CHAPTER 7: UNIX/RTEL Host Setup
In general, rteld is the only application that users might have to run
interactively. The lp and lpr filters are called by the host’s printing subsystem.
7.2 Installing the Reverse Telnet Software
This section describes the procedure used to install the Reverse Telnet
software (RTEL) on a UNIX host machine.
If you received the distribution on DOS-format floppy disks, you will have
to recreate the RTEL file structure on a UNIX machine. The DOS floppies
contain all the download files (*.SYS), a single tar archive containing the
RTEL source files (rtel_src.tar) and the RTEL executables for all system types
(lp_filter.*, lpr_filter.*, rteld.* and talk.*). Because of DOS filename length
restrictions, you will have to rename the lp and lpr filter executables with the
correct UNIX file names. When the tar archive is untarred (using tar xvf
./rtel_src.tar), the resulting file names will be correct.
The EPS includes reverse Telnet executables for the following operating
systems: MIPS RISC/os, SunOS (68xxx and SPARC based), Digital ULTRIX
(RISC-based, non-VAX), IBM
®
AIX (on RS6000-style machines), SCO UNIX
(for 80386- and 80486-based machines), and HP
®
-UX (68xxx-based). You
should read the README files (included with the distribution media) for
a detailed list of the supported environments and software version levels.
7.3 Reverse Telnet for Unsupported UNIX Machines
If your operating system is not one of those listed above, you must modify
the distributed software and compile executable code for your machine.
For more information, refer to the README files in the /tmp/rtel and
/tmp/rtel/source subdirectories. Recompiling the software for your machine
should be largely uneventful, unless your machine is missing system include
files or libraries. If you encounter problems building the software and cannot
resolve them with the help of the README files, contact Technical Support.
7.4 Installation Procedure
The lpinstall script you will use in this procedure creates and links necessary
files and directories if they do not already exist.
There is also an uninstall script that will remove the binaries and source
code from the system area, stop the queueing daemon, and restore the system
to the pre-installation state.
