[CentOS-pt-br] Compartilhamento morrendo :(

Terça Julho 17 16:50:51 EDT 2012

velhim me metendo no meio da conversa. 

1 ela esta com o dhcpd ativo ? 

2 somente o samba cai ? (vc continua logado sem problemas via ssh ?) 

eu tive um problema similar em um cliente e o prob todo era a placa de rede. 

outro detalhe tbm que pode ocorrer e o switch qual modelo vc esta usando ? e jah conseguiu ver se tem alguma maquina tagarelando na rede ? da uma olhada no switch e veja se o bixim esta muito frenetico. 

esse server que vc esta usando ele esta como all in one ? tipo firewall samba dhcp dns e tudooo mais ?

Verifique o comando dmesg e o arquivo /var/log/messages.
