Depending on how redir was compiled, not all options may be available.
.SH OPTIONS
.TP
-.B \--lport
+.B \-\-lport
Specifies port to listen for connections on (when not running from inetd)
.TP
-.B \--laddr
+.B \-\-laddr
IP address to bind to when listening for connections (when not
running from inetd)
.TP
-.B \--cport
+.B \-\-cport
Specifies port to connect to.
.TP
-.B \--caddr
+.B \-\-caddr
Specifies remote host to connect to. (localhost if omitted)
.TP
-.B \--inetd
+.B \-\-inetd
Run as a process started from inetd, with the connection passed as stdin
and stdout on startup.
.TP
-.B \--debug
+.B \-\-debug
Write debug output to stderr or syslog.
.TP
-.B \--name
+.B \-\-name
Specify program name to be used for TCP wrapper checks and syslog logging.
.TP
-.B --timeout
+.B \-\-timeout
Timeout and close the connection after n seconds of inactivity.
.TP
-.B \--syslog
+.B \-\-syslog
Log information to syslog.
.TP
-.B \--bind_addr
+.B \-\-bind_addr
Forces redir to pick a specific address/interface to bind to when it listens
for incoming connections.
.TP
-.B \--ftp
+.B \-\-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)
+Note that \-\-transproxy often makes one or the other (generally port)
undesirable.
.TP
-.B \--transproxy
+.B \-\-transproxy
On a linux system with transparent proxying enabled, causes redir to
make connections appear as if they had come from their true origin.
(see /usr/share/doc/redir/transproxy.txt)
.TP
-.B \--connect
+.B \-\-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
+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.
.TP
-.B \--bufsize n
+.B \-\-bufsize n
Set the bufsize (defaut 4096) in bytes. Can be used combined with
---max_bandwidth or --random_wait to simulate a slow connection.
+\-\-max_bandwidth or \-\-random_wait to simulate a slow connection.
.TP
-.B \--max_bandwidth n
+.B \-\-max_bandwidth 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.
.TP
-.B \--random_wait n
+.B \-\-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).

-.B \--wait_in_out n
-Apply --max_bandwidth and --random_wait for input if n=1, output if n=2 and

+Apply \-\-max_bandwidth and \-\-random_wait for input if n=1, output if n=2 and

# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.
# Line up the first '|' above the ':' following the base package name, and
# the '|' on the right side marks the last column you can put a character in.
# You must make exactly 11 lines for the formatting to be correct. It's also
# customary to leave one space after the ':' except on otherwise blank lines.
