linux 最多能绑定255个IP，谁知道FreeBSD最多能绑定多少IP？对系统有什么影响？

我绑定过256个,/etc/netstart 时远程操作会死机.

我刚试了一下 加了500IP后 用/etc/netstart 启动没问题，正常。

可能楼上用的BSD版本老了。

FreeBSD_6_3

看样子应该是6.3吧，这样还算老？

hpunix

没错 我用的是 freebsd 6.3 release 版。怎么算是老版本呢

多起几次看看，我用6.2是5%的概率会死的。

为啥要绑这么多啊，看看都烦

用 arp 发布不行么？

mirnshi

在4.x上测试过4个C的，没啥问题。
