General :: Adding User To A Secondary Group?

Sep 10, 2009

If user1's main group is genetics and one wants to add him/her to group biochem and to assign biochem as his/her secondary group will the following suffice ?

Code:

$ sudo usermod -G biochem user1

I would like for user1 to have genetics as the main group but also belong to biochem. When user1 creates a file, as he/she belongs to main group genetics, I assume the file will be owned by user1 and group owner will be genetics. Ideally files created by user1 should be accessible to users in group genetics(when permissions are tweaked) but not by individuals in group biochem. However, any files with group owner biochem should be accessible to user1 as he/she does belong to biochem as a secondary group. Would having user1 main group genetics, secondary group biochem fulfil this criteria ?

General :: Adding Users To Existing Group

Aug 26, 2010

I've been asked by my professor to add the list of users to a linux server (not sure of the OS type I think he said debian) but anyway. He gave me this script to add users.

Code: #!/bin/bash
# Script to add a user to Linux system
if [ $(id -u) -eq 0 ]; then
read -p "Enter username : " username
read -s -p "Enter password : " password
egrep "^$username" /etc/passwd >/dev/null
if [ $? -eq 0 ]; then
echo "$username exists!"
exit 1
else
pass=$(perl -e 'print crypt($ARGV[0], "password")' $password)
useradd -m -p $pass $username
[ $? -eq 0 ] && echo "User has been added to system!" || echo "Failed to add a user!"
fi
else
echo "Only root may add a user to the system"
exit 2
fi

I need to see if I can get this script to read a file that list the usernames and their passwords using the pipe command (or some similar command) so I can just do it in one batch. I've done some searching but there are so many vairiations of the code that I've confused myself. Also, I'm not too familiar with linux, it's been a few years since I've used it but in the prior script, I need to add the users to an existing group named "forensics". Which line would I change/add in order to do this?

General :: LVM - Adding New Disk Space To Volume Group?

Feb 7, 2011

I plan to install a server using LVM. I thought a partition schema where /boot would be in an ext4 partition while / /usr /var /home and /opt would be in the LVM. My question is: if I'm putting / into the LVM, is it necessary to divide /usr /var /home and /opt into different logical volumes? If I divide them, would it become harder to maintain when new disk space has to be added to the volume group?

Ubuntu :: Vino Won't Start After Adding Secondary X / Fix It?

Dec 3, 2010

I have recently added a second screen and uses separate X screens as my x screen settings. No xinerama. After adding the display Vino refuses to start. IIRC using dual X screens with xinerama works as expected.

Starting it manually results in code...

Is it even possible to use vino with two server-side x screens? I would be perfectly happy with only one X screen exposed via VNC if it is impossible in the VNC client to choose which X screen to connect to.

Server :: LVM Process - Adding Secondary HD As Logical Volume

Aug 3, 2009

I have a CentOS 5 server with a 250gb hard drive running close to the maximum space on one of the partitions. 87% of 200gb (/home), roughly. I have a second 250gb hard drive which is completely unused. I just recently did some searching through the forums here and found out about LVM and wanted to implement it. Although the downside is I believe it has to wipe a drive/partition before it can add it as a logical volume.

The process I'm considering following is:
1. add this empty 250gb (SDB) secondary hard drive as a logical volume on LVM and copy everything over from the currently filling up partition on my main hard drive.
2. have LVM add in the old partition on the primary hard drive (SDA)
3. extend my logical volume out to include the old partition. Extending my total hard drive space out to 450gb.

General :: User And Group Ids Scrambled When Using NFS?

Jul 11, 2011

I'm using nfs to mount the folder /mirror from a server onto a node.

This works, except on the node the user and group are displayed as "4294967294".

On the server: ls -al ./ displays

-rw-r--r-- 1 cu cu 0 2011-07-11 15:08 test1
-rw-r--r-- 1 cu cu 0 2011-07-11 15:08 test2

whereas on the node

-rw-r--r-- 1 4294967294 4294967294 0 2011-07-11 15:08 test1
-rw-r--r-- 1 4294967294 4294967294 0 2011-07-11 15:08 test2

I have usermod and groupmod the username cu to have the same numbers on the node.

On the server: id displays

uid=1021(cu) gid=1007(cu) groups=1007(cu),109(admin)

on the node

uid=1021(cu) gid=1007(cu) groups=1007(cu)

I'm stumpeed as to what the problem could be.

I should perhaps add that the home directory is /mirror/cu (so that the users share the same account when mounted). Not sure if thats relevent though...

My /etc/exports file (on the server) looks like this

/mirror *(rw,sync)

and I do the mount (on the node) with

sudo mount server:/mirror /mirror

General :: Understanding Ubuntu User / Group Permissions

May 20, 2010

I'm beginning to deal with more than one user on my system (it's a VPS serving some sites) and I need to make sure I understand how group permissions work. I have an account named "admin" .. it's basically the primary account that is used for serving most of the sites that I control myself. Now, I added a second account named "Ville" as one of my users wants to be able to administer that site. So, I can do this the easy way and just chown their domains folder under the ville user, they have permission to do whatever they need be and so forth. However, let's say I want to also give the admin user access to the files (modifying and all) .. how can I put both users into the same group and give them both permission?

I've tried doing:
sudo usermod -a -G admin ville
To add the ville into the admin group, but ville still cannot edit files by admin. Permissions for the primary directory for the ville user are read/write for both owner and group, and the current group for the files is admin:admin ..
But ville still can't write into the directory. So, what should I be doing here to get this right and secure at the same time?

General :: User Can't Access File That Is Accessible By A Group?

Aug 5, 2010

I Want to be able to let my girlfriend view my pictures folder while at the same time keeping my sister out. So I created a group "JessAndI" and made myself and her apart of that group. I changed the group of the directory recursively to "JessAndI" and gave the permissions to 770. She still isn't able to access or even view the directory unless i change the permissions to allow others whether it be 774 or 777. Am i doing something wrong? I've checked and double checked to make sure she is part of the group and the group is the group on the directory and all the sub-directories and files.
