Openvas 7: adding credentials failed

May 14, 2015 less than 1 minute read

I’m creating a new openvas 7 system running centos 7 as a KVM instance.

The installation went fine but it was impossible to create new credentials.

I had a similar issue with my openvas 6 installation, this was resolved by creating the /etc/openvas/gnupg directory and creating the key openvasmd --create-credentials-encryption-key

But on my openvas 7 installation a creation of the encryption key was slooooow. As always Good Randomness is important for creating keys. So I decided to install haveged to get more randomness and hopefully this would speed up key creation.

[root@localhost ~]# yum install haveged

Nothing to do
[root@localhost ~]# 
[root@localhost ~]# systemct list-unit-files --type=service | grep haveged
-bash: systemct: command not found
[root@localhost ~]# systemctl list-unit-files --type=service | grep haveged
haveged.service                             disabled
[root@localhost ~]# systemctl enable haveged
ln -s '/usr/lib/systemd/system/haveged.service' '/etc/systemd/system/multi-user.target.wants/haveged.service'
[root@localhost ~]# systemctl start haveged
[root@localhost ~]# 

The key creation took a only sec.

[root@localhost ~]# openvasmd --create-credentials-encryption-key
Key creation succeeded.
[root@localhost ~]# 

Adding new credentials works like a charm now.

Happy hacking!

Run google chrome inside a fedora docker container over ssh

Update (Mon Jun 8 2015): Running google-chrome inside a docker container isn't stable for me. I switched back to LXC to run google-chrome which seems to be more stable.

Created a docker image to start a docker container with chrome. Destroying the container each time that you start a browser is a easy way to get rid of your cookies and browser history.

lxc templates in Fedora 20

I’m a big fan of containers and used them a lot on Solaris and jails on Freebsd. Containers/jails are the fastest way to spinup an new system and the easiest way to isolate services.

As always with virtualization you’ve to careful with sharing systems or containers that doesn’t below to the same customer or service on the same physical machine since you’re never sure which traces are left behind in the memory etc.

Linux containers are getting more popular since the release of docker

When I tried to create a few containers on Fedora 20, the first attempt (a debian container) wasn’t an success.

On a newly create debian container networking didn’t work.
