Пытаюсь создать скрипт, чтобы выдавал сообщение юзерям, которые заходят через Samba.

MESSAGE="test"
    for i in `smbstatus | grep '(\w\+\.\w\+\.\w\+\.\w\+)' `; do
        echo $i | read SHARE USER GROUP MACHINE IP JUNK
        echo $MESSAGE | smbclient -M $MACHINE -I $IP
    done
выдаёт ошибку

Connection to -I failed. Error NT_STATUS_BAD_NETWORK_NAME

конфиг, как в мануалах

# Samba config file created using SWAT
