Can you show us the output from the following (assuming we're looking at ent0):-
Please paste the output in [CODE] & [/CODE] tags to make the output clear like this:-

i purchased, what was labeled as a 4-port fast ethernet sbus card from ebay.
i installed it in my ultra1, and it seems to be working fine. how can i determine if the card is infact a fast ethernet card vs. the standard ethernet 4-port card? (7 Replies)
I am trying to find a command to return the "link" speed of the networks installed on AIX.
ifconfig - gives me where the link is up and the duplex setting. I need to determine for example if the ethernet connection is 10, 100, 1000 Mbs or what the current speed is based on the network media... (3 Replies)
hai this is nagesh
when i was doing practical , i find some dought.
iam using solaris 9. how can i see the ethernet card speed , wheather it is halfduplex or full duplex.any body please help me (4 Replies)
hi ,
i have to tranfer some 12 - 13 gb of files from one server to anothier presently i m using the SFTP but it is taking to much time to trafer the files is there any way to use increase the efficiency of SFTP.
i cant use the FTP (4 Replies)
Hi guys,
Suppose you have a server with two ethernet cards (1GB each) and each cards are connecting to two different switches cisco 3750. My question is:
How can I setup my server's network interfaces to increase the throughput up to 2GB? is it possible? If not, do you know another way to up... (3 Replies)
Hi,
Does anyone know how can I determine the maximum capable speed on a network interface card for different OS like HP, Sun, AIX and Linux.
I am aware of the tool "ethtool" which can be used for Linux. Are there any handly commands or /proc files where I can get this info depending on the OS.... (3 Replies)
Hi,
Will removing space from the server increases the speed/performance.
how are they related?
please explain the relationship. thanks in advance

Hi All,
Please let me know the step by step process to set the e1000g0 interface speed to 1000mbps with full duplex from 100fdx and how to disable the auto negotiation with switch?.
Thanks and Regards,

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.
