problems let me know, they'll be sorted out in the next Beta release. At the
point at which people stop complaining the non-beta release will be let out.

FSP Development Battle plan:
============================
* for next 2.8 Stable version (will be called 2.8.2)
2.8.2 - Next Stable version after 10 years or so
- get out this version as soon as possible. 2.8.1b3 and lower are buggy.
- add FSP Rename command
- add FSP Info command
- go out this version as soon as possible. 2.8.1b3 and lower are buggy.
- resolve symlink support problem. This maybe breaks compatibility
with older software versions.
- security: symlink to FILE can escape from FSP root directory.
- fix Sven's Slowaris 8 compile problem
- local bind address FSP_LOCALIP for clients
- bind-ip-address for server
- normalize return error codes of all clients
- server can be run multiple times on the same port, how to check?
on freebsd this works okay. needs re-testing on linux.
- fspd: add special defence against rapid/double fire clients (burst command in fspclient)
* for next point Stable version 2.8.3
- add native symbolic link support
- add FSP change password command
- add FSP command for changing owners
- add FSP command for listing directory owners

-----------------------------------------------------------------------------
This version is fully backwards compatible with 2.7.1 and 2.8.1 both from the
client and the server viewpoints. Bar one thing, the reversed IP problem with
restricted host lists has now been fixed, so if you've deliberately reversed
the IP numbers in that list to get around the bug you should now put them back
in the correct order again.
Another point worth noting is that the next release will go to ANSI-C. If you
have a problem with this then now is the time to let me know. I don't forsee
any portability problems since I would expect that ANSI-C compliant compilers
are available for all platforms by now. This move will aid both maintenance and
any future use of C++ for Application Programming Interfaces.
This version is not quite fully backwards compatible with 2.7.1 and 2.8.1 from
the client and the server viewpoints. See file PROTOCOL for minor changes
in wire-protocol.
If you successfully build this distribution on a machine/OS/compiler
combination which isn't listed in the MACHINES file then please drop me a line

Version - not yet released
Added pidfile.[c|h] from FreeBSD and modified it to fit in (hoaxter)
Added pidfile support, config option is 'pidlogname', the option
is required to start fspd, hope that's ok for most people (hoaxter)
Replaced . file information from INSTALL with a hint to man 1 fspd (hoaxter)
Added pidfile support, config option is 'pidlogname' (hoaxter)
Replaced .file information from INSTALL with a hint to man 1 fspd (hoaxter)
PROTOCOL: Added security section, fixed method of computing of checksums fspd: unlink filecache.c from build
conf: commented dangerours settings for win32 platform which can
cause data loss when fspd.conf is reused on win32 without editing.
Defaults are detected at build time.
fspd: allow to run without pidfile set.
added autogen.sh for regenerating of autoconf on FreeBSD which needs
to set some env. variables unless --enable-maintainer-mode do
not works.
do not free pidfile name on failure
changelog reformated: each entry begins with tab/not spaces.
continuation line has 2 chars leading space
removed trailing spaces from all sources and headers
tests: run random test 2000 times by default
random generator switched to simple2. Better results on both
freebsd and linux systems.
added maximum supported packet size to output of CC_VER command
fspd: -b command line switch for bandwidth limiting
PROTOCOL: Added compatibility section to some commands
Default timeout increased from 180 to 360 seconds.
clients: apply delay timeout also when starting transfer
clients: added env. variable FSP_MAXDELAY for fine-tuning resends
DEFAULT_MAXDELAY added to source code
FSP_TIMEOUT is total number of seconds, not retry count.
clients: try to resend packet on less fatal error (network down or so)
remove clients lock files after sending BYE. code merged from fspclient.
threre is an race condition: After client unlinks lock file and other
clients still runs new client will create new lock file which will
not share secret key with other clients. New client can't communicate
with server until other clients terminates.
man: we did not install fsp_env.7 manpage
allow home directory not starting with /
allow uploads only on file border
up/down speed is in B/s, not b/s.
client tracing improved:
H - not enough bytes for header
C - wrong checksum
S - wrong seq. number
T - truncated
R - First resend
I - Idle resend
client: use random starting seq. number - better for avoiding
seq. number clash with another client
fixed compiler warning on BB_READ4(const char *);
Version 2.8.1b19 - 11 Jan 2004
sven has added fspget URL command to setup.sh.
fixed case for mklargefile.py in tests/Makefile.am
added --enable-debug switch to configure for enabling extra

