This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise. |

By 1996/12/04, the utmp element size has been changed, in order to allow for longer usernames. This change renders all existing wtmp files unusable. The cvt-wtmp utility is provided as an aid to convert your old wtmp files into the new format, so you don't lose the existing track record. The tool cannot handle gzip'ed wtmp backups, so unzip them first if you need. Then simply call it as: ./cvt-tmp /var/log/wtmp* The old wtmp files are being renamed to <file>.bak, so nothing will be lost even in case of a failure. If you are only about to test whether the tool will grok your files correctly, you can run it as: ./cvs-tmp -n /var/log/wtmp* The tool tries an ``educated guess'', based on the reasonability of the timestamp values in the wtmp file. If it fails to recognize the format of your wtmp, it normally bails out, or at least ignores garbage records. In this case, rename the .bak files to the original name, and try to force the conversion: ./cvs-tmp -f /var/log/wtmp.xxx Make sure to verify the result however!
