我刚刚获得了一个具有 root 访问权限的虚拟服务器(我认为是 virtuozzo)。我想安装 shorewall,但是当我想启动它时,我收到错误消息
# shorewall start
Compiling...
Processing /etc/shorewall/shorewall.conf...
ERROR: Your kernel/iptables do not include state match support. No version of Shorewall will run on this system

所以现在我想知道我能做什么?系统是 ubuntu 11.10。
我在 Google 计算引擎上有两台机器,我想通过 ssh 连接另一台服务器。因此,在第一台机器(namenode)上,我为用户 hadoop 创建了一个无密码的 ssh 密钥,并做了一个 cat id_rsa.pub >>authorized_keys。在第二台机器(datanode1)上还有一个叫 hadoop 的用户。第二台机器的 hadoop 用户有一个空的 ~/.ssh 目录。
当我现在尝试从第一台机器 ssh 到第二台机器时,我得到:
hadoop@namenode:~/.ssh$ ssh -v hadoop@datanode1
