2 C HAPTER 2 V10 New Features Debian support Portable Ubuntu support (requires openssl, libmysqlclient and aspell libraries). ODBC support on Linux with unixodbc (Oracle, Postgre SQL) php_tidy for PHP purple module for IM and libpurple, purpleserv new menu item added to Wizard: Display licence information support for PDO MySQL in PHP support for UTF-8 in PDO SQLite in PHP unified API makes all available functions accessible through apiobjectcall interface Mail Log Analyzer available (log importer only), requires to compile and install ODBC drivers

3 C HAPTER 3 Differences between Windows and Linux Versions Linux version and Windows one are the same feature-to-feature, including: LDAP and ActiveDirectory integration Avast! anti-virus with AutoUpdates Commtouch Anti-Spam LIVE engine (ctasd) MLA Mail Log Analyzer (importer daemon) SQLite3 database engine installed and used by default PHP5 with XCache, php_tidy and common libraries MySQL 5.1 native support (requires libmysqlclient) command line tool with direct access to API and server constants the same unified IceWarpServer API library (RPC, PHP, apiobjectcall) the documentation applies with some abstraction if using WebAdmin There are however differences given by the platform architecture: Administration GUI is non-native but runs under Wine installation script instead of installer wizard PHP is installed separately UnixODBC and DB driver installation required for Oracle 11, Postgre SQL 8, Firebird 2.1 no support for FastCGI and FastISAPI multi-threaded web server modes

4 C HAPTER 4 Migration from Windows to Linux 1. Save Windows configuration into MCB file (Backup configuration). 2. In Linux, restore configuration in WebAdmin. 3. The correct paths are converted and set automatically by IceWarp Server, so you do not have to set them. 4. Mount Windows drive and manually copy the email folders into Linux destination directory (by default /opt/icewarp/mail).

5 C HAPTER 5 Before Installation 1. Check available space on your disc, min. 150 MB is required. 2. Please check if your system has installed required packages. The IceWarp Server Dynamic Library Dependencies (see "IceWarp Server - Dynamic Library Dependencies" on page 44) chapter lists these packages, you can install only packages that are required by selected features. 3. Stop and remove from the init process every program which can use any network port required for the server. For example sendmail listens on the port 25 and the SMTP service would not be able to start. 4. You can create a new user for the server, for example "icewarp". If the server should listen on a privileged port, you can install this server under the unprivileged "icewarp" user and then start it under the root. The server will drop its privileges from the root to the installed user, but will be able to listen on the privileged ports.

6 C HAPTER 6 Installation Package The installation package is in.tar.gz format. The latest package can be always found on IceWarp website http://www.icewarp.com, in the Downloads section. Example: IceWarpServer-10.0.0_(2009-02-10)_RHEL5.3.tar.gz 1. Extract the package: [linux]$ tar -xzf IceWarpServer-10.0.0_(2009-02-10)_RHEL5.3.tar.gz 2. Chdir to the created directory: [linux]$ cd IceWarpServer-10.0.0_(2009-02-10)_RHEL5.3 3. Start the installation: [linux]$./install.sh 4. Follow the onscreen instructions.

7 C HAPTER 7 Running After installation, at least one domain and one user must be created first, otherwise the server will not work. You can use wizard.sh in the installation directory to create the initial domain and user. The initial user should be System Administrator one so you can log in into WebAdmin and manage settings. The IceWarp Server uses database for storing informations for accounts, antispam and groupware. Default databases are: Accounts: uses file system Antispam and groupware: SQLite You can change database type in wizard or using the Remote Administration tool for Windows or using WebAdmin. Also UnixODBC is supported, but you must compile the latest version from http://www.unixodbc.com/. The server was tested with UnixODBC with Oracle and PostgreSQL. Default listening port for webserver is 32000. Default http addresses are: WebClient: http://localhost:32000/webmail WebAdmin: http://localhost:32000/admin RPC: http://localhost:32000/rpc/ If you have problem running the server, please check log files in the./logs directory, there can be found logged errors of unsuccessful port binding or required library loading error.

8 C HAPTER 8 Installation Step-by-Step on CentOS 5.3 To install IceWarp Server on CentOS 5.3, follow these steps: 1. Check available disk space in volumes using df -h. 2. Verify installed packages using rpm -qa.

40 C HAPTER 9 Controlling IceWarp Server in Linux Starting server and/or services [linux]$./icewarpd.sh --start starts "icewarpd" and automatically starts all services, except PHP, which is started when first HTTP request arrives. [linux]$./icewarpd.sh --start control gw im pop3 smtp all starts the selected service or all services. If "icewarpd" is not already running, this command does not start it. If the control is started, it starts PHP on the first HTTP request. Stopping server and/or services [linux]$./icewarpd.sh --stop stops all running services, stops "icewarpd" and also PHP. This is the command for complete server shutdown. [linux]$./icewarpd.sh --stop control gw im pop3 smtp all stops selected service or all services. This command causes PHP stop together with control and does not stop "icewarpd". Service icewarpd functionality When the "icewarpd daemon" is running, it: checks every 1 minute whether all started services are running. If not, service is re-started. Commands table Action \ Platform RHEL 4 and 5 Other distributions Start all services and icewarpd [pc]$ service icewarp start [pc]$./icewarpd.sh --start Stop all services and icewarpd [pc]$ service icewarp stop [pc]$./icewarpd.sh --stop Restart all services and icewarpd [pc]$ service icewarp restart - Start specific service [pc]$./icewarpd.sh --start x [pc]$./icewarpd.sh --start x Stop specific service [pc]$./icewarpd.sh --stop x [pc]$./icewarpd.sh --stop x Check specific service [pc]$./icewarpd.sh --check x [pc]$./icewarpd.sh --check x Run wizard [pc]$./icewarpd.sh [pc]$./icewarpd.sh

Possible services are: control, gw, im, pop3, smtp, all. Error! No text of specified style in document. 41

42 C HAPTER 10 IceWarp Server Administration Via Win32 GUI - download and install the latest Win32 GUI from the IceWarp website http://www.icewarp.com, connect to IceWarp Server the same way you would do for Windows MailServer. commandline wizard used for quick setup and easy tasks, scriptable for more complex tasks. Wizard can create the initial account, generate unique SSL certificate and set up database connection, install license and manage IceWarp Server services. cd /opt/icewarp./wizard Web administation frontend browse to http://<your.server.here>:32000/admin/

43 C HAPTER 11 Installation of Aspell Dictionaries IceWarp Server uses Aspell (version 0.60.6) as a spell checker. It requires dictionaries for version 0.6 (or higher). You can download these dictionaries (free) from http://aspell.net/. To install a dictionary, use the./scripts/install_aspell_dictionary.sh script. Use the dictionary file name as a command line parameter. Example of the command for the Czech dictionary installation: [linux]$./scripts/install_aspell_dictionary.sh /home/user/aspell6-cs-20040614-1.tar.bz2 After dictionary installation, this new dictionary will not be available in WebClient. To fix it, you have to add a record about this dictionary to the WebClient configuration file:./config/_webmail/spellchecker.xml The record format is as follows: <aspell_dictionary_id>name_in_webmail</aspell_dictionary_id> Example: New IceWarp Server installation has in the./config/_webmail/spellchecker.xml file one record for implicit English dictionary that is included in the installation: <en>english</en> After installation of the Czech dictionary, it is necessary to add the following record: <cs>czech</cs> Use similar records for other languages. NOTE that the./config/_webmail/spellchecker.xml file is created after the first login to WebClient and after displaying of the dialog for spell checker setting. This dialog is accessible via the Settings menu item within the email composer window.
