Troubleshooting Wireless Port Issues
Dear All, Currently I am facing an issue with connectivity and ports issues with my broadband, especially for applications that mandate certain ports to be open. While trying to troubleshoot this issue, I found a port diagnostics tool PortChecker.dev which was really helpful. PortChecker.dev is particularly useful for users having problems with port forwarding, port blocking, or obsevring whether a specific port is open for their broadband. The website is user-friendly, as no additional software installation is required in order to test the ports. This is how it works: You simply enter the wanted port you want to check, for example, port 80, 443, or any custom port. The system will determine if the port is open, closed, or filtered, helping to diagnose network based problems. For anyone dealing with online gaming, server hosting, or even troubleshooting broadband connectivity issues, it’s a perfect tool. If you are facing any of the above network trouble, make sure to check this out! For further information, just go to PortChecker.dev. If any of you have used similar tools or have any tips to boost broadband and wireless networks, please do share!
One rogue VM (secondary) account in a cluster of other VM accounts refuses to work.
I have one VM account (one of several secondary accounts) which has refused to accept input for some weeks. Thunderbird is email client. Up to 28th May VM/ThunderBird had worked without issue across a score of accounts on Ubuntu 22.04 desktop. There are no signs of email bouncing. They are swallowed now by this black hole account. I have tried changing rogue account password to no avail. Utter confusion in navigating VM links and ThunderBird dashboard probably screwed up other accounts. I also have ThunderBird on Windows (dual boot which I rarely use). I cannot get into VM server through ThunderBird Windows which I just tried. I am back in Ubuntu as I pen my journey through VM and ThunderBird. I can forward locally from one VM account to others. But just NOT to this particular rogue account. What I would like to do is apply a single password to every account (seen from Ubuntu and later Windows). Once all accounts (a score of accounts) are working I can if necessary apply unique password per account. But I will need to write an automation script (later) for this workflow. There is further complication since I am asked now to use a non VM email account for verification. So Gmail accounts (seen in ThunderBird alongside VM) are used. I read a tip in this forum to test email accounts using curl. I have started writing a multi account curl script for this quick analysis on a batch of accounts but right now I just need this rogue account to come back into service. Any VM/ThunderBird forensic users here to offer advice? Any VM “MRI scan” available? How are multiple passwords synced between VM and Thunderbird? I would like a one stop shop for multi account administration. Further Thoughts. Added note: This particular secondary VM account had worked for some time. Then I used it as an MX forwarding address from a domain in construction. Google Domains transferred their global estate of domains to SquareSpace and whether concidental or not my problems occurred then. I have since deleted domain MX records forwarding rule for that domain which pointed to this non receiving secondary account. And I am looking back through the correspondents I can view in archived profile so that I can systematically isolate this secondary account and perhaps delete it after I have extracted profile for backup and perhaps import to another account. There are multiple actors in play. SquareSpace, VirginMedia, ThunderBird.
