Inspecting the captures a bit more closely, I see that OS X sets the DSCP field in the IP header to 0x48 for SSH traffic - as does OpenBSD in its replies. Linux sets this value to either 0x00 or 0x10 as does Windows for SSH. OS X seem to tag iperf traffic as 0x00 as well. I wonder if I'm running up against some QoS issue but AFAIK I have QoS disabled everywhere. Can I use pf to tag egress traffic as 0x00 and see if it goes away? The issue is intermittent which makes me think it's congestion related. Regards Lloyd
