Networking :: Permission / Group After Sshing Into Box
Nov 4, 2010
I've got a problem with groups on linux (slackware). I'm trying to ssh from one computer into another to do some work, but I'm running into permission issues.
If I do the work locally as a user
If I do the work with ssh as root
If I do the work with ssh as a user ;(
Both computers are mine. (By locally, I mean physically sitting by that computer logging in the normal way.) When I log in locally as a regular user I'm a member of the following groups: 'users floppy audio video cdrom' But when I ssh into the same computer, being the same user, I'm only a member of the group: 'users'
Q1. What gives? Where/How can I change this?
Q2. Also, where do linux/slackware store the group information? According to /etc/group I'm only member of 'users'. Where does it keep the info that I belong to 'users floppy audio video cdrom'?

I've installed slax6 onto an ext3 partition and setup a users account, i've also just managed to mount some virtualbox shared folders which are working and i can access them fine. The problem is I cannot seem to give limited user accounts access to them. root can access them no problem! but right clicking and changing the permissions do nothing, because once I click apply, reopen the menu, the changes have reverted. I've tried chmod'ing them.. chmod o=rwx /mnt/folder I used 'o' because I can't seem to change the group permission for the folder. The shared folder I am mounting is formatted in NTFS and the other in ext3, I can't change the permissions of either.

Me and 2 others are working on a website (Bob, Mike, and Joe). We made a group called developers and each of us are in the developers group. The Apache server runs as www-data. When we upload files, the file owner is the users name and the group is "developers".
/etc/group has the following
Code:
www-data:x:33:
bob:x:1000:
mike:x:1001:
[Code]....
I have always just set everything to 775 and just called it good. Well I don't want to wake up to a Russian political message plastered all over the site. It's time I do things properly.

I'm using ubuntu 11.04, I'm having some problem of ownership while sharing folder/files. to share i change the folder share option:1. Share this folder, then followed by 2.allow others to create and delete files in this folder3. guest access.Now if someone in my local network edit any file and save it, it gets locked. if some one copy their file in this folder the permission is marked as "no group" "no owner". and they get unaccessible to me. i tried doing chown <user> <folder> but it says Operation not permitted. Now how i can possibly share my folder on local network so that they can be edited by others without getting locked down , if they copy files i can able to modify them.

I'm having an odd problem (although I'm probably missing something obvious to a non-semi-newbie):I have a directory used for samba shares which is owned by user fred, a system user which the windows clients on my network authenticate with to access the shares. I, roger, want to access the directories without having to put my 'sudo boots' on every time, so I made the directory group users and added roger to that group, and changed the file/folder modes from 0755 to 0775.However I still do not have write permissions inside the directory; I still seem to be considered 'other' and hence only have read and execute.

Well, this is a problem that keeps on coming, and I never found a solution: Maybe it is just me misunderstanding how it should work, but:
1) do you confirm that, as a member of the group "fuse", I should be able to read the file?
2) of course, I could change the permission of the file, or read it as sudo, but sometimes this is not possible. how to achieve it then?

I'm trying to do something like thisi created a group called www and made this group the owner of the directory/var/www/htmlso i can read and write to it.of course I've add my self to this group, but it seems i can't read and write.the syntax i used was something like chown :www /var/www/html.didn't workonly when i used chown samurai:www /var/www/html i could finally could create new file.the reason i don't want to specify the user name is because I'm thinking of a scenario when i need to give permission to a large group of ppl and don't want to do it user by user.

Here are some example files that are shared through samba:
-rwxrwx--- user1 group1 file1.txt
-rwxrwx--- user1 group1 file2.txt
When user2 (who is also a member of group1) edits file2.txt the permissions change:
-rwxrwx--- user1 group1 file1.txt
-rwxrw---- user2 group1 file2.txt
user1 then has issues opening the file. This also goes for new files that are created (they are missing the group execute permission).
I have set the option "create mask = 0770" in my smb.conf. Without this set, permissions default to something like -rwxr--r--

I'm running Ubuntu 11.04 (guest) on Windows 7 (host) with the guest additions installed. I have an auto-mount folder that maps to my D: drive on the host which I can access using sudo ls /media/sf_D_DRIVE - however, even when my user (ross) is a member of the vboxsf group I get a permission denied error when attempting to explore it. I have restarted since adding my user to the vboxsf group.
This should work because I am a member of the group (which has rwx rights), so why doesn't it?
ross@panther:~$ ls -l /media
total 8
drwxrwx--- 1 root vboxsf 8192 2011-07-03 22:24 sf_D_DRIVE
ross@panther:~$ ls -l /media/sf_D_DRIVE/
ls: cannot open directory /media/sf_D_DRIVE/: Permission denied

