WiFi was installed in the whole area. Waiters were carrying iPhones instead of the regular pen and paper to take the orders. They have built in an customize application to run on them to take the orders as well as print them to a network printer near the counter.

Electronic gadgets being part of the common man shows the progress that India has made and about the economic reforms that it have undergone.

Technology for the masses …

Requirements: Migrate an existing instance of SYBYL from one machine to another, using the same license file.

The initial installation of SYBYL was being carried out, by the vendor itself (since it was in support) on RHEL 4, wherein they have done all the installation including support, creating the license etc. But since the machine in which it was installed is no longer functional, we had to urgently shift it to a new machine.

The migration process is as stated below:

1. Got a new machine and installed CentOS 5.6.
2. Created a new user `tripos`, since SYBYL uses are normal user for the installation.
3. Copy the license manager file from the old machine to the new one.
4. Open the license file and check for the name of the machine as well as the mac address. The line would look like this,

SERVER sybyl.example.com 000f2c3de043

From the above line you can see figure out that the old sever name was `sybyl.example.com` and the mac address is `00:0f:2c:3d:e0:43`
5. Change the hostname of your new computer using the `hostname` command. You need to be root user while using this command,

hostname sybyl.example.com

6. Change the hardware Ethernet address of your new machine to that of your old one. You need to be the root user while using the following,

ifconfig eth0 hw ether 00:0f:2c:3d:e0:43 up

7. Copied all the 4 CD’s to the installation directory
8. Go inside CD1 and do the following,

sh install.sh

9. A GUI will pop up which will show your way to the next steps.
10. Path of the old license file.
11. In case you plan to have the other databases installed go on else click on exit after your basic installation.
12. Read the `ToDoList.txt` inside the `sybyl7.2` directory
13. Start the SYBYL license manager using the following commands,

cd trigo
- Enter: trigo -shell sybyl7.2
- Enter: su (enter root password when prompted)
cd $TA_LICENSE/bin/unix
cp ./triposlm.sh /etc/init.d/triposlm.sh
/etc/init.d/triposlm.sh -up
exit
exit

14. Once the license manager is started you can use the sybyl software. The binaries will be kept in sybyl7.2/bin/linux

Note: There might be errors, which might crop up while running sybyl. I have listed some of them,

Error 1: sybyl7.2/bin/linux/autoterm.exe: error while loading shared libraries: libXm.so.3: cannot open shared object file
Error 2: sybyl7.2/bin/linux/autoterm.exe: error while loading shared libraries: libGL.so.1: cannot open shared object file
Error 3: sybyl7.2/bin/linux/autoterm.exe: error while loading shared libraries: libGLU.so.1: cannot open shared object file
Error 4: sybyl7.2/bin/linux/autoterm.exe: error while loading shared libraries: libGLU.so.1: wrong ELF class: ELFCLASS64

As part of the solution 1,2 and 3 you need to install the following,

yum install openmotiff22 mesa-libGLU-6.5.1-7.8.el5.i386

Error 4 came up, since I was installing a 32 bit application on a 64 bit machine.

In case you have any more dependencies, you can use the following command,

yum whatprovides library-name


After all the installation is done, you are done good to run sybyl.

Before starting the installation, you need to install the following packages:
apt-get install build-essential psmisc linux-headers-`uname -r`

Installing the 32 bit version.

1. Download the 32 bit VMware server .tgz file from VMware.com
2. Extract the .tgz file.
3. Download the patch vmware-sever-2-0-2-32bit.tgz. Change the DIR in patch-vmware_2.6.3x.sh accordingly to your location of the VMware Server .tgz file.
4. ./patch-vmware_2.6.3x.sh / /vmware-server-distrib/lib/modules/source
5. cd / /vmware-server-distrib
6. ./vmware-install.pl

Installing the 64 bit version.

