Network security device adds WiFi, runs Linux

Nov 12, 2007 — by Eric Brown — from the LinuxDevices Archive — 1 views

A Taiwanese network-appliance system integrator announced a wireless network security appliance that runs Linux. Drawing only 2.4 Watts, AR Infotek's fanless Teak 3018 is equipped with four auto-sensing Ethernet interfaces, plus WiFi, and targets SMBs (small- and medium-sized businesses).

The Teak 3018 appears to be almost identical to AR Infotek's 3011 model, which was released in mid-2006. The new device adds mini-PCI based WiFi, however.

The Teak 3018 reportedly is based on a 500MHz AMD LX800 Geode processor, along with its CS5536 integrated northbridge/southbridge companion chip. The system can be configured with 128MB to 512MB RAM of onboard DDR 266/400MHz RAM. It can boot from an internal CompactFlash or DiskOnChip flash module.

Typical application with redundant WAN links and DMZs

Housed in a steel chassis, the device measures 10.8 x 5.7 x 1.7 inches and is equipped with a drive bay for a 2.5-inch hard drive, according to the company. There's also a PCI expansion card for security applications, such as cryptography. The four auto-sensing 10/100 Ethernet ports include two ports with “bypass” function to maintain network availability in case of appliance failure.

The following lists the Teak 3018's key features:

  • Processor — 500MHz AMD LX-800 and CS-5536 chipset
  • Memory — up to 512MB of on-board DDRAM SDRAM
  • Storage:
    • 2.5-inch hard drive bay
    • DiskOnChip and CompactFlash sockets
  • Wired/wireless networking:
    • 4 x autosensing 10/100 Base TX (including two bypass); based on Intel 82551ER controllers
    • 820.11g WiFi
  • Other I/O:
    • RS-232 serial port
    • 2 x USB 2.0 ports
  • PCI slot for additional expansion
  • Dimensions –10.8 x 5.7 x 1.7 inches (275 x 145 x 44 mm)
  • Power — 20-Watt external AC power adapter

The unit is compatible with a variety of open source operating systems, says the company, including Red Hat, Fedora, FreeBSD, and OpenBSD.


AR Infotek did not disclose specifics on pricing or availability of the Teac 3018.
