18 Redir redirects tcp connections coming in to a local port to a
19 specified address/port combination.
20 It may be run either from inetd or as a standalone daemon.
22 Depending on how redir was compiled, not all options may be
23 available.
24
26 --lport
27 Specifies port to listen for connections on (when not
28 running from inetd)
29 --laddr
31 IP address to bind to when listening for connections
32 (when not running from inetd)
33 --cport
35 Specifies port to connect to.
36 --caddr
38 Specifies remote host to connect to. (localhost if omit‐
39 ted)
40 --inetd
42 Run as a process started from inetd, with the connection
43 passed as stdin and stdout on startup.
44 --debug
46 Write debug output to stderr or syslog.
47 --name Specify program name to be used for TCP wrapper checks
49 and syslog logging.
50 --timeout
52 Timeout and close the connection after n seconds of
53 inactivity.
54 --syslog
56 Log information to syslog.
57 --bind_addr
59 Forces redir to pick a specific address/interface to
60 bind to when it listens for incoming connections.
61 --ftp When using redir for an FTP server, this will cause
63 redir to also redirect ftp connections. Type should be
64 specified as either "port", "pasv", or "both", to spec‐
65 ify what type of FTP connection to handle. Note that
66 --transproxy often makes one or the other (generally
67 port) undesirable.
68 --transproxy
70 On a linux system with transparent proxying enabled,
71 causes redir to make connections appear as if they had
72 come from their true origin. (see
73 /usr/share/doc/redir-2.2.1/transproxy.txt)
74 --connect
76 Redirects connections through an HTTP proxy which sup‐
77 ports the CONNECT command. Specify the address and port
78 of the proxy using --caddr and --cport. --connect
79 requires the hostname and port which the HTTP proxy will
80 be asked to connect to.
81 --bufsize n
83 Set the bufsize (defaut 4096) in bytes. Can be used com‐
84 bined with --max_bandwidth or --random_wait to simulate
85 a slow connection.
86 --max_bandwidth n
88 Reduce the bandwidth to be no more than n bits/sec. The
89 algorithme is basic, the goal is to simulate a slow con‐
90 nection, so there is no pic acceptance.
91 --random_wait n
93 Wait between 0 and 2 x n milliseconds before each
94 "packet". A "packet" is a bloc of data read in one time
95 by redir. A "packet" size is always less than the buf‐
96 size (see also --bufsize).
97 --wait_in_out n
99 Apply --max_bandwidth and --random_wait for input if
100 n=1, output if n=2 and both if n=3.
