This little program opens as many sockets with a remote host as can be supported by both. It catches ^C and kill commands to shut down cleanly by closing all open connections before exiting. Often, a remote workstation can be brought to its knees by saturating its process table via multiple invocations of sendmail. That's why port 25 (the sendmail port) is the default. If the target's process table (set when the target kernel was created) is filled, users will be unable to execute any shell commands. Many MUDs also crash when the number of sockets they have open exceeds a certain number. This program will put stress on MUDs by testing their limits. If a limit is reached, the MUD will either crash or will refuse to let new users log in. * The program is incomplete, in that it doesn't check for socket timeouts and subsequently reuse timed out sockets. That means the program can only keep a remote host / mud locked up until it exhausts its own available new sockets, or until it has...

That means the program can only keep a remote host / mud locked up until it exhausts its own available new sockets, or until it has reached MAX_DESCRIPTORS remote connections as set by the #define statement. * If the local machine starts issuing error messages, then the program has failed to saturate the remote host and has instead reached the limits of the local machine. Use ^C or the kill command to terminate it. If you are knowledgable about rebuilding kernels and have access to the root account, you can build a special kernel that will allow you to reach a much larger number of open sockets.
