Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a consoleless device initial setting system, an initial setting method, and a program, and more particularly to a technique for executing server settings from a client connected to the server via a network.
[0002]
[Prior art]
In a network environment connected by the TCP / IP protocol, each network device such as a storage server and a network printer is assigned a unique and fixed MAC address, but a logically unique IP address is assigned to the network device. Data communication is being performed as the destination. Therefore, since data communication cannot be performed with a network device for which an IP address is not set, network-related setting information including an IP address must be set before communication.
[0003]
The IP address is composed of a 32-bit or 64-bit numeric string, and the host (machine) is identified by this numeric string. However, since it is difficult for humans to use the host, it is difficult to use characters. Use what is expressed in columns. This is called a host name. The host name is composed of a so-called hierarchical domain name and a machine name, for example, “machine1.domein2.domein3”. In this example, the machine name is “machine1”, and the domain name is composed of a character string “domein2.domein3” consisting of a series of names (labels) separated by periods.
[0004]
In the network device, the initial setting of the machine name, the IP address, and the subnet mask and the setting change after the initial setting are set using a console including an input device and a display device connected to the network server. However, among network devices, devices that do not normally require a console, such as a server, except for special cases such as incorporation into a system, have been used in a form without a console (called console-less).
[0005]
According to Japanese Patent Application Laid-Open No. H11-249989, when setting information of an option I / F card connected to a LAN (local area network), it is determined whether setting information including an IP address has been set. When the setting is not set, the setting is executed by broadcasting, and when the setting is already set, the setting is executed by the normal unicast. However, a PING is issued and responded to the option I / F card instructed to determine the setting state. It is determined whether the IP address has been set or not. However, Japanese Patent Application Laid-Open No. H11-249989 does not specifically describe what means is used for performing broadcast communication.
[0006]

[0007]
[Problems to be solved by the invention]
When performing initial setting or resetting for a server without a console, provide a small special display device or input device, or temporarily set the display device or input device to a network server at the time of setting. There is a problem that must be connected to. Further, the user has to move to the installation location of the network server and perform the setting operation.
[0008]
In Japanese Patent Application Laid-Open No. H11-249989, when executing the initial setting of the option I / F card, a PING is issued to confirm whether the IP address of the option I / F card has been set. The judgment is made based on the response. Therefore, there is a problem that extra communication must be executed on the LAN to confirm the setting state of the IP address.
[0009]

[0028]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a configuration example of the system of the present invention. In the system of FIG. 1, two server devices 10 (server device 10-1 and server device 10-2) and one client device 20 are connected to LAN 29. In addition to this, a server or a client may be connected to the LAN 29, or a device such as a printing device or a router may be connected, and the device to be connected to the LAN 29 is not specified.
[0029]
The server device 10 is an information processing device having a communication function of providing services such as network management, and it is assumed that a display device and an input device are not connected. The server device 10 exchanges a UDP (user datagram) between the client 10 via the LAN 29 and a setting information unit 11 for holding setting information relating to the network, a setting changing unit 12 for changing and controlling the setting information in the setting information unit 11. protocol) communication and accepts and processes the request for initial setting. The setting change unit 12 and the setting reception unit 13 are often realized by a program.
[0030]
UDP is a transport layer protocol of the TCP / IP model, and is a connectionless protocol that does not have a retransmission function or a flow control function like a connection-type TCP (transmission control protocol). Equipped with a broadcast function that interferes with control. In the UDP communication according to the embodiment of the present invention, "30000h (hexadecimal)" is used as the port number.
[0031]
The setting information section 11 shows a logical holding function, and it is not necessary to actually hold the same in the same storage means. The setting information held by the setting information unit 11 includes information related to the network such as a machine name, a MAC address, an IP address, and a subnet mask. The setting change unit 12 has a setting status flag indicating whether or not the setting information has been set. The setting status flag is set to unset in an initial state when the server device 10 is shipped, and when the setting is completed. It is already set.
[0032]
Note that the setting change unit 12 uses the MAC address of the setting information as the machine name in the unset state for reading the machine name in the setting information 11 so that it can be identified that the setting is not set. As another method of identifying the unset state, the machine name of the setting information may be set to be the same as the MAC address. In this case, it is not necessary to replace the setting state flag and the machine name.
[0033]
The client device 20 performs a UDP communication with the server device 10, collects and displays setting information of each server device, and sets a inputted setting information in the server 10, and a display device 22. And an input device 23. The server setting unit 21 is often realized by a program.
[0034]
Next, the operation of the embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a flowchart showing an operation of initial setting according to the embodiment of the present invention, and FIG. 4 is a flowchart showing an operation of resetting according to the embodiment of the present invention.
