ble at assembling miniatures i mean i am even worse at painting them but i usually only buy one piece miniatures because i know about my distinct lack of skills oh well wish me luck now where s that glue posted by peter fröhlich at 4 04 pm no comments email this blogthis share to x share to facebook share to pinterest friday june 11 2021 third grade memory i just made a forum post elsewhere and realized that i should push this third grade memory of mine out here as well don t worry about the context in like third grade in the winter after school before heading home we d go over to the church lots of low curved walls with snow on top there we d sketch buttons and screens and stuff into the top of those walls and we d play out some star trek re run from the night before someone was kirk and someone was scotty and so on we decided on the fly what we could and could not do and what would happen we did this for about thirty minutes to an hour then went home for lunch and homework and comics and stuff when we played next a day or two later we d keep some of the decisions we made before others we redid new episodes added new information etc nobody wrote any of that down despite us having a grand old time for weeks of school plenty here that sort of dates this of course kids these days don t seem to get out of school around lunchtime anymore instead they are forced to do pedagogically sound stuff that others thought up for them in the afternoon and if that wasn t sad enough if one of them would actually complain about not liking those well designed exercises they d get some kids level psychoanalysis next week oh well i guess it s progress posted by peter fröhlich at 8 35 pm no comments email this blogthis share to x share to facebook share to pinterest wednesday november 11 2020 let s hope i am wrong but i fear i might not be looking at everything that s going on with trump and his cronies right now i cannot help but think that their plan is to drag it all out until some state legislatures have to select electors in order to not miss the safe harbor deadline and of course republican state legislatures will pick the republican slates combined with another group of cronies waiting in the wings of the pentagon the fbi and the dhs for crowd control it will be the coup trump has been playing for all along he ll finally be able to join the ranks of his pals in other authoritarian societies and keep on ruling until junior eventually succeeds him on the upside we ll actually live in interesting times just as the old chinese curse said cheers posted by peter fröhlich at 10 20 pm 1 comment email this blogthis share to x share to facebook share to pinterest tuesday august 11 2020 openbsd ipv6 on tinykvm i had a lot of trouble getting ipv6 to work under openbsd 6 7 on a tinykvm instance so here for reference is how i finally made it work in your control panel note the ip addresses for your instance and its gateways for the ipv6 address of your instance you get to pick the last 16 bits yourself but obviously you can t pick the ipv6 of your gateway edit etc hostname em0 and put in the ipv4 keyword inet and ipv6 keyword inet6 addresses and netmasks for your instance nothing else edit etc mygate and put in the ipv4 and ipv6 addresses for your gateways nothing else stop and disable the slaacd daemon using rcctl i guess the openbsd folks are hopeful that most networks support slaac but i had no luck here try restarting the network using sh etc netstart but if that doesn t fix things for you reboot the instance and hope for the best note that i had to add a mystical invocation of ifconfig to etc rc local as well without that the instance wouldn t pick up either of its ips immediately on boot but only after a roughly 5 minute delay no idea what the tinykvm folks are doing there but hey with this all static configuration and the weird ifconfig trick things now work roughly as they should if you figure out a better way of doing this please let me know posted by peter fröhlich at 1 04 pm no comments email this blogthis share to x share to facebook share to pinterest sunday july 5 2020 hosting options for various reasons i ve been looking around for new vps hosting options again this is a brief summary of the neat things i found it s not a review of any kind it s literally just a bunch of links and commentary if i ever use any of these options for long enough to have an opinion i ll add a review or three historically i ve mostly used linode especially back in the day when i was running lots of game servers across the us and even in the uk for a while my longest running shared server is also on linode they have some great tech nice support and it s generally very smooth sailing indeed but there are issues as well especially these days first they don t have a cheap storage option everything is nvme ssds these days and so with a small plan what i usually run because i am cheap you get 25 gb not too shabby if you grew up in the 1970s but not great either after a bit of research i noticed that ramnode actually offers plans with good old spinning rust disks yes the kind some of you don t even remember as of today you can get 160 gb for 3 month and 325 gb for 5 month pretty sweet if all you need is a bunch of space for automated backups for example of course you need to keep an eye on bandwidth but hey here s the storage if you need it another issue is that us companies are well us companies just like german companies are german and australian companies are australian doh what i am getting at is that by picking a hosting company you re also picking to a degree the laws that protect or not your data privacy freedom or life so depending on what you plan on doing with your vps you may want to pick an exotic jurisdiction instead of the obvious one i ended up looking at switzerland austria and iceland in more detail from a five or more eyes perspective these are places that at least have no overt history of large scale illegal spying they also have reasonable press freedom rankings which can be helpful if you plan to do some investigative reporting online but don t forget the small print of your vps provider either different companies have vastly different terms of service regardless of the level of freedom that exists in their respective countries also these things are never as simple as shoving your data or services elsewhere so if in doubt get yourself a lawyer for me 1984 hosting in iceland checks most of the boxes i care about also their pricing is a lot better than many other vps vendors in iceland for example they have a reasonable 5 month plan that s actually comparable except for bandwidth with a cheap linode plan on top of that i was impressed by their recent report on a 2017 incident that brought down much of their operation yes maybe it s a little late but it s certainly detailed and i very much like the idea of them trying