I work for a small internet company, and sometimes its useful to ping a certain IP over an open amount of time. I wrote a simple script that asks what IP you'd like to ping, and then pings it and puts it into a text file so that you can save the results. What i'd like though, is to have an infinite loop that pings and puts it into a text file, and then, after a certain key is pressed, it stops that part of the script and continues on to the next part, that uses Grep, and filters out the pings so that you just get the time, and and the end part of the ping, where it tells you packet loss and such. This is what I have so far. I know it is likely completely wrong, I'm new to this, and this is what I have combining my script and what I think I want from googling how to use user input to end an infinite loop.

DESCRIPTION
Connect to Juniper JunOS via OpenSSH to run ping commands. This probe uses the "extended ping" of the Juniper JunOS. You have the option
to specify which interface the ping is sourced from as well.
VARIABLES
Supported probe-specific variables:
forks
Run this many concurrent processes at maximum
Example value: 5
Default value: 5
offset
If you run many probes concurrently you may want to prevent them from hitting your network all at the same time. Using the probe-
specific offset parameter you can change the point in time when each probe will be run. Offset is specified in % of total interval, or
alternatively as 'random', and the offset from the 'General' section is used if nothing is specified here. Note that this does NOT
influence the rrds itself, it is just a matter of when data acqusition is initiated. (This variable is only applicable if the variable
'concurrentprobes' is set in the 'General' section.)
Example value: 50%
packetsize
The (optional) packetsize option lets you configure the packetsize for the pings sent.
Default value: 100
step
Duration of the base interval that this probe should use, if different from the one specified in the 'Database' section. Note that the
step in the RRD files is fixed when they are originally generated, and if you change the step parameter afterwards, you'll have to
delete the old RRD files or somehow convert them. (This variable is only applicable if the variable 'concurrentprobes' is set in the
'General' section.)
Example value: 300
timeout
How long a single 'ping' takes at maximum
Example value: 15
Default value: 5
Supported target-specific variables:
junospass
The junospass option allows you to specify the password for the username specified with the option junosuser.
Example value: password
This setting is mandatory.
junosuser
The junosuser option allows you to specify a username that has ping capability on the JunOS Device.
Example value: user
This setting is mandatory.
pings
How many pings should be sent to each target, if different from the global value specified in the Database section. Note that the
number of pings in the RRD files is fixed when they are originally generated, and if you change this parameter afterwards, you'll have
to delete the old RRD files or somehow convert them.
Example value: 5
psource
The (optional) psource option specifies an alternate IP address or Interface from which you wish to source your pings from. Routers
can have many many IP addresses, and interfaces. When you ping from a router you have the ability to choose which interface and/or
which IP address the ping is sourced from. Specifying an IP/interface does not necessarily specify the interface from which the ping
will leave, but will specify which address the packet(s) appear to come from. If this option is left out the JunOS Device will source
the packet automatically based on routing and/or metrics. If this doesn't make sense to you then just leave it out.
Example value: 192.168.2.129
source
The source option specifies the JunOS device that is going to run the ping commands. This address will be used for the ssh connection.
Example value: 192.168.2.1
This setting is mandatory.

NOTES
JunOS configuration
The JunOS device should have a username/password configured, as well as the ability to connect to the VTY(s).
Make sure to connect to the remote host once from the commmand line as the user who is running smokeping. On the first connect ssh will ask
to add the new host to its known_hosts file. This will not happen automatically so the script will fail to login until the ssh key of your
juniper box is in the known_hosts file.
Some JunOS devices have a maximum of 5 VTYs available, so be careful not to hit a limit with the 'forks' variable.
Requirements
This module requires the Net::OpenSSH and IO::Pty.
