Subject: [PATCH] rpath hack
|
||||||
|
|
||||||
|
Normally, rpath is undesirable. But for the X server we _know_ we need
|
||||||
|
Mesa's libGL, which will always be in %{_libdir}, and not any third-party
|
||||||
|
libGL that may be configured using ld.so.conf.

Subject: [PATCH] Fix typo in mirror monitor detection
|
||||||
|
|
||||||
|
Bug introduced in fb561eb but still somehow passed manual testing.
|
||||||
|
Resulted in some stray reads off the end of the stack, which were
|
||||||
|
hopefully harmless.

Subject: [PATCH] SELinux: use /root/.vnc in file context specification
|
||||||
|
|
||||||
|
Instead of HOME_ROOT/.vnc, /root/.vnc should be used
|
||||||
|
for user root's home to specify default file context
|
||||||
|
as HOME_ROOT actually means base for home dirs (usually /home).

# The vncserver service unit file
|

|
#
|
||||||
|
# Quick HowTo:
|
||||||
|
# 1. Copy this file to /etc/systemd/system/xvnc@.service
|
||||||
|
# 2. Copy xvnc.socket to /etc/systemd/system/xvnc.socket
|
||||||
|
# 3. Run `systemctl daemon-reload`
|
||||||
|
# 4. Run `systemctl enable xvnc.socket`
|
||||||
|
#
|
||||||
|
# DO NOT RUN THIS SERVICE if your local area network is
|
||||||
|
# untrusted! For a secure way of using VNC, you should
|
||||||
|
# limit connections to the local host and then tunnel from
|
||||||
|
# the machine you want to view VNC on (host A) to the machine
|
||||||
|
# whose VNC output you want to view (host B)
|
||||||
|
#
|
||||||
|
# [user@hostA ~]$ ssh -v -C -L 590N:localhost:590M hostB
|
||||||
|
#
|
||||||
|
# this will open a connection on port 590N of your hostA to hostB's port 590M
|
||||||
|
# (in fact, it ssh-connects to hostB and then connects to localhost (on hostB).
|
||||||
|
# See the ssh man page for details on port forwarding)
|
||||||
|
#
|
||||||
|
# You can then point a VNC client on hostA at vncdisplay N of localhost and with
|
||||||
|
# the help of ssh, you end up seeing what hostB makes available on port 590M
|
||||||
|
#
|
||||||
|
# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.
|
||||||
|
#
|
||||||
|
# Use "-localhost" to prevent remote VNC clients connecting except when
|
||||||
|
# doing so through a secure tunnel. See the "-via" option in the
|
||||||
|
# `man vncviewer' manual page.
