fala pessoal.. bl'z??
antes de mais nada... pesquisei sobre o assunto no google!
galera, estou montando um servidor NTP mas a coisa aqui não tá muito legal não...
Plataforma:
nunca vi um servidor deste rodando e as configurações do mesmo só vi pelas que achei na net...Citação:
Intel 486 DX/2 66MHz
28MB RAM
Slackware 10.2
Kernel 2.4.31
NTP 4.2.0
o problema é q rodo o servidor e o cliente não atualiza a hora..
a porta 123 está liberada no firewall..
segue minhas configurações do /etc/ntp.conf
os arquivos /etc/ntp/ntp.keys e /etc/ntp/ntp.drift estão com permissão 600 dono e grupo rootCitação:
restrict 127.0.0.1
restrict 10.0.0.0 mask 255.255.255.0 notrust nomodify notrap

controlkey 65535
logconfig all
#logfile /var/log/ntp.log
quando rodo o comando ntpd -d aparece o seguinte:
com relação ao arquivo drift percebi isso:Citação:

com o tcpdump rodando no servidor e executando o ntpdate servidor_ntp no cliente aparece o seguinte:Citação:

quem puder dar uma ajuda ae agradeço..Citação:
