D_hostip_beg=1

D_hostip_end=254

Echo-n "input the hostip (default $d_hostip_beg $d_hostip_end):"

Read hostip_beg hostip_end

: ${hostip_beg:=$d_hostip_beg}

: ${hostip_end:=$d_hostip_end}

Echo "hostip_beg:$hostip_beg"

Echo "hostip_end:$hostip_end"

If [$hostip_beg-gt $hostip_end]; then

Echo "$hostip_beg greater than $hostip endurance requests!"

Exit 0

Fi

: > pinglog

: > pingerrlog

Ping_count=3

For ((hostip=$hostip_beg;hostip/dev/null

If [$? = 0]; then
