"Bogus userid" error if identd is turned off and nothing to slow it down #1

Closed hiddn closed 8 years ago

hiddn commented 8 years ago

The following all happens quickly without any delay, and without any time for the client to send any nick/user data:

$ telnet 127.0.0.1 6666 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. NOTICE AUTH :* Checking Ident NOTICE AUTH :* No ident response ERROR :Closing Link: by hidden.undernet.org (USER: Bogus userid.) Connection closed by foreign host.

Then, after typing the following command, it connects without a problem:

$ sudo iptables -I INPUT -i lo -m tcp -p tcp --dport 113 -j DROP $ telnet 127.0.0.1 6666 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. NOTICE AUTH :*\ Checking Ident [...]

Connection works fine if identd is working on the client, so it just doesn't work when it gets a quick connection refused on port 113.
