Tracing and Logging Utilities

netfmt

Chapter 7182

Use this option to specify the binary file containing the

log or trace data. This is the name of the .TRC0 file that

was specified when nettl was run the first time with

the -traceon and -file options. By default, data is

read from standard input.

-v Enables “verbose” mode, but also gives the full data

output for each packet header (see Examples section

below).

-N Enables “Nice” formatting of output. Only packet

headers and the first few lines of the main data output

are displayed. Only the data length is provided in

addition to the packet header to make the output easier

to read (see Examples section below).

-1 (one) Enables “terse” (short) mode formatting of each

traced packet on a single line. Output lines will be

more than 80 characters long if the -L and/or -T

options are used (see Examples section below).

-l (small letter “l”) Use this option when you send

formatted trace data to a line printer to turn off inverse

video highlighting of all trace fields.

Examples

To format the file /tmp/tracex25.TRC0 in “verbose” mode (packet

headers plus full data output for each header) with no filtering:

/etc/netfmt -v -f /tmp/tracex25.TRC0 | more

The output will resemble the following:

vvvvvvvvvvvvvvvvvvvvvvLAN/X.25NETWORKINGvvvvvvvvvvvvvvvvvvvvvvvvv
