NFS with ACL ignore Umask

NFS share at client side user umask is 0022 and i want to change file and folder creation permission on share folder but without touching umask variable.

Solution:

After lots of digging i found umask is not working for NFS and NFS share so i found there is support of ACL on NFS share so i have used ACL for NFS file and folder permissions here i am not going to explain in detail but i show you my example and further you can read ACL manual for advance knowledge. I have set few permission on NFS share folder so anybody on client side create file permission will be according to ACL it will ignore UMASK Variable of Linux thats sound like great. here we go

/share <-NFS share folder where i am going to put ACL rules.

setfacl --set u::rwx,g::rwx,o::rwx /share

setfacl -d --set u::rwx,g::rwx,g:mygroup:rw,o::x- /share

Second option "-d" will set permission default for all folders and files which will newly create.

after putting permission you can verify it by "getfacl" command and "ls -l" command will mark files and directories with "+" sign.

I need your comment on this please give your input.

Good Luck!!!

What is bbPress

What is bbPress?

--------------------------------------------------------------------------------

bbPress is an internet forum package written in the PHP programming language and available under the GNU General Public License. bbPress is both open source and free software.

Origin:
The project was created by Matt Mullenweg to support users of WordPress. Existing bulletin-board software was overly sophisticated for those requirements, so bbPress was created with the same focus as WordPress: a functional and extensible core, with all other capabilities delivered through plugins.

Release History:
The first official release occurred on Oct 14th, 2006 and it was labeled as version 0.72 "bix", a revision number which was chosen (rather after than arrived at). Supported features included built in support for Akismet, integration with the WordPress user database, and RSS feed support. Early reviews described the release as "minimalist"
The announcement of bbPress 0.73 brought with it improved rewrite rules, a new template, support for languages other than English, and an easy-to-use installer similar to WordPress.
The latest official release 0.80 "Desmond"added more features, such as better timezone configuration and forum deletion.

Development:
The development of bbPress is formally managed through an issue tracking system. Informal discussion and support is available on the bbPress development forum

Features

Fast and light
Simple interface
Customizable templates
Highly extensible
Spam protection
RSS Feeds
Easy integration with your blog

Local YUM Repository

Sometimes, especially when you create your own RPMs, it is extremely useful to keep them in a local YUM repository. The advantage of this is that, when you install a package, YUM automatically resolves any dependencies, not only by downloading the necessary packages from the other repositories you might have in you list, but also by using your local repo as a resource for potential dependencies.

So, when installing a package (eg my_package.rpm) with YUM, you are supposed to have already created RPM packages for all of the my_package.rpm’s dependencies and to have updated the repository’s metadata, so that yum is able to resolve all the dependencies. If these dependencies do not exist in any of the repositories in your list, then, in short, you cannot install your package with yum.

How to create a local YUM repo

You will need an utility, named createrepo. Its RPM package exists in Fedora Extras. To install it, just run as root:

# yum install createrepo

Then put your all custom RPM packages into local directory (I am going to copy this RPMS on my apache web directory path). This command copy all RPMS on your CDROM to local system disk

#cp /mnt/cdrom/RedHat/RPMS/*.rpm /var/www/html/local_Redhat_repo

After copying run this command to create metadata for repo, This command will create new with name "repodata" inside /var/www/html/local_Redhat_repo

#createrepo /var/www/html/local_Redhat_repo

Now restart your apache webserver

#service httpd restart

Create new file in /etc/yum.repos.d/local.repo and add this line in that file

[local]
name=RedHat-$releasever - Base
baseurl=http://127.0.0.1/local_Redhat_repo
enabled=1
gpgcheck=0



Now to test this setup run this command

#yum install list
#yum grouplist
#yum install .rpm

Notes:- I am using HTTP server on my setup but you can use NFS, SMB, FTP or Local directory to access repo
