DESCRIPTION
Editcap is a program that reads a saved capture file and writes some
or all of the packets in that capture file to another capture file.
Editcap knows how to read libpcap
capture files, including those of tcpdump. In addition, Editcap can
read capture files from snoop (including Shomiti) and atmsnoop,
LanAlyzer, uncompressed Sniffer, Microsoft Network Monitor,
AIX's iptrace, NetXray, Sniffer Pro, RADCOM's WAN/LAN
analyzer, Lucent/Ascend router debug output, HP-UX's nettl, and
the dump output from Toshiba's ISDN routers. There is no need to
tell Editcap what type of file you are reading; it will determine the
file type by itself. Editcap is also capable of reading any of these
file formats if they are compressed using gzip. Editcap recognizes
this directly from the file; the `.gz' extension is not required for
this purpose.
By default, it writes the capture file in libpcap format, and writes
all of the packets in the capture file to the output file. The -F
flag can be used to specify the format in which to write the capture
file; it can write the file in libpcap format (standard libpcap
format, a modified format used by some patched versions of libpcap,
or the format used by Red Hat Linux 6.1), snoop format, uncompressed
Sniffer format, Microsoft Network Monitor 1.x format, and the
format used by Windows-based versions of the Sniffer software.
A list of packet numbers can be specified on the command line; the
packets with those numbers will not be written to the capture file,
unless the -r flag is specified, in which case only those packets
will be written to the capture file.
If the -T flag, the encapsulation type of the output capture file
will be forced to the specified type, rather than being the type
appropriate to the encapsulation type of the input capture file. Note
that this merely forces the encapsulation type of the output file to be
the specified type; the packet headers of the packets will not be
translated from the encapsulation type of the input capture file to the
specified encapsulation type (for example, it will not translate an
Ethernet capture to an FDDI capture if an Ethernet capture is read and
'-T fddi' is specified).
OPTIONS
- -F
-
Sets the file format of the output capture file.
- -T
-
Sets the packet encapsulation type of the output capture file.
- -r
-
Causes the packets whose packet numbers are specified on the command
line to be written to the output capture file, and no other packets to
be written to the output capture file.
- -v
-
Causes editcap to print a number of messages while it's working.
- -h
-
Prints the version and options and exits.
