  • shopping in the darkness of the early Caribbean evening

    I really like the local Carrefour / Dillon. Their own articles are apparently targeted towards the Francophone + Dutch market, so the articles are labeled in the resp. languages. I only saw this  a lot, when I lived and worked in Antwerp, but I did not expect to see this again out here in the Caribbean.

    After a little searching I finally even found something similar to Philadelphia / green. I am not quite sure, whether this is adequate food for the Caribbean, but apparently there is not just me here, who seems to like it. I also got me some Camembert, that together with some nice baguette will help me survive.

    For breakfast I got now müsli, corn flakes, and milk. And bananas, bananas, bananas, …

    Oooo, the milk is from France, not a local product. What a pity!

    BTW: If you ever want to see a garbage bin, just as clean as you breakfast table: come and see it here!

    I am not sure, whether I did that already, but I don’t want to forget to mention this:

    I love the Caribbean.

    Whenever I quote “Preacher 3” to people not familiar with the Torah, the Tanakh / Bible in general, I refer them to this song:

    There is a time for everything,
    and a season for every activity under heaven:
    a time to be born and a time to die,
    a time to plant and a time to uproot,
    a time to kill and a time to heal,
    a time to tear down and a time to build,
    a time to weep and a time to laugh,
    a time to mourn and a time to dance,
    a time to scatter stones and a time to gather them,
    a time to embrace and a time to refrain,
    a time to search and a time to give up,
    a time to keep and a time to throw away,
    a time to tear and a time to mend,
    a time to be silent and a time to speak,
    a time to love and a time to hate,
    a time for war and a time for peace.

  • the ISP doesn’t let you ssh

    Did that occur to you before? Your (new) Internet connection seems to work instantly, but then you recognize, that you do not succeed with ssh connections. (Search engine question: “Why does my SSH connection not work?”) That may have different reasons.

    1. The ISP block connections on certain destination ports like 22.
      If you can, get the sshd you want to connect to, to also answer on port 23 e.g. . You achieve this with an additional line like this in sshd_config there: “Port 23”.
      Usually the “Port 22” has not been explicit there so far, so if you add another Port line, you would also have to make that “Port 22” explicit, otherwise that sshd will not answer on port 22 any longer.
    2. The ISP does not like TOS flags in IP packets, that do not equal 0, or they just don’t like the TOS flag chosen by your openssh.
      The following bullets should actually be “2.1” …, but blogger doesn’t easily support this, and I am just to lazy to enforce it HTML-wise.
    • If you are using Linux and iptables, this may be your quickiest way to achieve this:
      iptables -t mangle -A PREROUTING -p TCP –dport 22 -j TOS –set-tos 0x0
      It did not work for me though, so I had to find another way.
    • I decided to adapt openssh to my needs, and here is the recipe:
      Get yourself an openssh TAR ball, unpack it, configure it!
      Add this line to config.h : “#define IP_TOS_IS_BROKEN 1” in order to leave the TOS flag untouched!
      Build it, and install it to a safe place, i.e. not necessarily to the standard place, so you will still be able to use the standard installation!
    • A friend of mine built himself a utility to run on the router (a FRITZ!Box 7050 router) and selectively adapt the TOS flag according to his needs.
      Migrating the utility to our FRITZ!Box 7390 models cost us too much time though, so we abandoned that solution.
      If you are still interested in this approach, he might forward his sources to you, so let us know!

  • just completed some part of my overseas communication with Europe

    I video-skyped with son#1 and his mother, and for the first time the timezone shift was the other way round: I was in broad daylight, and they at Berlin were already in the “darkness of the night”. Quite funny.

  • first things first on Martinique

    Got the router working and hooked up on the Internet again, before I went to bed. The customer’s ISP imposes non-default PPPoE parameters. which we sorted, but the ISP seems to not want SSH connections, so the packets need a change of tags. Against my hunger I am eating guave, nice baby bananas, and later avocado from the market. Phone battery went below 20%, and reminded me of getting home. I am going to post the journey story so far then. So return here a little later, funny and exciting things wait to get told and read.

  • FRITZ!Box 7390 “20002484” with Annex A and Annex B and English GUI – it’s available right now

    I got “mine” this afternoon, found it “somewhere” at the AVM headquarters like 10 minutes away from my place. I got officially numbered “1”. It’s going to get shipped to Martinique on Sunday (really!).

    It comes with a German 220V power supply, “but” with modem and telephone “Bell” adapters. So I guess, you will have to get an appropriate power supply adapter yourself, depending on your country.

    I would really love to keep one for myself, I love computers that talk to me in English, and a router/modem with Annex A wouldn’t be bad for the next holiday to “Annex A”-land. But then, the firmware for AVM’s flagship will always be best-maintained in German. And I do love to press the FRITZ!Box update button on my MT-F. A couple of minutes offline 3 times a week or even more often (you wouldn’t believe, how often they provide you with firmware updates!), and there you are: a newborn 7390!
