Programming :: Socket Programming: Insertion Of 0x00 Into The Stream?

Dec 5, 2010

When sending data over the socket, the sending socket includes 0x00 after each sent byte. I wonder how this can be avoided -- I just want to transfer the data in the tx_buffer as it is.

# ./serv &
[1] 6895
# ./EUG
EUG: Data to be transmitted: 0x35 0x32 0x30 0xff 0x03 0x31
EUG: Data - #Bytes transmitted: 6
./serv: Here is the message: '5'

Programming :: Run A Script At Usb Insertion?

Sep 20, 2010

I'm trying to run clamAV antivirus on USB insertion. I read about "udev" but it seems to be very complicated. I thought about running the script when the /media folder changes. I couldn't do that either.

I'm running MS "XP" on virtualbox and I'm sharing the /media folder from the host to the guest that's why I need an ON-DEMAND antivirus that scans the usb disk on insertion. (Light scan[neglecting archives and large files] is preferred to not overload the processor).

The script will contain the clamAV command line. The problem is how to set the execution time of the script...

Programming :: Python - Get Text File Data Into An Array On Python?

Nov 30, 2009

I've already used line split stuff to transform my data into something like this in a text file:


['1', '1', '3', '20.7505207']
['2', '1', '3', '23.0488319']
['3', '1', '3', '-1.5768747']
['4', '1', '3', '-26.4772491']


How can I get this on a python program so I can manipulate it as an array?

General :: Insertion Of Vbr And VBR End Delay More

Apr 22, 2011

I am using Ubuntu marvic amd64 10.10. I installed ns-allinone 2.34. then I inserted vbr traffic according to one of forum from this linux " Insertion steps of VBR into NS2.34" I made the following changes

Makefile, line 36 : CC = gcc-4.3
Makefile, line 37 : CPP = g++-4.3 in ns2.34/tools then Makefile : tools/vbr_traffic.o of 183

then I use the command cd ns-allinone-2.34/ns-2.34/ && mv ns ns234 && make after that I delete the ns. with the new command I run the script with every time puase time 0 and simulation time 200, 10 250, 20 300, 40 400..... with DSR after completion of simulation, when i was try to plot graph between throughputs of receiving bits vs Maximul end to end delay, every time I got the delay more than 90, 100, etc so how can I reduce that problem. I thought problem was in insertion of vbr.

I have a python script I wrote a while ago and now I would like to call that script from inside C. I know how to do one command from C, but how would you execute an entire script from C, and passing arguments? Like:

python( myprogram(1 2 3) );

So I can pass arguments to my script.

Ubuntu :: USB Insertion Hangs System / Stop It To Do So?

Dec 19, 2010

I'm running Ubuntu 10.10, 64-bit on an HP 8740w. Sometimes (I don't have the frequency yet, but it has happened a half-dozen times in the past couple of weeks) when I insert a USB storage device the system hangs, requiring a power-cycle. I have been careful to either eject or "safely remove" every USB device, but it still happens. I believe it only happens when I remove a device and later re-insert it, but I don't have enough data points to be sure.

Most of the time, I'm running VirtualBox, but I haven't captured the USB device in a VM.

First question - how can I go about figuring out what might be going wrong? Once it happens, my options are extremely limited (power switch). When this happened one time I left the system for 30+ minutes, and it did not recover.

Of course, when I wanted to see it, I did 10 insertions/removals without a hang.

Programming :: Piping In Bash Using Python?

Dec 16, 2010

I have a bash script that I want to import in to Python, mainly just to see if I can or not. However in the script I do use some piping of commands into sed to trim it down to what I need. When I tried doing it with the os.system() call, it didn't work. The exact error is

sed: -e expression #1, char 16: unterminated `s' command

However the command that was run can be run in bash without an error. Is there a better/another way to do this? For reference the command is:


locate -n 1 wp-config.php | sed 's/wp-config.php/
/g' | sed '/wp-config.php/ d' | sed '/^$/ d'

Programming :: Python - Global Name Not Defined

I found an interesting screencast online about how to make gtk Pyton apps. The thing is, though, the guy was using the interactive shell. I've been trying to get his code into a script, and have been having troubles.

Here's what I got:


It spits out the error "NameError: global name 'browser' is not defined"

I know I'm doing something wrong with how I'm telling it where to find "browser" and "text", but I can't figure out how to point it to the right place.

Programming :: Python Serial And Struct On 64 Bit?

May 14, 2010

For a work project, I've got a bunch of python code from about a year ago that controls the movement of our EVI-D30 camera over a ttyUSB connection. It used to work fine on a 32-bit Fedora box, but recently we moved our whole project over to a 64-bit Gentoo server, and the same code seems to be worthless on the new platform. I didn't write the code, so I'm have trouble figuring out how to fix it. Error messages usually look like this:


File "./", line 172, in pan
turn_callback(cmdStruct[0], cmdStruct[1])
File "./", line 147, in turn_callback
