Also has a limited support for webdav. .BR This manual page documents \fBWeborf\fP's command-line parameters. .BR \fBWeborf\fP is released under the GNU General Public License version 3. .SH OPTIONS .SS .SS Options: .TP .B \-b, \-\-basedir Must be followed by a valid directory. Weborf will use this directory as root directory, and won't send files located in parent dirs. But it is still possible for server\-side scripts to read contents located anywhere on the filesystem. Links are also a workaround to exit from the base directory. Defaults to /srv/www. .TP .B \-a, \-\-auth Must be followed by a unix socket listened by a program who will handle authentication. See the website for more details. .TP .B \-c, \-\-cgi Must be followed by a list (separated with commas and without spaces) of CGI formats and the binary to execute that format. For example: .php,/usr/bin/php-cgi,.sh,/usr/bin/sh-cgi In /etc/weborf.conf there is a 'cgi' directive, corresponding to this option. It is used when launching weborf as SystemV daemon. .TP .B \-C, \-\-cache Must be followed by a directory that will be used to store cached files. To flush the cache (empty that directory) you must delete the files in the directory. .TP .B \-T, \-\-inetd Must be specified when using weborf with inetd or xinetd. It will be still necessary to specify the used port, to pass the correct value to the CGI scripts. The \-u directive will be ignored. Daemon \-d mode should not be used. .TP .B \-t, \-\-tar If used, instead of sending directory listing when requesting a directory, weborf will send a tar.gz file with the content of that directory. It is used mainly to share files and preserving their permissions. It cannot be used together with https. .TP .B \-Y, \-\-yesexec When used, weborf will enable CGI. .TP .B \-m, \-\-mime When used, weborf will send the Content-Type header. It is strongly advised to use it when using weborf as production server because some browsers rely on this field. This value will not affect the CGI pages. .TP .B \-i, \-\-ip Must be followed by a valid IP address (v6 or v4, depending on how weborf was compiled. Run weborf \-h to know it), and weborf will accept only connections directed to that specific IP. If the IP address provided isn't used by a network device on the host, weborf will terminate. By default weborf listens to all IP addresses on the local host. .TP .B \-k, \-\-caps Shows some compile-time options in a machine-readable format. .TP .B \-p, \-\-port Must be followed by a valid port number (between 1 and 65535), and weborf will listen to incoming connection on the specified port. If the port is already used weborf will terminate. To use low port numbers (less than 1024) it is necessary to execute the process as root. Thus it isn't a good idea to run a webserver with root privileges, so it is possible to specify another user. .TP .B \-S, \-\-cert Path to the SSL certificate. Enables https. Requires a key to be passed as well. .TP .B \-K, \-\-key Path to the SSL key. Enables https. Requires a certificate to be passed as well. .TP .B \-V, \-\-virtual Enables weborf to use virtualhosts. The basedir supplied with \-b will be the default one (will be used if the requested host is unknown). Every virtualhost must be in the form host[:port]=basedir. The port must be specified if the port used is different than 80. And the basedir must end with a /. To separate many virtualhosts, use a comma, and avoid spaces. To make weborf use different virtualhosts on different ports, it will be necessary to launch many weborf's processes. This can now be achieved easily by creating multiple configuration files and using the systemd units like weborf@cfgfile.conf .TP .B \-I, \-\-index Must be followed by a list (separated with commas and without spaces) of index files. Weborf will try to load an index file following the order they're listed, and if none is found it will list the content of the directory. In /etc/weborf.conf there is an 'indexes' directive, corresponding to this option. It is used when launching weborf as SystemV daemon. .TP .B \-u, \-\-uid Must be followed by a valid uid, different from 0. Weborf will use this user to do his work, but will bind to the network port with the previous user. This mechanism is meant to let users execute it as root and use port 80, and then let it run without root privileges. .TP .B \-g, \-\-gid Must be followed by a valid gid, different from 0. Weborf will use this user to do his work, but will bind to the network port before changing. .TP .B \-d Runs weborf as a daemon. It will not terminate when its father process terminates, and it will leave the shell free to receive commands. .SS .SH SCRIPTING Weborf is able to send dynamically generated pages using php-cgi (if installed). When a filename ends with ".php", weborf will use php to execute this file before sending it to the client. The \-c switch will override the default behavior. .BR It is also possible to create scripts or binaries in other languages, just read rfc3875 to know how to handle parameters. .SH RETURN VALUE .TP .B 0 Normal termination occurred after a signal, a daemonization or a print version and exit or so on... .TP .B 1 Basedir is not a directory .TP .B 2 Invalid IP address .TP .B 3 Port already in use .TP .B 4 Invalid port number .TP .B 5 Authentication socket doesn't exist or is not a unix socket .TP .B 6 Too many indexes provided as parameter to \-I or to \-c. Increasing MAXINDEXCOUNT in the file options.h and recompiling can solve the problem. But providing a reasonable amount of index file names would be a better solution. .TP .B 7 Unable to allocate memory .TP .B 9 Unable to change UID .TP .B 10 Error with cache directory .TP .B 19 Invalid parameters on command line .SS .SH "SIGNALS" .TP .B SIGUSR1 Prints the internal status of the socket's queue and threads on the standard output .SS .SH "SEE ALSO" .BR weborf.conf(5), php (1) .SH VERSION .BR Weborf 0.13 .SH WEB .BR https://ltworf.github.io/weborf/ .SH AUTHORS .nf Salvo "LtWorf" Tomaselli Salvo Rinaldi .br weborf-1.0/listener.h0000644000175000017500000000203214515255520011556 00000000000000/* Weborf Copyright (C) 2007 Salvo "LtWorf" Tomaselli Weborf is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

