安装完vpn，运行的时候总是提示错误。
连接不到vpn的服务器。

错误代码如下：

$ vpnclient connect inside-nus
Cisco Systems VPN Client Version 3.7(Rel)
Copyright (C) 1998-20002 Cisco Systems, Inc. All Rights Reserved.
Client Type(s): Linux
Running on: Linux 2.4.20-8 #1 Thu Mar 13 17:54:28 EST 2003 i686

Incorrectly built binary which accesses errno, h_errno or _res directly. Need to be fixed.
Initializing the IPSec Link.

Contacting the gateway at 137.132.3.176...(backup)
Contacting the gateway at 137.132.3.177...(backup)
Remote peer is no longer responding.


Ping自己电脑，得到如下结果
$ ping localhost
64 bytes from localhost.localdomain(127.0.0.1): ....
64 bytes from localhost.localdomain(127.0.0.1): ....

安装没有任何问题，不过在run下面脚本的时候，有警告提示
$ ./vpnclient_init start
Starting /usr/local/bin/vpnclient: Warning: loading /lib/modules/2.4.20-8/CiscoVPN/cisco_ipsec will taint the kernel: no license.
Module cisco_ipsec loaded, with warnings.
Done.



请高手指点下。。不胜感激！
