It is therefore our motivation to continue our goal to offer an easy compensation model for creators and supporters alike. Looking at the past months, things turn out to be quite successfull regarding the growth of the platform. Next time you have connectivity issues, let ping be the first tool you turn to. News from the development team by OpenDesktop Team | News – An overview site part of for all Creatives The ping command is simple, but it can be eyes and ears out on the vast expanse that is your network. ![]() You can find more information for gping on Github. There's even a GUI for ping: Gping is available for Linux, macOS, and Windows. The iputils package provides a ping command, Busybox has a ping command, and there's one from BSD and others. You can also stop pinging after some value of time (in seconds) with the -w option: $ ping -w 6 Variants This changes the ping interval to two seconds: $ ping -i 2 You can change the time interval between pings using the -i option. This provides the UNIX epoch time, plus microseconds: $ ping -D 8.8.8.8 You can print a timestamp before each ping report in your terminal with the -D option. This command sends 43 bytes: $ ping -s 35 -c 5 8.8.8.8 The default packet size is 56, which translates into 64 ICMP data bytes when combined with the 8-byte header. You can change the size of the ICMP packets you're sending with the -s option. Using only one of them explicitly can be enforced by specifying -4 or -6. This at least tells you whether the host is down or whether it's just a web server issue.įor example, say you're trying unsuccessfully to reach. When a site has apparently disappeared, you might be able to probe the worldwide DNS network to find out what its host server's address is, and then ping that server. ![]() Google's DNS server is relatively easy to remember, and it does respond to pings: $ ping -c 2 8.8.8.8 However, there are some that do, and a vital server to the working of the Internet is a nameserver. Again, not all servers are permitted to receive, much less respond to, ICMP. For instance, I can ping my printer: $ ping 192.168.0.4 Pinging beyond your networkīeyond establishing that your own network is working as expected, you can also ping out into the wider world beyond your router. Not all are guaranteed to respond (some devices drop ICMP packets), but many do. What about other hosts on my network? You can ping all kinds of devices. If you can reach your router, that means your wired or wireless connection is working. When you don't specify how many pings to send, you can stop ping from running with Ctrl+ C. The exact IP address depends on your router's configuration. The address of a router usually starts with 192,168, or 10. Rtt min/avg/max/mdev = 0.069/0.069/0.069/0.000 msĪfter you've established that your local networking stack is up and running, you can ping your router. $ ping 0 -c1Ħ4 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.069 msġ packets transmitted, 1 received, 0% packet loss, time 0ms You can control how many signals you send with the -c (as in count) option. The ping command understands the localhost hostname, its IP address, and a shortcut of just 0. The computer you're operating is also called your localhost, and it has a special IP address assigned for speaking to itself: 12.0.0.1. When in doubt, first ping your own computer to ensure you're running a networking stack. ICMP is, by design, a rudimentary format used mostly for diagnostics: It's essentially a call and response signal.īut there's an order to troubleshooting, and it starts as close to home as possible. A ping sends an Internet Control Message Protocol (ICMP) packet to a destination IP address. When you can't reach a computer on your local network, or a server on the Internet, you can ping it. ![]() Free online course: RHEL Technical Overview. ![]()
