Python Sketches Hidden In NOOBs SD-Card From Blocked RaspberryPi

A little embarassed to even ask this, but...

In the last few evenings, a typical Linux session has been creating a root file system on an SD card, mounted on /mnt/sd2 (partition2 of card). At the same time watching a movie from the HD, mounted at /mnt/HD.

I was wondering if everything going through /mnt might be slowing things down at all. The answer should be 'no' since everything is mounted to 'root' and that doesn't seem to be a problem, but maybe /mnt is handled differently than root.

Just ran an experiment with 'top' and seeing what is happening with mplayer and debian bootrap:

Code:

5562 walter    20   0 62980  23m 9.8m R  38.0  2.7   4:01.75 mplayer
 1852 root      20   0 32048  12m 3728 S   3.0  1.4   2:08.92 Xorg
 2020 walter    20   0  276m  14m   9m S   2.0  1.7   1:32.03 gnome-mplayer
 2070 root      20   0     0    0    0 D   1.0  0.0   0:25.22 mmcqd/0

Can't really tell much from this, except that 'mmcqd/0' must be the bootstrap program unpacking things in the sd card. It kind of begs dumb question number 2: the unpacking process is crawling down the terminal screen, why is it not using more cpu to speed itself up? Must be the sd card can only accept writing to it at that speed, average about 1 second per package? Can't pull the card out at the moment, but pretty shure it's class 10, although suspiciously cheap from Eb.

One week user of Ubuntu v15 and I have tried to install the file Python-3.5.0a1.tar gz but without success. The following points have arisen.
1). The file was downloaded. OK
2). The file was extracted to the Desktop as Python-3.5.0a1
3). Using sudu apt-get install Python-3.5.0a1, the message 'file not found'. Why not!
4). Looking into the extracted files it seems that this is a source package and therefore cannot be installed as is?
5). Finally, using the bash command 'find' it could not find the above file either.
Can someone kindly sort this out for me.
Thanks.

hello Experts!
need some help here with python FTP. so what i'm trying to do is, from a linux machine, ill be sending over a python script to a windows machine via python ftp. that works fine with no problem. now, i want to execute that python script i sent remotely. im having trouble with that. here's my code to just execute the script:

p.s : please dont suggest other options such as python paramiko due to many network security reasons

Code:

ftp = ftplib.FTP("windows machine name")
ftp.login("username", "password")
ftp.cwd("where\\python\\script\\is kept\\")

ftp.sendcmd("python myscript.py")

but looks like it doesn't recognize that command. how do i accomplish this please?

For my cell phone, I used an app named link2sd with a SD card. Because the current 8GB card is filled up, I got a 32GB card to take its place. For the link2sd app, the SD card is partitioned into 2 partitions. First partition is formatted to fat32 and the 2nd one is ext2 format. What is the proper way to copy content of these partitions to the new card? Thanks in advance.

Unetbootin does not do it and nor does startup disk creator. I the forums are described other ways but too complicated for me. I did find this, with simple instructions

sudo aptitude install python-parted isomd5sum python-pyisomd5sum python-urlgrabber extlinux python-qt4 python-qt4-dbus tar


That command should install these packages but all I get is sudo: aptitude: command not found.

isomd5sum
python-parted
python-pyisomd5sum
python-urlgrabber

Does anybody know a simple way to make a Fedora live USB using ubuntu. I was planing to try their Fedora Workstation 22

Hello - This is my first interaction with Linux. I recently purchased a Raspberry Pi 2 and am running the full version of Raspbian. I intend to use the Pi as my PLEX media server however I have been unsuccessful in mounting my NAS. I've read a number of guides on how to accomplish this but have been striking out on all accounts. I was hoping someone could help me with what information I should be adding.

NAS - Synology Diskstation DS212j - 192.168.5.195
Linux device - Raspberry Pi 2 - Raspbian - 192.168.5.186
Router - D-Link DIR-655 - 192.168.5.1

I've been accessing the Pi via ssh on my MacBook PRO - 192.168.5.188

Thanks for any assistance you can provide.

Hi,
I made some little applications with qt creator and i wanted to run them on an embedded linux board (linux 2.6.24). To transfer the files i use a SD card. If i move the applications to "/bin" after having mounted the SD card and then "chmod a+x" them then i have no problem running them.
But if i mount the SD card and try to run the applications directly in the folder where i mount it i have an error : "Permission denied". Also when using the command "ls" i notice that if i keep the files in the mounting folder and try to "chmod a+x" them, the modification don't happen. They stay "greyed" and don't go "green". (I don't know if this color code is a standart for linux terminal but maybe this could help you understand the problem).
When mounting the SD card i use the command :
Code:

mount -t vfat /dev/mmcblk0p1 /mnt/SD

So the files are located in /mnt/SD.

Am i missing something or is it not possible to run something like that ?

EDIT :
I tried "mount -t vfat -o umask=0000 /dev/mmcblk0p1 /mnt/SD" to chnage how i am mounting the SD card.

Still "Permission Denied".

With "ls -l" i can see that the permissions are staying :
-rw-rw-rw-

Even if i try something like "chmod 777".

It seems to be a problem related to the fact that the sd card is formated as fat32 but it must stay like that.

Hello,
I am using my raspberry pi with Linux 3.18+ installed. I changed the default ssh port from 22 to 16022. This is my sshd_config file:
Code:

# Package generated configuration file
# See the sshd_config(5) manpage for details

# What ports, IPs and protocols we listen for
#Port 22
Port 16022
# Use these options to restrict which interfaces/protocols sshd will bind to
#ListenAddress ::
#ListenAddress 0.0.0.0
Protocol 2

PAM auth is disabled and I only login using password. Now, I checked the authentication log file: /var/log/auth.log. This is a snippet of what it contains:

How is this possible? Why is it showing these random ports for ssh?

This is what 'sudo netstat -nlp' gives:

Plus, I am accessing my machine from outside my home network. My router is configured to block all ports, except 16022, whose tcp traffic is forwarded to my raspberry pi. So I don't understand why the log file has these weird ports listed.

OK, so I'm really new at this. And I just figured out how to download google earth. But then when I went to open it, it sadi that my graphics card was insufficient to run the graphics. Soooooo

1. What the heck IS a graphics card? Is it a piece of hardware or software?
2. How do I find out what kind I have?
3. How do I update it?

Thanks! I don't know what I'd do without ya!

Hi all,

I have a device which has a Compact Flash card and a SSD. The file system is split so that everything except "/home" is stored on the compact flash card.

On the compact flash I am experiencing partition table corruption due to power loses when writing to the CF card.

One solution to this is to move everything onto the solid state drive, but as this is also flash memory - is the rish of corruption still the same as using the CF card?

Thanks in advance for any replies.
