用ubuntu好久了,就是不知道怎么用telnet服务。现在弄好了,整理一下资料,供大家学习参考。
1、安装xinetd 以及telnetd
liceven@liceven-laptop:~$ sudo apt-get install xinetd telnetd 获取:1 http://ubuntu.cn99.com feisty/main xinetd 1:2.3.14-1ubuntu1 [135kB] 获取:2 http://ubuntu.cn99.com feisty/universe telnetd 0.17-35ubuntu1 [42.0kB] 下载 177kB,耗时 7s (25.2kB/s) 选中了曾被取消选择的软件包 xinetd。 (正在读取数据库 ... 系统当前总共安装有 123141 个文件和目录。) 正在解压缩 xinetd (从 .../xinetd_1%3a2.3.14-1ubuntu1_i386.deb) ... 选中了曾被取消选择的软件包 telnetd。 正在解压缩 telnetd (从 .../telnetd_0.17-35ubuntu1_i386.deb) ... 正在设置 xinetd (2.3.14-1ubuntu1) ... Stopping internet superserver: xinetd. 增加 `diversion of /etc/init.d/inetd to /etc/init.d/inetd.real by xinetd' Starting internet superserver: xinetd.
正在设置 telnetd (0.17-35ubuntu1) ... --------- IMPORTANT INFORMATION FOR XINETD USERS ---------- The following line will be added to your /etc/inetd.conf file:
telnet stream tcp nowait telnetd /usr/sbin/tcpd /usr/sbin/in.telnetd
If you are indeed using xinetd, you will have to convert the above into /etc/xinetd.conf format, and add it manually. See /usr/share/doc/xinetd/README.Debian for more information. -----------------------------------------------------------

2、配置文件
A。 /etc/
inetd.confliceven@liceven-laptop:~$ cat /etc/inetd.conf (如果存在就不需要了)
telnet stream tcp nowait telnetd /usr/sbin/tcpd /usr/sbin/in.telnetd
|
B. 修改/etc/xinetd.conf
root@liceven-laptop:/etc# cat xinetd.conf
# 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
(插入红色部分)instances = 60 log_type = SYSLOG authpriv log_on_success = HOST PID log_on_failure = HOST cps = 25 30 }
includedir /etc/xinetd.d
C。/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;
