Hi Guys,

Will a configuration with multiple interfaces work with the following
entries in the dsc.conf?

interface eth2;
interface eth3;
interface eth4;
interface eth5;

For some reason the DSC data only looks like its gathering results for the
last one (eth5).

Thanks,

David

It is supposed to work they way that you want.  I think you should
be getting data from all interfaces, but its been a while since
I've tested such a configuration.

The code calls pcap_open() for each interface and then uses
select(2) on the pcap file descriptor to multiplex.

you don't have more than one 'bpf_program' line, do you?

If you re-order the interface lines do you then get only traffic
from the new last interface?

Hi,

No, I don't have a 'bpf_program' line, since the one we tried did produce any results.

I am under the impression that yes, we are only seeing traffic for the last interface on the config.

Subject: [dsc] multiple local addresses
Message-ID: <D6E0C667-B982-43BE-AAFF-312FAE1681A5@oakland.edu>

I am trying to specify 2 IPv4 addresses in dsc.conf, and the  
documentation says to separate multiple addresses with whitespace.   
However, when I do this, I receive the following:

complete failure
r123:
parse failure after 218 bytes, near 141.210.8.3;
local_address ::1;

# run_dir
#
#       dsc passes this directory to chdir() after starting.
#
run_dir "/usr/local/dsc/var/run/adonis-dhe";

# pid_file
#



the line in the config file looks like this;


local_address 141.210.8.2 141.210.8.3;
local_address ::1;




Anyone else with multiple address have any suggestions?  I currently  
tried this, however I'm not sure its working:

local_address 141.210.8.2;
local_address 141.210.8.3;
local_address ::1;



Thanks,

This form is not supported.  I didn't see where the documentation
says you can use whitespace separated entries on a single
local_address line.  Can you point it out out me?

You'll have to list each address separately, as you did here:

> local_address 141.210.8.2;
> local_address 141.210.8.3;
> local_address ::1;

The collector code uses a singly linked list to hold the local
address information.  That means you should be able to specify as
many as you need.

If you have some local addresses that receive more traffic than
others, you should order them starting with least popular to most
popular.
