View 1 RepliesI have a problem with my external hdd, I mounted it manually and in the mount table it says ive got rw permissions. But when i try to change permissions it says:
chmod: changing permissions of `whatever': read-only filesystem.
This is my mount table:

Question: How do I set up my 2nd HD with correct permissions? Background: I had previously a dual boot XP+10.04 with a 2nd HD formatted as NTFS. With this I was able to use my rsync and backintime to my 2nd HD with no issue. My new set up is EXT4 on both HD.
(I even tried to reformat my 2nd HD as NTFS, but that didnt fix the issue) I followed [URL] to mount the 2nd HD and get permissions. But now when I run backintime i get this error: [E] Error: rsync: opendir "/home/myhome/.ssh" failed: Permission denied (13) I did my requisite reading for a newbie, and am stuck. I ran backintime as root, and it backed up ok. How do I run my user version of backintime? (i.e. How do I fix the permission issue?)

View 6 Replies View RelatedI 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...
I have an NFS server on Windose Server 2003. I use it to back my Linux/Solaris databases up to. I mounted the NFS share on the Linux box. I was testing the permissions to it, and accidentally did a chown sybase:sybase /OLBackupOLBackup is the root directory of the NFS share. When I did the chown command, it changed the permissions on the share. Now it seems that linux is controlling the permissions. In windose I cant add users/groups. How can I remove Linux from owning the permissions. Im not sure if this is a windose issue or a linux issue, but figured I would start asking here first.
View 1 Replies View RelatedI'm planning a NFS share for a small enterprise (25 NFS clients). I need to create a directory structure but I'll need to set up differents permissions (rw/ro) to some directories of the tree. I wonder if it's possible to grant access using groups IDs, so that would be ideal for this application. Is it possible? I was thinking that I would kneed some kind of centralized user info, such as NIS or LDAP. Is that necessary?
View 4 Replies View RelatedI am having a bit of an issue with a NFS configuration. Initially I had no issues when both the server and client were both running Ubuntu Karmic. The client is now running Fedora Core 12 and when I mount the share I get "You do not have the permissions necessary to view the contents of Mnt". I came across this troubleshooting guide and it suggests that the issue may be the UIDs are not in sync on the server and client. If this is the issue, which usernames do I need to sync and how would I do that?

View 3 Replies View RelatedI have just started using linux. I have setup an ubuntu apache2 server. It has been running brilliantly and I am highly impressed with the Linux system. My box is an HTTP server and I am hosting a website on it. I have VSFTPD installed and functioning as my FTP software. It has worked fine so far but I have been a bit annoyed that I have had to set permissions for each file I have put on there.
Now I have run into a serious issue with the permissions being set to 600 and I really need them to 755 because I am running an automatic upload for a webcam and the Image can't be accessed due to the automatic permissions of 600 being set to the image. My extensive windows background tells me that I need to apply the correct permissions to the WWW folder and get the files to inherit these permissions automatically.
I am running into a Brick wall with this. And thought that the knowledge and expertise here would be a good place to seek help.I have CentOS 5.4 server running Samba on a WinBloZ network. I have the groups all setup and that aspect works fine. But here lies the issues.In a shared directory with group permissions set if someone on the group with permission to this directory creates a file they are the only person that can edit / modify that file. That file need to be editable by the entire group. But the only way thus far I can achieve this is to manually chmod the files in the directory. I know there is a way to fix this, but I have not found it. Can someone please explain how to make this work for me.
View 1 Replies View RelatedI have a Samba share set up on a SUSE server that about 30 Windows XP clients are connecting to on a daily basis. They connect using Winbind and their Active Directory usernames and passwords which are stored on a Windows small business server (Server 2003). The share is called "company" and it's right off the root of the partition. Within "company" there are about 75-100 folders, most of which need to be publicly available and publicly writeable. There are a few that need to be locked down to a certain group of people so I've used group membership and access control lists for those.
The permissions on new files/folders still aren't right though, so I'll just try to explain what I WANT rather than trying to resolve what is HAPPENING since I think that'll be easier. Currently the entire company directory and all subdirectories and files are user-owned by "administrator" (an active directory domain admin). I'd like new folders and files created anywhere in that directory or any subdirectory to maintain that ownership by administrator, regardless of who creates them.
Likewise, the entire directory and all subdirectories/files are group-owned by "domain users" (a builtin active directory group which is pulled in via winbind) which gives everyone write access to everything. I'd like that ownership to be maintained as well on any new files or folders created in /company or any subdirectory therein. I think this is working for the most part as I've set the setgid bit on company. I'd like any files or folders created in /company or any subdirectory therein to have 770 permissions (rwxrwx---).
So, what I want is regardless of who creates a file or folder anywhere in "company" - it should be owned by user "administrator" and group "domain users" and have 770 permissions. I'd like to make a little tweak to this post. Above I said I wanted anything created under Company to be created with group owner "domain users" - that actually only goes for anything that will be public. On the folders I have locked down via group membership and ACLs the new files/folders created within should maintain ownership of whatever group owns that directory. I should be able to do this by setting rwxrws--- permissions on secured directories.
I have a home network setup. The server has OpenSuse 11.1 installed. I have a laptop with Ubuntu 9.04 and my wife has an iMac. My wife an I are both members of the same group and that group has full rwx permissions in the directories we access. All the directories we need belong to that group. We can all connect to the server and access files without a problem. However it seems that all the files are read only for the other user. In other words if I make a directory on the server and save a file in there, I can access it with full permissions and my wife only gets read access and vice versa. What should I be looking out for or checking that would enable both of us to have full permissions other than setting permissions on the directories to the group we share (which I have done)? I also have one other question.... I notice that some users and some of the groups have the same number. I assume that this is normal?
View 1 Replies View RelatedI'm setting up an automatic mount point on one of my servers. However, for this file I only want certain people (permissions) to access it once it is mounted. I'm figuring I need to place this either on an ACL (via setfacl) or by configuring this in my mount point config file (auto.misc) . Has anyone done this before, restrict use of an auto mounted directory?

