EasyPing 2.3 – Ping client to determine host accessibility. August 26, 2017 EasyPing is a network scanning tool for Mac users to test whether a particular host is accessible across an IP network.
- DESCRIPTION
Net::Ping - check a remote host for reachability
This module contains methods to test the reachability of remote hosts on a network. A ping object is first created with optional parameters, a variable number of hosts may be pinged multiple times and then the connection is closed.
You may choose one of six different protocols to use for the ping. The 'tcp' protocol is the default. Note that a live remote host may still fail to be pingable by one or more of these protocols. For example, www.microsoft.com is generally alive but not 'icmp' pingable.
With the 'tcp' protocol the ping() method attempts to establish a connection to the remote host's echo port. If the connection is successfully established, the remote host is considered reachable. No data is actually echoed. This protocol does not require any special privileges but has higher overhead than the 'udp' and 'icmp' protocols.
Specifying the 'udp' protocol causes the ping() method to send a udp packet to the remote host's echo port. If the echoed packet is received from the remote host and the received packet contains the same data as the packet that was sent, the remote host is considered reachable. This protocol does not require any special privileges. It should be borne in mind that, for a udp ping, a host will be reported as unreachable if it is not running the appropriate echo service. For Unix-like systems see inetd(8) for more information.
Easyping 2 5 – Ping Client To Determine Host Accessibility Tool
If the 'icmp' protocol is specified, the ping() method sends an icmp echo message to the remote host, which is what the UNIX ping program does. If the echoed message is received from the remote host and the echoed information is correct, the remote host is considered reachable. Specifying the 'icmp' protocol requires that the program be run as root or that the program be setuid to root.
If the 'external' protocol is specified, the ping() method attempts to use the
Net::Ping::External
module to ping the remote host. Net::Ping::External
interfaces with your system's default ping
utility to perform the ping, and generally produces relatively accurate results. If Net::Ping::External
if not installed on your system, specifying the 'external' protocol will result in an error.If the 'syn' protocol is specified, the 'ping' method will only send a TCP SYN packet to the remote host then immediately return. If the syn packet was sent successfully, it will return a true value, otherwise it will return false. NOTE: Unlike the other protocols, the return value does NOT determine if the remote host is alive or not since the full TCP three-way handshake may not have completed yet. The remote host is only considered reachable if it receives a TCP ACK within the timeout specified. To begin waiting for the ACK packets, use the 'ack' method as explained below. Use the 'syn' protocol instead the 'tcp' protocol to determine reachability of multiple destinations simultaneously by sending parallel TCP SYN packets. It will not block while testing each remote host. This protocol does not require any special privileges.
Functions
Create a new ping object. All of the parameters are optional and can be passed as hash ref. All options besides the first 7 must be passed as hash ref.
proto
specifies the protocol to use when doing a ping. The current choices are 'tcp', 'udp', 'icmp', 'icmpv6', 'stream', 'syn', or 'external'. The default is 'tcp'.If a
timeout
in seconds is provided, it is used when a timeout is not given to the ping() method (below). The timeout must be greater than 0 and the default, if not specified, is 5 seconds.If the number of data bytes (
bytes
) is given, that many data bytes are included in the ping packet sent to the remote host. The number of data bytes is ignored if the protocol is 'tcp'. The minimum (and default) number of data bytes is 1 if the protocol is 'udp' and 0 otherwise. The maximum number of data bytes that can be specified is 65535, but staying below the MTU (1472 bytes for ICMP) is recommended. Many small devices cannot deal with fragmented ICMP packets.If
device
is given, this device is used to bind the source endpoint before sending the ping packet. I believe this only works with superuser privileges and with udp and icmp protocols at this time.If <tos> is given, this ToS is configured into the socket.
