APPENDIX A: Linux Commands and Source Code The console server platform is a dedicated Linux computer optimized to provide monitoring and secure access to serial and network consoles of critical server systems and their supporting power and networking infrastructure. Tripp Lite console servers are built on the uCLinux distribution as developed by the uCLinux project. This is GPL code, whose source can be found at http://cvs.uclinux.org. Some uCLinux commands have config files that can be altered (e.g., portmanager, inetd, init, sshd). Other commands you can run and configure (e.g., loopback, bash (shell), ftp, hwclock, iproute, iptables, netcat, ifconfig, miitool, netstat, route, ping, portmap, pppd, routed, setserial, smtpclient, stty, stunel, tcpdump, tftp, tip, traceroute). Below are most of the standard uCLinux and Busybox commands (and some custom Tripp Lite commands) that are in the default build tree. The Administrator can use these to configure the console server, and monitor and manage attached serial console and host devices: addgroup * adduser * agetty arp arping bash busybox cat * chat chgrp * chmod * chown * config cp * date * dd * deluser * df * dhcpd discard dmesg * echo * erase eraseall false * find flashw flatfsd ftp gen-keys getopt * gettyd grep * gunzip * Add a group or add a user to a group Add a user Alternative Linux getty Manipulate the system ARP cache Send ARP requests/replies GNU Bourne-Again Shell Swiss army knife of embedded Linux commands Concatenate FILE(s) and print them to stdout Useful for interacting with a modem connected to stdin/stdout Change file access permissions Change file access permissions Change file owner and group Tripp Lite tool to manipulate and query the system configuration from the command line Copy files and directories Print or set the system date and time Convert and copy a file Delete USER from the system Report file system disk space usage Dynamic Host Configuration Protocol server Network utility that monitors the discard port Print or control the kernel ring buffer Print the specified ARGs to stdout Tool for erasing MTD partitions Tool for erasing entire MTD partitions Do nothing, unsuccessful Search for files Write data to individual flash devices Daemon to save RAM file systems back to FLASH Internet file transfer program SSH key generation program Parses command options Getty daemon Print lines matching a pattern Compress or expand files 272
