Configure sudo (sudoers-list)¶

Requirements¶

To install ssh you will need the following:

• a installed and supported operating system (e.g. CentOS 6.x)
• root-access

Preliminary Note¶

sudo allows any user to run commands or a shell as root. Use this with care. This is better than allow everyone access the root-shell directly as there is no easy way to trace who was root when.

• http://centoshelp.org/security/sudo-an-advanced-howto

Install¶

sudo is installed by default.

visudo /etc/sudoers.d/user
