O Samba 4 \u00e9 um produto servidor multifuncional, que tamb\u00e9m oferece implementa\u00e7\u00e3o de servidor de arquivos, servi\u00e7o de impress\u00e3o e servidor de identifica\u00e7\u00e3o (winbind).          <\/p>\n<p>Principais altera\u00e7\u00f5es no Samba 4.14:  <\/p>\n<ul>\n<li class=\"l\"> O n\u00edvel VFS passou por uma moderniza\u00e7\u00e3o significativa. Por raz\u00f5es hist\u00f3ricas, o c\u00f3digo que implementava o servidor de arquivos <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/server\/dts-los-angeles\/\"   title=\"servidor\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3652\">servidor<\/a> estava vinculado ao tratamento de caminhos de arquivos, que tamb\u00e9m era utilizado para o protocolo SMB2, que foi convertido para usar descritores. No Samba 4.14.0, o c\u00f3digo que fornece acesso ao sistema de arquivos do servidor foi reestruturado para usar descritores de arquivos em vez de caminhos de arquivos. Por exemplo, foi utilizado o chamador fstat() em vez de stat() e SMB_VFS_FSTAT() em vez de SMB_VFS_STAT().\n<li class=\"l\"> A confiabilidade da publica\u00e7\u00e3o de impressoras no Active Directory foi aumentada e as informa\u00e7\u00f5es sobre impressoras transmitidas para o Active Directory foram ampliadas. Suporte para drivers de impressora do Windows em sistemas ARM64 foi adicionado.\n<li class=\"l\"> Foi disponibilizada a possibilidade de usar pol\u00edticas de grupo (Group Policy) para clientes Winbind. O administrador do Active Directory agora pode definir pol\u00edticas que alteram as configura\u00e7\u00f5es do sudoers ou adicionam a execu\u00e7\u00e3o peri\u00f3dica de tarefas via cron. Para habilitar a aplica\u00e7\u00e3o de pol\u00edticas de grupo para o cliente, a configura\u00e7\u00e3o 'apply group policies' deve ser inclu\u00edda no smb.conf. A aplica\u00e7\u00e3o das pol\u00edticas ocorre a cada 90-120 minutos. Em caso de problemas, \u00e9 poss\u00edvel desfazer as altera\u00e7\u00f5es com o comando 'samba-gpupdate --unapply' ou reaplic\u00e1-las com 'samba-gpupdate --force'. Para visualizar as pol\u00edticas que ser\u00e3o aplicadas ao sistema, pode-se usar o comando 'samba-gpupdate --rsop'.\n<li class=\"l\"> A exig\u00eancia de vers\u00e3o da linguagem Python foi aumentada. Para compilar o Samba, agora \u00e9 obrigat\u00f3ria a presen\u00e7a do Python na vers\u00e3o 3.6 ou superior. O suporte para compila\u00e7\u00f5es com vers\u00f5es mais antigas do Python foi descontinuado.\n<li class=\"l\"> No utilit\u00e1rio samba-tool, foram implementados recursos para gerenciar objetos no Active Directory (usu\u00e1rios, computadores, grupos). Para adicionar um novo objeto ao AD, agora \u00e9 permitido usar o comando 'add', al\u00e9m de 'create'. Para renomear usu\u00e1rios, grupos e contatos, h\u00e1 suporte para o comando 'rename'. Para desbloquear usu\u00e1rios, foi proposto o comando 'samba-tool user unlock'. Nos comandos 'samba-tool user list' e 'samba-tool group listmembers', foram implementadas as op\u00e7\u00f5es '--hide-expired' e '--hide-disabled' para ocultar contas de usu\u00e1rios expiradas ou desativadas.