howto compile and install this package
|
||||||
|
======================================
|
||||||
|
|
||||||
|
|
||||||
|
really short install instructions
|
||||||
|
---------------------------------
|
||||||
|
|
||||||
|
$ make
|
||||||
|
$ su -c "make install"
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
the more detailed version
|
||||||
|
-------------------------
|
||||||
|
|
||||||
|
Make sure you use GNU make. The file name "GNUmakefile" isn't a joke,
|
||||||
|
this package really requires GNU make.
|
||||||
|
|
||||||
|
As first step make will do some config checks on your system and write
|
||||||
|
the results to Make.config. If you want to have a look at Make.config
|
||||||
|
before the actual build starts you can run this step separately using
|
||||||
|
"make config".
|
||||||
|
|
||||||
|
The Makefiles use the usual GNU-ish Makefile conventions for variable
|
||||||
|
names and default values, i.e. prefix=/usr/local, ...
|
||||||
|
|
||||||
|
The values for some frequently adapted variables are initialized from
|
||||||
|
the enviroment. Thus you can change the defaults simply by setting
|
||||||
|
environment variables:
|
||||||
|
|
||||||
|
$ prefix="/usr"
|
||||||
|
$ CFLAGS="-O3 -mcpu=i686"
|
||||||
|
$ export prefix CFLAGS
|
||||||
|
|
||||||
|
Almost any variable can be overridden on the make command line. It is
|
||||||
|
often used this way to install into some buildroot for packaging ...
|
||||||
|
|
||||||
|
$ su -c "make DESTDIR=/tmp/buildroot install"
|
||||||
|
|
||||||
|
... but it works for most other variables equally well. There are
|
||||||
|
some exceptions through, it usually does _not_ work for CFLAGS for
|
||||||
|
example.
|
||||||
|
|
||||||
|
Try "make verbose=yes" if you want to see the complete command lines
|
||||||
|
executed by make instead of the short messages (for trouble shooting,
|
||||||
|
because you like this way, for whatever reason ...). This also makes
|
||||||
|
the config checks performed by "make config" more verbose.
|
||||||
|
|
||||||
|
If you don't trust my Makefiles you can run "make -n install" to see
|
||||||
|
what "make install" would do on your system. It will produce
|
||||||
|
human-readable output (unlike automake ...).
|
||||||
|
|
||||||
|
Have fun,
|
||||||

