Does citadel have a 64-bit ARM image?

Citadel will run just fine on 64-bit ARM but you have to build it yourself using Easy Install.

I assume you're talking about the container version, which we currently build using a cross compiler (and occasionally test on a real Pi). The cross compiler crashes when we try 64-bit ARM and I don't know why. Hopefully this will get worked out in some future version of the development kit and we'll add ARM 64 to the build.

Funny you mention that. When you asked for a preview I attempted to set one up here on our production system. It didn't work right, so I said ok, let's finally upgrade my system to 64-bit which I've been putting off for a few years now. That was going to take too much time once I kicked off the migration.
So there went my Saturday with nothing to show for it :)

[Reply] [ReplyQuoted] [Headers] [Print]

I noticed that large quantities of spam emails were going though port 587 of my Citadel server.  I have the IP address of the spammer.  How do I find out which of my users (if any) this IP address corresponds to.  I have a log file in the database (under /usr/local/citadel/data), but it is spectacularly unhelpful.  In general, how can I determine how many emails each particular user has sent and received?  Is there a way to limit the number of emails that each user can send (say, to 500)?  Any ideas about how to prevent this from happening again in the future?

If it came through port 587 then it's an authenticated user, which it seems you have already figured out.

The "log files" in a database refer to database journaling, not system logs, so that's definitely not the place to look.

Unfortunately there is no setting in Citadel which would limit the number of emails that a user can send. They're either allowed or not allowed. You could look at the userlist though, and find a user with a particularly outrageously high message count. That's problably the one. Best practice, however, would dictate that you have all your users change their passwords and make sure they're good passwords.

If you really want to rate-limit incoming SMTP connections from a single IP address, you can do that from the operating system's own firewall. For example, if you are running on Linux you can rate-limit the port using iptables.
Here's an example I found on the internet:

i've still got the issue i had with the user and havent been able to try the fix you told me yet due to updating. i backed it up so i could just revert if things don't go well.. and i've not been able to successfully update yet. it seems to go ok but when it goes to "connecting to citadel server" the green [**----------------] loading bar disappears and it just sits there while the website gives me a 503 error. not quite sure what i should check.

Thank you for the information about rate limiting posts using IP tables.

None of my users has more than a handful of messages shown on the administrator's "Edit user account" page.  Also, I have now unchecked the "Permission to send Internet mail" box for all of my users, but apparently emails are still being sent--at least, that is how I am interpreting what I am seeing in my Linux syslog file (repeated every 2 seconds):

Nov  5 05:07:45 superman citserver[527]: citserver[527]: context: session (SMTP-MSA) started from ****removed**** (****removed****) uid=-1
Nov  5 05:07:45 superman citserver[527]: context: session (SMTP-MSA) started from ****removed**** (****removed****) uid=-1
Nov  5 05:07:49 superman citserver[527]: citserver[527]: context: [ 80]SRV[SMTP-MSA] Session ended.
Nov  5 05:07:49 superman citserver[527]: context: [ 80]SRV[SMTP-MSA] Session ended.
Nov  5 05:07:49 superman citserver[527]: citserver[527]: context: [ 81]SRV[SMTP-MSA] Session ended.
Nov  5 05:07:49 superman citserver[527]: context: [ 81]SRV[SMTP-MSA] Session ended.


The lights on the server and router were also flashing rapidly, which indicate a large amount of traffic.  Is it possible that I am misinterpreting what I am seeing in the syslog file?   Could a user's computer only be making a connection every 2 seconds but not sending anything?  I am not seeing any outgoing emails in my Linux mail.log log file, only incoming ones, so I am not sure whether outgoing emails are actually being sent.  Enabling journaling under the "Indexing/Journaling" and checking the boxes "Enable full text index" and "Perform journaling of email messages" does not seem to do anything other than adding some entries to the syslog file, but I may just not know where to look for whatever journal files are produced by those settings.

Also, I could not find any useful information about the difference between a "local user" and a "network user".  Does it have anything to do with the ability of a user to send or receive email to the WAN, verses limiting it to the LAN?

it took a while for me to update but i finally figured out how to rebuild the database and all that. so its updated now but when i go into the console with that command it allows me to login and shows me lobby messages, i get to the lobby prompt but it freezes, not allowing any input. it doesn't seem to be taking up any cpu or anything. looking into that issue now, but its running pretty well with the updates and all. no issues and everything's intact after rebuilding the database. going to dig around for logs and see why it would just hang up without doing or saying anything.

Turns out it didn't work because there was a legit bug that only manifested on 32-bit Linux (which is what Uncensored is still running).

I believe we now have a nightly build running at https://uncensored.citadel.org:4443

No promises here, of course.  It's the current state of the code and maybe it works.  You should be able to log in, and you should be able to view Forums and Mail.  It won't update your last-read pointer in each room, so it's probably not usable as your daily driver yet.   But it'll give you an idea what the new framework will look like.

Oh, and for anyone trying out the nightly builds of WebCit-NG [ https://uncensored.citadel.org:4443 ]
Here are some guidelines:

1. DO NOT REPORT BUGS. It's unfinished. We know it has bugs.
2. Don't worry about breaking it. You can't hurt the site by playing around with the demo. Worst that happens is you break the demo but the production site keeps running, and I don't care about that.
3. Don't bother trying to see if you can subvert the site's security through some half-completed section of the web interface. That can't be done because all access controls still live inside the Citadel Server, which is hardened and mature.

That having been said ... enjoy the preview of what has been built so far.
It is very much "under construction" but you should be able to see where we're going with it. The style is very modern, the underpinnings are totally REST and DAV to allow greater interoperability with third-party software, and the UI approach is to organize the system as a set of applications (mail, forums, calendar, etc.) instead of as an overgrown BBS that can also do other things.

For web design geeks: everything is HTML5+CSS+DOM+XHR, straight to the browser, no third-party frameworks. We tried a couple of different frameworks (Bootstrap and W3CSS) and they made things look nice out-of-the-box, but ended up being restrictive when we tried to do anything fancy. Modern browser features like Grid and Flexbox make this stuff easy.

Share And Enjoy!
