Managing SNAplus2 Clients

Managing HP-UX Clients

before beginning or restarting the attempt to contact a server. If the client has lost contact with the server, SNAplus2 does not wait for the full timeout period, but retries after a random period between 5 seconds and the specified timeout; this is to avoid bursts of network traffic caused by large numbers of clients attempting to contact a server at the same time.

This parameter is optional; if it is not specified, the default is 200 seconds.

*

This line indicates that the client should attempt to contact a server running SNAplus2 by using a UDP broadcast message to all computers on its TCP/IP subnet (or on all subnets that it can access, if the client computer contains more than one LAN adapter card). The client retries the broadcast every 10 seconds, up to the number of attempts specified by the broadcast_attempt_count parameter, until it contacts a server. If the limit specified by broadcast_attempt_count is reached before a server has been contacted, the client then tries using directed messages to one or more named servers (specified by the following lines of the file).

In situations where the client cannot reach any servers using UDP broadcasts, do not include this line. This applies in the following cases:

•When the SNAplus2 LAN spans multiple TCP/IP subnets, and there are no SNAplus2 servers in any TCP/IP subnet that the client can access using UDP

•When UDP support is not installed on the client

In other cases, the use of UDP broadcasts is optional; to specify that broadcasts should not be attempted, do not include this line.

If this line is included, it must precede any server names in the file.
