how to know when a system is compromised
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>

[OT] Bacula offsite replication
Hi Leroy, How I can confirm that during rsync transfer corruption are not encountered? Thank you in advance.

easy way to stop old ssl's
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

[OT] Bacula offsite replication
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-serial adapter for CentOS 7
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.

Limit user password by time
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.

Bash completion thrown by quoted option args?
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

HP vs. Brother Printers: Use with Centos/Fedora
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

CentOS 7 host with guests as bridge cannot access host
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

Upgraded to 7.10 from 6...
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

how to increase DNS reliability?
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

easy way to stop old ssl's
> 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.

KVM clone
Hello everybody. I have a simple question. If I clone an existing KVM image of win server with static IP, the clone will have the same IP? It's probably stupid question, but I want to be sure. I have a full updated centos 7 box. Thank you in advance. Nikos.

If you need it to have a different IP address/name/license then bring up a new definition without a NIC, login via virt-manager. For the IP address, search the registry for the current IP address and change the appropriate entries. Use standard Windows utilities to change the description/name. For the license,
