Why tshark rocks
- more functions than tcpdump
- shares features with Wireshark
- lives in /usr/bin
- can capture to a ring buffer
- capture and read filters
tshark command lines
statistics
tshark -qz io,stat,0.01,ip.addr==172.17.23.1 tshark -qz conv,eth tshark -qz proto,colinfo,nfs tshark -qz sip,stat tshark -o "smb.sid_name_snooping:TRUE" -qz smb,sids
ring buffer capture
tshark -b 5 -a filesize:9728 -w mm.cap
read filter (live capture, read capture file)
tshark -r mm.cap -R "tcp.port!=50050&&ip.addr==172.17.23.5" -w clean.cap -R "not(ip.addr==172.17.23.5&&tcp.len==0)" -R 'pop.request || http.request.method==GET || http.request.method=="POST"'
capture filter (live capture)
-f not host 172.17.23.255
decode ports as specific service
tshark -d tcp.port==8888,http
