the version i found relevant for linux are rhel5 and rhel6
rmdstestclient is a demo tool in the ADS package.
I have checked that ADS 3.4.1.L1 is compatible with CentOS Version 7.
Operating Systems supported : Red Hat Enterprise Linux 6.x (64 bit) Red Hat Enterprise Linux 7.x (64-bit) (Qualification) Oracle Linux 6.x (Red Hat compatible kernel, 64 bit) (Qualification) Oracle Linux 7.x (Red Hat compatible kernel, 64 bit) CentOS Version 7 (Qualification)
Therefore, rmdstestclient in that package will be compatible with CentOS Version 7 too.
If you are using infra_tools0.0.6.L1, the README indicates that it doesn't support CentOS. However, it should be able to run on CentOS. I can run it properly on the CentOS:7 docker container.
