Hi: /etc/securetty has nothing to do with IP addresses or ETH0, it's merely concerned with TTY devices (either /dev/ttyXX or /dev/pts/xx). If you want to restrict access to various IP addresses then use host.allow and host.deny, but this only works for blanket access to services like SSH , FTP, telnet, etc, and is not used to accept or reject particular users.
