>Sommario
>    SELinux ha impedito l'accesso a /var/log/wicd.log da parte di /sbin/ifconfig
>    "write".
>
>Descrizione dettagliata
>    SELinux is preventing /sbin/ifconfig (ifconfig_t) "write" to
>    /var/log/wicd.log (var_log_t). The SELinux type var_log_t, is a generic type
>    for all files in the directory and very few processes (SELinux Domains) are
>    allowed to write to this SELinux type.  This type of denial usual indicates
>    a mislabeled file.  By default a file created in a directory has the gets
>    the context of the parent directory, but SELinux policy has rules about the
>    creation of directories, that say if a process running in one SELinux Domain
>    (D1) creates a file in a directory with a particular SELinux File Context
>    (F1) the file gets a different File Context (F2).  The policy usually allows
>    the SELinux Domain (D1) the ability to write, unlink, and append on (F2).
>    But if for some reason a file (/var/log/wicd.log) was created with the wrong
>    context, this domain will be denied.  The usual solution to this problem is
>    to reset the file context on the target file, restorecon -v
>    /var/log/wicd.log.  If the file context does not change from var_log_t, then
>    this is probably a bug in policy.  Please file a
>    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against the selinux-policy
>    package. If it does change, you can try your application again to see if it
>    works.  The file context could have been mislabeled by editing the file or
>    moving the file from a different directory, if the file keeps getting
>    mislabeled, check the init scripts to see if they are doing something to
>    mislabel the file.

>Abilitazione accesso in corso
>    Potete cercare di correggere il contesto del file, eseguendo restorecon -v
>    /var/log/wicd.log

>    Il seguente comando abiliterÃ  questo tipo d'accesso:
>    restorecon /var/log/wicd.log
