Server :: FTP Permissions For Several Groups?

Aug 1, 2010

I have a FTP server (vsftpd), and would like to setup different file permissions for different groups:

-"ftpusers" group should only be able to browse and download.

-"ftpadmins" group should be able to browse, download, AND WRITE (RNFR, RNTO, MKDIR....).

Let's say my main directory is /var/ftp/docs/. It should be accessible by "ftpusers" group, but only writeable by "ftpadmins" group. Other groups or users may not access it. Which permissions and ownership should I give? My problem is that the dir can't be owned by two groups...

Server :: File Access Permissions - Working With Groups And Users?

Sep 15, 2009

Having set up many windows servers with complex permissions on shared folders, I now have to do the same in Linux (and I'm such a noob to Linux) I understand that each file/folder is assigned a user + group, and that the rights can be set for the user, the group and global (aka everybody else) My challenge is this, inside my shared folder there is a folder that should be RW to some users, READ ONLY to others, and not accessible at all to the rest of the users. (lets call the folder MyFolder ) All 3 groups have more than 1 user, so they have to be groups (right?) How would this model work in Linux ? If there is no other way, I guess I can nest the MyFolder in a folder that has permissions to allow all users that may access MyFolder, and block the rest, then on MyFolder, set owner group the RW users, and set global to READ ONLY.

Ps : The server I'm setting up runs Debian Lenny, files will be accessed from windows workstations using samba.

Fedora :: Strategy To Set Up Groups And Permissions

Nov 12, 2009

I'm setting up a Fedora 11 server for the company of one of my friends. So far so good. But now he has asked me to setup access restrictions to folders through samba. Now I'm quite familiar with user access policies, even though I'm quite new to the GNU/Linux world. What I want to know is : what is the best way to give and remove, on the go, rwx access for a specific user to a certain folder in a linux system? Can I create groups for each folders, whose members will have the given permissions? Or do I have to create users for each folder and add to their group the user witch i want to give privilege to?

Security :: Setting Permissions On Different Groups?

Nov 26, 2010

We are a school and we share a samba folder with students and teacher groups. What we are trying to do is:

- Give students group users the permissions to rwx own files in folder

- Students must not be able to do anything with others files. I mean nothing so, at most, they could see the files in folder but not read it.

- Teachers can do anything with files in folder

As you can imagine, the idea is that students deliver their exams in that folder without the ability to read/copy the other students files. With sticky bit we can restrict students permissions to their own files, that is ok, but how to restrict all the permissions on other students files without restricting student access to that folder?

Debian :: Users / Groups Setup And Permissions

Jul 13, 2010

I am used to setting up users and groups on my daughters computers with Ubuntu installed.
user: magz (daughter)
user: nigel (me)
group: nima

We each have our own folder for files i.e. magz and nige. This has always worked well and it didn't matter which user is logged in we could create and access files in the other users folder with full permissions.
root@nbsq: /media/2xfi/files# ls -l
total 8
drwxrwxr-x 9 nigel nima 4096 Jul 13 09:45 magz
drwxrwxr-x 3 nigel nima 4096 Jul 13 09:45 nige

I have finally got around to getting her to try Debian which I always use, however I have never had to set up users, groups etc in Debian (squeeze) so I just did what I'm used to with Ubuntu. What I've found is that if I create a folder while I am logged in then that folder cannot be accessed by my daughter when she is logged in and the same applies if she creates a folder then I cannot access it when I am logged in, unless of course I use terminal to change the owners. In each case with the new folder the owner will be: root and the group will be: root. I would have thought what works for Ubuntu would work for Debian, however there must be differences.

General :: CGI Script - Groups And File Permissions

Jun 6, 2011

I am having problems with groups and file permissions. I have a file owned by myself

Code:
-rw-rw-r-- 1 diblemar users 2.1K Jun 3 06:02 /cluster/shared/Injects/1404_1405_1000033606_79964.return.xml

I want to modify the file using a cgi script running on an apache server (on the same machine). Both diblemar and apache are in the same group.

Code:
apache:x:48:diblemar

However, I receive a file permissions error when I try to modify the file. I assumed that with the permission settings above apache would be able to modify a file owned by someone else in the apache group.

General :: Setting Permissions For Specific User And Groups?

May 25, 2010

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.

Red Hat / Fedora :: Users In Multiple Groups And File Permissions?