This is a simple http server for pure static content. You
|
||||||
|
can use it to serve the content of a ftp server via http for
|
||||||
|
example. It is also nice to export some files the quick way
|
||||||
|
by starting a http server in a few seconds, without editing
|
||||||
|
some config file first.
|
||||||
|
|
||||||
|
It uses sendfile() and knows how to use sendfile on linux and FreeBSD.
|
||||||
|
Adding other systems shouldn't be difficult. To use it with linux
|
||||||
|
you'll need a 2.2.x kernel and glibc 2.1.
|
||||||
|
|
||||||
|
There is some sendfile emulation code which uses a userland bounce
|
||||||
|
buffer, this allows to compile and use webfs on systems without
|
||||||
|
sendfile().
|
||||||
|
|
||||||
|
|
||||||
|
Features/Design:
|
||||||
|
================
|
||||||
|
|
||||||
|
* single process: select() + non-blocking I/O.
|
||||||
|
* trimmed to use as few system calls as possible per request.
|
||||||
|
* use sendfile to avoid copying data to userspace.
|
||||||
|
* optional thread support. Every thread has its own select
|
||||||
|
loop then (compile time option, off by default, edit the
|
||||||
|
Makefile to turn it on).
|
||||||
|
* automatically generates directory listings when asked for a
|
||||||
|
directory (check for index.html available as option), caches
|
||||||
|
the listings.
|
||||||
|
* no config file, just a few switches. Try "webfsd -h" for a
|
||||||
|
list, check the man page for a more indepth description.
|
||||||
|
* Uses /etc/mime.types to map file extentions to mime/types.
|
||||||
|
* Uses normal unix access rights, it will deliver every regular
|
||||||
|
file it is able to open for reading. If you want it to serve
|
||||||
|
public-readable files only, make sure it runs as nobody/nogroup.
|
||||||
|
* supports keep-alive and pipelined requests.
|
||||||
|
* serves byte ranges.
|
||||||
|
* supports virtual hosts.
|
||||||
|
* supports ipv6.
|
||||||
|
* optional logging in common log file format.
|
||||||
|
* optional error logging (to syslog / stderr).
|
||||||
|
* limited CGI support (GET requests only).
|
||||||
|
* optional SSL support.
|
||||||
|
|
||||||
|
|
||||||
|
Plans/BUGS/TODO
|
||||||
|
===============
|
||||||
|
|
||||||
|
* figure out why the acroread plugin doesn't like my
|
||||||
|
multipart/byteranges responses.
|
||||||
|
* benchmarking / profiling.
|
||||||
|
|
||||||
|
Don't expect much more features. I want to keep it small and
|
||||||
|
simple. It is supported to serve just files and to do this in a good
|
||||||
|
and fast way. It is supposed to be HTTP/1.1 (RfC 2068) compliant.
|
||||||
|
Conditional compliant as there is no entity tag support.
|
||||||
|
|
||||||
|
|
||||||
|
Compile/Install
|
||||||
|
===============
|
||||||
|
|
||||||
|
$ make
|
||||||
|
$ su -c "make install"
|
||||||
|
|
||||||
|
See INSTALL for more details.
|
||||||
|
|
||||||
|
|
||||||
|
Tuning
|
||||||
|
======
|
||||||
|
|
||||||
|
The default for the number of parallel connections is very low (32),
|
||||||
|
you might have to raise this.
|
||||||
|
|
||||||
|
You probably don't get better performance by turning on threads. For
|
||||||
|
static content I/O bandwidth is the bottleneck. My box easily fills
|
||||||
|
up the network bandwidth while webfsd uses less than 10% CPU time
|
||||||
|
(Pentium III/450 MHz, Fast Ethernet, Tulip card).
|
||||||
|
|
||||||
|
You might win with threads if you have a very fast network connection
|
||||||
|
and a lot of traffic. The sendfile() system call blocks if it has to
|
||||||
|
read from harddisk. While one thread waits for data in sendfile(),
|
||||||
|
another can keep the network card busy. You'll probably get best
|
||||||
|
results with a small number of threads (2-3) per CPU.
|
||||||
|
|
||||||
|
Enough RAM probably also helps to speed up things. Although webfs
|
||||||
|
itself will not need very much memory, your kernel will happily use
|
||||||
|
the memory as cache for the data sent out via sendfile().
|
||||||
|
|
||||||
|
I have no benchmark numbers for webfsd.
|
||||||
|
|
||||||
|
|
||||||
|
Security
|
||||||
|
========
|
||||||
|
|
||||||
|
I can't guarantee that there are no security flaws. If you find one,
|
||||||
|
report it as a bug. I've done my very best while writing webfsd, I hope
|
||||||
|
there are no serious bugs like buffer overflows (and no other bugs of
|
||||||
|
course...). If webfsd dumps core, you /have/ a problem; this really
|
||||||
|
shouldn't happen.
|
||||||
|
|
||||||
|
Don't use versions below 1.20, there are known security holes.
|
||||||
|
|
||||||
|
|
||||||
|
Changes in 1.21
|
||||||
|
===============
|
||||||
|
|
||||||
|
* large file support.
|
||||||
|
* s/sprintf/snprintf/ in some places.
|
||||||
|
* changed timestamp handling, webfs doesn't attempt to parse them
|
||||||
|
any more but does a strcmp of rfc1123 dates.
|
||||||
|
* access log uses local time not GMT now.
|
||||||
|
* some ssl/cgi cleanups (based on patches from Ludo Stellingwerff).
|
||||||
|
* misc fixes.
|
||||||
|
|
||||||
|
|
||||||
|
Changes in 1.20
|
||||||
|
===============
|
||||||
|
|
||||||
|
* CGI pipe setup bugfix.
|
||||||
|
* Don't allow ".." as hostname (security hole with vhosts enabled).
|
||||||
|
* fix buffer overflow in ls.c with very long file names.
|
||||||
|
* misc other fixes / cleanups.
|
||||||
|
|
||||||
|
|
||||||
|
Changes in 1.19
|
||||||
|
===============

|
||||||
|
(pointed out by Jedi/Sector One <j@pureftpd.org>).
|
||||||
|
* Makefile changes.
|
||||||

