FreeSwan 2.0

Pessoal

Eu estou tentando montar uma VPN com FreeSwan 2.0 e esta dando a mensagem abaixo quando xecutu o #ipsec verify

Opportunistic Encryption DNS checks:
Looking for TXT in forward map: filiao1 [MISSING]
Cannot execute command "host -t txt filiao1": No such file or directory
Does the machine have at least one non-private address? [FAILED]
[root@filiao1 squid]# Cannot execute command "host -t txt filiao1": No such file or directory
-bash: Cannot: command not found
[root@filiao1 squid]# Looking for TXT in forward map:Does the machine have at least one non-private address?


Eu ja dei uma pesquisada no google e nao encontri nada sobre isto.

Alguem pode me dar um Help??????
