    1. Create a file named suid.set.ok that has a list of files, one per line, that can have the suid set.

When logging message to rsyslog make certain that you use some unique text that can easily found using grep. Such as __SUID_ALERT__

    2. Write a script named md5sum.sh that when passed "create" will find all files that have the group owner name of md5sum and do a md5 check sum on the file. Append the md5 checksum and file name to a file named md5.file.log in /var/log.

      When passed "check" md5sum.sh will find all files that have the group owner name of md5sum and do a new md5 checksum on the file. It will then check the new md5 genereate with the md5 in the md5.file.log. If match then continue else log error message to rsyslog. When logging message to rsyslog make certain that you use some unique text that can easily found using grep. Such as __MD5SUM_ALERT__

    3. Create a script named md5sum_logwatch.sh that will grep the log files for __SUID_ALERT__ and __MD5SUM_ALERT and send email message to root.
    4. Create a cron job to execute the md5sum.sh script, passing "check", followed by md5sum_logwatch.sh every morning at 6:00 AM.
  6. SED

Installing openldap
Add a manager account

10:00 Digital

The digital class has a test and then can continue in the Digital book with chapter 2.



12:00 Linux Prog

( Test has been moved to wednesday)

The Linux Prog class can continue to work with kickstart. Should end up with 3 different kickstart files on the web server.

Perform the following different type of installs

  1. GUI workstation where kickstart file is on floppy and RPMs are on local DVD.
  2. GUI workstation where kickstart file is on web server and RPMs are on DVD. (Time how long it takes to install so it can be compared when RPMs are on web server)
  3. GUI workstation where kickstart file is on web server and RPMs are on web server. (Time how long it takes to install so it can be compared when RPMs were on DVD)
  4. TUI webserver where kickstart file is on web server and RPMs are on web server.
  5. TUI openldap server where kickstart file is on web server and RPMs are on web server.
