You can modify this page to allow the administrator of the VOLANO chat server to modify the applet properties from any Web browser. You must first allow write access to the applet property files and define an administrator password as follows:
Modify the Java security manager policy, defined in
conf/policy.txt
, to give the ConfigServlet write
access to the applet property files. Otherwise, you will get the following
error when trying to modify the applet settings:
java.security.AccessControlException: access denied (java.io.FilePermission webapps/ROOT/vcclient/english.txt write)
Define an administrator password by setting the VOLANO chat server
property admin.password
in the server properties file,
which is the file conf/properties.txt
by default. You will
be prompted for a name and password by the applet configuration servlet
after you click a link below. When prompted, you can use any name,
but the password must match the server's admin.password
value.
When adding administrator or monitor passwords to the server
properties file, conf/properties.txt
, make sure the
file is not publicly accessible through your Web server and is not
readable by others on your server system.
Only the vcclient
subdirectory should be accessible
through your Web server when the VOLANO chat server is installed
following the instructions in the Administrator Guide. You can
prevent others on the system from reading the file by modifying its
permissions. On UNIX systems such as Linux, Solaris, FreeBSD, and Mac
OS X, you can set its permissions by running the chmod
command below from the VOLANO chat server installation directory:
$ chmod 600 conf/properties.txt
After that command, the server properties file will have the
UNIX file permissions shown below when installed under a username
of volano
. This allows only the user logged in as
volano
, or programs (such as the VOLANO chat server)
running under the account, to read and modify the file:
$ ls -l conf/properties.txt -rw------- 1 volano volano 4560 2009-03-04 08:22 conf/properties.txt
After restarting the VOLANO chat server with an administrator password, click a link below to modify the corresponding applet properties:
