9.6 Status of services provided by JPNIC

The number of access to mail-server, Anonymous FTP and Gopher for the year 94' was 1000, 30,000 and 28,000 respectively. In contrast to that as can be seen in the table given below, the number of access to WWW and FTP is on a rapid increase. However, the number of access to Gopher and access from foreign countries have not increased. Although the number of access to FTP includes the accesses following the links of the WWW server, if the recent boost in the number of users of the Internet is considered, then the rise in the number access to the JPNIC Anonymous FTP is trivial. However, it has been found that a certain kind of FTP clients end up connection with the server in an incomplete state, thus causing the server to wait infinitely with the accept() system call. This might have been the cause for which the number of access to the FTP server is low. The problem has been technically investigated and at present the problem is almost solved by adding the alarm() system call. In this case if the process forked by inetd does not end even after 60 seconds then the data connection will be automatically terminated. Although it can not be said that the present solution is complete, it is largely hoped that it will be able cope with the present situation.

Due to lack of time, the access statistics of mail-server could not be prepared for the year '95. The total number of mail, request for file and whois access during '93/3 was 1841, 2001 and 3246 respectively and it is distinctly discernible that the number of access to whois DB through mail-server is remarkably high. The guideline given in the documents of DB registration includes both the use of whois and the use of whois through mail-server. This might be the cause which has influenced the number of access to whois DB to be so high.
