The first terminal and console access server to use Linux as the embedded OS.
The TS2000 is a terminal and console access server that can be used by ISPs, ASPs and e-retailers to remotely and securely manage serial console ports in server farms. As a terminal server, the TS2000 connects local or remote clients to the Ethernet LAN, allowing both ISPs and corporate remote-access applications to use serial lines and analog modems. As a console access server it connects to the console ports of servers and networking equipment and allows the system administrator to remotely and securely monitor and manage servers.
Features include RADIUS socket authentication, direct Telnet to serial ports, secure shell connections (SSH), IP packet filtering and RFC2217 support. The TS2000 supports up to 32 RS-232 serial ports in 1U of rack space.
Applications include console port management, dialup remote access, industrial/commercial automation and Ethernet-attached serial board replacement.

Newest member of the DIL/NetPC family.
SSV Embedded Systems introduced the ADNP/1486, a small PC/AT-based embeddable single-board computer module that plugs into a standard 128-pin Quad-in-Line (QIL) socket. The miniature PC comes with embedded Linux pre-installed in Flash memory and includes a full TCP/IP stack, a Telnet server for remote login, an FTP server and an embedded web server with CGI.
Based on a 3-bit, low-power AMD 486SX processor with 100MHz, the ADNP/1486 provides a complete embedded-PC/AT architecture, plus 16MB of DRAM and 4MB of Flash. Peripheral functions include a COM1 serial port, 20 digital I/O lines and a 16-bit ISA expansion bus interface with programmable chip selects for connecting external logic and devices via the 128-pin QIL socket interface.
Manufacturer: SSV Embedded Systems
Suggested Retail Price: $225 US in quantities of 1,000
Board functions in industrial temperature range of -40° to 85° C.
WinSystems has made available the LPM-TX STD Bus single-board computer, an industrial-grade product based on the Intel Tillamook Pentium processor. The SBC is based on x86 processors and supports PC-compatible software, has long-term availability and offers extended termperature operation. It provides a migration path for STD Bus systems while maintaining hardware, I/O and software compatibility over a full industrial temperature range. Designed for systems that need a small format board that is PC-compatible, it is targeted at embedded and industrial application.
The LPM-TX operates at a system clock of 166MHz and includes 16KB of code and 16KB of data cache, plus a floating-point processor for math-intensive applications. It comes with either 32MB or 64MB of surface mounted synchronous DRAM, and the SDRAM is soldered directly to the printed circuit board to protect against shock and vibration. An onboard 32-pin socket supports up to a 288MB M-Systems Disk-On-Chip Flash memory device for use as a solid-state disk. The Intel 430TX PCI chip set contains core logic to provide PC-compatibility for the I/O and bus interface, including the keyboard controller, 16-channel interrupt controller and real-time clock.
Onboard peripherals include seven DMA controllers, three 16-bit counter/timers, two interrupt controllers, keyboard controller, speaker port and battery-backed, real-time clock. Two independent serial channels, each with RS-232 and optional RS-422/485 levels, USB port, LPT interface and a mouse port are also included, all on a single 4.5" × 7.0" STD Bus board.
Manufacturer: WinSystems, Inc.
Model: LPM-TX STD Bus SBC
Suggested Retail Price: $995 US with 32MB SDRAM
Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
