Using the Firebox Arm/Disarm LED under Linux

Friday, November 14th, 2014

Quick script for controlling the arm/disarm LED, created from the info here. I took a quick stab at trying to make WGXepc run on Linux but didn’t have any luck, so I just created this instead.

#!/bin/sh

lport='dd of=/dev/port seek=1167 bs=1'
fport='dd of=/dev/port seek=1179 bs=1'

steady="\x00"
green="\x13"
red="\x0b"
flash="\x10"
off="\x03"

case $1 in
r|red)
 printf $red | $lport 2>/dev/null
 ;;
g|green)
 printf $green | $lport 2>/dev/null
 ;;
off)
 printf $off | $lport 2>/dev/null
 ;;
steady)
 printf $steady | $fport 2>/dev/null
 ;;
flash)
 printf $flash | $fport 2>/dev/null
 ;;
*)
 echo 'Usage: wgled (red|green|off|steady|flash)'
 ;;
esac

Unfortunately since it’s just a single bidirectional LED, there’s no way to get the green and red on at the same time.

These addresses and values are for the X-Core-e boxes. For other boxes, look in the WGXepc source (available here) to find values and addresses. The value that you printf is the value you want to write, while the seek value for dd is the address, converted to decimal.

Still not sure how to control the disk or expansion LED.

Mini-review: Intel 7260HMW (Updated 2014-11-18)

Wednesday, July 2nd, 2014

I bought this to replace a Wi-fi card in my laptop (Thinkpad X300) since the standard card had flaky Linux support. The 7260HMW is a half-length miniPCIe card with 2xU.FL connectors.

Good:

  • 802.11ac support
  • Good Linux drivers, works out of the box on Debian testing
  • Built-in Bluetooth 4.0
  • Supports AP Mode
  • Low power usage

Bad:

  • General signal strength is slightly on the poor side (happens on both Linux and Win7 so it’s not a driver issue)
  • Only 2 spatial streams supported, only 2 antennae. If you currently have 3/4 spatial stream 802.11n APs, this card could possibly see worse performance than a 3/4 stream client.
  • AP Mode is completely half-assed, only supports 2.4GHz band which means no 802.11ac Also it only supports 1 AP or STA at a time. See the dump below, section “valid interface combinations”.

Other:

  • If your laptop has a Bluetooth LED in addition to Wi-fi like on many Thinkpads, this card won’t interact with it. In fact, having multiple BT cards (this card+builtin BT) can even cause the LED to not even work with the builtin BT if you choose to leave it installed (Easy enough to remove on my X300 but difficult on my W510).
  • The Wi-fi LED will just be on solid, rather than on+blink on activity. Does this on Win7 and Linux, and none of the settings in /sys/class/leds/phy0-led/trigger seem to get the desired behavior. If you want this functionality, you’ll have to write a script to manually toggle the LED (There’s a netdev LED trigger out there, but it was very unstable for me).

Stuff:

Dump of phy info. Note the no-IR flags on the 5GHz frequencies, meaning 5GHz AP mode is not supported.

Using the Sierra MC5725’s GPS on Linux

Sunday, June 15th, 2014

After not being able to get this card’s GPS to do anything, I forgot about it for a while. Now that I’ve had some time, I revisited it and was able to get it working. Read on to see how.

Installing OpenWRT on a Firebox X550e

Wednesday, July 17th, 2013

I recently came into possession of a Firebox X550e Core that was thrown out due to a bad power supply. Turns out OpenWRT (or almost any OS for that matter) is pretty easy to install on this thing. Read on for some photos and a how-to.

An RGB LED for your RSPro

Thursday, August 11th, 2011

As I mentioned in my review, the Routerstation Pro only has a single user-programmable LED. However, it has 7 GPIO lines that can easily be attached to more LEDs. Read on for instructions and pictures.

Review: RouterStation Pro + SR71A

Saturday, April 2nd, 2011

After finally deciding to replace an aging WRT54GL, I decided to not get a typical poor-performing home router and go for a more professional product. The RouterStation Pro fit my needs perfectly, with its expandability and performance being far beyond most home routers. Read on for the review and pics.

MVpybot stuff

Monday, January 3rd, 2011

Just a few minor fixes, new version should be in SVN.

Major MVPyBot Update

Saturday, August 14th, 2010

The bot now supports “hot reloading.” The bot can now reload itself without losing connection due to a new wrapper.

You need to run ‘mvpybot.py 0’ because start.py is broken now. Substitute the zero with a different server number if you want to connect to a different server.

MVpybot Major Update

Saturday, June 26th, 2010

There is a somewhat-major bot update in the works. The plugins system has been completely redone. Instead of plugin files being used for whatever functions can be found in them, they now have to explicitly register functions. Here is an example, the rewritten ping plugin:

#!/usr/bin/python

def register():
 registerfunction('ping', ping)
 addhelp('ping', help_ping)

def ping():
 outstuff=''
 print "ping called"
 if (len(cmd)<2):
  return('PRIVMSG %s :Incorrect usage. Syntax: ping (4|6) <address>.' %(channel))
 else:
  if cmd[1]=='4' or cmd[1]=='6':
   if cmd[1]=='4':

    output=syscmd(['ping','-c','5','-i','0.2',cmd[2]])
    outsplit=output.split('\n')
    outparts=outsplit[-3:-1]
    for part in outparts:
     outstuff+='PRIVMSG %s :%s\n' %(channel,part) 

   if cmd[1]=='6':

    output=syscmd(['ping6','-c','5','-i','0.2',cmd[2]])
    outsplit=output.split('\n')
    outparts=outsplit[-3:-1]
    for part in outparts:
     outstuff+='PRIVMSG %s :%s\n' %(channel,part)
  return(outstuff)
  else:
   return('PRIVMSG %s :Error: protocol must be either 4 or 6' %channel)

def help_ping():
 return('PRIVMSG %s :Pings an internet address. Usage: ping (4|6) <address>.' %(channel))

A plugin’s register() function is called when the plugin is loaded. It can use registerfunction(), addlistener(), and addhelp(). You can use each function as many times as you want, in case you have multiple functions and/or listeners, or if you want to include help with your plugin.

More MVpybot stuff

Friday, April 30th, 2010

First of all, while I figure out how to have a system for hosting modules, I will put modules in mattventura.net/mvpybot/modules. Secondly, a bug tracking system is being set up.

Lastly, I will be improving the plugin system, and I will try to make older plugins backwards-compatible, but the new system will make the plugin system more efficient. Instead of always having to scan for functions in plugins whenever a certain command is called, all function plugins will register in a list of plugins upon being loaded. This has the advantage of also allowing plugin authors to specify what functions are actual functions for the bot to use.
