[ANet-devel] 16:00 GMT will be 12:00 EDT...

[Benoit N. <be...@ma...>]

Uhh... One small error. The meeting is at 16:00 GMT, which means 12:00 EDT
(eastern daylight saving time), _not_ 11:00 EST (eastern standard time).
That's because we will move from EST to EDT tomorrow, April 1st, at
12:00 AM (0:00). This will affect me, Chris and Quentin.

So, this means that I may miss the first 30 minutes or so of the meeting,
as I will need to eat.

[ANet-devel] HUGE site update!

[Benoit N. <be...@ma...>]

First, the is now a "private" part to our site:
http://anet.sourceforge.net/private/
To have a user name and password, log in to anet.sourceforge.net in ssh,
and do this:
htpasswd -m /home/groups/anet/site_passwords username
Where "username" will be your user name. DON'T USE SOURCEFORGE'S PASSWORD!
Just make up a low-security one (but not something like "password"...).

Also, thanks to Quentin, the whole site has a "menu" at the top-right.
Browse around the site: a made a summary of what the pages will contain
when they will be filled up.

Finally, I started (almost finished, actually), the document "Distributed
Networking". You really should read that.

Oh! I almost forgot! There's a forum too! To have a login/password, you
have to do something like in /home/groups/anet/cgi-bin/forum/cgi-bin/pwd.
Use the "benad2" file as a template. The file name is the login name, the
first line is the password, the second line is your real name, third line
the email (don't worry: you have to login to be able to see emails form
logged in users), 4th and 5th lines empty.
You'll need a good browser (NS4+, IE4+, iCab) to use it.
Tell me if you find a bug.

There's still some work to do (for example, a "last modified:" whose output
is the same size as the tag, and looks good; better CSS for the forum;
the site checker is screwing up with menu.cgi...), but that's enough for now.

Re: [ANet-devel] Coding: What You Can Do

[Quentin S. <que...@co...>]

Hi-
There should also be a way to manually set your IP address. Here is some 
perl code that can find your outside IP if you are behind a firewall. I 
am behind a firewall, but I can set the firewall to route unidentified 
packets to my computer, so this is useful.

use LWP::Simple;
sub getIP() {
#www.dyndns.org = 207.127.235.88 as of 7/30/00
#$IPtxt = get("http://207.127.235.88:8245/cgi-bin/check_ip.cgi");
#Now using upsys.be:
#upsys.be = 213.61.13.10 as of 8/29/00
$IPtxt = get("http://ubsys.by/dyndns/check_ip.php3");

$IPtxt =~ /Address: ?([0-9.]*)/;
$ip = $1;
if (wantarray) {
$IPtxt =~ /Hostname: ([^\n]*)/;
$name = $1;
return ($ip, $name);
}

Please beware of line breaks from email.

Actually, the default routing interface can be anything you want.
For modem users, it is ppp0. I can't assume that the computer is
connected to the internet through its ethernet card.
Look at the "route" command to see what I mean.

Most programs never ask you "what is your default routing interface?.
So, I know that there is a way to do it, and it would make our deamon
much more user-friendly, instead of "write the interface in the .anet file"...

No. Just something other than "cout" or "printf". From what I know, when
you output something, it is to some terminal device, which, in turn, may do
fun things like colors, highlighting and so on for displaying text on
screen. It's because, usually, scanf is blocking, and you can't call printf
until the user press return. So, basically, I'd like to be able to do
screen output like vim does on the terminal(with color, bold characters...).

Re: [ANet-devel] Coding: What You Can Do

[Chirag K. <ch...@ya...>]

hi benoit!

afaik, the default ethernet interface on a linux machine is always
"eth0". somebody, please correct me, if i'm wrong. the snippet which
you'd sent a few days back should do very well for this. the snippet
checks for command line args and if there are none, then prints all the
interfaces with their IP addresses and if the interface is specified
(for eg, "eth0"), then it will print the IP address of only eth0.

i am not sure if i got you on the second task. you mean you need an
editor to write to a device? i am not sure what do you mean by "text
device"; if it's serial port, then i suppose minicom kind of tool
should do fine.

[ANet-devel] Web Site Update

[Benoit N. <be...@ma...>]

There has been a small update to the web site this weekend. Actually,
there's been a lot of changes behind the scenes.

One of the most important changes is that you will need to place this tag
on each page (exactly; use copy-paste):
<!--#include virtual="/cgi-bin/ratlog.cgi" -->
This will allow the cgi script to effectively track the visits to the web
site. Look at http://anet.sourceforge.net/_old/reports/ to see what I mean.

You don't need to name the files "*.shtml". Just make sure that each time
you upload some pages to the site to execute the script
"/home/groups/anet/cgi-bin/install-anet.bash" from ssh.
Also, make sure that no file have their name ending with "*index.html"
unless it is exactly named "index.html".

