@prologic@twtxt.net What? I compiled, updated, and restarted. If you check what my pod reports, it gives that 7a… SHA. I don’t know what that other screenshot is showing but it seems to be out of date. That was the SHA I was running before this update.

@prologic@twtxt.net Here’s a log entry:

Aug 27 15:59:43 buc yarnd[1200580]: [yarnd] 2024/08/27 15:59:43 (IP_REDACTED) "GET /external?nick=lovetocode999&uri=https://URL_REDACTED HTTP/1.1" 200 35442 14.554763ms

HTTP 200 status, not 404.

@prologic@twtxt.net This does not seem to fix the problem for me, or I’ve done something wrong. I did the following:

1. Pull the latest version from git (I have commit 7ad848, same as on twtxt.net I believe).
   
2. make build and make install
   
3. Restart yarnd
   
4. Refresh cache in Poderator Settings
   

Yet I still see these bogus /external things on my pod when I hit URLs like the one I sent you recently. When I hit such a URL with curl I think it’s giving an error? But in a web browser, the (buggy) response is the same as it was before I updated.

So, this problem is not fixed for me.

@prologic@twtxt.net Aha, now it gives an error. OK I’m updating to this to see if it fixes the issue on my pod! Thank you.

@prologic@twtxt.net I believe you are not seeing the problem I am describing.

Hit this URL in your web browser:

https://twtxt.net/external?nick=lovetocode999&uri=https://socialmphl.com/story19510368/doujin

That’s your pod. I assume you don’t have a user named lovetocode999 on your pod. Yet that URL returns HTTP status 200, and generates HTML, complete with a link to https://socialmphl.com/story19510368/doujin, which is not a twtxt feed (that’s where the twtxt.txt link goes if you click it). That link could be to anything, including porn, criminal stuff, etc, and it will appear to be coming from your twtxt.net domain.

What I am saying is that this is a bug. If there is no user lovetocode999 on the pod, hitting this URL should not return HTTP 200 status, and it should definitely not be generating valid HTML with links in it.

Edit: Oops, I misunderstood the purpose of this /external endpoint. Still, since the uri is not a yarn pod, let alone one with a user named lovetocode999 on it, I stand by the belief that URLs like this should be be generating valid HTML with links to unknown sites. Shouldn’t it be possible to construct a valid target URL from the nick and uri instead of using the pod’s /external endpoint?

@prologic@twtxt.net @bender@twtxt.net I partially agree with bender on this one I think. The way this person is abusing the /external endpoint on my pod seems to be to generate legitimate-looking HTML content for external sites, using a username that does not exist on my pod. One “semantically correct” thing to do would be to error out if that username does not exist on the pod. It’s not unlike having a mail server configured as an open relay at this point.

It would also be very helpful to give the pod administrator control over what’s being fetched this way. I don’t want people using my pod to redirect porn sites or whatever. If I could have something as simple as the ability to blacklist URLs that’d already help.

@lyse@lyse.isobeef.org Interesting. The yarnd --help currently says (for me):

  -R, --open-registrations            whether or not to have open user registgration

meaning it doesn’t give the default setting or warn you that you need to use -R=false and not -R false. It also leaves unclear whether --open-registrations false would work or if you need to do --open-registrations=false. It’s also unclear whether the setting change in the user interface is overridden by the command line arguments, overrides the command line arguments, is persisted across restarts.

Maybe all this is worth posting an issue for additional documentation on the git repo if there isn’t one already.

“registgration” is misspelled that way in the help by the way.

@lyse@lyse.isobeef.org in Australia, take everything you have learned, and do the opposite. After all, it is the land down under! :-D

@aelaraji@aelaraji.com didn’t know there was a place to fix them; in here we toss them. Wish it was cheap to ship stuff. I have a couple of decent monitors in the garage that will soon take a trip to the curve…

@lyse@lyse.isobeef.org ugh, how come didn’t this occurred to me…! Oh well, I am good now, but noted. Thanks!

@prologic@twtxt.net salt’em to keep them viable longer. Salt’em! :-D

@yarn_police@twtxt.net yay! Law and order on the watch!

@movq@www.uninformativ.de Yeah, haven’t seeing the @yarn_police@twtxt.net for a while. I often wonder if we are, finally, crime free. :-D

@lyse@lyse.isobeef.org Ha, sweet thanks for this! For some reason I thought you had to do this with an environmental variable or command-line option and I didn’t think to check the settings. 🤦‍♂

@prologic@twtxt.net Ah nice, thank you! Do you think this fix is ready for me to test it or do you think I should wait til you poke at it?

@movq@www.uninformativ.de woot! Yes! Perfect now. Hitting reply opens it with insert, and prompt at the end of the first line. Just as I wanted it. Thank you much!

@lyse@lyse.isobeef.org welcome! :-) I am doing my best to get more acquaintance with vi/vim. I think nano has spoiled me too much. LOL.

@movq@www.uninformativ.de hmm, I am already using au BufNewFile,BufRead jenny-posting.eml setl completefunc=jenny#CompleteMentions fo-=t wrap, from jenny. How would I go to incorporate that there?

@lyse@lyse.isobeef.org “good, good, and fascinating indeed” – says Quark, all while eating an overflowing toast with butter, and blackberry jam. :-D

@aelaraji@aelaraji.com power outages happen here almost every single time strong storms pass by, I know the feeling mate. It truly sucks.

