CloudFlare Supports the Passage of the USA Freedom Act
Earlier today, the lower house in the U.S. Congress (the House of Representatives) passed the USA FREEDOM Act. The Act, if passed by the Senate and signed by the President, would seek to sunset the National Security Agency’s bulk collection and mass surveillance programs, which may or may not be authorized by Section 215 of the PATRIOT Act. Under this authority the U.S. government has established its broad surveillance programs to indiscriminately collect information. Other governments have followed this lead to create additional surveillance capabilities—most recently, the French Parliament has moved a bill that would allow broad surveillance powers with little judicial oversight.
Restricting routine bulk collection is important: it’s not the government’s job to collect everything that passes over the Internet. The new version of the USA FREEDOM Act keeps useful authorities but ends bulk collection of private data under the PATRIOT Act. It also increases the transparency of the secret FISA court, which reviews surveillance programs—a key start to understanding and fixing broken policies around surveillance. The Act would also allow companies to be more transparent in their reporting related to FISA orders.
To be clear, we continue to be supportive of law enforcement and work Continue reading

Public Key Authentication on Cisco IOS
Have you ever been in that situation that you needed to apply the same configuration quickly on multiple Cisco routers? If yes, youPublic Key Authentication on Cisco IOS
Have you ever been in that situation that you needed to apply the same configuration quickly on multiple Cisco routers? If yes, you probably wrote a script that connected to routers and sent appropriate IOS commands. One problem that you certainly had to solved was forcing your script to enter login credentials such as username and password. Moreover if you secure an access to privileged user mode of routers with an enable secret command you had to tell the script how to enter that password as well.
All the issues I have mentioned above can be easily solved with Expect scripting language. Expect sends commands via telnet or ssh session as the human would. However encapsulating IOS commands to syntax recognized by Expect language every time you need to change routers' configuration seems to be not very comfortable. That is why public key authentication for Cisco routers can be handy.
Public key authentication allows you to log in to your routers using RSA key instead of a password. But firstly key-pair - public and private key must be generated and a public key copied into a config file of the router. Then you can connect to the router with your private key. A private key is the key that should Continue reading
