Bank on analytics for understanding customers better

Bank on analytics for understanding customers better.

 

by Khalid Raza

Ever since the commercialization of the internet, and the advent of social media, customer-centricity has become a norm across industries. For banks in particular, this extends new customer touch points, implying the opportunity to relook at segmentation, channels and pricing. …”

Do you remember? “Log On Using Dial Up Connection”, now think DirectAccess or DA.

Nevermind !

Microsoft suggest a new “possible” way.

” DirectAccess allows remote users to securely access internal network file shares, Web sites, and applications without connecting to a virtual private network (VPN). An internal network is also known as a private network or intranet. DirectAccess establishes bi-directional connectivity with an internal network every time a DirectAccess-enabled computer connects to the Internet, even before the user logs on. Users never have to think about connecting to the internal network and IT administrators can manage remote computers outside the office, even when the computers are not connected to the VPN. ”

What is cloud?

Computing as a service over the Internet

Cloud computing, often referred to as simply “the cloud,” is the delivery of on-demand computing resources—everything from applications to data centers—over the Internet on a pay-for-use basis.

Já parou para pensar o que significa aquele total lá em cima, logo após a execução do comando ls -l ?
Certa vez você já deve ter escutado os antigos, falarem em “blocagem” pois é olha ela ai.
“..As with many of the utilities that deal with filenames, the output of ls for multiple files or in one of the long listing formats must be used carefully on systems where filenames can contain embedded white space. Systems and system administrators should institute policies and user training to limit the use of such filenames.

The number of disk blocks occupied by the file that it reports varies depending on underlying file system type, block size units reported and the method of calculating the number of blocks. On some file system types, the number is the actual number of blocks occupied by the file (counting indirect blocks and ignoring holes in the file); on others it is calculated based on the file size (usually making an allowance for indirect blocks, but ignoring holes). ..” http://opengroup.org/onlinepubs/007908775/xcu/ls.html

“… Normally the size is printed as a byte count without punctuation, but this can be overridden (*note Block size::). For example, `-h’ prints an abbreviated, human-readable count, and `–block-size=”‘1″‘ prints a byte count with the thousands separator of the current locale.
For each directory that is listed, preface the files with a line `total BLOCKS’, where BLOCKS is the total disk allocation for all files in that directory. The block size currently defaults to 1024 bytes, but this can be overridden (*note Block size::). The BLOCKS computed counts each hard link separately; this is arguably a deficiency. …” http://www.examplenow.com/info/ls

Mas se o interesse era mesmo somente listar os arquivos e tal. Você poderia ter utilizado também o
# find . -ls | more

Dhcp 2003 e AD 2008 erro

um AD 2008 e um DHCP no 2003
não consegue autorizar o DHCP, no 2003 diz que ele não consegue contactar o active directory, o que fazer?

Vamos a checagem:
o 2003 já estava na rede antes do 2008?
no manage authorized servers o servidor esta lá?
se você clicar com botão direito nele da a opção “unauthorize” esta disponível?
visualmente a seta esta vermelha?
seu SCOPE esta Ativo?
o serviço esta “estartado”?
dica, olhe o event viewer, “stop” o serviço e olhe lá se ele parou, depois “start” olha lá novamente o erro.
possível mensagem do event viewer no 2003
“The DHCP service failed to see a directory server for authorization”
no 2008 não tem erro?
verifique se o servidor 2003 aparece no dns e esta pingando e o time esta igual.
o 2003 aparece no dns do 2008?
o ip fixo do 2003 tah apontando para o ip correto, principalmente o dns?

execute ip config /displaydns
depois um
ip config / registerdns isso no 2003.
aguarde o ok e a informação que erros serão informados em ate 15 minutos no event viewer
veja se lá no 2008 se apareceu a margarida.
