you are using b25 built with SCons?

Hi,
I'm trying to cross-compile fsp for a MPC5200 powerpc architecture but can't get the configure
script to crank out an adequate makefile. Has anyone gone through this before ??

After more than 4 years there is new release of FSP:

Version 2.8.1b25 - 10 Sep 2009
        GNU autotools build system was entirely replaced by SCons
        corrected misleading comment in client/lib.c
        default packetsize changed to do best fit into maximum 1500 mtu
          Ethernet frame = 1460. This is needed for speedup the booting of
          Etherboot clients
        PROTOCOL: when computing checksum declare *t as unsigned char * type
        changed typo setguid -> setgid in fspd.conf
        fspd.conf: added note that only numeric uid values works
        fspd.conf: added more information about packetsize
        fspd.1: updated information about packetsize
        fspd.conf: repaired some spelling errors by ispell
        MTU changed from 1500 to 1492 for better operation on pppOE networks
        Max payload changed from 4096 to 4380 bytes (3 packets)
        fspd: command line argument now overrides config file
        updated year in copyright
        fsetup command added to setup.sh
        fsetup command added to setup.csh
        fcd: remove trailing \r\n from readme file
        fcd: do not print empty line after directory protection
        fsetupcmd: don't crash if called with numeric address
        fspscan: commited fix by Yang Hong
        SCONS: turning on maintainer-mode links against efence (if possible)
          same thing like ./configure do
        unbreak compilation on systems without large files
        cygwin support disabled. we cant detect it from SCons yet
        frmdir works now. It didnt worked due to adding new access rights
          DIR_NOLIST and DIR_NOGET
        MACHINES updated. Builds confirmed on Ubuntu 8.04.3,
          FreeBSD 6.4 and FreeBSD 7.2
        fsetupcmd added to fspmerge client
        SCons can now build SGML FSP FAQ if sgmlfmt is found during build
          process
        fspmerge now prints short help text if it is invoked as fspmerge
        FILES is up to date now

https://sourceforge.net/projects/fsp/files/fsp/2.8.1b25/fsp-2.8.1b25.tar.gz/download

Compile tested on FreeBSD and Ubuntu Linux.

I installed mantis BT instead of using sf.net bug tracker. I wanted 
Trac, but Trac doesnt come with bzr plugin and you cant install custom 
plugins into trac.

https://sourceforge.net/apps/mantisbt/fsp/

No code changes, just fixed to SCons build framework.
Framework modularised.
Can import CFLAGS from env. variable or from CCFLAGS or CFLAGS command  
line option.

This is build system bugfix release. No code changes. Static library name  
changed to libfsplib.a so other programs can find it in their ./configure  
scripts.

Changelog

         optionally build and install shared library (EXPERIMENTAL FEATURE)
           based on report by Ahmed El-Mahmoudy, Debian fsplib maintainer
         name of static fsp library should be libfsplib.a as it used to be
           in libtool's days. Noticed by Ahmed El-Mahmoudy.

I migrated CVS repository for all fsp.sf.net subprojects to bazaar repo.  
Bazaar have more features over CVS, easier to use, atomic commits, more  
robust repository and good offline support. Because it is distributed VCS  
i can now have easy way to do backups of VCS repo without need to use  
rsync.

links on fsp.sf.net should be updated to new location. If they are not,  
report it as error.

no. no paying customer is interested in ipv6.

Interesting. Does/will it support IPv6? I haven't been able to test
IPv6 support in my code because no server supports it currently.

Same as perl, which is dual licensed to artistic and GPL. Artistic is
somewhat LGPL-like (you have to share modifications to the library,
but can freely use it in closed source programs).

It checks file timestamps, but currently doesn't support resuming transfers.

3 years in FSP is nothing, i am testing next version of fspd for about same time.

what kind of license it is? BSD or GPL? We have also Python FSP stack not bad software, but it is GPL, so i am not interested in it.

> I've put two script using it at http://www.xs4all.nl/~silemia/fsp/,
mirror script supports resume and checks file timestamps local vs remote? I dont know perl

Hi all,

I recently found back an old piece of code of mine. I finished it and
uploaded it to CPAN (you can find it at
http://search.cpan.org/~leont/Net-FSP/). It's three years later than
expected, but it's finally here: a Perl FSP implementation.

It was kind of interesting to write the code, as I had never
implemented a binary protocol before. It turned out to be easier than
expected. Having said that, I haven't been able to do much testing, so
don't be too surprised if something breaks at this stage.

I've put two script using it at http://www.xs4all.nl/~silemia/fsp/,
fspclient and mirror. I think it should be pretty obvious what each of
them does. fspclient has a help command that should get you all
started. I saw a mirroring tool was on the task list so I picked that
one up too. It gives a pretty good idea of how it is to work with
Net::FSP. Both scripts accept the same environmental variables as the
official FSP suite, so you won't have to change too much to start
using them.

Regards,

Leon Timmermans

i dont have bazaar repo for free FSP, so CVS on sf.net contains latest patches to that branch.

use CVS version for latest patches, i dont have currently access to computer which hosts latest FSP bazaar-ng repo so i cant test if CVS version carries all patches for non-commercial FSP codebase.

