similar to: Tools/mechanisms for the management of access permissions in big filebased datasets

Thank you. Basically our problem are not the ACLs or their support per se, but that we have to manage a huge number of individual ACLS (several hundred users in more than hundred projects) in multi-petabyte filesystem and still have to keep overview and control. Our problem is more the management side. Effectively we are looking for a tool that helps us manage these permissions and we

Well, there are extended ACLs if they're available in CentOS, when I first worked with them (long ago) they were new (and on a different Distro). I hope support for them has improved. They allow multiple users/groups to be assigned permissions to a file/directory. The problem then was that chmod (and other programs) were not extended-ACL-aware and could over-ride extended ACLs. There was a

Linux bind mounts can mount a file over another file (plus there's overlay filesystems), so it's possible to replace a binary even on a read-only device. -- Chris Adams <linux at cmadams.net>

Hi Leroy, How I can confirm that during rsync transfer corruption are not encountered? Thank you in advance.

There?s a real problem to solve, which is that the old user:group rwx Unix permission system doesn?t let you express common wishes like ?Angel & Bobby own this

I need to connect an older APS UPS unit to a machine running CentOS 7. Unfortunately the UPS only has a serial port whereas the computer does not. I am aware that there are USB-serial adapters but that the hardware or the drivers might fall short of expectations. Does anyone have positive experience with such an adapter? Or, conversely, would recommend avoid a particular adapter?

Without context it's impossible to make firm statements but, having gone through this a while back (and discovering that less than 1 percent of an examined list of connections couldn't support current ssl - mainly Apple hardware), who do you want to protect? Is it the minority who won't/can't upgrade or the majority who have? And, do you have to protect yourself from liability

Hi everyone, I have updated my backup server to CentOS 8.2. It runs bacula performing backup on disks. I would like to replicate backups on another offsite machine. I read about the ability to configure a new storage daemon in the offsite location and create a Migration/Copy Jobs. If I'm not wrong, it replicates only volumes but not replicate the catalog. I will try this. Another way to

USB to USB with standard USB cable will work. If one uses serial to USB adapter on the machine side (to create serial port through USB

Is it possible with "chage" to configure a password caducity for, at most, 2 hours? I think "chage" only allows caducity for, at least, one day.

Does such exist? I looked for dante and couldn't find that. I found and tried using a version from CentOS 6 but it didn't work. If anyone can point me to an rpm (or set of same) I would most certainly appreciate it. Thanks.

I have done some Googling on this but everything I've found appears to be at least 2 years old and mostly refers to Gnome TBH, I'm surprised nobody else has mentioned it - maybe it's only happened to me. At some point over the last few months the behaviour of the scroll bars changed and I'm finding it very annoying. Firstly, the arrows have vanished. Secondly, when clicking

You think this is irritating, what about when you're trying to replicate the network configuration to failover hardware... There is a way around this, I haven't tried it on CentOS but on Ubuntu there are kernel command line parameters: net.ifnames=1 biosdevname=0 which will override this behavior. Again, on Ubuntu these are added in /etc/default/grub as parameters to
