Disabling TLS 1.1 in Centos 7 cockpit
Sure did!
I am even playing with different options (including NONE) and it seems
to ignore the contents of ssl.conf
I have tried
Environment=G_TLS_GNUTLS_PRIORITY=NORMAL:+TLS1.2:!TLS1.1:!TLS1.0:!ECDHE-RSA-AES256-SHA:
Environment=G_TLS_GNUTLS_PRIORITY=NORMAL:+TLS1.2:!TLS1.1:!TLS1.0:!ECDHE-RSA-AES256-SHA

sorry corrections:
For this test I created a 40GB lvm volume group with /dev/sdb and /dev/sdc
then a 40GB LV
then a 60GB VDO vol (for testing purposes)
vdostats --verbose /dev/mapper/vdoas | grep -B6 'saving percent'

Slow terminal response Centos 7.7 1908
Hey!
I have a strange condition in one of the servers that I don't where to
start looking.
I login to the server via SSH (cant doit any other way) and anything that I
type is slow
HTTP sessions timeout waiting for screen redraw. So, the server is acting
"slow".
server is bare metal. no virtual services.
no alarms in the disk raid
note: server was restarted because of power failure.

NFS Server on Centos 7.6.1810 dying without reason
I managed to get NFS statistics just before server rebooted.
I can reproduce this every time.
Question: Am I saturating the SATA bus on the NFS server so violently
with the SSDs that the server hard reboots?
Perhaps due to the RAID 6 nature of operations?
Server info
AMD EPYC 7281 16CORE
32 GIG RAM
6xSATA3 SSD 1.9TB in mdadm RAID6

Jitsi Meet on CentOS 7 ?
Benson, no SELINUX was not enabled. The instance was selected without it

Netapp like snapshots using Centos 5/6 direct attached storage
Hello,
I'm researching the best method of providing about 20 users in a production environment the same functionality as they would have on a Netapp NFS share.
The O/S I will be using is CentOS 5 or 6 (max flex on which one) and the hardware is a disk array directly (12 SAS disks 7TB un-configured brand new) attached to a HP 580 G 7.
I've done some reading on ZFS on Linux ,fuse-ZFS,

Disabling TLS 1.1 in Centos 7 cockpit
Oops, excuse my typo
Create /etc/systemd/system/cockpit.service.d/ssl.conf containing
[Service]
Environment=G_TLS_GNUTLS_PRIORITY=NORMAL:-VERS-SSL3.0:-VERS-TLS1.0:-VERS-TLS1.1
Then
systemctl daemon-reload
systemctl restart cockpit
To verify that TLS 1.1 is disabled,
echo test | openssl s_client -connect localhost:9090 -tls1_1 2>&1 | grep -e Protocol -e Cipher
The expected result is:

What's your dd command? Are you sure you are writing to the raw disk
and not inside a partition?

guidance on enabling 2FA at Linux GUI level
Hi all,
running a machine with Centos 7.6 that already has a 2FA PAM- enabled
module for SSH logins.
Is there a document that talks about configuring Centos 7.6 default GUI
(Gnome) to use 2fa with PAM?
thanks,

LUKS layer / best practice
Also, if you want to use deduplication (via VDO) then you must
remember to "dedupe then encrypt"

Jitsi Meet on CentOS 7 ?
Hi Centos friends.
I had some time to write a spartan tutorial on running the latest stable
Jitsi Video Bridge and Jitsi Meet and Centos 7.7.
I wrote it while testing it so this WORKS and I am currently using it for
fun with the kids.
I do have the server currently running but blocked by my firewall. I am
willing to allow a few of the people such a Kovacs and others to connect to
my Jitsi server
