2019-03-19 Time to update putty 2 days ago
An interesting bit of news: SSH client gets patched after RSA key exchange memory vuln spotted.
The fixes implemented on PuTTY over the weekend include new features plugging a plethora of vulns in the Telnet and SSH client, most of which were uncovered as part of an EU-sponsored HackerOne bug bounty.
Get your updated putty at the PuTTY download page.

Update: Interesting visual change in putty: informational lines from the client are now prefixed by a putty logo. This could make it harder to mislead the user in certain attacks.

2019-03-17 Still working and sometimes struggling learning morse 4 days ago
Every week there is an hour of morse training at my radio club, see article CW cursus op PI4UTR (Dutch). And I'm going there every week I can, as learning morse is an important part of my amateur radio resolutions for 2019.

We're training with the G4FON morse trainer which uses the Koch method (order of characters to learn) to learn morse and so-called Fairnsworth timing (playing the dits and dahs of the characters at the high speed but leaving room to think about what you just heard).

I am doing ok, now we're getting to the level of 37 characters I have a hard time remembering the newest characters. Constant exercise seems the only way to fix this a bit, making exercises with just the characters I keep making mistakes in, although I can go blank again on new characters when switching to testing the whole set. As soon as I get reasonable low amounts of errors I'll try to raise the speed (by raising the effective speed, the dits and dahs of a single letter still come at 15 words per minute).

I want to learn this, with the plan to pass the Belgian CW test some day, and get up to enough speed to be able to participate in morse parts of contests and DX contacts. But there will be a lot of practice before I'm at that level.

2019-03-11 I participated in the EA PSK63 contest 2019 1 week ago
PSK63 contest in fldigi This weekend was the EA PSK63 Contest and I participated Saturday evening, Sunday morning and a bit Sunday afternoon. I planned to participate in this contest so I set up the endfed antenna outside Friday evening because I would be away most of the Saturday daytime.

With the current radio propagation and a serious part of my participation after sunset I decided to enter in the single operator 40 meter category. I made 106 contacts, with 25 different spanish provinces in the log (out of 52 possible province codes). Spain by itself has 50 provinces with Ceuta and Melilla not counting as a province but they do count in the contest.

I also participated in the EA PSK63 contest 2016 with 60 contacts and EA PSK63 contest 2018 with 125 contacts (but only 79 in the 40 meter band).

2019-03-08 Nieuwe experimenten met RFID kaarten 1 week ago
Na mijn experimenten met RFID kaarten in 2011 heb ik er een tijd niets aan gedaan. Het afgelopen half jaar kwam het onderwerp weer op door wat beveiligingsvragen rond RFID kaarten en heb ik weer de software uitgezocht.

Naast de linux tools is RFID support onder Android nu ook normaal en ik heb ontdekt dat NFC TagInfo by NXP prima software is om snel een kaart te onderzoeken. Bij sommige MiFare classic kaarten geeft deze software dan al een melding dat er standaard bekende sleutels ('factory default keys') gebruikt worden.

In vergelijking met 2011 is het wel anders dat Mifare classic kaarten met een wijzigbare UID (uniek kaartnummer) gewoon te koop zijn (zoek op 'UID changeable card') en de wijziging kan met nfc-mfsetuid wat onderdeel is van libnfc en dus bij een moderne linux uit package libnfc-examples komt. Een complete clone van een mifare classic kaart is dus prima mogelijk, zie bijvoorbeeld deze beschrijving: Cloning Mifare 1K cards (engelstalig).

2019-03-04 Terug van snowboard vakantie 2 weeks ago
We zijn een week op wintersport vakantie geweest naar het gebied van Serfaus-Fiss-Ladis in Tirol. Ons onderdak was een leuk appartement in Ladis, vlak aan de piste en we hebben ons prima vermaakt met snowboarden en een dag bergwandelen. Na een onderbreking van een paar jaar kan ik nog goed snowboarden en heb me ook weer vermaakt met boardercross en mooie afdalingen.

2019-02-27 Rare verandering in VDSL upstream snelheid 3 weeks ago
VDSL upstream snelheid week Ineens is de haalbare VDSL upstream snelheid (engels 'attainable') gezakt naar wat daarvoor ongeveer de huidige VDSL upstream snelheid (engels 'current') was. Een opvallende hik in de grafieken. Ik heb geen idee wat de aanleiding is en of dit weer kan veranderen.

