- Subj: Installing Tripwire Version 1.1 on Linux
-
- Hi,
- I installed tripwire on my linux box and came up
- with the following README.linux. At some point, I would like
- to publish it out on the internet on Comp.os.linux.*.
-
- I am also working on a Linux Security-HOWTO and would like
- to include a reference to your work in it with a copy of this
- attached README.
-
- Do you have any comments on the README or and suggestions
- before I publish it?
-
- Regards,
- Cal Page
-
- --------------------------- README.linux ----------------------------
- Summary
- Tripwire installed fairly easily on Linux using the following
- GNU tools; gcc, flex 2.4.5, and bison 1.18. The Linux kernel was
- at level 0.99.14.
-
- Build Problems:
- ---------------
-
- The following problems were encountered during
- the make:
-
- 1) yy_flex_realloc, yy_flex_alloc, and yy_flex_free were undefined
- globals when tripwire was linked. This was solved by adding the
- following lines to config.pre.tab.c:
-
- #include <malloc.h>
-
- void *yy_flex_realloc(void *x,int y) { return realloc(x,y); }
- void *yy_flex_alloc (int y ) { return malloc(y); }
- void *yy_flex_free (void *x ) { free(x); }
-
- 2) yyin and yyout were undefined during the compile. This was solved
- by adding the following line after the '#include <stdio.h>'
- in config.pre.tab.c:
-
- extern FILE *yyin,*yyout;
-
- 3) The 'src/Makefile' had to be changed after the $(YACC) line
- as follows:
-
- mv config.pre.tab.c y.tab.c
-
- This is because GNU's bison creates a different output file from
- yacc.
-
- 4) The 'Makefile' defined CC=gcc, FLEX=flex, and YACC=bison
-
- Run Problems
- -------------
-
- The following bugs were observed during testing:
-
- 1) The '@@include' macro failed in 'tw.config' with the error
- ---fatal flex scanner internal error--- End of buffer missed.
- This error showed up while running the acceptance test named
- 'tests/test.twpre.sh'
-
- 2) While running tripwire on an 'msdos' mounted partition, the following
- error was observed:
-
- ...
- Scanning: /msdos/msm/C&QC
- sig_md5_get: read(): Is a directory
- #
-
- The code is trying to read data from a directory, but gets a read
- error and then exits.
-
- 3) The following error was received while doing a '/dev R':
-
- ...
- Scanning: /dev/ptyqb
- sig_null_get: lseek(): Illegal seek
- #
-
- This is probably because we should not be doing a '/dev R'. It
- is unfair to expect random devices in '/dev' to lseek properly.
- The 'tw.config' should be changed.
-
- 4) On page 3 of the man page for 'tw.config' when the author states:
-
- "Note the differeence between pruning (via "!") and
- ignoring everything (via "N" template):..."
-
- They probably mean:
-
- "Note the ...
- ignoring everything (via "E"):..."
-
- 5) When you are creating a new database with the '-initialize'
- switch, tripwire ignores the '-d' switch. There is no command
- line error given for this.
-
- 6) There are four modes for runnung tripwire that are specified
- with switches that sometime agree with their functions. Specifically:
-
- Mode Switch
- --------------------------
- Generate -initialize
- Update -update
- Integrity <none>
- Interactive -interactive
-
- Samples:
- --------
-
- Here is a sample tw.config file that works reasonably
- well on Linux:
-
- #
- # Only check '/' disk partition with this
- # config file.
- #
- # Define a variable for searching /dev
- #
- @@define DEVSEARCH E+pinugsamc
- #
- # All Files in '/' disk partition. If you want
- # to check other mounted partitions, you would
- # add them after the '/ R' line.
- #
- / R
- #
- # Except /proc
- #
- =/proc E
- #
- # And /dev
- #
- /dev @@DEVSEARCH
- #
- # just /tmp
- #
- =/tmp
- #
- # End
- #
-
- For checking, this command works reasonably well:
-
- ./tripwire -v -interactive -loosedir -d databases/tw.db1 -c tw.config