I have to install bazaar repo on sf.net some day, branching in CVS sucks and SVN is not much better, I didnt checked sf.net for years so i dont know if they supports some modern VCS like hg git or bazaar-ng.

Hi,

It's in the FSP server and client code.  I had to mod both.

#ifdef --with-genericproxy or so would be fine.

Once compiled in, I think generic proxy should be available both from the command line and by invocation within the app via a command.  (i.e. you can turn it on either through command line or fsp options menu).

Currently it's set up with the latter... mainly because that's what I got working first.

Thanks,
Thomas

you want to make separate fsp proxy executable or built it into main FSP server code?

I dont want it in server code unless it will be #ifdef and compiled with something like ./configure --with-fsproxy

Hi,

I don't have the original code anymore... it was on zippy.sonoma.edu which has been gone for years.  

The good news is...

I figured out how to add my own cmd to the fsp server [and client] so that I can send data back and forth.  I also added a TCP fetch so that I could shovel data from TCP thru the UDP service and back out to TCP again.  

Put another way... I tunneled a webserver through UDP using FSP.

It seems that it's not that difficult to add the capability legitimately.
I'd like there to be some CLI option to boot it up without the talkative FTP-like i/o so it can operate in straight proxy mode.

The way I want to think about FSP is as a generic proxy server with an FTP-like client as an option... instead of the other way around.

i have nothing against inserting FSP proxy code back to distro. Do you still have original code? I was unable to find it via google about 3 years ago. Its important part of FSP history because i remember it never worked for us!

Hi,

I ran an fsp server and client back in the early 1990s.  The proxy code I remember being around is missing tho'.

Since things have changed and fsp never gained traction for file transfer, would anyone mind if generic proxy functionality gets inserted back into the distro?

Everything functionality that is already there would be preserved, but a switch would be added to allow for port forwarding again.  The delta in code size would not be big.

The nice thing about fsp is that it's never changed much and gotten out of control.  So it's simple and pretty easy to wrap around.  That the C client was built a few years back really helps too.

I would promise to be careful not to bloat the codebase and only restore generic support.  I think a lot of people would like this.

Thanks,
Thomas

Its for some kind of peer to peer app developed using sim toolkit technology,
so it works in any gsm phone. App is kinda cool, sells very well to young
people, because no other GSM provider have something similar to it. Maybe someone copied it now, i but i dont know about it.

> Have you wrote a client for Symbian or other small devices? 
yes i have bunch of FSP libraries coded in ASM for various small devices and
for PIC controllers.

Hello,
I was an "old" user of fsp, from 1994, and I'm very interested in this 
matter, however I used fsp only as alternative file transfer protocol 
between linux boxes. But I still were thinking that, since fsp it is 
quite unused, nobody uses it "seriously". However, now I discover that 
someone uses it intensively, and in a really interesting way. How do you 
use fsp in order to have a "peak" of 350k gsm users?  Since I'm very 
interested, please can you explain better how you use it? Have you wrote 
a client for Symbian or other small devices?
Thank you.

> Itseems that the efficiency of the protocol is not very good.
that's depends how you define efficiency. If you define efficiency as number
of bytes over wire per file size, FSP is good.

> Because the packetsize from server to client is only 1024 bytes
We support larger packets as well, but packet size defaults to 1024. In unreleased beta default packet size is about 1440.

> and the server have to wait for the reply from the client once it send out a message.
Yes, this is important part of FSP design. FSP is designed not to allow more than 1 packet in network between client and server.

> I wonder if there is any improvement to the efficiency of the transfer.
You will get better transfer speed but less reliability with large packet sizes.

> For example, the server might send out several packets and ask for the

This is what windowing transfer protocols like TCP are doing. FSP was designed
to be windowless transfer protocol for various reasons documented on web site.

> This is my thought, I wonder if you have better methods.
What is your goal? Fast file transfer over UDP? Use NFS3 then, but its much
more complicated protocol than FSP.

FSP is very easy to implement transfer protocol for packet networks. With some limitations, it can run over serial lines too.

Primary use of FSP is for: diskless booting, GSM Networks, Trunk networks, Firmware updates etc. Yes, its mainly for embedded systems market. Also some peer to peer network is using it.

FSP scales well, i have about 360k peak GSM clients connected to ONE FSP server running on Solaris 10.

I have read the protocol of FSP and did some experiments
accordingly.Itseems that the efficiency of the protocol is not very
good. Because the
packetsize from server to client is only 1024 bytes and the server have to
wait for the reply from the client once it send out a message. I wonder if
there is any improvement to the efficiency of the transfer. For example, the
server might send out several packets and ask for the confirmation of all of
them from the client. This is my thought, I wonder if you have better
methods. Thanks for your answers.

i cant reproduce fspd crash recorded in bug report 1456395. In my environment,
i run several fspd without crashing for months.

If your fspd crashes, please report it with conf file and OS version. gdb
traceback would be great. you can link fspd against libefence by
scons maintainer-mode=yes
