Anecdote of a networking class (Marcos Samuel)

 Hello, I'm going to tell you a curious thing that happened to me during my first year at Puenteuropa, a professional training center. It was a very fun day for me because we were going to have a class on networks and we were going to climb up some ethernet cables for the first time.


Being the clumsy person that I am, I plugged in the RJ45 cable in both ends. When it came time to insert it into the NIC interface on the computer and seeing that there was no network, I thought I had made a mistake with the color order and immediately tried to remove the cable from the NIC.

RJ45

NIC interface

I saw that it wouldn't come out and it was very hard to pull on it, so to avoid making a bigger mess, I called Juan Carlos and he saw that the RJ45 connected to the NIC was stuck for some reason, and then he called Roberto and he saw that the RJ45 I had previously climbed up was defective from the factory, I think the cause was that the pins on the RJ45 were one on top of the other or something like that.


In conclusion, I broke a network card or that's what I think. Since that day, I pay close attention to what I buy so that it doesn't have any defects. And finally, I felt a little bad for breaking that. (I don't know if Roberto was able to fix the network card, let's hope so).

labs we did with juanma

Yesterday Juanma put a labs about connecting switches and routers between them to give wifi to our pcs but we had a problem with the switches and routers because it didn't work. for our luck Juanma helps us after a long time with a lot of errors in the switches and routers, but we had another problem that we didn't have the infratestructure that juanma said to have and when he asked us to do a wireshark to search the apache it didn't show in the wireshark because we didn't mount it in the debian we only had the dhcp. the other day we had another problem with the same thing (not the infrastructure but the switches and routers) and I hope that the next time he will say to do the labs again we will do it perfect.

Today's class (Raúl García)

 I started my day with AWS class, we had to make diferent virtual machines on amazon web services, so we could put a web page, on which you had to register to see it. I wasn't sure about how to make the "EC2 instances" so I had to watch a YouTube video, I didn't had enought time, but next week we will have more time. Next we had english class, we started with an exam, for me it was easy, so I didn't had any problem there. After that the teacher presented the new project we had to do, on which que have to make a job interview with a teammate in two weeks. I will make the project with Samuel, he is one of my best friends here in puenteuropa, we will do great for sure!

vpn explanation

  A VPN, or Virtual Private Network, is a technology that allows users to securely connect to the Internet over an untrusted network, such as a public Wi-Fi network. When a user connects to a VPN, the VPN server creates a secure, encrypted tunnel between the user's device and the VPN server. All data transmitted between the user's device and the VPN server is encrypted and protected from unauthorized access or interception. This allows users to securely access sensitive information, such as financial transactions or confidential business data, even when using a public Wi-Fi network or other unsecured network. VPNs are also useful for users who want to access content that is restricted by geographic location, such as streaming services or websites that are only available in certain countries. VPNs are typically used by individuals, businesses, and government organizations to protect their online privacy and security. There are many different types of VPNs, including remote-acces...
