatever reason, it was painful to find the solution. Someone on reddit actually posted about it, so here is me documenting it for posterity!

Easiest way to install ESXi offline without any issues

I kept getting disk full issues when upgrading esx, this is such a silly error, and I really had no way around it outside of loading esx from a full iso and ilo in to boot. But I found a somewhat easier way to do it now via SSH and the upgrade update file.

  1. download the zip file from: https://my.vmware.com/group/vmware/patch#search
  2. upload it to a datastore
  3. Renamed it to update.zip – not required, but makes it easier
  4. esxcli software vib update -d /vmfs/volumes//update.zip
  5. reboot
  6. If complete, go ahead and delete the file if you want to reclaim the space.

How to add gold coins for eshop on Nintendo switch for physical games

I figured with Christmas coming, it might be a good time to add this. If you want to claim your eshop gold coins on physical games that you received, you can do so by going to the main Switch screen. Then highlight a game, press +, select My Nintendo Rewards Program, select Earn Points.

Easy! Enjoy. Remember they expire after 12 months of redemption.

idrac6 Unable to boot on Virtual iso file

I was playing around with an older idrac 6 server Dell R210 ii and discovered this when I was trying to run a memtest remotely. It was a simple fix, although I wish the error was a little more obvious. The fix is to go to:

In the idrac 6 interface; go to system > console/media, then click configuration and enable virtual media, and click auto attach. Once you do that, click Apply.

I circled the options in the following image with handy dandy SNIP, ha ha.

%ILET-1-AUTHENTICATION_FAIL on 2960X after IOS Update

I ran into this after updating a few 2960x’s with build dates of 2015. I attempted to down grade and had no luck with fixing. The research I did found 3 reasons the error popped up. Besides the error message popping up every 5 minutes or so, it killed all ip routing, making the switch useless. The exact error was:

%ILET-1-AUTHENTICATION_FAIL: This Switch may not have been manufactured by Cisco or with Cisco’s authorization.  This product may contain software that was copied in violation of Cisco’s license terms.  If your use of this product is the cause of a support issue, Cisco may deny operation of the product, support under your warranty or under a Cisco technical support program such as Smartnet.  Please contact Cisco’s Technical Assistance Center for more information.

The two fixes are to shut down the switch, and leave it unplugged for 10 minutes. The third requires an RMA. I ran into the third one sadly. I even tried the latest iOS as of August 25 2019. You can read more about the error here: https://www.cisco.com/c/en/us/support/docs/switches/catalyst-2960-x-series-switches/118837-technote-catalyst-00.html

How to import database through webmin

This took some digging, but here’s the method to import a database (.sql extension) into your webmin.

Webmin -> Servers -> MySQL Server

If the database already exists and you want to overwrite it with the contents of a .sql file (a mysqldump), click to select the database in the list.

Otherwise, click to create a new database. After creation, click to select that database.

The click “Execute SQL” and then “Run SQL from File”. Browse to find the .sql file and do it.

If you’re using Virtualmin the process is similar, except you start in:

Virtualmin -> (Choose Virtual Server) -> Edit Databases.

When you do it in Virtualmin the domain account is automatically granted access to new databases when you create them.

ssh to reset dell idrac ip address and other variables

I was working on something with an IP conflict, and then locked myself out of routing via the VPN, so the quickest way to do a fix, was to change the IP of my idrac via command line. Apparently, you can do almost everything through command line.

First step is to get onto your idrac, replacing root and IP with your own information. Note, default username and password is root – calvin. If you have a newer idrac, I think starting around idrac8, there is a tab on the server that has the default idrac username and password:

  • ssh root@192.168.0.120
  • racadm
  • racadm getniccfg

You should now have a print out of your current configuration for your NIC. To change it, you just do the following:

  • racadm config -g cfgLanNetworking -o cfgNicIpAddress  192.168.0.140
  • racadm set iDRAC.IPv4.Address  192.168.0.140

Give it a few seconds, and it should kick you out, and now have the new IP address.

If you want a full subset of the documentation go here: http://ftp.dell.com/Manuals/all-products/esuprt_electronics/esuprt_software/esuprt_remote_ent_sys_mgmt/integrated-dell-remote-access-cntrllr-7-v1.30.30_User%27s%20Guide_en-us.pdf

Otherwise here is a snippet:

% Get all iDRAC settings in a file

racadm get -f config.txt

If you like you can change the contents of config.txt and apply it back to iDRAC
racadm set -f config.txt

% Set password for root user
racadm set iDRAC.Users.2.Password PASSWORD"

% List all ssh keys for root user
racadm sshpkauth -i 2 -v -k all

% Add ssh key to root user
racadm sshpkauth -i 2 -k 1 "CONTENTS OF PUBLIC KEY"

% Delete ssh key for root user
racadm sshpkauth -i 2 -d -k 1

% Get iDRAC IP config

racadm getniccfg
racadm get iDRAC.NIC

% set iDRAC IP

Using config command:

Issues adding passwords on MySQL 10 or newer

I was trying to create a password for a new user on a new install of webmin. I was trying out the latest everything, latest MySQL (MariaDB 10), PHP 7.3, Kernel 5.0.2.12 running on Centos 7. But for some reason, when adding a new SQL user, I kept getting: failed :

Password hash should be a 41-digit hexadecimal number

What I had to do was enter the hash of the password into the new user script. To get the hash, all you have to do it go to command line, enter:

mysql -u root -h localhost -p

Then enter your passwords, and enter your password you want to kick back the hash on:

SELECT PASSWORD(‘mypass’);

Which will kick out:

6C8989366EAF75BB670AD8EA7A7FC1176A95CEF4

Poof, now you can enter that as your password via your gui, or as an SQL command:

Need a replacement for speed test by ookla?

I’ve been using fast.com, powered by Netflix and it’s been working great. I was getting annoyed with ooklas somewhat intrusive ad tactics and was looking for something a little better. Fast.com works great and has a great little application door Android as well.
