Hi again mighty Planet! Today I'm going to add yet another article on the series about Debian based Router/firewall systems (or how my weekends are truly weekends since I switched from GUI based routers back to plain old Linux/Debian routers where CISCO hardware is not an

The return of the Linux router... (from pfSense to Debian, part 4: from CARP to VRRP)

Hi again mighty World! So... lot of things going on, and little time to my blog, as more and more stuff piles up as article candidate. After some struggle, now I got my v6 CCNA Routing and Switching... CCNP starts after summer, and I'm very commited onto learning

Hey, hi again people... let's continue with the series of articles I have in mind, just as I have (just this week!) removed the last pfSense appliance at job and have it replaced with a Linux/Debian one. On this article I'm going to show a

The return of the Linux router... (from pfSense to Debian, part 1: The plan)

Hi again IT World... I've been quite busy lately... too much for comfort, and too often because of network issues (at the best). It has took me almost two months of work to regain our desired levels of stability and tranquilty, since we underwent the upgrade of our

PacketTracer 7.1.1 on Debian Buster

Hello again world! So... new year is here with plenty of activity... got finally a week of vacation to regroup and reorganize after my exams and having finally completed at job the core infrastructure migration. Got a lot of new experiences (and not always necessarilly good) with plenty of new

PROXMOX & OpenMediaVault 802.3ad against CISCO 3560g

Hi again people! This times of summer peace and tranquility are ideal to take the time to carefully rework parked labs and tests, and, one of the ones I wanted to solve once and for ever (since I live with similar production scenarios) is a one about setting up interface

Monitoring CISCO ACLs with ELK stack 5.4 (part4)

Hi again world! Summer is reaching its peak here at the Spanish coast... so less time to write IT articles and more time to outdoor fun ;-) Anyhow, let's end up this series of articles about setting up ELK stack and monitor CISCO ACLs. This one is the

Monitoring CISCO ACLs with ELK stack 5.4 (part3)

Hi again world! So, let's continue this series of articles about setting up a little, sigle server, all-in-one, ELK environment to draw nice dashboards about our CISCO labs. In this third article I'm going to dump my notes, and configuration for Logstash . I'll briefly

Monitoring CISCO ACLs with ELK stack 5.4 (part2)

Hi again people! In this second article (visit here part1 [/cisco-monitoring-with-elk-stack-5-4-part1/]) about ELK setup on Linux Debian to analyze CISCO logs (ACLs and/or PIX/ASA) I will keep giving shape to the notes I took during the actual setup. It is very useful to me to learn and consolidate

CISCO CSR1000 on ORACLE VirtualBox 5.1

Hi people! This article was in my sketchbook for several weeks right now. For me, finding that I could run XVR IOS CSR1000 virtual router over VirtualBox 5.1 has been a almots a milestone. To my taste, CISCO tends to be quite hostile when it comes to allow usage

Setting ejjaberd on Debian Jessie

Hi everybody! In the last few weeks I've been immersed in, paradoxically, Debian server setups, but not only at work, but also as part of some funny classes at Intitut Obert de Catalunya [https://ioc.xtec.cat] that deal about Internet Services. Among several typical examples and exercices,

RSA Key file based SSH on Debian Linux.

Hi again world! One of the best things I ever did since i first time played with an Amazon EC2 Debian instance, was to copy the SSH login procedure it came with to any other production system I take care of. Nothing, even changing listening port, has ever made more

Nice booting with non-free Debian Stretch NVIDIA drivers

Hi again people... So, this week I readed that, finally, NVIDIA proprietary linux drivers do enable DRM from kernel initial module load stages, and so, setting bootsplash animation during boot will no longer require legacy framebuffer tricky hacks... Unfortunately, driver version involved seems to be from 364.12, which is

I have long time owned this, very popular at its time, capture card, and it is still working fine in my Windows 7 based Media Center HTPC: It is able to tune DVB-T (terrestrial) digital and analog broadcasts nicelly and, in the same card, it is able to tune DVB-S

Getting rid of 'Zombie' processes.

I have read quite posts around looking for a way to kill processes marked as 'Zombie'... In theory (and I guess this assertion is true since it makes sense to me) zombie processes are harmless, since the process doesn't truly exist, it died or was killed

Debian Jessie, PC-Engines Alix, and the serial console.

Being close to my 40th year on Earth, and having had my first computer as I was 10 years old, I'm still very reluctant to drop some old school things such as RS-232 serial consoles to get system console. I love how easy and unchanged over time is

My tribute to kernel's IRQPOLL

This is something I should have done before, since to be sincere, and having put into production several encoding appliances very successfully thanks to this "kinda Linux Kernel hackish trick" I owe part of my IT career success to irqpoll kernel option... Yesterday, destiny faced me against my

Debian Jessie gateway fail-over switch daemon.

Hi again! Recently I resurrected an old Alix1d board that was thrown away in the office old-crap storage since I needed a cheap way to have an Internet gateway appliance that I could program to switch between uplinks. Although there are plenty of appliances to do so at first glance,

Conky monitoring widget Conky is a cool monitoring piece of software. When set with transparency, it provides a kind of cool, floating monitoring widget in your desktop, providing a clear, nice and quick overview of our computer, providing plenty of information from many sources (CPU clock, hardware temp, filesystem usages,
