FTP Access Denied When Attempting to Transfer Files

Permission is, as usual, a double-edged sword. It happened when I tried to transfer files to a remote Linux server.

I created a directory on the remote server and attempting to transfer files via FTP client but got an access denied error. It is weird because I do login using the same account and thus as the owner of the directory.

The one that solves the problem in my case is by changing ownership of the folder recursively (-R option) and use name of the user as group name such as:

sudo chown -R <user>:<user> <directory>

Sentinel One Strikes Again. No internet connection. Uninstall Sentinel One Agent.

This happened to a co-worker of mine a while back when his test application file was marked as suspicious by Sentinel One antivirus and had his internet on his laptop disabled. Today, it happened to me without any suspicious file. Probably suspicious activity, who knows. On Microsoft Edge, it says "Hmmm... your Internet access is blocked.", "Firewall or antivirus software may have blocked the connection", and "ERR_NETWORK_ACCESS_DENIED". So, I worked with my IT to uninstall the agent, but uninstalling is not without a fight. Here are the steps that I took: Since it is a Windows 11 machine with Bitlocker, I have to first get the Bitlocker key.

Then go to system configuration by searching for "sysconfig" or run msconfig. Under "boot" tab, check the "Safe boot" option, then click ...

A2 Hosting Let's Encrypt Can't Install Certificate on ASP.NET Core Application

I have an ASP.NET Core app hosted by A2 Hosting. A2 Hosting provides free SSL certificate through Let's Encrypt, so I decided to install it for my application. Since the portal is by Plesk, I follow the guide in: https://support.plesk.com/hc/en-us/articles/115000165013 However, it didn't work as expected. My application still has a web.config file. After trying different ways, I commented out aspNetCore module in the web.config and then the certificate was installed successfully. By commenting the module, ASP.NET Core processing by IIS is disabled, so the validation request by Let's Encrypt is treated like a regular request towards a static file.

NuGet Package Reference NU6105 Publish Error

Some of my .NET Core applications are already using PackageReference which is a very nice idea. However, through a combination of packages, Visual Studio did not allow me to publish my project although it built fine. During publish, it threw error on NU6105 warning. Along with that most of it comes with the following message: Detected package downgrade Some developers solve it by finding which package caused the issue and manually added them through NuGet, but I find them troublesome until I found the following article: https://docs.microsoft.com/en-us/nuget/reference/errors-and-warnings/nu1605 In my case, all I need to do to solve it is to install the following NuGet package:  Microsoft.NETCore.Targets