\n<li class=\"l\"> No componente CTDB, respons\u00e1vel pelo funcionamento das configura\u00e7\u00f5es de cluster, foi realizada uma limpeza de termos n\u00e3o politicamente corretos. Em vez de master e slave ao configurar NAT e LVS, foi sugerido usar 'leader' para se referir ao n\u00f3 principal no grupo e 'follower' para abranger os outros membros do grupo. O comando 'ctdb natgw master' foi substitu\u00eddo por 'ctdb natgw leader'. Para indicar que um n\u00f3 n\u00e3o \u00e9 o l\u00edder, em vez de 'slave-only', agora \u00e9 exibida a flag 'follower-only'. O comando 'ctdb isnotrecmaster' foi removido.  <\/ul>\n<p>Adicionalmente, foi fornecida uma explica\u00e7\u00e3o sobre os limites de aplica\u00e7\u00e3o da licen\u00e7a GPL, sob a qual o c\u00f3digo Samba \u00e9 distribu\u00eddo, aos componentes VFS (Virtual File System). A licen\u00e7a GPL exige a abertura sob as mesmas condi\u00e7\u00f5es de todas as obras derivadas. O Samba possui uma interface para conectar plugins, permitindo a chamada de c\u00f3digo externo. Alguns desses plugins s\u00e3o m\u00f3dulos VFS, que utilizam os mesmos arquivos de cabe\u00e7alho do Samba para a defini\u00e7\u00e3o da API, atrav\u00e9s da qual ocorre a chamada aos servi\u00e7os implementados no Samba, raz\u00e3o pela qual os m\u00f3dulos VFS do Samba devem ser distribu\u00eddos sob GPL ou uma licen\u00e7a compat\u00edvel.     <\/p>\n<p>A incerteza surge em rela\u00e7\u00e3o a bibliotecas de terceiros que s\u00e3o chamadas pelos m\u00f3dulos VFS. Em particular, foi expressa a opini\u00e3o de que nos m\u00f3dulos VFS podem ser utilizadas apenas bibliotecas sob GPL e licen\u00e7as compat\u00edveis. Os desenvolvedores do Samba esclareceram que as bibliotecas n\u00e3o chamam o c\u00f3digo do Samba atrav\u00e9s da API e n\u00e3o acessam estruturas internas, portanto, n\u00e3o podem ser consideradas como obras derivadas e n\u00e3o est\u00e3o sujeitas \u00e0 exig\u00eancia de serem fornecidas sob licen\u00e7as compat\u00edveis com a GPL.<br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=54738\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u043b\u0435\u043d \u0440\u0435\u043b\u0438\u0437 Samba 4.14.0, \u043f\u0440\u043e\u0434\u043e\u043b\u0436\u0438\u0432\u0448\u0438\u0439 \u0440\u0430\u0437\u0432\u0438\u0442\u0438\u0435 \u0432\u0435\u0442\u043a\u0438 Samba 4 \u0441 \u043f\u043e\u043b\u043d\u043e\u0446\u0435\u043d\u043d\u043e\u0439 \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0435\u0439 \u043a\u043e\u043d\u0442\u0440\u043e\u043b\u043b\u0435\u0440\u0430 \u0434\u043e\u043c\u0435\u043d\u0430 \u0438 \u0441\u0435\u0440\u0432\u0438\u0441\u0430 Active Directory, \u0441\u043e\u0432\u043c\u0435\u0441\u0442\u0438\u043c\u043e\u0433\u043e \u0441 \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0435\u0439 Windows 2000 \u0438 \u0441\u043f\u043e\u0441\u043e\u0431\u043d\u043e\u0433\u043e \u043e\u0431\u0441\u043b\u0443\u0436\u0438\u0432\u0430\u0442\u044c \u0432\u0441\u0435 \u043f\u043e\u0434\u0434\u0435\u0440\u0436\u0438\u0432\u0430\u0435\u043c\u044b\u0435 Microsoft \u0432\u0435\u0440\u0441\u0438\u0438 Windows-\u043a\u043b\u0438\u0435\u043d\u0442\u043e\u0432, \u0432 \u0442\u043e\u043c \u0447\u0438\u0441\u043b\u0435 Windows 10.
