As you may be aware, ‘AT’ allows you to run a command or script at a particular time (say at midnight) and ‘CRONTAB’ allows you to run commands and scripts at scheduled times and at regular intervals. If you have SuSE or an openSUSE system in a multi-user environment then it is important to control access to the crontab and at utility to ensure system availability and security. This is one of the many steps in the system hardening procedures.

pwsafe is a free opensource password manager which manages the passwords in an encrypted password database. pwsafe is a command line software but can interact with X11 selection & clipboard. pwsafe is compatible with CounterPane’s PasswordSafe Win32 program versions 2.x and 1.x. It’s unfortunate that there hasn’t been much of a development to this great tool since September 2005 but whats on hand is good enough to serve the purpose.

Sudo which is su “do” allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments.sudo allows a permitted user to execute a command as the superuser or another user, as specified in the sudoers file. The real and effective uid and gid are set to match those of the target user as specified in the passwd file and the group vector is initialized based on the group file.
