hosts.deny文件：#
# hosts.deny        This file describes the names of the hosts which are
#                *not* allowed to use the local INET services, as decided
#                by the '/usr/sbin/tcpd' server.
#
# The portmap line is redundant, but it is left to remind you that
# the new secure portmap uses hosts.deny and hosts.allow.  In particular
# you should know that NFS uses portmap!

Answer 1

你给出passwd,和shadow名优多大的用处的。
先确定你的telnet 有没有启动？
netstat -natup 贴出这个命令的输出

Answer 2

RH9。0吧，LINUX最新才2。X

Answer 3

4.1

Answer 4

red hat linux telnet 已经启动。
Red Hat Linux release 8.0 (Psyche)
Kernel 2.4.18-14 on an i586
login: szapp
Password:
Login incorrect

我是远程访问主机，所以netstat -natup无法实现。

Answer 5

到底有没有解决办法？
