Securing Remote Access with SSH and Public Key Authentication
In this episode, our hosts explore SSH (Secure Shell), a protocol to establish secure connections between computers. We discuss the importance of SSH in modern networking, where secure remote access and file transfers are crucial. It dives into the fundamental concepts of public key cryptography, including RSA and ECDSA algorithms, and discusses their strengths and weaknesses. It explores how SSH leverages public key pairs for passwordless authentication, providing a more secure alternative to traditional password-based logins. It concludes by explaining how PAM (Pluggable Authentication Modules) can be used for identity access management and authorization, ensuring a more controlled and ...

Thank you for the kind words! I am glad you find it useful.
Well explained and useful video to everyone. Please do the same video using the Control tower using the 2 ISP interface.
Thanks for the feedback, appreciated! I will try!

Does this router by default use CAPWAP or mobility express?
Great question. ISR1131 provides a central LAN controller by Embedded Wireless Controller (EWC) feature so it kind of mobility express but you can use CAPWAP protocol to centrally manage APs.Watch the third part where we are setting up wireless - ruclips.net/video/OoOYCPRAACI/видео.htmlsi=K1t67Z1Bacill8MF

Hello, do you have a tutorial using Transit gateway instead of Virtual Private gateway in a Control Tower setup
Not yet but I will be posting TGW soon!
I’m trying to use with a BE-880Q, but the data never shows up. Only ***. When using the ucenter2 I can see all the NMEA messages there. I’ve tried many different baud rates, including the standard one that is 38400, but no success.
Thank for question, 38400 or 115200 is the baud rate I recommend, Please make sure you have Tx and Rx connected as per the program or simply try swapping them. NEMA is for serial communication and should not tied to any specialized software.
@@SDNTechForum Thank you. I discovered that the problem was with a library that I was using to read the GPS signal. When I read directly from the serial port, the problem was solved. However, regarding the baud rate of 38400, I tried to change it, but it didn’t work and gave me an error.
My problem now is with the compass calibration. Any idea in how to make it acceptable?
Thank you :)
You're welcome!

Hi bro thanks for this video, I was configuring for first time, and using iPhone after connect the vpn, I do not have any internet connection, but on pi, after connect the iPhone respond to the pings, but is all blocked to the internet
Hi, can you provide the pdf?
Can you create SSO HA pair after configs exist on Primary controller? Or, must build HA pair prior to applying any configs? Ie; let's say you start with a single controller, and later decide to purchase another for SSO?
what is the name of the battery and where can i get it
Please search "PISugar"
Hi @sdntechforum, I have a pair of c9800 in sso redundancy. I need to change the hostname. Do i have to break the sso to change the hostname of the secondary? Or a hostname command in the cli of the primary is enough as the hostname of the secondary doesnt seem to appear anywhere after redundancy is configured. And if i do break the sso will i be able to access the secondary wlc using the original mgmt ip. The hostname change is just to conform to the company standards..
Rezalet Unifi ve Asus da daha iyi arayüz ve özellik güven var.
thanks for this video it helped a lot
Thanks!
Welcome!
Hi, I would like to know how to connect WLC 9800 HA pair when RP is not back to back I mean RP port will be connected to VSS switch and they are in different rooms. My doubt is how I have to configure switch port to allow controller see each other and establish the HA.
generally in this scenario you need to create a dedicated VLAN for the RP connection/ Configure your switch port as access in this vlan and physically connect this port to RP. The vlan does not need to be unique in your environment but it is better to not use it anywhere else.
so if we have satellite server, device will communicate with satellite server for licensing. if we introduce dnac, does dnac download licence from satellite server and then dispatch it to switches. in terms of dnac report licence usage to cssm, is there any advantage over switches reporting it to satellite server directly?
Satellites act as a proxy and DNAC has a Satellite function built-in hence when you introduce DNAC you can retier satellite and let DNAC talk to CSSM and devices.

Great video. Very detailed.
Where do i download the html script please
the HTML will be specific to the content you want to display hence you need to write it yourself. There are many free tool that let you write HTML code with much know-how.

Yes they have macos and other operating systems, check the product page for confirmation
hello, this is what my switch gives me when I write the last command: " CISCOPOE(config)#ip http secure-server Failed to generate persistent self-signed certificate. Secure server will use temporary self-signed certificate. " Can you help me please ?
this is expected as secure servers require a certificate for client-to-server communication. Cisco devices have self-signed cert generated every time you bot up the device to facilitate web server requirements. The error you see, essentially tells you that very same behavior.
@@SDNTechForum I understand, but do you know what I need to do to be able to connect to my switch again please? Is there any manipulation or slight command?

I buy my nano s pluse and I connect it to my redmi pad se throw the provided c-type cable at srat all work good but then i update the firmware and then it seems no connection between the cold walet and the tablet does anyone facing this issue plz help , notes that i already made my key seeds and the flash work great just this what happens when i update the firmware
this is a typical issue with upgrades, use the desktop app to upgrade and if required restore apps using seed.

Can we add Cisco DNA as destination?
yes, CTB is integrated in DNAC now. From DNAC you can configure devices to send the flows to CTB and then create a rule in CTB to forward the flows to DNAC as destination.

both controller must be in the same net?
For Cisco Catalyst 9800 Wireless LAN Controller (WLC) redundancy, there are different deployment models, but generally, both controllers should be on the same network or at least have network connectivity with each other. This is to ensure that they can communicate for redundancy protocols like Stateful Switchover (SSO) to work correctly. There are two main redundancy models for the Cisco Catalyst 9800 WLC: 1. SSO Redundancy: In this mode, there is an active WLC and a standby WLC. The standby controller continuously synchronizes data and state information with the active controller. Upon a failure of the active WLC, the standby WLC takes over without requiring re-authentication of clients and access points (APs). For SSO to work effectively, both controllers must have direct IP reachability, which typically means they are on the same subnet or network segment to minimize latency and ensure reliable communication. 2. N+1 Redundancy: This is a form of redundancy where 'N' number of WLCs are actively managing APs and clients, and there is one additional WLC acting as a backup for one or more controllers in the event of a failure. In N+1 redundancy, the backup WLC can be on a different network segment, but it should still have network connectivity to the managed APs to take control of them if the primary WLC fail
