2020-03-25 It's 2020 and github doesn't support IP version 6 2 days ago
Several of the machines here at home have IPv4 to the outside world disabled, simply to improve security and find every ancient service or program that still lives in the old world. Today I found one of those while installing dehydrated to automatically renew Let's Encrypt certificates.

Indeed, github has no IPv6 support. It tries to be a modern service, but lacks an AAAA record.

The one reason I still have a squid webproxy running is to be able to access IPv4-only services from those hosts, so setting the http proxy in the global git config helped. I'm just surprised github doesn't support IPv6.

Update: After some searching I found Github users have been asking about IPv6 connectivity since at least 2018 and the "solution" is that they currently don't support IPv6 and the request is on some list.

2020-03-17 I participated in the EAPSK63 contest 2020 1 week ago
PSK63 contest in fldigi Last weekend was the EAPSK63 contest and I participated on Saturday. Lots of stations from Spain active and I managed to work 29 unique Spanish provinces. A total of 82 contacts. I could only participate Saturday afternoon and evening so that limited my time in the contest.

2020-03-13 Frastanzer s'honig 2 weeks ago
Beer illustration I bought a few Frastanzer beers on our snowboard holiday in Austria.

The first one to try is "Frastanzer s'honig" which is a beer made from biological ingredients with indeed a bit of added honey. Not too much, it's not too sweet for my taste. The honey gives the beer a soft side in taste without losing the strength from hops completely.

2020-03-09 Newer power supply not yet delivering what I want 2 weeks ago
I did some more testing with the HP power supply I bought last November. In previous tests the output voltage seemed to be limited at 13 volts and it seems limited to 13.10 volt at the moment. The RM Italy HLA300V plus amplifier I have will only output about 55 watts maximum in digital modes so that's less than I expect. A higher input voltage may fix this, but I'm not sure how to get the power supply to deliver this and keep running. The previous power supply gave up in a busy weekend but before that the HF linear amplifier delivered more power. I have seen it go over a 100 watt on digital modes. The difference in output from the linear amplifier with 13.10 or 13.27 volt power is quite large, which surprises me.

2020-03-08 Updating the Fritz!box 7360v1: still no PPPoE passthrough 2 weeks ago
A while ago I noticed a mention of new firmware for the Fritz!box 7360v1. As I want a separate PPPoE process to have full control of my Internet connection I hoped the PPPoE passthrough option would become available, since this would be a firmware version later than 6.30, but no.

At least the upgrade went fine without having to use the recovery options. So the 'in case of emergency' settings have been kept forwarding the necessary ports via IPv4.

2020-03-03 Adding contact e-mail addresses to letsencrypt accounts via dehydrated 3 weeks ago
Encrypt all the things meme I noticed the news about LetsEncrypt revoking a lot of certificates on 4 March 2020 and did some checking to find out eventually that one of my certificates is in that set. Users have been notified of this problem... when their account had a contact e-mail address. By default dehydrated doesn't set an e-mail address so none of my instances used one. I do like to get informed so I searched how to update the contact info. The data is in /etc/dehydrated/config field CONTACT_EMAIL but I needed some searching before I found the method to get the update passed on to LetsEncrypt.

Some searching later found Update registration email address - Issue #425 dehydrated which shows that a simple dehydrated --account does the magic.

2020-03-02 Trying amateur satellites between the mountains with snow falling 3 weeks ago
During our wintersport holiday in Austria I also brought my Arrow antenna and handheld radios along to try a satellite contact.

Before the holiday I read on twitter that Peter Goodhall 2M0SQL has unconfirmed gridsquares which included the place I was going on holiday. So I prepared for trying to make the contact during the holiday. In the preparation I got a theory why I had problems with the satellites with a 2 meter downlink frequency.

During the holiday I soon figured out there wasn't a lot of time for contacts, during the day we were on the pistes and we went to bed early because we had a lot of physical activity. And the place we stayed was between the mountains so for satellite passes I was limited to high passes.

In the end I did listen to one Fox-1D pass which was high and long enough. In a serious amount of falling snow so that was a new experience in amateur radio: trying to make contacts in the snow. Reception of Fox-1D was quite good on the Baofeng UV-5R radio, but transmitting back up didn't work out, I never made a contact.

I did not hear Peter on that pass, so that did not work out at all. But I learned several things, including the fact that the theory about the 2 meter downlink frequencies and the Wouxun KG-UVD1P was correct so the result is positive anyway.