Feb 12, 2009

this directory has permissions 750 and is owned by user1 and group user1 I have an admin user that is primarily a part of group admin, but also a part of group user1 what would stop admin from having read and execute permissions on this directory? I'm running clamav and have a clamd daemon running as user admin (I could run it as any user, and I may make a special user later, but I don't want to run it as user1, user2, etc).

I have 2 (technically lots more, but let's just say 2 for now) users, user1 and user2 that have home directories /home/user1 and /home/user2. each is owned and group owned by user1:user1 and user2:user2 respectively with permissions of 750. my admin user is part of groups admin, user1, and user2 I need this to be able to scan my user's directories using the command (is this correct?):

clamdscan --move=/files/quarantine/ --config-file=/etc/clamd.d/adm.conf /home/user1/file

doing this gives the error:

/home/user1/file: lstat() failed. ERROR

If I change the directory permissions to 755, it works fine.Or if I leave the permissions 750 and change the directory group ownership to admin, it works fine. So, why would this be? Obviously it is a permissions issue, but why is it not reading admin as part of the user1 group and allowing the same permissions as it does when making the directory group-owned by admin?

Slackware :: User Permissions/groups To Access USB Scanner?

Jan 17, 2010

Slackware 13 64 bit Hp Photosmart c4280 USB (All-in-one)

- Printer successfully configured using CUPS

- Scanner only works when I am Root.

- When trying to access scanner as user it says there is no scanner attached.

What should be the groups for this user in order to access the scanner? Actually, they are: haldaemon, disk, audio, video, cdrom, plugdev, power, scanner, lp. Below are the outputs for sane-find-scanner (as both root and user), although, since the scanner works well under root, I am almost sure it is a problem with setting permissions and groups.

Quote:

# sane-find-scanner
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.

General :: File / Folder Permissions And Groups On Linux With Apache?

Jun 26, 2010

I'm trying to learn about permissions on linux webserver with apache.Some clues to the system: The server I have to play around with is Fedora based. Apache runs as apache:apache. To allow for e.g. php to write to a file the file needs to be chmod 777. 755 is not sufficiant.What I'm wondering is basically how set up permissions like they should be on e.g. a "shared web host".My main problem is that if I set a permission so that one user cannot access anothers home folder, then apache can't read from the public_html folder either.

To keep the users out I need to set chmod 700. But to let apache to read I need to have at least execute on world,so a 701 basically works, but won't let some users in.So I'm really stuck on what to do. Have been concidering adding the apache user to the frous grours
below to avoid having to add the world execute flag, but is that a bad thing? Should it be the other way around, the users in the groups below should also be in the apache group?I was aiming at having 4 groups:

1. webapp: same as dev_int, but is the only one that can go inside the webapp/live folder to e.g. do an update from the repo.

2. dev_int: can read,write and execute everything in the "web root", including the two below, but nothing outside of the web root

3. dev_ext: can read write and execute in all client folders, but cannot access anything outside of the webapp root

4. clientsBasic ftp accounts. Has a home folder with a public_html, but cannot access any other home folders

Ubuntu :: Advanced - IT Groups Can Read / Write Files But Others Have No Permissions

Jan 28, 2011

I have a file server running 10.04. I have a user that belongs to 2 groups (users is the primary and IT is the secondary). I have permissions set up so that this user and other users that belong to the IT groups can read/write files and others have no permissions whatsoever. I have also set the umask to 0007 so that any files created have the effective permissions. My concern is this: since my primary group is users, is it possible for me to create files with the owner group IT for only this specific folder?

General :: Samba File Permissions For Multiple Groups In The Same General Path?

Nov 4, 2009

I'm using my Linux (SLES 10) server as a File Server at this point. I need to set File Permissions to nested folders differently to different groups. For example:

homesharedengineering* should be read only for groupA
homesharedengineeringadmin should be read & write for groupB Plus read only for groupA
homesharedengineeringautocad should be read & write for groupC Plus read only for groupA

I've been using Webmin and Putty to set permissions but Putty only allows me the Default Group, it won't allow me to set several groups on the same directory. Webmin seems to allow me to add multiple groups (Webmin --> Others --> File Manager --> Info & ACL tab will provide extended abilities) but when I add multiple groups, they don't seem to take effect? I'm wondering if my setup at the 'Share' level or at the hierarchy of my folder structure (unix based) needs to be set specifically?

Ubuntu Servers :: Get A List Of Both The Local Groups And The Groups In The Active Directory?