This is MINIMUM REQUIRED VERSION for applications which are using
javafsp library, only download machine atm. Javafsp library will
be released shortly as separate package.
PROTOCOL updated. Made rules about breaking directory header on
packet boundary more clear. Previous text was from fspd code comment

FSP today
Written by Radim Kolar
FSP uses UDP datagrams and it is reliable even when there is high
number of packet loss. It is usable on WiFi network with 60% packet
loss.
Protocol related
FSP uses UDP datagrams and it is reliable even when there is
high number of packet loss. It is usable on WiFi network with
60% packet loss.
Unlike TCP, FSP has a fast restart when line comes up.
FSP can very quickly addapt to changing line condition. This
is excelent for wireless packet networks. FSP needs about 6
RTT to retune itself after receiving condition goes worse.
And unlike TCP based protocols, FSP has a fast restart when
line improves - It do not needs any RTT; FSP goes immediatly
to maximum possible speed.
Maximum FSP speed is by design lower than maximum speed of TCP
based protocols because it has only 1 packet in the network.
TCP protocol has about 3 packets. Design of FSP protocol
makes impossible to send more than 1 packet into network.
This is nice method for bandwidth protection.
FSP server do not sends any data out unless is asked for. This
solves problem with transfering duplicate data when using
TCP protocol on overloaded lines. About 30% are dupes, thrown
out by client.
FSP server do not sends any data out unless is asked for. This
solves problem with transfering duplicate data when using TCP
protocol on overloaded lines. About 30% are dupes, thrown out
by client. Note: TCP stacks from BSD family has this dupe
ratio much lower.
UDP ports are not often port scanned today. Nobody notice that
you are running a server.
Embedded devices
FSP uses UDP which is unnoticed by many firewalls. FSP server
runs on 21 port by default, if you move it to port 53 (dns)
even strictly configured firewall can be worked around.
FSP protocol is very easy to implement; client core has about
one page of C code. It is ideal for embedded devices for
file-transfer tasks, like firmware downloading. Because of its
simplicity, there is a little chance to writing buggy
implementation.
You want to run anonymous archive and want to keep lamers out.
FSP is also good for remote booting. It is simplier than TFTP
and supports directory listings.
You want to share something without ruining your valueable bandwidth.
FSP protocol can be used as wire-protocol even without using
any layer 2 stuff. It operates in degraded mode with extra
features disabled.
You have overloaded archive site.
You do want to share large data files (movies, ISO images) on
slow (or you do not want to waste valuable bandwidth) lines.
Ideal for sharing files on modem lines.
Internet operation
UDP ports are not often port scanned today, only one exception
is scanning for Windows/Samba file sharing service. Nobody
will notice that you are running a fsp server.

Transport
FSP uses UDP datagrams as transport medium. Minimum UDP packet size (not
including size of UDP, IP and link layer headers) is 12 bytes, maximum UDP
packet size is 1024+12 bytes.
Security
Design
FSP protocol was not designed to transfer secret data. It was designed as
alternative protocol for providing lightweight access to collection of public
files. FSP has the same user level of security as the anonymous FTP file
server. FSP has better network level security, because it was designed
to ressist various denial-of-service attacks. FSP protocol v3 will be
designed to be fully secure. FSP3 will not be backward compatible with
FSP2.
Passwords
Recently, password support was added to protocol, because just
too many people wants it and there were hacked version of FSP with
password support floating around. Passwords are transmited in clear
text over network which makes them a weak protection for determined
intruder.

Due to some unknown reason, method of computing checksums is different in each
