webmlmd - WebMLM interface to couriermlm

SINOPSIS

cp /usr/lib/courier/courier/webmail/webmlm /var/www/cgi-bin

webmlmd {[start] | [restart] | [stop]} {/etc/courier/webmlmrc}

DESCRIPTION

WebMLM is a service that offers an alternative web-based access to some kuriermlm
commands, as an alternative to submitting them via E-mail.

At this time, WebMLM implements requests to subscribe and unsubscribe from the mailing
list, and configuration of basic mailing list settings.

Before configuring WebMLM, the mailing list must be set up using kuriermlm(1). WebMLM is
not a separate application, it is an add-on to kuriermlm. WebMLM will not work correctly
until the mailing list is fully configured, and all .courier files, that correspond to
this list, are installed.

MAKLUMAT UMUM

WebMLM consists of three parts:

· A configuration file, (default: /etc/courier/webmlmrc) that enumerates all
kuriermlm-created mailing list directories for which WebMLM will offer its services
(a single instance of WebMLM can support multiple mailing list directories). The
configuration file also specifies the name of a local filesystem socket (a named pipe)
di mana webmlm and webmlmd programs talk to each other, and several other configuration
parameter.

· webmlmd is a background daemon process that reads the configuration file, creates the
communication socket specified by the configuration file, and listens for web
permintaan.

· webmlm is a small stub program which must be installed as a script in Apache http
server's cgi-bin directory. Apache runs the script to process every request received
from a web client/browser. webmlm reads web browser's request, reads the
configuration file, opens the communication socket file specified in the configuration
file, sends the request to the webmlmd daemon process, and waits for webmlmd's
response, which is forwarded to the web browser/client.

Nota
webmlm is originally installed in the /usr/lib/courier/courier/webmail directory,
and must be manually copied to Apache's cgi-bin directory. Most installable
Courier packages (including the Courier RPM package built using its default RPM
build script) have a separate subpackage that installs webmlm terus ke
cgi-bin directory. Installing the subpackage is all that's needed in those cases.

Use the following process to web-enable kuriermlm-managed mailing lists:

1. Configure the LISTNAME, LISTDESCR, LISTPW and URL kuriermlm list options.

2. Set up the webmlmrc configuration file.

3. Mula webmlmd, and arrange start it automatically during the system boot.

4. Memasang webmlm in your web server's cgi-bin directory.

CONFIGURE COURIERMLM SENARAI PILIHAN

Menggunakan "kuriermlm menetapkan direktori nama=nilai” command, for each kuriermlm senarai direktori
to set the following settings:

LISTNAME
The mailing list's short title, or caption. Example: “The courier-users mailing list”.

LISTDESCR
This is a longer, more verbose description of this mailing list. This setting is
displayed, as raw HTML, on the list's main page. This is an optional setting.

URL
The URL to the main page for this mailing list. You'll need to figure out what this
URL should be set to by planning ahead where webmlm gets installed, in the last step
in this installation process.

Selepas memasang webmlm in Apache's cgi-bin directory, the URL for the webmlm arahan
would probably be something like “http://nama pelayan/cgi-bin/webmlm”. The list's URL is
the name of the list's directory appended to webmlm's URL.

Contohnya, jika kuriermlm mailing list directory is /var/lists/devel-list, its
URL MUST be “http://nama pelayan/cgi-bin/webmlm/devel-list”.

LISTPW
This is the password to the mailing list administration screen. The password must be
set using the kuriermlm perintah.

Nota
We are not talking military-grade security, here! Do not recycle sensitive
passwords for this purpose. The password is saved, in plain text, in the options
file in the mailing list directory. You should consider removing the world read
and execute permissions on the mailing list directory. Changing the permissions on
the options file is ineffective, it will be restored the next time any
configuration setting is changed.

Furthermore, authorization for the administration screen is provided by storing
the list password in a browser cookie, which also gets transmitted over the
network, in the clear. Consider using SSL with webmlmd.

This is a simple password-based implementation. High levels of security require a
lot of care to set up, and are usually somewhat complicated to implement and
manage. Keep that in mind.

