We are trying to use the tethereal colinfo option to 
append a couple of columns to the output. The columns we 
are specifically interested in are http.cookie and ip.len. 
But for some reason when specifying multiple 
colinfo options using -z colinfo, it seems that tethereal 
is parsing only one (seemingly the last one specified) 
option and ignores every other -z colinfo option. 
According to the documentation it is possible to list this 
option multiple times but this doesn't seem to be working. 
We are running ethereal version 0.10.10. Here's the exact 
command line we are 
using: 

tethereal -n -S -ta -f tcp port 80 -d tcp.port==80,http -z 
proto,colinfo,http.cookie,http.cookie -z 
proto,colinfo,ip.len,ip.len 

Any advice here will be greatly appreciated.
