Aliases Not Checked
When SWCC Agents scan the Client authorization list, they do not check
aliases. The entry in the Client authorization list must match that returned by a
gethostbyaddr call in the hostent h_name field. SWCC will not scan the
hostent alias list to check if an alias may match the Client authorization list.
Client System Not on Agent’s List
The client system may not on the authorized client system list for the Agent.
Entry in the Client Authorization List Does Not
Match
Generally, the entry in the Client authorization list for an Agent must match
what gethostbyaddr(<client IP address>) will return in the hostent h_name
field when gethostbyaddr(<client IP address>) is executed on the Agent
system. If hosts files are not exactly the same on all systems, the h_name
returned may vary on different Agent systems. For example,
xxx.xxx.xxx.xxx client.somewhere.com client
will return client.somewhere.com in the h_name field, but
xxx.xxx.xxx.xxx client client.somewhere.com
will return client in the h_name field.
In some situations, you can configure the way a system uses DNS and its local
hosts file. Please refer to your system documentation to find how your system
is configured. Some systems may be configured to do the following:
■ Check its local hosts file first, then go to DNS.
■ Go to DNS first, then check its local hosts file.
■ Ignore DNS even if configured.
■ Ignore the local hosts file.
The best way to verify what needs to be used for a Client name in the Client
authorization list is to write a program that runs on the agent system and prints
the h_name field returned by gethostbyaddr(<client IP address>). Remember,
the dynamic IP address allocation is not supported.