|
||||||
|
|
||||||
|
|
||||||
|

|
||||||
|
Ludo Stellingwerff <ludo@jonkers.nl>).
|
||||||
|
* run only the absolute needed code with root privileges
|
||||||
|
(bind+chroot) if installed suid-root.
|
||||||
|
* Makefile tweaks.
|
||||||
|
* fixed buffer overflow in request.c
|
||||||
|
* started user home-directory support.
|
||||||

|
||||||
|
|
||||||
|

||||||
|
===============
|
||||||
|
|
||||||
|
* fix bug in request cleanup code (didn't cleanup properly after
|
||||||
|
byte-range requests, thus making webfsd bomb out on non-range
|
||||||
|
requests following a byte-range request on the same keep-alive
|
||||||
|
connection).
|
||||||
|
|
||||||
|
|
||||||
|
Changes in 1.16
|
||||||
|
===============
|

||||||
|
|
||||||
|
Changes in 1.6
|
||||||
|
==============
|

|
||||||
|
==============
|
||||||
|
|
||||||
|
* fixed the sloppy usage of addrlen for the ipv6 name lookup
|

* allow to write the access log to stdout (use "-" as filename)
|
||||||
|

||||||
|
user/passwd combinations)
|
||||||
|
* added virtual host support.
|
||||||
|
* webfsd can chroot to $DOCUMENT_ROOT now.

|
||||||
|
|
||||||
|
Changes in 1.3
|
||||||
|

|
(doesn't show up in ps anymore)
|
||||||
|
|
||||||
|
|
||||||
|
Changes in 1.2

|
||||||
|
|
||||||
|
Changes in 1.1
|
||||||
|
==============

||||||
|
|
||||||
|
* added basic authentication (one username/password for all files)
|
||||||
|
|
||||||
|
|
||||||
|
Changes in 1.0
|
||||||
|
==============
|
||||||
|
|
||||||
|
* added some casts to compile cleanly on Solaris.
|
||||||
|
* new -F flag (don't run as daemon).
|
||||||
|
|
||||||
|
|
||||||
|
Changes in 0.9
|
||||||
|
==============
|
||||||
|
|

||||||
|
|
||||||
|
* fixed a bug in the directory cache.
|
||||||
|
* fixed uncatched malloc()/realloc() failures.
|
||||||
|
* added optional pthreads support. Edit the Makefile to turn
|
||||||
|
it on.
|
||||||
|
|
||||||
|
|
||||||
|
Changes in 0.7
|
||||||
|
==============
|
||||||
|
|
||||||
|
* some portability problems fixed (0.6 didn't compile on FreeBSD).
|
||||||
|
* added a sendfile() emulation based on read()/write() as fallback
|
||||||
|
if there is no sendfile() available.
|
||||||
|
* bugfix: '#' must be quoted too...
|
||||||
|
|
||||||
|
|
||||||
|
Changes in 0.6
|
||||||
|
==============
|
||||||
|
|
||||||

|
||||||
|
* new switch to specify the location of the mime.types file.
|
||||||
|
* byte range bug fixes.
|
||||||
|
* switch for the hostname has been changed ('-s' => '-n').
|
||||||
|
* optional log errors to the syslog (switch '-s').
|
||||||
|
* added sample start/stop script for RedHat.
|
||||||
|
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
|
||||||
|
Changes in 0.4
|
||||||
|
==============
|
||||||
|
|
||||||
|
* last-modified headers (and 304 responses) for directory listings.
|
||||||
|
* new switch: -f index.html (or whatever you want to use for
|
||||||
|
directory indices)
|
||||||
|
* killed the access() system calls in the ls() function.
|
||||||
|
* added cache for user/group names.
|
||||||
|
* wrote a manual page.
|
||||||
|
|
||||||
|
|
||||||
|
Changes in 0.3
|
||||||
|
==============
|
||||||
|
|
||||||
|
* multipart/byteranges improved: You'll get a correct Content-length:
|
||||||
|
header for the whole thing, and we can handle keep-alive on these
|
||||||
|
requests now.
|
||||||
|
* bugfix: catch accept() failures.
|
||||||
|
* bugfix: quote the path in 302 redirect responses.
|
||||||
|
* accept absolute URLs ("GET http://host/path HTTP/1.1")
|
||||||
|
* fixed handling of conditional GET requests (hope it is RFC-Compilant
|
||||||
|
now...).
|
||||||
|
* bugfix: '+' must be quoted using %xx.
|
||||||
|
|
||||||
|
|
||||||
|
Changes in 0.2
|
||||||
|
==============
|
||||||
|
|
||||||
|
* added URL quoting.
|
||||||
|
* root can set uid/gid now.
|
||||||
|
* webfs ditches any setuid/setgid priviliges after binding to the
|
||||||
|
TCP port by setting effective to real uid/gid. It should be safe
|
||||||
|
to install webfsd suid root to allow users to use ports below
|
||||||
|
1024 (and _only_ this of course). If anyone finds a flaw in this
|
||||||
|
code drop me a note.
|
||||||
|
* more verbose directory listing.
|
||||||
|
* added logging. It does the usual logfile reopen on SIGHUP.
|
||||||
|
|
||||||
|
|
||||||
|
Changes in 0.1
|
||||||
|
==============
|
||||||
|
|
||||||
|
* first public release.
|
||||||
|
|
||||||
|
|
||||||
|
Have fun,
|

