Suddenly my laptop kept disconnecting my wireless connection and turning to off airplane mode. Finally it got stuck in airplane mode off.
Resolution:
If the Airplane Mode is permanently off …. that means you would have accidentally pushed the on and off switch button on the side of your laptop. To enabled the mode on, just push the Wifi switch button back and forth to on position.
All the best of luck.
You’re suddenly receiving a “FATAL ERROR: Couldn’t agree a host key algorithm (available: rsa-sha2-512,rsa-sha2-256)” when trying to ssh into your Ubuntu Linx Server
Resolution:
The Couldn’t agree a key exchange algorithm is expected behavior with older versions of PuTTy or WinSCP.
To resolve this issue, upgrade PuTTy to the latest version via the below links. https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html . Try using PuTTy or WinSCP from a different computer/laptop if applicable.
All the best of luck. My problem was solved by actioning the above.

“The operation failed for an undetermined reason” transferring files through vSphere Client (2147256)
Initiating a file upload to datastore, and resulting in the operation failing with an error:
The operation failed for an undetermined reason. Typically this problem occurs due to certificates that the browser does not trust. If you are using self-signed or custom certificates, open the URL below in a new browser tab and accept the certificate, then retry the operation.
https://target-ip
Solution
To resolve this issue follow the solutions below as per the scenario.
Solution 1:
From a client system Web browser, go to the base URL of the vCenter Server system or the vCenter Server Virtual Appliance without appending port numbers or ‘vsphere-client’ extension.
For example:
https://vc.gs-01.esgnet.lan/ Enter your vCenter FQDN details on a Web browser
Click the Download trusted root CA certificates link at the bottom of the grey box on the right and download the file.
Go to
cmd – run regedit
In the Registry Editor window, navigate to…
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print
Then right-click in the blank space and choose ‘DWORD (32-bit) Value’ option under the ‘New’ sub-menu.
Rename the DWORD value to ‘RpcAuthnLevelPrivacyEnabled’
restart

Recently I was trying to update/upgrade Ubuntu 21.10 using the apt when I encountered the following error:
E: Could not get lock /var/lib/dpkg/lock – open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
A quick resolution that worked for me:
ps aux | grep -i apt
sudo kill -9 17796
ps aux | grep -i apt
rm -rf /var/lib/dpkg/lock-frontend
sudo dpkg –configure -a
It was working fine, and somehow, it just stopped working.
Solution:
Login to the backend of ExpressionEngine
Then go to Add-Ons – Modules –
../admin.php?S=0&D=cp&C=addons_modules
Click on Zoo Visitor
Then Go to installation » click the button at the bottom to Reinstall Everything.
Once the Zoo Visitor is installed, you do not need to change it, the installation makes sure everything is in place to just start. The default Guest member is necessary to accept registrations.

#Darktrace in action, does the job well! A great solution to supercharge your Cyber threat Landscape in light of the SolarWinds Orion attack.
Darktrace’s Immune System, applies AI to the cyber defense challenges for the first time, and has proven itself successful in detecting cyber-threats that existing, legacy systems cannot.
However, Darktrace alone is not enough in my opinion, you need to complement it with a good Modern NAC such as #ForeScout CounterACT. These two powerful security solutions cohabit in your environment you get pure good fire.
I know a lot of BIGGER enterprises like the Universities, Banks, Financial Services, Health Care Providers, Government Departments, Telecoms etc might already have Cisco technologies in-place; from the Switches, Wireless Controllers, Access Points and more so they might have Cisco Secure ISE which you could argue that it is a NAC and it does exactly the same, which enables a dynamic and automated approach to policy enforcement that simplifies the delivery of highly secure networks.
Very true, both Cisco ISE and ForecScout NAC possibly serve similar purposes, personally I would always pick ForeScout as my weapon of choice whenever I step into battleground against the cyber kingpins. With ForeScout you gain true visibility of all connected devices on your network within hours of deployment, and policy-based controls are often functional immediately.
NB: What I like most with these two solutions (Darktrace and ForeScout) deployed together under one roof, is that when Darktrace discover an rogue infected device I get notified instantly, and when I investigate the physical location of the misbehaving device down to a port on switch, ForeScout narrows it down for me nicely and clearly. Also keeping in mind that your policy-based controls could be configured such that it isolates or quarantines any rogue devices.
Should you need further engagement or require a POV (proof of value)/POC (proof of concept) team to rollout these technologies in your environment, kindly feel free to DM me.
#Fortinet FortiGate (100E) is the best firewall. The most valuable feature is the bundled subscription, which is IPS, antivirus and web filtering. It is easy to use and performs very well. This perimeter solution has powerful security features, and it’s a good product that integrates actionable threat intelligence and very well with a wide range of SIEMs.
NB: In my experience it is undeniable that technological solutions regardless of the vendor is as good as the skills and competence of the team that fully managed them.
Should you ever need a highly skilled (hands) team to handle all things Technology for your environment, kindly feel free to DM me.
