Hi Darragh! Here is the tcpdump data, from the following commands:
--- ip netns exec qrouter-41b95614-abbc-4c55-916c-7494adc37a0b tcpdump -v -n -i qr-b5725a2c-f1 -w qr-b5725a2c-f1.tcpdump tcpdump: listening on qr-b5725a2c-f1, link-type EN10MB (Ethernet), capture size 65535 bytes 22916 packets captured 22916 packets received by filter 0 packets dropped by kernel - ip netns exec qrouter-41b95614-abbc-4c55-916c-7494adc37a0b tcpdump -v -n -i qg-a1a1a364-c0 -w qg-a1a1a364-c0.tcpdump tcpdump: listening on qg-a1a1a364-c0, link-type EN10MB (Ethernet), capture size 65535 bytes 23120 packets captured 23120 packets received by filter 0 packets dropped by kernel --- Within the Instance, I executed: ## tcpdump started at the Network Node: ping -c 10 google.com # tcpdump counter: "Got 24" qr- int, "Got 29" qg- int aptitude update # it took about 9 minutes to finish... Minimum accepted is about 1 minute/max. ## tcpdump stopped at the Network Node, files attached here. --- NOTE: During the "aptitude update", the download speed hits "0 B/s" a few of times AND, every time the "aptitude update" was waiting for the network to "wake up", the two tcpdump instances was stucked at: * outage #1: tcpdump of qr- interface stucked at: "Got 15446" tcpdump of qg- interface stucked at: "Got 15489" * outage #2: tcpdump of qr- interface stucked again at: "Got 16139" tcpdump of qg- interface stucked again at: "Got 16212" * outage #3: tcpdump of qr- interface stucked again at: "Got 17527" tcpdump of qg- interface stucked again at: "Got 17661" * # 4 - finished tcpdump of qr- interface finished at: "Got 22912" tcpdump of qg- interface finished at: "Got 23120" # tcpdump stopped, files attached here. --- Hope it helps! Cheers!
