The _ws.col.Info field sometimes contains double quotes ("). This is the case
for mDNS, and perhaps other protocols. This breaks CSV parsers, since they
recognize double quotes as the field delimiter. Note, using -E quote=d is
typically necessary when creating valid CSV from tshark many output fields from
tshark can contain a comma.
Sample of problem (note the "QM" inside the _ws.col.Info field):
tshark -T fields -e frame.number -e _ws.col.Protocol -e _ws.col.Info -E
separator=, -E header=y -E quote=d -Y "dns"
frame.number,_ws.col.Protocol,_ws.col.Info
"179","MDNS","Standard query 0x0000 PTR _googlecast._tcp.local, "QM" question"
"183","MDNS","Standard query 0x0000 PTR _googlecast._tcp.local, "QM" question"
Desired output:
tshark -T fields -e frame.number -e _ws.col.Protocol -e _ws.col.Info -E
separator=, -E header=y -E quote=d -Y "dns"
frame.number,_ws.col.Protocol,_ws.col.Info
"179","MDNS","Standard query 0x0000 PTR _googlecast._tcp.local, QM question"
"183","MDNS","Standard query 0x0000 PTR _googlecast._tcp.local, QM question"
I recommend ensuring that double quotes are never placed inside of a tshark
output field, to include the _ws.col fields. Is this an issue with the mDNS
dissector?
