Send me pcap file on email ikheifets@splunk.com

@mccain007 without pcap file (with log messages that producing your device) we can't implement parser for you. We need to know format of log message

Understood I was trying to get the pcap from the admin for mguard but he hasn’t replied

Hello, @mccain007 ! I need raw logs that producing your device, send me please pcap file and I will open your pcap in WireShark.

Without raw message we can't implement parser, we need to know log format to implement that. I already mentioned https://github.com/splunk/splunk-connect-for-syslog/issues/2435#issuecomment-2102831559

problem of your tcpdump output that we can't see here raw log content. Please use official guide

ikheifets-splunk commented 1 month ago

@mccain007 I closing this issue, because you haven't provide me pcap file, and I waiting for it month. When you will provide I reopen this issue. You know that without examples of your log message impossible create a parser