[0035]
First, an operation of initial setting for the server device 10-2 will be described with reference to FIG. First, the user physically connects the server device 10-2 to be newly incorporated in the LAN 29 to the LAN 29. At this point, the server device 10-2 has not set network-related setting information. Then, the user activates the server setting unit 21 in the client device 20 which has already been incorporated into the LAN 29 and set.
[0036]
FIG. 3 shows an example of an operation screen displayed on the display device 22 by the started server setting unit 21 when the user starts the server setting unit 21 in the client device 20. In FIG. 3, server list information such as a machine name and an IP address shown in FIG. 3 is not displayed.
[0037]
When the user operates the automatic discovery button in FIG. 3, the server setting unit 21 sends out an automatic discovery request to the LAN 29 by UDP broadcast communication (S51). The UDP broadcast communication is issued on the LAN 29 by specifying the port number “30000h” without specifying the communication destination. The UDP broadcast communication of the automatic discovery request is received when the setting receiving unit 13 of each server device 10 recognizes the port number “30000h”. In the subsequent UDP broadcast communication, the port number is similarly set to “30000h”.
[0038]
When receiving the UDP broadcast communication of the automatic discovery request, the setting receiving unit 13-2 checks whether the setting change unit 12 is running. In this case, since the setting change unit 12 is running, it passes the setting information read request to the setting change unit 12-2 (S52). ). Upon receiving the read request, the setting change unit 12-2 reads the setting information from the setting information unit 11-2, confirms that the setting is not set from the setting state flag, and sets the setting information with the same machine name as the MAC address. It returns to the receiving unit 13-2 (S52). The setting receiving unit 13-2 sends the read setting information as UDP broadcast communication of an automatic discovery response (S52). If the machine name of the setting information of the unset server device 10-2 is set in advance to be the same as the MAC address, the setting change unit 12 only needs to return the information read from the setting information unit 11 as it is.
[0039]
The server setting unit 21 of the client device 20 receives the UDP broadcast communication of the automatic discovery response returned from each server device 10, and creates server list information based on the received setting information. In this case, the setting information of the server device 10-2 is read as the machine name = MAC address because the server device 10-2 has not been set. When detecting the machine name = MAC address, the server setting unit 21 sets the machine name to “not set”, creates server list information, and displays it on the display device 22 (S53). The setting display screen 31 shown in (1) of FIG. 3 shows how the server list information is displayed at this time.
[0040]
When the user looks at the screen in FIG. 3, the machine name of the server device 10-2 is displayed as "unset", so that the user can immediately know the server device 10-2 to be set. When the user selects a server whose machine name is “unset” on the screen, inputs a machine name, an IP address, and the like from the input device 23 and operates the setting change button 36, the server setting unit 21 sets the input setting information. And the MAC address of the server device 10-2 of the setting destination is transmitted by the UDP broadcast communication of the setting change request (S54).
[0041]
Upon receiving the UDP broadcast communication of the setting change request and confirming that the setting change request is addressed to itself from the MAC address, the setting receiving unit 13-2 passes the setting change request to the setting changing unit 12-2 (S55). The setting change unit 12-2 registers the passed setting information in the setting information unit 11-2 (S55). When the registration of the setting information is completed, the setting changing unit 12-2 sets the setting state flag to the already set state, and the setting receiving unit 13-2 returns a setting change response by UDP broadcast communication (S55).
[0042]
Upon receiving the UDP broadcast communication of the setting change response, the server setting unit 21 transmits a UDP broadcast communication of a restart request to restart the server device 10-2 (S56). When the setting receiving unit 13-2 receives the UDP broadcast communication of the restart request and confirms that the request is the restart request addressed to itself from the MAC address, the setting receiving unit 13-2 returns the UDP broadcast communication of the restart response, and then returns to the server device 10-2. Is restarted (S57).
[0043]
Upon receiving the UDP broadcast communication of the restart response, the server setting unit 21 displays the end of the initial setting on the display device 22 (S58), and the user confirms the end of the initial setting. The server device 10-2 starts up in a state where the network-related settings such as the IP address are set by the restart (S59), and thereafter, the unicast communication in which the destination is specified by the IP address is also possible.
[0044]
In this way, the client device 20 collects the setting information of each server device 10 and displays the server list information by the UDP broadcast communication in which the communication destination is not specified by the IP address, and the user refers to the display and sees the unset server device. Since the server device 10 is equipped with the setting change unit 12 and the setting accepting unit 13, the server device 10 can transmit the network-related information from the client device 20 equipped with the server setting unit 21 even without a display device or an input device. You will be able to make settings.
