Linux Access Server

This week I configured a Linux-based access server rather than purchasing a new router solely for that purpose. I recruited my wife's old HP Mini 1101 netbook she stopped using after she got her new 15" HP laptop. I wanted to configure a server that I could use to log into all devices out-of-band in the event of a layer 3 failure and for layer 2 only devices like frame-relay switches. Check out the specifications.

Server
  • HP Mini 1101 (My wife's old netbook she no longer uses)
  • 1GB RAM, Intel Atom, 160GB HDD
  • Ubuntu 12.10 Server
  • Openssh-Server (for remote server management)
  • Xinetd Telnetd (for remote access to network equipment)
  • Ser2net (server to network proxy)
*I disabled the default Ubuntu firewall for ease of use since I would be opening so many ports and because Linux based firewalls combined with SELinux seem to be a hassle at times. Plus my Vyatta Internet Router handles firewalling.

Console Hardware
  • Sabrent 7-port USB Hub
  • 7 RS232-Serial-to-USB Adapters
  • 7 Cisco Console Cable
Port Mappings
  • Access Server IP 192.168.1.141 (accessible over SSH or Tenet)
  • Telnet 192.168.1.141:2000 (HQ Router)
  • Telnet 192.168.1.141:2001 (HQ Switch 1)
  • Telnet 192.168.1.141:2002 (HQ Switch 2)
  • Telnet 192.168.1.141:2003 (HQ Access Switch)
  • Telnet 192.168.1.141:2004 (Frame Relay Switch)
  • Telnet 192.168.1.141:2005 (Branch Router 1)
  • Telnet 192.168.1.141:2006 (Branch Router 2)

Pictures soon!

Lab Pics: New Frame Relay Switch

Here are some pictures of my newest edition to my lab --- primarily my new Cisco 2811 Frame Relay switch with three WIC2T interfaces (supporting a total of 6 Serial WAN connections).

Two New Projects

(1.Just ordered a Cisco 2811 and a couple of WIC-2Ts and smart serial cables for my new Frame Relay switch.

(2. Working on a Linux-based (CentOS or Ubuntu) terminal access server for out-of-band access to my growing lab as opposed to buying a Cisco router solely for that purpose.

Stay tuned...
