16.2.4 Cache Peer In the “Cache Peer” screen of “Cache”, we can configure to communicate with other Proxy Servers. This configuration is possible for the communication with proxy servers on upper levels or on the same level. 6.2.5 Multi Router Traffic Grapher (MRTG) In general, Multi Router Traffic Grapher (MRTG) graphically shows performance analysis of cache service, including analysis of cacheServerRequests, cacheServerErrors, cacheServerInKb, cacheServerOutKb, and CPU utilization. As shown in the figure below: In addition, if you click any small graph in All targets Overview, the cache traffic analysis on daily, weekly, monthly, and annual basis will display as shown in the figure below:
2 6.2.6 Cache Management You can check whether the cache is operating properly via Cache Manager Interface. Click “Statistics” in Cache service menu. The following screen will appear: Click “Continue” button directly (it is unnecessary to complete Manager name and Password since the system will enter the data automatically). The options of Cache Manager will appear as shown in the figure below, wherein “IP Cache Stats and Contents” and “Cache Client List” are frequently used by managers, and thus the rest of the Cache Manager options will not be described here.
3 1. IP Cache Stats and Contents – shows all of the websites visited by the client-end and the corresponding IP addresses, plus the log data of pre-caching, as shown in the figure below: 2. Cache Client List – shows all of the Client-end information on the used cache service, as shown in the figure below:
4 6.3 DHCP Service DHCP (Dynamic Host Configuration Protocol) is a communication protocol used to distribute IP addresses and other configurations between Client PSs and DHCP server. It mainly features to enable one computer broadcasts through its own MAC address to obtain configurations related to IP, Netmask, Default Gateway and DNS. Thus a network administrator only needs to configure DHCP server, so that Client PC can automatically obtain IP related configurations through DHCP protocol, saving efforts to configure on each client PC.DHCP and NAT (transferred Virtual IP to legal IP) are not directly related. Please make sure not to error. DHCP servers are all easy to use and set up. Therefore, if your PC fails to obtain an IP address, the problem generally originates in such PC devices as network cabling, NIC of PCs, HUB, switches, NT servers, printer servers, or / and interweaving of internal and external networks. 6.3.1 Steps of DHCP Configuration 1. Enable DHCP Click “Service” in the “System Management Tools” screen and select Enable for “DHCP” as shown in the figure below:
52. Default Value of DHCP Service Configuration Then click “DHCP” in the “Service” screen. A NIC screen showing that DHCP is enabled will appear as shown in the figure below: The above figure shows that the NIC (eth1) had enabled DHCP. If you want to use other NICs to enable DHCP, you can select “Enable” for the specified NIC on the “Configuration” screen as shown in the figure below: 3. Change in NIC Configurations of DHCP In the “Configure” screen of “DHCP”, we can choose to carry out related configurations for the NIC that starts the DHCP. As shown in the figure below, check the Sub-domain “192.168.2.0” (pointed out by the arrow) to enter the configuration screen of that NIC. In the NIC Configure screen with DHCP of 192.168.2.0 as shown below, we have set up such parameters as “172.16.100.1” for the server, “172.16.100.1” for the router, and the IP-address range available in the DHCP server. These settings are related information provided by the DHCP server when DHCP clients request the
6server for an IP address. 6.3.2 DHCP Client-End Configuration Client-end configurations are very simple, just requiring a few of steps as shown below: 1. DHCP Configuration (Microsoft Windows 2000 taken as an example here) Click the right mouse button on “My Network Places” and select “Properties”. Then select “TCP / IP” Æ NIC (e.g. NE2000). Except selecting “Automatic Obtain IP Address” (Shown as in the figure above) on “IP Address”, you do not need to configure related options. Click on “OK”, Client PC will reboot. After rebooting computer, you can use command winipcfg to check if a set of IP values automatically obtained.
76.3.3 DHCP Logging After selecting “Logging” of “DHCP”, the system will display the utilization status of DHCP clients, such as IP addresses and lease time, MAC addresses, and host names of the client PC, so that MIS staffs are able to conduct related administration, as shown in the figure below: 6.4 DNS Select “DNS” in “Service”: (Related configurations below are for demonstration only) As shown in the figure above, configuration list for “DNS” appears. The list shows all current configurations of “DNS”. 6.4.1 Configurations The configurations allow administrators to add primary domain or sub-domain.