Also has a limited support for webdav. .br Can be started as stand-alone or as system daemon. This manual page documents Weborf's configuration file, used only when it is started as daemon. .br .SH DESCRIPTION Options are case sensitive. Immediately followed by the equal = sign, without any space between name and value. Lines beginning with # will be ignored and treated as comments. .P When systemd is in use, every .conf file in /etc/weborf.d/ is used to start a different instance of weborf, with a different configuration. Otherwise the file /etc/weborf.conf is used to start a single instance of weborf. .SS .TP .B indexes By default weborf searches for index.html. Anyway it is possible to specify a different index file and also many index files. Name of the pages must be separated by a comma and between them there aren't spaces. .TP .B basedir Default base directory used by the webserver. The default means that this will be used also when virtual hosts are enabled, if the requested host is unknown. Of course the user used for the webserver will need to have access to this directory. .TP .B use-cgi Can be true or false. If false weborf will handle all files as normal files. Otherwise it will use the CGI protocol to execute some files. Defaults to false. .TP .B use-mime Can be true or false. If true weborf will send the Content-Type header to the clients. Turning it off will increase speed but might cause problems with some old clients. .TP .B cgi List of extensions to consider as dynamic pages and binaries to execute them. It takes a file format and a path, comma separated, and the list can include more formats and paths. Eg: cgi=.php,/bin/phpexecutor,.sh,/bin/shellexecutor .TP .B auth-socket Path of the unix socket that weborf will use to connect to the authentication server. When this is enabled, for every HTTP request weborf opens a connection to this socket, forwards the request, and the authentication daemon is in charge of deciding whether to accept or deny the request. Examples are provided in /usr/share/doc/weborf/examples. .TP .B cachedir Will set the path of the directory used for caching. When this is enabled, weborf will cache PROPFIND and directory listing requests, making them faster. .TP .B user Username of the user that will run the webserver. On Debian this is usually www-data. .TP .B group Groupname of the group that will run the webserver. On Debian this is usually www-data. .TP .B port The port to use. .TP .B key Absolute path to the SSL key file. It must be used with the cert option. .br When set, weborf will use HTTPS instead of HTTP. .TP .B cert Absolute path to the SSL certificate file. It must be used with the key option. .br When set, weborf will use HTTPS instead of HTTP. .TP .B virtual This directive is used to enable virtualhosts. The format is: virtual=localhost=/var/www/,serverq.com=/var/www-alt/ .br To run on multiple ports, more instances are needed. .TP .B start If this is set to auto, when systemd is in use, the instance using this configuration file is considered as part of the weborf service and started/stopped along with it. It does nothing with other init systems. .SS .SH "SEE ALSO" .BR weborf (1) .SH WEB .BR https://ltworf.github.io/weborf/ .SH AUTHORS .nf Salvo "LtWorf" Tomaselli Salvo Rinaldi .br weborf-1.0/myio.h0000644000175000017500000000311214515255520010706 00000000000000/* Weborf Copyright (C) 2010-2018 Salvo "LtWorf" Tomaselli Weborf is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.

qweborf qweborf qweborf Shares files using the HTTP protocol condivide file usando il protocollo HTTP

Qweborf provides an easy to use graphical interface to share local files using the HTTP protocol.

It can enable writing on the server, webdav, authentication and sending directories as tar.gz.

It can try to work across NAT.

Qweborf fornisce un'interfaccia grafica facile da usare per condividere file locali usando il protocollo HTTP.

Può abilitare la scrittura sul server, WebDAV, l'autenticazione e l'invio di directory come tar.gz.

Può provare a funzionare attraverso NAT.
