Figure 5-4 Flowchart 2. Security for telnet and ftp
NOTE: The corrections suggested in 2B1, 2C1, and 2F1 must be done by the superuser.
Also, except for the anonymous user ID, ftp requires non-null passwords on remote
user accounts.
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.
