VNC

setup VNC server on CC7

Keep getting errors using ssh tunnel, can't be reproduced by CERN IT ticket
channel 3: open failed: administratively prohibited: open failed

yum install tigervnc-server

open firewall port, port corresponds to the screen number, e.g. 5903 for :3

firewall-cmd --permanent --zone=public --add-port=5903/tcp
firewall-cmd --reload

To resolve "authentication is required to create a color profile" problem, add file

/etc/polkit-1/localauthority/50-local.d/color.pkla
with

[Allow colord for all users]
Identity=unix-user:*
Action=org.freedesktop.color-manager.create-device;org.freedesktop.color-manager.create-profile;org.freedesktop.color-manager.delete-device$
ResultAny=yes
ResultInactive=yes
ResultActive=yes

setup VNC server on Lubuntu 17.04 (BDAQ PCs)

apt install tightvncserver
or
apt install vnc4server

open firewall port, port corresponds to the screen number, e.g. 5903 for :3

ufw allow 5903/tcp
ufw reload

To resolve grey screen upon connection, modify file

~/.vnc/xstartup
with

#!/bin/sh
xsetroot -solid grey
export XKL_XMODMAP_DISABLE=1
#autocutsel -fork
openbox &
lxpanel &
/usr/bin/lxsession -s Lubuntu &

Access VNC session from Ubuntu

vncviewer HOSTNAME.cern.ch:SCREEN -via USERNAME@lxplus.cern.ch

matplotlib on CentOS7

yum repo is at v1.1.4 or so, therefore use pip

sudo yum install python-pip
sudo pip install --upgrade pip==9.0.1
sudo python -m pip install matplotlib

My Personal Preferences

  • Show tool-tip topic info on mouse-over of WikiWord links, on or off:
    • Set LINKTOOLTIPINFO = off

  • Preference for the editor, default is the WYSIWYG editor. The options are raw, wysiwyg:
    • Set EDITMETHOD = raw

  • More preferences TWiki has system wide preferences settings defined in TWikiPreferences. You can customize preferences settings to your needs: To overload a system setting, (1) do a "raw view" on TWikiPreferences, (2) copy a Set VARIABLE = value bullet, (3) do a "raw edit" of your user profile page, (4) add the bullet to the bullet list above, and (5) customize the value as needed. Make sure the settings render as real bullets (in "raw edit", a bullet requires 3 or 6 spaces before the asterisk).
