I'm trying to get a simple Pyro example running (taken from this page), this is the code:
import Pyro.core
import Pyro.naming
class JokeGen(Pyro.core.ObjBase):
def joke(self, name):
return "Sorry "+name+", I don't know any jokes."
daemon=Pyro.core.Daemon()
ns=Pyro.naming.NameServerLocator().getNS()
daemon.useNameServer(ns)
uri=daemon.connect(JokeGen(),"jokegen")
daemon.requestLoop()
When I run this script with Python 2.6.5 and Python 2.6.6 (tried both on Ubuntu 10.04 and Debian Squeeze), I'm always getting this error:
Traceback (most recent call last):
File "/home/ingo/tools/python/pyroserver.py", line 9, in <module>
ns=Pyro.naming.NameServerLocator().getNS()
File "/usr/lib/pymodules/python2.6/Pyro/naming.py", line 176, in getNS
reply = self.sendSysCommand(NS_SYSCMD_LOCATION,host,port,trace,1,bcaddr)
File "/usr/lib/pymodules/python2.6/Pyro/naming.py", line 76, in sendSysCommand
raise Pyro.errors.NamingError("could not find NameServer")
Pyro.errors.NamingError: could not find NameServer
What's wrong with the script? How can I create that nameserver?
Run pyro-ns in another terminial first. That is the Pyro object broker.

I'm using nxt-python to connect to my nxt brick from my raspberry pi.
After some struggle with the python 3.2 versions of the bluetooth and usb libraries it requires i've managed to get it to connect via bluetooth and ask for a passkey. After some more struggle i found that i could type bluetooth-agent PASSKEY & (and replace PASSKEY with the passkey) in the terminal before running the python script that connects with the nxt brick and as far as i know that works fine. But now it throws an error. Connecting with USB throws a different error.
Here's the error i get with both methods (USB & BT) and debug enabled:
USB: True BT: True Fantom: False FUSB: False FBT: False
Traceback (most recent call last):
File "/usr/local/lib/python3.2/dist-packages/nxt/locator.py", line 138, in find_one_brick

No brick was found.
Is the brick turned on?
For more diagnosing use the debug=True argument or
try the 'nxt_test' script located in /bin or ~/.local/bin

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

nxt.locator.BrickNotFoundError
Because i know python i could probably fix the errors by just editing the source code, but i'm affraid i'll break something. I've tried editing it (keeping backups of every file i edit) and then it gets past a couple of lines before throwing another different error.
EDIT
When i try to import using python 2 it gives me this error:

I've downloaded the v2.2.2 stable instead of cloning the master commit and it runs fine under python2. Too bad it isn't python3 though.
I am new to jira-python and have run into an issue with using jirashell.
jira-python was installed from documentation given here: http://jira.readthedocs.org/en/latest/
When I try to start jirashell using:
ubuntu#ip-10-0-0-12:~$ jirashell -s https://jira.atlassian.com
I get the following error:
Traceback (most recent call last):
File "/usr/local/bin/jirashell", line 11, in <module> sys.exit(main())
File "/usr/local/lib/python2.7/dist-packages/jira/jirashell.py", line 248, in main

File "/usr/local/lib/python2.7/dist-packages/jira/client.py", line 1871, in _create_oauth_session
oauth['consumer_key'],
KeyError: u'consumer_key'
I have also tried to get to a server using basic auth but that returns the same error. Using curl works fine, but I wanted to see the objects that are getting returned and get help as I develop by python-jira integration.
Thank you for any insight.
I'm trying to run virtual machine set on Computer with Windows 7 (my main laptop) from my netbook (Ubuntu system).
On Ubuntu I've prepared python script:
from vboxapi import VirtualBoxManager
import sys
sys.path.append("/home/myLogin/Downloads/sdk/bindings/webservice/python/lib")
mgr = VirtualBoxManager("WEBSERVICE", {'url':'myIP', 'user':'myServerLogin', 'password':'myPassthere'})
vbox = mgr.vbox
name = "Muszelek"
mach = vbox.findMachine(name)
session = mgr.mgr.getSessionObject(vbox)
progress = mach.launchVMProcess(session, "gui", "")
progress.waitForCompletion(-1)
mgr.closeMachineSession(session)
I'm getting error:
Installation problem: check that appropriate libs in place

NameError: global name 'IWebsessionManager_logonRequestMsg' is not defined
Any idea how could I solve this issue?
Is it problem with libs on my Windows Machine?
I just had the exact same problem on my Mac. The issue is that VirtualBox_wrappers.py imports VirtualBox_client.py (which defines the global name in question) in a try block and continues (pass) if it can not be imported
try:
from VirtualBox_client import *
except:
pass
the issue is that VirtualBox_client.py depends on ZSI, which was not installed, so the import failed. Once I did
easy_install zsi
everything worked as expected.
It seems that the class is not found! Have you tried to look for the webservice api if they are available?
I had a similar issue, I looked in /usr/lib/virtualbox/sdk/bindings and I didn't find the webservice folder only xpcom was in there, so I just included the webservice folder from the sdk and all worked fine.
Several times I've seen mention that for asynchronous ping is good to use twisted.
I written implementation on threads (like Ping a site in Python?)
But on ~200 threads i have crush
On page http://twistedmatrix.com/trac/wiki/ProjectsUsingTwisted i find
txNetTools - Ping, traceroute, icmp, etc., implemented in Twisted, and a library for those who want to build their own network tools.
Has anyone used this library?
I tried to use it ping.py:
Traceback (most recent call last):
File "ping.py", line 23, in <module>
class Pinger(ICMP):
NameError: name 'ICMP' is not defined
if change:
class Pinger(**ICMP**):
to
class Pinger():
Traceback (most recent call last):
File "ping.py", line 54, in <module>

File "/usr/local/lib/python2.7/dist-packages/twisted/internet/udp.py", line 123, in _connectToProtocol
self.protocol.makeConnection(self)
AttributeError: Pinger instance has no attribute 'makeConnection'
Maybe I'm doing something wrong or not understand?
P.S. twisted 12.0
If you are running sandbox/ping.py, then the exception you report doesn't make sense. That file has this import near the beginning:
from txnet.icmp import ICMP, Packet, ECHO_REQUEST
This defines the ICMP name. The Pinger class comes later, extending it. I can successfully run this demo program (though it fails with an unrecognized message type when handling the response on my sytem).
Perhaps you have an old version of the code, or have modified it somehow, or are running a different ping.py?
I just installed libgmail on CentOS 5, python 2.6 with easy_install. There was a problem, until i installed mechanize manually. After that easy_install said OK and i wrote 1st test program from the sample i googled:
import libgmail
ga = libgmail.GmailAccount("someaccount#gmail.com", "mypassword")
ga.login()
folder = ga.getMessagesByFolder('inbox')
for thread in folder:
print thread.id, len(thread), thread.subject
for msg in thread:
print " ", msg.id, msg.number, msg.subject
print msg.source
I get the following error message:
Traceback (most recent call last):
File "gm.py", line 4, in <module>
ga.login()
File "build/bdist.linux-i686/egg/libgmail.py", line 305, in login

File "build/bdist.linux-i686/egg/mechanize/_rfc3986.py", line 62, in is_clean_uri
TypeError: expected string or buffer
It seems, i get a problem not with my python code, but with libgmail installation. Any clues, anyone?
libgmail is deprecated and has stopped developing, since gmail started offering imap access.
Use imaplib or similar (twisted.mail comes to mind, example code here).
