- TRIPWIRE
- --------
-
- TRIPWIRE is a script designed to make easier the running of tripwire on
- multiple machines, but with only one floppy drive available.
-
-
- A safe, and recommended by gene, manner of running tripwire is to keep
- the databases and the config files on a read only floppy. A safer still
- approach is to also store the binaries on the floppy. Unfortunately, if
- you only have one floppy, you can run out of space while trying to support
- a number of machines/platforms on one floppy. The obvious solution is
- compression of some sort.
-
-
- TRIPWIRE is designed to take compressed binaries and databases, decompress
- them into a clean working area and run the [newly uncompressed] binary
- according to the appropriate config file.
-
-
- To use TRIPWIRE,
-
- 1)
- set up your config.h as follows (*before* compiling :)
-
- #define CONFIG_PATH "/usr/local/adm/tcheck/tripwire.configs"
- #define DATABASE_PATH "./Databases"
-
- #define CONFIG_FILE "tripwire.config_@"
- #define DATABASE_FILE "tripwire.database_@"
-
-
-
- 2) set up a floppy as follows
-
- /floppy/Databases
- -- directory, contains compressed Databases of the
- form: tripwire.database_XXX.sub.do.main
- tripwire.database_YYY.sub.do.main
-
- where XXX.sub.do.main and YYY.sub.do.main are
- hostnames (as returned by the hostname(1) command)
- of machines you are monitoring.
-
- There will be a unique database for each machine.
-
-
- /floppy/tripwire.configs
- -- directory containing compressed binaries for each of
- your systems. These are named for the hostname of
- the system. Continuing the above example, we would
- have
-
- /floppy/tripwire.configs/XXX.sub.do.main
- /floppy/tripwire.configs/YYY.sub.do.main
-
- if XXX and YYY were the same platform, then a single
- file with two links to the inode could be used.
-
-
-
- /floppy/tripwire.configs
-
- -- directory containing the *uncompressed*
- configuration files each of your systems. These are
- named tripwire.config_XXX.sub.dom.ain and
- tripwire.config_YYY.sub.dom.ain
-
- It is expected that each host will have a unique
- config file, although it is possible that disk-sparse
- clients might share configs. In this case, use multiple
- links to the same config file.
-
-
- 3) for each needed platform:
- -build the binary
- -run the binary tripwire to create the database
- -compress the binary and the database and store them onto the floppy
-
-
- 4) Mark the floppy readonly, re-mount and export to needed machines. NFS-mount
- the floppy as /usr/local/adm/tcheck (or edit the TRIPWIRE script to reflect
- your preference). Use a symlink on the floppy's local host to point
- /usr/local/adm/tcheck to the floppy if you can't control a floppy's
- mount point (stupid NeXT).
-
- 5) TRIPWIRE operates as follows:
-
- cd the the /tmp area
- forcably remove any hierarchy called tcheck.run
- create the directory tcheck.run, move to it and create a Databases
- directory
- uncompress the needed binary and database and store them in . and
- Databases
- run tripwire, mailing the output to root
- move back to the /tmp area and remove the tcheck.run hierarchy