8 Select “New Master Zone” to add a new primary domain: Note: 1. (master) eflash.com.tw, (master) 192.168.2, (master) 172.16: are the Forward and Reverse of DNS. “(master) eflash.com.tw” is the Forward Domain Name Analysis of this domain, while “(master) 192.168.2” and “(master) 172.163” are its Reverse Domain Name Analysis.
9 The two figures above are the detailed configurations of the Forward Domain Name Analysis of “(master)eflash.com.tw”. The two figures above are the detailed configurations of the Reverse Domain Name Analysis of “(master)172.16”. 2. The system will automatically apply newly configured DNS configurations after you make a change in all of the aforementioned settings.
106.5 FTP Actually, FTP stands for “File Transfer Protocol”, which allows LAN or Internet users to upload and download files and data in a snap, and thereby makes network HD storage and resource sharing possible. 6.5.1 Steps of FTP Configuration 1. Enable FTP Click “Service” in the “System Management Tools” screen, select “Enable” FTP as shown in the figure below: 2. FTP Configuration Then click “FTP” in the “Service” screen, and you will see a FTP service default offered by the system. As shown in the figure below, the system has enabled FTP server, disabled root user, enabled Anonymous and disabled Anonymous Incoming: A click of “Configuration” in the “FTP” screen enables you to change FTP configurations. If you want to enable ROOT user to use FTP as well, check “Enable” for root user, as shown in the figure below:
11 6.5.2 Anonymous Configuration Click “Anonymous FTP” in the “FTP” screen. As shown in the figure above, configuration list for “Anonymous FTP” appears. This list shows all the applied configurations of “Anonymous FTP”. This item is used to enable each configuration. ※ Note: “Anonymous FTP” means that the FTP is obtainable via universal user account, requiring no account authentication. Whether to enable this function depends on “Anonymous FTP status”. The universal user account here only has permission of reading files, and it is the “Anonymous FTP Incoming” that decides whether granting permission of writing files. 6.6 Mail In generally, Mail configurations refer to the files under the directories of /etc/mail/sendmail.cf, /etc/aliases, and /etc/mail. If you fail in receiving any mails, it is often a result of incorrect DNS settings or inconsistency between the Forward and Reverse Domains of the domain name you have applied. However, the failure may be
12sometimes caused by the mistakes of these configuration files’ content or those of file permissions. 6.6.1 Mail Configuration It is mainly used to configure email size limit. Please select “Configure” in “Mail Service” interface. Then a screen will appear as follows: Now you can configure mail size; if you do not specify, mail size will be 0 Bytes. (Note: The unit is Bytes. So if you want to configure as 1MB, you should configure as 1024000 Bytes.) 6.6.2 Mail Alias Click on “Mail Alias” you can specify the alias for whom to receive the mail. For example; If you specify “Johnny, Richard, James” as the alias for “Sales Team”. All the mail to “Sales Team” will be forwarded to Johnny, Richard and James. The screen will appear as follows: 6.6.3 Mail Access List Configuration In general, the settings configure the accessible IP address block or domain name for the mail. During installation, the management interface will automatically set up a default value for the properties here. Therefore, in general, it is unnecessary to change these settings unless you want to edit, add or delete some DNS configurations yourself. Please select “Mail Access List Configuration” in “Mail” of the “Service” interface. Then a screen will appear as follows:
13 You can configure accessed domain range for mail service. Access service is not available for those not listed on the Access List. The range can be Domain Name or IP address. (Note: The rule fields of the system allow continuous entry of data, without any limitation on the space shown in the screen.) 6.6.4 Configure Mail Domain for Localhost Here you can configure the domain names or other names that are available in the host, with default values automatically configured during installation. Therefore, in general, it is unnecessary to change these settings unless you want to edit, add or delete some DNS settings by yourself. Select “Localhost” in “Mail” of the “Service” interface. Then a screen will appear as follows:
14 (Note: The rule fields of the system allow continuous entry of data, without any limitation on the space shown in the screen.) 6.6.5 Configure Email-Relay Domain Here you can configure the domain or IP address block to have the mail service accept relayed emails. During installation, the management interface will automatically configure a default value for the properties here. Therefore, in general, it is unnecessary to change these configurations unless you want to edit, add or delete some DNS configurations yourself. Please select “Email-relay Domain” in “Mail” of the “Service” interface. Then a screen will appear as follows:
