The EasyServer II is the more up-to-date version of the EPS terminal server from Stallion. It comes in 8 and 16 port versions.
| Notes: | Main bootp server in the examples below is | 192.168.1.1 |
| Assigned IP address for the port server is | 192.168.1.92 |
Add an entry to
/etc/bootptab for the Terminal Server e.g.
easys:\ :ht=ether:\ :ha=00.60.1F.00.17.67:\ :sm=255.255.255.0:\ :hn:\ :ip=192.168.1.92:Add an entry to
/etc/hosts for the address e.g.
192.168.1.92 easys
Hit return a couple of times to allow the Console to check bootp again you should see the address and the Server Ready prompt.
If that fails you can enter an IP address manually. However, the automatic configuration option to load a configuration file cannot be used.
set privileged (Password is system)
Test the network connection with the command:
test internet 192.168.1.1
You should see:
Local 1> set privileged Privilege password: Local 1>> test internet 192.168.1.1 PING 192.168.1.1: 72 data bytes ... 80 bytes from 192.168.1.1: icmp_seq=1. time=20. ms 80 bytes from 192.168.1.1: icmp_seq=2. time=20. ms 80 bytes from 192.168.1.1: icmp_seq=20. time=20. ms .... 20 packets transmitted, 20 packets received, 0% packet loss. round-trip (ms) min/avg/max = 20/20/20 Local 1>>
All the help and manuals etc. are available via the browser as html pages.Remember, OSR 5.0.x comes automatically with Mosaic, OSR 5.0.4 also includes netscape You can use ANY PC on the network that has a browser
If you need on remotly and can't get a PPP connection working there is alwayslynx.Admin name for the Setup and Diags options are root with a password of system
Note: While you normally setup all the options via the above methods it
is a good idea to save all the settings so if the unit is replaced or
the settings get scrambled - this uses the tftp utility (make sure you enable it in inetd.conf)
Setup the Configuration file/tftpboot/ESII-8.CFGand include the settings for the ports using the examples below as a guide. For full details see later on in this guide.Add to this file all the settings required, these will be reloaded automatically when the Terminal Server Starts Up.
Add in a hosts entry to save remembering names.
SET INTERNET HOST xanth ADDRESS 192.168.1.1
Really Basic setup:
Example 1: A terminal on port 3 set to 38400
DEFINE PORT 3 Autobaud DISABLED DEFINE PORT 3 TERMINAL ansi DEFINE PORT 3 SPEED 38400 DEFINE PORT 3 STOP BITS 1 DEFINE PORT 3 DEFAULT PROTOCOL TELNET DEFINE PORT 3 DEDICATED xanthExample 2: A serial printer on port 3 set at 1200 baud
(Note for the Listener port numbers use 2000 + port number e.g. for port 3 use 2003, port 16 use 2016 )
DEFINE PORT 3 SPEED 1200 DEFINE PORT 3 ACCESS Remote DEFINE PORT 3 TELNET SERVER NEWLINE FROM TERMINAL <LF> DEFINE PORT 3 TELNET SERVER NEWLINE TO HOST <CRLF> DEFINE TELNET LISTENER 2003 CONNECTIONS ENABLED PORTS 3 ENABLED RAW MODE ENABLED DEFINE TELNET LISTENER 2003 IDENTIFICATION "Label Printer"See setting up a printer below for details on configuring Unix for a printer.
Example 3: Specify tty
This option predefines a port and associates it with one of the
/dev/ptty entries in /dev.
DEFINE PORT 3 SPEED 38400 DEFINE PORT 3 ACCESS Remote DEFINE TELNET LISTENER 2003 CONNECTIONS ENABLED PORTS 3 ENABLED RAW MODE ENABLEDNote: If setting up more than 4 devices this was make sure you spawn multiple svr_tty sessions via S88Easy to spread the load.
See setting up the svr_tty daemon below for details on configuring svr_tty.
Example 4: Standby Server
DEFINE PORT 3 Autobaud DISABLED DEFINE PORT 3 TERMINAL ansi DEFINE PORT 3 SPEED 38400 DEFINE PORT 3 STOP BITS 1 DEFINE PORT 3 DEFAULT PROTOCOL TELNET DEFINE PORT 3 PREFERRED xanthNow the user is asked to login to the server, (any old name will do) and at the Local> prompt open will connect to the preferred host while open machine will connect to the other machine.
It should be possible to have the config file setup on two different machines in /tftpboot each set to connect to themselves. If tftp is disabled in inetd.conf then the default will be 1st machine. A simple script to change inetd.conf can be used to 'switch' servers.
Example 5: Live System with ALL ports enabled as Wyse terminals.