|
||||||
|
.SH NAME
|
||||||
|
webfsd - a lightweight http server
|
||||||
|
.SH SYNOPSIS
|
||||||
|
.B webfsd [ options ]
|
||||||
|
.SH DESCRIPTION
|
||||||
|
This is a simple http server for purely static content. You
|
||||||
|
can use it to serve the content of a ftp server via http for
|
||||||
|
example. It is also nice to export some files the quick way
|
||||||
|
by starting a http server in a few seconds, without editing
|
||||||
|
some config file first.
|
||||||
|
.SH OPTIONS
|
||||||
|
.TP
|
||||||
|
.B -h
|
||||||
|
Print a short \fBh\fPelp text and the default values for all options.
|
||||||
|
.TP
|
||||||
|
.B -4
|
||||||
|
Use IPv\fB4\fP.
|
||||||
|
.TP
|
||||||
|
.B -6
|
||||||
|
Use IPv\fB6\fP.
|
||||||
|
.TP
|
||||||
|
.B -d
|
||||||
|
Enable \fBd\fPebug output.
|
||||||
|
.TP
|
||||||
|
.B -s
|
||||||
|
Write a start/stop notice and serious errors to the \fBs\fPyslog.
|
||||||
|
Specify this option twice to get a verbose log (additional log
|
||||||
|
events like dropped connections).
|
||||||
|
.TP
|
||||||
|
.B -t sec
|
||||||
|
Set network \fBt\fPimeout to >sec< seconds.
|
||||||
|
.TP
|
||||||
|
.B -c n
|
||||||
|
Set the number of allowed parallel \fBc\fPonnections to >n<. This is
|
||||||
|
a per-thread limit.
|
||||||
|
.TP
|
||||||
|
.B -a n
|
||||||
|
Configure the size of the directory cache. Webfs has a
|
||||||
|
cache for directory listings. The directory will be
|
||||||
|
reread if the cached copy is more than one hour old or if
|
||||||
|
the mtime of the directory has changed. The mtime will be
|
||||||
|
updated if a file is created or deleted. It will \fBnot\fP
|
||||||
|
be updated if a file is only modified, so you might get
|
||||||
|
outdated time stamps and file sizes.
|
||||||
|
.TP
|
||||||
|
.B -j
|
||||||
|
Do not generate a directory listing if the index-file isn't found.
|
||||||
|
.TP
|
||||||
|
.B -y n
|
||||||
|
Set the number of threads to spawn (if compiled with thread support).
|
||||||
|
.TP
|
||||||
|
.B -p port
|
||||||
|
Listen on \fBp\fPort >port< for incoming connections.
|
||||||
|
.TP
|
||||||
|
.B -r dir
|
||||||
|
Set document \fBr\fPoot to >dir<.
|
||||||
|
.TP
|
||||||
|
.B -R dir
|
||||||
|
Set document root to >dir< and chroot to >dir< before start
|
||||||
|
serving files. Note that this affects the path for the access log
|
||||||
|
file and pidfile too.
|
||||||
|
.TP
|
||||||
|
.B -f file
|
||||||
|
Use >file< as index \fBf\fPile for directories. If a client
|
||||||
|
asks for a directory, it will get >file< as response if such
|
||||||
|
a file exists in the directory and a directory listing otherwise.
|
||||||
|
index.html is a frequently used filename.
|
||||||
|
.TP
|
||||||
|
.B -n hostname
|
||||||
|
Set the host\fBn\fPame which the server should use (required
|
||||||
|
for redirects).
|
||||||
|
.TP
|
||||||
|
.B -i ip
|
||||||
|
Bind to \fBI\fPP-address >ip<.
|
||||||
|
.TP
|
||||||
|
.B -l log
|
||||||
|
\fBL\fPog all requests to the logfile >log< (common log format).
|
||||||
|
