WhatifLinux Personal Edition
LICENSED TO
MANAGE
JULIAN MOSS
WhatifLinux is a web-based software management system for computers
that run Linux. It will tell you if there are newer versions of packages to be
installed, let you see the dependencies and assess the effect of
uninstalling a package, and will alert you to important issues such as
security matters affecting the packages you use. The recently launched
Personal Edition is designed for users of standalone computers. We took a
look at it.
WhatifLinux consists of a Java-based agent that information it provides may not be accurate.

enough. In the end we chose the alternative
workaround, which was to complete this part of the
process with root privileges. Some people may be
uncomfortable with the idea of allowing a remote
system full access to the details of their system while
running as root.
Once installation has been completed you must
edit a script and also the crontab file, to ensure that

may find this a bit difficult, and there is a risk of
them messing up an important system file. Of
course, you can simply start the agent manually
when needed and stop it when finished. This is
probably a good idea if you use a dial-up Internet
connection as we found that connections were
regularly opened whilst the agent was running.
Once an agent is running you can log on at

SOFTWARE MANAGEMENT ON TEST
www.whatiflinux.com using your email address and
password and start the WhatifLinux Console. The
server connects to the agent and displays an
alphabetically indexed list of all the RPM packages
installed on your system. After selecting a package
from the list you can view details about it, including
a full list of the package contents, dependencies,
known conflicts and any alerts. You can also see if
there would be any undesirable effects if you
uninstalled the package and find out if there are any
newer versions of it.
In our tests the list of newer packages seemed
not always to be accurate. For example, all the
newer versions of wine listed appeared older than
the one we had installed. Version 0.60 of the mail
client Mahogany was shown as available although
we could find no trace of its release at the time of
testing either by using rpmfind or by looking on the
developers web site.
If you select one of the newer versions of a
package listed by WhatifLinux you can view the
possible conflicts and unsatisfied dependencies that
might arise if you installed it. What you can t do,
unfortunately, is actually install it. This option is
apparently available in the Workgroup Edition,
which also claims to let you update packages
simultaneously on many computers across a
network. We consider it surprising that this facility
has been omitted from the Personal Edition as it is
probably the most useful feature for the ordinary
user and would be a significant incentive to
subscribe to the service.
The ability to be alerted of security problems,
updates, patches and other important issues
affecting the software you are running is another
benefit that will be especially useful for
administrators of web servers and other business
critical systems. The information provided online is
detailed, giving an explanation of the problem as
well as a recommended fix. Links are also provided
if you want more information. You don t have to
keep checking the WhatifLinux web site to get this
information in a timely fashion as you can have it
emailed directly to you as soon as it happens.
However, there s a price to pay. WhatifLinux
Personal Edition costs $49 a year and the question
most people will be asking is: is it worth it? After all,
a package manager such as rpm or one of its
graphical equivalents will let you install and uninstall
packages and help you avoid dependency problems
and conflicts. WhatifLinux goes further than this. It
