Fedora Hardware :: Can't Write To Flash Memory. Automatically Set As Read-only

Jan 21, 2010

I used to be able to write to my SD memory card but just recently it is being automatically mounted as read-only. I checked the read-only tab and tried to set it to the lock position, and to the unlock position. Neither position makes a difference. It was working normally a few days ago. I also tried changing the permission using su

ls -lt gives the following result
drwxr-xr-x 4 col root 16384 1970-01-01 01:00 CANON_DC
chmod chgrp and chown in su mode don't change anything either.

I tried mounting a different 1GB SD card and it works perfectly. I noticed that when I mount this card I get a window asking me what I want to do, but I don't get this on the other card. It must some kind of setting related to the unwriteable card.

I am using F10 2.6.27.41-170.2.117.fc10.i686

Hardware :: PCMCIA Linear Flash - Read And Write To The Card

Mar 4, 2011

The card in question is a PC Card (PCMCIA) 16Bit Intel Series 2 Flash Memory Card (2MB) and I want to be able to read from and write to the card. I've rebuilt latest stable kernel (2.6.37.2) with all the PCMCIA options turned on or built as modules. I've got an SRAM card, a CompactFlash Card (in a CF to PC-Card adapter) and the Linear Flash card to try, the SRAM card I'm not expecting greatness from, but hoping to prove that the slot works (it registers, but doesn't get much reported from lspcmcia). The CF card in the adapter works. I'm expecting to see a block device in /dev but nothing appears lspci:

General :: Embedded Webserver (mysql) On A Compact Flash: Reduce Read / Write Operations?

Jul 7, 2011

I've developed a tiny webserver for home automation out of an ALIX 1D, and based on a debian lenny. It runs very smoothly and is now able to operate quite a lot of different equipment from a webapp. But i'm not sure how I should handle the compact flash, regarding read/write limitations. From what I've read the partitioning should be ext2, which would disallow the journalisation of the system. A utility to 'flatten' the repartition of write cycles exists, would it be relevant to use if the partition is ext2 ?

I will also disable all logging in execution mode (a debug mode will provide the logs). Is there any other parameters I have to take into account for maximum reliability (i.e. does the system randomly write in some files for various and potentially turned off purposes)? As for the mysql database, it's not important data, and it's actually reconstructed every time the server boots. Given this, is there a way to store the db in RAM rather than in a file? I'm not sure it's the right place to ask, but I sometimes see redirection to here from stack overflow.

Fedora :: Read & Write Share With NFS In 13

Jun 18, 2010

I can't see any option for recursive directories in nfs in fedora 13.

This is my set-up:

Code:

Code:

save and exit.

Code:

When i mount the directory /media/Data from another Fedora 13 box i don't have read and write permissions for each and every file. The -R recursive option would be handy unfortunately this option is unavailable. The red hat docs have not been helpful in this respect.

Code:

Code:

The mounted partition is of the ext3 type. With the nfs-3g type i don't have any issue however most of my directories/partitions are of the ext3 type so i need get it sorted.

I changed my user name id number to the same number on all boxes thus giving me write access. There must be a better solution than this.

Red Hat / Fedora :: How To Get Unlimited Read/write?

Oct 25, 2010

I installed SAMBA and SWAT, latest versions. What I want to accomplish is to give Windows users unlimited read/write access to the entire filesystem, eg. (/). Barring that, I'd like to at least be able to configure full access to individual directories.And by "unlimited", I mean being able to edit and delete everything that would be normally accessible only by the root user. I want to grant the Windows users of the shares access as if they were root users.

Fedora Security :: Cryptset - Can't Read Or Write

Jul 28, 2011

So I have just set up my cryptsetup.I can open/mount it by either "crypsetup luksOpen" or just clicking on the partition from the "Places" tab and it will ask me for a password and all.

The only problem is that I can't read or write to it at all. Everything is probably root, which isn't useful to me.

So how can I change it so that when I do either of those 2 methods for opening it, I can just fully use it, read and write and everything? As my user.

Fedora :: Mounting Windows Server08 From Fedora 8 With Read/write Permissions?

