General :: File's Group Changing When Replaced Via Scp
Oct 26, 2010
on my Fedora test server, there is a webdev group for all developers and the files under /var/www are owned by apache:webdev. Each developer is set up per normal, with each getting his/her own entry in /etc/group, then I add them to the webdev group (all from the command line). Things seemed OK, but when I edited a file as me the other day and updated it via scp, the ownership and group changed to that of my user, preventing a second dev from updating it later. How can I make sure that the file remains editable by all in the webdev group regardless of who updates it? Since it's a test server, the permissions are fairly loose at 775.

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?

Does anyone know how to change the primary group on a user without changing the password? I've tried updating the /etc/passwd and running usermod -g group userBoth of those does change the group but somehow it messes up the password so the user cannot get in with the same password.

just trying to learn linux here and have some comfusing moments.it is my understanding that if you own directories and files you maychange the group, ownership, and permissions on all of these as you desire.however, in my case I cannot make any changes in my setup on group, ownershipor permissions on any of my files or directories.get error message <operation not permitted>. I know as root you ar supposed tobe able to do anything you desire, however in my case I can go in as root andtry the same commands with the same results. it is as if I am locked out ofsystem as far as any changes are concerned.on my jump drive I have:
total 83832
drwxr-xr-x 26 jevans root 16384 1969-12-31 19:00 .
drwxrwxr-x 9 jevans jevans 4096 2010-01-15 12:51 ..

I turned my laptop in for repairs. I used someone else's USB drive to hold my pictures etc from that computer. I may have replaced the "pictures" folder tat was already on there, but I'm not sure if it was there in the first place. (Doesn't remember the "Are you sure you want to replace..." warning <.< >.>) I enabled hidden files, and there was a folder called .Trashes, instead of what you'd normally get. I copied my pictures onto my desktop, and then cleared the ones on the USB drive (left the folder). There was a folder named .000Trash-, or whatever it usually is. Only my pictures are in there. I'm confused, and don't tell me the pictures that were originally on the USB are gone forever.There's a tool for Windows, called Glary's Uilities that can get them back, supposedly. Not running windows, though

I have a CentOS 5.4 storage server with LVM/RAID1 setup, I need to change the motherboard from Gigabyte GA-G31M-ES2C to Asus P5K-E. After the switch, I got kernel panic during boot (the following is copied manually from the screen, is these stuff recorded somewhere in the log? I checked /var/log/messeges but didn't find anything):
Code:
Scanning and configuring dmraid support
md: Autodetecting RAID arrays
md: autorun....
md: ... autorun DONE
[code]....
I used CentOS CDROM and entered rescue mode to take a look, some findings:
1. Initially the drive label is different from my old system, for example the old sdb became sdc. I switched the SATA cable around to get this sorted out except one IDE drive (originally hda, now hde), but this drive is not used in RAID
2. After the label is fixed, I used mdadm to check RAID1 devices (md0/1/2/3), it seems each device is missing a drive (originally md0 is created by sda1+sdb1, now it's just sdb1, and thus degraded). I used mdadm to re-add the missing drive, mdadm --detail shows everything is fine now.
3. Step 2 didn't fix the error, so I "chroot /mnt/sysimage/" and took a look around, all the directories seem fine, include the ones on "main" volume group. vgscan/vgdisplay/lvdisplay shows all the vg and lv as they should be.

This is about ubuntu 10.04
I can import projects to my cvs repository only when the repository set to group owner cvs. Which is fine to me.
But I found the project folder/files that I imported into the repository have group name other than cvs (in fact, that's my username). And that prevents others to check out my code.

I'm studying Linux and just started reading about permissions and ownership. My question is how would you have multiple users or groups given access to a certain directory? When doing an ls -l I see the owner, group and others that have permissions that have access to the file or directory. But what if I need multiple different groups access to a particular file or directory all with different permissions?

I was doing a tutorial on scripting in bash. I saved my file on the desktop and I cannot seem to get to that file to execute it. Here is what I have been using:
I try cd Desktop says that there is no such directory.
I tried /home/me/Desktop same thing.

I Want to be able to let my girlfriend view my pictures folder while at the same time keeping my sister out. So I created a group "JessAndI" and made myself and her apart of that group. I changed the group of the directory recursively to "JessAndI" and gave the permissions to 770. She still isn't able to access or even view the directory unless i change the permissions to allow others whether it be 774 or 777. Am i doing something wrong? I've checked and double checked to make sure she is part of the group and the group is the group on the directory and all the sub-directories and files.