@movq@www.uninformativ.de hmm, I guess I could do that too. I have startinsert set on my .vimrc, so I will either have to take it out, or exit insert, $, then insert again. I think the way you do it would be the way to go.

I tried setting VISUAL to be something like vim -c 'star!', which does the same thing, but no dice. :-/

@movq@www.uninformativ.de, maybe you can help me with this. I want to place the vim cursor at the end of the first line on replies, and forks. I have tried adding to this to jenny’s configuration:

"editor": "vim \"+normal $\"",

But that doesn’t work. How would you go about it?

@prologic@twtxt.net sounds fair. Let’s see how it works for @abucci@anthony.buc.ci. Speedy fix, that’s awesome! :-)

@bender@twtxt.net and I saw some conspiracy theory that he knew he was going to be arrested. He was working with French intelligence on a plea deal to defect. And now Russia is freaking out that Ukraine allies can have war comms access.

Yikes! If only they had salty.im!

There is a bug in yarnd that’s been around for awhile and is still present in the current version I’m running that lets a person hit a constructed URL like

YOUR_POD/external?nick=lovetocode999&uri=https://socialmphl.com/story19510368/doujin

and see a legitimate-looking page on YOUR_POD, with an HTTP code 200 (success). From that fake page you can even follow an external feed. Try it yourself, replacing “YOUR_POD” with the URL of any yarnd pod you know. Try following the feed.

I think URLs like this should return errors. They should not render HTML, nor produce legitimate-looking pages. This mechanism is ripe for DDoS attacks. My pod gets roughly 70,000 hits per day to URLs like this. Many are porn or other types of content I do not want. At this point, if it’s not fixed soon I am going to have to shut down my pod. @prologic@twtxt.net please have a look.

@mckinley@twtxt.net He’s signed up three times now even though I keep deleting the account, which is enough for me to permaban this person. I don’t technically want open registrations on my pod but up till now I’ve been too lazy to figure out how to turn them off and actually do that, and there hasn’t been a pressing need. I may have to now.

@movq@www.uninformativ.de is there a way to purge twtxts from a feed I no longer follow?

@movq@www.uninformativ.de, using the branch on topic right now, it works perfect. The only thing I found was that I had to quit neomutt, and re-open, to see the perfect thread. Other than that, I love it!

@bender@twtxt.net hmm, I wonder if these are simply twtxts auto created from an ActivityPub feed. Ah, crap, they are. LOL.

@support@anthony.buc.ci No. Try this again and I nuke your IP.

@prologic@twtxt.net Yes, fetching the twt by hash from some service could be a good alternative, in case the twt I have does not @-mention the source. (Besides yarnd, maybe this should be part of the registry API? I don’t see fetch-by-hash in the registry API docs.)

@movq@www.uninformativ.de confirming that the issue isn’t present when using alacrity. Wow.

@falsifian@www.falsifian.org the reason behind his sporadic disappearances is that he runs things from a Raspberry Pi, at home, I believe. That impacts reliability, I figure.

@movq@www.uninformativ.de my fault! Err, I meant to say, @bender@twtxt.net’s! LOL.

@lyse@lyse.isobeef.org ah, if only you were to finally clean up that code, and make that client widely available…! One can only dream, right? :-)

@lyse@lyse.isobeef.org I mean, dinosaurs “evolved” by getting wiped, right? :-D

@movq@www.uninformativ.de you said you liked seeing the hash (which is a fair choice!). All I am asking is for a reconsideration as a user configurable feature. ;-) It looks redundant, in my opinion.

@bender@twtxt.net it sure breaks the index formatting.

@aelaraji@aelaraji.com, this one, @movq@www.uninformativ.de, is slightly breaking my neomutt index. Will post screenshot from @bender@twtxt.net’s account.

@movq@www.uninformativ.de, that would be a nice addition. :-) I would also love the ability to hide/not show the hash when reading twtxts (after all, that’s on the header on each “email”). Could that be added as a user configurable toggle?

@movq@www.uninformativ.de I don’t know if I’d want to discard the twts. I think what I’m looking for is a command “jenny -g https://host.org/twtxt.txt” to fetch just that one feed, even if it’s not in my follow list. I could wrap that in a shell script so that when I see a twt in reply to a feed I don’t follow, I can just tap a key and the feed will get added to my maildir. I guess the script would look for a mention at the start of a selected twt and call jenny -g on the feed.

@movq@www.uninformativ.de Is there a good way to get jenny to do a one-off fetch of a feed, for when you want to fill in missing parts of a thread? I just added @slashdot@feeds.twtxt.net to my private follow file just because @prologic@twtxt.net keeps responding to the feed :-P and I want to know what he’s commenting on even though I don’t want to see every new slashdot twt.

@bender@twtxt.net Based on my experience so far, as a user, I would be upset if my client dropped someone from my follower list, i.e. stopped fetching their feed, without me asking for that to happen.

@bender@twtxt.net I’m not a yarnd user, but automatically unfollowing on 404 doesn’t seem right. Besides @lyse@lyse.isobeef.org’s example, I could imagine just accidentally renaming my own twtxt file, or forgetting to push it when I point my DNS to a new web server. I’d rather not lose all my yarnd followers in a situation like that (and hopefully they feel the same).

@prologic@twtxt.net @bender@twtxt.net Exponential backoff? Seems like the right thing to do when a server isn’t accepting your connections at all, and might also be a reasonable compromise if you consider 404 to be a temporary failure.
