MobaXterm and the Preferred Authentications.

Imagen
 Some months ago a co-worker suggested this application as it is very practical and saves you time if you need to setup a X server on Windows (like Xming), transfer files, etc. Everything was working fine until the last version that came available (I think it was probably version 21.1 or the next after that). when it started to request the password three times if you try to connect using ssh to a host running with Solaris. My first theory was that the ssh package was upgraded on all the hosts as OS upgrade was done but that was not happening with other applications like "putty.exe", so that was discarded. Then considered that by mistake I applied a change to the MobaXterm settings but nothing was different and even applying changes the original issue was present. After a lot of research one of the suggestions (sorry, lost the page and I hope to find it again to give the credits) worked for me, so here are the steps:   1.- Inside your "moba home" create ~/.bashrc (if...

Amigo organillero

Imagen
 Hoy por la tarde, un par de personas estaban recorriendo la zona con un organillo montador sobre un... ¿carrito?, no sabría que descripción darle. Lo importante es que nos alegraron la tarde con diversas canciones, para salir de la monotonía causada por la pandemia y ellos pudieron recolectar algo de dinero de los vecinos que salieron.

Unsigned application requesting unrestricted access to system.

Imagen
 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 ...

Hardware upgrade for Laptop Gateway M-6806m

Imagen
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...

AdGuard Home instead of pi-hole with a Raspberry Pi 2 Model B

Imagen
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. Executing: /lib/systemd/systemd-sysv-install disable pihole-FTL Now proce...

STAR WARS™ Special Edition Notebook and PCIe Bus error severity=Corrected

Imagen
A couple of years ago, wife needed a new laptop and bought a new notebook, the "STAR WARS™ Special Edition Notebook" specifically... because "star wars". You can see the model here: https://www8.hp.com/us/en/campaigns/HP_Star_Wars_laptop/overview.html She decided first to use the Windows  OS and later to have dual OS having Windows and GNU/Linux.  Some time later she went full with GNU/Linux distribution. November 11th - The notebook started to fail at boot, you can imagine that after this time the hard drive could have issues and that's what we confirmed. She'll buy a new hard drive... some time in the future. November 30, 2019 the future was that day and the 1TB hard drive was dead. When we had the new hard drive installed and ready, we tried with OpenSuSe but after the installation was done and first boot completed, it felt "slow" and we considered it was too much for this laptop and we decided to try with Mint. Agai...

Trying pi-hole to block ads, trackers and more.

Imagen
In the last months I've been using pi-hole to block ads/trackers/etc, here's a guide based on the official document and examples found on different sites/blogs. I'm using a Raspberry Pi 2 Model B along with raspbian  - Download/install/configure pi-hole # curl -sSL https://install.pi-hole.net | bash The installation script runs and you'll be shown the following: "This installer will transform your device into a network-wide ad blocker! " The next step requires you to provide the DNS upstream servers, consider using the Cloudfare DNS servers 1.1.1.1 and 1.0.0.1  or the DNS server you want. The installation is done and you should get the message: Installation Complete! The next steps depends on your home network configuration, on your router find the section where you set the DNS server and use the ip address that you configured for pi-hole. Now, open your favorite web browser and point it to the ip address assigned to the h...
