    FreeBSD command reference Command structure Each line you type at the Unix shell consists of a command optionally followed by some arguments , e.g. ls -l /etc/passwd | | | cmd arg1 arg2 Almost all commands are just programs in the filesystem, e.g. "ls" is actually /bin/ls. A few are built- in to the shell. All commands and filenames are case-sensitive. Unless told otherwise, the command will run in the "foreground" - that is, you won't be returned to the shell prompt until it has finished. You can press Ctrl + C to terminate it.

  • Bootstrap Protocol, BOOTP, Is the Recommended Way to Establish Communications from the Host to the Printer in an Internet Protocol Environment
    BOOTP Bootstrap protocol, BOOTP, is the recommended way to establish communications from the host to the printer in an internet protocol environment. BOOTP obtains booting data from the bootptab file. With the proper information stored in the bootptab file, the printer can find its own name and IP address and boot from the network without any intervention, even for a first time boot. 1. Verify that the bootpd and bootptab files are in the correct directories: UNIX: /etc or /usr/etc directory OS/2: \TCPIP\ETC (for bootptab) and \TCPIP\BIN (for bootpd) LAN Server: MPTN\ETC (for bootptab) and \MPTN\BIN (for bootpd) Type: ls bootp* 2. Edit the hosts file to add the printer internet addresses and names: 128.07.60.30 P340-mktg 128.07.60.31 P340-sales For OS/2, use the TCP/IP Configuration Notebook under the Services tab to add the printer internet addresses and names. 3. Some UNIX hosts may require an explicit update to the arp table to add the new entries. This command is host-specific; check your host documentation for details. arp -s ether P340-mktg 08:00:11:01:00:45 arp -s ether P340-sales 08:00:11:01:00:46 The ether switch indicates that you are providing an Ethernet address. 4. Set up the bootptab file. 5. Start or restart the inetd or bootpd daemon. For OS/2 Warp, LAN Server 4.0, and UNIX, use the bootpd daemon. Here is a sample bootptab file; check your host system documentation to see which fields your implementation of BOOTP supports.

  • Configuration Management with Newfig William Lefebvre and David Snyder – CNN Internet Technologies
    Auto-configuration by File Construction: Configuration Management with Newfig William LeFebvre and David Snyder – CNN Internet Technologies ABSTRACT A tool is described that provides for the automatic configuration of systems from a single description. The tool, newfig, uses two simple concepts to provide its functionality: boolean logic for making decisions and file construction for generating the files. Newfig relies heavily on external scripts for anything beyond the construction of files. This simple yet powerful design provides a mechanism that can easily build on other tools rather than a single monolithic stand- alone program. This provides for a great deal of flexibility while maintaining simplicity. The language is a combination of boolean logic and output statements, and also provides for macros and other essential elements. All output is written to channels: an abstraction which provides for extensive configurability. Examples are provided that show the tool’s power and flexibility. A description is also provided of the efforts undergone at CNN to integrate this tool in to a sizable infrastructure. The paper concludes with a discussion of future improvements. Introduction When we sought out a tool for automated sys- tems configuration, we were looking for certain prop- As the number of systems in an infrastructure grows, the administration problem grows with it. erties that we believe would be beneficial in our envi- Unless the engineering staff grows accordingly, at some ronment. We wanted the system to be idempotent, point the management of the systems will need to be congruent, deterministic, transportable, extensible, and automated. This realization is nothing new, and several fail-safe.
