# inittab       This file describes how the INIT process should set up

# Default runlevel. The runlevels used by RHS are:
#   0 - halt (Do NOT set initdefault to this)
#   1 - Single user mode
#   2 - Multiuser, without NFS (The same as 3, if you do not have networking)
#   3 - Full multiuser mode
#   4 - unused
#   5 - X11
#   6 - reboot (Do NOT set initdefault to this)

# XDMCP is the protocol that allows remote login.  If you want to log into
# gdm remotely (I‘d never turn this on on open network, use ssh for such
# remote usage that).  You can then run X with -query <thishost> to log in,
# or -indirect <thishost> to run a chooser.  Look for the ‘Terminal‘ server
# type at the bottom of this config file.
[xdmcp]
# Distributions: Ship with this off.  It is never a safe thing to leave
# out on the net.  Setting up /etc/hosts.allow and /etc/hosts.deny to only
# allow local access is another alternative but not the safest.
# Firewalling port 177 is the safest if you wish to have xdmcp on.
# Read the manual for more notes on the security of XDMCP.
Enable=true
# Honour indirect queries, we run a chooser for these, and then redirect
# the user to the chosen host.  Otherwise we just log the user in locally.

# How many times can a person log in from a single host.  Usually better to
# keep low to fend off DoS attacks by running many logins from a single
# host.  This is now set at 2 since if the server crashes then gdm doesn‘t
# know for some time and wouldn‘t allow another session.
#DisplaysPerHost=2
# The number of seconds after which a non-responsive session is logged off.
# Better keep this low.
#PingIntervalSeconds=15
# The port.  177 is the standard port so better keep it that way

# The first form tells xdm which displays to respond to itself.
# The second form tells xdm to forward indirect queries from hosts matching
# the specified pattern to the indicated list of hosts.
# The third form tells xdm to handle indirect queries using the chooser;
# the chooser is directed to send its own queries out via the broadcast
# address and display the results on the terminal.
# The fourth form is similar to the third, except instead of using the
# broadcast address, it sends DirectQuerys to each of the hosts in the list
#
# In all cases, xdm uses the first entry which matches the terminal;
# for IndirectQuery messages only entries with right hand sides can
# match, for Direct and Broadcast Query messages, only entries without
# right hand sides can match.
#

# *                                     #any host can get a login window

#
# To hardwire a specific terminal to a specific host, you can
# leave the terminal sending indirect queries to this host, and
# use an entry of the form:
#

#terminal-a     host-a

#
# The nicest way to run the chooser is to just ask it to broadcast
# requests to the network - that way new hosts show up automatically.
# Sometimes, however, the chooser can‘t figure out how to broadcast,
# so this may not work in all environments.
#

*               CHOOSER BROADCAST       #any indirect host can get a chooser

利用Xmanager Enterprise 5的passive显示远程linux主机图形化信息

问题描述: 最初的需求是,安装oracle数据(第一次安装都是图形化linxu进去一步步操作,后续发现可以命令静默安装不调用图形化,学习就是步步入深,方得始终),最初实现window弹出linux主机图形化是vncviewer实现的,然而vncserver设置相对繁琐亦有可能不成功! 行千里,始于足下! 问题解决: 看过经验丰富的操作,才发现调出图形化可以如此简单!利用xshell的企业版Xmanager的passive是远程linux图形化信息通过X11协议传输到互通windows上. 实验背
