It reads its information to do this from a bunch of Berkeley DB's, stored in files whose's names are derived from *dumpfilestem*, as produced by [*lr\_anonimize*(1)](/lr_anonimize/1.md). ## EXAMPLE A 'logfile' like e.g. ``` blaat fkrf 1.2.3.4.in-addr.arpa] pietje@bigcompany.com bla 1 2 3 lj;agas;gag blaat 1.2.3.4 fkrf 3.2.3.4.in-addr.arpa] bla 1 www.hotsex.com 2 3 lj;agas;gag jan@blaat.frut.com agagag blaat fkrf 4.2.3.4.in-addr.arpa] bla pietje@bigcompany.com www.hotsex.com 234.34.2.0 jan@blaat.frut.com 4.2.3.4.in-addr.arpa1 2 3 lj;agas;gag blaat fkrf tweede 3.2.3.4.in-addr.arpa] bla 1.2.3.4 1 blablabla.com 2 mdcc.cx 3 lj;agas;gag ``` wil get anonimized to ``` blaat fkrf 1.0.0.10.in-addr.arpa] john.doe.1@example.com bla 1 2 3 lj;agas;gag blaat 10.0.0.1 fkrf 2.0.0.10.in-addr.arpa] bla 1 1.example.com 2 3 lj;agas;gag john.doe.2@example.com agagag blaat fkrf 3.0.0.10.in-addr.arpa] bla john.doe.1@example.com 1.example.com 10.0.0.2 john.doe.2@example.com 3.0.0.10.in-addr.arpa1 2 3 lj;agas;gag blaat fkrf tweede 2.0.0.10.in-addr.arpa] bla 10.0.0.1 1 2.example.com 2 3.example.com 3 lj;agas;gag ``` The dump will look like ``` ip 234.34.2.0 10.0.0.2 ip 1.2.3.4 10.0.0.1 inaddr 3.2.3.4.in-addr.arpa 2.0.0.10.in-addr.arpa inaddr 1.2.3.4.in-addr.arpa 1.0.0.10.in-addr.arpa inaddr 4.2.3.4.in-addr.arpa 3.0.0.10.in-addr.arpa domain mdcc.cx 3.example.com domain blablabla.com 2.example.com domain www.hotsex.com 1.example.com email jan@blaat.frut.com john.doe.2@example.com email pietje@bigcompany.com john.doe.1@example.com ``` ## SEE ALSO [*lr\_anonimize*(1)](/lr_anonimize/1.md) ## VERSION $Id: lr\_deanonimize.in,v 1.7 2001/08/23 21:40:35 flacoste Exp $ ## COPYRIGHT Copyright (C) 2000-2001 Stichting LogReport Foundation LogReport@LogReport.org This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
