What command is used to test network connectivity between two hosts?

Answer 1

PING
The "ping" command does. It sends out an ICMP echo request message and waits for a reply. However, network administrators sometimes block the ICMP protocol. In that case, accessing a service on the remote computer (e.g. opening a Web page on a Web server) would do if the service is currently available and is not blocked.
Testing connectivity between computers highly relies on networking protocols they use. Assuming it's TCP/IP (as the most widespread communication protocol used nowadays), the command to test reachability is 'ping'. To use it, you have to know IP address (which consists of 4 groups of digits separated with dots, like 10.4.199.15) or a hostname (like, remote.my.domain) of the remote computer. Launch shell interpteter and issue one the following:

ping 10.5.199.15

ping other.my.domain

depending on information on a remote device available to you.

After issuing one of these commands, expect to see at least one of the following:

ping: unknown host reemote.my.domain

(in case you've mistyped a hostname)

PING 10.6.199.15 (10.6.199.15) 56(84) bytes of data.

^C

--- 10.6.199.15 ping statistics ---

2 packets transmitted, 0 received, 100% packet loss, time 7012ms

(in case you've mistyped its IP address or there's some software installed blocking incoming pings)

PING remote.my.domain (10.5.199.15) 56(84) bytes of data.

64 bytes from remote.my.domain: icmp_seq=2 ttl=254 time=0.727 ms

64 bytes from remote.my.domain: icmp_seq=2 ttl=254 time=0.727 ms

64 bytes from remote.my.domain: icmp_seq=2 ttl=254 time=0.727 ms

^C

--- remote.my.domain ping statistics ---

3 packets transmitted, 3 received, 0% packet loss, time 1003ms

(in case the link between two systems is functioning properly)

Answer 2

step 1. Determine IP address of the computer you want to confirm connectivity with by: A. Open command prompt (on windows pc, start then click,run. Type cmd into the open box. B. at the command prompt, type ipconfig record the IP address. 2. From the other computer, open the command prompt as directed above, then type in ping Ian's then the IP address. Example, if the IP address of the computer above is 192.168.1.101, you would type this: ping 192.168.1.101. Then hit enter. If you see replies, you have confirmed connectivity. If the request times out, then you have a problem that requires further investigation.

Answer 3

The "ping <address>" command, where <address> is either the domain name or IP address of the remote computer.

Answer 4

the very basic test that you can do is ping test. ping the other host from one end and if you get a response then there is connection between the two.

Answer 5

Ping is typically used.

Answer 6

Ping -t
