# Adding Linux Computers to a Linux Data Collector

End of Support - Linux Data CollectorsFrom release version 9.0.5, we will end support for Linux Data Collectors in the ControlUp Real-Time Console. While you won't be able to create new SSH connections to Linux from the Console, current connections will continue to work. Note that you won't be able to edit the current settings. To install the Edge DX Agent onto Linux devices, see [here](https://support.controlup.com/docs/edge-dx-agent-distribution-and-installation-for-linux).

Linux can be added to a Linux Data Collector (LDC) when the LDC is created or at any time afterward. For details, see [How to create a Linux Data Collector](/tim-reorg/docs/how-to-create-a-linux-data-collector). They can be added:

- Individually by IP address
- As a group from a range of IP addresses
- As a group from a list in a text file

Linux machines are recognized by their IP addresses and domain names. When you enter the IP address, the machine must be able to successfully pass a reverse lookup to resolve the domain name. Both the machine on which the ControlUp Real-Time Console is installed and the machine assigned as the Linux Data Collector must be able to resolve the reverse DNS lookup. The most efficient way to do this is to ensure that there is a DNS server that can return the domain name value based on the IP address entered.

NoteA workaround to having a reverse DNS resolution is to edit the *%windir%\System32\drivers\etc\hosts* file on both the ControlUp Console server machine and the Linux Data Collector machine.NoteIf you want to add Linux computers using a list in a text file, the file can include either the hostname, IP address, or FQDN of each computer. Separate computers in the list with line breaks, commas (,), semi-colons (;), or colons (:). E.g:  
![line 1 shows '10.1.4.183'. line 2 shows 'ILHQSQL02.smartx.dom'. line 3 shows 'ILHQWEB01'. Line 4 shows '10.1.5.179'.](https://cdn.document360.io/098100b7-b9da-4bea-b4b9-017140ab863e/Images/Documentation/linux.png)

#### To add Linux computers to an LDC:

1. In the **Home** ribbon bar, select **Add Computers**. The Add Computers window opens with the **Search Active Directory tab** selected
2. Open the **By IP address** tab
3. Select the **Linux Data Collector** machine that you want to add the computers  
![Add Computers window. The Linux Data Collector dropdown is highlighted.](https://cdn.document360.io/098100b7-b9da-4bea-b4b9-017140ab863e/Images/Documentation/linux%202.png)

4. The **Ping Timeout** and **Connection Timeout** values control how long the system waits for a response from each Linux computer during computer discovery and SSH connections. By default, the timeouts are 200ms for Ping and 1,000ms for connections. To modify these values, in the **Connection Settings** area, in the **Ping Timeout** and **Connection Timeout** fields, change the values as required. ![Connection Settings section.](https://cdn.document360.io/098100b7-b9da-4bea-b4b9-017140ab863e/Images/Documentation/linux%203.png)

NoteIf the **Ping Timeout** and **Connection Timeout** fields are not visible, to the right of the Connection Settings field, select the arrow to drop the menu down.

5. Once you configure the IP range & other settings, select **Scan** and wait for the machines to be discovered and checked. During this entire process, a progress bar appears below the table (#2 below). When the process is completed, the progress bar disappears.

The system lists all of the computers in the table. It then launches a discovery process for each of the computers in the list, and, for those it detects, attempts to connect via SSH, using the specified credentials. During this process, color-coded icons, indicating the connection status of each computer in the list, appear in the left column (#1 in the illustration below). If the system succeeds in connecting to a computer **Done** appears in the Description column. ![Table displaying several computers.](https://cdn.document360.io/098100b7-b9da-4bea-b4b9-017140ab863e/Images/Documentation/linux%204.png)

![Icon legend. Blue indicates 'Connected successfully'. Black indicates 'Attempting to connect'. Red indicated 'Connection error/failure.'](https://cdn.document360.io/098100b7-b9da-4bea-b4b9-017140ab863e/Images/Documentation/linux%205.png)

The Linux Data Collector begins installing the required RPMs on the selected machines. When the installation process is complete, the Linux computers are attached to the Linux Data Collector. In addition, they are added to the list of managed computers at the bottom of the organization tree.
