The Reporter release notes declare support for these versions:
32 and 64-bit: Red Hat Enterprise AS release 4 and AP 5 (Nahant Update 4 or 5)
Red Hat, however, has a whole list of versions that almost match these names. See below for the list, plus which versions support what Linux version.
Red Hat Enterprise Linux 4 ( Nahant ), 2005-02-15. Uses Linux 2.6.9
In summary, no problem has been reported that is specific to a Linux distribution as long as it conforms to the above version specifications for 4 and 5 ( Kernel 2.6.9 and 2.6.18, respectively). Red Hat Enterprise Linux 6 will be supported with 188.8.131.52. In rare cases, if you encounter a problem with Reporter on a specific version, the diagnosis might be delayed as the version compiles and Blue Coat engineering can get to the root cause of the issue/symptoms.
Red Hat Enterprise Linux 7 has been extensively tested with Reporter version 9.5.X.X and is used in our lab environment as well as being used by many customers without issue however it is not officially validated with Red Hat.
