Getting Detailed Error Info in IIS 7


Server Error in '/' Application.


Runtime Error


Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed.

Details: To enable the details of this specific error message to be viewable on the local server machine, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "RemoteOnly". To enable the details to be viewable on remote machines, please set "mode" to "Off".




<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="RemoteOnly"/>
    </system.web>
</configuration>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.




<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="On" defaultRedirect="mycustompage.htm"/>
    </system.web>
</configuration>


Solution

<configuration>

    <system.webServer>
      <httpErrors errorMode="Detailed" />
      <asp scriptErrorSentToBrowser="true" />

      <aspNetCore processPath=".\LibPrograms.exe" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout">
        <environmentVariables>
          <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Development" />
        </environmentVariables>
      </aspNetCore>

    </system.webServer>

    <system.web>
      <customErrors mode="Off" />
      <compilation debug="true" />
    </system.web>

</configuration>

Please note:
For Net Core apps:
1. ASPNETCORE_ENVIRONMENT must set to Development in order to display detailed errors
2. The highlighted rows are enough for displaying detailed errors

Use GnuPG Tools or C# Code for PGP Encryption and Signature

For PGP encryption and signature, usually we use PGP command line tools for test purpose and finally use C# application for production. Mine is a Net Core 2.0 console application using NuGet package PgpCore,  https://github.com/mattosaurus/PgpCore. PgpCore is based on BouncyCastle.NetCore which supports the standard OpenPGP keys. Here w use the popular GnuPG (GPG) tools to generate OpenPGP key pair. Download and Install GPG for Windows Download from  https://gpg4win.org/download.html . By default the installation will create two folders (here we use command line tools only): Gpg4Win UI (Kleopatra): C:\Program Files (x86)\Gpg4win Command line tools: C:\Program Files (x86)\GnuPG\bin Generate a GPG Key Pair For GnuPG 2.2.1 and above:     C:\Program Files (x86)\GnuPG\bin> gpg --full-generate-key For old versions of GnuPG:     C:\Program Files (x86)\GnuPG\bin> gpg --gen-key Common GPG Commands List public keys: gpg --list-key or gpg -k List private keys: gpg

Confusing Concepts about SFTP: SSH2 vs OpenSSH

Credit and copied from https://dada.tw/2008/01/03/70/ Terminology: SSH Protocols and Products SSH A generic term referring to SSH protocols or software products. SSH-1 The SSH protocol, Version 1. This protocol went through several revisions, of which 1.3 and 1.5 are the best known, and we will write SSH-1.3 and SSH-1.5 should the distinction be necessary. SSH-2 The SSH protocol, Version 2, as defined by several draft standards documents of the IETF SECSH working group. SSH1 Tatu Ylönen's software implementing the SSH-1 protocol; the original SSH. Now distributed and maintained (minimally) by SSH Communications Security, Inc. SSH2 The "SSH Secure Shell" product from SSH Communications Security, Inc. This is a commercial SSH-2 protocol implementation, though it is licensed free of charge in some circumstances. ssh (all lowercase letters) A client program included in SSH1, SSH2, OpenSSH, F-Secure SSH, and other