I'm on a regular Fedora 9 desktop computer with an ext3fs filesystem.
I'm trying to give myself access to /dev/ttyS0. This is because I'm developing code that uses a serial port. While I'm developing this code I don't want to be continually working as super user. I have the following information about /dev/ttyS0:
Code:
So as root I added myself (username freddy) to the group uucp. This is just temporary, for while I work on this code and try different stuff as user freddy. Once the code is established and I have a single program with a fixed name, I plan to give myself an entry in /etc/sudoers that will allow me to run the finished program.
Here's the info on user freddy:
Code:
The problem then is that now if I try to use /dev/ttyS0 I can't.
Code:
I thought that if I was a member of group uucp which is associated with /dev/ttyS0 that I would be given rw access to /dev/ttyS0. What am I missing here?
What the c stands for in the ls -l listing?

I have several directories, each owned by root and a group of the same name,By setting the sgid bit, I made sure that newly created files and directories are owned by the correct group, and that directories have the sgid bit set too.On each newly created directory or file, the permissions are set to 755. This is because this is the default umask, and I cannot change a users umask. I actually only want files created below a particular directory to have group write access, inheriting this behaviour to newly created directories properly.I'm not on samba or NFS, I have to do this for SSH users.The filesystem is ext3.I started to fool around with ACLs, but couldn't find what I was looking for.

I need to create a group that has the same permissions as the users group. Can I have the new group be a member of the "users" group to inherit its permissions?

I like to redirect the print output to a file for later analysis and I was able to do this in an old Fedora 9 but with the new installation of Fedora 13 or Ubuntu 10 it is not working! I always get an error when selecting a directory/filename like file:///tmp/output.prn.
How can I fix this problem?

I first installed linux as ubuntu version 9.04 straight off of a Computer Active CD and liked it so started to delve into file permissions and authorisations, simple stuff I suppose just so I could feel my way around things for a while. Using the built in Ubuntu software centre I downloaded and installed a prog which handles authorisations and I found that very helpful but then through the update manager I installed the latest distribution update (9.10) and now find that the authorisation software only lists a couple of things that I can get to and consequently every time I mount one of my hard disks I'm asked for my admin password even though I am logged in as administrator which is a hassle,
a small one but there all the same, as a newbie I realise it must be me not understanding something but I just dont know what, also in the previous version right clicking on the logging out panel gave you an option to remove the 60 second shutdown or restart delay and that has disappeared in the new version, again its really only just a nuisance thing but I find that sorting out this sort of thing will help me to understand the system

I created a folder structure as root and now need to transfer ownership to an ordinary user.
This question is linked to this one - [URL]
I have a folder /srv/app-share that needs to be visible/writeable to user1
I tried (as root):
root@server [/]# chown -R user1:user1 /srv/
But that did not work.

I have a problem with Fedora Red Hat (2.6.23.17), every time I restart the server, the eth configuration is deleted and replaced by a new one. For example, my configuration:
eth0 --> static ip address
I restart the server, then eth0 file is deleted and replaced by eth1 with default configuration. I try to create an eth0 and give it the static ip, I stop the network I get at the end: SIOCGIFFLAGS: No such device
But when I start it back I get: bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization. However, if I configured the static ip to eht1 it will work perfectly. But I still get "SIOCGIFFLAGS: No such device" when I stop it.

I was having a discussion with someone who asked me whether a Linux OS has to be rebooted when the hosts file is modified. From personal experience, on Windows I change the file but don't reboot and I've seen others do the same thing. I assume Linux has no exception(s), but is there any reason why a reboot is not required (to at least justify my actions)?

I have a really strange problem. I have a few files in a large directory that I want to make readable by everyone. So I try this:
sudo find readme* -not -perm -o+r -exec chmod +r {} ;
and get this:
sudo: unable to execute /usr/bin/find: Success
I don't know why it says Success, because the permissions were not changed. I verified by typing this:
find readme* -not -perm -o+r -exec ls -l {} ;
and get something like
-rw------- 1 root root 536871076 Nov 22 14:06 readme_20101122200429
-rw------- 1 root root 536871892 Nov 22 14:08 readme_20101122200642
-rw------- 1 root root 293458128 Nov 22 14:10 readme_20101122200859
as a last resort, I tried:
sudo chmod +r *
and got:
sudo: unable to execute /bin/chmod: Success
and again Success really means fail. So, I gave up and logged in as root and tried:
find readme* -not -perm -o+r -exec chmod +r {} ;
This time it worked. Why?
EDIT: /etc/sudoers looks like:
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
##Me
user1 ALL=(ALL) ALL

I have an Ubuntu development server and a Windows 7 workstation. I use Windows Gvim to edit files on the linux server, over a samba connection.Saving files from Windows change the Linux permissions in weird way depending on the Windows app I'm using and also depending on whether there's a file extension or not.Here are some testsNo extension; Notepad2: 644 to 764

-rw-r--r-- 1 matt matt 0 2011-05-28 07:09 testfile
