What kind of info can the System OP/ Admins can access when joined to their irc server? reddit / irc ---------------------------------------------------------------------- [deleted] · 2023-03-29 12:54 [deleted] ---------------------------------------------------------------------- nawcom · 2023-03-29 13:14 Nothing else that any other user can access, really. The information given via CTCP VERSION is completely defined by your irc client; you could have your client not respond to VERSION requests as it's not required. Whether the irc client you use allows you to define the VERSION response varies. The only way for an admin to know what OS you're running is if your irc client is programmed or configured to include that info in the VERSION response. In IRC you're making a very simplistic TCP connection to another computer. It's why you can use telnet to connect to an IRC server (non-SSL) and chat if you wanted to, if you understand the raw commands. So yeah there's nothing else really involved other than the IP address you're connecting from. Everything else is taken care of from the client end of things. ---------------------------------------------------------------------- trekkie1701c · 2023-03-29 13:40 > Nothing else that any other user can access, really. Sometimes they can see email addresses if you used them to register nicknames, depending on the services setup. Additionally, although some IRCds will allow channels to be 'hidden' and not show that you're on the channel (when doing a /whois), IRCOps can often still see these channels. But basically it boils down to "Anything you do on a server they can theoretically see"; there is, as you say, not really much else they can get. ---------------------------------------------------------------------- aftli · 2023-03-29 14:56 > It's why you can use telnet to connect to an IRC server (non-SSL) BTW the SSL equivalent of `telnet` is `openssl s_client -connect :`. ---------------------------------------------------------------------- skizzerz1 · 2023-03-29 15:00 Generally an oper can see: 1. All public info from /whois that all other users can see (obvious but I’m going for a mostly exhaustive list here) 2. Your IP address, even if you have a hidden host or a vhost (typically umode +x) 3. All channels you are currently joined to, even if you’re invisible (umode +i) and they don’t share those channels with you 4. If you are connecting with a TLS client certificate, the fingerprint for that certificate 5. The number of bytes of data you have sent and received during your current connection 6. How long you’ve been “idle” on your current connection (certain commands like sending a message reset idle time, other commands don’t, but the exact list varies by ircd) If the network has services and you have an account, they can generally look up all of those details as well. But you don’t need to be actively connected for them to do that, hence why I’m mentioning it here as an aside rather than making it part of the above list. ---------------------------------------------------------------------- [deleted] · 2023-03-29 15:24 [deleted] ---------------------------------------------------------------------- [deleted] · 2023-03-29 15:24 [deleted] ---------------------------------------------------------------------- tavaryn_t · 2023-03-29 15:45 We can see through your webcam, access your FurAffinity DMs and control your Lovense ---------------------------------------------------------------------- [deleted] · 2023-03-29 15:45 [deleted] ---------------------------------------------------------------------- skizzerz1 · 2023-03-29 18:41 No. They can only see things about your connection to the server and what you do on the server. Nothing about your client environment is visible to them unless you choose to share that information. ---------------------------------------------------------------------- SqualorTrawler · 2023-03-29 19:34 No. The best they can do is infer what you may be running based on the client you're running, if your IRC client is set up to respond honestly to a version request. You can try this on yourself. /CTCP VERSION A lot of clients can be configured to either not respond or respond with a custom string, but I don't think most people really pay much attention to this setting. https://blog.weechat.org/post/2009/10/05/IRC-CTCP-replies If I see they are running mIRC, my guess is they're running Windows, and chances are greater than average that they're oldtimers. Similarly if they are running Colloquy, I can infer they're on a Mac. Now, you can potentially configure certain Windows clients (not sure which) to respond that it is running a Mac client, so you can never be sure. You can simply guess. This is the equivalent of mucking around with your user agent string on your web browser. HW details, no, unless it is in the VERSION reply string. Even then, as I indicate above, people can fake that reply.
