I have installed tftpd on Ubuntu, but I think it not secure very much. So I read its manual, and it says: The server should have the user ID with the lowest possible privilege. I find the server has the root UID:

I want to add 50 new users, not on the server yet I want to add them all to group Accounting - with 1 option, not user by user I want to setup a default password for them all, and have it say something like 'You must now change password or no access will be permitted' Any other options I also want to do once, not for each user?

View 3 Replies View RelatedI'm looking for a Linux command that can change ownership of all files belonging to a given user,preferably in a targeted directory, to another specified user. My dream command would look something like this. chuser -R --olduser tom --newuser jerry
This is my scenario... I have a backup file (.tgz) with user and group information preserved in it. It was taken from a web server running Apache and MySQL. The files in the backup are from across the system and contain files from several different users and several system type accounts and it is key that when restored on the new server the settings are not lost. The problem is that the users on the machine the files are being restored to don't match the ones in the backup file. For instance both machines had a MySQL user but they have different user ids and there are several user ids that existed on both machines that belong to different users. This means there is no way to sync the users on the new machine to the ones on the old machine. I can find all the users files with the find command like this...
find /decompressed-backup-dir -uid 1050
or
find /decompressed-backup-dir -user tom
If, as I suspect, there is no way to do what I want with a single command then perhaps there is a way to pipe the results of the find command to another command to handle the ownership change?
I could do this with a PHP script but there are 4GB and tens of thousands of files in the backup so I don't want to use PHP or Perl but I would be happy with a shell script that could handle it.
I have a uid that I need to change however I need to know the process of doing so as this user is a vital user that has ownership of several running pids on this server. (webserver)
This user (admin) has a uid of 1003 on this server (server-A). However, on all our other servers (server-B-G)the uid is 1001. The reason for changing the uid is that the nfs mount that is mounted on server-A and on all the servers does not work right due to the uid difference. We have diagnosed to this point.
My question ... admin is the owner of several running pids.
So in order to change the uid, do I need to:
- stop ALL pids owned by admin
- >usermod -u 1001 admin
- then start back up the jobs that admin runs
I have verified that there are no files/dirs owned by uid 1003 but the ownership is admin.
I can run a find >find / -uid 1003 - to locate any orphaned files/dirs before I start back up any jobs that require admin ownership.
Then >chown the file/dir.
Does this appear to be a viable plan to get this uid corrected?

View 4 Replies View RelatedFor a user on a Linux host, I need to make everything inaccessible besides his home directory. I have heard that this is usually done by changing the root directory for the user (and setting it to the user's home directory), however I couldn't find the way to do it.
I thought about the chroot command, but it seems it just runs the specified command, considering the specified directory as the root directory. So it seems chroot is not what i need. So my question is: what is the command which changes the user's root directory?
I want to know how to change a password to an user account. Can someone give me the syntax on how to do this? I was using usermod but it's not working (usermod -p 123456 user1). Is there other way beside usermod? I am using RHEL5.
View 3 Replies View RelatedI've created a set of users using the newusers command. Unfortunatelly ive messed up and added all users to the 1000 group as primary group instead of giving the group argument as null what would add them to a new group. To make things clear:
The entries should be
user:password:::User Name:/home/user:/bin/bash
but I did
user:password::1000:User Name:/home/user:/bin/bash
I need to create the missing groups. A simple fix could be do a for loop creating a group with the name of each user in my file and then adding the users to it. Are there any dangers of doing it? What impact could this change have? Are there any safer ways?
A combination of the following commands:
Quote:
Add users to a group with the gpasswd command:
# gpasswd -a [user] [group]
To delete existing groups:
# groupdel [group]
To remove users from a group:
# gpasswd -d [user] [group]
If the user is currently logged in, he/she must log out and in again for the change to have effect.
Quote:
for i in (names)
do groupadd $i
gpasswd -a $i $i
Assuming I've created all users in group 1000 I could remove them from it with
Quote:
# gpasswd -d [user] [group]

Starting from the operating system to the programs all was backed by a closed company.EurekaAt the year 2004, I have read a magazine that mentioned the word "Linux", it was the first time I got to know that actually there was other Operating Systems than Windows. I "googled" and "wikipped"(searched), all the information I could get about that new system(for me).
After few searchs the word "Debian GNU/Linux" came up. I have burned the ISO file for a brand new CD and got all enthusiast.ExperienceI had actually complete the command line install, but always thinking for myself "What a waste of time!" (Yeah... such an idiot I was at that time).
After the installation, I booted the distribution and at the minimal error and/or thing that didn't worked like I pretended, I would just say a lot of terrible things and give up.The second chanceOnly at about 2007, I gave Linux other chance(ironic, like Linux was the guilty for my lack of skills. I downloaded and burned the Ubuntu Linux 6.06 Live CD ISO.
I was astonished when the CD booted,
asked for language and actually changed it.
Then the Live Environment "flashed"(appeared).
I was out of words and almost regretted everything I have said about Linux efforts(I still didn't had a open mind tough). For the first time I actually faced-up the problems and issues that came up, but annoying everyone and saying bad stuff(I'm terribly sorry).The enlightenmentOnly at about end of 2009, I started actually wanting to learn how everything worked. That was the time I changed for Slackware Linux distribution. I learned many stuff. But with the time, I realized that the important isn't the Operating System and/or Distribution we use, is the use that we make of it. Nowadays I use about any distribution without complaining much. We need to respect the work of others after all, and we can learn with the mistakes too.
All this to askThe questionDo you think the registration of Linux users can make people, companies, governments, institutes, and everything related to technology change their opinions (minds)?NOTE: This reflects for BSDs, OpenSolaris(now over) and all other related open source software not just Linux.

I have this dump script that performs either full or incremental backups depending on the day of the week. From what I have read, when using dump you should drop to single user mode to help prevent the backups from being inconsistent before you issue the dump command. What I want is the script to drop to single user mode, perform the backups using dump, and then go back to runlevel 3 after the backups complete.
I know when you enter init 1 to drop to single user mode, but doing so within a script reboots the computer and drops it to single user mode and the rest of the script doesn't complete.What would be a good method for me to be able to accomplish what I want to do? Do I need to run other scripts that would call mine?I am running Centos 5.4
I need to edit the system time as a not-root user. I am carrying out the following actions in my program.
1. Read the User Id of the process. User_ID= getuid()
2. Printing Capabilities(Permitted, Efffective, Inheritable)of the process
3. Setting UID = 0, using setuid(0)
4. Calling the prctl(), function to keep capabilities
5.Switching the UID from root to User_ID of the process
6. What we have now is a process with root capabilities as a non root user
7. On printing Permitted, Effective, Inheritable capabilities, I get the following
--> Permitted = 0xfffffeff = Effective
Inheritable = 0x0; with UID = 1001;
8. I then try and set the system time with --> system("date -s 10:00");
9. I get an error: date: cannot set date: Operation not permitted
10. I am unable to understand as to why I cannot set the time even thought the capability bit CAP_SYS_TIME in the Permitted and Effective sets are SET.