For icmp,
ttl
can be specified to set the TTL of the outgoing packet.Valid
family
values for IPv4:Valid
family
values for IPv6:The
host
argument implicitly specifies the family if the family argument is not given.The
port
argument is only valid for a udp, tcp or stream ping, and will not do what you think it does. ping returns true when we get a 'Connection refused'! The default is the echo port.The
bind
argument specifies the local_addr to bind to. By specifying a bind argument you don't need the bind method.The
gateway
argument is only valid for IPv6, and requires a IPv6 address.The
retrans
argument the exponential backoff rate, default 1.2. It matches the $def_factor global.The
dontfrag
argument sets the IP_DONTFRAG bit, but note that IP_DONTFRAG is not yet defined by Socket, and not available on many systems. Then it is ignored. On linux it also sets IP_MTU_DISCOVER to IP_PMTUDISC_DO but need we don't chunk oversized packets. You need to set $data_size manually.Ping the remote host and wait for a response. $host can be either the hostname or the IP number of the remote host. The optional timeout must be greater than 0 seconds and defaults to whatever was specified when the ping object was created. Returns a success flag. If the hostname cannot be found or there is a problem with the IP number, the success flag returned will be undef. Otherwise, the success flag will be 1 if the host is reachable and 0 if it is not. For most practical purposes, undef and 0 and can be treated as the same case. In array context, the elapsed time as well as the string form of the ip the host resolved to are also returned. The elapsed time value will be a float, as returned by the Time::HiRes::time() function, if hires() has been previously called, otherwise it is returned as an integer.
Allows source endpoint verification to be enabled or disabled. This is useful for those remote destinations with multiples interfaces where the response may not originate from the same endpoint that the original destination endpoint was sent to. This only affects udp and icmp protocol pings.
This is enabled by default.
Set whether or not the connect behavior should enforce remote service availability as well as reachability. Normally, if the remote server reported ECONNREFUSED, it must have been reachable because of the status packet that it reported. With this option enabled, the full three-way tcp handshake must have been established successfully before it will claim it is reachable. NOTE: It still does nothing more than connect and disconnect. It does not speak any protocol (i.e., HTTP or FTP) to ensure the remote server is sane in any way. The remote server CPU could be grinding to a halt and unresponsive to any clients connecting, but if the kernel throws the ACK packet, it is considered alive anyway. To really determine if the server is responding well would be application specific and is beyond the scope of Net::Ping. For udp protocol, enabling this option demands that the remote server replies with the same udp data that it was sent as defined by the udp echo service.
This affects the 'udp', 'tcp', and 'syn' protocols.
This is disabled by default.
Deprecated method, but does the same as service_check() method.
With 1 causes this module to use Time::HiRes module, allowing milliseconds to be returned by subsequent calls to ping().
The current time, hires or not.
Sets or clears the O_NONBLOCK flag on a file handle.
With argument sets the option. Without returns the option value.

With argument sets the option. Without returns the option value.
With argument sets the option. Without returns the option value.
Sets ipv6 reachability IPV6_REACHCONF was removed in RFC3542. ping6 -R supports it. IPV6_REACHCONF requires root/admin permissions.
With argument sets the option. Without returns the option value.
Not yet implemented.
Sets the source address from which pings will be sent. This must be the address of one of the interfaces on the local host. $local_addr may be specified as a hostname or as a text IP address such as '192.168.1.1'.
If the protocol is set to 'tcp', this method may be called any number of times, and each call to the ping() method (below) will use the most recent $local_addr. If the protocol is 'icmp' or 'udp', then bind() must be called at most once per object, and (if it is called at all) must be called before the first call to ping() for that object.
The bind() call can be omitted when specifying the
bind
option to new().When you are using the 'icmp' protocol, this call permit to change the message type to 'echo' or 'timestamp' (only for IPv4, see RFC 792).
Without argument, it returns the currently used icmp protocol message type. By default, it returns 'echo'.
When you are using the 'stream' protocol, this call pre-opens the tcp socket. It's only necessary to do this if you want to provide a different timeout when creating the connection, or remove the overhead of establishing the connection from the first ping. If you don't call
open()
, the connection is automatically opened the first time ping()
is called. This call simply does nothing if you are using any protocol other than stream.The $host argument can be omitted when specifying the
host
option to new().When using the 'syn' protocol, use this method to determine the reachability of the remote host. This method is meant to be called up to as many times as ping() was called. Each call returns the host (as passed to ping()) that came back with the TCP ACK. The order in which the hosts are returned may not necessarily be the same order in which they were SYN queued using the ping() method. If the timeout is reached before the TCP ACK is received, or if the remote host is not listening on the port attempted, then the TCP connection will not be established and ack() will return undef. In list context, the host, the ack time, the dotted ip string, and the port number will be returned instead of just the host. If the optional
$host
argument is specified, the return value will be pertaining to that host only. This call simply does nothing if you are using any protocol other than 'syn'.When 'new' had a host option, this host will be used. Without
$host
argument, all hosts are scanned.The reason that
host $failed_ack_host
did not receive a valid ACK. Useful to find out why when ack($fail_ack_host)
returns a false value.Easyping 2 5 – Ping Client To Determine Host Accessibility Guide
The variant called by 'ack' with the 'syn' protocol and
$syn_forking
enabled.The 'ping' method used with the icmp protocol.
