开发板UT-S3C6410 telnet Linux主机的详细设置【友坚资料库】

以下是开发板UT-S3C6410 telnet  Linux主机的详细设置，应通过初次验证，请大家指教。www.urbetter.com
1.关于telnet命令的相关信息
[root@urbetter /]# telnet --help
BusyBox v1.13.3 (2009-03-25 15:48:45 CST) multi-call binary
Usage: telnet [-a] [-l USER] HOST [PORT]
Connect to telnet server
Options:
        -a      Automatic login with $USER variable
        -l USER Automatic login as USER
2.开发板telnet登录到其他提供了telnet服务器的主机
---确认开发板的ip地址，确认开发板能连接Internet
   ifconfig
   ping 内网的ip     ；ping 外网的ip
---设置路由ip：route add default gw 192.168.1.1
---登录：telnet 202.112.7.137
----------------------------------------------------------------------------------------------------------------------
3.开发板设置好网络，登录Internet
---设置网关:route add default gw 192.168.1.1(根据实际情况设定)
---确认连通Internet:ping 202.112.17.137
---设置域名解析服务器:
   查看你pc机上的DNS服务器的ip地址 202.96.128.96
   vim /etc/resolv.conf  添加 nameserver 202.96.128.96
   或者rm /etc/resolv.conf ;touch /etc/resolv.conf;
       echo nameserver 202.96.128.96 >> /etc/resolv.conf
-------------------------------------------------------------
4.开发板登录Linux主机
4.1Linux主机安装telnet服务
   sudo apt-get install xinetd telnetd
   修改配置
　 sudo vi /etc/inetd.conf并加入以下一行
   telnet stream tcp nowait telnetd /usr/sbin/tcpd  /usr/sbin/in.telnetd

   4.2sudo vi /etc/xinetd.conf并加入以下内容：
# Simple configuration file for xinetd
#
# Some defaults, and include /etc/xinetd.d/
defaults
{
# Please note that you need a log_type line to be able to use log_on_success
# and log_on_failure. The default is the following :
# log_type = SYSLOG daemon info
instances = 60
log_type = SYSLOG authpriv
log_on_success = HOST PID
log_on_failure = HOST
cps = 25 30
}

includedir /etc/xinetd.d
----------------------------------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------------------------------
4.3sudo vi /etc/xinetd.d/telnet并加入以下内容：
# default: on
# description: The telnet server serves telnet sessions; it uses
# unencrypted username/password pairs for authentication.
service telnet
{
disable = no
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID
}

5. 重启机器或重启网络服务sudo /etc/init.d/xinetd restart

6. 使用TELNET客户端远程登录；
   ifconfig -a   显示本机地址。
