配置RedHat telnet的方法
作者：佚名
文章中，我們對配置RedHat telnet的具體過程進(jìn)行了描述。希望大家通過文章內(nèi)容，能夠?qū)W會配置RedHat telnet的方法。
telnet在很多系統(tǒng)中都有所應(yīng)用。今天我們就來講解一下配置RedHat telnet服務(wù)的具體操作。由于RedHat AS3/4使用kerberos5認(rèn)證,默認(rèn)telnet服務(wù)無法行root登錄,所以需要重新安裝telnet-server進(jìn)行配置,具體步驟如下:
配置RedHat telnet服務(wù)1、下載安裝telnet-server.
配置RedHat telnet服務(wù)2、修改/etc/xinetd.d/telnet ,將disable=yes修改為no,之后將/etc/xinetd.d/krb5-telnet中disable=no修改為yes(讓服務(wù)重啟后,按設(shè)定值設(shè)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服務(wù)3、修改/etc/pam.d/login文件,將第二行"auth required pam_securetty.so"注釋掉
- 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服務(wù)4、修改/etc/securetty文件,添加登錄的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服務(wù)5、重啟xinetd:service xinetd restart.
