similar to: Limit user password by time

chage apparently depends on the shadow file which is day-based. You might want to be more specific when you say "limit", are you trying to force password changes every 2 hours or force logout every 2 hours or something else? The reason I ask is you're probably into the "create your own method" arena where exactly what you're trying to do may greatly influence the

Once upon a time, Leroy Tennison <leroy at datavoiceint.com> said: > The executable could be placed on mounted read-only media That's not as secure as you think. 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. Il 01/07/20 16:04, Leroy Tennison ha scritto: > I've used rsync (but probably not for the size you're referring to), it works and has enough features to meet most needs. I have had a single situation where corruption occurred during transfer (a few times, have no idea why),

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

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?

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

There was a thread about C7 bash completion back in August last year, but it doesn't have answers for this problem. Example: "yum install /path/to/local/package" works fine with tab completion to fill in the path and package bits. However, "yum --debuglevel="1" install ..." just gets stuck and doesn't offer anything. The only option is to type everything

Hi, how can DNS reliability, as experienced by clients on the LAN who are sending queries, be increased? Would I have to set up some sort of cluster consisting of several servers all providing DNS services which is reachable under a single IP address known to the clients? Just setting up several name servers and making them known to the clients for the clients to automatically switch isn't

We currently have a Brother MFC-5490CN. Printer firmware is dated June 1010. (yeah, 10 years old). Few years ago the brother software wouldn't work for printing under Fedora. No problem, can print under Windows 10. Then it stopped scanning. Could still print...under Windows. Now, to fix the scanning features working I installed updated drivers under Windows, now it scans like champ, but

> Yes, breaking changes. Doing this *will* cut off support for older browsers. On purpose. Old browsers aren't really the problem. Even ff 45 (?) from CentOS5 will happily access a TLSv1.2-only server. The problem is user that have old versions of software installed with no TLSv1.2 support. SVN, python 2.7 scripts, etc.

Hello, I would like to know if it is possible to configure a password that expires, once user has logged, after 2 hours, for example. Thanks.

This is unfortunate. https://wiki.libvirt.org/page/TroubleshootMacvtapHostFail To the "normal" user - BRIDGE means guest is on the same network and has access to the host. Bummer. Jerry

Let me start out by making clear I *LOATHE* gnome, ok? So I don't want to hear about it. What's happening is this: I did this: yum groupinstall "Development and Creative Workstation" yum groupinstall "KDE Plasma Workspaces" Now, when I go in graphical mode, I try to change to kde on login. Nope - minutes later, I can see a cursor, and a gray screen. Ditto on the

I've several USB <-> RS-232 dongles around. As well as a few embedded devices. They all "Just Work (tm)" on Redhat, CentOS, Fedora, Debian, Raspian and Kali. Knock on wood - never had a problem using any of them. As the drivers are part of the kernel, I'd expect any distro using a recent kernel to do well.

How do you know when a Linux system has been compromised?? Every day I watch our systems with all the typical tools, ps, top, who, I watch firewall / IPS logs, I have logwatch setup and mailing daily summaries to me and I dive deeper into logs if something looks suspicious. What am I missing or not looking at that you security gurus are looking at? I subscribe to the centos and SANS
