thank you !
i just install the redhat 7.1 . but i can not telnet 21,23 port .
i changed xinetd.d/telnet and wu-ftp , "disable = yes". shutdown the ipchains
it looks ok!
but i now can not telnet my hosts 25 ports.
if i type " telnet localhost 25 " i can into it.
if i type " telnet hostname 25 " i get messages " connected refused "
i try changed /etc/sendmail.cf
and change "O DaemonPortOptions=Port=smtp,Addr=127.0.0.1 ,Name=MTA"
to " O DaemonPortOptions=Port=smtp,Addr=x.x.x.x ,Name=MTA "
and change "O Timeout.connect=1m " to "O Timeout.connect=10m "
IT IS NO USE .and i changed it back but when i telnet localhost 25 , it is
also FAILER !!!
why ??? thank you
