I have updated my workstation to the 64-bit beta of Ubuntu (v. 9.04) Jaunty Jackalope. Installing the Adobe Flash (v. 10) plugin was easy.

Get the beta of the player from the bottom of the page at:

http://labs.adobe.com/downloads/flashplayer10.html

And then follow the directions at:

I restarted Firefox and everything worked fine — including videos at YouTube.

• 64-bit Ubuntu Intrepid 8.10
• 2 x NIC
• Both configured via DHCP
• eth0 goes to a LAN (10.5.5.0/24)
• eth1 goes to the Internet.

Problem:

• When both NICs are up I can’t get to the Internet.
• The issue is that both DHCP clients were requesting default gateway info and so I had two default gateway entries in my routing table.

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.59.3.0 * 255.255.255.0 U 0 0 0 eth1
10.5.5.0 * 255.255.255.0 U 0 0 0 eth0
192.168.122.0 * 255.255.255.0 U 0 0 0 vnet0
link-local * 255.255.0.0 U 1000 0 0 eth0
default 10.59.3.1 0.0.0.0 UG 100 0 0 eth1
default 10.5.5.1 0.0.0.0 UG 100 0 0 eth0

Solution:

• Modify the /etc/dhcp3/dhclients.conf file.
• Add an interface section for each NIC and don’t request a router for the LAN-side.

interface “eth0″ {
request subnet-mask, broadcast-address, time-offset, domain-name-servers,
domain-name, domain-search, host-name, interface-mtu;
}

interface “eth1″ {
request subnet-mask, broadcast-address, time-offset, routers,
domain-name, domain-search, host-name,
netbios-name-servers, netbios-scope, interface-mtu;
}

note: I am also using my own DNS server so I don’t request one from eth1.

I recently installed Ubuntu Intrepid (8.10) 64-bit Desktop and wanted to get Java working in Firefox 3. I had to do several things to get it working.

These are my steps, to the best of my recollection, at this point. I will try to go back and test them on a clean box and tidy them up asap.

Summary:

• Remove icedtea6-plugin
• Remove openjdk-6-jdk
• Remove gcj
• Install sun-java6-jdk
• Install sun-java6-bin
• Install jdk-6u12-linux-x64.bin (I installed to /usr/lib/jvm/
• Use update-alternatives/galternatives and set all the java related links to the proper locations
• ln -s /usr/lib/jvm/jdk1.6.0_12/jre/lib/amd64/libnpjp2.so  /usr/lib/firefox-3.0.7/plugins/libnpjp2.so
