5. JPNIC information services Japanese Page

JPNIC offers services with the help of the resources (JPNIC database, other open documents/files) that JPNIC has through the network. It is also planning to arrange and prepare network information, information related to Japan, and provide pointers for achieving information from other organizations.

In order to achieve the target, JPNIC has formed the Information Service Working Group (IS-WG) from this year. Although there are plans for increasing information, strengthening operations, there are still several factors that depend on volunteers. JPNIC will full-heartedly welcome comments on how to enrich its services. So if there is anyone who would like to help JPNIC with data or other services, then the person is requested to send an e-mail to is-wg@nic.ad.jp.

If an e-mail with the following command is send to mail-server@nic.ad.jp then the requested file or search status will be returned to the sender (defined by From: or Reply-to: field) of the e-mail. In case of a large file (more than 50k bytes) the file will be send part by part.

        Commands

           send help       This document will be send
           send index      List of files
           send filename   Send the file defined by filename

Commands should be written from the first line of the body of the e-mail. There should be one command on each line and the command end should be written in the last line to mean that there are no more commands. For example, this document and the list of files can be retrieved by executing the following.

           % mail mail-server@nic.ad.jp
           Subject:

           send index
           end
           .
           %
            

In case of PC networks, as the number of e-mails, amount of data that can be stored in the mailbox depends on the network system, please check the details before using this service.

Service that can be availed through the machines that have direct Internet connectivity.

This service can be used to retrieve information about a person who is involved in network projects. The related information about the key-word can be retrieved by executing the following command.

          whois -h whois.nic.ad.jp key-word
            

The help regarding how to use whois can be obtained in Japanese by executing whois -h whois.nic.ad.jp help. The English version can be obtained by executing the command in the following way.

          whois -h whois.nic.ad.jp key-word/e
            

Note: There should not be any space between the key-word and the /. In case of using * or other symbols, the key-word should be double couted.

5.2.2.2 Use of anonymous ftp:

Files stored in ftp.nic.ad.jp can be obtained by using this service.

If the command ftp ftp.nic.ad.jp is executed, the user will be asked for user id and password. In that case files can be accessed, by specifying anonymous for user id and e-mail address for password. An example for anonymous ftp is given below. IP address (192.41.192.1) can also be used. Care should be taken, for this IP address may be changed in future.

         % ftp ftp.nic.ad.jp
         Connected to ns.nic.ad.jp.
         Name (ftp.nic.ad.jp:tatsumi): anonymous  <- specify user id as
                                                     anonymous
         331 Guest login ok, send ident as password.
         Password:                                <- key-in complete
                                                     e-mail address
         230 Guest login ok, access restrictions apply.
         ftp>                                     <- ftp commands can be used.

                                                     be found by executing ?.
            

The necessary files can be accessed with the help of the commands "ls" and "get". List of files/directories can be displayed by executing "ls". As the file ls-lR contains the list of files under the directory pub, it may be convenient to get this file first. An example is given below.

          ftp> ls
          bin
          dev
          etc
          lost+found
          ls-lR
          pub
          src
          usr
          ftp> get ls-lR
