How can I create a user group that restricts Internet privileges to only members in the group, then I will assigns certain applications to join the group for access to the Internet.
For example, I want only group net to have access to the Internet. Group net is then connected to:

I recently installed Ubuntu 9.10 and have been trying to set up a USB printer. I hit a problem which I eventually diagnosed as being the ownership of /dev/usb/lp0.
First, the symptom:
~$ cat Test > /dev/usb/lp0
bash: /dev/usb/lp0: Permission denied
The initial diagnosis:
~$ ls -l /dev/usb/lp0
crw-rw---- 1 root lp 180, 0 2010-03-23 21:39 /dev/usb/lp0
Notice the lp group? When I checked group properties, this group did not have any members - not even root! The default for CUPS (from the CUPS doc) is lpadmin, in any case, so not sure what lp is all about. In fact, the 'lp' group has ID=0, the same as the 'root' group.
I fixed it by doing this:
~$ sudo chown root:lpadmin /dev/usb/lp0
Then I noticed that /dev/lp0 and /dev/parport0 also had group=lp, so I also did this:
~$ sudo chown root:lpadmin /dev/lp*
~$ sudo chown root:lpadmin /dev/parport*
i've configured my pc using 'sudo pppoeconf' and it worked fine, but when i rebooted my pc and tried to connect using 'pon dsl-provider' it says 'Error: only members of the 'dip' group can use this command'.
I've added myself to the group and tried to connect but to no use.Im able to connect in windows without any issues.
just trying to learn linux here and have some comfusing moments.it is my understanding that if you own directories and files you maychange the group, ownership, and permissions on all of these as you desire.however, in my case I cannot make any changes in my setup on group, ownershipor permissions on any of my files or directories.get error message <operation not permitted>. I know as root you ar supposed tobe able to do anything you desire, however in my case I can go in as root andtry the same commands with the same results. it is as if I am locked out ofsystem as far as any changes are concerned.on my jump drive I have:

Now I have set up a terminal server at work, with Ubuntu 10.04LTS and Free NX terminal server. All works great, over all expectations. But I have some file permission problems. In the home folder I have mad a folder where files that all users should have full access to is put. The problem is that when a user puts a file there, only that user have full access to that file, other users only have read rights. How can I make it so that all files put in this folder have full rights for members in the group "staff"?

View 1 Replies View RelatedI have a group (GROUP) with a number of users. I recently added a new user (NEW). NEW is able to read but not write group files, whereas all the other users in the group can read and write to the group files. The permissions for the group files indicate that all members of group should have write permission -rwxrwxr-x
/etc/group indicates that NEW is a member of GROUP

GROUP:x:501:GROUP,OLD,OLD2,OLD3,OLD4,....,NEW

Don't know if it matters, but both OLD and NEW write to the GROUP files over an internet connection. why NEW can't write to GROUP files? Is there a maximum number of members in a group that I might have exceeded?
I need to create a group that has the same permissions as the users group. Can I have the new group be a member of the "users" group to inherit its permissions?

View 14 Replies View RelatedIs there any way by which one can give ownership while creating directories itself. It should be one command otherwise it requires root login to change ownership of a directory.
View 4 Replies View RelatedI've already done the following commands
Code:

I've logged out and logged back in, and I was successful in making it the default directory it logs in to. Still, afterwards I noticed that that when I use the list all commands "ls -l" it shows that root owns it and it also shows that I do not, by default, have read write execute over it, only read execute.

I am a Linux Noob of the major kind.I have an MP3 player that is owned by root. I have a SANDISK it in also. I can copy files to the player despite it being owned by root but I can't copy them to the SANDISK which is also owned by root. So what is suppose to be after the colon?How do I determine what that is if it is a directory?How do I change to root to change ownership if that is what I need to do?Is there an application that I can use to change ownership easy and what user do I have to be to do that.

