vstpd armazenando mac ou ip da rede em cache

Galera.

Tentei localizar no site e não consegui.

Aqui na empresa temos o fedora como server de ftp usando o vsftpd

ele está armazenando ou mac address das plçaca ou o ip da rede onde o usuario entra com a senha uma única vez e depois não precisa mais inserir a mesma.

o pode estar acontecendo?

Segue abaixo o vstpd.conf

segue agora sim com tudo no seu devido lugar "Eu Acho...'
