nginx开了80和88端口,80不能访问,88可以访问,求助下
突然出现的奇怪问题,80的http服务不能访问,过一阵正常,过一阵又不能访问,22端口等别的端口都正常访问,所以在nginx上开了个88端口.
求助下,下面的tcpdump的信息
用一台服务器wget http://162.243.113.211, 一直在等待,用tcpdump看看
tcpdump port 80 and src 212.50.88.6
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes

然后wget http://162.243.113.211:88, 正常,用tcpdump看看
