What are the possible problem when Windows access the file from Ubuntu got Read Only even though have a full permission to read, write and execute the file? Ubuntu to Ubuntu accessing the file there is no problem only Windows got a problem.
View 1 Replies View RelatedI'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.
I own a particular file on a Linux system. I would like to give 2 groups (accounting, shipping) read access and only read access, and 3 users(Mike, Raj and Wally) write access and only write access. How can I accomplish this?

I have apache2 running on my computer. I want to change the permissions for /var/www/ so that I can edit the files without a problem. Right now I can use the gksudo command, but I'd like to be able to have all the files available when using an IDE like eclipse.
I've read in several places that
Code:
chmod 755 /var/www
will do, but if I'm not mistaken that would give read/write access to anyone. I'm not in a production environment, so I'm not too worried about security, but I'd like to give anyone else as less permissions as possible. Would this be possible?
I'm using Arch right now and i'm having problems syncing my ipod with Amarok (KDE).

We have a xfs partition over a hardware RAID that stores our RAW HD Video. Most of the shoots are 50-300gb each so the linux cache has a hit-rate of 0.001%.

View 4 Replies View RelatedI have a text file that contains a single word and I want to write a bash script that will read the word from the text file... The following is my incorrect attempt, as it assigns the name of the textfile to the variable as opposed to the word stored within the textfile:(assume I have a text file value.txt that has its contents a single word, say wordone)
Code:
#!/bin/sh
for f in value.txt

so the output of the above script is value.txt, however I want it to be wordone.to summarise: how do I assign the value of the word contained within a textfile to a variable?
I want to simply mount an ext4 file-system onto a normal mount point in Ubuntu (/media/whereever), as read-writable for the current logged-in user, i.e. me.
I don't want to add anything into /etc/fstab, I just want to do it now, manually. I need super-user privileges to mount a device, but then only root can read-write that mount. I've tried various of the mount options, added it into fstab, but with no luck.
I recently installed Ubuntu 10.04 using Wubi on an ACER Aspire 5000 XP laptop. Everything runs ok and I can access my Windows folders from Ubuntu through the host directory but only as Read Only.

View 5 Replies View RelatedAnybody 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?
View 1 Replies View RelatedI have installed Ubuntu 11.04 64 bit desktop version on ext4 partition without swap. I have maximus iv extreme motherboard with 8 Gbytes RAM. Using 3 internal ntfs formatted hard drives and 3 external ntfs usb 2.0 hard drives.When I am trying to copy or move files FROM or TO any ntfs partiton it is 90 percent chance it is going to freeze.For copy/moving files I am using krusader run as ROOT or as user without root privilege or Nautilus as user without root privilege. It wasn't possible to switch to another terminal - it simply does not react on keyboard or mouse input and only hard reset is possible (scares me because of ntfs disks)From this point of view I have suspicious on ntfs driver but:I am completely beginner in linux and I am looking for help to navigate me how to investigate to find what is causing the problem eventually to solve it?
According to my experience it seems to does not matter if hard disk is internal or external connected through SATA II or SATA III or USB 2.0. I have tried to manipulate with ntfspartitions through the vmware or virualbox or truecrypt software or just do a simplecopy/move files - it have has always the same results - freeze. There is not possible to say how long it is going to work properly and when it is going to freeze - sometimes it's working hour, sometimes it's working couple of seconds - no matter if it is read or write operation/s within ntfs partition.
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.
I'm setting up Ubuntu Karmic on my sister's old computer for my nephew, he's quite young so my sister asked to install some content filtering. I'll first setup an OpenDNS account and I've installed and managed to get dansguardian and squid working on a virtual machine to try it out. so far it's working pretty well, but I need to secure it form the inside out.
I was thinking of blocking specific outbound ports so he could not bypass the proxy. because by default the firefox configuration can be easily changed. so I have a couple of questions.
1. is it possible to block outgoing ports on Ubuntu?
2. is that the best method?
3. is there anything else I should be aware of to prevent subversion?
lastly, this question is probably unrelated to this board but I've set up a cron job to update a dynamic ip with OpenDNS, the problem is that the password is in clear text in the user's crontab, can I play with permissions? is it possible to run the job under a root account and deny read/write access to a normal user?

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.

I've hit a wall here; I'm attempting to find some way by which to view files and cd into directories on a device mounted read-only. So I need the permissions to read, write, execute (and the same with directories), but chmodding is out of the question because I don't want to alter the drive one iota.
I guess what I could do--what I was thinking of initially--was to dupe the whole drive and then mess with permissions. This wouldn't affect the original (actually I'm working on a duplicate of the original, but I'm treating it as if it were the original) but I was hoping for something that would maintain data integrity. This is a forensic application and not altering the data is very important.

View 3 Replies View RelatedI've been a Xubuntu/Ubuntu/Lubuntu hobby user for about 18 months now. I started using Linux as a way to revive older computers provide a backup and expand my knowledge of computing. The command line was something new to me but as long as I can find detailed directions on how to do what I want I can usually manage. I set up a Samba server for my home shared network and now I'd like to make the shared drives of that server accessible from outside my network. Via ssh or ftp or some program of the like. I'd like to have it user name and password protected. Configurable user rights would be nice. (read/write/delete/etc) As well as novice user friendly.
My end goal is a server with read/write capability that I will be able to access from work or a friends house or anywhere with an Internet connection and my laptop. I understand about port forwarding and have done so with my home network behind an AT&T U-verse router/modem. I've researched openssh and some ftp setups but they seem like they can be difficult. Now for the questions. Is this task something that can be accomplished without a degree in computer networking? Is there a program(s) that would make this a simpler task? Is this more complex than its worth? How would I go about setting up such a thing?
