18 Citadel is a sophisticated BBS and groupware package which allows multiple
19 users to simultaneously access the system using a variety of user interfaces.
20 This package (WebCit) is a "middleware" package which presents an HTML/HTTP
21 user interface to the Citadel system.
23 What this means in practice is that after you've installed WebCit, users can
24 access all functions of your system using any web browser. Since this may be
25 the first Citadel experience for many new users, the screens have been designed
26 to be attractive and easy to navigate.
32 Unline some web-based packages, WebCit contains its own standalone HTTP
33 engine. As a result, you can get it running quickly without all that tedious
34 mucking about with Apache configuration files and directories. WebCit is not
35 intended to replace your Apache server, however -- it *only* provides a front
36 end to Citadel. If you do not have another web server running, you may run
37 WebCit on port 80; however, in the more likely situation that you have Apache
38 or some other web server listening on port 80, you must run WebCit on another
39 port. The default is port 2000.
41 To compile from source, enter the usual commands:
42 ./configure --prefix=/usr/local/webcit [or whatever directory you prefer]
46 Then to initialize it:
50 After running setup, you just point your web browser to whatever port you
53 http://your.host.name:2000
57 The included "setup" program is basically just an installation helper that
58 asks a series of questions and then adds the appropriate line to inittab to
59 start WebCit. For most installations, this will do just fine. If you have
60 special circumstances, or if you'd prefer to configure WebCit manually, you
61 may skip the setup program. Instead, open /etc/inittab and add an entry
64 wc:2345:respawn:/usr/local/webcit/webserver
67 Several command-line options are also available. Here's the usage for
68 the "webserver" program:
70 webserver [-i ip_addr] [-p http_port] [-s] [-t tracefile]
71 [-c] [remotehost [remoteport]]
75 webserver [-i ip_addr] [-p http_port] [-s] [-t tracefile]
76 [-c] uds /your/citadel/directory
80 -> ip_addr: the IP address on which you wish your WebCit server to run.
81 You can leave this out, in which case WebCit will listen on all
82 available network interfaces. Normally this will be the case, but if
83 you are running multiple Citadel systems on one host, it can be useful.
85 -> http_port: the TCP port on which you wish your WebCit server to run.
86 This can be any port number at all; there is no standard. Naturally,
87 you'll want to create a link to this port on your system's regular web
88 pages (presumably on an Apache server running on port 80). Or, if you
89 are installing WebCit on a dedicated server, then you might choose to
90 use port 80 after all.
92 -> tracefile: where you want WebCit to log to. This can be a file, a
93 virtual console, or /dev/null to suppress logging altogether.
95 -> The "-c" option causes WebCit to output an extra cookie containing the
96 identity of the WebCit server. The cookie will look like this:
97 Set-cookie: wcserver=your.host.name
98 This is useful if you have a cluster of WebCit servers sitting behind a
99 load balancer, and the load balancer has the ability to use cookies to
100 keep track of which server to send HTTP requests to.
102 -> The "-s" option causes WebCit to present an HTTPS (SSL-encrypted) web
103 service. If you want to do both HTTP and HTTPS, you can simply run two
104 instances of WebCit on two different ports.
106 -> remotehost: the name or IP address of the host on which your Citadel
107 server is running. The default is "localhost".
109 -> remoteport: the port number on which your Citadel server is running.
110 The default is port 504, the IANA-designated standard port for Citadel.
112 -> "uds" is a keyword which tells WebCit that you wish to connect to a
113 Citadel server running on the same computer, rather than using a TCP/IP
114 socket. /your/citadel/directory should be set to the actual name of the
115 directory in which you have Citadel installed
116 (such as /usr/local/citadel). If you run Citadel and WebCit on the same
117 computer, this is recommended, as it will run much faster.
123 WebCit contains a small amount of graphics (buttons, etc.) which are kept
124 in its "static" subdirectory. All site-specific graphics, however, are
125 fetched from the Citadel server.
127 The "images" directory on a Citadel system contains these graphics. The
128 ones which you may be interested in are:
130 -> background.gif: a background texture displayed under all web pages
131 -> hello.gif: your system's logo. It is displayed along with the logon
132 banner, and on the top left corner of each page.
134 If you would like to deploy a "favicon.ico" graphic, please put it in
135 the static/ directory. WebCit will properly serve it from there.
141 WebCit contains support for calendaring and scheduling. In order to use it
142 you must have libical v0.24 (or newer) on your system. You must also be
143 running a Citadel server with calendaring support. The calendar service will
144 be automatically configured and installed if your host system supports it.
146 WebCit also provides Kolab-compatible free/busy data for calendar clients.
147 Unlike the Kolab server, however, there is no need for each user to "publish"
148 free/busy data -- it is generated on-the-fly from the server-side calendar
149 of the user being queried. Note: in order to support Kolab clients, you must
150 have WebCit running in HTTPS mode on port 443, because that is what Kolab
151 clients will be expecting.
154 HTTPS (encryption) SUPPORT
155 --------------------------
157 WebCit now supports HTTPS for encrypted connections. When a secure server
158 port is specified via the "-s" flag, an HTTPS service is enabled.
160 The service will look in the "keys" directory for the following files:
162 citadel.key (your server's private key)
163 citadel.csr (a certificate signing request)
164 citadel.cer (your server's public certificate)
166 If any of these files are not found, WebCit will first attempt to link to the
167 SSL files in the Citadel service's directory (if Citadel is running on the
168 same host as WebCit), and if that does not succeed, it will automatically
169 generate a key and certificate.
171 It is up to you to decide whether to use an automatically generated,
172 self-signed certificate, or purchase a certificate signed by a well known
179 That's all you need to know to get started. If you have any questions or
