I have just reinstalled FreeBSD from the CD burned from
ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/4.5/4.5-install.iso
The problem remained :(( I did not touch any file including /etc/*
I did not change anything after installation.
`ping some.host.net` works fine.
`ftp some.host.net` and `telnet some.host.net any-port` both start
working only after 4 queries of AAAA records time out.
So, Greg, I followed your advice, I have got standard /etc/* from the
distribution now. ping resolves domain names as expected, but not ftp
and telnet. Why? Have anybody ever heard of such a trouble or am I the
only man on the Earth experiencing it? :-(
Another thing: when my brand-new FreeBSD 4.5 Release installation boots,
I see among others such a message:
Starting standard daemons: inetd cron sshd usbd sendmail
the cursor stops after `sendmail' and it takes boot process exactly
2 min 30 seconds to go further. Looks like two 75-second timeouts
(2 series of 5+10+20+40 s timeouts).
If I mis-installed FreeBSD, what could I have done wrong? I am loosing
hope to have a chance to enjoy FreeBSD, so please help me. Many thanks
in advance for any clue, advice or explanation.
