Running 32bit applications on 64bit Ubuntu

Nalin — Tue, 17 May 2011 04:10:09 +0000

After upgrading to 64bit Ubuntu 11.04, I wasn’t able to get some applications to work and was getting a very cryptic error

nullin@null-in:/work$ p4
bash: /build/bin/p4: No such file or directory

Even though /build/bin/p4 exists, on running the command, the system was complaining that the file doesn’t exist. I soon realized these were 32 bit applications and to fix this, one just needs to install ia32-libs:

sudo apt-get install ia32-libs

After doing this, things starting working properly again:

nullin@null-in:/work$ p4
Perforce -- the Fast Software Configuration Management System.
p4 is Perforce's client tool for the command line.  Try:

VMware Workstation 7.1.4, Ubuntu 11.04 and Unity

Nalin — Wed, 27 Apr 2011 14:42:12 +0000

Three days back I installed Ubuntu 11.04 Beta onto my work machine. I tried getting Workstation to work but it kept crashing. In Unity session, it would start up and even start the VMs but would keep crashing on trying to switch to the VM console. In gnome session workstation would startup, switch to console session but crash while trying to move files in and out of the VM.

Version 7.1.3 has known issue with running in the new Unity session and v7.1.4 was supposed to fix this. Going by some comments online, it has seemed to fix it in many cases to. For me it just wasnt working. After looking around for a while I found a workaround on VMware community forums. For making VMware Workstation 7.1.4 with work with Ubuntu 11.04 in Unity Session, just start it from cli as follows:

$ export LD_PRELOAD=/usr/lib/vmware/lib/libglib-2.0.so.0/libglib-2.0.so.0
$ vmware

This fixes the glib related errors that were crashing the software and you can start using your VMs. See this forum thread for more information.

VMware Player and Ubuntu 8.10 keyboard mapping issues

Nalin — Thu, 13 Nov 2008 06:58:15 +0000

Yesterday I installed VMware Workstation 6.5 on my fresh install of Ubuntu 8.10. After powering on a Windows XP vm, I realized that I could not use the arrow keys properly. On hitting the left arrow key, start menu was being displayed and other arrow keys had similar issues. Also, using VMware player was completely impossible as ctrl-alt-del wasn’t working.

After searching around a bit I found that many others had faced similar issue. Apparently it is not a bug with VMware Workstation. Due to some updates to Ubuntu 8.10, the keyboard mappings were screwed up. I found good amount of information in the VMware communities forum.

To fix this issue, you simply need to run the following command,

echo 'xkeymap.nokeycodeMap = true' > ~/.vmware/config

and if VMware Player/Server/Workstation was running, just restart it.

You should then be good to go…

Static IP address on Ubuntu 8.10

Last Friday I upgraded my install from Ubuntu 7.04 to 8.10 Intrepid Ibex on my office workstation and I noticed that I was unable to assign static IP to the machine. After reboot the netmask was getting messed up and reset to 22. Look at this bug for more info.

So, I ditched the native ubuntu Network Manager and installed wicd which is another open source network manager that works with Ubuntu. But after configuring wicd with the static IP, I had another problem. Everytime I restarted the machine, I had to manually start the wicd network manager. Instead of trying anything more with wicd, I decided to ditch a network manager altogether and just configure the files myself.

So, to get the network working with static IP, first remove the network manager (Many people have said that it is not necessary, but I prefer to remove it as I wont be using it anyway):

sudo apt-get remove --purge network-manager

Then modify the /etc/resolv.conf with the dns servers and domain names:

search foo.bar.com bar.com nameserver 192.168.0.1 nameserver 192.168.0.2

Now, modify /etc/network/interfaces and add

auto eth0 iface eth0 inet static address 192.168.0.10 netmask 255.255.252.0 gateway 192.168.0.253

Now, just restart the networking:

sudo /etc/init.d/networking restart

Obviously, you should figure out the netmask, gateway and name servers before you start these steps.

This is all that you need to do to configure the machine with a static IP.

VMware player on Ubuntu 8.04 (Hardy Heron)

I recently upgraded my office computer from Gusty to Hardy and VMware player stopped working for me. I looked around a bit and found a nice step-by-step guide to get it up and running. Here are the steps:

cd /usr/lib/vmware/modules/source
cp vmmon.tar vmmon.tar.orig
sudo tar xvf vmmon.tar
cd vmmon-only/include/
sudo vi vcpuset.h
change line 74 from: #include ‚Äúasm/bitops.h‚Äù to: #include ‚Äúlinux/bitops.h‚Äù
rm vmmon.tar (return to the folder where you decompressed the tar file)
sudo tar cvf vmmon.tar vmmon-only/
sudo rm -rf vmmon-only/
sudo vmware-config.pl

To save you some time, I have uploaded the fixed vmmon.tar, that you can use to replace the original with. Just untar the vmplayer package, download vmmon.tar and cp it to /lib/modules/source/ and then start the installation process.

This same process should work for VMware Server and Workstation as well.
