|Issue||The Linux Agent is not populating into the UI on the Machines tab despite the installation of the RPM file on the linux agent.|
|Cause||The problem is that the agent is sending malformed information to the server which causes merge errors in the database, which results in incomplete data on the device. Thus, the reason for UI not displaying device.|
Alternatively, there can also be a connectivity error between the agent and server which can be determined by checking if the RC4 cipher is installed on the console server or not.
|Resolution||There are two approaches to examining the agent in 22.214.171.124 of ECAT. The first and most obvious is to determine if the RC4-MD5 cipher is installed on the console server. Without this cipher, it is impossible to connect Linux agents. The steps are highlighted below:|
Installing RC4 Ciphers
WARNING! Microsoft considers RC4/MD5 ciphers weak encryption, and TLS 1.0 is an older encryption technology. Future enhancements of the ECAT software will remove these dependencies, so this is mostly only a current limitation on the Linux agents to be considered vulnerable at this time so enable these ciphers and protocols with caution.