15 The range here can be on a basis of domain names or IP addresses. (Note: The rule fields of the system allow continuous entry of data, without any limitation on the space shown in the screen.) In order to prevent from any unauthorized utilization of mail relay. Maat system included an authentication facility to challenge user with user ID and password. When user’s domain that is not in “Relay” list, system will prompt for user ID and password. User will be denied if authentication does not successful. If user wants to enable the authentication facility please refer to related Email application (such as Outlook Express) to make appropriate configuration. 6.6.6 Configure Group Mail Domain In general, you can have emails sent in groups by configuring the settings here. In other words, whenever you send a mail within a domain, the mail will be delivered to every body of the same group as long as you keyed in a “group name @ mail server name” for the mail. Of course, you have to know the group’s name before doing so. Please select “Group Mail Domain” in “Mail” of the “Service” interface. Then a screen will appear as follows:
16 The range here can be on a basis of domain names or IP addresses. (Note: The rule fields of the system allow continuous entry of data, without any limitation on the space shown in the screen.) 6.6.7 Mail Queue The main function of Mail Queue is to display all mails waiting for sent (shown as follows). You can click “Delete all mail in queue” to delete all mails waiting in queue. 6.6.8 Mail Logging(SendMail) By clicking “Logging(SendMail)” of “Mail”, you can view whether the mail service is operating normally, whether there is a person delivering junk mails, or whether there are jammed mail boxes, so that you can take countermeasures in time, as shown in the figure below:
17 6.6.9 Mail Logging(Simple) By clicking “Mail Logging(Simple)” of “Mail”, you can view the mail service in simpler format, It include “From” , “To” , “ID” , “Size” and “Subject” as shown in the figure below: 6.6.10 Mail for root & sysop Managers After you finish configuring the system, “rootalias” will be set up automatically as a default account and there is no way to delete it. This account is mainly used to receive mails for sysop and root; in other words, whenever there are mails sent to the mailbox of sysop or root, the mails will be delivered to the rootalias account. Therefore the root and sysop managers are expected to use this account to receive mails. Please be kept in mind to periodically clean the mail for “rootalias”. The “System Logging” in “System” GUI will come up with message as “save email panic and reject anywhere” if mailbox for “rootalias” became full. But this would not interfere other mail operation of Maat system. 6.6.11 Mail Tools Every Maat user have requirement to change their owned password and other action on mailbox. They will connect to Maat home page through the URL as http:// Maat’ IP Address. The diagram show as below:
18 Click on “Mail Tool” button on the upper right side of screen. The Mail Tool management screen show as below: Change Password: It allows you to change user password. Mail Forward Setup: It allows you to set mail forwarding to another mail account. Mail Box Quota Check: It allows you to check status of mail quota. Clean Mail Box: It allows you to clean up mailbox content. 6.7 MRTG (Multi Router Traffic Grapher) Traffic Monitoring MRTG (Multi Router Traffic Grapher) – MRTG is the web traffic statistics software with high popularity. One of its features is that it can draw a web-traffic statistic chart at anytime. We can use MRTG retrieve the SNMP information from such network equipments as routers and switches, and thereby enable MRTG to generate traffic information. 6.7.1 MRTG Configuration To configure MRTG is quite easy. If you want to perform MRTG traffic monitoring on host, you only need to enter IP address. Remember to enable SNMP function. (Note: The
19system default is “Enabled” SNMP. If not, please enable on “System Management” of “System Management Tool”.) Click on “MRTG” from “Service” to begin traffic monitoring, and then click on “Configure”. As shown in the figure below, full in IP address in the “MRTG Target” field, and then click on “MRTG Rebuild” to complete the configuration. (Note: Here the MRTG address stands for local host or other node needing traffic monitoring.) 6.7.2 MRTG Logging In essence, MRTG operates like a kind of simple network management software. It uses SNMP to detect (or query) the network equipments with SNMP you specified, and compile statistics the traffic of these equipments every five minutes, based on which a statistics graph is generated. The most fascinating feature of MRTG is that we can easily comprehend the actual web traffic from the statistics graph alone. Here you can see its exhaustive traffic graphs. Click on “Logging” from “MRTG”, you can see basic description of host system and a traffic chart. The chart shows only some representations. (If the network facility is only a NIC, you will see a chart representing the traffic on the NIC ) as shown in the figure below:
