Additionally, the Linux distribution on the RaQ 3 is based on the
RedHat Linux 6.0 distribution for x86-compatible processor systems.
You can run most pre-compiled x86-based commercial software
packages on the RaQ 3, as long as the software does not require a
mouse, keyboard or monitor. Ensure that the software is compatible
with the Linux 2.2 kernel and the glibc library.
Configuration files
If necessary, you can change some of the configuration files for the
RaQ 3 services for development purposes, but this may void your
warranty. Please read your warranty card before making any changes.
!
Caution: Changing any of the following configuration files can
dramatically affect the operation of the services configured by
means of the RaQ 3’s Web-based administration service or the
administration service itself.
The services and some of their associated configuration files and
directories are the following:
• Email
/etc/inetd.conf
/etc/sendmail.*
/etc/mail/