Dit is alleen te zien in het modem, de hele PPP sessie is gewoon in stand gebleven.

2019-02-16 Received SSTV from the ISS 1 month ago
Slow scan TV transmitted from the International space station received by Koos van den Hout PE4KH on 2019-02-16 In this weekend there are extra slow scan tv (SSTV) transmissions from the international space station (ISS). The ISS moves across the sky when viewed from earth so I calculate beforehand when it will pass across the sky and what the trajectory will be.

I woke up in time to be outside for the first one. A low pass over the horizon and most of the pass matched a pause between transmissions, so not much image received.

2019-02-05 Starting tcpdump causes bluetooth drivers to be loaded .. on a virtual machine 1 month ago
I noticed something really weird in the kernel log of a virtual machine:
Feb  5 11:46:54 server kernel: [2936066.990621] Bluetooth: Core ver 2.22
Feb  5 11:46:54 server kernel: [2936067.005355] NET: Registered protocol family 31
Feb  5 11:46:54 server kernel: [2936067.005901] Bluetooth: HCI device and connection manager initialized
Feb  5 11:46:54 server kernel: [2936067.006404] Bluetooth: HCI socket layer initialized
Feb  5 11:46:54 server kernel: [2936067.006838] Bluetooth: L2CAP socket layer initialized
Feb  5 11:46:54 server kernel: [2936067.007280] Bluetooth: SCO socket layer initialized
Feb  5 11:46:54 server kernel: [2936067.009650] Netfilter messages via NETLINK v0.30.
Feb  5 11:46:54 server kernel: [2936067.056017] device eth0 entered promiscuous mode
The last two are the giveaway about what really happened: I started tcpdump to debug a problem. But I did not expect (and do not need) bluetooth drivers on a virtual machine, it will never have access to a bluetooth dongle.

After setting up /etc/modprobe.d/local-config.conf with
blacklist bluetooth
tcpdump still works fine and no bluetooth drivers are loaded.

Update: Most recommendations are to disable the bluetooth network family:
alias net-pf-31 off

2019-02-01 Plotting the number of amateur radio contacts after a contesting month 1 month ago
QSO count plot up to January 2019 After a month with three digimode radio contests I plotted the number of amateur radio contacts again. The number of contacts is clearly higher each January as a contest month, with this January a new peak.

The contests were the ARRL RTTY Roundup on 6 and 7 January, the UBA PSK63 prefix contest on 12 and 13 January and the BARTG RTTY Sprint Contest on 26 and 27 January.

Nicer looking font due to the upgrade of "radio workstation" thompson. I guess even gnuplot is coming along with the modern times.

2019-01-30 Misconfigured backups 1 month ago
I have "always" been running amanda for backups on linux. Or rather, I can't find any indication when I started doing that several homeserver versions ago, it's just still running.

Or it was running, but first I had to tackle a hardware problem: all SCSI controllers I have are PCI and the newest homeserver has no PCI slots. So I searched for a solution. The first solution was to try using the desktop system for the tapedrive, but the powersupply in that system has no 4-lead Molex connectors so I can't connect the tapedrive.

For now I use an old 'test' system with some software upgrades to run amanda and shut it down when all backups are done and flushed to tape. But amanda had a serious problem writing stuff to tape. With some debugging this turned out to be caused by the variable blocksize I used on the previous systems, with
# mt -f /dev/nst0 setblk 0
and I can't even find out why this seemed like a good idea years ago. But now amanda really wants to use 32768 byte blocks and filled a DDS-3 tape (12 Gb without compression) with about 1.8 Gb of data before reaching the end of the tape.

Why this default has changed isn't clear to me, but I found a way to re-initialize the tapes so the backups fit again. Based on block size mismatch - backup central I created a script to do this. I did not get the error about the blocksize, but I searched specifically for 'amanda 3.3.6 blocksize'.

if [ "$1" = "" ]; then
        echo "Usage: $0 <tapename>"

mt -f /dev/nst0 setblk 32768
mt -f /dev/nst0 compression 1
mt -f /dev/nst0 rewind
dd if=/dev/zero of=/dev/nst0 bs=32768 count=200
mt -f /dev/nst0 setblk 32768
mt -f /dev/nst0 compression 1
mt -f /dev/nst0 rewind
amlabel -f kzdoos $1
And now normal amounts of data fit on a tape again. I just have to initialize every tape before using it for the first time in this setup.

