I am running Ubuntu server with an SSH server installed. How can I create an ubuntu user and give that user permissions to read and write only 1 specific folder so someone can log in through SSH using the new username and only put files in the folder I specify?

Is it possible "reset" all (X, GDM related) permissions/settings of one user? What would cause one specific user not to be able to log into anything via gdm/the login screen? After providing the proper password, the screen goes black and then jumps back to the login screen. No session alternative works, not even xterm or gnome failsafe. I can however log in via the console (Ctrl+Alt+F6, recovery etc). With another user I can log in via GDM just fine, and deleting and re-adding the "broken" user doesn't make any difference.
Some (maybe) relevent logs:

I want to make sure that the user www-data cannot be used to login on my system (Ubuntu Lucid). How can I find out? - is there a command I can run against this user? (traditionally run by Apache daemon)
View 3 Replies View RelatedI have a minor issue with permissions. There are a couple of devices that I need r/w access to in /dev. Whenever I first boot up and log in as end user (not root) and I need to access the devices permission is denied. Logging in as root there's no problem accessing these devices. However as an end user every time I need the devices I have to first su to root to change R/W permissions (chmod 666).
Now, the good thing is that the permissions stick even as I logout and then log back in, but as soon as I reboot my computer (every night) I have to go and chmod manually. I'm trying to find a way to avoid having to su and chmod manually but I'm not having much luck. The devices I am trying to access are /dev/ttyS1 and /dev/windrvr6, when I first boot up and login as end user the permissions look as follows:
crw-rw---- 1 root uucp 4, 65 May 27 04:11 /dev/ttyS1
crw-r--r-- 1 root root 253, 0 May 27 09:12 /dev/windrvr6
After I edit /etc/group and I add a user to groups it didn't belong to, the user will not be able to use it's newly acquired privileges unless it starts a new session. Is there a command to refresh user/group properties in an ongoing session?
View 2 Replies View RelatedIn my /var/www directory, I have everything set up with:
user: www-data
group: developers
directories: chmod 570
files: chmod 460
Everything seems fine. Users from the developers group can edit files and all, but now we began using the Git repository, and whenever a user edits a file (ie. Joe who is a developer,) file permissions get screwed again. Now they're:
user: Joe
group: Joe
directories: chmod 755
files: chmod 644
How can I fix this so permissions remain the same?

I have a web server running Ubuntu Maverick Server Edition. I changed the /etc/motd file to something custom (some awesome ASCII art). This changes the login for every single user on the entire system. My question is this: Is there a way to change that login file and make it different for each user or is that the only file and it can only be done system-wide.
View 1 Replies View RelatedI wrote a little script that will automatically mount two Samba shares to my home directory and I was wondering if a) You guys/gals had any input as to how I could improve on this script and b) Tell me how I would go about having this script automatically execute when I log on via SSH.
Code:
#!/bin/sh
mount -t smbfs -o username=Myuser,password=Thepassword //192.168.1.102/Data1 /home/user/Data1

I'm seeing really bad user login format under a standard installation and am wondering why ubuntu does this as default. I have noticed that the graphical login for gnome sizes itself to accommodate a user's exact password length. This indicates to me that somewhere on the unencrypted part of a standard installation with user encryption contains at least some indication of the content of the password length which seems a security flaw even if not a complete hole, it majorly reduces the number of attempts a cracker would have to cycle through.
And that's assuming that *only* the length is contained. Furthermore it seems that it would be MUCH better to simply display the number of characters entered into the pw field and allowing the gui to expand itself from an fixed size as the field is filled out so the the user still receives visual feedback for entering characters. Either a simple character count display should be entered into the field or a 10 dot to new line so that one can visually quickly count the number enter by multiplying from a 10base graphical observation.
I am using the sudo command to log on locally as another user by the following command:
sudo -u theotheruser -s
or
sudo -u theotheruser sh
As I see it, this initiates a new shell with the mentioned other user.However, this doesn't load that users profile from his home directory.Is there a way to automatically read the users profile when login in with selected command? I am mostely interested in getting a working prompt when logged in.

