caucy / batch_ping Goto Github PK

使用batch ping 出现接收的包数大于发出的包数，因为在一个进程中同时进行了多次ping的动作

run err socket: The requested protocol has not been configured into the system, or no implementation for it exists.

在我的机器上实测当IP超出50个会panic，后来尝试将IP分成若干个小于50条的切片依次调用，只有第一次能执行成功，之后就一直是“it is time to exit”，请问如何解决

pid is stored as int but gets converted to uint16 and thus will never match when processPacket compares int on batchpinger to uint16 from packet

// Pinger.SendICMP

xid := p.id & 0xffff
body := &icmp.Echo{
    ID:   xid,
    Seq:  seqID,
    Data: t,
}

// BatchPinger.processPacket

xid :=  p.id & 0xffff
if pkt.ID != xid {
...
}

source:, network:ip
ip 192.168.8.110, sended
ip 192.168.8.120, sended
not the process id
panic: runtime error: invalid memory address or nil pointer dereference