2019-01-29 (Last post to be automatically imported into For years I automatically imported ...) 1 month ago
Google+Koos van den Hout : Last post to be automatically imported into

For years I automatically imported posts from google+ into my homepage at and made them available on my own timelines.
This is one of the things about Google+ I like: it's relatively easy to get access to the content and use it in other places.

Google+ does not have (did not have) the tendency to suck in your data and keep it shielded from the outside world. This is why I liked it over other social networks.

I don't expect a social network to keep things I post private. There's always that stalker in the back of my mind when sharing things online. So anything I post is completely public anyway, no need to keep it locked in. If I post a solution to some problem it's for anybody to read. And laugh at, snicker, or maybe use the solution.

Byebye Google+ API. You will be missed.
2019-01-27 I participated in the BARTG RTTY Sprint Contest 1 month ago
RTTY contest on websdr This weekend I participated in the BARTG (British Amateur Radio Teledata Group) RTTY Sprint Contest.

I went into this contest with the idea of maybe getting some contacts and things turned out somewhat better than that: I made 82 contacts. No new countries or anything else special. The one that got away was PJ4P, Bonaire. I saw that station calling and I kept answering but the contact did not happen.

I used the topendfed antenna outside and the amplifier. So I entered in the high power category.

As with other recent contests the propagation wasn't cooperating very well. When I started in HF at home (October 2014) I would switch from 10 to 20 meters after it got dark because of the changing propagation. Now I change from 20 to 40 meters as soon as it starts to get a bit dark.

2019-01-14 I participated in the UBA PSK63 prefix radio contest 2 months ago
PSK63 contest in fldigi Like in 2015, 2016, 2017 and 2018 I participated in the UBA PSK63 Prefix Contest in the past weekend. Before I really dove into the contest I first mounted a new end-fed 10/20/40 antenna which can handle more power and tested it.

It took a few tries to get the antenna tuned on the 40 meter band. I tested this with the amplifier which has proven to be really precise about the SWR of the antenna in the 40 meter band, as noted in my post about the ARRL RTTY roundup 2019. I had planned to get this antenna up and running before that contest but that did not work out.

After testing I switched back to 50 watts power without the amplifier because the rules of the UBA PSK63 prefix contest limit the power.

I made a total of 69 contacts as single operator 40 meter. I had a short look at PSK63 activity in the 20 meter band during daylight but it was completely none.

After the contest I tried some FT8 contacts on the 40 meter band with the amplifier active. The amplifier did not like this and went into SWR protection. I must have tuned it perfectly for 7.040 - 7.050 MHz but the SWR is already outside the limits for the amplifier at 7.074 MHz.

2019-01-12 Enabling some old web userdirs 2 months ago
I received a "complaint" that a very old site on the webserver wasn't working anymore. I am not a person to just stop something without planning that so this was an oversight. It was one of the userdirs on Ivo van der Wijk who hasn't updated the page sinds 1994. No, really, not even the broken links.

In restoring this one and the others I found that php in userdirs is disabled by default nowadays, found via PHP not working in userdir (public_html) - devPlant. Maybe a good idea, but I only enable php on virtualhosts where I want it, so I disabled that rule. I hadn't missed it on my own webspace yet, but a site like Het online dagboek van hester (Renate) in Australie (en daar in de buurt) depend on PHP completely.

While I was looking for the reason the php failed I also noticed that /etc/apache2/mods-available/userdir.conf also has some configuration I do not appreciate, it enables userdirs globally when the module is loaded:
<IfModule mod_userdir.c>
        UserDir public_html
        UserDir disabled root

        <Directory /home/*/public_html>
                AllowOverride FileInfo AuthConfig Limit Indexes
                Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec
                Require method GET POST OPTIONS
I disabled that part: I only want the userdir to work on specific virtual hosts.

