-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Marcelo, os serviços inet ouve conexões e inicia o servidor especifico para cada serviço. Já tive problemas parecidos com o seu e o que fiz foi alterar a linha
tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /srv/tftp para tftp dgram udp wait.100 nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /srv/tftp ou ainda tftp dgram udp nowait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /srv/tftp Este numero 100 (pode ser maior ou menor) indica quantas instâncias serão abertas e ficaram ouvindo por conexões. Portanto, serve até como um limitador de conexões. Teste e reporte na dup se tiver sucesso.
