█▌ - SNOOPY LOGGER - █▌
█▌ █▌
█ ▐▌
█ Snoopy logger logs users or just root activities - Snoopy Logger, site is ▐▌
█ HERE, the old forums are HERE and HERE. ▐▌
█ Cons- You either log all, or just root. Once you have set this it can't be ▐▌
█ changed (that I could find) without recompiling it. ▐▌
█ If you want to log all; use apt-get. If you only want to log root only ▐▌
█ then I find it easier to compile it (as shown after). ▐▌
█ ▐▌
█ INSTALL: ▐▌
█ ```````` ▐▌
█ su ▐▌
█ apt-get update ▐▌
█ apt-get install snoopy ▐▌
█ You'll be asked y/n to install ld.so.preload-manager snoopy, select: ▐▌
█ y to log all, or n to log only root. ▐▌
█ ▐▌
█ You'll then have the 'Package configuration' window prompt you to agree; ▐▌
█ use arrow key to select yes, hit enter key. ▐▌
█ (my note: using apt-get /etc/ld.so.preload has /lib/snoopy.so) ▐▌
█ ▐▌
█ Or to compile it yourself: ▐▌
█ Check the site and HERE for the latest version. ▐▌
█ wget http://pkgs.fedoraproject.org/repo/pkgs/snoopy/snoopy-1.6.1.tar.gz/7a8186e45d959e1b3ed44805bfcd4467/snoopy-1.6.1.tar.gz
█ tar xvzf snoopy-1.6.1.tar.gz ▐▌
█ cd snoopy-1.6.1 ▐▌
█ cat README ▐▌
█ If you want to only log root: ▐▌
█ pico snoopy.h ▐▌
█ Change this line: ▐▌
█ #define SNOOPY_ROOT_ONLY 0 ▐▌
█ To: ▐▌
█ #define SNOOPY_ROOT_ONLY 1 ▐▌
█ ▐▌
█ ./configure ▐▌
█ make ▐▌
█ su ▐▌
█ make install ▐▌
█ Output will be similar to: ▐▌
█ install -m 755 -d /usr/local/lib ▐▌
█ install -m 755 snoopy.so /usr/local/lib/snoopy.so ▐▌
█ Snoopy shared library installed in /usr/local/lib. ▐▌
█ Run 'make enable' to actually enable snoopy logging. ▐▌
█ ▐▌
█ make enable ▐▌
█ output will be similar to: ▐▌
█ ./enable.sh /usr/local/lib ▐▌
█ Snoopy enabled in /etc/ld.so.preload. Check syslog messages for output. ▐▌
█ (my note: compile /etc/ld.so.preload has /usr/local/lib/snoopy.so) ▐▌
█ ▐▌
█ Restart programs that you want it to log, for example: ▐▌
█ /etc/init.d/apache2 restart ▐▌
█ /etc/init.d/ajaxterm restart ▐▌
█ /etc/init.d/ssh restart ▐▌
█ ▐▌
█ All executed commands will be logged in /var/log/auth.log ▐▌
█ ▐▌
█ Test it by running some cmds as a user, or root if you selected root only. ▐▌
█ Then the cmds ran listed here: ▐▌
█ tail -30 /var/log/auth.log ▐▌
█ (If you have programs set to execute on your MOTD, those will be there as ▐▌
█ well for each user.) ▐▌
█ ▐▌
█ MONITOR SELECTED APPLICATIONS: ▐▌
█ `````````````````````````````` ▐▌
█ As per the README states: ▐▌
█ Snoopy is placed in /etc/ld.so.preload to trap all occurrences of exec, if ▐▌
█ you wish to monitor only certain applications you can do so through the ▐▌
█ LD_PRELOAD environment variable - simply set it to /lib/snoopy.so before ▐▌
█ loading the application. For example: ▐▌
█ export LD_PRELOAD=/lib/snoopy.so ▐▌
█ lynx http://example.com/ ▐▌
█ unset LD_PRELOAD ▐▌
█ ▐▌
█ LOGCHECK IGNORE ENTRIES: ▐▌
█ ```````````````````````` ▐▌
█ Thanks to a post HERE by knx on how to have logcheck ignore entries from ▐▌
█ snoopy: ▐▌
█ Create this file: ▐▌
█ pico /etc/logcheck/ignore.d.server/snoopy ▐▌
█ Paste this in: ▐▌
█ ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ snoopy.* ▐▌
█ ▐▌
█ Create this file: ▐▌
█ pico /etc/logcheck/violations.ignore.d/snoopy ▐▌
█ Paste this in: ▐▌
█ ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ snoopy.* ▐▌
█ ▐▌
█ Note: I haven't tested this, nor does my Debian have a directory named ▐▌
█ 'violations.ignore.d' as stated HERE. ▐▌
█ find /etc/logcheck/ -name 'violation*' ▐▌
█ ls -alR /etc/logcheck/ ▐▌
█ 3 dirs: ▐▌
█ ignore.d.paranoid ▐▌
█ ignore.d.server ▐▌
█ ignore.d.workstation ▐▌
█ ▐▌
█ Read HERE, HERE and HERE for more info on logcheck ignore rules. ▐▌
█ ▐▌
█ If you use Logwatch, tutorial HERE, it will create a summarized report of ▐▌
█ all the entries in /var/log/auth.log logged by snoopy and mail those to ▐▌