2019-01-08 Amateur radio resolutions for 2019 2 months ago
The last time I did those was in 2017: Reviewing my 2016 amateur radio resolutions, and the new ones for 2017 and the hindsight results for 2017/2018 are:
  • Improve the holiday/portable setup with solar power and a lightweight multiband inverted V
    No solar power (due to costs) but the portable setup is improved and tested: the fiber mast I bought for playing radio from several locations including amateur radio from a local park. Now to find more time to actually use it.
  • Keep doing the digimode contests
    That part went better in 2017 and I had less time and/or energy for contests in 2018. Also in 2018 the interference situation got worse. So my net results in contests improved in 2017 and got worse in 2018.
  • Maybe those satellites
    I tried at least receiving them a few times, but no contacts yet.
  • Get a 2m/70cm vertical antenna on the roof of the dormer
    It's there, it has already been upgraded to a bigger antenna with higher gain and it's mostly used for 2 meter FT8. But also for actual talking to other radio amateurs sometimes.
The Sotabeams newsletter had an item "Setting your targets for 2019" which had some nice ideas and which triggered me to write this post. Things I want to try :
  • Keep learning morse!
  • Get more countries on more HF bands in the log
  • Moonbounce on 2 meter
  • Those digimode contests, and maybe a few phone contests
  • Operate HF outside
  • At least one satellite contact

2019-01-07 I participated in the ARRL RTTY Roundup 2 months ago
RTTY contest on websdr As planned I participated in the ARRL RTTY Roundup contest this weekend. It was possible to participate in FT8 mode but since I had not prepared for that and had no duplicate checking between FT8 and RTTY I decided to use the mode I am familiair with for this contest: RTTY.

I operated on the 40 meter band Saturday and Sunday evening, and on the 20 meter band during the daylight hours of Sunday. Everything was search and pounce, no responses to calling CQ. I used the power amplifier on the 20 meter band which did help in getting the contacts to almost every station I could decode. The amplifier does not like the SWR from the antenna on 40 meters so I ran without the amplifier on that band.

I made 115 contacts. A number of US stations, already the first new US state confirmed via LoTW. Two more new US states in the log, hope I can get those confirmed too.

2019-01-02 Migration to new server finished 2 months ago
More than a year after I started migrating from homeserver greenblatt to the new homeserver conway the last migration is done and the old server is switched off. The new server is in a good position in the rack, and the old server is still taking up space in there too. It has taken a lot of time, I decided to stop some websites and other unused services in the process and my energy levels haven't always been that great. I have improved several things in the process, which also caused delays.

One thing hasn't changed (which I did expect to change): the power usage of the new server isn't lower! The UPS tells me the output load is about the same. Ok, the new hardware has a lot more CPU power, a lot more memory and faster storage, but I expected the poweruse to go down a bit.

2019-01-01 Switching to 1-wire over USB and forwarding a USB device to a guest VM 2 months ago
The new hardware for the homeserver has no external serial ports, so I could not use the old serial / 1-wire interface that has been doing the home monitoring for years. But I had a spare USB DS2490 interface. So I plugged this into the server and wanted to forward the USB device to the guest VM that runs all the monitoring.

First I had to blacklist all the loaded drivers to have the device available to kvm as-is. In /etc/modprobe.d/local-config.conf:
blacklist w1_smem
blacklist ds2490
blacklist wire
Next step was to attach the device to the right vm. I followed the hints at How to auto-hotplug usb devices to libvirt VMs (Update 1) and edited the definition for the vm to get the host device like:
    <hostdev mode='subsystem' type='usb' managed='no'>
        <vendor id='0x04fa'/>
        <product id='0x2490'/>
But that did not get the usb device attached to the running VM and I did not feel like rebooting it. So I created an extra file with the above and did a
root@conway:~# virsh attach-device --live gosper /tmp/onewire.xml 
Device attached successfully
And then I had to do the same blacklisting as above in the virtual machine. After doing that I detached and attached it from the VM without touching it with simply:
root@conway:~# virsh detach-device --live gosper /tmp/onewire.xml 
Device detached successfully

root@conway:~# virsh attach-device --live gosper /tmp/onewire.xml 
Device attached successfully
After that I had to set up rules for the telemetry user to have enough access to the USB device:
SUBSYSTEMS=="usb", GOTO="usb_w1_start"
ATTRS{idVendor}=="04fa", ATTRS{idProduct}=="2490", GROUP="telemetry", MODE="0666"
And now it all works:
