Instead of sending to one target until it times out or replies, fping will send out a ping packet and move on to the next target in a round-robin fashion. In the default mode, if a target replies, it is noted and removed from the list of targets to check; if a target does not respond within a certain time limit and/or retry limit it is designated as unreachable.fping google.com yahoo.com facebook.comgoogle.com is aliveyahoo.com is alivefacebook.com is alive#fping google.com yahoo.com facebook.com nogoogle.comgoogle.com is aliveyahoo.com is alivefacebook.com is alivenogoogle.com is unreachableWe can make file and add IPs or hostnames in the file to feed fping command.$cat ips.txtgoogle.comfacebook.comyahoo.comnogoogle.com#fping -f ips.txtgoogle.com is aliveyahoo.com is alivefacebook.com is alivenogoogle.com is unreachableWith fping we use switch -f for reading file containing destination hosts.

Examples of fping Command in Linux - Command Examples

"-" indicating that no response was received to the fourth request. -d Use DNS to lookup address of return ping packet. This allows you to give fping a list of IP addresses as input and print hostnames in the output. -D Add Unix timestamps in front of output lines generated with in looping or counting modes (-l, -c, or -C). -e Show elapsed (round-trip) time of packets. -f Read list of targets from a file. This option can only be used by the root user. Regular users should pipe in the file via stdin: % fping -g addr/mask Generate a target list from a supplied IP netmask, or a starting and ending IP. Specify the netmask or start/end in the targets portion of the command line. If a network with netmask is given, the network and broadcast addresses will be excluded. ex. To ping the network 192.168.1.0/24, the specified command line could look like either: fping -g 192.168.1.0/24 or fping -g 192.168.1.1 192.168.1.254 -h Print usage message. -i n The minimum amount of time (in milliseconds) between sending a ping packet to any target (default is 25). -l Loop sending packets to each target indefinitely. Can be interrupted with Ctrl-C; statistics about responses for each target are then displayed. -m Send pings to each of a target host's multiple interfaces. -n Same as -d. -p In looping or counting modes (-l, -c, or -C), this parameter sets the time in milliseconds that fping waits between successive packets to an individual target. Default is 1000. -q Quiet. Don't show per-probe results, but only the final summary. Also don't show ICMP error messages. -Q n Like -q, but show summary results every n seconds. -r n Retry limit (default 3). This is the number of times an attempt at pinging a target will be made, not including the first try. -s Print cumulative statistics upon exit. -S addr Set source address. -I if Set the interface (requires SO_BINDTODEVICE support) -t n Initial target timeout in milliseconds (default 500). In the default mode, this is the amount of time that fping waits for a response to its first request. Successive timeouts are multiplied by the backoff factor. -T n Ignored (for compatibility with fping 2.4). -u Show targets that are unreachable. -O n Set the typ of service flag (TOS). n can be either decimal or hexadecimal (0xh) format. -v Print fping version information. -H n Set the IP TTL field (time to live hops).AUTHORS • Roland J.

fping – How to make fping result always sequential in order of command

Provided by: fping_3.8-1_amd64 NAME fping - send ICMP ECHO_REQUEST packets to network hostsSYNOPSIS fping [ options ] [ systems... ] fping6 [ options ] [ systems... ]DESCRIPTION fping is a program like ping which uses the Internet Control Message Protocol (ICMP) echo request to determine if a target host is responding. fping differs from ping in that you can specify any number of targets on the command line, or specify a file containing the lists of targets to ping. Instead of sending to one target until it times out or replies, fping will send out a ping packet and move on to the next target in a round-robin fashion. In the default mode, if a target replies, it is noted and removed from the list of targets to check; if a target does not respond within a certain time limit and/or retry limit it is designated as unreachable. fping also supports sending a specified number of pings to a target, or looping indefinitely (as in ping ). Unlike ping, fping is meant to be used in scripts, so its output is designed to be easy to parse. The binary named fping6 is the same as fping, except that it uses IPv6 addresses instead of IPv4.OPTIONS -a Show systems that are alive. -A Display targets by address rather than DNS name. -b n Number of bytes of ping data to send. The minimum size (normally 12) allows room for the data that fping needs to do its work (sequence number, timestamp). The reported received data size includes the IP header (normally 20 bytes) and ICMP header (8 bytes), so the minimum total size is 40 bytes. Default is 56, as in ping. Maximum is the theoretical maximum IP datagram size (64K), though most systems limit this to a smaller, system-dependent number. -B n In the default mode, fping sends several requests to a target before giving up, waiting longer for a reply on each successive request. This parameter is the value by which the wait time is multiplied on each successive request; it must be entered as a floating-point number (x.y). The default is 1.5. -c n Number of request packets to send to each target. In this mode, a line is displayed for each received response (this can suppressed with -q or -Q). Also, statistics about responses for each target are displayed when all requests have been sent (or when interrupted). -C n Similar to -c, but the per-target statistics are displayed in a format designed for automated response-time statistics gathering. For example: % fping -C 5 -q somehost somehost : 91.7 37.0 29.2 - 36.8 shows the response time in milliseconds for each of the five requests, with the New Binary ! fping 4.2 (2019-02-19 released 3yrs ago)======================Can anyone reverse this so we can compile new version?If you wish to see the V3 with gui then see inside folders ;)Or else use the binary/cmd mode on the new 4.2Can anyone reverse the v3 so we can compile new GUI version?fping 4.2 (2019-02-19)New featuresNew option -x / --reachable to check if the number of reachable hosts is >= a certainnumber.

