Lets Encrypt 403 Error When Installing certbot-auto on legacy (EOL) SNI is required error

Asked 2022-Mar-29 at 12:54

Good day,

I am trying to create a test server with an EOL set up - Ubuntu 14.04, php5.5.

I am trying to install certbot-auto 1.9.0. I understand this is EOL and really shouldn't be used. However, we do have servers which are still using it successfully with little issues.

When I am trying to install certbot-auto 1.9.0 I am receiving the following error. Is there anyway to get around this issue?

According to this answer on the LetsEncrypt discussion board, it's not possible to use Certbot/certbot-auto at all with Ubuntu 14.04 anymore (likely because Certbot tries to update itself, and is no longer able to on Ubuntu 14.04).

acme.sh is a different LetsEncrypt client that possibly works.

running Powershell from ASP.NET Core 6

Asked 2022-Mar-21 at 10:05

I'm running an ASP.NET Core 6 application on an IIS as a Rest Api calling Powershell scripts for specific tasks. It works well from my laptop (Windows 10) but doesn't work when I'm running it on a Windows Server 2019 Version 1809 Build 17763.1935. The error tells me that it cannnot find the assembly "Microsoft.Management.Infrastructure".

Unhandled exception. System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Management.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Das System kann die angegebene Datei nicht finden. File name: 'Microsoft.Management.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

"Das System kann die angegebene Datei nicht finden." = "File not found."

Did anyone encounter that problem too? The server has the following things installed:

Microsoft .NET 6.0.3 - Windows Server Hosting Microsoft .NET Runtime
6.0.3 (x64) Microsoft .NET Runtime - 6.0.3 (x86)
Microsoft .NET SDK 6.0.201 (x64) Microsoft

Yaws webserver running via HTTP but not via HTTPS

Asked 2022-Feb-01 at 18:15

I have a yaws webserver. I'm trying to connect via https in local network. When I setup my server in yaws.conf for http, as follows, all works fine when I connect via http://0.0.0.0:80/myappmod in browser

...

ANSWER

Answered 2022-Feb-01 at 18:15

In your yaws.conf file, your keyfile parameter in the block refers to a file with a .key suffix. According to the Erlang ssl module man page, that file should instead be in PEM format (i.e., a .pem file).

The ssl man page says if you leave out the keyfile parameter, it defaults to the same as certfile, so you could try dropping keyfile from your yaws.conf file to see if that helps.
If that doesn't work, you likely need to convert the .key file to a .pem file; this answer describes how to do it.

Continuous cache-misses from Cloudfront when using HTML img tag, but getting cache-hits with Postman/browser requests

Asked 2022-Jan-25 at 19:28

I have a Cloudfront distribution with a S3 origin bucket (using Cloudformation/SAM to delegate resources) that's acting strangely. The S3 bucket only stores images.

Whenever I request an image through the src attribute, the network tab in dev-tools shows that the Cloudfront resource was a cache-miss (remains even after repeated refreshing). However, when sending a GET request through Postman or a browser, after one refresh I start seeing Cache-hits from the respective request sender.

Client-side, I'm using React with styled-components for the image tag. No query strings are being appended and Cloudfront has been told to disregard them as well.

Not sure if this is an issue with my Cloudformation setup or an issue with cached responses from the server, but any guidance would be much appreciated!

My template.yaml file:

ANSWER

Answered 2022-Jan-25 at 19:28

The issue was Chrome caching response headers for repeat-requests to resources.

Devtools shows a status code of 200 for the requested resource along with a (from disk cache) message- led me to believe that the status code AND the response headers were being cached. Tried clearing the browser cache and got the expected Cloudfront header.

BPF verifier fails because of invalid access to packet

Asked 2022-Jan-23 at 01:44

I am trying to get the server name from the SNI extension of a TLS hello packet in a XDP program. When I try to load it, I get the following error from the BPF verifier: invalid access to packet

...

ANSWER

Answered 2022-Jan-19 at 19:18

I think I have found the core of the issue. The verifier tracks a couple of properties about variables which allow it to determine if the program might access data it shouldn't. One of these properties is umax_value which tracks that the max unsigned int value is, which might be dynamic.

Since packets have finite size the verifier asserts that the umax_value of an offset into the packet may never exceed MAX_PACKET_OFF(65536).

Every time the program loops we add ext_len to data, since ext_len is a __u16 its max uint value is 65536 by default. The program limits this to 30000 with the following statement:

Pretty old. Based on the information I would assume Ubuntu 16.04 or similar.

The server supports only a few ciphers and none of these is in the default cipher set used by IO::Socket::SSL in this old version. To work around explicitly allow a broader set of ciphers using ssl_opts and SSL_cipher_list:
