The "ypcat passwd.byname" command failed to produce output to stdout. This could be the result of a NIS lookup failure, misconfigured NIS, or the lack of any user IDs in your NIS directory.
Run the "ypcat passwd.byname" command at a root prompt to check for errors. If this fails, verify that NIS is configured correctly and that the NIS server has user IDs configured in its directory.
