问题 Scripting and want to ping devices on a network, tell me if it's reachable or not, and then get the ttl data from the ping and tell me the operating system. Ive tried using the awk command, but I am also new to scripting and may not be using it correctly. for host in $(seq 1 255); do ping -c 1 $sn.$host | grep "Unreachable" &>/dev/null if [ $? -eq 0 ]; then printf "%s\n" "$sn.$host is Offline" fi ping -c 1 $sn.$host | grep "ttl" &>/dev/null if [ $? -eq 0 ]; then printf "%s\n" "$sn.$host is

How to perform a ping-test programmatically on Windows?

问题 I'd like to make an IP-test in a C command line program on Windows . Now I'm using the cmd-command in my program with something like this: if(system("ping -c1 8.8.8.8 -w 2 ") == 0){ printf("request successful\n"); return true; }else{ printf("request not successful\n"); return false; } Please note that the code above is just an example: with my program I will try to ping some devices, to see if they are online; if not I know there is a connection issue. Since I need only the connection status

using ping in infinite loop

问题 I want to check the instrument connectivity, continuously. These instruments are connected by LAN. I ping them in an infinite loop. After a few seconds, I'm met with a blue screen and the system restarts. private async void checkingDevice() { await Task.Run(() => { do { Panel selectedPanel; multicastPing.send(); foreach (var device in (Device[])Enum.GetValues(typeof(Device))) { selectedPanel = (Panel)this.Controls.Find((device).ToString(), true)[0]; if (multicastPing.check(device.ToString()))

Using Ping in Parallel in a Bash Script

由 ≯℡__Kan透↙ 提交于 2020-06-10 06:44:16
问题 So I'm trying to ping a range of addresses in parallel in a bash script, count the ones that are alive, and print them out. The script works to ping the addresses and print the live ones out but it always outputs: "There were 0 online hosts and 254 offline hosts" It's not incrementing the ALIVE variable in my code, maybe because it's in a subshell? How could I get around this? Here's what I have right now: #!/bin/bash TOTAL=0 ALIVE=0 if [ $# -eq 3 ] then echo -n 'Live hosts:' for ((i = $2; i
