Here are some recently updated items in the yum repositories:
Worthy of mention is the update to gnutls, which fixed CVE-2014-0092. That's the so called Linux version of the "goto fail" vulnerability. Other yum packages recently updated include: Name : iproute Summary : Provides Advanced IP routing and network : device configuration tools Description : The iproute package contains networking : utilities (such as ip and rtmon) :which are designed to use the : advanced networking capabilities of recent : versions of the Linux kernel. Name : iptraf-ng Summary : A console-based network monitoring utility Description : IPTraf gathers data like connection : packet and byte counts, interface : statistics and activity indicators, and : TCP/UDP traffic breakdowns.
You can find additional information on these, and many other recently updated packages, by typing yum info recent or
yum list-updateinfo new from the security yum plugin—both are done from the command line.
At the FredLUG meeting on February 22nd, we were treated to a fascinating talk about the inner workings of Bitcoin software, byAlex Akselrod, who writes Bitcoin code. The feature for this FredPod episode is over an hour of highlights from that talk.
We’re also planning for Hardware Freedom Day on March 15th. Several of us will demo our Raspberry Pi and Arduio devices, and chat about the role of patent-free hardware with visitors who stop by.
