IP address validation
When a TCP/IP connection is established,
netman reads the requester's node name and IP address from the
socket. The IP address and node name are used to search the Symphony file
for a known IBM Workload Scheduler workstation
with one of the following possible results:
- If an IP address match is found the validation is considered successful.
- If a node name match is found, the validation is considered successful.
- If no match is found in the Symphony file or the IP address returned does not match the one read from the socket, the validation is considered unsuccessful.
The local
option, nm ipvalidate, determines the action to be
taken if IP validation is unsuccessful. If the option is set to full,
unsuccessful validation causes IBM Workload Scheduler to
close the connection and generate an error message. If the option
is set to none (default), IBM Workload Scheduler permits
all connections, but generates a warning message for unsuccessful
validation checks.
