9 tcpbug [-cx] [-btT] local-port remote-host remote-port
10
12 tcpbug forwards a TCP/IP connection to port local-port on the local
13 machine to the port remote-port on remote-host while spying on the con‐
14 nection and writing all data passing through to standard output. All
15 data coming from the client is printed with a greater than sign (>)
16 first on each line, and all data coming from the server is printed with
17 a less than sign (<) first on each line. Any byte offsets and time-
18 stamps are printed before the greater than or less than sign, and are
19 separated from each other by a colon (:).
20
22 -b Print the offset of the first byte in the stream for each line.
23 -c Display bytes as individual characters. Printable characters
25 are displayed directly, some control characters appear as C-lan‐
26 guage escapes (\n, \r, \t et.c), while others appear as 3-digit
27 octal numbers. This should be similar to the -c switch of
28 od(1).
29 -t Print the time at which the data was received for each line.
31 The time is the number of seconds and microseconds, separated by
32 a decimal point (.), since 00:00 UTC, January 1, 1970, as
33 reported by gettimeofday().
34 -T Print the time at which the data was received for each line.
36 The time is the number of seconds and microseconds, separated by
37 a decimal point (.), since the connections were established.
38 -x Display each byte as a two digit hexadecimal number.
40
42 tcpconnect(1), tcplisten(1), od(1).

45 The names of the options are not yet finalized, and may change at a
46 future release.
