2A. Determine the number of existing connections.If inetd
was started with the -l option, the system log may list
the number of connections. If these messages do not
appear in the system log, continue with 2B, or enable
the connection logging with inetd -l.
2B. Maximum number of connections? The maximum
number of simultaneous connections is specified in the
optional file /var/adm/inetd.sec. When inetd is
configured, it checks this file to determine the number
of allowable incoming connections. Look at this file to
determine how many connections are allowed. The
default is 1000.
2B1. See the node manager. If the maximum number of
connections has been reached, the node manager can
change this value in the /var/adm/inetd.sec file.
2C. Access to the server? The /var/adm/inetd.sec file
also contains a list of systems that may not access the
server. If inetd was started with the -l option, the
system log may list the connections that are refused
access to the server. Check this log file, if it exists, or
ask the node manager to verify whether you have
access to the server. If you find that you do not have
access to the server, continue with 2D.
2C1. Using telnet or ftp? Additional security files exist for
these services that must be checked. If you are using
ftp or telnet go to 2C2; otherwise, go to 2E.
2C2. Using ftp? If you are attempting to use ftp, go to 2C3;
otherwise, go to 2F.
2C3. Access to ftp? If the user you are logging on as is listed
in the /etc/ftpusers file on the server system, you
may not use ftp to that system. If you do not have
access to ftp, go to 2G.
2C4. $HOME/.netrc file incorrect or non-existent? If this file
is incorrect or non-existent, it is not used for the
connection attempt. In particular, if the file exists,
check its mode bits, owner ID, and syntax. Type man 4
netrc for more information. If it is correct, go to 2H.
