Internally, little is known about Reynolds and Reynods.
From the telnet login to an ERALink server on June 16, 2008. ERALink reports:
CentOS release 4.4 (Final) Kernel 2.6.9-55.EL on an i686
On Jan 6, 2010, a different ERALink server reported:
CentOS release 4.4 (Final) Kernel 2.6.9-55.EL on a 2-processor x86_64
The underpinning of the ERALink server is a modified IBM UniVerse database version 10.1.16. Since Reynold's adoption of U2 the product line was sold by IBM and is now owned by Rocket Software, documentation specific to this database can be found on their website.
It appears as if it is only an era-server running over telnet (insecure might I add). You can start the era-prompt by logging in as "era" or "eralink". Other users on the system are rsupport, and radmin both of which have installed home directories.
We also know that the default terminal is a mutilated proprietary version of tvi955 internally referred to as rtvi955. Few terminal emulaters of this sort are available, one of them is by EricCom. The default terminal type of vt100 is available and can be set for the bash session with
export TERM=vt100 if you have shell access.