2020-03-02 Back from snowboard holiday 3 weeks ago
Last week we were on a wintersport holiday in the Montafon region of Austria. I went snowboarding and had fun. There was enough snow at higher levels when the week started and later in the week it started snowing giving fresh snow which I really like for snowboarding.

Driving to Austria and back home through Germany went fine, no huge traffic jams or really bad weather. There is still a lot of work on the German Autobahns but less than one or two years ago. The lane departure warning system in our car still doesn't like the mix of orange and white lines on the road when lanes are shifted for work.

2020-02-20 I think I figured out why I didn't hear satellites with 2 meter downlink 1 month ago
I was preparing for trying some satellite contacts and noticed the Fox-1B and Fox-1D had nicer opportunities for a contact. But I always have problems receiving any signal from those satellites on the handheld radio that I use for satellite contacts, which is the Wouxun KG-UVD1P I got for Christmas in 2012. Not the ideal radio for amateur satellites, but easy to bring along and to program with split frequencies.

A while ago I noticed that radio was constantly receiving noise on the 2 meter band and I had to set the squelch level quite high to stop it. I thought it was some local overload or local noise in the 2 meter band. But today while working on the preparations for some satellite contact possibilities I figured the problem is with the radio and something is actually wrong on the 2 meter receive side.

I have two other handheld radios. One is a Kenwood TH-D7 where I can't change the squelch level so it's not really usable for satellite contacts and the other is a Baofeng UV-5R which can't be programmed via the computer.

So I spent a lot of time entering all the possible doppler-shifted frequencies of both satellites on the keypad of the Baofeng UV-5R. I hope that gives me a working radio for Fox-1B/Fox-1D and I can get a few new contacts in the log.

Update 2020-02-27: I was correct! I tried a Fox-1D pass with the Baofeng UV-5R radio and I had easy reception of the satellite. Trying to get my signal over the satellite didn't work, but at least I know what the reception problem was.

2020-02-17 Tweaking the SSL cipher settings for 2020 1 month ago
Encrypt all the things meme A few days ago I changed the configuration of haproxy to stop accepting TLSv1.0 and TLSv1.1. With the upcoming deprecation of TLSv1.0 and TLSv1.1 this seemed the right SSL configuration. Today I remembered there is one directly reachable Apache server, so I had a look at the settings there and checked the results with the Qualys SSL Labs SSL Server test where I noticed some ciphers listed as 'weak'. And seeing different results between my haproxy and apache servers, which I did not expect as I used the same settings for SSLCipherSuite in Apache and ssl-default-bind-ciphers in haproxy.

The last issue was caused by the fact that Apache2.4.25 in Devuan ascii uses libssl 1.0.2 and haproxy 1.7.5 uses libssl 1.1.0. I'm not sure that's an ideal configuration but it's what I work with.

With the output of openssl ciphers -v I get a list of cipher names. But this is with libssl1.1.0 so the output lists ciphers that Apache doesn't have access to (yet). The good part is that Apache ignores ciphers that aren't available, so the net result is a running and working configuration.

The current result is for Apache 2.4.25:
SSLProtocol All -SSLv2 -SSLv3 -TLSv1 -TLSv1.1
SSLHonorCipherOrder on
SSLCipherSuite ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES128-GCM-SHA256
And for haproxy 1.7.5:
ssl-default-bind-options force-tlsv12 no-tls-tickets
ssl-default-bind-ciphers ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES128-GCM-SHA256
The fun part is that I can test the SSL negotiation with sslscan locally but sslscan is linked against openssl 1.0.2 so it misses some of the newer options. And I also test with the Qualys SSL Labs ssl test but that takes a while.

The too long; didn't read version of finding the right configuration options

And later I found I could have saved a lot of time researching options using the Mozilla SSL Configuration Generator. I don't completely agree with the suggestions there because I want to generate my own dhparams. Using 'well-known Diffie-Hellman paramaters' has security risks. But otherwise all the suggestions for ciphers are very usable and save me a lot of time.

2020-02-16 Reconsidering data gathering and processing 1 month ago
For years and years I've been doing a lot of data gathering and storing the data using rrdtool. Data such as temperatures from lots of places, from mainboard CPU sensors to an outside weather station, other weather data, web traffic data, house electricy and gas usage, solar power. I started doing this with mrtg in 2001 and switched to rrdtool.

There are some improvements to this system, such as maintaining the rrd files on one machine and doing measurements on other machines in the form of timestamped files to be transported to the machine with rrd via rsync-over-ssh. This allows the central database to do a catch-up of decentrally gathered data after an interruption.