I finally replaced my Windows with Linux.. However, I need to run applications and modify files that are on NTFS mounts. I am unable to change ownership, permissions, and groups on these files so I may modify them without having to copy. I have several times attempted to chmod, chgrp, chown, etc.. while logged-in as root user; however it is to no avail. The owner and permissions are still geared towards root. can I change ownership and permissions on NTFS files so I can modify them without having to convert/copy them over to ext4 or different file system?- Matbtw: I am using OpenSuse 11.4 and running Windows apps with VirtualBox (with Vista installation image). I still have Win7 on my computer (non-emulated) and I would like to keep some files on those NTFS partitions so when I occasionally need to boot into Win7 I can modify those files because Windows blows and doesn't support Linux.
View 5 Replies View RelatedI use Linux but have a computer with windows I use for gaming. It died and put the hard drive into another computer and used knoppix to recover my files. I looked at the ownership of the windows files and the owner is knoppix. Now I am concerned that ownership will not work on my new Windows computer (when I finish building it, that is). Since I don't get into Windows much I have no idea what those permissions should be.
If I copy them with owner knoppix can I even access them in Windows to change the ownership to whatever Windows will accept? If I change the ownership before putting them on a CD with knoppix, can I write the CD? I will have to use the hard drive on the new windows box so will not have access to the files later (unless I also copy them to my Linux computer for safekeeping). At least I know the ownership changes to make with Linux.
I`ve been given a project to design a program that will interface with a hardware device through the parallel port.And so far it`s not going go.

View 2 Replies View Relatedi have inherited a mixed bag of sorts: several xp users updating an access mdb with the BE on a lamp stack shared via samba. i have a backup device which gets mounted at: /media/disk... each client record (has) a folder by the companyname on the samba share, and all relative documents are placed there. when the backup script runs, it just copies newer or missing files.
someone has been renaming folders, and not matching the folder name to the related companyname from the mdb. so...the backup script captures and duplicates the data in the renamed folders. some client records also have periods in the name (not required from a data pov), such as 'Company Ltd.' instead of 'Company Ltd'. i can produce a list of company names as the folders should be found easily enough, but get a little stuck with the linux scripting.
i can easily remove and further prevent any unwanted punctuation in the company name on the client record, and create the correct folder name on the samba share with vba, but would also like to:
-for each 'client activity' folder on the backup device
-rename the folder by removing punctuation marks
or
-delete the folder if is a dupe
i tried: ls -al | grep '&' - it properly returns only those lines with an ampersand in the folder name, but returns all folders when i try that with a '.'.
what would be the easiest method to do the renaming? i thought if there was a way to change ownership of the mounted device, then the vba code (easy to write) would be simple.
OK - i just ran chown -R on the external device, changing ownership to (me) instead of root. didn't want to because it took too long, but can now use the MoveFolder method of the filesystemobject from my app to do the renaming instead of some sort of bash script (which i was dreading).
I have a text file that currently has around 150 000 usernames in it. I need to somehow group them into smaller groups of 1000 and then add that value into the DB. for example user xzy group 1 (hopefully the groups will be digits incrementing)

how to search for 1000 then assign them group 1 and then 1001-1999 to group 2 etc.
I've been tasked with fixing a Red Hat system that dies with a kernel panic during the boot stage:
Code:
EXT3-fserror (dev sda1): ext3_check_descriptors: Inode bitmap for group 4 not in group (block 67239937)!
EXT3-fs: group descriptors corrupted!

I can boot into a Rescue CD, but I'm a bit out of my element because I don't use EXT3 myself, and I've never had to repair a corrupted file system before.
I wish to create several different users for different members of the family. They should all have different menus, and they should not be able to access some programs, above and beyond just the normal root blocked ones. Any personal configuration files (eg, bookmarks, saved passwords, logins for other programs (IRC, MSN, etc) should also not carry over. One of them needs to have KDE enabled as default (as it looks the most like windows). I however, would prefer to have enlightenment enabled as default for me. Is this in any way possible?
