Hi,
I would like to setup a FOR loop script to find out all the existing linux workstation in the network w/ ip address, hostname and linux version.
I created a basic FOR loop script:
for i in $(seq 1 254)
do
echo 10.72.169.$i >> result
ssh -o ConnectTimeout=3 root@10.72.169.$i... (14 Replies)
I need some help to write a C++ code that read and write the register of a sequencer. I have to make a code that relate the objects with the physical address but I am a bit confuse. Could someone suggest me how to proceed? in which parts do I split the code?
thanks (1 Reply)
We want to use RADIUS to authenticate our AIX server logins. Can anybody tell me how to set on AIX server up to use a Radius server to authenticate or point me to documentation on setting up AIX to use Radius to authenticate user login.
Our problem is that we have a few users that access our... (1 Reply)
I guess I probably ask a dumb question but why use RADIUS for authentication as there are many ways to do it, as authentication is basically a user/password check?
What is the benifit(s) of using it ?
Thanks! (3 Replies)

POE::Filter::Map(3pm) User Contributed Perl Documentation POE::Filter::Map(3pm)NAME
POE::Filter::Map - transform input and/or output within a filter stack
SYNOPSIS
#!perl
use POE qw(
Wheel::FollowTail
Filter::Line Filter::Map Filter::Stackable
);
POE::Session->create(
inline_states => {
_start => sub {
my $parse_input_as_lines = POE::Filter::Line->new();
my $redact_some_lines = POE::Filter::Map->new(
Code => sub {
my $input = shift;
$input = "[REDACTED]" unless $input =~ /sudo[d+]/i;
return $input;
},
);
my $filter_stack = POE::Filter::Stackable->new(
Filters => [
$parse_input_as_lines, # first on get, last on put
$redact_some_lines, # first on put, last on get
]
);
$_[HEAP]{tailor} = POE::Wheel::FollowTail->new(
Filename => "/var/log/system.log",
InputEvent => "got_log_line",
Filter => $filter_stack,
);
},
got_log_line => sub {
print "Log: $_[ARG0]
";
}
}
);
POE::Kernel->run();
exit;
DESCRIPTION
POE::Filter::Map transforms data inside the filter stack. It may be used to transform input, output, or both depending on how it is
constructed. This filter is named and modeled after Perl's built-in map() function.
POE::Filter::Map is designed to be combined with other filters through POE::Filter::Stackable. In the "SYNOPSIS" example, a filter stack
is created to parse logs as lines and redact all entries that don't pertain to a sudo process.
PUBLIC FILTER METHODS
In addition to the usual POE::Filter methods, POE::Filter::Map also supports the following.
new
new() constructs a new POE::Filter::Map object. It must either be called with a single Code parameter, or both a Put and a Get parameter.
The values for Code, Put and Get are code references that, when invoked, return transformed versions of their sole parameters. A Code
function will be used for both input and output, while Get and Put functions allow input and output to be filtered in different ways.
# Decrypt rot13.
sub decrypt_rot13 {
my $encrypted = shift;
$encrypted =~ tr[a-zA-Z][n-za-mN-ZA-M];
return $encrypted;
}
# Encrypt rot13.
sub encrypt_rot13 {
my $plaintext = shift;
$plaintext =~ tr[a-zA-Z][n-za-mN-ZA-M];
return $plaintext;
}
# Decrypt rot13 on input, and encrypt it on output.
my $rot13_transcrypter = POE::Filter::Map->new(
Get => &decrypt_rot13,
Put => &encrypt_rot13,
);
Rot13 is symmetric, so the above example can be simplified to use a single Code function.
my $rot13_transcrypter = POE::Filter::Map->new(
Code => sub {
local $_ = shift;
tr[a-zA-Z][n-za-mN-ZA-M];
return $_;
}
);
modify
modify() changes a POE::Filter::Map object's behavior at run-time. It accepts the same parameters as new(), and it replaces the existing
transforms with new ones.
# Switch to "reverse" encryption for testing.
$rot13_transcrypter->modify(
Code => sub { return scalar reverse shift }
);
