Over the Christmas break, I had a few hours to spare and tackled a few issues in some of my PowerShell modules. I’ve released Posh-SYSLOG 3.2 as a resolve of this.
This version removes the need to call Get-NetAdapter that's contained in the NetTCPIP module. The reason why I wanted to remove this dependency is to allow Posh-SYSLOG to run on PowerShell 6 (at least on Windows to start with).
An issue has been reported on GitHub, Ben Claussen has identified an issue with the timestamp for RFC3164 messages. The fix appears to be simple, but I'll want to do some more through testing. I'm hoping to have this fix out in the next week as version 3.2.1.
