Step 5: Create a configuration file (conf.rfw)
Therfw‐updateutilityusesaconfigurationtextfiletospecifywhichmodulesshouldbe
updatedandwhethertheywillbeupdatedinparallelwithothermodulestosavetime.The
textfilecanbeanyname,butitisnamedconf.rfwinthisdocument.
Theconf.rfwfilecontainsalistofbundleswithURLpathsandalistofupdatetargetswith
Telnetconnectstrings.TheupdatetargetconnectstringcontainstheIPaddressand,if
needed,logininformationtoallowaconnectionfromthehosttotheupdatetarg et.All
updatetargetsmustbeaccessiblefromthehostrunningrfw‐update.
Theconf.rfwconfigurationfilealsoidentifiesthelocationsoftheupdatebundles.Thebundles
intheconf.rfwfile mustcontainvalidURLpathsfromeachtargettoupdatebundles
somewhereonthesystem(notnecessarilyonthehost).

butthebundlesmustbeaccessiblefromtheupdatetargetusingthespecifiedURL.TheIP
