The /usr/sbin/twprint command is used to view encrypted Tripwire reports and databases.
The twprint -m r command will display the contents of a Tripwire report in clear text. You must, however, tell twprint which report file to display.
A twprint command for printing Tripwire reports looks similar to the following:
/usr/sbin/twprint -m r --twrfile /var/lib/tripwire/report/<name>.twr |
The -m r option in the command directs twprint to decode a Tripwire report. The --twrfile option directs twprint to use a specific Tripwire report file.
The name of the Tripwire report that you want to see includes the name of the host that Tripwire checked to generate the report, plus the creation date and time. You can review previously saved reports at any time. Simply type ls /var/lib/tripwire/report to see a list of Tripwire reports.
Tripwire reports can be rather lengthy, depending upon the number of violations found or errors generated. A sample report starts off like this:
Tripwire(R) 2.3.0 Integrity Check Report Report generated by: root Report created on: Fri Jan 12 04:04:42 2001 Database last updated on: Tue Jan 9 16:19:34 2001 ======================================================================= Report Summary: ======================================================================= Host name: some.host.com Host IP address: 10.0.0.1 Host ID: None Policy file used: /etc/tripwire/tw.pol Configuration file used: /etc/tripwire/tw.cfg Database file used: /var/lib/tripwire/some.host.com.twd Command line used: /usr/sbin/tripwire --check ======================================================================= Rule Summary: ======================================================================= ----------------------------------------------------------------------- Section: Unix File System ----------------------------------------------------------------------- Rule Name Severity Level Added Removed Modified --------- -------------- ----- ------- -------- Invariant Directories 69 0 0 0 Temporary directories 33 0 0 0 * Tripwire Data Files 100 1 0 0 Critical devices 100 0 0 0 User binaries 69 0 0 0 Tripwire Binaries 100 0 0 0 |
You can also use twprint to view the entire database or information about selected files in the Tripwire database. This is useful for seeing just how much information Tripwire is tracking on your system.
To view the entire Tripwire database, type this command:
/usr/sbin/twprint -m d --print-dbfile | less |
This command will generate a large amount of output, with the first few lines appearing similar to this:
Tripwire(R) 2.3.0 Database Database generated by: root Database generated on: Tue Jan 9 13:56:42 2001 Database last updated on: Tue Jan 9 16:19:34 2001 ================================================================= Database Summary: ================================================================= Host name: some.host.com Host IP address: 10.0.0.1 Host ID: None Policy file used: /etc/tripwire/tw.pol Configuration file used: /etc/tripwire/tw.cfg Database file used: /var/lib/tripwire/some.host.com.twd Command line used: /usr/sbin/tripwire --init ================================================================= Object Summary: ================================================================= ----------------------------------------------------------------- # Section: Unix File System ----------------------------------------------------------------- Mode UID Size Modify Time ------ ---------- ---------- ---------- / drwxr-xr-x root (0) XXX XXXXXXXXXXXXXXXXX /bin drwxr-xr-x root (0) 4096 Mon Jan 8 08:20:45 2001 /bin/arch -rwxr-xr-x root (0) 2844 Tue Dec 12 05:51:35 2000 /bin/ash -rwxr-xr-x root (0) 64860 Thu Dec 7 22:35:05 2000 /bin/ash.static -rwxr-xr-x root (0) 405576 Thu Dec 7 22:35:05 2000 |
To see information about a particular file that Tripwire is tracking, such as /etc/hosts, use the following command:
/usr/sbin/twprint -m d --print-dbfile /etc/hosts |
The result will look similar to this:
Object name: /etc/hosts Property: Value: ------------- ----------- Object Type Regular File Device Number 773 Inode Number 216991 Mode -rw-r--r-- Num Links 1 UID root (0) GID root (0) |
