Cisco FirePOWER SFR Module Cannot Ping
KB ID 0001174 Problem On a newly deployed FirePOWER service module I wanted to test connectivity and attempted to ping a public IP address. This is what happened; > expert admin@Petes-SFR:~$ ping 8.8.8.8 ping: icmp open socket: Operation not permitted My first though was, “Well you have to set a default gateway on the SFR when you set it up, so the firewall is probably blocking ICMP”.

Mac OSX – GNS3 Connecting To the Internet
KB ID 0001170 Problem I have a love hate relationship with GNS3, I appreciate it’s brilliant, (when it works). I also appreciate that it’s free, and people put a lot of effort into its development for very little reward. But when I try to do simple things, like connect my projects/labs to the internet and it’s massively overcomplicated I get pretty exasperated. With Windows this is easy, (I’ve probably blogged...