Trying to setup a file server for a small group of users and I am in need of help with file permissions with Ubuntu Server 10.10.
I have a single share mapping (ex /media/hdd1/share1). There are several folders that everyone will need read/write/edit permissions and there will be a few folders that all users will need read permissions and a couple of users will need read/write/edit permissions.
I have tried several things and as long as I create the folders/files through ssh using sudo, the permissions are fine, but when the users create file and folders through their computers (mixture of Windows and Mac) that user becomes the owner and no one else can write or edit those files.
I am using SAMBA and though it was a config issue with that but I logged each user directly into the server with the same issue.
I tried sudo chmod 777 /media/hdd1/share1 but all newly created files have the above issue.
I have a server running RHEL6 and a virtual machine also running RHEL6. I created a directory /home/data on the server and another on the VM.

View 4 Replies View RelatedI'm having an issue that I've seen before on other OS's (Solaris), but I'm coming up blank on solving for an NFS mount shared from RedHat I've googled this, and looked through all the FAQs and mail lists I can find.
The issue is this:
Whenever a new file is created from an NFS client to an NFS mounted file system, the group and world permissions are being stripped such that any new file created ends up with 0600 as the file permissions. On the server, I have tried various sharing options (all_squash, anonuid, anongid, no_acl) with no luck. I've looked at the underlying mount point ownership and permissions, checked the file system acl's (getfacl...they match the visible file system), and set the custom SELinux (not mine) config to permissive. The file system is on an LVM partition, and has an SELinux group assigned in /etc/fstab. I've unmounted it, and performed a vanilla mount (no options). No amount of trial and error is working. Any file created by any user on an nfs client machine creates files with 0600 permissions, and local users on the nfs server create files with permissions based off their umask settings. I originally thought it was due to mismatches in permissions from Windows to Linux (The server also NFS shares to Windows 2K boxes using hclnfsd (PC/NFS)), but I confirmed the same issue between RedHat systems.
One thing I'm wondering from my reading. It's mentioned in many places that ownership should be root in most cases and not some other user. This entire file structure is owned by a user that is ONLY local to the server box (long story, but the box is isolated....no DNS and only local users and settings).
On our fileserver, we primary use samba to share files to our users, but a few users have to use ssh/sftp to access the file server. In samba we have the shares setup so that permissions are forced to be the correct group owner and group read/write. The problem is those few who access via ssh/sftp. There files do not have the correct permissions. These people are not the most computer savvy, I'm dealing with biologist here. Is there some way to fix this or will I just have to setup a cron job to go through and set permissions periodically?