█ you daily - html or text. The report would be in this format for example: ▐▌
█ snoopy: [mewbie, uid:0 sid:11183]: pico /jail/glftpd/etc/glftpd.conf : 4 Time(s)
█ ▐▌
█ CHANGE FILE SNOOPY LOGS TO: ▐▌
█ ``````````````````````````` ▐▌
█ By default Snoopy logs to auth.log. If you use syslog-ng (tutorial HERE) ▐▌
█ then to change this is very easy: ▐▌
█ pico /etc/syslog-ng/syslog-ng.conf ▐▌
█ Add these lines in their correct sections; destination, filter & log): ▐▌
destination df_snoopy { file("/var/log/syslog-ng/$HOST/snoopy"); };
filter f_all { level(debug..emerg) and not program("snoopy"); };
filter f_snoopy { program("snoopy"); };
log {
source(s_all);
filter(f_snoopy);
destination(df_snoopy);
};
█ Restart syslog-ng: ▐▌
█ /etc/init.d/syslog-ng restart ▐▌
█ ▐▌
█ You'll now see your new 'snoopy' log file in a directory with the name of ▐▌
█ your host: ▐▌
█ ls -al /var/log/syslog-ng/YOURHOSTNAME/snoopy ▐▌
█ ▐▌
█ NEW SNOOPY LOG ROTATION: ▐▌
█ If you changed the default logging location as above you must set up ▐▌
█ logrotation for it or it will grow until your server runs out of space. ▐▌
█ If you DON'T use syslog-ng (directions for users of syslog-ng after) then ▐▌
█ create a new logrotate config for it: ▐▌
█ pico /etc/logrotate.d/snoopy ▐▌
█ Paste in, changing to your own paths and preferences - note that ▐▌
█ 'create 640 root adm' should follow what your ls -al replied above for ▐▌
█ the 'owners': ▐▌
/var/log/syslog-ng/YOURHOSTNAME/snoopy {
daily
rotate 30
compress
delaycompress
notifempty
create 640 root adm
}
█ If you would like the snoopy log mailed to you daily add these 2 lines to ▐▌
█ the code above: ▐▌
mailfirst
mail my_email@gmail.com
█ ▐▌
█ You don't need to chmod it; it should have already perms 644: -rw-r--r--. ▐▌
█ To explain a briefly about what the logrotation code above does - It will ▐▌
█ rotate the snoopy log daily keeping 30 previous copies compressed with ▐▌
█ the newest rotated one not compressed (delay compress) and it won't ▐▌
█ rotate it if the log is empty, it will recreate a new log for it with the ▐▌
█ perms 640 and the owners root adm. ▐▌
█ ▐▌
█ If you want to test logrotation without actually rotating: ▐▌
█ logrotate --debug --force /etc/logrotate.d/snoopy ▐▌
█ ▐▌
█ Then to rotate manually- note if doing this for the first time and if you ▐▌
█ have put in settings to e-mail log and the log right now is larger than ▐▌
█ your e-mail client is setup to send it will error out first rotation, just ▐▌
█ rotate it again manually: ▐▌
█ logrotate --force -v /etc/logrotate.d/snoopy ▐▌
█ ▐▌
█ View your files again, you will now have snoopy & snoopy.1 ▐▌
█ ls -al /var/log/syslog-ng/YOURHOSTNAME ▐▌
█ ▐▌
█ If you do use syslog-ng then add the snoopy rotation to: ▐▌
█ pico /etc/logrotate.d/syslog-ng ▐▌
█ Paste in at the bottom of the file: ▐▌
/var/log/syslog-ng/YOURHOSTNAME/snoopy {
rotate 7
daily
compress
postrotate
/usr/sbin/invoke-rc.d syslog-ng reload >/dev/null
endscript
}
█ Or you could just add the log to syslog settings if you want to use the ▐▌
█ same: ▐▌
█ Has this: ▐▌
█ /var/log/syslog { ▐▌
█ Change to: ▐▌
█ /var/log/syslog /var/log/syslog-ng/YOURHOSTNAME/snoopy { ▐▌
█ ▐▌
█ Restart syslog-ng: ▐▌
█ /etc/init.d/syslog-ng restart ▐▌
█ If you want to test logrotation without actually rotating: ▐▌
█ logrotate --debug --force /etc/logrotate.d/syslog-ng ▐▌
█ ▐▌
█ Then to rotate manually: ▐▌
█ logrotate --force -v /etc/logrotate.d/syslog-ng ▐▌
█ ▐▌
█ TURN OFF OR REMOVE SNOOPY: ▐▌
█ `````````````````````````` ▐▌
█ To turn off of remove Snoopy: ▐▌
█ pico /etc/ld.so.preload ▐▌
█ Has this: ▐▌
█ /lib/snoopy.so ▐▌
█ Either delete that line, or comment it out: ▐▌
█ #/lib/snoopy.so ▐▌
█ If you want to remove the program permanently then delete this file: ▐▌
█ rm /usr/local/lib/snoopy.so ▐▌