20 Click one of the traffic graphs above and then a screen will be shown as follows: The figure above displays MRTG traffic monitoring, which generate traffic graphs on a basis of days, weeks, months, and years. In addition, it separately presents a graph of Max In / Out, Average In / Out, and Current In / Out, offering administrators with referential data to conduct system tuning and improve network performance. 6.8 NAT NAT (Network Address Translation) allows you to define a virtual IP address in a private network whenever you need to do so, without the hassle of applying for a realistic one. Each PC in a private network communicates with each other via a private (i.e., virtual) IP address. When you want a private PC to communicate with the public Internet, you can use a NAT-enabled device (such as routers or the host itself) to translate the private IP address into a legal IP address (i.e., an officially applied IP address) to conduct communications. NAT can resolve most of the problems of moving private data
21transparently across the Internet. 6.8.1 Configuration It is also very simple to configure NAT in this host. To start, please click “Service” and “NAT” from “System Management Tools”. Then click “Configurations” to configure which NIC is for the public network and whether to enable NAT and whether to log, and log directory、size and times as shown in the figure below: 6.8.2 Port Redirection Port Redirection function can redirected the packet externally connected to specified port number to specified host. This makes server for intranet available for external use. Also, it prevents server for intranet from direct exposure and attack from outside. Click “Redirec Port” from “NAT” as shown in the figure below: Click the “Insert New Rule” and input the detail information as shown in the figure below:
22 6.8.3 NAT Logging Click ”Logging” from “NAT”, then you can see the user records of NAT as shown in the figure below: 6.9 NetBios Services NetBios Services features to make all users using Windows operating system see and share local file services on My Network Places. 6.9.1 NetBios Configuration Click “Service” from “System Management Tool”, then click “Configure” from “NetBios Services”. You can configure the following item: Netbios Name: It’s the host name configuring from “Network Interface”. Comment: The “Comment” is not mandatory. Allow Hosts/Networks: It’s to designate the host or network that allow to access this
23Maat file server. Netbios Interface: It’s to activate the network interface for file share function. Workgroup: It is the workgroup name that designate in Microsoft network environment. Share Printer: It allowed you to “Enable” or “Disable” the printer share function. Codepage: It’s to define the language code that you using in your nation. For example, in Japan area you will choose the “Japanese” to correctly show any file name that in Japanese word. 6.9.2 Volume Management Click on the “Volume Management” you will see as follow: Choose the Volume Name you going to configure. Here to choose “pub”. The screen show as below:
24 You are allowed to modify the parameter for specific volume. There is default value shown as above. 6.9.3 Connection Click “Connection” from “NetBios Services”; you can see the whole user connections established as shown in the figure below. They include “Volume Name”, “Machine”, “IP” and “Date”. 6.9.4 NetBios Logging Click “Logging” from “NetBios Services”; you can see if NetBios starts normally as shown in the figure below:
256.10 PostgreSQL PostgreSQL is a powerful object associated database containing many support capabilitites that are not provided by other databases. PostgreSQL features its support to various programming languages and provides commonly used accesses such as ODBC and JDBC. It also provides excellent support to Chinese. For the information of technical support, please refer to our official website: www.postgresql.org. 6.10.1 Database Admin This system provides a simple and easy-to-use database administration system phpPgAdmin. To create a new database, or select or insert views in the database or table, users need only to click their mice several times and enter the required name as shown in the following figure. 6.10.2 Server Access Admin This function is used to configure who may connect to PostgreSQL to use the database. To execute the configuration, select the database you want to configure and enter the address and netmask. You may then select trust to pass the configuration or select reject to block it in Authentication Mode.
