  • Linux gateway/router + unable to access certain (HTTPS) sites

    I’ve had an issue for a while, being unable to access certain websites such as https://fon.com, but also certain parts of the Apple, Fortis and Microsoft site, while other (https) websites worked fine. Running Wireshark I found that only about 5ish packets got transferred, and all other data to that website abruptly stopped. I’m using…

  • Public DNS server

    I have been running a public DNS server for private purpose (never liked my ISP’s DNS servers, and the root servers were usually located too far away (at least those with easy to remember IPs).

  • Prowl: check server status (using ping)

    Yesterday I’ve start using Prowl, as I heard good comments about it. And one of the things I want it to check, are my server statuses. I made a quick script using bash and crontab to check every 10 min if it replies on ping. Per server, I created “host.domain.tld.sh” (e.g. zero.rootspirit.com.sh), and added this…

  • Vodafone Mobile Connect – Incorrect Pin code

    As I usually use my SIM card in my iPhone, I booted my PC, plugged in the Vodafone USB Mobile Connect modem (HAUWEI 220 or something). I then inserted, with the USB device plugged in, my SIM card, and booted up the Mac (and later on Windows) Vodafone application, to connect my PC to the…