It means that, for example,doing 'fping google.com' is going to ping the IPv6 IP of google.com onIPv6-enabled hosts.If you need exact compatibility with old versions, you can configure andinstall fping twice: once for ipv4, and once for ipv6:./configure --disable-ipv6; make clean install./configure --disable-ipv4 --program-suffix=6; make clean installOption -n, not the same as -d anymoreOption -n / --name is now doing a reverse-DNS lookups on host addresses,only if they are given as IP address, but not for hostnames. For example,if you write 'fping -n google.com', fping would previously do aforward-DNS lookup on google.com, and then a reverse-DNS lookup on theresolved IP address. Now, it is just going to keep the name 'google.com'.That same behavior can be achieved with the option -d / --rdns (which waspreviously an alias for

How to Use the Command 'fping' (with Examples)

Can create some issues, though. For instance, anything other than a simple port scan will cause a conflict with the local TCP/IP stack. You can circumvent this by either using the -S option to use a separate IP address or by configuring your operating system to firewall the ports that the tool uses. Although this is primarily a Linux tool, it is also available for Mac OS X. Its main drawback is the lack of a graphical user interface but this is largely compensated by the tool’s blazing speed.6. ZMapZMap is a fast single packet network scanner developed at the University of Michigan and designed for Internet-wide network surveys. Perhaps not as much as the previous selection, this is also a fast tool. On a typical desktop computer with a gigabit ethernet connection, it is capable of scanning the entire public IPv4 address space in under 45 minutes. With a 10 gigabit connection and PF_RING, it can scan the IPv4 address space in under 5 minutes. Zmap is available for Mac OS X but also for Linux and for BSD. On a Mac, installation is simple through Homebrew.The tool does not solely rely on ping to scan networks. It currently has fully implemented probe modules for TCP SYN scans, ICMP, DNS queries, UPnP, and BACNET. It can also send a large number of UDP probes. If you are looking to do more involved scans such as banner grab or TLS handshake, you might want to have a look at ZGrab, another project from the University of Michigan. This Zmap sibling can perform stateful application-layer handshakes. Like the previous entry, ZMap is essentially a text-based tool.7. FpingFping was created as an improvement over ping, then one of the only network troubleshooting tool. It is a similar command-line tool yet it is quite different. Like ping, Fping uses ICMP echo requests to determine if the target hosts are responding but this is pretty much where the similarity ends. Unlike ping, Fping can be called with many target IP addresses. The targets can be specified as a space-delimited list of IP addresses. The utility can also be provided with the name of a text file containing a list of addresses. Finally, an IP address range can be specified or a subnet can be entered in CIDR notation such as 192.168.0.0/24.Fping is relatively fast as it does not wait for a response before sending

The next echo request, that way, it doesn’t lose time waiting for unresponsive IP addresses. Fping also has lots of command-line options that you can use. Since this is a command-line tool, you can pipe its output to another command for further processing. This tool can easily be installed on Mac OS X using Homebrew. 8. HpingHping is another free command-line tool derived from ping. It is available on Mac OS X as well as most Unix-like operating systems and Windows. Although it is no longer in active development, it is still in widespread use, a testament to how good a tool it is. The tool closely resembles ping but with several differences. For starters, Hping won’t only send ICMP echo requests. It can also send TCP, UDP or RAW-IP packets. It also features a traceroute mode and it has the ability to send files.Although Hping can be used as an IP address scanning tool, it can do quite a bit more than that. The tool has some advanced ports scanning features. Thanks to its use of multiple protocols, it can also be used to perform basic network testing. This tool also has some advanced traceroute capabilities using any of the available protocols. This can be useful as some devices treat ICMP traffic differently from other traffic. By mimicking other protocols, this tool can give you a better evaluation of your network’s true, real-time performance.
