Uses the telnet protocol +to run a ping from an JunOS device (source) to another device (host). +This probe basically uses the "extended ping" of the Juniper JunOS. You have +the option to specify which interface the ping is sourced from as well. +DOC + notes => <<DOC, +${e}head2 JunOS configuration + +The JunOS device should have a username/password configured, as well as +the ability to connect to the VTY(s). + +Some JunOS devices have a maximum of 5 VTYs available, so be careful not +to hit a limit with the 'forks' variable. + +${e}head2 Requirements + +This module requires the Net::Telnet module for perl. This is usually +included on most newer OSs which include perl. + +${e}head2 Debugging + +There is some VERY rudimentary debugging code built into this module (it's +based on the debugging code written into Net::Telnet). It will log +information into three files "TIPreturn", "TIPoutlog", and "TIPdump". +These files will be written out into your current working directory (CWD). +You can change the names of these files to something with more meaning to +you. + +${e}head2 Password authentication + +You should be advised that the authentication method of telnet uses +clear text transmissions...meaning that without proper network security +measures someone could sniff your username and password off the network. +I may attempt to incorporate SSH in a future version of this module, but +it is very doubtful. Right now SSH adds a LOT of processing overhead to +a router, and isn't incredibly easy to implement in perl. + +Having said this, don't be too scared of telnet. Remember, the +original JunOSPing module used RSH, which is even more scary to use from +a security perspective. + +${e}head2 Ping packet size + +The FPing manpage has the following to say on the topic of ping packet +size: + +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. +DOC + authors => <<'DOC', +S H A N <shanali@yahoo.com> + +based HEAVILY on Smokeping::probes::TelnetIOSPing by + +John A Jackson <geonjay@infoave.net> + +based on Smokeping::probes::JunOSPing by + +Paul J Murphy <paul@murph.org> + +based on Smokeping::probes::FPing by + +Tobias Oetiker <tobi@oetiker.ch> +DOC + } +} + +sub new($$$) +{ + my $proto = shift; + my $class = ref($proto) || $proto; + my $self = $class->SUPER::new(@_); + + # no need for this if we run as a cgi + unless ( $ENV{SERVER_SOFTWARE} ) { + $self->{pingfactor} = 1000; # Gives us a good-guess default + print "### assuming you are using an JunOS reporting in miliseconds\n"; + }; + + return $self; +} + +sub ProbeDesc($){ + my $self = shift; + my $bytes = $self->{properties}{packetsize}; + return "InfoAve Juniper JunOS - ICMP Echo Pings ($bytes Bytes)"; +} + +sub pingone ($$){ + my $self = shift; + my $target = shift; + my $source = $target->{vars}{source}; + my $dest = $target->{vars}{host}; + my $psource = $target->{vars}{psource}; + my $port = 23; + my @output = (); + my $login = $target->{vars}{junosuser}; + my $pssword = $target->{vars}{junospass}; + my $bytes = $self->{properties}{packetsize}; + my $pings = $self->pings($target); + + # do NOT call superclass ... the ping method MUST be overwriten + my %upd; + my @args = (); + + + my $telnet = Net::Telnet->new(Timeout => 60); +# $telnet->errmode("TIPreturn"); +# $telnet->input_log("TIPinlog"); +# $telnet->dump_log("TIPdumplog"); + +# Open the Connection to the router +# open(OUTF,">outfile.IA") || die "Can't open OUTF: $!"; +# print OUTF "target => $dest\nsource => $source\nuser => $login\n"; + my $ok = $telnet->open(Host => $source, + Port => $port); + print OUTF "Connection is a $ok\n"; + + #Authenticate + $telnet->waitfor('/(ogin):.*$/'); + $telnet->print("$login"); + $telnet->waitfor('/word:.*$/'); + $telnet->print("$pssword"); + $telnet->prompt('/[\@\w\-\.]+[>#][ ]*$/'); + #Do the work + $telnet->waitfor('/[\@\w\-\.]+[>#][ ]*$/'); + $telnet->print("set cli screen-length 0"); + $telnet->waitfor('/[\@\w\-\.]+[>#][ ]*$/'); + @output = $telnet->cmd("ping $dest count $pings size $bytes source $psource"); + $telnet->print("quit"); + $telnet->close; + print OUTF "closed Telnet connection\n"; + + my @times = (); + while (@output) { + my $outputline = shift @output; + chomp($outputline); + print OUTF "$outputline\n"; + $outputline =~ /^\d+ bytes from $dest: icmp_seq=\d+ ttl=\d+ time=(\d+\.\d+) ms$/ && push(@times,$1); + #print OUTF "$outputline => $1\n"; + } + @times = map {sprintf "%.10e", $_ / $self->{pingfactor}} sort {$a <=> $b} @times; +# close(OUTF); + return @times; +} + +sub probevars { + my $class = shift; + return $class->_makevars($class->SUPER::probevars, { + packetsize => { + _doc => <<DOC, +The (optional) packetsize option lets you configure the packetsize for +the pings sent. +DOC + _default => 100, + _re => '\d+', + _sub => sub { + my $val = shift; + return "ERROR: packetsize must be between 12 and 64000" + unless $val >= 12 and $val <= 64000; + return undef; + }, + }, + }); +} + +sub targetvars { + my $class = shift; + return $class->_makevars($class->SUPER::targetvars, { + _mandatory => [ 'junosuser', 'junospass', 'source' ], + source => { + _doc => <<DOC, +The source option specifies the JunOS device to which we telnet.
