Today I experimenting a very strange situation... An extender-AccessPoint from tp-link brand disables ports for a 9200 Catalyst switch with the error of "err-disabled" due to loopback error detected.. I updated the tp-link device firmware and still peoduces same behavior, this was a RE450 model but with RE455 doesn't happens so maybe some bads on code about specifications RFCs or whatever... maybe a bug in iOS Cisco firm but thats rare. Will capture some traffic to look for some culprit
Thank you for showcasing this! You nailed the name :) The CSV feature is just picked up to be worked on. We should have it soon. I will include this video in the README as well if you do not mind? p.s. you might find the `-r <n>` flag useful too. when pinging a hostname, if it encounters <n> amount of failures, it will retry resolving it and tries another IP address behind that hostname. This is useful in case of companies that have a bunch of IP addresses responding to a hostname.
thanks, i just saw that someone is going to work on it. too cool. my pleasure, and no problem including my video . i will gladly do a follow up video when the new features are added. and thank you for the -r option. i will include it in the update video and have been showing people in my training sessions as well as consulting gigs. regards
@@tonyfsvids Shoot. Well I found it very helpful so thank you for posting what you did. I'm currently trying to dig up a loop for a client with 18 switches and about 50 unman switches.
These videos are amazing. I have worked on CCTV for 10 years. Its mostly reboot or replace. I could never find anyone to show me how to troubleshoot CCTV cameras, it was always networks.
hub 6-0:1.0: config failed, hub doesn't have have any ports!(err-19). Showing like this. Also updated system graphic card and system by getting into nomodeset cmd but same problem while booting to linux. Device: laptop Lenovo loq gen 9 amd 7 7000 series 4050 rtx. Please someone help me to solve this
@@xgoranbrankovic thanks for the reply but I also tried many methods following all methods given by chat gpt also but same result. Now the only solution is to login with nomodeset kernal
@duvvadajagannadham-y2r Some quick ideas here is try updating your Lenovo BIOS to the latest version. Only have 1 usb device connected and test accordingly. If those options fail, try using an older Kali Linux and see if that succeeds. Thanks for viewing.
Great tutorial! The step-by-step instructions made setting up a dual boot with Windows 11 and Kali Linux super clear. Thanks for breaking it down so well!
Make sure you have enough free space on your drive. You need to partition a portion of your drive for Kali Linux (about 20-50 GB or more depending on your needs).
This is the perfect guide for setting up a dual boot! Windows 11 and Kali Linux running smoothly together is a game-changer for anyone diving into cybersecurity. Thanks for breaking it down so clearly! #TechMastery #DualBootSuccess
Hi Tony. I am very new in iperf and don't understand your point about downloading and uploading [speed](ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZUTx2t9tmK4.html). Could you please explain how you measure those? Thanks!
welcome and thanks for the question. upload and download tests can identify if the receiver, the port or Wifi has issues. for example if the access point has an awesome antenna and radio your downloads might be higher than your uploads, same with half duplex/full duplex mismatches.. doing just an upload or download only gives you half the picture. hope that helps
This video provides an excellent guide for setting up a dual boot with Windows 11 and Kali Linux. The step-by-step instructions are clear and make the process seem straightforward, even for those who are new to dual booting.
After exploring available macOS tools, if you open the Wireless Diagnostics app and go to the Window menu, then choose Scan, you get similar output (i.e., BSSID, RSSI, Security, etc.). As for a replacement AP, check into MikroTik hAP devices, which are highly-configurable and have perpetual licenses.
Consultants have very little say on huge builds. The company that gets the construction contract deals with all the contractors.. I am simply told what to do
Hi Tony, Upon closer inspection, I noticed that each BSSID MAC address is indeed unique. It seems the access point might be inadvertently broadcasting its default SSIDs. If you'd like to keep using the current access point, I recommend factory resetting it and reinstalling the firmware (possibly an older version). Then, manually recreate the configuration to rule out any corruption. However, if you're looking for a quick solution or prefer a different approach, a WiFi 6 (802.11ax) access point from Unifi could be a good option. They're affordable and can be easily set up as standalone units without a controller. I'd suggest the Unifi U6-PRO unless you have specific requirements. I personally use three of them at home, and they've been working great. Please let us know how you get on.
thanks for the comments.. in this case you are correct, but other times, the mac are all the same. i have tried resetting back to factory and going back a rev.. I'm a big ubnt fan and have deployed hundreds outside for my ISP and plan to get an U6 soon i just purchased 8 u6's and 4 outdoor for an install and look forward to playing with it..
I can't believe you're facing the same problem as I am. I noticed that this also happens on ZTE routers, but it only occurs after the router has been off for 15 minutes to 1 hour.
Dual booting Windows 11 and Kali Linux can be beneficial, allowing you to take advantage of the tools and software of both operating systems. Make sure you have it fully installed beforehand.
Make sure your computer is capable of running both Windows 11 and Kali Linux. You need to have at least two empty or unpartitioned hard drive partitions to install Kali Linux.
Hi. How you doing? i really liked the videos you have upload about networking, nmap and etc.. i would really like to contact you because right now im facing troubles with nmap and wireshark packets and i do not know how to solve it. I would like you to give me a hand with this. Hope you will be able to contact me back
