询问关于在Red Hat 9.0下安装vpn的问题安装完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.

it's most likely due to you have turned on the firewall under RH.turn it off by going to system administration tools and it should work.
one of the error message regarding h_errno access happens due to a kernel update. I heard it will be fixed by later release from RH. [likia! (1-14 9:17, Long long ago)] [ 传统版 | sForum ][登录后回复]2楼