Oct 7, 2009

I have Fedora 8 and we just switched over from a Windows "File Server" to Windows Server 2008 (10.1.1.17). I updated my fstab file and now when I go onto the Windows folders, I can list and read files, even save them, but new files are always read only.

fstab file (some, without the asterisks):
//10.1.1.17/USERS/Jeff/fs /home/mriuser/Desktop/fs cifs rw,username=jsadino,password=**** 0 0

I've tried ntfs-3g, auto, ntfs, smb, some umask combinations, changing ownerships, changing permissions, everything I could think of, but still can't modify new files.

[root@localhost tmp10]# mkdir tmp2
[root@localhost tmp10]# cd tmp2
[root@localhost tmp2]# touch tmp
[root@localhost tmp2]# ls -l

Fedora Hardware :: Zune Not Able To Read / Write Music

Jun 30, 2010

After 10 minutes of trying to mount my zune, I finally got it, only to open rhythem box to find that I can't view the music on it, or write new music to it. (It does have music on it, nearly 30 gigs of music, its also assigned to my windows computer that I dont use anymore). Sorry for the file being a jpe, but the fedora forums seem to hate high resolution, full desktop, PNG screenshots, so I edited it down and made it a jpe.

Fedora Networking :: Samba Not Working On 15 - Read / Write Privileges

Jun 19, 2011

i have a windows xp machine with filesharing enabled and the shares set up and ready to go i have a laptop on which i did a fresh install of fedora 15 with samba and all the necessary packages to make the fedora machine a samba client to the windows machine.

my problem is that when i go into nautilus and click on the network tab it shows nothing not one single computer...the fedora machine doesnt even show up.....i have done all the tests i can think of and confirmed that the smb service is running, the nmb service is running, samba is allowed thru the firewall and all the computers are in the same workgroup..yet neither one can see each other even more frustrating is when i go to mount a windows share thru the terminal it shows a successful mount (as i type in the command hit enter and recieve no errors) BUT when i go into the mount directory and open the new directory i made for the samba share it shows nothing there not even when i go into the windows machine and add a file to the shared folder...PLUS for some strange reason the /mnt directory already had two empty files called "home" and "boot" already in it i have no clue what thats about but ok, then on the windows side i go into "network places" and click on "show workgroup computers" and the windows machine will show up but not the fedora machine.

these are the commands i have used to install and get samba working- "yum install samba system-config-samba samba-client cifs-utils" "service smb start" anyway until i can figure this out i have decided to start from scratch and erase samba from the machine completely and i am hoping that maybe some one can read all this and come up with some ideas...maybe there is just something i forgot when i was setting this up yesterday its possible i just went to fast and skipped a step again all i want is the fedora 15 machine to just be a samba client with read/write priviledeges

Fedora :: Mounting An Ext3 Or 4 Partition With Read And Write Access Using Fstab?

Jul 24, 2009

Anybody know how to make an ext3 or 4 partition start up at boot with only the owner and its group having read and write access permissions.I don't want 'others' to have folder access. This is what i have done. / etc/fstab:/dev/sdb5/media/Data ext4 owner 1 2 The folder starts on the boot since it has been allocated a folder as u can see. Next i changed the the ownership and the group ownership of the folder:chown johnny:johnny /media/DataThe problem is that other users can few my partition since 'others' have read access. How do i change that to zero access?

Fedora Servers :: Cannot Start Apache - No Read / Write Access To HTTP Files

Jan 14, 2009

I am trying to setup my webserver and I am trying to make a website to run under suexec but somehow I cannot start my apache it directly fails and SELinux is giving me errors and don't really know what to do with it, it is giving me some command to type but not sure if this will make my server less secure. The SELinux error is as follow:

Code:
Summary:
SELinux prevented httpd reading and writing access to http files.

Detailed Description:
SELinux prevented httpd reading and writing access to http files. Ordinarily httpd is allowed full access to all files labeled with http file context. This machine has a tightened security policy with the httpd_unified turned off, this requires explicit labeling of all files. If a file is a cgi script it needs to be labeled with httpd_TYPE_script_exec_t in order to be executed. If it is read-only content, it needs to be labeled httpd_TYPE_content_t, it is writable content. it needs to be labeled httpd_TYPE_script_rw_t or httpd_TYPE_script_ra_t. You can use the chcon command to change these contexts. Please refer to the man page "man httpd_selinux" or FAQ [URL] "TYPE" refers to one of "sys", "user" or "staff" or potentially other script types.

