Ubuntu :: Create A User Group That Restricts Internet Privileges To Only Members In The Group
Jul 19, 2011
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:
Code:
So far, I am using the gnome group policy manager that is standard with ubuntu but Its not working. It is possible that im misdirected and that I should use a firewall instead?

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 try to add a new user but got error (shown in title). Is it possible to create a new user and create a new group at the same time? Or should I create the new group first then the new user?

Is it possible to allow a group/user to execute a command, where one of the parameters of the command is a group as well? example that does not work as intended:
Code:
Cmnd_alias SU=/bin/su -l %group1 This example works sortof, it treats the "%group1" literally. I know I can list out the "/bin/su -l <eachuser>", but as you can imagine that is impractical. In this example, I want people in group2(not shown for brevity sake) to be able to su to someone in group1

After freshly installing Lucid Lynx and tinkering for some time to get everything just how I like it, I managed to somehow remove myself and all other users from all groups. Now, obviously, I've restarted and I don't have root privileges as I am no longer a member of admin group. So I am somewhat stuck. I've looked at this page: [URL]. But annoyingly, there is no grub menu appearing on boot up (unlike previous Ubuntu versions). So I'm appealing for your help to either:
a) Show me how I can bring up the grub menu so I can access ubuntu in safe mode
b) Show me another way of accessing the system with root privileges. (Would using chroot from the Live CD work? I just thought of that now so I'll try it).

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"?

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!
mount: error mounting /dev/root on /sysroot as ext3: Invalid argument
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 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
[code]....
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 have previously set up sudo via adding my name to the wheel group and then giving full privileges to the wheel group in the sudoers file. Now I choose to learn to limit that. Had noticed the most frequent use I have of sudo is to run yum update. This got me thinking, could I remove the wheel group privileges and add the following line in sudoers to limit the privilege to simply running yum, and furthermore, make it so I could run yum without a password:
## Allow root to run any commands anywhere
rootALL=(ALL) ALL
Troy ALL= NOPASSWD: /usr/bin/yum
I think that would in fact work (if I understood one of the pages here, it will work). However, upon further thinking I realized that in such a case then anyone sitting at my computer could then use yum, without a password, to install or remove any file on my system � probably not a good idea. As a result I have to ask, can I tighten the privilege even further such that the only privilege so given was to run �yum update� and nothing else? (for example if they ran �yum install� it would fail). If you can do it, how?
Last, I was going to limit the privilege, time wise and try wise, by adding the following to the sudoers file:
# Defaults specification
Defaults:Troy timestamp_timeout=0, passwd_tries=3
Will that really work to limit the elevated privilege so I don't have elevated privileges lingering about, or is there a better way to do so?

I have a number of users, categorised into various groups. I would like one of those groups ("developers") to be in the wheel group as well. I don't want to just copy the people from the developers group into wheel, because then when that group changes I'll have to change it in two places. Is there a way to specify that anyone in developers is in wheel, and have that be dynamic?

A bit of an oddity that I've recently run into with my storage folder in my system; it's a newly installed drive that I've set to mount at /storage. When I first tried to use it, programs that I used that attempted to write to it tossed Access Denied errors at me in their own way. Checking the permissions (at the Terminal, ls -l / | grep storage) showed that /storage was set to 'rwxrwxr--'--Owner and Group were given full read/write/execute, but Others could only read. However, my logon to my system is a member of group root. Why, then, with the above bits set, would I not be able to write to it? Changing Others permissions to rwx (and presumably rw would have worked out for me since I don't leave anything executable there) allowed me to write to it, but I don't understand why that would have been necessary. So far as I'm aware, the prior drive that was in my system--mounted at the same location--did not need this treatment.

I would like to create a bash script that creates a single group from all users in other groups.
I've been at it most of the day, and I think I'm making it too complicated. I have about 100 lines of code, and it's still now working the way I would like. I'm starting to trip over my own feet with the amount of if statements and variables.

I made a mistake on my friend's Ubuntu system when trying to get hard drive permissions right. I wanted to add a user to a certain group with usermod -G, but without realising I should also use -a, with the result that the user is now not longer in the sudo group. This is the only (regular) user on the system, which means I can not sudo usermod again to get it right. So what to do? The only solution I can think of is using a live disc to restore the group belongings, but I want to know if there's a quicker way. Also, I don't know what more groups the user was in. Is there a history? Or else, what are the default groups?
