Cisco goes to space

Cisco Systems wants to put a router on every communications satellite. The networking giant has already sent the first one into space. The company announced that the router has successfully completed initial in-orbit tests, after being launched Nov. 23 aboard the Intelsat 14 communications satellite into geosynchronous orbit, 22,300 miles above the Earth. The move is one small step in a bold, new Cisco initiative dubbed Internet Routing in Space (IRIS), which company executives say extends the same Internet protocol-based (IP) technology used to build the World Wide Web into the heavens. The long-term goal, they say, is to route […]

How to use archive command to save configuration

In a large/critical network, it is fundamental backup the Cisco configuration for two reasons: Rollback configuration Restore configuration in case of a broken router There are two ways to backup: manually (using write command each time that you would save running configuration) or automatically (using software like Ciscoworks, HP OpenView, … ). In this tutorial, I would explain a different method to backup configuration: the archive command. Introduced into Cisco IOS Release 12.3(4)T, the archive command permits to save a copy of the current running configuration to different path: ftp, http, https, rcp, scp, tftp servers. Moreover the archive command has […]

Transport Layer Security Renegotiation Vulnerability

Security researchers Marsh Ray and Steve Dispensa unveiled the TLS (Transport Layer Security) flaw on Wednesday, following the disclosure of separate, but similar, security findings. TLS and its predecessor, SSL (Secure Sockets Layer), are typically used by online retailers and banks to provide security for web transactions. Ray explained in a blog post on Thursday that he had initially discovered the flaw in August, and demonstrated a working exploit to Dispensa at the beginning of September. This vulnerability could impact any Cisco product that uses any version of TLS and SSL.

Slow ADSL with 12.4 IOS version?!

Recently, I have upgraded my Cisco 2650XM from 12.3 to 12.4 version; I use it to connect my PC to Internet, but something goes wrong. After the upgrading, I have tried to downlad an ISO image but the speed was very low (about 300KB/s and not 700KB/s). Mhhh this is strange! I have begun the troubleshooting but no error, no warning message. So I have reset my current configuration, but nothing… no real improvement.