1. Download the 64 bit VMware server .tgz file from VMware.com
2. Extract the .tgz file.
3. Download the patch vmware-sever-2-0-2-64bit.tgz. Change the DIR in patch-vmware_2.6.3x.sh and the path in install-vmware-2.0.2.sh accordingly.
4. Patch is applied and the script will start the installation.

There might still be issues with SSL error being shown up. You can try doing the following,

1. mv /usr/lib/vmware/lib/libssl.so.0.9.8 /usr/lib/vmware/lib/libssl.so.0.9.8-unused
2. /etc/init.d/vmware restart

Firefox version 3.6 will not show up the management interface. It will show up a blank screen. You need to have version lower then this.

So, is there any open source software equivalent of cPanel. Yes, there is.

I myself have tried OpenPanel, which provides me a similar set of features as cPanel. You could very well try the others and install the one which meets your requirements.

Happy reselling

One of the counter guys restarted the system, and viola what I see, I can’t believe. It was giving an error and waiting for the root password to be typed in. “Press Ctrl D for maintenance”. I was very much astonished to see the retail shop shifting towards open source.

I did a bit of a search after coming back home, and I found out that it uses TPLinux on it’s POS and the solution has been brought from Wincor Nixdorf, a German based company. Future Group has claimed to have implemented around 6000 such units across its shops.

I have tried this in Ubuntu 10.04. I presume would work with all versions of GNU/Linux.

sudo apt-get install texlive tetex-extras tex4ht dvipng tex4ht
sudo texhash

The above will install the base software for Latex to work.

htlatex review_iisc_pkmadhu.tex “xhtml,ooffice” “ooffice/! -cmozhtf” “-coo -cvalidate”

Generate the OpenOffice file.

dvipng example.dvi
dvipos example.dvi

Convert to Portable Network Graphics and Postscript file.

Go to your buildout directory and run the following command:

Syntax:

bin/instance adduser

This will start Zope and Add a Manager user with the username and the password. You can now start your instance and log in with the user you just created. Note that if you try to create a user that already exists, it will fail silently, without giving any warning.

In case you are using the Unified Installer, you can use the following command,

Syntax:

bin/zopectl adduser

Before executing the command please make sure that you have your Zope started and working fine. Restart Zope after this and you should be able to login.

For older version of Zope, you need to create an emergency user which will help you in getting in the system, using the zpasswd.py script.

python [your zope]/bin/zpasswd.py access

While running the command it will ask for the username and the password along with the encryption that you need to do.

In case you are not able to locate the file, the easiest way would be to create the access file by using any editor with the following syntax,

username:password

Just restart Zope and you should be able to login again with the created username and password.

Please delete the file after you are down with the changing the password.

Moreover the same server had the slow mounting of NFS issue. Users would just wait for at least a minute after issuing the `ls` command and when login to GUI mode, it would just be in some state of hangover mode. I tried re-installing NFS kernel server along with updating the kernel, but still no help.

When doing a search somewhere it was mentioned that host needs to be identified. Since I was using IP’s, I thought it would not be a problem, but later on I found out that you need to make entries so that `idmapd` is able to locate it, some sort of a reverse DNS lookup. While restarting nfs-common you see two services being start, idmapd and statd. `idmapd` is the NFSv4 name mapping daemon. It provides functionality to the NFSv4 kernel client and server, to which it communicates via upcalls, by translating user and group IDs to names, and vice versa, while statd creates a file in /var/lib/nfs/statd/sm. When starting, it iterates through these files and notifies the peer rpc.statd on those machines. In case it does not find, it just takes it’s own time to mount it.

The same solved both the problems and user’s are also using it without any complaint.

The best part of the mall is the parking area which is free (as of now) with double decker parking for cars. Auto parking is also on their cards. When inquired about the double decker parking (which seems to be first in Bangalore) to one of the service person, he informed about it’s functionality. One slot is always free so that cars from top can be pulled down. A full bay has 5 slots in the bottom while 4 slots in the top wherein the top open 5th slot is used to navigate the other cars parked up, to be lowered down. It was amazing to see the technology that is being used.