The 'ping' method used with the icmpv6 protocol.
The 'ping' method used with the stream protocol.
Perform a stream ping. If the tcp connection isn't already open, it opens it. It then sends some data and waits for a reply. It leaves the stream open on exit.
The 'ping' method used with the syn protocol. Sends a TCP SYN packet to host specified.
The 'ping' method used with the forking syn protocol.
The 'ping' method used with the tcp protocol.
The 'ping' method used with the udp protocol.
Perform a udp echo ping. Construct a message of at least the one-byte sequence number and any additional data bytes. Send the message out and wait for a message to come back. If we get a message, make sure all of its parts match. If they do, we are done. Otherwise go back and wait for the message until we run out of time. Return the result of our efforts.
The 'ping' method used with the external protocol. Uses Net::Ping::External to do an external ping.
Initiates a TCP connection, for a tcp ping.
Performs a TCP echo. It writes the given string to the socket and then reads it back. It returns 1 on success, 0 on failure.
Close the network connection for this ping object. The network connection is also closed by 'undef $p'. The network connection is automatically closed if the ping object goes out of scope (e.g. $p is local to a subroutine and you leave the subroutine).
When called with a port number, the port number used to ping is set to
$port_number
rather than using the echo port. It also has the effect of calling $p->service_check(1)
causing a ping to return a successful response only if that specific port is accessible. This function returns the value of the port that 'ping' will connect to.A
select()
wrapper that compensates for platform peculiarities.Platform abstraction over
inet_ntop()
Do a checksum on the message. Basically sum all of the short words and fold the high order bits into the low order bits.
Returns a list of addr, type, subcode.
To provide backward compatibility with the previous version of Net::Ping, a
pingecho()
subroutine is available with the same functionality as before. pingecho()
uses the tcp protocol. The return values and parameters are the same as described for the 'ping' method. This subroutine is obsolete and may be removed in a future version of Net::Ping.Emit the popular wake-on-lan magic udp packet to wake up a local device. See also Net::Wake, but this has the mac address as 1st arg.
$host
should be the local gateway. Without it will broadcast.Default host: '255.255.255.255' Default port: 9
There will be less network overhead (and some efficiency in your program) if you specify either the udp or the icmp protocol. The tcp protocol will generate 2.5 times or more traffic for each ping than either udp or icmp. If many hosts are pinged frequently, you may wish to implement a small wait (e.g. 25ms or more) between each ping to avoid flooding your network with packets.
The icmp and icmpv6 protocols requires that the program be run as root or that it be setuid to root. The other protocols do not require special privileges, but not all network devices implement tcp or udp echo.
Local hosts should normally respond to pings within milliseconds. However, on a very congested network it may take up to 3 seconds or longer to receive an echo packet from the remote host. If the timeout is set too low under these conditions, it will appear that the remote host is not reachable (which is almost the truth).
Reachability doesn't necessarily mean that the remote host is actually functioning beyond its ability to echo packets. tcp is slightly better at indicating the health of a system than icmp because it uses more of the networking stack to respond.
Because of a lack of anything better, this module uses its own routines to pack and unpack ICMP packets. It would be better for a separate module to be written which understands all of the different kinds of ICMP packets.

Ping is a very useful standard utility that is used to test the connection between computers. It can be found built into Windows as early as Windows 95 and up to the current Windows 8.1 and even on other operating systems such as Linux and Mac OS. Normally when there is a connection problem for a computer, the first thing an administrator or technician would do is run a ping test between the computers and see if there is a reply. If there is a ping reply, it rules out that the problem is related to the network connection.
As useful as it is, hackers can also use ping to scan a network subnet to find potential online computers that are easy to break into due to misconfiguration on the security settings or download your files from folders that are openly shared without authentication. That is why there are situations when there is no need to reply to ping requests such as when you’re connected to a public Wi-Fi. Even the newer Windows operating systems are smart enough to block ping requests if you’ve selected your network location as public network.
If you want to disable or enable ping requests, here we’ll show you some common places to check.
First of all, you need to determine if you want to enable or disable ping reply on an internal or external network. For external ping request, you’ll need to configure your router instead of your computer. To see if an external source can ping your IP address, visit ping.eu, click on your IP address that is shown on the webpage and click the Go button. If you see a 100% packet loss that means your router/network is already safe from external ping. However, if ping.eu shows result like the screenshot below, that means your router/network is responding to ping requests.You may want to refer to your router’s manual on how to access your router’s configuration and check the firewall settings. Below is a screenshot of a Belkin ADSL router’s settings that can be configured to block ICMP ping. Some routers have very straight forward setting on how to block WAN ping while some can be quite difficult to configure for a novice user.
