…dreaming, what will be happened in the next exam week…

So you have trouble installing Maple 10 on your ubuntu because *it fails to your detect Host ID*

The problem is because the license manager used in the Maple can only use eth0 (the network device on your notebook). If you are like me, that has notebook with WIFI, ubuntu may not assign your network card to eth0. My notebook was using eth3 before, because I have moved my hard disk to my current notebook. So when you install Maple, it fails to detect your Host ID (your Host ID is based on your eth0 MAC Address).

Now you have to find out which ethernet card number you are using right now, using ifconfig

romi@mesintik:~$ ifconfig
eth0 Link encap:Ethernet HWaddr 00:01:4A:XX:YY:ZZ
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)

eth3 Link encap:Ethernet HWaddr 00:0E:35:XX:YY:ZZ
inet addr:192.168.1.33 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::20e:35ff:fefd:3f1b/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:221396 errors:0 dropped:0 overruns:0 frame:0
TX packets:138753 errors:0 dropped:0 overruns:0 carrier:1
collisions:0 txqueuelen:1000
RX bytes:287095962 (273.7 MB) TX bytes:18427810 (17.5 MB)

Now, for example I need to use eth3 to be eth0.

So, fire up your text editor (I use gedit), and using sudo command:

sudo gedit /etc/udev/rules.d/70-persistent-net.rules

The file contents will look like this:

# This file maintains persistent names for network interfaces.
# See udev(7) for syntax.
#
# Entries are automatically added by the 75-persistent-net-generator.rules
# file; however you are also free to add your own entries.

# PCI device 0x8086:0x1043 (ipw2100)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:04:23:XX:YY:ZZ", NAME="eth1"

# PCI device 0x8086:0x1068 (e100)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:01:4a:XX:YY:ZZ", NAME="eth0"

# PCI device 0x8086:0x4220 (ipw2200)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:0e:35:XX:YY:ZZ", NAME="eth3"


Because we need to change eth3 (HWaddr 00:0E:35:XX:YY:ZZ) to eth0, so you need to edit to change NAME="eth3" to NAME="eth0" and change the previous eth0 to ethX where X can be any number.

So the new file is like below:

# PCI device 0x8086:0x1043 (ipw2100)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:04:23:XX:YY:ZZ", NAME="eth1"

# PCI device 0x8086:0x1068 (e100)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:01:4a:XX:YY:ZZ", NAME="eth3"

# PCI device 0x8086:0x4220 (ipw2200)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:0e:35:XX:YY:ZZ", NAME="eth0"

Now, reboot the system and then start Maple installer and proceed as usual.

Now after that, if you enable Compiz and then Maple screen is only display grey-blank-window, you can make a fix as follows:

First, you need to install java-sun-6 from your Synaptic Package Manager (in the System -> Administration)

Edit a maple file that is /path/to/maple/bin/maple:

Find string MAPLE_JRE_BIN and change it to this

MAPLE_JRE_BIN="/usr/lib/jvm/java-6-sun/bin/"

(Maybe you need to adjust it according with your java installation)

Save and then run xmaple.

Voila!
