[FUG-BR] Erros após modificar sysctl.conf

[MArvelrat]

Olá pessoal
tenho um dúvida...
após ter feito algumas mudanças em rc.conf e sysctl.conf começei a notar 
mensagens estranhas na saída do messages e também do log do squid 
cache.log...segue abaixo o que foi mudado e as saídas...
Existem outras saídas novas ..porém estas identifiquei...é o log de 
tentativas de conexao em portas fechadas...mas estas aí procurei no 
google e nao acheoi nada concreto

*rc.conf*
syslogd_flags="-ss"
rpcbind_enable="NO"
kern_securelevel_enable="YES"
kern_securelevel=1netd_enabln="NO"

nfs_client_enable="NO"
