I’ve recently changed my ssl certificates to fix some problems regarding subdomain handling. As firefox and other browsers complained:

You have attempted to establish a connection with “blogs.nopcode.org”. However the security certificate presented belongs to “nopcode.org” (…)

My SSL certificates are not self-signed, I use a CA known as CAcert instead. This is one of their a logos:

I’ve joined that CA six months ago and I’m really happy with it. I’ve learnt lots of issues about SSL, certificate generation, CA’s, security devices, trust policies, server configurations, code signing, etc…

If you want to know more about certificates, check cacert’s wiki, there’s a lot of interesting stuff there, including how to join CAcert’s WoT

As pool.ntp.org website states:

The pool.ntp.org project is a big virtual cluster of timeservers striving to provide reliable easy to use NTP service for millions of clients without putting a strain on the big popular timeservers

I’m using this service for ages, and one day I though that it was fair to contribute a really minimal amount of bandwidth to help improving the overall reliability of pool.ntp.org… well at least pool.europe.ntp.org

I’ve measured the instant and average bitrate in KB with mesure, these are the results:

# time ./mesure -i eth0 -K -p "udp and port 123"
49

real    0m59.546s
# time ./mesure -i eth0 -K -a -p "udp and port 123"
0

real    4m52.314s

Després de més d’un mes de mails i faxos enviats a “Gestión de dominios de Auna TLC”, per fí he aconseguit que el meu actual ISP, canvii el registre PTR dels seus servidors DNS.

Per a que volia aquest canvi ? Doncs bàsicament per esborrar el meu servidor de les llistes negres d’spam (per el simple fet de ser un usuari d’un ISP amb una pool d’IP’s dinàmiques).

En el moment d’escriure aquestes línees, dnsstuff indica que el meu servidor està llistat a tres bases de dades d’spam. La que més em preocupa és SORBS-DUHL, ja que alguns servidors de correu coneguts usen aquesta llista per refusar mails entrants (per exemple vodafone.es).

Sembla que a diariolinux se m’han avançat mentre tenia aquest post a mitjes, tot i així tinc ganes d’explicar la meva experiència, així que posem-nos mans a la obra

Primers passos

Ja sigui per motius de feina, donar-se de baixa d’algun servei de telefonia, tràmit burrocràtic, etc… tots hem passat pel tràngol que suposa enviar un fax, sobretot quan no en tens cap a l’abast i et corre pressa.

És el moment doncs, de rescatar el nostre mòdem, (en el meu cas es tracta d’un USRobotics Sporster 33.6 extern), connectar-lo al server i fer un:

So here it is: yet another personal geekish blog You may be asking… why another one ? Well, I’ve some thoughts, projects, wishes… interests for short, which I’m really willing to share for too much time till now.

My main purposes on this blog are manifold: technical writings, thoughts, findings, reflections… and of course being interesting and fun altogether. Moreover, I hope you would enjoy it like I will ! Please, feel free to post comments !

In addition, I decided that posts will be indifferently written in English, Catalan or even Spanish because I don’t want to stuck on my way of expressing in just one language and because I enjoy using them all.

Last but not least I want to thank the people who helped/advised me and I learnt from while deciding to start my blog: pof, jmmv, pancake & 3des.
