Central console for auth.log

Install Eterm and his Theme package.
Simply add the following startup program in your X initilization sequence :

Eterm -O0xqC --buttonbar 0 --scrollbar 0 --no-cursor -f lightgray --geometry 140x15+160+140 -F "-bitstream-bitstream vera sans mono-medium-r-normal-*-10-*-*-*-m-*-iso8859-1" --exec /usr/bin/tail -14f /var/log/auth.log

Use Eterm embedded theme "logger" for this.

Eterm -t logger
