Morning Star ExpressRouting with the Morning Star Express Plus for LAN-Dial and Leased Line Setup Instructions
The Morningstar Express (MSE) router operating system is modeled after the UNIX operating system. The console interface is actually a stripped down version of "sh". You can do shell-like things including history, I/O redirection, and create simple shell scripts. When the Morningstar Express router is booted, it checks for the existence of an "rc.boot" file. If found, it executes instructions in this file. There is always an "rc.default" file which contains enough instructions to get the machine up and console ready. This file is hardwired into memory and cannot be changed. It is executed if "rc.boot" is corrupted or not present. The MSE router is not shipped with an "rc.boot" file. Here is a listing of important files on the MSE router:
All of these files reside in FLASH memory on the MSE router. They must be saved after modification or creation or the changes will not be permanent through reboots. There is a rudimentary ed-like editor which you can use to modify or create files in FLASH. You can also download files to FLASH using TFTP or FTP. To get a listing of commands on the MSE router, type "?". For a listing of processes running, type "ps ax". For a listing of files in FLASH, type "ls". Example rc.boot (no encryption) hostname <NAME-OF-ROUTER> console tty2 version ifconfig lo0 127.1 getty tty2 9600 nowait respawn ifconfig enet0 <CUSTOMER-LAN-IP-ADDR> netmask <CUSTOMER-NETMASK> frd addr 38.2.<XXX>.<YYY> netmask 255.255.255.0 56000 tty0 ignore-cd arp -s 38.2.<XXX>.1 tty0:<ZZZ> route add default 38.2.<XXX>.1 snmpd inetd gated ****NOTE: DO NOT ADD GATED UNLESS YOU HAVE 0.9.1164 or GREATER.**** XXX = ethernet ip of POP lan YYY = customer end of frame-relay ZZZ = DCLI number of PVC Example gated.conf

You can get help by typing "?". Here is an example session using the line editor: # edit rc.boot rc.boot: read 11 lines, 283 characters hostname test1 edit> ? Commands are:
Leave append mode with ^D or a dot (`.') on a line by itself. Leave edit mode with a return. A line number can be a number, a dot (current line), a minus sign (`-', previous line), a plus sign (`+', next line), or a dollar sign (`$', last line). A range is either a line number or two line numbers separated by a `-'. edit> w rc.boot: wrote 11 lines, 283 characters edit> q # After writing and quitting out of the editor, you must SAVE the file to FLASH using the "save" command. Using TFTP to Modify or Create Files Given the state of the line editor on the MSE router, it is often easier to create or modify your MSE router files on a UNIX machine with your editor of choice and use TFTP to transfer the files to the MSE router: # # tftp 192.33.4.253 tftp> get rc.boot rc.boot Received 285 bytes in 0.6 seconds tftp> tftp> get inetd.conf inetd.conf Received 1150 bytes in 0.7 seconds tftp> tftp> get resolv.conf resolv.conf Received 40 bytes in 0.1 seconds tftp> tftp> get gated.conf gated.conf Received 10 bytes in 0.2 seconds tftp> tftp> quit # # save rc.boot # save inetd.conf # save resolv.conf # save gated.conf # Once this is done, you can reboot the router with the new configuration.