What does Set user ID do? Reason I ask is if I select "Set group ID" it makes it so any files/folders created within that directory get the group accordingly. But if I select "Set user ID", it doesn't do anything that I notice. I thought maybe it would change it so any files/folders created get that user set as the owner. So if that's not it - what's its purpose?
View 2 Replies View RelatedI just started dual booting Ubuntu 10.10 on my mini 10v with OS X a couple days ago, so I'm still pretty new to Linux.
But anyhow, I was attempting to change my User ID number so I could access the files in my User folder on my OS X partition. So, I tried entering the following commands:
sudo usermod -u 501 yourusername
sudo chown -R 501 /home/yourusername
Of course, smart me should've realized I should've been logged out and on a different administrative account to do this. But I didn't, and I believe the second command didn't work. So, whatever, I thought I'd try logging out and logging in as root.
So, I logged out, tried logging in as root, and of course, no dice because I didn't know the password. So then I tried logging onto my account and upon logging in, I got two errors. One was about ".ICEauthority" and I didn't keep track of what the other one was.
Great. So I did a quick google for the error, then tried entering these codes:
$ sudo chown user:user home/user/.ICEauthority
$ sudo chmod 664 /home/user/.ICEautority
$ exit
[Code].....
And again, I think the last one didn't work. So, I looked up how to login as root, changed the password and logged in as root successfully. Then, whilst in root, I entered:
/usr/sbin/usermod -u 12345 joeuser
/usr/bin/find / -user 701 -print | xargs -t chown joeuser
/usr/bin/find / -user 701 -exec chown joeuser {} ;
Upon entering those, I logged out and logged back into my account and everything was a complete success. No error messages anywheres AND I could access the files in my Mac user folder.
So, here's my question. How can I make sure I have all the right permissions I need? Or do I already have the all of the permissions I had before changing my user id?
Did those last three lines of code I entered "override" all of the codes I had entered previously? I just want to make sure verify I have all the correct permissions necessary so I don't run into any issues later on.
How do I add root permissions to my user account?
I want full permissions for all computers in my house, without having to get up and go to the other room and change permissions for the file, then go back to the other room again.
I just created a partition, as THIS user, THIS machine, rebooted, and cannot create a folder on the partition I just created. UGH. No more of this stuff...
How can check that I have full permissions on anything should I set my self as root? There are a lot of files it said your not the owner so you can't change but if I'm not the owner then who is?

I'd like to set up my PC so that it has one "master account" for system settings, desktop appearance, etc. And then I'd like other user accounts that read these settings so if I change the settings on the master account, those accounts follow the new settings but cannot change them. But at the same time, these accounts cannot be allowed to read to master account's personal files (documents, music, etc.) Each account would be restricted to its own home directory, as expected.
Is there any way to set something like this up or am I dreaming of the impossible?
I have just installed Ubuntu on a machine at work and wondered how i can add a new user with the same permissions as the "main user"? I added a user via the "users&groups" gui but sorting permissions looks tricky.
View 1 Replies View RelatedI'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?
so i have a limited user (my dad) on Jaunty who has no write access to his floppy disks. Nautilus gives a permission denied error, and i discovered that root owns the floppy drive, thus allowing his read-only. (that write tab on the floppy in on btw). However, when i login as a admin, nautilus says that user has write access. ??? I check the user's user privliges and everything exept "administer the system" is checked. I can copy files on it by logging in as root.
View 4 Replies View RelatedI want to add my daughter as a user and give her full permissions to all the same folders and files that I use. I have given her permission to folders and their sub folders however she doesn't have rwx on the individual files within the folders. What is the command line to set this up?
Also with the command;

what is the -R for and when do I need or not need it?
I tried to place a mono icon in usr/icons/etc but I didn't have the permission to do so. I tried to change my user profile to Admin, thinking I could go back to custom, but that hasn't and it isn't allowing me to go back to my previous setting.
Within minutes of being an Admin user I noticed I couldn't even unmount something. I really need to figure out how to change my profile back to default.
After that has been dealt with, I would like some guidance on how to gain root access to put my icon where it needs to be.
I'd like to add essentially an anonymous user, which does not require a password. Second I think it's probably a good idea to only give this user very limited permissions, is there a way I can restrict the commands that they can run to a list (i.e. they should be able to run scp, ls, cd, maybe a few more, but not much)?