The "install" script will also check all the external links. Look at
http://anet.sourceforge.net/_old/sitecheck.html.

If you have any comments about the web site, tell me.

(Hehe... I'll know which one of you will visit the web site...)

- Benad

[ANet-devel] Coding: What You Can Do

[Benoit N. <be...@ma...>]

While we haven't started the _real_ coding yet, here's a list of what you
can start right now.

1. Find a way on Linux to get the IP address of your machine, i.e. the IP
address of the default routing interface. If you just want to do some
copy-paste, make sure it comes from a project distributed under GPL.

2. Find some tools or methods to do non-blocking input and input to a text
device in Linux. A bit like emacs or vi. That would really help.

- Benad

[ANet-devel] IP address and Web Site Update

[Benoit N. <be...@ma...>]

Ajaya gave me this address for the "problem" of finding your IP address in
Linux:

http://sourceforge.net/snippet/download.php?type=snippet&id=100248

Somehoe, it doesn't work on my machine. So, I searched by myself and I
found this:

http://sourceforge.net/snippet/download.php?type=snippet&id=100318

Seems much more better (it worked), but you still have to find the default
interface (as with the shell command "route"). Anyone has any idea?


Now, the Web Site. I just updated it with the doc "Peet-to-Peer
Networking". Send me your comments (through this mailing list) if you have
any.

- Benad

[ANet-devel] Good Gnutella Analysis

[Benoit N. <be...@ma...>]

http://www.tch.org/gnutella.html

The math seems good, but some assumptions are not fully explained ("the
network is fully balanced"???).

Also, it contains some links to other good Gnutella papers.


BTW, I'm starting, little by little, the web site.
If you make some docs, just add the link in the "Site Index", and maybe add
a link to your doc in the main page (index.html). Don't forget to include
the small SourceForge banner to ALL the pages! The HTML for that is already
there, just copy-paste.

One last thing. Always do "chgrp anet theFile.html" and "chmod 664
theFile.html" to all the files you upload to the web site
(/home/groups/anet/htdocs/).

- Benad

[ANet-devel] Web Site Structure

[Benoit N. <be...@ma...>]

Here's how the web site should look like.
Again, if you have any question/comments/flames, tell me with this mailing
list.

It basically works like a directory.
I don't like SourceForge's forums, and we (me, Chris and Gaps (another
guy)) made a cool Perl-based forum system we could use.

Uhhh... No. Quenten, or anyone, you can try to build an empty web site that

I already started to write some text (from scratch, not like the "old"
docs), so feel free to start when you have some spare time.

[ANet-devel] BWHAhahaha.... They're SO screwed!

[Benoit N. <be...@ma...>]

First, look at http://www.peer-to-peerwg.org/.
Then, click on "Download".
You're now here: http://sourceforge.net/projects/ptptl/.

Now, look at the Trove Category. Nothing.
But a file was released...

Hmmmmm... You're not supposed to do that... I've seen several projects
closed because of that... But then, the staff is busy with the
"conferences"...

BTW, you don't have to download it. There's not much to see. It's just
Intel some of its internal libraries, which suck BTW.

Why C++ for *THAT*?

- Benad

[ANet-devel] First Checkin...

[Benoit N. <be...@ma...>]

Good news: I did my first checkin!
The bad news is, the code almost doesn't work. The files are in
ANet/ANet_Deamon/Linux.

Here's a "crash course" on CVS.

First, do this:
In csh:  CVS_RSH=ssh
In bash: export CVS_RSH=ssh

Then, (here, replace 'benad' with your user name in sourceforge)

To checkout:
cvs -d:ext:be...@cv...:/cvsroot/anet co -P Documentation
cvs -d:ext:be...@cv...:/cvsroot/anet co -P ANet

To checkin:
cd ANet/ANet_Common
cvs -d:ext:be...@cv...:/cvsroot/anet ci SomeFile.c

To add a file:
cd ANet/ANet_Common
cvs -d:ext:be...@cv...:/cvsroot/anet add NewFile.c

Notice the "-P". IT'S REALLY IMPORTANT! Remember, we can't delete a CVS
directory, and we don't have ssh access to the CVS servers. So, if you make
a new directory and you want to delete it, YOU CAN'T! So? Every empty
directory should be considered "deleted" (hence the "-P"), and I placed
some ".something" files in directories that are empty but that may be used
later. (Man... What a day...)

I'll send you later this week a pretty cool C-Shell script that set up
everything , i.e. to stop having to type your password for each CVS
command, or when you use "ssh" or "scp".

For now, here's what you (yes, you!) can do:
- Figure out how the client can use scanf and printf at the same time.
- Clean up the TCPIP code in the server.
- Place proper file headers (the comments at the beginning of the file).
- Move client.c to the ANet_Client_SDK directory.
- Make some header files.
- Move TCPIP code to the "TCPIP" directory (for the TCPIP module).
- Move IPC code to the "Client_Interface" directory.

