- ---------------------------------------------------------------------------
- PROGRAM
- lookupdns
- FILES
- lookupdns.c
- res.c
- USAGE
- lookupdns <hostname1> [<hostname2>] ...
- DESCRIPTION
- This program performs asynchronous DNS host name resolution and reports
- IP address for each <hostname> specified as a command line argument.
- One ST thread is created for each host name. All threads do host name
- resolution concurrently.
- ---------------------------------------------------------------------------
- PROGRAM
- proxy
- FILES
- proxy.c
- USAGE
- proxy -l <local_addr> -r <remote_addr> [-p <num_processes>] [-S]
- -l <local_addr> bind to local address specified as [<host>]:<port>
- -r <remote_addr> connect to remote address specified as <host>:<port>
- -p <num_processes> create specified number of processes
- -S serialize accept() calls from different processes
- on the same listening socket (if needed).
- DESCRIPTION
- This program acts as a generic gateway. It listens for connections to a
- local address. Upon accepting a client connection, it connects to the
- specified remote address and then just pumps the data through without any
- modification.
- ---------------------------------------------------------------------------
- PROGRAM
- server
- FILES
- server.c
- error.c
- USAGE
- server -l <log_directory> [<options>]
- -l <log_directory> open all log files in specified directory.
- Possible options:
- -b <host>:<port> bind to specified address (multiple addresses
- are permitted)
- -p <num_processes> create specified number of processes
- -t <min_thr>:<max_thr> specify thread limits per listening socket
- across all processes
- -u <user> change server's user id to specified value
- -q <backlog> set max length of pending connections queue
- -a enable access logging
- -i run in interactive mode (useful for debugging)
- -S serialize accept() calls from different processes
- on the same listening socket (if needed).
- DESCRIPTION
- This program is a general server example. It accepts a client connection
- and outputs a short HTML page. It can be easily adapted to provide
- other services.
