Install the Traps Agent for Linux
Traps for Linux is designed to protect Linux servers and operates transparently in the background as a system process. Traps also extends exploit and malware protection to processes that run in Linux containers. When you install Traps on a Linux server, Traps automatically protects any new and existing containerized processes regardless of the container solution (for example, docker). Each Linux server receives a single license which includes protection for container processes.
After you install Traps for Linux, it is typically not necessary to interact with the Traps agent; however, to perform common actions, such as initiating a manual check in with Traps management service, you can use the command-line utility (also available for Mac and Windows) named Cytool. Cytool is available in the
/opt/traps/bin/cytooldirectory and must be run as root or with root permissions.
Before installing Traps on a Linux server, verify that the system meets the requirements described in Traps for Linux Requirements.
If you intend to use SELinux, make sure to enable it before you proceed with the Traps installation. This ensures that Traps disables any injection-based modules which cause compatibility issues. If you later enable SELinux, you must reinstall Traps to avoid any compatibility issues.
You can then install Traps using software distribution tools that support Linux such as Satellite or Chef, or you can manually install Traps using the following workflow:
- Download the Traps installation script from the Traps management service.Traps management service saves the installation script using the name you provided to identify the package.
- Copy the installation package to the Linux server on which you want to install the Traps software.For example, to copy the file securely from a local machine to the Linux server:user@local ~ $scp linux.sh firstname.lastname@example.org:/tmplinux.sh 100% 21MB 1.2MB/s 00:18
- Log on to the Linux server.For example:user@local ~ $ssh email@example.comWelcome to Ubuntu 16.04.3 LTS (GNU/Linux 4.4.0-1041-aws x86_64) * Documentation: https://help.ubuntu.com * Management: https://landscape.canonical.com * Support: https://ubuntu.com/advantage Get cloud support with Ubuntu Advantage Cloud Guest: http://www.ubuntu.com/business/services/cloud 0 packages can be updated. 0 updates are security updates.

Done [*] Starting Traps security services (systemd) DoneAdditional options are available to help you customize your installation if needed. Use the --help option to print the help for the installer.Use the--no-kmoption if you do not want to install the Traps kernel module. If you install Traps without the Traps kernel module or your Linux server runs an unsupported kernel version, Traps will operate in asynchronous mode where the agent will obtain a verdict for the executed ELF file in parallel to its execution and terminate it if a malware verdict is obtained.The script installs the files for the Traps app for Linux in the/opt/trapsfolder with the Cytool utility available at/opt/traps/bin/cytool.After the Traps agent successfully connects to the server for the first time and retrieves a valid license, the agent begins protecting the Linux server.If the Traps agent cannot register with the Traps management service, the agent does not retry registration. To retry, reinstall the Traps agent on the server.
