1. Download CDP Agent
See Obtaining Linux CDP Enterprise Agent.
2. Configure APT Repository
You should also configure an APT repository on Debian and Ubuntu to manage upgrades of CDP Standard Edition (See Upgrading Enterprise Agent for Linux), to install the unzip utility, etc.
First, modify your /etc/apt/sources.list to include the R1Soft repository, and then download the R1Soft apt gpg key.
3. Option 1 - Install Agent Using APT
 | Notice You must be a Linux root user to install CDP Agent. |
Once you have configured the APT repository, you can execute the following command to install CDP Agent:
Option 2 - Install Agent Using DPKG
4.1 Make Sure You Can Unzip the Download
Most Linux distributions come with the unzip utility pre-installed. To determine if you have the unzip utility, run:
This should return an output similar to the following:
If it returns the following output, you need to install the unzip utility first:
To install unzip on Debian or Ubuntu:
4.2 Extract the ZIP File
We recommend creating a temporary directory to which you can extract the contents of the ZIP file.
1. Use the mkdir command to create a temporary directory (in our case, cdp-agent).
2. Use the mv command to move the archive to that directory. Note that Linux file names are case sensitive. Make sure you type the name correctly (in our case, "r1soft-enterprise-agent-linux64-4.2.0.zip").
3. Use the cd command to go to that directory.
4. Use the unzip command to extract the files.
4.3 Install the Packages
| Notice You must be a Linux root user to install CDP Agent. |
The archive you have extracted contains two folders: one with .deb packages (in our case, "deb-linux64") and one with .rpm packages ("rpm-linux64"). If you are installing on Debian or Ubuntu, choose the .deb package.
Each folder contains a set of CDP components:
- r1soft-setup
- r1soft-cdp-enterprise-agent
- r1soft-cdp-agent
- r1soft-cdp-async-agent-2-6
You will need to install all of them in one step. Use the cd command to go to the folder with the packages (in our case, "deb-linux64") and run the following command:
DEB 32-bit (x86) / DEB 64-bit (x86_64)
5. Install CDP Linux Device Driver
CDP Device Driver is a proprietary, loadable Linux kernel module distributed by R1Soft. It is loadable at run-time without restarting Linux, and you do not need to recompile your Linux kernel to use it. R1Soft does not provide prebuilt modules for the popular kernels anymore, so you will have to compile the module from source.
| Notice You need to have loadable modules enabled as a feature in your kernel. This is an advanced feature on all popular Linux distributions. |
45.1 Compiling CDP Kernel Module Against Kernel Headers or Kernel Source Tree
Using a pre-built binary module package is not possible anymore. You will have to compile this module against kernel headers for the current running kernel. In order to do so, we can build using your installed linux-headers package on your Linux server (see section 4.2 on installation of header packages). In order for kernel module compilation to work, you should have Internet connectivity directly from the Linux server you are installing CDP on, to TCP port HTTPS (443), on the host krnlbld.r1soft.com.
In order for kernel module compilation to work, you should have Internet connectivity directly from the Linux server you are installing CDP on, to TCP port HTTPS (443), on the host krnlbld.r1soft.com.
You can test connectivity with the following command (this may take a minute):
5.2 Install Kernel Sources
If you are using an unmodified kernel provided by Ubuntu installer, install the kernel-devel package:
5.3 Verify that the Source Matches Your Running Kernel (Does not apply to Debian or Ubuntu)
Sometimes, the kernel-devel package is newer than the installed and running kernel. If the kernel-devel is too old and not found, please follow the instructions on how to setup access to older yum packages as documented here.
5.4 Build the CDP Kernel Module Online (direct Internet connection to R1Soft build server)
To attempt to build the kernel module, run the following command (this may take several minutes):
If module has been compiled and installed successfully, you will see an output similar to the following:
4.5 Build the CDP Kernel Module Offline (without direct Internet connection to R1Soft build server)
If there is no direct Internet connection between your CDP server and R1Soft build server, it is still possible to compile the kernel module. In this case, this will be tree-step process. First, you will have to create tarball file with the kernel headers. When you should copy this tarball file from the server to some other computer which has Internet connection to R1Soft build server. From this computer you should upload the tarball to the R1Soft build server and wait for the compilation to finish. When it is finished, you should download binary module and copy it back to the CDP server. Start with executing the following command:
After running this command, you will see:
Last Step
- Copy the generated tar.gz file and paste it to a computer with Internet access.
- Go to https://krnlbld.r1soft.com/ and upload the .tar.gz file to build a kernel module.
- After the build, you will download a kernel module.
- Copy this module and paste it to your Linux Server and the folder /lib/modules/r1soft.
- Restart the Server (/etc/init.d/cdp-agent restart).
