Ask your LAN switch vendor!
Most vendors support "short" if both NICs are connected to one LAN switch, but not if connected to two different LAN switches.
In the worst case a fail-over does not work. Do the "pull the cable" test at least!

I have some linux machines that I am trying to increase the throughput to on a single connection. They connect to a switch with two 1GbE lines and the switch does not have Link Aggregation support for these machines. I have tried bonding with balance-rr, balance-alb, but the machines can only...

Hi,
I need to setup a hacmp cluster (my first one, we usually use VCS on AIX), but I require more network bandwith than a normal gigabit etherchannel setup can provide, so I am thinking about using linkaggregation - 2 active adapters to one switch and a single backup adapter to another switch...

Hi,
Hoping someone can offer some advice on something i have not dealt with before.
We have a server that seems to have some very strange configuration done on it. It has 2 physical NIC's and rather than both be aggregated into LAN900 we have 1 in LAN900 and 1 in LAN901? (See Below)... (2 Replies)

Hi,
I want to Break the Link Aggregation. My aggregation are lan0+lan1 = lan900.
Now I want to break this and put the IP in lan0. But i have cluster environment and this is the main database server.
So It need to change in cluster script.
But I dont know where I have to change it.

Hi,
I'm not from the Solaris world and some of these things are new to me. Can someone tell me if it is possible to configure link aggregation without using LACP?

Authen::Passphrase::LANManagerHalf(3pm) User Contributed Perl Documentation Authen::Passphrase::LANManagerHalf(3pm)
NAME
Authen::Passphrase::LANManagerHalf - passphrases using half the LAN Manager algorithm
SYNOPSIS
use Authen::Passphrase::LANManagerHalf;
$ppr = Authen::Passphrase::LANManagerHalf->new(
hash_hex => "855c3697d9979e78");
$ppr = Authen::Passphrase::LANManagerHalf->new(
passphrase => "passphr");
$ppr = Authen::Passphrase::LANManagerHalf->from_crypt(
'$LM$855c3697d9979e78');
$ppr = Authen::Passphrase::LANManagerHalf->from_rfc2307(
'{CRYPT}$LM$855c3697d9979e78');
$hash = $ppr->hash;
$hash_hex = $ppr->hash_hex;
if($ppr->match($passphrase)) { ...
$passwd = $ppr->as_crypt;
$userPassword = $ppr->as_rfc2307;
DESCRIPTION
An object of this class encapsulates half of a passphrase hashed using the Microsoft LAN Manager hash function. This is a subclass of
Authen::Passphrase, and this document assumes that the reader is familiar with the documentation for that class. For the complete LAN
Manager hash function, see Authen::Passphrase::LANManager.
In a spectacularly bad design decision, the Microsoft LAN Manager hash function splits the passphrase into two parts and hashes them
separately. It is therefore possible to separate the halves of a LAN Manager hash, and do things with them (such as crack them)
separately. This class is about using such a hash half on its own.
The half hash algorithm can be used on up to seven Latin-1 characters of passphrase. First the passphrase is folded to uppercase, and
zero-padded to seven bytes. Then the seven bytes are used as a 56-bit DES key, to encrypt the fixed plaintext block "KGS!@#$%". The eight
byte ciphertext block is the half hash. There is no salt.
Warning: Don't even think about using this seriously. It's an exceptionally weak design, flawed in pretty much every respect.
CONSTRUCTORS
Authen::Passphrase::LANManagerHalf->new(ATTR => VALUE, ...)
Generates a new passphrase recogniser object using the LAN Manager half hash algorithm. The following attributes may be given:
hash
The hash, as a string of 8 bytes.
hash_hex
The hash, as a string of 16 hexadecimal digits.
passphrase
A passphrase that will be accepted.
Either the hash or the passphrase must be given.
Authen::Passphrase::LANManagerHalf->from_crypt(PASSWD)
Generates a new LAN Manager half passphrase recogniser object from a crypt string. The crypt string must consist of "$LM$" followed by
the hash in lowercase hexadecimal.
Authen::Passphrase::LANManagerHalf->from_rfc2307(USERPASSWORD)
Generates a new LAN Manager half passphrase recogniser object from an RFC 2307 string. The string must consist of "{CRYPT}" (case
insensitive) followed by an acceptable crypt string.
METHODS
$ppr->hash
Returns the hash value, as a string of 8 bytes.
$ppr->hash_hex
Returns the hash value, as a string of 16 hexadecimal digits.
$ppr->match(PASSPHRASE)
$ppr->as_crypt
$ppr->as_rfc2307
These methods are part of the standard Authen::Passphrase interface.
