pyicmp (ping in python)

I'm  writing program for my programming class this semester (more about it later) and I needed some means of doing ping and traceroute in pure python, because just parsing output of ping (traceroute) commands is not very reliable or cross-platform.

So I created library which uses raw sockets and Internet Control Message Protocol (ICMP) to do basically anything with ICMP allows, but I focused on ping and traceroute.

It's probably only IPv4 (IPv6 was not tested and it's not supported, however some messages may work, I didn't study ICMP6 to see which messages are the same). IPv6 support is planned.

Usage is very simple:

ping:

import pyicmp.ping
p = pyicmp.ping.Ping('1.2.3.4')

traceroute:

import pyicmp.traceroute
t = pyicmp.traceroute.TraceRoute('1.2.3.4')

Yeah, it's that simple.

See docstrings for each classes for more details.

Oh and there is one bad thing... It requires root (administrator for windows) permissions and it'll remain this way, it's not possible to bypass this problem.

Easymail

I needed simple way for sending emails from python (debug info from server app), so I created VERY simple library to wrap smtplib into something more useful. Here is a link:

Claws mail python plugin

I am using Thunderbird right now, but as I got new PC I will be installing Archlinux on it, so I ask myself if it's time to move to something lighter and more extendable by plugins.. as I like Python, using python as plugin language would be great.

I picked Claws-mail which is a great, capable and lightweight email client supporting both GPG encryption/signing and Python plugins..

But there is virtually no documentation on writing those plugins :'( So I just tried it, open console from claws-mail menu and tried it as described in demo.

But I got

Traceback (most recent call last):

  File "<string>", line 1, in <module>

NameError: name 'clawsmail' is not defined

When I tried accessing clawsmail modul. After a while, I found that all you need to do is first import clawsmail modul.

import clawsmail

Simple ^_^

I will probably make some kind of tutorial for this (python plugins in claws mail) so no one else have to do the "digging".

lookbehind regex in PHP

Today, I was facing a problem how to split something like following text

a="Some Text" b="Some more Text" c="Even more text about \" this text\"" d="aaaaaaa"

into array, into pairs key => value. I couldn't just use explode(), because spaces could be inside the quotes..

After a little searching, I founded that solution lies in lookbehind regular expressions.. Nifty things ^_^

This

/(?<![\\\|=])\" /

expressions would split it into following array:

array (

  0 => 'a="Some Text',

  1 => 'b="Some more Text',

  2 => 'c="Even more text about \" this text\"',

  3 => 'd="aaaaaaa"',

)

so exactly what we wanted :)

YaCy on Archlinux

Today I decided to deploy YaCy on my VPS running Archlinux. I installed package and all went well until I noticed, that no images are being displayed. After some searching (30 minutes?) I finally figured it out.

To correctly show (generated) images, YaCy requires X Server and libcups, even on server running only in console.

I already requested adding those two packages into dependecies, but until it's done, if you having problem running YaCy without X server, just run "pacman -S xorg-server libcups" and it should be ok.

PHPUnit_Util_Log_XML

I was doing some work in PHPUnit and one of the request from company was export to xml.. So I was thinking, how to do that? I found some tutorials online, but I run into error Class 'PHPUnit_Util_Log_XML' not found in...

I found out that PHPUnit_Util_Log_XML was renamed into PHPUnit_Util_Log_JUnit ...

I just thought I can save someone searching..