All in all there are two disadvantages at the moment: the system isn't very flexible, adding a datasource means making the big decision about how much data to keep how long and what I want to look at.

Diskspace isn't as constrained as it once was, I may want to keep some data forever and I may want to zoom in to a period a bit longer ago. So I'm looking at different solutions. For one dataset I already added an alternate datastore: the electricity and gas meter readings get copied to a postgres database once a day so I can look at the daily readings forever.

So the search is on for the ideal solution. For gathering and transporting data I am looking at mqtt, a lightweight protocol to gather and transmit data. This also makes it easier to have multiple data collectors look at one source so I can test with a few things first before I make a real switch to any new system.

2020-02-15 Active on the 60 meter amateur band again 1 month ago
I had one whole contact on the 60 meter band a few years ago with a German station. This band is supposed to be outside of the reach of my longwire, but with a lot of tuning it can work.

This weekend the longwire and the tuner absolutely did not want to get to a workable state on the 80 meter band so I tried the 60 meter band again. In FT8 mode, as that is what gets me the most result from home outside of contests.

This got me a number of contacts. Also one new country already confirmed: Tajikistan. And a new country with a questionable contact, so I'm waiting to see whether the other side will confirm or not. Formally 60 meter doesn't count for ARRL DXCC, but to me every contact counts in some way. I even got stations responding to me before I called CQ, I guess some amateurs are keen on getting a new callsign in the log.

I took down the wire antenna Saturday early in the evening because the winds were picking up for another storm.

2020-02-10 Getting with the times and limiting the webserver to TLSv1.2 1 month ago
In 2020 the support for TLSv1.0 and TLSv1.1 will end so the famous qualys SSL test is giving capped grades. I decided to get with the times and limit my outside web ports to TLSv1.2 so now I am back at an A+ grade.

Eventually this will start to cause problems as Devuan stable doesn't have an openssl with TLSv1.3 support yet.

2020-02-08 Lagunitas India Pale Ale 1 month ago
Beer illustration I decided to look for some special beers while shopping and I found this one: Lagunitas India Pale Ale. Sounded good, so I bought it.

The first taste is mostly hoppy, as expected from an IPA. Stronger than I've seen in some other IPA beers. In general it has a strong hop influence in the tast and reminds me of English bitter beers.

Reading the label shows me Lagunitas is from Petaluma, California and Chicago, Illinois. I guess Chicago has a serious beer culture with multiple breweries.

2020-02-08 Still learning morse, getting some help 1 month ago
I'm still working on learning morse code. Sending morse code with the paddle is going ok at about 10-12 words per minute. Receiving is also somewhere around that rate, but I make more errors receiving.

I practise receiving morse with G4FON (Windows), xcwcp (Linux) and IZ2UUF morse trainer (Android). G4FON offers Farnsworth timing, where the letters are transmitted at a higher rate but there is extra spacing between letters to lower the rate of transmission. In xcwcp I can add extra dots between letters and in IZ2UUF morse trainer I can set extra length as a factor of the letter length. Three somewhat different methods to help learn morse at a reasonable speed.

To practise sending morse I use either the FT-857 radio or the control unit of the remote radio as expensive morse sounders. For the morse training at the radio club this is somewhat bulky and the internal buzzer of the nanokeyer is not loud enough so I ordered a practise oscillator kit from Kent morse equipment in the UK.

I also joined The Less Involved Data Society where I hope to meet newcomers to morse on the air. So I am now LIDS member number 414.

And for the rest: practice, practice, practice. Changing between modes of practice such as whole words in English or Dutch or back to random characters or groups of 5 letters helps improving speed and accuracy.

2020-02-04 Chasing more DX with HamAlert 1 month ago
This weekend I had some random radio time so I made a number of contacts. By numbers mainly in FT4 and FT8 but also some SSB and CW via the remote radio.

I activated HamAlert triggers and used that to get a few countries in the log that I wanted confirmed via LoTW. This worked for Corsica and San Marino. I got an alert for a San Marino call on Saturday and worked it reasonably fast after an FT8 CQ from that station.

On Sunday I saw a notification for a Corsican call on FT8. When I saw the activity I noticed the station was just calling other stations. So I just started answering the callsign in the hope of getting the contact and after a few tries the hint came across and I got the contact in the log.

This is an area where an alerting system that uses more sources than just the DX cluster network works better: the station from Corsica never showed up on the DX cluster, but the activity was seen by PSKreporter and filtered by HamAlert into a notification to me.

