Hi all..
I'm secering a RH 2.1 server, with gnome (not my choice...), as X manager.
Is ther anyway to get sudo ask for root password other then the actual user's password? Like when you launch the graphical IHM to create a new user, it asks for root's password? Is there a way to do the same... (5 Replies)

I'm actually working with a Ubuntu-System here and have a question about executing a command with 'sudo'.
I tried and got a error message like "not allowed".
After this I logged in with 'sudo -s' and typed the command without 'sudo'. This worked well.
Can please somebody explain me this... (0 Replies)
I've been through many threads before i decide to create a separate thread.
I can't really find the solution to my (simple) problem.

As "canar" user I want to run a command, let's say "/opt/ocaml/bin/ocaml" as "duck" user.
The only to achieve this is to... (1 Reply)

How to avoid this from happening coz i need all the users to use su - only. (2 Replies)
Hi All,
I need to give an user sudo ability to root.
We have also generated RSA key but unable to proceed further.
For example after a user logs into the server normally and when he executes below command
$ssh root@server_name
This should take you to root prompt #

My friend has found a bug with sudo.
His organization has Linux laptops with no root access to users. Policy pushing is through Puppet.
But doing sudo sudo twice he is able to access root.
Do you guys have any clue, how's that possible, usually sudo su is restricted. (8 Replies)

Hello,
It is Solaris-10. There is a file as /opt/vpp/dom1.2/pdd/today_23. It is always generated by root, so owned by root only.
This file has to be deleted as part of application restart always and that is done by app_user and SA is always involved to do rm on that file.
Is it possible to give... (9 Replies)

devel::refcount
Devel::Refcount(3pm) User Contributed Perl Documentation Devel::Refcount(3pm)NAME
"Devel::Refcount" - obtain the REFCNT value of a referent
SYNOPSIS
use Devel::Refcount qw( refcount );
my $anon = [];
print "Anon ARRAY $anon has " . refcount($anon) . " reference
";
my $otherref = $anon;
print "Anon ARRAY $anon now has " . refcount($anon) . " references
";
DESCRIPTION
This module provides a single function which obtains the reference count of the object being pointed to by the passed reference value.
FUNCTIONS
$count = refcount($ref)
Returns the reference count of the object being pointed to by $ref.
COMPARISON WITH SvREFCNT
This function differs from "Devel::Peek::SvREFCNT" in that SvREFCNT() gives the reference count of the SV object itself that it is passed,
whereas refcount() gives the count of the object being pointed to. This allows it to give the count of any referent (i.e. ARRAY, HASH,
CODE, GLOB and Regexp types) as well.
Consider the following example program:
use Devel::Peek qw( SvREFCNT );
use Devel::Refcount qw( refcount );
sub printcount
{
my $name = shift;
printf "%30s has SvREFCNT=%d, refcount=%d
",
$name, SvREFCNT($_[0]), refcount($_[0]);
}
my $var = [];
printcount 'Initially, $var', $var;
my $othervar = $var;
printcount 'Before CODE ref, $var', $var;
printcount '$othervar', $othervar;
my $code = sub { undef $var };
printcount 'After CODE ref, $var', $var;
printcount '$othervar', $othervar;
This produces the output
Initially, $var has SvREFCNT=1, refcount=1
Before CODE ref, $var has SvREFCNT=1, refcount=2
$othervar has SvREFCNT=1, refcount=2
After CODE ref, $var has SvREFCNT=2, refcount=2
$othervar has SvREFCNT=1, refcount=2
Here, we see that SvREFCNT() counts the number of references to the SV object passed in as the scalar value - the $var or $othervar
respectively, whereas refcount() counts the number of reference values that point to the referent object - the anonymous ARRAY in this
case.
Before the CODE reference is constructed, both $var and $othervar have SvREFCNT() of 1, as they exist only in the current lexical pad. The
anonymous ARRAY has a refcount() of 2, because both $var and $othervar store a reference to it.
After the CODE reference is constructed, the $var variable now has an SvREFCNT() of 2, because it also appears in the lexical pad for the
new anonymous CODE block.
PURE-PERL FALLBACK
An XS implementation of this function is provided, and is used by default. If the XS library cannot be loaded, a fallback implementation in
pure perl using the "B" module is used instead. This will behave identically, but is much slower.