to be this transparent about what happened why it happened and what they ve done to avoid it in the future a final issue is operating systems it s kind of a pain or at least it used to be maybe it improved recently to install openbsd on linode yes i ve been mostly a linux person for the past 15 years or so but i ve recently tuned back into the bsd world a bit more and i like what s happened there i currently run openbsd on a small vultr instance and that works reasonably well but i also found a small outfit in amsterdam that not only offers openbsd vms but also uses openbsd to run the virtualization infrastructure itself on top of that they donate to the openbsd developers their pricing is yearly and works out to 5 month for a small vm half the ram of linode but twice the disk space that s it for me and hosting for now feel free to share any hosting tips you have in the comments i am all ears as it were posted by peter fröhlich at 1 57 am no comments email this blogthis share to x share to facebook share to pinterest tuesday may 1 2018 cobalt qube 2 raq 2 notes i ve had an old cobalt qube 2 in my possession since at least 2003 and i got my hands on an old cobalt raq 2 sometime in 2007 these are cute qute mips machines that used to work great as targets for my compilers and interpreters course sadly both boxes have been out of commission for a few years but i recently decided that i want to run them again the raq in particular in the process i noticed that a few important pieces of cobalt information are hard to find online these days so this post is mostly a collection of notes for myself first here are two basic shots of the raq 2 in pretty much the state i received it in over 10 years ago first note the lack of a cover for the power supply you ll need to be somewhat careful working in here if you re worried about a capacitor zapping you cobalt raq 2 front there is also a spot for a fan but apparently the power supply never gets hot enough because as you can see in the next shot that grate is actually covered by the cobalt logo cobalt raq 2 back the installed fan is incredibly tiny and in my raq 2 it doesn t sound particularly healthy anymore i have not double checked yet but supposedly cobalt used this sunon fan for the raq 2 sourcing an exact replacement fan has turned out to be difficult but i ve also found some ancient posts that claim that these machines don t really get hot enough to require a fan in the first place i am leaving mine in for now hoping that even if it fails it won t bring down the box with it next topic failed battery there s a cr2032 located on the main board next to the power supply sadly the thing has one of those dreaded sockets with an excessively tight retaining clip on top you re supposed to lift the clip and then slide out the battery but of course in the process of doing that the entire thing just ripped off the mainboard to add insult to injury a solder pad came off as well complete with the attached copper track of course socket and copper track yikes witness the complete destruction on the mainboard battery connector destroyed the lesson here is either that i am incapable of treating a piece of history with the required tenderness or that one should just leave good enough alone good enough well it turns out that the machine works perfectly fine with an empty battery better yet it works perfectly fine even with a ripped out battery so luckily i did not actually destroy the entire machine with this horrible mistake if i ever decide to give my qube 2 the same treatment i ll desolder the entire battery socket instead and replace it with a less insane one to be continued posted by peter fröhlich at 3 57 am 2 comments email this blogthis share to x share to facebook share to pinterest saturday january 27 2018 unlock luks remotely on ubuntu 16 04 lts i reinstalled my little server at work it had been running the same gentoo setup since 2008 but in december 2017 the gentoo folks finally managed to produce a convoluted enough update to completely hose the darn thing well not hose as in disaster of course i got all the data off safely and i could even leave it running over the holidays while i was away in germany but in preparation for the spring 2018 semester it was necessary to start from scratch as it were upset enough with gentoo i decided to go completely the other way and do a minimal ubuntu 16 04 lts install i also used this opportunity to finally add full disk luks encryption to my setup not that it makes much sense the server runs 24 7 so it s basically always decrypted but what the heck this is how you re supposed to set up your server right and instead of going for zfs or btrfs which is what i used on my new home machine i went retro one last time partition the disks into one small boot partition and one large data partition use mdadm to create a raid 1 boot and a raid 10 data array use cryptsetup to luks encrypt the huge data raid array use lvm to create swap root and various home volumes in the encrypted raid great but now i had a problem you see every now and then we actually have a power outage i know it s weird but since we re not the hospital we apparently don t get to have a redundant power grid i might not be around to reboot the machine manually but students want to submit their homework assignments and i don t like giving extensions so what to do enter the recent dropbear initramfs package this thing is supposed to integrate a tiny dropbear ssh server into the early root filesystem enabling remote unlocking of the encrypted raid array and it almost works first the easy parts apt install dropbear initramfs and ignore the error message mkdir p etc initramfs tools root ssh put your ssh keys into etc initramfs tools root ssh authorized_keys update initramfs u now when the machine boots up it ll still ask for a passphrase on the console but it will also start the dropbear ssh server in theory you can ssh in as root at that point and run the unlock script but that didn t work for me what did work however is to echo the passphrase directly to the fifo created by cryptsetup ssh root server echo n passphrase lib cryptsetup passfifo exit at this point the encrypted raid will come up and the boot process will continue just as if you had typed the passphrase at the console i am positive that they ll eventually fix the scripts but for now i am just happy that i was able to make it work note that it s convenient to run dropbear ssh and the regular openssh on different ports to avoid getting loads of useless warnings when connecting it s also just good sane practice if you want to keep the number of script kiddies trying to get into your server down to a minimum yes security through obscurity is bad but it s only really bad if it s your only approach happy remote booting posted by peter fröhlich at 4 11 pm no comments email this blogthis share to x share to
