Linux - Mover arquivos baseados em uma data e criar pasta com mês e ano

Quando temos muitos arquivos em uma só pasta é necessário criar divisões por mês e ano, assim o acesso aos dados não fica lento.
Para fazer isso no linux você pode utilizar o script abaixo:

mes=$(date +%m)

ano=$(date +%Y)

caminhoDestino=/caminho/$ano/$mes

mkdir -p $caminhoDestino

#Move os arquivos mais velhos que 1 dia

find /caminhoOrigem -type f -mtime +1 -exec mv {} $caminhoDestino \;

Exchange - Listar limites

Para mostrar os limites do Exchange, como tamanho máximo de mensagem, anexo, etc utilize o comando abaixo:

Get-TransportConfig | Format-List MaxReceiveSize,MaxSendSize,MaxRecipientEnvelopeLimit

Windows - Mover arquivos baseados em uma data e criar pasta com mês e ano

É comum termos que gerar um arquivo de log ou copiar dados para uma pasta com o mês, dia e ano.

A sequencia abaixo cria variáveis de ambiente com o mes e ano, cria a pasta em logs com o ano e mes, depois usa o robocopy para mover os arquivos para lá.

set mes=%date:~3,2%

set ano=%date:~6,4%

set caminhoDestino=c:\logs\%ano%\%mes%\

if not exist %caminhoDestino% mkdir %caminhoDestino%

robocopy d:\logs %caminhoDestino% /MOVE

Wireshark - Dicas de filtros

Já precisei utilizar o wireshark e não sabia como filtrar o conteúdo até que achei as dicas abaixo de filtros:

• tcp.port eq 25 or icmp
• ip.src==192.168.0.0/16 and ip.dst==192.168.0.0/16
• tcp.window_size == 0 && tcp.flags.reset != 1
• ls_ads.opnum==0x09
• udp[8:3]==81:60:03
• eth.addr[0:3]==00:06:5B
• sip.To contains "a1762"
• http.request.uri matches "gl=se$"
• ip.addr == 10.43.54.65
• ip.src == 10.43.54.65 or ip.dst == 10.43.54.65
• ip.addr != 10.43.54.65
• ip.src != 10.43.54.65 or ip.dst != 10.43.54.65
• ! ( ip.addr == 10.43.54.65 )
• ! (ip.src == 10.43.54.65 or ip.dst == 10.43.54.65)