Using "-" as filename makes webfsd print the access log to stdout,
|
||||||
|
which is only useful together with the -F switch (see below).
|
||||||
|
.TP
|
||||||
|
.B -L log
|
||||||
|
Same as above, but additional flush every line. Useful if you
|
||||||
|
want monitor the logfile with tail -f.
|
||||||
|
.TP
|
||||||
|
.B -m file
|
||||||
|
Read \fBm\fPime types from >file<. Default is /etc/mime.types.
|
||||||
|
The mime types are read before chroot() is called (when started
|
||||||
|
with -R).
|
||||||
|
.TP
|
||||||
|
.B -k file
|
||||||
|
Use >file< as pidfile.
|
||||||
|
.TP
|
||||||
|
.B -u user
|
||||||
|
Set \fBu\fPid to >user< (after binding to the tcp port). This
|
||||||
|
option is allowed for root only.
|
||||||
|
.TP
|
||||||
|
.B -g group
|
||||||
|
Set \fBg\fPid to >group< (after binding to the tcp port). This
|
||||||
|
option is allowed for root only.
|
||||||
|
.TP
|
||||||
|
.B -F
|
||||||
|
Don't run as daemon. Webfsd will not fork into background, not detach
|
||||||
|
from terminal and report errors to stderr.
|
||||||
|
.TP
|
||||||
|
.B -b user:pass
|
||||||
|
Set user+password for the exported files. Only a single
|
||||||
|
username/password combination for all files is supported.
|
||||||
|
.TP
|
||||||
|
.B -e sec
|
||||||
|
\fBE\fPxpire documents after >sec< seconds. You can use that to
|
||||||
|
make sure the clients receive fresh data if the content within your
|
||||||
|
document root is updated in regular intervals. Webfsd will send
|
||||||
|
a Expires: header set to last-modified time plus >sec< seconds, so
|
||||||
|
you can simply use the update interval for >sec<.
|
||||||
|
.TP
|
||||||
|
.B -v
|
||||||
|
Enable \fBv\fPirtual hosts. This has the effect that webfsd expects
|
||||||
|
directories with the hostnames (lowercase) under document root. If
|
||||||
|
started this way: "webfsd -v -r /home/web", it will look for the file
|
||||||
|
/home/web/ftp.foobar.org/path/file when asked for
|
||||||
|
http://ftp.FOObar.org:8000/path/file.
|
||||||
|
.TP
|
||||||
|
.B -x path
|
||||||
|
Use >path< as CGI directory. >path< is interpreted relative to the
|
||||||
|
document root. Note that CGI support is limited to GET requests.
|
||||||
|
.TP
|
||||||
|
.B -S
|
||||||
|
\fBS\fPecure web server mode. Warning: This mode is strictly for https.
|
||||||
|
.TP
|
||||||
|
.B -C
|
||||||
|
File to use as SSL \fBc\fPertificate. This file must be in chained PEM
|
||||||
|
format, first the privat RSA key, followed by the certificate.
|
||||||
|
.TP
|
||||||
|
.B -P
|
||||||
|
\fBP\fPassword for accessing the SSL certificate.
|
||||||
|
.P
|
||||||
|
Webfsd can be installed suid root (although the default install
|
||||||
|
isn't suid root). This allows users to start webfsd chroot()ed
|
||||||
|
and to bind to ports below 1024. Webfsd will drop root privileges
|
||||||
|
before it starts serving files.
|
||||||
|
.P
|
||||||
|
Access control simply relies on Unix file permissions. Webfsd will
|
||||||
|
serve any regular file and provide listings for any directory it is
|
||||||
|
able to open(2).
