#
# TCP Ports
#
# Ok, when aMule crash and you restart it too quickly you have
# a LOWID (and this is not good!!!) because the port is not well closed.
# A good solution is to change the TCP port.
# Here you can specify 2 TCP Ports and the script will switch between them
# (remember to configure your firewall to open and forward both ports)
#
TCPPORT1=4001
TCPPORT2=4010

# VNC configuration
#
# VNCDISPLAY: server display number
#
# If you set VNCDISPLAY then aMule will try to connect on the selected server
# display. When not set it connect to :0 (default X display). This var is
# only useful when you use VNC or X on another display.
# If you don't know what VNC is, you probably don't need it, so you can
# safely comment the following line!

I run this every hour with a cronjob (crontab --help for info)
and it do fine . . . (take a look at the path for amule in the script)
and if your system language isn't english you have to change "Restart the Programm" commands !!!!
Hope this can help