This will be added as we find new options, the above has just scratched the surface of these units.
The LIST CHANGES and SHOW CHANGES commands displays all information that has been changed from the default settings. LIST displays permanent database changes, SHOW displays operational database changes.
Syntax for displaying permanent database changes is:
Local 1>> LIST CHANGES
Syntax for redirecting permanent database changes is:
Local 1>> LIST CHANGES > file_name HOST host_name
You can also see changes for specific tables such as Account,
Dialer, Internet, Server, Service, SNMP, System, Telnet Listener,
and Port.
Syntax for displaying specific permanent table information is:
Local 1>> LIST CHANGES ACCOUNT
The next example takes the output from SHOW SERVER and
redirects it to the file "server" on the remote host "kong"
Local 1>> SHOW SERVER > server HOST kong
Local 1>> SHOW PORT ALL > PORT 6
If you determine your communications server's IP address from
the network instead of locally, the communications server will
attempt to find and down load the default config file
/tftpboot/XXXX.CFG from its boot host. The "XXXX" represents
the model number of your communications server. For example it
may be ESII-8.CFG, LS-16.CFG, ESII-16.CFG, etc.
touch ESII-8.CFG
chmod a+w ESII-8.CFG
Local>> LIST CHANGES > ESII-8.CFG HOST catnip
You can attach a printer to the communications server and make it available to users on the network in both the UNIX and VMS/LAT Environment.
A telnet listener is a program that allows remote hosts to access devices such as printers and or modems on the communications server through a dedicated TCP (software) port.
You must assign a telnet listener port number to the communications server serial port in which the printer is attached. Telnet listener port numbers range from 2001 to 2032.
The port you are configuring must not be in use and you must be working on a port other than the one you are configuring.

/usr/local/lib/svr_print /usr/spool/lp/model/ESII (also attached to end of guide)
Add the printer as normal:
The following commands show you how to setup a unique queue name for using the remote printer with the LP Spooler Package.
When defining a printer, you give it a printer name, a printer interface file name (etc. standard, hp, citizen, ...) located in /usr/spool/lp/model and any additional parameters for your printer environment.
# /usr/lib/lpadmin -p PRINTERNAME -h -v/dev/null -m INTERFACE # /usr/lib/accept PRINTERNAME # enable PRINTERNAME # cd /usr/spool/lp/admins/lp/interfaces # mv PRINTERNAME PRINTERNAME.if
# cd /usr/spool/lp/admins/lp/interfaces # cp /usr/spool/lp/model/ESII PRINTERNAME
/usr/spool/lp/admins/lp/PRINTERNAME to
specify the communications
server's IP address (ipaddr) and the Telnet Listener's
TCP port (tcpport).
$ lp -d PRINTERNAME filename

To setup a fixed connection between a port on a communications server and a /dev/ttypx device node, a TELNET LISTENER must be configured to listen on the port and the port is configured to have ACCESS mode of REMOTE. Please use HELP command to see exact command syntax and a explanation for the two commands shown below.
CHANGE PORT port_number ACCESS REMOTE CHANGE TELNET LISTENER listener_port CONNECTION ENABLED RAW ENABLE CHANGE TELNET LISTENER listener_port PORT port_number ENABLE
where the listener_port is recommended to be 2000 + port_number.
Make sure the file /usr/local/bin/srv_tty is on
the machine (included in the print files from the robot or
on the BDS Utility CD).
Create the file /usr/local/lib/svr.data and add in the
devices you wish to map e.g.
ptyp7 192.168.1.92 2003 ptyp8 192.168.1.92 2004This shows
/dev/ttyp7 is associated with port 3 (2003)
on the terminal server 192.168.1.92, and ttyp8 on port 4.
If this is going to be a terminal, create an entry in
/etc/inittab (and /etc/conf/init.d/sio)
for the speed etc.
/etc/inittab
Tom1:23:respawn:/etc/getty ttyp7 oNow create an script in
/etc/rc2.d such as S88Easy, make
sure it runs AFTER tcp/ip has initalised to launch copies of svr_tty.
#!/bin/sh # # Script to start Easy Server tty daemon /usr/local/bin/srv_tty /usr/local/lib/svr.data
