[Netsplitter-question] FASD project: Online survey launched

[<ben...@id...>]

Dear Open Source developer

I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate.
You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it.

With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development.


With many thanks for your participation,
Benno Luthiger


PS:
The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/.
We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_en.html for registration to this mailing list.

[Netsplitter-question] quick query..

[Chris B. <cb...@hi...>]

Hello!

I've recently donwloaded a copy of netsplitter (netsplitter_20021204), =
compiled it with make linux, make install and have been using it fine =
for a a day ro so but now all of a sudden it seems to have broken =
itself, well either that or some config has gone haywire.

I've got 2 adsl speedtouch modems both on a 512kbs line, the ip address =
of one is 81.130.3.11 and the other is 81.130.21.112

so I've setup the config file thus..
INTERFACE ppp0 81.130.3.11 500 1
INTERFACE ppp1 81.130.21.112 500 2
PING 81.130.3.11

The config file I've got for setting up all the iptables stuff is...

iptables -P INPUT ACCEPT
iptables -F INPUT
iptables -P OUTPUT ACCEPT
iptables -F OUTPUT
iptables -P FORWARD DROP
iptables -F FORWARD
iptables -t nat -F

iptables -A FORWARD -i ppp0 -o eth0 -m state --state ESTABLISHED,RELATED =
-j ACCEPT
iptables -A FORWARD -i ppp1 -o eth0 -m state --state ESTABLISHED,RELATED =
-j ACCEPT
iptables -t nat -A POSTROUTING -p ICMP -o ppp0 -j MASQUERADE
iptables -t nat -A POSTROUTING -p UDP -o ppp1 -j MASQUERADE
iptables -t nat -A PREROUTING -i eth0 -p tcp -s 10.0.0.0/24  -j DNAT =
--to-destination 10.0.0.152:5122
echo done.

The ICMP & UDP stuff might be wrong im not sure but tcp is the main =
concern at the moment.

netsplitter.log contains

[Fri Sep 12 09:05:51] [STATUS] [ppp0] ONLINE - PING: 0.000096 ms
[Fri Sep 12 09:05:51] [STATUS] [ppp1] ONLINE - PING: 0.000139 ms
[Fri Sep 12 09:05:51] [INIT] Interface: [ppp0]
[Fri Sep 12 09:05:51] [INIT] Interface: [ppp1]

I think thats it for the logs & config.  The problem is that for =
instances when I'm checking my mail on a machine on the network, it will =
connect and then time out.  I suspect its telling me its connected =
because its connected to port 5122 on linux machine but it times out and =
web browsing etc is not possible.  When it was working it was great, =
downloading files on kazaa etc with speeds up to 100kbs :)

Carry on the good work and any ideas?

Cheers,

Chris

Don' t forget the --sport command, they are required for LOCAL nat.


In README:
----------------------------------------------------------------------------------------------------------------------------------------------------
In your iptables rules:
iptables -t nat -A OUTPUT  -p tcp --sport 1024:4999 -j DNAT 
--to-destination 192
.168.1.1:5122

where 1024-4999 are the values in /proc/sys/net/ipv4/ip_local_port_range.
and 192.168.1.1 is the netsplitter address.

[Netsplitter-question] netsplitter dies: too many files open

[Edward v. K. <ed...@ni...>]

Hi

Firstly, by the way, I can't see the mailing list archives? 
The link: http://sourceforge.net/mailarchive/forum.php?forum=netsplitter-question
doesn't seem work.

Secondly, I can't get netfilter to work, yet it is JUST what i need.
Maybe someone could help me?

I compiled and installed it. I run it at the command line as
"netsplitter -v 1"

I ran: 
	iptables -t nat -A OUTPUT -j DNAT -p tcp --dport 7777 --to-destination 196.7.14.3:5122

The machine doing the netsplitting is 196.7.14.3
As a test, I'm trying to connect to 196.7.14.16 on port 7777.

On 196.7.14.16 i run "netcat -l -p 7777"

On 196.7.14.3 in run "netcat 196.7.14.3 7777", but it justs returns to the command line.

proxy:~# netcat 196.7.14.16 7777
proxy:~# netcat 196.7.14.16 7777

The log shows lots of these:
[Mon Mar 03 17:55:40] [DEBUG CONNECT] 196.7.14.16 -> ppp0
[Mon Mar 03 17:55:40] [DEBUG CONNECT] 196.7.14.16 -> ppp1
[Mon Mar 03 17:55:40] [DEBUG CONNECT] 196.7.14.16 -> ppp0
[Mon Mar 03 17:55:40] [DEBUG CONNECT] 196.7.14.16 -> ppp1

But after several attempts, it bombs out, like so:

proxy:~/netsplitter# ./netsplitter_20021204/netsplitter -v 1
Setting debug level = '1'
/var/log/netsplitter.log: Too many open files
/var/log/netsplitter.log: Too many open files
/var/log/netsplitter.log: Too many open files
/var/log/netsplitter.log: Too many open files
/var/log/netsplitter.log: Too many open files
socket->out: Too many open files

Can anyone help me?