[0045]
Next, an operation of resetting the server device 10-2 will be described with reference to FIG. At this time, the server device 10-2 has set the network-related setting information such as the IP address, that is, the setting state flag is already set. First, the user activates the server setting unit 21 in the client device 20 which has already been incorporated into the LAN 29 and set.
[0046]
When started, the server setting unit 21 displays the screen shown in FIG. However, the server list information is not displayed at this time. When the user operates the automatic discovery button 35, the server setting unit 21 sends out an automatic discovery request to the LAN 29 by UDP broadcast communication (S61). As in the case of the initial setting, the UDP broadcast communication is issued on the LAN 29 by specifying the port number “30000h” without specifying the communication destination.
[0047]
When receiving the UDP broadcast communication of the automatic discovery request, the setting receiving unit 13-2 passes a read request for setting information to the setting changing unit 12-2 (652). The setting change unit 12-2 receives the read request, reads the setting information from the setting information unit 11-2, and returns the setting information to the setting receiving unit 13-2 as it is in the already set state (S62). The setting receiving unit 13-2 sends the read setting information as UDP broadcast communication of an automatic discovery response (S62).
[0048]
The server setting unit 21 of the client device 20 receives the UDP broadcast communication of the automatic discovery response returned from each server device 10, and creates server list information based on the received setting information. In this case, since the setting information of the server device 10-2 has been set, the setting information such as the machine name and the IP address is displayed as it is on the display device 22 as the server list information (S63). The setting display screen 32 shown in (2) of FIG. 3 shows how the server list information is displayed at this point.
[0049]
When the user selects the server device 10-2 (machine name = NECSAN) to be reset on the screen, inputs information to change the machine name, IP address, and the like from the input device 23 and operates the setting change button 36, The server setting unit 21 transmits the setting information input by designating the IP address of the server device 10-2 of the setting destination by the UDP unicast communication of the setting change request (S64).
[0050]
When the setting reception unit 13-2 confirms that the UDP unicast communication of the setting change request is a setting change request addressed to itself from the destination IP address, it passes the setting change request to the setting change unit 12-2 (S65). . The setting change section 12-2 resets the setting information section 11-2 with the passed setting information (S65). When the setting information is reset, the setting receiving unit 13-2 returns a setting change response addressed to the IP address of the client device 20 by UDP unicast communication (S65).
[0051]
Upon receiving the UDP unicast communication of the setting change response, the server setting unit 21 displays the end of the resetting on the display device 22 (S68), and the user confirms the end of the resetting. Thereafter, if necessary, the user may restart the system connected to the LAN 29 or restart the server device 10-2, but the method is not particularly limited. For example, in order to restart the server device 10-2, a button for restarting is provided on the setting display screen of FIG. 3 and the restart is started from here, and the server setting unit 21 and the setting receiving unit 13-2 of FIG. What is necessary is just to operate like steps S56-S59.
[0052]
As described above, the setting change unit 12 and the setting receiving unit 13 are mounted on the already set server device 10, so that even if there is no display device or input device, the client device 20 having the server setting unit 21 can perform network-related operations. It becomes possible to reset information setting information.
[0053]
As described above, in the procedure for initial setting or resetting of the network-related information of the server device 10, the machine name of the unset server device 10 looks the same as the MAC address or is set in advance. Only by checking the setting information of each server device 10 collected by communication, it is possible to easily determine whether the setting has been made or not. Thus, after the user issues a setting instruction, the client device 20 issues a command for confirmation to the instructed server device 10 in order to determine whether to perform the initial setting operation or the resetting operation. This eliminates the need to issue a procedure (for example, PING) to confirm whether network-related setting information such as an IP address has been set.
[0054]
In the above description, the operation for the server device 10-2 has been described, but the same operation is performed for the server device 10-1. The present invention can be applied to a device such as a shared printer connected to a network as long as the device has the functions of the setting information unit 11, the setting change unit 12, and the setting receiving unit 13 included in the server device 10. The setting can be made from the client device 20 in the same manner as described above.
[0055]
Further, in the above description, the machine name of the setting information of the server device 10 is set to be the same as the MAC address to respond to the automatic discovery request in order to identify whether the setting is unset or already set. The identification may be performed by another method. For example, information indicating that no setting has been made may be incorporated in the response, or the machine name or the IP address may be set according to a predetermined rule.

【The invention's effect】
Since the initial setting or resetting of the network information of a server device without a display device or an input device can be easily executed from a client device having a display device or an input device by connecting to the same network, special display on the server device can be performed. There is an effect that there is no need to incorporate a device or an input device or to temporarily connect a display device or an input device to a server device at the time of setting.
[0057]
Furthermore, when the client device collects the setting information of the server device to be initially set, for example, the machine name is set to be the same as the MAC address. Communication for confirming whether or not the setting has been made is unnecessary.