Feb 4, 2011

I already know of a work around to fix this problem, but I guess my question is why is this not working as expected? I am using a Windows Server 2008 R2 Active Directory for authentication.

I have run auth-client-config for the ldap profile and pam-auth-update. When running getent passwd, I get a list of both the local users and the users in the active directory (with populated information in the Unix schema extension). When running getent group I get a list of both the local groups and the groups in the active directory (with populated information in the Unix schema extension).

Interestingly enough, though, when I run su DOMAINUSER, after the prompt for the password I get an authentication error. In /var/log/auth.log I can see an entry with pam_ldap: missing "host" in file "/etc/ldap.conf". The SRV records in the DNS servers resolve correctly. I've checked this with nslookup and I have seen the records within my zone file. Obviously if the ldap.conf file is working with getent and the ldap server is resolving from the SRV records, it is working fine.

The interesting part is that the Windows Server 2008 R2 AD machine shows in the event viewer that there was a successful authentication, yet the Ubuntu box says no. When I add the host within the ldap.conf file, everything works...getent and the actual authentication, either initial login or su.

Ubuntu Servers :: Mapping UNIX Groups To Windows Groups?

Oct 12, 2010

I am currently trying to set up a Samba domain server. In the Samba-HOWTO-Collection I found an
example file.(Point 3.3.3.1) In the explanations of the example below, the author says I need to map UNIX Groups to NT Groups. He writes a shell-script of how one could do it, but when I copy it and then execute it, I get the error:

Bad option: rid=512
Bad option: rid=513
Bad option: rid=514

The other groups do get mapped, just the Domain Admins, Domain Users and Domain Guests dont. This is the shell from the HOWTO:

#!/bin/bash
#### Shell-Skript f ̈r sp ̈tere Verwendung aufbewahren
net groupmap modify ntgroup="Domain Admins" unixgroup=ntadmins rid=512
net groupmap modify ntgroup="Domain Users" unixgroup=users rid=513

General :: LFS /tools/bin/groups Not Displaying Supplementary Groups?

Jun 8, 2010

So i am at the stage of about to install the basic system and am using a derivation of the package management provided by Matthias S. Benkmann. To this end I am using his useradd and groupadd scripts to update the files:

/etc/passwd
/etc/group

My issue is that when I run the commands(created as part of temporary system when installing coreutils):

Code:

/tools/bin/su linux
#then as user
/tools/bin/groups

(here linux is the name of the user) This only returns the user being in the group named after user but not the additional group of 'install' Also, prior to logging in as user, if I use this command as root:

Code:

/tools/bin/groups linux

linux install This then returns that the user is in the correct groups. Lines from relevant files look like:

Code:

#/etc/passwd
linux:x:10000:10000::/usr/src/build:/bin/bash
#/etc/group

Server :: LVM Planning - Disadvantage To More Volume Groups?

Apr 28, 2009

I've been using LVMs on some of my Linux servers for years without fully "getting" them. Doing a lot of things by rote. As I setup a new RAID though, I realize I don't have to be so rigid. I inherited a mission critical server with five independent disks

Code:
/dev/sdb1 /usr1
/dev/sdc1 /usr2
/dev/sdd1 /usr3
/dev/sde1 /usr4
/dev/sdf1 /usr5

I've bought an external RAID5 box that I plan to migrate the data to and was planning on this layout.

Code:
Method 1
VGLogVol
/dev/sdb1/usr1 -> usr1disk1
/dev/sdc1/usr2 ->usr2disk1
/dev/sdd1/usr3 ->usr3disk1
/dev/sde1/usr4 ->usr4disk1
/dev/sdf1/usr5 ->usr5disk1

Mainly because the 1 to 1 correspondence is easy for me to understand, and what I'm used to. But I realize it doesn't have to be that way, and I could have one VG with all the LVMs as parts of it, i.e.

Code:
Method 2
VGLogVol
/dev/sdb1/usr1 -> arrayusr1
/dev/sdc1/usr2 ->arrayusr2
/dev/sdd1/usr3 ->arrayusr3
/dev/sde1/usr4 ->arrayusr4
/dev/sdf1/usr5 ->arrayusr5

Is there any advantage to one way over the other? Would using one VG with multiple LVs be kind of like "putting all my eggs in one basket"? Do more VGs and LVs introduce unwanted overhead into the LV Mgr that should be frowned upon? If both methods are equal, I go with the method1. Just more clear to me. But now that I understand the second, I could go that way, if there's a compelling reason.

