Re: Adding DSCP column in Wireshark 1.4.0rc1

---- I think my question is similar to the question of Keith titled "Adding DSCP column in Wireshark 1.4.0rc1" ----

I'm using Tshark to read a PCAP file. It filters the DNS queries that took longer than 1 second. This is the command:

tshark -r inputfile.pcap -R "dns.time > 1" -T fields -e dns.resp.name -e dns.qry.type

The part of dns.qry.type shows hex values instead of readable results. This is an example:

faststone.org   0x0001
microsoft.com   0x001c
uucp1.xs4all.nl 0x0001

When I add the same value as a collumn it works fine and displays either A or AAAA. Which is good.

Is there a way to force Tshark to do the same?

Thanks,

Dave

  I want to add a column for DSCP, but in V1.4.0rc1, when I right click on the DSCP field and select "Apply as column", 
it uses the filter ip.dsfield.dscp. However, this displays the verbose DSCP value e.g.  "Differentiated Services 
Codepoint: Expedited Forwarding (0x2e)". 

  Is there a way to force the column to display just the decimal value (46) of this field? I am sure that in 1.2.8 this 
filter used as a column did display just the decimal value.
