pmremlog

Syntax
pmremlog -v  
pmremlog -p pmlog|pmreplay|pmlogtxtsearch [-o <outfile>] 
pmremlog [-h <host>] [-b] [-c] -- <program args>
Description

The pmremlog command provides a wrapper for the pmlog and pmreplay utilities to access the event (audit) and keystroke (I/O) logs on any server in the policy group. Anyone in the pmlog group can run this utility on the primary policy server.

Note that pmlogtxtsearch is a command located in /opt/quest/libexec.

Options

pmremlog has the following options.

Table 39: Options: pmremlog
Option Description

-b

Disables interactive input and uses batch mode.

-c

Displays output in CSV, rather than human-readable format.

-h <host>

Specifies a host in the policy server group to access.

-o <outfile>

Saves the pmlog output to a file.

-p

Specifies program to run:

  • pmlog

  • pmreplay

  • pmlogtxtsearch

-v

Displays the Safeguard for Sudo version number.

Examples

To view the audit log on the primary policy server, enter:

pmremlog -p pmlog -- -f /var/opt/quest/qpm4u/pmevents.db

To view the audit events for user fred on secondary policy server host1, save the pmlog output to a file, and display the result of the pmremlog command in CSV format, enter:

pmremlog -p pmlog -c -o /tmp/events.txt -h host1 -- --user fred

To view the stdout from keystroke log id_host1_x3jfuy, on secondary policy server host1, enter:

pmremlog -p pmreplay -h host1 -- -o -f /var/opt/quest/qpm4u/iologs/id_host1_x3jfuy

To retrieve the contents of keystroke log id_host1_x3jfuy, from secondary policy server host1, formatted for the pmreplay GUI, save the output to a temporary file, and display the result of the pmremlog command in CSV format, enter:

pmremlog -p pmreplay -h host1 -c -o /tmp/replay -- -zz -f /var/opt/quest/qpm4u/iologs/id_host1_x3jfuy

pmreplay

Syntax
pmreplay -V 
pmreplay -[t|s|i] -[Th] <filename> 
pmreplay -[e][I][o] -[EhKTv] <filename> 
Description

Use the pmreplay command to replay a log file to review what happened during a specified privileged session. The program can also display the log file in real time.

When using Safeguard for Sudo, enable keystroke logging by configuring the log_input and log_output variables. Please consult your sudoers manual for more information about configuring keystroke logging.

pmreplay can distinguish between old and new log files. If pmreplay detects that a log file has been changed, a message displays to tell you that the integrity of the file cannot be confirmed. This also occurs if you run pmreplay in real time and the Safeguard for Sudo session that generated the events in the log file is active; that is, the client session has not completed or closed yet. In this case, the message does not necessarily indicate that the file has been tampered with.

The name of the I/O log is a unique filename constructed with the mktemp function using a combination of policy file variables, such as username, command, date, and time.

Safeguard for Sudo sets the permissions on the I/O log file so that only root and users in the pmlog group can read it. That way, ordinary users cannot examine the contents of the log files. You must be logged in as root or be a member of the pmlog group to use pmreplay on these files. You may want to allow users to use Safeguard for Sudo to run pmreplay.

By default pmreplay runs in interactive mode. Enter ? to display a list of the interactive commands you can use to navigate through the file.

For example, replay a log file interactively by typing:

pmreplay /var/opt/quest/qpm4u/iolog/demo/dan/id_20130221_0855_gJfeP4

the results will show a header similar to this:

 Log File : /var/opt/quest/qpm4u/iolog/demo/dan/id_20130221_0855_gJfeP4 Date : 2013/02/21 Time : 08:55:17 Client : dan@sala.abc.local Agent : root@sala.abc.local Command : id Type ’?’ or ’h’ for help

Type ? or h at any time while running in interactive mode to display the list of commands that are available.
