|

| 207 | will not continually notify you that files you intentionally changed are
|
---|
| 208 | a security violation. To do this you must first <command>ls -l

| 209 | /var/lib/tripwire/report/</command> and note the name of the newest file
|
---|
| 210 | which starts with <filename>linux-</filename> and ends in

| 211 | <filename>.twr</filename>. This encrypted file was created during the

---|
| 212 | last report creation and is needed to update the

---|
[0bc6cf76] | 213 | <application>Tripwire</application> database of your system. Then, as the

---|
| 214 | <systemitem class='username'>root</systemitem> user, type
|
---|
[1503942] | 215 | in the following command making the appropriate substitutions for

|

|
---|
| 224 | will be updated. If there are files which you still want to be warned