Server :: Differentiating Volume Groups - New RAID

Jul 1, 2009

I'm experimenting on a new 5.7TB raid we got for one of our servers before it goes into production. I'm carving the space up into Volume Groups and Logical Volumes. Below is some sample output:

[root@server newhome]# vgdisplay
--- Volume group ---
VG Name extraid_sdd1
System ID
Format lvm2
Metadata Areas 1
Metadata Sequence No 2
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 1
Open LV 1
Max PV 0
Cur PV 1
Act PV 1
VG Size 1.82 TB
PE Size 4.00 MB
Total PE 476804
Alloc PE / Size 476804 / 1.82 TB
Free PE / Size 0 / 0
VG UUID LJPJVE-fekS-crS8-uugk-l13z-0NG0-FWv3M3

--- Volume group --
VG Name extraid_sdb1
System ID
Format lvm2
Metadata Areas 2
Metadata Sequence No 4
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 1
Open LV 1
Max PV 0
Cur PV 2
Act PV 2
VG Size 3.64 TB
PE Size 4.00 MB
Total PE 953608
Alloc PE / Size 953608 / 3.64 TB
Free PE / Size 0 / 0
VG UUID kzlLN4-PyrX-LYUS-h1Tc-1S9F-jVV0-XU5tcK

Because I created this, I know that the second 3.64tb Volume Group, extraid_sdb1, is composed of two physical volumes, /dev/sdb1 and /dev/sdc1, each one 1.82TB in size. My question is, if I hadn't made this and had to work backward, how could I discover that info? I can see that the second VG is composed of 2 PVs by the "Cur PV" line. But if I didn't know that they are my /dev/sdb1 and /dev/sdc1, how could I break that out, as well as their sizes? If it matters, this system is running FC6.

I have configured a file server with samba and winbind in RHEL5.I am able to allot permission for the active directory groups to my Linux folder.No issues.But i want to set multiple groups of active directory to get ownership to a single directory. Say there are 3 groups a,b,c to have permissions to a folder of the Linux machine.

Code:

chown -R root:Active_directory_group_name path_to_linux directory

I have set

Code:

chmod 770 /myshare

meaning that user and group would have full rights to /myshare

Code:

chown root:a

works great I tried with the option of

Code:

chown -R --reference=/etc/shares_own.txt /myshare

In reference file(shares_own.txt) i gave the entry as

Code:

root:a,b,c

Server :: Samba Shares And The Notion Of Group Of Groups

Feb 9, 2011

this is really a brainstorming thread seeking advise on how to setup some samba shares within a small office network. For the quick judgers:

-no I'm not an IT expect and I'm not even the IT at the office, I just fill in this gap too.
-I have looked into several samba 'by example' tutorials - none seems to fit my needs or answer some of my Qs.

So I seek advise from your experience: What do I know:

-the functionality of the setgid to have subfolders inherit the group owner of the parent folder
-the fact that I don't want samba in 'share' level in order to register the owners of files
-the functionality of acls that enables inheritance of rwx permissions to subfoldrs of a parent folder.
- the groupmod -o option but that doesn't help apparently.

So this is a 25ppl civil engineer consulting office. The physical groups of ppl working here are: engineers, drafters (those who generate the drawings , i'm not sure if thats the correct term), and secretaries. The job usually is done in the following way, once a project commences a project folder gets generated and everything is done in there. incoming mail arrives there (secretaries put it there), engineers do they calculations on speadsheets, write reports and do draft drawings and, finally, drafters take the draft drawings and finalize them. So pretty much everyone of these 3 groups needs write access to the main project folder.

How do I accomplish that? as which group should I create the project folders? It came to mind the notion of group of groups. Now that the actual owner of the file is not so important anymore (several engineers will need to have write access to the folder) and group becomes important, it would be nice to have the ability to add... groups (instead of users) to groups! so that the permissions to a group are inherited by its children groups... Does such functionality exist of can it be implemented somehow?

How do I go about giving access to everyone and at the same time, NOT giving up on the 'user' secutiry level of samba (and NOT just giving rwx permission to 'others'? Is it possible? or Should I instead forget about individuals and match the 'physical groups' to 'linux users' and 'groups of groups' to 'linux groups'? ( This means I should give on ownership of files by individuals )? Since its a small office some work is mixed - engineers might pickup incoming email, a secretary might do abit of drafting work etcetc.
