You won't be able to capture packets, but you can read traces

that have already been captured to disk by other programs.

|

You can build or not build ethereal, tethereal, and editcap
|

with the appropriate --enable-XXX or --disable-XXX flags.

You can build or not build ethereal, tethereal, editcap, and

The default is to build everything. If GTK+ is not detected
|

on the system, then ethereal won't be built.

=head1 DESCRIPTION
|
||||
|
||||
B<Mergecap> is a program that reads two saved capture files and merges
|
||||
all of the packets in those capture files into a third capture
|
||||
file. B<Mergecap> knows how to read B<libpcap> capture files, including
|
||||
those of B<tcpdump>. In addition, B<Mergecap> can read capture files
|
||||
from B<snoop> (including B<Shomiti>) and B<atmsnoop>, B<LanAlyzer>,
|
||||
B<Sniffer> (compressed or uncompressed), Microsoft B<Network Monitor>,
|
||||
AIX's B<iptrace>, B<NetXray>, B<Sniffer Pro>, B<RADCOM>'s WAN/LAN
|
||||
analyzer, B<Lucent/Ascend> router debug output, HP-UX's B<nettl>, and
|
||||
the dump output from B<Toshiba's> ISDN routers. There is no need to
|
||||
tell B<Mergecap> what type of file you are reading; it will determine the
|
||||
file type by itself. B<Mergecap> is also capable of reading any of
|
||||
these file formats if they are compressed using gzip. B<Mergecap>
|
||||
recognizes this directly from the file; the '.gz' extension is not
|
||||
required for this purpose.
|
||||
|
||||
By default, it writes the capture file in B<libpcap> format, and writes
|
||||
all of the packets in both input capture files to the output file. The
|
||||
B<-F> flag can be used to specify the format in which to write the
|
||||
capture file; it can write the file in B<libpcap> format (standard
|
||||
B<libpcap> format, a modified format used by some patched versions of
|
||||
B<libpcap>, the format used by Red Hat Linux 6.1, or the format used by
|
||||
SuSE Linux 6.3), B<snoop> format, uncompressed B<Sniffer> format,
|
||||
Microsoft B<Network Monitor> 1.x format, and the format used by
|
||||
Windows-based versions of the B<Sniffer> software.
|
||||
|
||||
By default, the packets in the input files are merged in chronological
|
||||
order based on each frame's timestamp, unless the B<-a> flag is
|
||||
specified. B<Mergecap> assumes that frames within a single capture file
|
||||
are already stored in chronological order. When the B<-a> flag is
|
||||
specified, all the packets from the first input capture file are output,
|
||||
followed by all of the packets from the second input capture file.
|
||||
|
||||
If the B<-s> flag is used to specify a snapshot length, frames in the
|
||||
input file with more captured data than the specified snapshot length
|
||||
will have only the amount of data specified by the snapshot length
|
||||
written to the output file. This may be useful if the program that is
|
||||
to read the output file cannot handle packets larger than a certain size
|
||||
(for example, the versions of snoop in Solaris 2.5.1 and Solaris 2.6
|
||||
appear to reject Ethernet frames larger than the standard Ethernet MTU,
|
||||
making them incapable of handling gigabit Ethernet captures if jumbo
|
||||
frames were used).
|
||||
|
||||
If the B<-T> flag is used to specify an encapsulation type, 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 'B<-T
|
||||
fddi>' is specified).

||||
=head1 OPTIONS
|
||||
|
||||
=over 4
|
||||
|
||||
=item -F
|
||||
|
||||
Sets the file format of the output capture file.
|
||||
|
||||
=item -T
|
||||
|
||||
Sets the packet encapsulation type of the output capture file.
|
||||
|
||||
=item -a
|
||||
|
||||
Causes the frame timestamps to be ignored, writing all packets from the
|
||||
first input file followed by all packets from the second input file. By
|
||||
default, when B<-a> is not specified, the contents of the input files
|
||||
are merged in chronological order based on each frame's timestamp.
|
||||
Note: when merging, B<mergecap> assumes that packets within a capture
|
||||
file are already in chronological order.
|
||||
|
||||
=item -v
|
||||
|
||||
Causes B<mergecap> to print a number of messages while it's working.
|
||||
|
||||
=item -s
|
||||
|
||||
Sets the snapshot length to use when writing the data.
|
||||
|
||||
=item -h
|
||||
|
||||
Prints the version and options and exits.
