Xmanager3.0连接配置RedHat Enterprise Linux 5
我们这里采用Xmanager3.0连接配置RedHat Enterprise Linux 5进行图形界面导航安装,需要在linux上面进行一些配置文件的修改,具体如下。
环境介绍
服务器:RedHat Enterprise Linux 5.0
客户端:xmanager3.0英文版
服务器相关配置文件介绍
1./usr/share/gdm/defaults.conf----GNOME管理默认的配置文件
2./etc/inittab---init进程的主配置文件
3./etc/gdm/custom.conf---GNOME的自定义配置文件
步骤如下:
1.改变defaults.conf文件权限,默认是只读
chmod 700 /usr/share/gdm/defaults.conf
2.做如下配置---编辑/usr/share/gdm/defaults.conf
将以下内容添加到defaults.conf后面:
Enable=true
DisplaysPerHost=10
Port=177
AllowRoot=true
AllowRemoteRoot=true
AllowRemoteAutoLogin=false
3.做如下配置---编辑/etc/gdm/custom.conf
[xdmcp]
Enable=1
4.做如下配置---编辑/etc/inittab,注意:不要修改原来设置,在最后新增一行如下记录
x:5:respawn:/usr/sbin/gdm
5.配置防火墙,注意,如果防火墙已经关闭,这个可以不用设置。
iptables -A INPUT -p udp --dport 177 -j ACCEPT
6.重新加载GNOME桌面配置
init 3 或者 init 5
设置到这里Xmanager3就可以连接到服务器了,但是不能使用root用户来登录。要是想让root用户来登录还需要做如下设置。
1. 修改/usr/share/gdm/defaults.conf文件
。。。。。。。
[security]
# Allow root to login. It makes sense to turn this off for kiosk use, when
# you want to minimize the possibility of break in.
Vi
# 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 (说明,将这行修改成true)
# This will allow remote timed login.
AllowRemoteAutoLogin=false
# 0 is the most restrictive, 1 allo
………
2. 修改 /etc/securetty,在文件底部添加红色部分
......
tty2
tty3
tty4
tty5
tty6
tty7
tty8
tty9
tty10
tty11
pts/0
pts/1
pts/2
pts/3
pts/4
3. 修改/etc/pam.d/login
#%PAM-1.0
#auth [user_unknown=ignore success=ok ignore=ignore default=bad] pam_securetty.so (将这行注释掉)
auth include system-auth
account required pam_nologin.so
account include system-auth
password include system-auth
# pam_selinux.so close should be the first session rule
session required pam_selinux.so close
session include system-auth
session required pam_loginuid.so
session optional pam_console.so
# pam_selinux.so open should only be followed by sessions to be executed in the user context
session required pam_selinux.so open
session optional pam_keyinit.so force revoke
~
4. 修改/etc/pam.d/remote
#%PAM-1.0
#auth required pam_securetty.so(将此行注释掉)
auth include system-auth
account required pam_nologin.so
account include system-auth
password include system-auth
# pam_selinux.so close should be the first session rule
session required pam_selinux.so close
session include system-auth
session required pam_loginuid.so
session optional pam_console.so
# pam_selinux.so open should only be followed by sessions to be executed in the user context
session required pam_selinux.so open
session optional pam_keyinit.so force revoke
~
5. 修改/etc/xinetd.d/krb5-telnet
# default: on
# description: The telnet server serves telnet sessions; it uses \
# unencrypted username/password pairs for authentication.
service telnet
{
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID
disable = no(将此行中的yes修改成no)
}
改完后一定要记住 关闭 防火墙
service iptables stop
客户端Xmanager3设置
