What's The World Record For Maximum Simultaneous Connections?

Posted by Cliff on from the my-server-can-handle-more-sockets-than-yours dept.

epiphani asks: "Recently a DALnet server, twisted.dal.net broke an IRC record for maximum simultanious connections at 33,829. As part of the DALnet coding team (the creators of Bahamut, DALnet's ircd), I am curious if that is a world record for open sockets in a production environment. Would anyone know if this is the case? Also, the machine is an Athlon 900 running Debian. I cant say I am a Linux fan, but the arguement regarding Linux vs *BSD in socket handling is quite moot at this point as they appear to perform at roughly the same level." Man, that's a lot of open sockets. I don't know if Ripley's tracks this kind of information, but it would be interesting to know if this number beats anything you folks have seen.

    That's SURE to generate more than 34000 hits at once.

    For the humour-impaired: this is a joke.

    65,535 simultaneous open sockets.

    I think there is a world market for maybe five personal web logs.

    ARP doesn't use UDP. ARP operates between layer 2 (data link layer, such as ethernet) and layer 3 (network layer, in this case IP.) UDP is a layer 4 (transport) protocol.

    I did that once. The sysadmin starred my password. At that time we had to dial into the modem server and telnet from there to get a shell prompt, so I wrote a eudora script to get me to a shell prompt and then download my mail from there. Seems that I had a little bug in the script that caused it to keep attempting to log into the mail server. I forget how many times I ended up being logged in, but I do remember the sysadmin showing me the printout of the log and yelling "Do you know what this is?"