To enable or disable ping replies for your computer or laptop on an internal network (an example is when you’re connected to a public Wi-Fi), this can be achieved either through the Windows settings or a third party firewall software.
1. ZoneAlarm Free Firewall
For ZoneAlarm Free Firewall, there are only two zones in the software which is Public and Trusted. Zones in ZoneAlarm is automatically selected based on the network location profile in Windows. For example, if you’ve selected Home network as the network location for a Wi-Fi connection, then ZoneAlarm automatically sets the zone as Trusted and vice versa.
If your computer is responding to ping queries, then disabling ping response is as easy as changing the zone from Trusted to Public ZoneAlarm. Launch ZoneAlarm, go to FIREWALL tab, and click on View Zones for Basic Firewall.
At the View Zones tab, select the network that you’re connected to and click the Edit button. Click the dropdown menu for zone and select Public.
If you want to re-enable ping reply, set the network zone back to Trusted.
Download ZoneAlarm Free Firewall
2. Emsisoft Online Armor Free
Emsisoft Online Armor Free will automatically disable ping reply and there is no way to configure the firewall rules to re-enable ping. Unlike the paid version where you can switch to advanced mode to configure the ICMP rules, the free version doesn’t allow you to switch to advanced mode but only allows standard mode. So if you are using the free edition of Online Armor, what you can do is temporarily disable the Firewall protection by right clicking on the Online Armor tray icon and click on Firewall to deselect the checkbox.
If you are using the paid version, run Online Armor, go to Options > General tab > switch to Advanced Mode. Click on Firewall at the left sidebar of the program, go to ICMP tab > select the allowed checkbox for function 0 which is the Echo reply.
Download Emsisoft Online Armor
3. Comodo Free Firewall
Comodo automatically decides if ping should be allowed or blocked based on the network zone that you’ve selected for a connected network.
If you’ve selected either Home or Work, then ping is allowed. However the Public Place network zone blocks ping requests. If you’ve selected Public Place and want to enable ping requests, you can manually configure the global rules to allow ping instead of block.
Right click on the Comodo Firewall tray icon located at the notification area and select Advanced View. Right click on the Comodo Firewall tray icon again, go to Firewall and select Settings. Expand Security Settings > Firewall and select Global Rules. Double click on the rule that says “Block ICMPv4 In From MAC Any To MAC Any Where ICMP Message Is ECHO REQUEST” and change the action from Block to Allow. Click OK to close the firewall rule window and OK again to save the changes.
Alternatively, you can also temporarily disable the firewall from the tray icon to allow Ping replies. Don’t exit or terminate the program because the firewall will still be active even though the tray icon is not shown at the notification area.
On the other hand, if you’re on a Home or Work network zone that allows ping requests and you want to disable ping replies, you just need to move the firewall rule located at the bottom that blocks all ICMP echo request all the way to the top so that it overrides the first two rules that allows all incoming and outgoing requests if target/sender is in home/work zone.
Download Comodo Free Firewall
4. Windows Firewall
It is actually not necessary to rely on third party firewall software to enable or disable ping replies as Windows Firewall can be configured to do that.
4a. Press the WIN key, type WINDOWS FIREWALL and run it.
4b. Click on Advanced settings located at the left hand sidebar.
4c. Click on Inbound Rules at the left pane.
4d. Click Action from the menu bar and select New Rule.
4e. Click on Custom and click Next.
Easyping 2 5 – Ping Client To Determine Host Accessibility Device
4f. Make sure the All programs option is selected and click Next.
4g. Click on the Protocol type drop down menu, select ICMPv4 and click Next.
4h. Make sure both “Any IP address” is selected and click Next.
4i. If you want to enable ping when you are connected to a public network, select “Allow the connection”. If you want to block ping even when you are connected to home network, select “Block the connection” option and click Next.
4j. You can leave all the checkboxes ticked for the profiles and click Next.
4k. Give this new rule any name you like, for example block ping or allow ping and click Finish. The newly created firewall rule will take effect instantly without requiring a reboot.
Additional Note: In the Windows operating system, selecting your network location as Home or Work will allow ping while the Public network profile will block ping. The above Windows Firewall rule will override the network location rule.