The contact with Corsica is already confirmed on LoTW.

2020-01-30 Backup to a remote webdav server, first success! 1 month ago
I found a completely different option for transferring files from linux to a remote webdav filesystem: fusedav. Mounting the remote 'cloud' disk with fusedav and synchronizing files with rsync is starting to work.

I decided to split my backups into two categories: first there are file collections that usually only grow, like digital camera pictures and audio project files. This takes the most diskspace and doesn't really need versioning.

The second category is configuration files, homedirs, mail and other things that change and where I may need an older version. This is where backups based on amanda work better.

I mount the filesystem with:
$ fusedav -u koos -p topsecret https://webdav.cloudprovider/remote.php/webdav/ /home/koos/webdavmount/
And the rsync command to backup to this mount:
$ rsync -av --progress --bwlimit=512K --size-only --timeout=30 /camera/2003/ webdavmount/camera/2003/
This looks scriptable so it can run on a regular basis with just a status update to me.

Update:
Reliability is still an issue. I added the --timeout=30 parameter to make rsync abort when the bytes stop flowing.

I always get the error for 2001:878:346::116 when connecting. This site seems to have a problem with the devuan mirror at the moment, so I'd like to use another one, but apt keeps going back to the same source. This has to do with IPv6 address destination selection (RFC 3484 / RFC 6724).

A good explanation at IPv6 Destination Address Selection – what, why, how - Karl Auer with:
Rule 9, “use longest matching prefix“, will prefer the candidate destination address that shares the greatest number of contiguous leading bits with the source address that would be chosen for it. Such an address is likely to be topologically closer to the source address.
Indeed that address is close to my home network addresses:
2001:0878:0346:0000:0000:0000:0000:0116
2001:0980:14ca:0001::/64
So the "roundr" round robin isn't very round for IPv6 users.

Workaround: reject the address that is giving me problems:
# ip -6 route add unreachable 2001:878:346::116
# apt update

2020-01-21 Suricata and ppp: restart of suricata needed after ppp down/up 2 months ago
Suricata is running and detecting attacks, but it was causing a 100% cpu load after a restart of the ppp connection (the DSL here uses PPP over Ethernet).

The errors point at the problem starting when the ppp connection restarts:
21/1/2020 -- 00:59:36 - <Error> - [ERRCODE: SC_ERR_AFP_READ(191)] - Error reading data from iface 'ppp0': (100u) Network is down
21/1/2020 -- 00:59:37 - <Error> - [ERRCODE: SC_ERR_AFP_CREATE(190)] - Couldn't set fanout mode, error Invalid argument
Which also starts to fill the system log with:
Jan 21 00:59:42 xxxxxxxx kernel: [11347441.726755] device ppp0 left promiscuous mode
Jan 21 01:00:13 xxxxxxxx kernel: [11347472.055712] device ppp0 entered promiscuous mode
Jan 21 01:00:13 xxxxxxxx kernel: [11347472.071533] device ppp0 left promiscuous mode
Jan 21 01:00:13 xxxxxxxx kernel: [11347472.091653] device ppp0 entered promiscuous mode
The interesting part is that this causes higher power usage about five and a half hours later.

Solution: restart suricata in an /etc/ppp/ip-up.d/ script.

2020-01-17 Added the javascript IPv6 test 2 months ago
With very little javascript programming experience I managed to program a version of the IPv6 inline test that is what I wanted for a while: a simple IPv6 check in the right hand column of my homepage. With credit to the IPv6 test by Iljitsch van Beijnum. A needed test, because we really ran out of IPv4 addresses.

It took a lot of tries and debugging because I have absolutely zero javascript experience. But I learned slowly and managed to get what I want.

This is where I like having test environments. There were a lot of broken versions of the test on a separate minimal test page, then I implemented it on the developer version of my homepage and fixed the last errors in that combination and after that I committed the change to the versioning system and updated the production version which showed the update without problems in one go.

2020-01-13 I participated in the UBA PSK63 prefix contest 2 months ago
PSK63 contest in fldigi Like in previous years I participated in the UBA PSK63 Prefix Contest in the weekend.

Overall it was a nice contest, with 111 contacts in total which makes this a good contest score. I started in the 20 meter band on Saturday, moved to the 40 meter band after propagation died down due to the sun going down.

On Sunday morning I started on the 40 meter band but soon gave up, there was a lot of interference on that band. I switched to 20 meters and made some more contacts. In the end: 38 contacts in the 20 meter band and 73 in the 40 meter band.

