6 August 2018, 20:02 UTCGet ready for the SegmentSmack and FragmentSmack TCP vulnerabilities.

Follow along here: https://people.canonical.com/~ubuntu-security/cve/2018/CVE-2018-5390.html
More here: https://www.kb.cert.org/vuls/id/962459
Very brief bit from kb.cert.org -

Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue()
and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service.
An attacker can induce a denial of service condition by sending specially modified packets within
ongoing TCP sessions. Maintaining the denial of service condition requires continuous two-way
TCP sessions to a reachable open port. Thus, the attacks cannot be performed using spoofed IP addresses.

26 July 2018, 16:41 UTCBroken, but just wait! - High CPU usage issue in Azure AD Connect Health for Sync - update - 8/16/18
We will update this article when the new version of the Azure AD Connect is available. It is the middle of August, no article update, but updates for the AD Connect are available....
So, don't apply updates, and just wait... - at lest for the lesser AD Connect customers...
https://support.microsoft.com/en-us/help/4346822/high-cpu-issue-in-azure-active-directory-connect-health-for-sync
Short version for when they redact the best part of the article: (or make it a 404)


Symptoms
You experience slow performance and high CPU usage (reaches to 100%) issue in a machine that runs Azure Active Directory (Azure AD) Connect Health for Sync monitoring agent. In task manger, you notice that the process MIcrosoft.Online.Reporting.MonitoringAgent.Startup uses the high CPU usage.

The issue is not limited to specific Azure AD Connect Health versions and operating system versions. 

Cause
This issue occurs because June 2018 update of NET framework 4.7.2 is installed in the machine, and Azure AD Connect Health for Sync monitoring agent does not fully support this update.

The following .NET framework update would cause the high CPU issue of monitoring agent:

.Net framework update

OS version

KB4338420

Windows Server 2008

KB4338606

Windows Server 2008 R2

KB4054542

KB4054590

KB4338814

KB4338419

KB4338605

KB4345418

General

Resolution
For Connect Health for AD DS and AD FS:

To resolve this issue, install the Azure AD Connect Health Agent, version 3.1.7.0 that is released on July 2018.
It can be downloaded from Connect Health public documentation.

For Azure AD Connect:

A new version of the Azure AD Connect will be released soon. It will contain a fix for this high CPU usage issue.
We will update this article when the new version of the Azure AD Connect is available.

16 June 2018, 4:54 UTCTariffs, what can we make of them.

So, the whole basis is on the current US / China (U.S. against China - tariffs)
are based on a Nixon era visit and some follow up in 1974.

Interesting.

Digital VS Analog


In the digital world things come " now":
 and must be responded to "now"

in the analog world,
 things come "now" and must be responded to:
 when you can compose a cogent and salient thought.

5 June 2018, 15:50 UTCMore Backups... WindowsImageBackup to a share.

Forgot to write this down the first time, so here goes.
Steps I took to ensure writing to a Samba share worked:

Writing to an ext4 filesystem.

smb.conf share level config:
[sharename]
  browsable = no
  strict allocate = yes
  writable = yes
  create mask = 0700
  directory mask = 0700

I had a directory owned by just the user drwx------ windows-backup
within the share itself.

I am pretty sure the key is "strict allocate = yes" to get rid of the message:
The requested operation could not be completed due to a virtual disk system limitation.
Virtual hard disk files must be uncompressed and unencrypted and must not be sparse.
The operation ended before completion.