Put apostrophes around each option setting when running kuriermlm. Sebahagian besar
configuration settings (especially LISTDESCR) contain special shell characters and must be
dipetik.

SETTING UP THE WEBMLMRC CONFIGURATION FAIL

Lalai webmlmd configuration file is installed as /etc/courier/webmlmrc. The file
contains a description of each required configuration setting. Briefly:

PORT
The filesystem socket port file. This is a local filesystem socket that's used to
process web requests. The directory that contains the filesystem socket must either be
owned by the same userid that owns the kuriermlm mailing list directory, or webmlmd
must be started as root (in the next step of this installation process). The default
/etc/courier/webmlmrc configuration file sets the filesystem socket file to a Courier
directory that's only writable by root, so webmlmd needs to be started by root, in the
step step, in the default configuration.

Additionally, the filesystem socket port file must be accessible by the userid that
executes web cgi-bin scripts. This is the nobody user, in Apache's default
konfigurasi.

SENARAI
A colon-separated list of kuriermlm mailing list directories, as absolute paths. A
single instance of WebMLM is capable of handling multiple lists, provided that:

1. The names of all mailing list directories, the last components of all directories,
adalah unik.

2. All mailing list directories are owned by the same userid and groupid.

Otherwise, multiple, separate instances of WebMLM must be set up.

BERMULA WEBMLMD

Perintah berikut bermula webmlmd:

webmlmd start fail konfigurasi

This command should be added to your system start up script (replacing fail konfigurasi dengan
absolute pathname to the configuration file).

Nota
Most installable Courier packages (including the Courier RPM package built using its
default RPM build script) install a system startup script. The script invokes the
appropriate magical incantation if the configuration file (/etc/courier/webmlmrc) has
a non-empty LISTS setting. Initially, LISTS is empty and nothing happens. Once the
mailing list directories are defined, the startup script will take care of starting
webmlmd.

. webmlmd command returns immediately, it continues to run as a background daemon
process). To stop the daemon process:

webmlmd stop fail konfigurasi

Seperti yang dinyatakan sebelum ini, webmlmd must be either invoked as root, or under the same userid
that owns the mailing list directories, provided that PORT's directory is writable by the
ID Pengguna.

MEMASANG WEBMLM

Pasang webmlm program by either manually copying it from the
/usr/lib/courier/courier/webmail directory to your Apache's cgi-bin directory. Most
pre-built Courier packages typically do not have a /usr/lib/courier/courier/webmail
directory, but have have an optional subpackage that installs webmlm terus ke
cgi-bin directory

PELBAGAI WEBMLM INSTANS

Sometimes, very specialized environments may require multiple instances of WebMLM. For
example, to support mailing list directories that are owned by different userids. This may
not be supported by most generic, pre-built, Courier packages, and must be done manually.

memasang pelbagai salinan of webmlm
Make separate copies of the webmlm program, one for each instance of WebMLM. Install them
all in your web server's cgi-bin directory. This can be done with soft or hard links, but
there must be separate instances of webmlm.

Each instance of webmlm reads a configuration file whose name is formed by appending “rc”
to the command, and looking for the file in /etc/courier. For example, the unmodified
webmlm reads /etc/courier/webmlmrc. If a second copy named webmlm2 exists, it will read
/etc/courier/webmlm2rc.

Additionally, the optional WEBMLMRC_DIR environment variable overrides the /etc/courier
portion of the configuration filename. If webmlm finds that this environment variable is
set, its contents replace the “/etc/courier” portion. For example, a webmlm yang berbunyi
“/etc/lists” from WEBMLMRC_DIR will open the /etc/lists/webmlmrc configuration file.
Similarly, if its own name, in the web server's script directory, is webmlm2, it will open
/etc/lists/webmlm2rc.

Use Apache's “SetEnv” directory to set environment variables:

SetEnv WEBMLMRC_DIR /etc/lists

Use whatever mechanism makes sense for you to arrange a unique configuration file for each
salinan daripada webmlm perintah.
