Python – get system hostname

 
By using socket.gethostname() we can get hostname of system:
>>> import socket
>>> socket.gethostname()
'localhost'
There is one more way to get hostname is by using platform.node():

Ubuntu – apt-get auto complete not working

To fix apt-get auto complete issue we need to edit /etc/bash.bashrc file.
Open /etc/bash.bashrc file with any text editor, here I am using vim.
$ vim /etc/bash.bashrc
Now search for below lines in /etc/bash.bashrc file:

Get pid, user and command for the particular port in illumos

While the Solaris has the updated netstat with -u flag, illumos requires certain improvements in sockinfo, and possibly, rpcbind (tcpConnCreationProcess shows the old PID for rpcbind, until it did not become a demon). With help of pfiles is possible to obtain the desired information about pid for particular port, so I wrote a small pfiles-based utility which allows to determine the PID, user and command for the particular port:
# ./ptcpstat

what's next with rsyslog?

Now that we have released version 8.7.0, planning for 8.8.0 is in full force. I thought I'd share some of those things that made it to the top of the todo list:

Less is More in the New Xen Project 4.5 Release

If we used code-names, the Xen 4.5 release should be called Panda on Diet! We have 78K new code with 141K deleted. In effect this release has -63KLOC code than the previous one.

The net effect of a skinnier Xen Project Hypervisor code base is increased usability, simplicity and innovation. This is all by design and one of many steps we’ll continue to take to fine-tune our development and release cycle.

Install Windows 7 with VirtIO Drivers on RHEV 3.4

One of the best ways to improve the performance of Microsoft Windows guest is to use paravirtualised devices and drivers for KVM in the guests. This provides close to bare performance (up to 95%). These drivers are provided by the virtio-win RPM packages in the RHEL.
1. The virtio-win packages can be found on RHEL server /usr/share/virtio-win/

Cannot set user id: Resource temporarily unavailable while trying to login or su as a local user in CentOS

If you encounter this error while trying to login or su –login
# su --login user1
"cannot set user id: Resource temporarily unavailable" while trying to login or su as a local user in CentOS.
To resolve the issue,  extend the nproc value in /etc/security/limits.conf for the user.

We are looking to hire someone who loves working with open source developer communities.

We are looking to hire someone who loves working with open source developer communities.

The ideal candidate would have experience with the Oracle Database and at least two or more open source developer environments. The successful candidate would join a team of people responsible for helping database app developers be more productive while using prominent open source development tools. That person would also help to represent the needs of the community back to Oracle development.

rsyslog branches and git history

There was a lengthy mailing list discussion in November and December  of 2014 of whether or not to avoid git merge entries. There was also an intermingled discussion on QA and CI. The idea was to trim the git history and make sure tests are run a quickly as possible. As a result of that discussion, I added more automated testbench runs, which also required a new branch master-candidate, which is used as a staging area to run the test, and from which changes are (manually) migrated to master when all testbench runs are OK.
