10 ip.addr == 192.168.67.83
14 No. -> generated while monitoring
16 Source IP (192.168.67.83), Destination IP (192.168.67.37), Protocol (UDP), Length (82), TTL (64), Dest port (118), Flags (empty), Frag offset (0)
22 repeating transfers, transfers seem separable over time via the udp.srcport attribute
24 filtered traffic via wireshark again by source port 51899
28 reimported to rapidminer
31 dscp + timing changes.
33 the DSCP value grows until 10962
35 then it's fixed on DSCP 10962
44 some bits are broken, as the timing and my decodes is more a hack.
46 a hack is a hack is a hack ... :)
51 filtered away nfs and ssh
52 !(tcp.port == 666 || tcp.port == 2049)
55 look at it via rapidminer
58 ((ip.addr eq 192.168.67.81 or ip.addr eq 192.168.67.82 or ip.addr eq 192.168.67.83) and ip.addr eq 192.168.67.37)
61 look at it again via rapidminer
62 image:stream\_better.pdf
64 dest ports are always first 80/udp, then 443/udp, then 465/tcp
66 filtered for one complete transaction
67 tcp.port == 56533 or udp.port == 50293 or udp.port == 56040
70 look at it again via rapidminer
71 image:stream\_cool.pdf
76 No. -> generated while monitoring
78 TTL (64), Frag offset (0)
81 does not look like timing, packets arrive in almost equal distances (10ms sequence)
87 0x0018: ACK,PSH (600x)
90 Expected distribution of values
93 not a high variance detected:
95 \item UDP Stream from 192.168.67.83:56040 to 192.168.67.37:80
96 \item UDP Stream from 192.168.67.82:50293 to 192.168.67.37:443
97 \item TCP Traffic between 192.168.67.81:56533 to 192.168.67.37:465
100 Length also does not vary very much:
102 \item Length 60 for Source Port 56040/udp
103 \item Length 60 for Source Port 52093/udp
104 \item Length 70 for ACK,PSH (600x), 74 for SYN (1x), 66 for ACK (1x) and 66 for FIN (1x) for Source Port 56533/tcp
105 \item Length 66 for ACK, 74 for SYN,ACK for Source Port 465/tcp
109 Unknown, because we do have two shorter transmissions before a longer transmission from different source ips
112 Not yet. We do not know if the three transmissions are connected to each other
