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 RepliesI have a user that can ssh to every computer on our network expect for one. I verified that it has to be the account by having the user ssh from a different computer. the results were the same.

the questions are always like these..i am okay with sgid and sticky bit.but i dnt know where to set default acl and other permissions.
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 user on my CentOS server who is not part of any group, just by themselves.
How can I give that user 777 permissions without affecting any other user on the server? I have chroot off, so I can see everything, but the user cannot write.
Do I use chown?
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?
i wonder, why nobody has written about it ...
How can i grant permission for files to specific user or specific group ??
Updated:
We have 3 groups: "g12" ("u1" and "u2), "g34" and "g56".
"g12" should only read the file.
"g34" should write and read it.
"g56" should have all permissions (rwx).
And others should not access the file at all.
I am trying to setup 2 individual FTP users. They should both have access to the same directory. They both need to be able to read/write into the directory. But, I want them not to be able to write to each other's files (e.g. delete, remove, rename, etc.).
So let's say the shared directory is: /home/ftp/shared/
UserA needs read/write access to /home/ftp/shared/. UserA should only have write access to his own files. UserB also needs read/write access to /home/ftp/shared/. UserB should only have write access to his own files.
It would be a unix box of sorts, but that is the only restriction. I could use whatever software. I am currently thinking pure-ftpd or vsftp but I am open to all ideas.
I was unable to change the permissions for root node and for other users also. WE have tried all the possibilities like chmod and chmod -R 777 filenem. But we are unable to change that.

View 2 Replies View RelatedThere are some user-space based NFS clients (e.g. NFS Client library). Can I bypass file permissions by using such client? code...
Client1 uses usual NFS client (kernel-mode based) and user1@client1 can read only file1, but not file2.
As I understand, client1 sends uid in nfs request, server1 do a permissions check based on the request data. So, I suggest this is possible to have a client2:
Client2 uses user-space client, and hacker@client2 knows uids of user1 and user2; If he wants to read file1 he can send uid of user1; if he wants to read file2, he sends uid of user2.
Is the scheme possible?
How can I mount a device with specific user rights on start up? I still have some problems figuring it out. I would like to mount the divide with uid=1000 and gid=1000. My current entry to the /etc/fstab/ file looks like this:
dev /var/www vboxsf rw, suid, dev, exec, auto, nouser, async, uid=1000
I'm struggling to understand an aspect of mounting and mountpoints with /etc/fstab. There is a large number of sites and threads that make recommendations using things like uid, gid, umask, and other options. These methods, however, which I've used, are file-system specific, useful only for filesystems such as (V)FAT and NTFS that allow them.My current situation is that I am mounting partition /dev/sdb5 in, let's call it /media/myMount. My goals:Mount this partition automatically upon boot using /etc/fstab...The partition should be fully accessible only to a specific user or group.What I've done is create the mount point in /media:
If user michapma were to carry out the mount, I believe it would work; however, I want the mount to happen automatically during boot. So, how can I achieve my user (or group) permission goals for this and any other such partitions using fstab?The manpage for mount has been helpful, but after reading many tutorials and forum threads, the only way I know how to do it is to have the user do the mounting or rely on the file-system specific options.
I have a few FTP users on my linux server(running vsftpd). They all have their own directory and can upload and delete files in that folder.Now, I was wondering whether it would be possible to create special permissions/rights for users. For example, I would like to make it so that certain users could not upload .exe files, or I want a certain user to only be able to upload image files (gif, jpg).

I am trying to run a cron job as an oracle user. I put the user in the cron.allow file but it still won't run. Other users are able to run a cron job though. I think it's the way the oracle user was created and I wanted to recreate it. However it owns a lot of other file systems as well as the database. Is there a way to recreate or reset the oracle account without impacting what is currently in place?

View 1 Replies View RelatedI want to simply mount an ext4 file-system onto a normal mount point in Ubuntu (/media/whereever), as read-writable for the current logged-in user, i.e. me.
I don't want to add anything into /etc/fstab, I just want to do it now, manually. I need super-user privileges to mount a device, but then only root can read-write that mount. I've tried various of the mount options, added it into fstab, but with no luck.
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.

Been running 64 bit fedora for a few weeks now and all is dandy. I have been having problems using Wine & Winetricks to install extra components. Wine seems to crash when ever i try to run something as a standard user. Run as root and the problem doesnt happen. Do i need to add some permissions to run under a standard user? With Winetricks, when i go to install any componet, after extracting and installing all files i get:
'Executing early_wine regedit c:winetrickstmpoverride-dll.reg
regedit: File not found "c:winetrickstmpoverride-dll.reg" (2)
Note: command 'early_wine regedit c:winetrickstmpoverride-dll.reg' returned status 1. Aborting.'
Now i have searched everywhere for these .reg files that are not found, havent found anywhere that can tell me where to retrieve these files.
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...
if lets say 'someuser' sftp's into the box what is he actually able to do?Looking at my tests he can browse any directory to which he has read permissions but is only able to delete files in /home/someuser, even if they are owned by root. On the other hand in any folder above /home/someuser he would NOT be unable to delete a file even if its chmoded 777. Can anyone please confirm these findings.

I want to host a public FTP on my server, but i cannot get it so that people can read and write but not delete ANYTHING from it.
I have tried:
chown root /home/ftpdir

but people can still delete the files in it, i have no idea what to do next. that's the only thing i can find on Google about how to do it.
the users are logging in with the same Account, i cannot make a new account for each one.
