First ensure the following package dependencies are installed on your system:make, rpm-build, bash, gcc, glibc-devel, kernel-devel, kernel-headers, ncurses-devel, perl, and tcsh.
The kernel-devel and kernel-headers packages must match your running kernel exactly (as shown from the uname -r command).
Installed packages can be checked using rpm. For example:
# rpm -qa | grep rpm-build
Linux packages are typically installed using yum. For example:
# yum install [package_name]
Download the latest source rpm driver package:http://www.digi.com/support/productdetail?pid=2247&type=drivers
Capture and begin the driver compilation/installation: # script
# rpmbuild --rebuild 40002086_[X.]src.rpm
Change to directory /root/rpmbuild/RPMS/(arch):
# cd /root/rpmbuild/RPMS/(arch)
Where (arch) represents your system architecture (for example: i386, x86_64, etc...).
Use rpm to install the new driver package by typing:
# rpm -ivv dgrp-(version).(arch).rpm
Configure the adapters and load the module by typing the following from an XWindow or Xterm session:
Alternatively, to configure the adapter from the command line (non-GUI):
# dgrp_cfg_node init (ttyid) (ip_address) (number_of_ports)
The following example configures a 16 port PortServer with device names of ttya00 through ttya15:
# dgrp_cfg_node init a 192.168.1.1 16
Completing the installation, press:
# [Ctrl] d
A successful installation will create devices labeled /dev/ttyx## (where x represents the ttyid selected during the configuration). The adapter and port status can be confirmed with dpa.dgrp (Digi Port Authority):
If the installation failed, a file called "typescript" will have been created in the directory you were in when you typed the "script" command which will be useful for debugging errors.
