NAME¶
rawtmp - display wtmp entries in raw form.
SYNOPSIS¶
rawtmp [
-da] [
-w wtmp|
-] [
-X[3|4]d]
[
-s start] [
-e end] [
-b H:M:S]
[
--help] [
--version]
DESCRIPTION¶
Rawtmp is a utility to dump the raw data in a wtmp or utmp file to the
screen for viewing. It may be useful to anyone who wishes to divine the nature
of the data stored in the wtmp or utmp files. It may also be useful to extract
special wtmp entries that are not documented anywhere (like those netdate puts
in the wtmp file).
If on a logout, when the username is encoded in the ut_user field by replacing
the first character of the username with a null, rawtmp will print the
contents of the user field with a leading dot '.' to denote the null
character. Only
agetty and
tacacs control software are currently
known to use this logging method.
OPTIONS¶
Rawtmp understands the following command line switches:
- --help
- Outputs a verbose usage listing.
- --version
- Displays the version of rawtmp.
- -w wtmp
- Select a different input file instead of the default
(/var/log/wtmp).
- -X[3]
- Read a wtmp file maintained by versions 3.3 or 3.4 Tacacs
terminal server access control software.
- -X4
- Read a wtmp file maintained by version 4.0 of Tacacs
terminal server access control software.
- -d
- Output the time in MMM DD HH:MM:SS format instead of raw
time for a more human readable form (and to actually know what day you're
looking at!).
- -a
- Print the contents of the ut_addr field (in quad-dotted
notation) instead of using the ut_host field. Note: ut_addr is almost
never used and more than likely contains garbage information.
- -b
hours[:minutes[:seconds]]
- Consider only those utmp entries that fall within the last
few hours/minutes/seconds from the current time, disregarding the
rest.
- -s start
- Selects the starting date of the report, in mm/dd/yy
format.
- -e end
- Selects the ending date of the report, in mm/dd/yy
format.
FILES¶
/var/log/wtmp login database.