Allowing Access:
Changing the "httpd_unified" boolean to true will allow this access: "setsebool
-P httpd_unified=1"

Fix Command:
setsebool -P httpd_unified=1

I will write down how I did setup my server so maybe you can see a mistake I did. First I changed my Apache httpd.conf I added the following to it:
Code:
NameVirtualHost 192.168.1.2:80
<VirtualHost 192.168.1.2:80>
ServerName localhost
DocumentRoot /var/www/html
DirectoryIndex index.html index.html index.shtml index.php
</VirtualHost>

<VirtualHost 192.168.1.2:80>
SuexecUserGroup ulyaoth ulyaoth
ServerAdmin webmaster@ulyaoth.org
ServerName test.ulyaoth.org
DocumentRoot /var/www/ulyaoth/www/html
ErrorLog /var/www/ulyaoth/logs/error_log
CustomLog /var/www/ulyaoth/logs/access_log common
DirectoryIndex index.html index.htm index.shtml index.php
ScriptAlias /cgi-bin/ /var/www/ulyaoth/www/cgi-bin/
<Directory /var/www/ulyaoth/www/cgi-bin/>
AllowOverride none
Order allow,deny
Allow from all
Options +execCGI
AddHandler cgi-script .cgi .pl
</Directory>
</VirtualHost>

Then I created the username "ulyaoth" with the group "ulyaoth" as I specified with my suexec, then I created all the directories as specified in my httpd.conf and "chown ulyaoth:ulyaoth (dirname)" them to the right group and username.

Fedora :: Disable Write Cache To Usb Flash Drives?

How to disable write cache to usb flash drives, change its size or change umount timeout.

Fedora Installation :: Boot Prompt Information Read Automatically From Isolinux.cfg Without User Intervention?

Oct 4, 2009

building an install cd or dvd media that will automatically install the Linux software on a client pc. There is no network connectivity so the client can only be loaded with Linux from CD or DVD media. The crux of the matter is that I can not automatically install the Linux software on client WITHOUT typing linux ks=cdrom:/ks.cfg at the boot prompt.

I want to avoid any user prompts and just have the software install with the RPMS that I need for this client pc at the boot prompt. Actually, when the boot prompt commences, I would like the software install to start with no user intervention. I've tried several different methods in isolinux.cfg, but the OS always wants boot prompt for the cdrom. Can the boot prompt information be read automatically from the isolinux.cfg with out user intervention? I'm looking for the same behavior as a LIVE CD that kicks off with no boot prompts after a few seconds. Here's a copy of my isolinux.cfg

default linux
prompt 1
timeout 600
display boot.msg
F1 boot.msg
F2 options.msg
F3 general.msg
F4 param.msg

Red Hat / Fedora :: Format For Server & RAID Setup For Multi Platform Read/write/access?

Jun 23, 2011

I'm looking to set up a server with attached mass storage device and tape autoloader to run linux. It's set up under Windows at the moment. Goal is to have users, connecting from individual workstations and laptops, backup their data to the linux server. On their personal machine, some users run linux, some MacOS, some Windows. I plan to set up the 5 500 GB drives as RAID5. I understand that if setting up as software raid the format is "physical volume for RAID". Under this setup, will Windows users be able to read/write and function as expected? I can't assume only linux user access.

Ubuntu :: Read And Write To USB?

Jul 18, 2011

I did install QLandkartGT and the plugin to use Garmin with it and it looks like it work, but when I do press "Live Log" I get the error message; "Device Link Error. Failed to request real time position. Realtime thread failed. Failed to configure USB: could not set config 1: Operating not permitted".

I also get a similar error when trying to download tracks; "Failed to download tracks. Failed to configure USB: could not set config 1: Operation not premitted".

My guess is that Ubuntu do not allow programs to use the USB port, so my question is how I do allow this program (or all) to use the USB ports.
