[netsniff-ng] Synchronize file creation between netsniff-ng processes possible?

Hi everyone! I've googled a bit but not found any good answer to my question. Maybe you can help me out? Currently I'm running five netsniff processes capturing data from five different interfaces. It works really well with the limiting factor SSD write speed, not netsniff itself. To make

[netsniff-ng] [PATCH v3 08/16] trafgen: parser: Add syntax to generate Ethernet header

Add syntax for generating Ethernet header fields like: { eth(prot=0x0800, da=11:22:33:44:55:66), fill(0xff, 60) } { eth(prot=0x0800) } { eth() } It is important that proto_init is called before fields will be filled to initialize the specified proto with header fields.