26 6.11 MySQL The Maat supported MySQL database from release of v3.01. MySQL database is more friendly and simple for programmers even their functions are very similar to PostgreSQL.

As the same as phpPgAdmin in PostgreSQL, The Maat also provided phpMyAdmin for MySQL database management. It is very simple and easy to create, select or insert the database table. Please refer to the following screen: 6.12 SSH SSH is a simple way to provided secure transmission of remote login session. It encrypted the command word and transmission data to prevent from any data monitoring. We are recommend you to use the SSH instead of Telnet to benefit the better security communication. 6.12.1 SSH Configuration Click “Configure” from “SSH” service. You have choice to select “Enable” or “Disable” the SSH function. (For security issue, we recommended you to “Enable” the SSH
27function) 6.13 TELNET Telnet is a host, enabling login into remote-end host from near-end terminal (For example using Windows built-in telnet or other Terminal Freeware such as NetTerm or MultiTerm.) 6.13.1 TELNET Configuration Click “TELNET” from “System Management Tools”. After clicking “TELNET Configure” you can optionally choose to start this function or not (For safety consideration it is recommended to close this function.) As shown in the figure below: 6.14 Web Mail Open WebMail basically provides the same functions as other mail servers. The only difference is that it shows mails on web pages, which provides access flexibility for any location, any time and easy-use. No matter where users are, they need only browser at hand, then they can send and receive their own mail as they like.
286.14.1 Operation Procedure to enter Open WebMail Open browser directly to enter the system’s “hostname•domain” or “IP” in the web address column. Remember not to add “10000” and directly enter the system’s main screen.

38 Chapter 8 Timefinder Timefinder is mainly used to backup and recover system data files. As for user data (such as homepage and mails) tape driver and disk array are needed to provide protection. The focus of host system design is an Internet Server, not a File Server. So the major function of Timefinder is to protect system’s data files. Timefinder features four main operations. The functions are divided into backup and recovery as shown in the Figure below: Among them, “Timefinder from Browser” enables users to automatically upload data （browserÆ host）after clicking, especially when using uploaded function of browser. If you have any difficulty when operating Timefinder, it is mostly because MIME of your current browser is modified. Please reinstall browser. Usually when you modified system settings or used management interface to change various functions and tested, you need to backup your Timefinder. If you are still at testing period, please do not backup the system data; otherwise the system will be unstable. That is why Timefinder did not activate automatic backup. Timerfinder needs 200-300K to backup, Though the space is not considerably large, backup can include the settings of the whole system (except homepage and mail) and automatically keep ten times. The old ones will be automatically deleted when the system is restarted next time. Timefinder’s recovery function can not only recover the system settings, but also correct user directory with kernel (in case that accounts of system password files exceeded the number stored in current hard disk). Also it can correct the causes resulting in shutdown of system, such as /tmp、/var、/lost+found.（Note: The function enhancement of Maat kernel is finished. But these are not the original kernel functions for FreeBSD.）
39The following operations are quite easy. Flow chart and figures are provided to help users understand. 8.1 Backup to Host Select “To Host” on “Timefinder” of management interface, as shown in the figure below: Click “OK” to complete backup. 8.2 Backup and Download Select “To browser” on “Timefinder” of management interface, as shown in the figure below: You can change directory and name and click “Save”.
40 Click “Save” as shown below: Now “Backup to Current Computer” is completed. Please remember the saved directory and file names for next restore. 8.3 Timefinder from Host Select “From Host” on “Timefinder” of management interface, as shown in the figure below:
41 Click on the time you want to restore and click ” Submit”. This means “Timefinder from Host” is completed. The system will be rebooted and restored to your selected time point. 8.4 Timefinder from Browser When you select “From Browser” from “Timefinder” as shown in the Figure below: Click “Browse”, the Figure below appears. Select restored file as shown in the Figure below:
42 Click ” Submit” to begin restoring files. When it has finished, the system will reboot.
