If you are a System Administrator, you probably use MobaXterm as your go-to tool for its versatility: integrated X server, SSH client, SFTP file transfer, and more. However, since version 21.1, many users started experiencing a frustrating issue: MobaXterm requests the password three times before allowing access to certain hosts, particularly those running Solaris . In this article, I’ll explain why this happens and how to fix it permanently by adjusting your SSH configuration. The Problem: Why does MobaXterm ask for the password repeatedly? At first, you might think the SSH package was upgraded on the server side or that a system-wide OS upgrade changed the security policies. However, if you test the connection with other clients like Putty.exe , the issue does not occur. The root cause lies in the Preferred Authentications order. MobaXterm tries several methods that the server might not accept immediately, exhausting the allowed attempts before falling back to the interactive keyb...

 This week I had to work with an appliance and had to launch a remote console via ilom but everytime I tried the following window was displayed: So, I did a search for "The following resource is signed with a weak signature algorithm MD5 with RSA and is treated as unsigned" and found three links https://www.blackmoreops.com/2017/06/08/fix-java-error-unsigned-application-requesting-unrestricted-access-to-system/ https://learningintheopen.org/2017/11/03/java-jnlp-error-weak-signature-algorithm-md5withrsa/ and https://www.cyberciti.biz/datacenter/bmc-ipmi-kvm-java-applets-broken-with-java-security-update/ basically one has to comment out a line containing the words "jdk.jar.disabledAlgorithms" to the file on a similar path on my system (I'm using Win10 and the latest java version available) C:\Program Files (x86)\Java\jre1.8.0_261\lib\security\java.security The line I found is: jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024, DSA keySize < 1024 After ...

So, after some weeks learning about the Oracle Certification "Oracle Cloud Infrastructure - Foundations Associate"  I'm officially certified! Let's see what else I'm going to learn later. :)

It was time to make the PC a little more fun and decided to buy a couple of led fans, the brand is "Eagle Warrior" which is a Mexican brand of gamer products.   You can reach them via:  www.eaglewarrior.net / https://twitter.com/eaglewarriormx?lang=en   These is the look of the brand: And how the PC looks now: So far so good, both working and look great!

I'm doing a hardware upgrade to this  old   laptop by upgrading the RAM from 2G to 4G, removing the DVD and adding a caddy to store the original hard drive were the DVD was and a new SDD to install the OS instead of the original HDD. The caddy I gouth is a PATA IDE to SATA, 12.7mm to connect the original HDD, which you can see over the DVD and the SSD already connected and protected by that metal "cage" to the left. Now, you can see the original RAM installed and the new 4G protected with the envelops they were sent by the provider: And now, these are the brand new 4G RAM installed:  Now, this is how it looks the caddy taking the place and simulating being the DVD (at the bottom): The old BIOS detects the new RAM installed: But I had a problem with the BIOS to put the SSD as the primary boot device and the HDD as secondary,  somehow the HDD went to the "bottom" of the options and it was complicate to put it below the SSD. When I finally got the drives in the boo...

In the last days/weeks I'm seeing people talking about "AdGuard" instead of "pi-hole" so I decided to give it a try. These are the steps I followed to install it using the Raspberry Pi 2 Model B where I have pi-hole running at the moment. First, stop/disable pi-hole: pi@localhost:~ $ pihole disable   [i] Disabling blocking   [✓] Reloading DNS service   [✓] Pi-hole Disabled pi@localhost:~ $ sudo systemctl stop lighttpd pi@localhost:~ $ sudo systemctl disable lighttpd Synchronizing state of lighttpd.service with SysV service script with /lib/systemd/systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install disable lighttpd pi@localhost:~ $ sudo pihole disable   [i] Blocking already disabled, nothing to do pi@localhost:~ $ sudo systemctl stop pihole-FTL pi@localhost:~ $ sudo systemctl disable pihole-FTL pihole-FTL.service is not a native service, redirecting to systemd-sysv-install.