Until the end of this month, I'm off to documentation. Anyways, it's time
everyone starts to understand my docs and the logic behind them...

So, try to use CVS, but don't screw up our account.

- Benad

[ANet-devel] Big, Fat, Miscellaneous Update

[Benoit N. <be...@ma...>]

First, here's what I'm doing.
At maximum next Monday I'll do my first CVS checkins. It won't have much,
but the files will have the proper headers, code style and so on. I'll try
to basically merge my code for ICP with Chris's code for TCP/IP, but don't
expect much (queues will be implemented later, the server won't be a "true"
deamon like what Ajaya did, and I'll stick to wait(1)...).

So, next week, I'll ask everyone to start testing CVS, both by doing
checkouts and checkins (add small comments like: "//this is a test by
Benad:"). Just don't do any crazy things like merges, branches and so on.
I'll post here how to use CVS once I'll personally remember how it works...

Ajaya, or anyone else, if you have ANY idea how to get your IP own address
(the primary one) in Linux, tell Chris. It will help him keep his sanity...


OK. Every two weeks, we should have some kind of real-time meeting. If you
have ANY idea about the technicalities of that (when, where and how), tell
me via this mailing list. I know, some of us are in India, other in
Germany, so it might be a bit complicated...

My ICQ number is 54325132, and I'll try to use it as much as possible.
Be sure to identify yourself correctly when asking for my authorization.


After I'll do the first checkins, I'll work exclusively on the Web site.
I'll tell each of you what you can do during that time.

Re: [ANet-devel] Got some TCP/IP code for Linux?

[Benoit N. <be...@ma...>]

>Hi-
>Could you please give instructions to connect to the project's CVS

DO NOT CHECKIN IN CVS YET! I will do the initial checkin next week.
For now, just upload the files to the ftp server.
Here's how to do it:

scp -aqvC -c 3des myFile.c be...@an...:myFile.c
(change "benad" for your login name). This will upload "myFile.c" to your
home directory ("cd /home/users/benad"). Then,

ssh -v -l benad -c 3des anet.sourceforge.net

Once you're logged, do this:
cd /home/groups/ftp/pub/anet

You are now at the "root" of the ftp server at
ftp://anet.sourceforge.net/pub/anet/

You should be able to make directories and move your files there.
Make sure that the files are readeable by all, and that directories
are writeable by the group ("users"), and read+execute by all.

If unsure, send me the files by email.

[ANet-devel] Got some TCP/IP code for Linux?

[Benoit N. <be...@ma...>]

If you have any TCP/IP code for Linux, upload it to the ftp site, or send
it to me. I'll try to finish the queues this week (I started this weekend),
and I'll try to do my first checkin in CVS next week (with the proper
generic/specific headers...).

Don't worry about using threads in the server and making tons of
Linux-specific assumptions, as the TCP/IP module is OS-specific. I'll start
merging the IPC and TCP/IP code as soon as I receive some code.

if you guys need a tcp/ip "library" that simplifies the use of sockets that
i have or need a hand to program that part just tell me.

[ANet-devel] Short-Term Roadmap

[Benoit N. <be...@ma...>]

Here's a *VERY* short-term list of what we should do:

1. Clients <---> Deamon <--TCP/IP--> Deamon <---> Clients
   I should be able to finish that next week.
2. Same thing, but with queues, with separated generic/specific code,
   and the first checkin in CVS. This should be done at the middle
   of february.
3. Deamon can connect to multiple deamons on TCP/IP, some basic queries.
   This should be done at the end of March.

Chris (Christopher Jensen) is finishing some TCP/IP code, and I'm already
implementing some queues. I may need some help from ajaya to put both IPC
and TCP/IP together.

We will need a lot of "testing" for the CVS account in SourceForge. I'll
try to tie a mailing list (anet-checkins) to CVS so that we'll get an email
each time someone checkins something.

I'll try to help to have something at Gnutella-level by the end of march on
Linux, but you'll have to help too, since I'll spend a bit more time on
docs and the web site. Quentin, you'll have to help me a bit for the HTML,
CSS, Perl...

Basically, don't do too much code before we have some properly organized
code and header files. If it's OK with everyone, I'll do that myself.

I'll completely rewrite that "task manager" thing in SourceForge to reflect
the current state of the project. I'll try to assign you some tasks, but
I'm not forcing you to do something you don't want to do. Tell me if a task
I assigned to you is a problem.

Oh, and for those I haven't heard from almost one month or so (Jonathan
Mitchell, Dale Thatcher and Kumaran Nagaram Srimantharaja), show some sign
of life, or, sorry, I'll have to remove you from the project...

[ANet-devel] TimeToLive security hole

[Benoit N. <be...@ma...>]

Here's a question Mathieu sent me two weeks ago, and what I replied. Note
that his question raises an important security hole that currently exist in
Gnutella and that might be a problem for us.
