Troubleshooting the Internet Services
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 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? There are additional security
files that 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? Are you attempting to use ftp? If you are,
go to 2C3; otherwise, go to 2F.
2C3. Access to ftp? If the user you are logging in 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.
2C5. Fix $HOME/.netrc. If the file is incorrect, make
corrections to it and go to 2C6.
2C6. Once the corrections are made, repeat this flowchart
beginning with 2A.
2D. See node manager. If your system was denied access to
the server system by the /var/adm/inetd.sec file,
but you wish to use the server, contact the node
manager of the server system and request access.