2020-01-08 Changed to a new alerting option for radio amateurs 2 months ago
I turned on the remote radio today and saw in the DX cluster that the ZC4UW dxpedition was still active although 7 January was the last day.

The signals were never good enough to make the contact, but this made me rethink the DX alerting options I have. I used 'DX Alert' on Android before, but this program had some difficulties and I can't find it anymore on the google play store which suggests it's really going out of support.

The new suggestion is HamAlert which processes data from the DX Cluster network, PSKreporter, Reverse Beacon network and Sotawatch, allows the user to set triggers and report via push notification to a Android/Iphone when the HamAlert android app or equivalent iPhone app is installed.

I created an account, installed the app and set up my first triggers: countries in and around Europe I don't yet have confirmed in bands/modes that I can use. It's a lot easier in HamAlert to set these up compared to DX Alert because it can all be done on the HamAlert website and can be customized more easily.

Update 2020-01-12: First score: I activated the alerts today because I had some time to get on the radio between other things. I saw alerts for E44RU which is in Palestine on a non-standard FT8 frequency. I spun the dial, adjusted a bit and made the contact. And that's a new country for me.

2020-01-06 I participated in the ARRL RTTY Roundup 2020 2 months ago
RTTY Contest on websdr This weekend was the ARRL RTTY Roundup edition 2020 and I participated. Late Saturday evening I saw a few US stations come up on 40 meters. Sunday afternoon I made a lot of contacts to mostly European stations on 20 meters. In the evening after dark the contacts from Europe seemed to stop after the first 24 hours were over but when I checked again late in the evening more US and some Canadian stations were decoded on my end and I worked them.

In the end 110 contacts, a nice score for this contest. Claimed score: 110 qso points * 33 multipliers = 3630.

The one that got away: I saw a station from California calling and giving state 'CA' in contacts, but he never heard me. That's the first time I heard or saw anything from one of the western US states.

2020-01-06 Security tools can help practise morse 2 months ago
Today I needed blocks of random letters to practise sending morse. What better tool to create those blocks than good old pwgen with the right settings:
$ pwgen -0 -A 5 12
ahhud eizaa kuoku ahyoo aequi epiis eiwei eimap sohsh papai ikeit oucho
And the trick for generating groups of five digits is a bit longer:
$ pwgen -r abcdefghijklmnopqrstuvwxyz -A 5 12
97228 85996 98876 38451 06091 98556 53369 73632 29509 29032 89601 16078
Use better parameters with pwgen to generate actual passwords.

2020-01-03 No longer amazon.com associate on The Virtual Bookcase 2 months ago
I received a message from amazon that The Virtual Bookcase no longer qualifies as an amazon.com associate. That was no big surprise as I haven't done a lot of maintenance on the site and haven't added a lot of content in the last years.

The only serious maintenance was for the migration to the new web server where php 7.0 is the standard version. I wish to some day migrate to perl but haven't found time yet.

So I removed all amazon affiliate links I could find. This also means I can't use the amazon.com API anymore.

2020-01-01 Closing 2019 in amateur radio, time to plot the number of contacts and look back 2 months ago
QSO count plot up to December 2019 Time for a new plot of the number of radio contacts. Months with contests are quite visible. After the peak in number of contacts in July there was first a holday and after that no big peaks in number of contacts. December 2019 jumps out a bit again due to the FT8 roundup on 8/9 December in which I made 66 contacts and later in the month the troposperic ducting allowing contacts over interesting distances in the 70 centimeter and 2 meter band added to a sprint at the end. In 2019 I made a few more contacts than in the previous record year 2017.

Looking back at my amateur radio resolutions for 2019 I think most came true.

If I look at them one by one:
  • Keep learning morse! - I'm still working on my morse, but there is measurable improvement. I have learned the full set for the Belgian CW exam and I'm working on accuracy and speed.
  • Get more countries on more HF bands in the log - More countries and more slots on HF are in the log. I also use the club station to achieve that goal. The ARRL DXCC Award shows that I'm getting somewhere.
  • Moonbounce on 2 meter - I've listened on the right frequencies to the moon on 2 meter. Nothing heard.
  • Those digimode contests, and maybe a few phone contests - I participated in two phone contests and a number of digimode contests. No serious improvement in scores.
  • Operate HF outside - I operated HF outside. Not as much as I would like.
  • At least one satellite contact - Multiple satellite contacts have been made!
Now I have to think about 2020, but the year is still young.
