跟手动填一样的效果
还是感谢

这是我macbook的ifconfig情况：
en0: flags=8863 mtu 1500
inet6 fe80::21b:63ff:fe1c:c1c4%en0 prefixlen 64 scopeid 0x4

发帖数: 123 | 3 It's actually pretty much the same, only that you don't encrypt the entire
GRE tunnel in crypto acl, GRE only used as a carrier for IPsec traffic.
Configure ipsec security protocol, define esp or ah or both. Define
interesting traffic in crypto acl. Create gre tunnel, allow routing protocol
or static pass through between ipsec peers.
however, mcast/bcast along with routing protocols are only wrapped by gre,
and interesting(protected) traffic are wrapped by esp and gre. |

发帖数: 9308 | 4 直接用IP，除了修改client.ovpn这个文件中的地址，没别的地方需要改了吧。
修改后，客户端访问VPN，还是联不通，log文件除了没有下面这行，其他跟原来显示的
都一样
read UDPv4: Connection reset by peer (WSAECONNRESET) (code=10054)
看了一下server端的状态，好像不对

InetAddress.getLocalHost() does not work.
InetAddress.getLocalHost().getHostAddress() return "127.0.1.1"
while the actual ip is 192.168.21.62.

发帖数: 292 | 7 Ubuntu 8.04, 现在蹲在地下室，总算把无限网卡搞定了，能上网，可是看不到局域网
的邻居。
DHCP得到的IP是 192.168.1.104，能上网，但是无法访问192.168.1.1（路由器），
ping的结果是Destination Host Unreachable。同样，在局域网内部其他电脑也不能访
问这台电脑share出来的东西。
只要拉一根网线顺楼梯走下来，就一切都好，所以说samba配置没有问题的。
而且我特地把路由器关掉，跑过来看，果然没有网络了，所以我所连的肯定是自己家的
路由器，不是邻居的。

发帖数: 273 | 12 mynode 是 node的identifier
numprocs 是node的总数.
在开始的串行程序中, loop按照i循环 100次
现在我想把loop循环简单的分拆开来. 但是有个balance的问题. 如果 node 数目不能
被100整除, 就会出问题.
循环中的barrier 还是要的. 每次循环主节点要读一些数据,然后bcast给所有的nodes.
但是好像和循环外面的barrier冲突了,成了deadlock了. 不知道这种情况怎么解决.
多谢拉
