Review: RouterStation Pro + SR71A

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

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

Major MVPyBot Update

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

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

MVpybot Major Update

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:


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

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

    for part in outparts:
     outstuff+='PRIVMSG %s :%s\n' %(channel,part) 

   if cmd[1]=='6':

    for part in outparts:
     outstuff+='PRIVMSG %s :%s\n' %(channel,part)
   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

First of all, while I figure out how to have a system for hosting modules, I will put modules in 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.

MVpybot: Update 2

I just did another major update to MVpybot. Listeners have been implemented. A listener is a function that gets called whenever the bot receives data, or it can be set to only be called when a certain type (privmsg, join, part, etc) is received. As usual, the source is at the SVN repo.

Now for the technical stuff. A listener is just a python file in the listeners folder, with functions defined in it. A function’s name should be botfunction_type, where type is the type of message to listen for (privmsg, join, part, etc) or it can be ‘any’ for all data received by the bot. Here is an example logger function:


import time


timestamp=time.strftime('[ Session starting at %y-%m-%d %H:%M:%S ]')

def botfunction_any():
 timestamp=time.strftime('[%y-%m-%d %H:%M:%S] ')

As you can see from the example, plugins can be quickly enabled or disabled by toggling the ‘enabled’ flag. Also, ‘line’ is passed to the plugin. Not that anything outside of function definitions will be run when the bot starts.

Listeners can use the ‘socket’ variable to send data to the server, as shown in this example:



def botfunction_privmsg():
 print "called"
 out="PRIVMSG %s :Botfunction_privmsg called" %(channel)
 print out

Note that in the example, it uses botfunction_privmsg. To make listeners easier to write, the main program will automatically figure out these variables from privmsgs and pass them to the function:

info         #user info
msg          #the message
channel      #the channel the message was from (set to the sender for private messages)
sender       #the sender of the message
senderstuff  #info of the sender
isprivate    #whether or not the message was a private message as opposed to a channel message.

This only applies to privmsgs. All other events only get ‘socket’ and ‘line’ passed and have to figure out everything from ‘line’

That’s all for now.

MVpybot: Update

Well, i’ve finally gotten around to putting out some decent source for the bot. Here it is. There is also an addon system. To make an addon, simply make a python file in the botplugins/ folder and put your code in, like this:


def test():
 return("PRIVMSG %s :test" %(channel))

This would make a function called test. The variables channel, sender, nick, cmd, and run are passed to the function. The functions syscmd() and getlevel() are also passed to the plugin.

The default plugins that are included with the bot are ping, for pinging addresses, testplugin, for testing the bot, yacas, for doing math with yacas (delete it if you don’t have yacas installed) and getlevel, for demonstrating the ability to use the getlevel function in a plugin.

I have also set up a page for the bot, see the links bar below the logo.

Python IRC Bot in the Works

*** Update ***: Main page for bot here

I am currently writing a small, fast, small-footprint IRC bot in Python. More details as I finish the bot. The functions created so far:

  • Help (Displays Help)
  • Echo (Echo back a message)
  • Say (Send a message to a channel)
  • Spam (Send a message to a channel a specified amount of times)
  • Join (Join a channel)
  • Part (Part a channel)
  • Authorization (username+password)
  • Deauthorization
  • User lookup
  • Raw (Use raw IRC commands)
  • Uptime (Display uptime)
  • Math (Do math functions with Yacas)

Planned functions:

  • Encrypted passwords
  • Data storage, either in a text file or a MySQL DB
  • Channel mode control

This bot is not meant to be a complex bot, it is intended to be a fast, light bot that can be easily reprogrammed.

Linux iPhone Tethering over Bluetooth

A while ago I wrote about how to do a wifi iPhone tether with a SOCKS proxy. Now, I’ll be writing about a Bluetooth tether on 3.0/3.0.1 with a 3G/3GS. To make this work on 3.1, you will need to enable tethering separately, which can usually be done by installing the “Internet Tethering” package in Cydia. This does NOT rely on that script floating around, and will work on any Linux system with bluetooth. I used my Fedora 10 laptop for this.

A (Mostly) Complete OpenWRT Tutorial

I’ve attempted to write a complete OpenWRT setup tutorial, since many out there lack certain parts. This will cover the basics and the more advanced things you can do with OpenWRT. Read more for the tutorial.