I am experiencing a weird situation. When I ssh to, let us call it, box1 with a public IP, I end up sshing to box2 with a private IP. Both boxes can see each other since they have private IPs in the same network in the eth1 interface.
I don't know if this is good information to get anyone of you started with any feedback. If you need any other info that I am missing at the moment
Both boxes are running Centos 5.5

How can I create a user group that restricts Internet privileges to only members in the group, then I will assigns certain applications to join the group for access to the Internet.
For example, I want only group net to have access to the Internet. Group net is then connected to:
Code:
So far, I am using the gnome group policy manager that is standard with ubuntu but Its not working. It is possible that im misdirected and that I should use a firewall instead?

I've been tasked with fixing a Red Hat system that dies with a kernel panic during the boot stage:
Code:
EXT3-fserror (dev sda1): ext3_check_descriptors: Inode bitmap for group 4 not in group (block 67239937)!
EXT3-fs: group descriptors corrupted!
mount: error mounting /dev/root on /sysroot as ext3: Invalid argument
I can boot into a Rescue CD, but I'm a bit out of my element because I don't use EXT3 myself, and I've never had to repair a corrupted file system before.

I have a group (GROUP) with a number of users. I recently added a new user (NEW). NEW is able to read but not write group files, whereas all the other users in the group can read and write to the group files. The permissions for the group files indicate that all members of group should have write permission -rwxrwxr-x
/etc/group indicates that NEW is a member of GROUP
...
GROUP:x:501:GROUP,OLD,OLD2,OLD3,OLD4,....,NEW
[code]....
Don't know if it matters, but both OLD and NEW write to the GROUP files over an internet connection. why NEW can't write to GROUP files? Is there a maximum number of members in a group that I might have exceeded?

I have a number of users, categorised into various groups. I would like one of those groups ("developers") to be in the wheel group as well. I don't want to just copy the people from the developers group into wheel, because then when that group changes I'll have to change it in two places. Is there a way to specify that anyone in developers is in wheel, and have that be dynamic?

The server is named alpha and is running Archlinux. It is exporting a directory named /files. The server is a couple of years old and I have accessed it extensively from clients running Arch, Suse, PCLinuxOS, and maybe some others, all with no problems. The clients (3 of them) are new installations of Linux Mint 10 (Julia). When I mount the nfs all of the nfs files are visible as expected. However, the owner/group is drastically different than on the server.
I might add that I have set up user id's and group id's the same. My user is 1003 on all systems, and the users group is 100 on all systems. When I am on alpha (via ssh), here is a partial file listing.
Code:
[dick@alpha dick]$ ls -l
total 9740
drwxr-xr-x 3 dick users 4096 May 16 2009 airplane
-rw-rw-r-- 1 dick users 240978 Jun 27 2009 Alice Grad 1934.pdf
-rwxr-xr-x 1 dick users 444 Jul 8 2007 alpha2ast
-rw-r--r-- 1 dick users 444 Sep 2 2009 alpha2charlie
[Code]...
If have searched the Mint forums, LQ forums, and google in general. I must be missing something in my search because I can't believe that no one else has this same problem and I am having it on 3 different boxes.

A bit of an oddity that I've recently run into with my storage folder in my system; it's a newly installed drive that I've set to mount at /storage. When I first tried to use it, programs that I used that attempted to write to it tossed Access Denied errors at me in their own way. Checking the permissions (at the Terminal, ls -l / | grep storage) showed that /storage was set to 'rwxrwxr--'--Owner and Group were given full read/write/execute, but Others could only read. However, my logon to my system is a member of group root. Why, then, with the above bits set, would I not be able to write to it? Changing Others permissions to rwx (and presumably rw would have worked out for me since I don't leave anything executable there) allowed me to write to it, but I don't understand why that would have been necessary. So far as I'm aware, the prior drive that was in my system--mounted at the same location--did not need this treatment.

Is it possible to allow a group/user to execute a command, where one of the parameters of the command is a group as well? example that does not work as intended:
Code:
Cmnd_alias SU=/bin/su -l %group1 This example works sortof, it treats the "%group1" literally. I know I can list out the "/bin/su -l <eachuser>", but as you can imagine that is impractical. In this example, I want people in group2(not shown for brevity sake) to be able to su to someone in group1
