最近需要做一个实时统计网络情况并统计误包率的脚本,下面是StackExchange上的一个剽窃,虽然不完全满足,但只可以输出一些信息 #!/bin/bash host=$ if [ -z $host ]; then echo "Usage: `basename $0` [HOST]" exit fi while :; do result=` -c $host | grep 'bytes from '` ]; then echo -e "`date +'%Y/%m/%d %H:
[root@iZ94j7ahvuvZ sbin]# netstat -apn Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp /nginx tcp /sshd tcp /mysqld tcp ESTABLISHED /AliYunDun tcp ESTABLISHED /sshd ud
有时我们需要对app进行不同网络状况的测试,这时我们可以用到iPhone中的开发者功能进行测试. 按照下图所示打开网络调试功能: 可以看到系统默认配置的网络条件还是很多的,其中: 100%Loss是全丢包, 3G这个就不用说了吧 DSL是电话线上网, Edge是2G网络, High Latency DNS是高延迟, Very Bad Network是网络状况不稳定. 并且底部还有一个添加额外配置的选项可以自定义网络状况.
1. 介绍 Toxiproxy is a framework for simulating network conditions. It's made specifically to work in testing, CI and development environments, supporting deterministic tampering with connections, but with support for randomized chaos and customization
问: I'm a bit lost on AFNetorking's Reachability and haven't found a lot of good information out there. I have an app that logs into a web API. Each VC connects to the API in some way so each VC needs to have network access. I use a subclass of AFHTTP
