Installing, Configuring and Administering the Kerberos Server V 2.0 on HP-UX 11i

Propagation

Chapter 7 219
NOTE Intervals less than 15s could generate too much
network traffic during peak authentication times.
key_exp=n[s|m|h|d] Specifies the length of time a session key is valid,
where n, indicates the number of seconds, minutes,
hours, or days.
The default is value six hours (6h). The default unit is
hours.
max_cache=n[K|M] Specifies the maximum size that each security
server’s cache file (prop_hostname) can reach before it
is deleted, where n, indicates the number of bytes,
kilobytes, or megabytes. A deleted cache file instigates
a full database propagation when the connection is
re-established.
The default value is 1024K. The default unit is bytes.
max_retry_delay=n[s|m|h|d] When kpropd attempts to establish a
connection with a secondary server and the attempt
fails, kpropd waits for a period of time called the retry
delay, initially set for one minute. With each
subsequent time out, the retry delay doubles. The
max_retry_delay then, is the maximum interval
between retries that kpropd should wait before it
terminates its attempt to establish a connection with a
secondary server and log the failure to the system log.
net_timeout=n[s|m|h|d] Specifies the length of time the propagation
system waits for a response from any security server
before terminating the connection, where n, indicates
the number of seconds, minutes, hours,or days.When a
timeout occurs, all propagating records are cached into
the prop_hostname file associated with the target
server; when a connection to the server is
re-established, records in the cache file are then
propagated.
The default value is 30 seconds (30s). The default unit
is seconds.
