Redir redirects tcp connections coming in to a local port to a specified
address/port combination.
It may be run either from inetd or as a standalone daemon.
Depending on how redir was compiled, not all options may be available.
- --lport
- Specifies port to listen for connections on (when not running from
inetd)
- --laddr
- IP address to bind to when listening for connections (when not running
from inetd)
- --cport
- Specifies port to connect to.
- --caddr
- Specifies remote host to connect to. (localhost if omitted)
- --inetd
- Run as a process started from inetd, with the connection passed as stdin
and stdout on startup.
- --debug
- Write debug output to stderr or syslog.
- --name
- Specify program name to be used for TCP wrapper checks and syslog
logging.
- --timeout
- Timeout and close the connection after n seconds on inactivity.
- --syslog
- Log information to syslog.
- --bind_addr
- Forces redir to pick a specific address/interface to bind to when it
listens for incoming connections.
- --ftp
- When using redir for an FTP server, this will cause redir to also redirect
ftp connections. Type should be specified as either "port",
"pasv", or "both", to specify what type of FTP
connection to handle. Note that --transproxy often makes one or the other
(generally port) undesirable.
- --transproxy
- On a linux system with transparany proxying enables, causes redir to make
connections appear as if they had come from their true origin. (see
transproxy.txt in the source archive)
- --connect
- Redirects connections through an HTTP proxy which supports the CONNECT
command. Specify the address and port of the proxy using --caddr and
--cport. --connect requires the hostname and port which the HTTP proxy
will be asked to connect to.
- --bufsize n
- Set the bufsize (defaut 4096) in bytes. Can be used combined with
--maxbandwidth or --random_wait to simulate a slow connection.
- --maxbandwidth n
- Reduce the bandwidth to be no more than n bits/sec. The algorithme is
basic, the goal is to simulate a slow connection, so there is no pic
acceptance.
- --random_wait n
- Wait between 0 and 2 x n milliseconds before each "packet". A
"packet" is a bloc of data read in one time by redir. A
"packet" size is always less than the bufsize (see also
--bufsize).
- --wait_in_out n
- Apply --maxbandwidth and --random_wait for input if n=1, output if n=2 and
both if n=3.
