SysChk

I recently had the pleasure of using SysChk, a powerful tool for monitoring the integrity of file systems. The SysChk project keeps track of several changes to user and group ownership, modification times, file permissions, and MD5 hashes. This includes monitoring user ownership, group ownership, file permissions, modified time, and MD5 hash.

One of the stand-out features of SysChk is its simple configuration. All you need to do is edit the syschk.conf file, and add the directories you wish to monitor. For example, you could monitor the directories /usr/bin and /root. Additionally, SysChk offers several convenient options, including -h for accessing the main menu, -f for specifying the path for the configuration file, -s for specifying the path to the checksum database, -i for initializing the database, -c for checking the file system integrity, -d for dumping the whole database, and -l for specifying the path to the log file.

To get started with SysChk, you can use the following examples. If you want to create a new database or update an existing one, you can use the command syschk -i -f /etc/syschk.conf -s /var/lib/syschk.db. If you want to check your file system for changes, you can use the command syschk -c -f /etc/syschk.conf -s /var/lib/syschk.db.

Overall, I highly recommend SysChk for its ease of use and powerful monitoring capabilities.
