I would use xattr in python, but found the xattr's keys() is empty, does that indicate the libattr feature wasn't enabled? I've learned the libattr feature is disabled in ext3/ext4 by default, but how to enable it?
>>> import xattr
>>> x = xattr.xattr('tiger_8a428_userdvd.dmg')
>>> x
<xattr file='tiger_8a428_userdvd.dmg'>
>>> x.keys()

I have and embedded system which apparently, due to space considerations, is missing lots of normal commands. I can get the following information by "cat /proc/version":
Linux version 2.4.19-uc0 (...) (gcc version 2.95.3 20010315 (release)(ColdFire patches - 20010318 from http://fiddes.net/coldfire/)(-msep-data patches)) #461 Tue May 24 12:06:06 PDT 2011
At issue is the fact that, after some time, the system stops responding to the Network (e.g., you can ping it, then some time later you can't). We suspect that some sort of network monitor is accessing the device and causing the trouble, but don't know for sure.
What I would like to do is log some sort of useful network status information and/or be able to reset the network if I can figure out there is an issue from within the device.
I thought I had it all working using "/etc/init.d/network restart" but I've come to find out that the command is not recognised in this system. I also can't issue a "top" command to see what services are running. I can Telnet in, so I can try commands and see if they work.
Have any of you worked with such an abbr. system and if so, what might be around that I'm unaware of to help determine network status?
I installed pyxattr to play around with, and when I try to set them it says that the operation is not supported. Does Arch Linux not support xattr, or how do I enable them?
View 10 Replies View RelatedI've got a question about chattr command. is it possible to restrict a root access for this command. what i want is something similar to freebsd behaviour aka the kernel secure level. setting a particular security level results in limiting some operations (i.e changing immutable flags on files) by root. well, if someone gained an access to a machine in some way, nothing would stop him changing the file's flags. so the question is if it can be achieved with selinux?

View 1 Replies View RelatedI am using ubuntu hardy and python 2.6.5 (built from sources). For a custom python packager I need to rebuild python interpreter (python executable). I am new to linux and don't have much knowledge of gcc and other stuff. Here is the process:1. Copy python.c as myapp.c. myapp.c is in the same directory (python2.6.5) in which I have all the required files. 2. Using the syntax from makefile of python sources, here is my first command to produce myapp.o
Code:
gcc -pthread -c -fno-strict-aliasing -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I/home/zeno/installed/Python-2.6.5/Include -fPIC -DPy_BUILD_CORE -c myapp.c -o myapp.o
This produce myapp.o but throws a warning:
Code:
myapp.c:24:2: warning: no newline at end of file
Next is to produce the executable or python interpreter:
Code:
gcc -pthread -Xlinker -export-dynamic -o $@ myapp.o -L. -lpython2.6 -lpthread -ldl -lutil -lm -o myapp
This is causing an error:

How do you get correct ethernet/mac id of your local network card using python script? Most of the article suggests to parse the output of ipconfig /all on windows and ifconfig on linux. I am sure that this solution would work on windows but I am a linux starter and not sure the reliability of ifconfig on linux distros. Couple of other solutions on linux are:
Code:
def getHwAddr(ifname):
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
info = fcntl.ioctl(s.fileno(), 0x8927, struct.pack('256s', ifname[:15]))
return ''.join(['%02x:' % ord(char) for char in info[18:24]])[:-1]

Any tips/pointer/guide on what to do?
He was having problems with python and python-devel complaining about conflicting versions or some such when he was updating with yum. I told him (yes, a little of this is my fault) to try removing and reinstalling python and/or python-devel. Little did I know... He ran "yum remove python" and it listed over 600 (!) dependent packages to remove as well. Without telling me THAT part he clicked "y" and then watched as yum removed python and all sorts of other stuff (including yum--how's that for irony?) .
I have to go deal with this situation tomorrow morning but he has so blown away this system I almost don't know where to start. Sure I could re-download the rpm of python and reinstall, it but then I'd still have to one-by-one reinstall all the other rpms that were blown away by the python removal with yum. I do take at least partial responsibility for this. But really? 600+ packages and he clicked "y"? Yeesh. Oh, it's a RHEL 5 machine.
This borders on stackoverflow/superuser, but I guess it's a simple installation problem.I've installed python-twisted on my ubuntu 10.04 server, but it can't be found.This is what I get when I try to import something:
>>> from twisted.internet import reactor
Traceback (most recent call last):
File "", line 1, in [code]....
I've installed the package through apt-get.That way the module is installed in this folder: /usr/lib/python2.6/dist-packages/twisted with an __init__.py file.When I try to use python setup.py install (on the download from the site) it installs it to /usr/local/lib/python2.6/dist-packages/twisted, but it also does not find it there.
How do I install the Python module for Gnash?
But apart from that, what basic concept am I not understanding about installing packages on Linux?
I am used to installing packages using package managers - mostly apt-get and zypper. I have occasionally installed from source, often with no trouble. However I recently installed Gnash and discovered that it has a Python binding that must be compiled from source and this has led down a rabbithole making me feel stupider at each turn.
First, I attempt do a ./configure --enable-python in the gnash source dir. This ends up failing with an error that
package pygtk-codegen-2.0 isn't found
The lead developer, Rob Savoye, was kind enough to point me at packages.debian.org, telling me I just need to locate this package. After many failed searches, I found that the python-gtk2-dev package contains this ... file? script? Great, but I couldn't figure out how to obtain the python-gtk2-dev package. It doesn't exist in any of my openSUSE configured repositories.
So I headed to the GNOME site and searched, found that the PyGTK package contains pygtk-codegen. Download the tarball, cd, ./configure, and this fails because I don't have GLIB. After some more searching I use zypper to install glib2-devel (libglib-2.0 was already installed), and now PyGTK fails to configure because I don't have GObject.
Find that, download tarball, cd, ./configure, fail. I don't have gobject-introspection-1.0, apparently. I DO have gobject-introspection installed, and it's version is ≥ 1.0, but that's what the script says.
So I will readily admit I am new to Linux, but I have to be missing some basic step here. Can anyone give me a clue about any of the above? Is it normal to have to install one dependency after another like this? Is OpenSUSE the wrong distro? What would make this process not so horrible?
I want to write a shell script contains python one. So,the result of python one is flv file. I want the path of this is copied into a enviroment variable that i have to pass as a flag argument of another program (to convert into mp3). To individuate the result of python script I thought to use (in PWD)
Code:
ls | grep -E '^.*mp3$'
But my question is: How can I copy this result into enviroment variable?
On Ubuntu 9.10 I installed Python 3.1.1 successfully with Synaptic Package Manager. However the Python interpreter cannot find my scripts, currently in /home/dave/pycode. This appends _temporarily_ but python remains clueless about location of my scripts. Searched Internet and some speak of .rc or .bashrc or .profile..files. Found some of these and opened with Komodo : they are Linux script files and I am clueless as to how to modify.Currently I can import my scripts only if I change to the /pycode dir before running.Lutz's Python book says to change PATH file - Ha .Sobell's "A practical Guide to Ubuntu Linux" is no help. Ubuntu's own on line help is worth less than a fart in a hurricane. Ubuntu's gedit would not even open bash.bashrc.
