Packagekit Error

With the latest update on my Fedora 10(F10) I started getting this error when ever I wanted to use the gnome package kit (I was able to use yum though):
failed to get a TID: A security policy in place prevents this sender from sending this message to this recipient, see message bus configuration file (rejected message had interface ”org.freedesktop.PackageKit.Transaction” member ”SetLocale” error name ”(unset)” destination ”org.freedesktop.PackageKit”) (0)

I searched couple of forums but did not find any good resource on what was happening. Finally I decided to rollback Packagekit and dbus. And Yahoooooooooooo, it started working again.

Color in grep output to distinquish the matching entries

Most of the times I end up spending a lot of time to look for the string in the grep output when I do a search. This is quite frustrating and thus I looked at the options for grep command that would make my life easier and there definately is something. Here it is:

export GREP_COLOR=”5;36”

But for this to work you would still need to give the ”–color=auto” option in the grep command. There are two ways to do this, create a alias for grep as ”grep –color=auto” or specify the same in GREPOPTIONS.

Damn Vulnerable Linux – DVL review

Today morning I got a chance to look at one of the other less commonly known Linux Distribution and out of the line distribution, very good for Learning purposes. The distribution is known as DVL (Damn Vulnerable Linux). As the name suggest this is for people looking at developing their skills in Security and Penetration testing. Quite a lot of good and interesting tools are included. More is left for users to experiment but I definately liked the distribution.

For stopping social abuse I would personally be montoring the accounts thus created and you would need to send a mail to gallery@amit-agarwal.co.in for creation of the account. Right now there is no quota on the size of the space.
