配置RedHat telnet的方法

telnet在很多系统中都有所应用。今天我们就来讲解一下配置RedHat telnet服务的具体操作。由于RedHat AS3/4使用kerberos5认证,默认telnet服务无法行root登录,所以需要重新安裝telnet-server进行配置,具体步骤如下:

配置RedHat telnet服务1、下载安裝telnet-server.

配置RedHat telnet服务2、修改/etc/xinetd.d/telnet ,将disable=yes修改为no,之后将/etc/xinetd.d/krb5-telnet中disable=no修改为yes(让服务重启后,按设定值设置)

QUOTE:[root@ika xinetd.d]# cat /etc/xinetd.d/telnet

# 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

}

配置RedHat telnet服务3、修改/etc/pam.d/login文件,将第二行"auth required pam_securetty.so"注释掉

QUOTE:[root@ika pam.d]# cat login

#%PAM-1.0

#auth required /lib/security/pam_securetty.so

auth required /lib/security/pam_stack.so service=system-auth

auth required /lib/security/pam_nologin.so

account required /lib/security/pam_stack.so service=system-auth

password required /lib/security/pam_stack.so service=system-auth

session required /lib/security/pam_stack.so service=system-auth

session optional /lib/security/pam_console.so

配置RedHat telnet服务4、修改/etc/securetty文件,添加登录的tty,如pts/0,pts/1,pts/2.......

QUOTE:[root@RN031 etc]# cat securetty

pts/0

pts/1

pts/2

vc/1

vc/2

vc/3

vc/4

配置RedHat telnet服务5、重启xinetd:service xinetd restart.
