redhat5开启xManager方法.doc

一、 XMANAGER 连接到REDHAT AS 5 需要修改的地方。配置文件位置：/usr/share/gdm/default.conf修改配置选项：xdmcp段DisplaysPerHost=101、Enable=true/257行2、Port=177/284行security段3、AllowRemoteRoot =true/214行替换原来最后一行为/etc/inittab文件最后一行为x:5:respawn:/usr/bin/gdm使用命令gdm -restart重启gdm；查看gdm监听端口开启成功;netstat -nltpu | grep 177xmanager连接不上，可能关闭RedHat防火墙service iptables stop二、 如果允许Root用户连接到XMANAGER 需要修改以下内容：# vi /usr/share/gdm/defaults.confsecurity# Allow root to login. It makes sense to turn this off for kiosk use, when# you want to minimize the possibility of break in.AllowRoot=true# Allow login as root via XDMCP. This value will be overridden and set to# false if the /etc/default/login file exists and contains# CONSOLE=/dev/login, and set to true if the /etc/default/login file exists# and contains any other value or no value for CONSOLE.AllowRemoteRoot=true# This will allow remote timed login.AllowRemoteAutoLogin=false# 0 is the most restrictive, 1 allo#vi /etc/securetty.tty2tty3tty4tty5tty6tty7tty8tty9tty10tty11pts/0pts/1pts/2pts/3pts/4添加这一些。# vi /etc/pam.d/login#%PAM-1.0#auth user_unknown=ignore success=ok ignore=ignore default=bad pam_securetty.soauth include system-authaccount required pam_nologin.soaccount include system-authpassword include system-auth# pam_selinux.so close should be the first session rulesession required pam_selinux.so closesession include system-authsession required pam_loginuid.sosession optional pam_console.so# pam_selinux.so open should only be followed by sessions to be executed in the user contextsession required pam_selinux.so opensession optional pam_keyinit.so force revoke#vi /etc/pam.d/remote#%PAM-1.0#auth required pam_securetty.soauth include system-authaccount required pam_nologin.soaccount include system-authpassword include system-auth# pam_selinux.so close should be the first session rulesession required pam_selinux.so closesession include system-authsession required pam_loginuid.sosession optional pam_console.so# pam_selinux.so open should only be followed by sessions to be executed in the user contextsession required pam_selinux.so opensession optional pam_keyinit.so force revoke#vi /etc/xinetd.d/krb5-telnet/or telnet# default: on# description: The telnet server serves telnet sessions; it uses # unencrypted username/password pairs for authentication.service teln
