QUESTION
Warning: PowerShell-newb at work.
I got a .csv-file that I am trying to filter and split in different parts. The data looks s.th. like this (much more columns in real)
...ANSWER
Answered 2021-May-21 at 04:13Your code sample handles multiple input files. You seem to understand the file I/O but as the commenters have already noted, you are not making use of the built in CSV and Object processing within PowerShell.
First we'll read your sample data from a here-string for simplicity and to make the code below easy to test
QUESTION
i read all the relevant threads on the error "The request was aborted: Could not create SSL/TLS secure channel" but none was applicable to my case.
I have a set of code that is executing against the Splunk HTTP Event collector REST API. if i execute the exact same code from a console C# app locally on my box, all works great.
When i execute it inside a WCF service it fails with the error above. Since the certificate Splunk Light Cloud service uses is a self-signed cert, i set up the following prior to executing my code.
...ANSWER
Answered 2017-Feb-10 at 01:50I was finally able to solve this and updating this page for future folks. In trying to understand the issue, i concentrated my investigation in 3 areas that could possibly cause the response of an IllegalMessage (Win32 SChannel Native Error Code: 0x80090326)
- Did the Splunk site use ECC (elliptic curves cryptography) in their certificate and my server could not support it
- Was SSL renegotiation not working
- Did the ciphers my computer was producing not matching the certificate expectations
wireshark and microsoft message analyzer helped a little bit, but since I did not have the private key of the Splunk certificate, i could not decrypt a lot of the content. Fiddler, with the man in the middle proxy, gave me some useful data as well.
Eventually, #1 was not an issue. #2 was an issue and I discovered https://support.microsoft.com/en-us/help/2745582/.net-framework-4.5-hotfix-resolves-httpwebrequest-and-sslstream-issues. With that in mind, I updated my computers to .NET 4.6.2
Once I got past all the other issues, #3 became my problem. According to this article, https://technet.microsoft.com/en-us/library/dn786419(v=ws.11).aspx, Windows Server 2012 R2 and Win2k16 support the same TLS and cipher suits. After lots of debugging, i discovered our domain policy had a group policy that restricted the ciphers available for use and demanded a specific order depending on the Operating System you were using. After manual trial and error, I was able to pinpoint the exact 3 ciphers needed by the Splunk Light public endpoint for HTTP event collection:
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA_P256 TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA_P384 TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA_P384
the fact that was i executing the code from a WCF service ended up playing no role in this.
