i want to Restrict a particular user from creating a file beyond a prticular size.ie he should not be able to create a prticular size [say 10mb] but he can use upto 10 gb.[ not the quota space i mean]
View 6 RepliesI have a two hours long home video with I edited in a video editor program. I'd like to burn it to DVD, but first I need to export it to an mpeg file. Cinelerra doesn't allow me to render to mpeg, instead it offers .avi or .dv - problem is that the resulting file size is enormous. (i.e. 1 minute of .avi = 1.2GB! or around 500MB when I output to .dv) What file format would be best to render to and at the same time not to get an insanely big file? I'd like to keep it under 1GB if possible.
View 2 Replies View RelatedI'm researching about symbolic links been used with samba / CIFS:I'd like that the user that uses a MS-Windows OS could see my shared folder on CentOS 5 and the symbolic links that are inside this folder. Well, it works but, the user will see that the size of the file is bigger than the real file. Apparently, CIFS gets the size of the symbolic link (aproxim.32K) and add it to the size of the file.Example 1: 100KB file, used with shared folder, MS-Windows's user will see 100KBExample 2: 100KB file, used with symbolic link inside a shared folder, MS-Windows's user will see 132KB. (Sym link + size of file)Is there a way to allow the user only see the size of the file, and not the file + symbolic links ?
View 1 Replies View RelatedI was just testing specifying limit on file size to a user and have added the following to /etc/security/limits.conf bob soft fsize 100 This basically should have said not to allow bob to create anyfile greater than 100Kb in size.
But the interesting thing is, if bob already has any file which is greater than 100Kb in size, it even doesn't allow to log him into the system both from console and SSH. Also nothing is logged in logs.. How do I configure it so that, bob can login to the system even though he has any file greater than 100Kb (but doesn't allow him to create file which are greater than 100Kb) ??
I hope I am in the right forum. I have a question about restricting users from being able to change their own passwords in Fedora 10. In Fedora 6, I was able to do this by using passwd with -n and -x flags. If I would set the -n value greater than the -x value, then the user would not be able to change his/her own password. If I do this in Fedora 10, this no longer works
View 4 Replies View RelatedI have searched somewhat this forum but haven't yet found a similar post using the keywords I entered but perhaps there is already a similar post then please refer me to it.I am trying to add a user account "Guest" to allow people on my laptop without giving them access to vital parts of the computer. Basically, I want them to only be able to view their own home directory and access internet. Nothing more.I have set the group to "guest" and changed the other home directories of other users to owner access only.
Guest still has access to root and is still allowed to perform actions in various critical areas (deleting files from for example my Windows 7 partition). This I also want to prevent. I was thinking to set each directory's permissions to Owner and Group only and remove Others access.My questions:
1. Will this have any undesirable impact (programs of main user accounts not able to access certain directories)? For guest user I don't care as long as internet works.
2. When I start User Manager and disable for Guest all options except "access internet" (so I also disable access to CDROM), the guest can still access the CDROM. Does this mean the User Settings menu has no effect or is overruled by something?
I want to limit the amount of connections a user can make outside of the box per user group, should I be doing this via iptables or what? aka:
group1 can only have 2 simultaneous outbound connections
group2 can only have 8
I'm trying to restrict a particular ssh user to his home directory, I'm just giving him access so that he can ssh to another server that is only accessible from the former but restrict his movement so that he can't poke around the former.I already made some changes to sshd_config file and added the following line at the end:
Did some test, user joe can ssh to the server but unable to do anything aside from logging in, even a simple ls command will immediately close the putty session. I know I'm still missing something but don't really know what it is.I also tried this how to that uses rssh --> http://www.adamhawkins.net/2009/05/r...ured/#more-431 however when I login the session immediately closes.
I need to check the free available size on the "/root" before creating a file .
Can i do it by using df?if not , can you specify me which one to use?
Last weekend i have increased the open file size (ulimit -n) for the application user id i have update the limits.conf file with necessary inputs restarted the service and the server as well, when i check the ulimit value for the specific user by switching user from other user it shows the new value (10240) but if i login directly using the application id the ulimit value shows as 1024 which one is the default one.
View 6 Replies View RelatedWe set up a server with my friend (still newbies ) a couple of months ago using Ubuntu 10.04 LTS server edition and agreed to let some folks at school to use it to install drupal on it for teaching and learning purposes. So the idea is that there are multiple users that all install drupal in their home folders separately using SSH and continue from there on etc.
Everything is set up for that to work (domain, settings etc), but there's one thing nagging me, and that's how everyone can look at everything on the server. They dont have rights to modify anything but can look at file listings and view inside files etc.
So how do I restrict the viewing rights of users to inside their home folder, BUT so that they can use the cd command to go to folders inside their home folder, but not outside of it. As far as I know rbash purely keeps you inside home and allows nothing else, so that doesn't work, because you need the cd command.
i have rhel 5.2 and i want to create user using useradd command without creating user home directory and not throwing any warning/error about not creating any home directory.i have tried useradd -u "$NEW_UID" -g <gid> -d "/home/$1" -M "$1"where $1 is user name and $NEW_UID is i am calculating.it throws error as useradd: cannot create directory /home/$1which i dont want to come , how to prevent this?

View 4 Replies View RelatedI downloaded three iso-images, 1 dvd-image and 2 cd-images:
openSUSE-11.3-DVD-i586.iso
openSUSE-11.3-GNOME-LiveCD-i686.iso
openSUSE-11.3-KDE4-LiveCD-i686.iso
Being paranoid, I created iso-files from the burnt DVD-R and the two burnt CD-R to verify integrity.
The iso-file of the DVD-R was identical to the downloaded image. Both iso-files created from the CD-R were different in size.
The original size of openSUSE-11.3-KDE4-LiveCD-i686.iso is 719.323.136 Bytes.
I only got 718.938.112 Bytes when recreating an ISO-file from my CD-R.
The CD-R is from Sony. When the length of my ISO-file doesn't correspond to the downloaded one, the checksum file verification doesn't work.

I removed the account and deleted the group but it still shows up when I type in the address /home/xmbc
Is there anyway I can delete this file. It also will not let me create any new user accounts is there any way I can fix these prolbems without totaly reinstalling the system.

I have a requirement to create more than one user (one initial user with sudoer privs and one "user" user that has no special privs) upon installation of xubuntu 10.04 or 10.10 (doesn't matter). My goal is to create a "automatic" installation process with as little user interaction as possible through use of preseeding and remastersys so that all the programs and their configurations are set upon first boot. If this is not possible, (which I don't believe it is, but it's Linux!) then I think I can make use of a bash script that will run on first boot of the operating system and then delete itself so that it does not run again. My questions are:
* Is there anyway to create more than one user upon or during installation?
* If no to the above, how would I go about making a bash script that runs on first boot and deletes itself after being ran?
I am looking at creating two user accounts for "contract system admins"..These guys will be performing sys admin duties for a sever -- however, I am still concerned about security of data. For example, the server contains password information for our database, etc.Besides making them sign an NDA, etc. what other security mechanisms could I put in place to ensure that they don't just go buck wild. For example, when someone makes a sudo command, is this logged?
what are some recommendations for general security practices?
