|
|
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.

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.
