LDM 6.8 Release Notes

• Installation:
  • The ldmadmin(1) configuration-file is copied, read, and rewritten with additional user-configurable parameters.
• LDM Server (rpc.ldmd):
  • Improved vetting (i.e., access-checking) of a client to prevent delays due to a time-out on the reverse DNS lookup, which is used to convert the client IP address into a hostname:
    • Moved vetting from the LDM server before fork(2)ing a child process to the fork(2)ed child process.
    • Made vetting a two-phase procedure: first with the client IP address and then, if and only if that fails, with the client hostname.
  • Added the new option "-M max_clients" (default: 256).
• ldmadmin(1):
  • Program:
    • Added the ability to check the accuracy of the system clock. This new ability is highly user-configurable. The defaults are to check the clock but not to abort if it's off by too much.
    • Added removal of product-information (~/.*.info) files to the "delqueue" command if "$deleteInfoFiles" is true in the ldmadmin(1) configuration-file.
    • Added the new option "-M max_clients".
    • Added the new commands "printmetrics", "addmetrics", and "plotmetrics".
    • Moved variables "$os" and "$release" to the configuration-file.
    • Added the error message "Uknown command: ".
    • Removed printing of "ldmadmin" from "ldmadmin usage" output.
  • Configuration-file (ldmadmin-pl.conf):
    • Improved internal documentation and layout.
    • Added many new variables.
  • Manual-Page:
    • Documented LDM configuration-file argument.
    • Added "-C" and "-x" options.
    • Rearranged options alphabetically.
  • scour(1): Added the prefix "scour: " to log messages.
  • scripts/plotMetrics: Created this script for plotting the accumulated output of "ldmadmin addmetrics".
