Error updating locale cisco phone
If a host is reinstalled and has a different key in ‘known_hosts’, this will result in an error message until corrected.
If a host is not initially in ‘known_hosts’ this will result in prompting for confirmation of the key, which results in an interactive experience if using Ansible, from say, cron. If you understand the implications and wish to disable this behavior, you can do so by editing Also note that host key checking in paramiko mode is reasonably slow, therefore switching to ‘ssh’ is also recommended when using this feature.
Ansible is not just about running commands, it also has powerful configuration management and deployment features.
There’s more to explore, but you already have a fully working infrastructure!
Tower provides a very robust database logging feature where it is possible to drill down and see history based on hosts, projects, and particular inventories over time – explorable both graphically and through a REST API.Only problem is since there is no application running, there is no place to specify the address!Thank goodness for DHCP option 150 which does this for us when the phone grabs an IP address after loading the bootloader.“Go With the Flow” is a crash-course e Book designed to help you learn all about flow data, it’s uses, and how to troubleshoot network traffic issues. Getting Cisco phones working with asterisk may seem like a daunting procedure; getting SIP firmware installed on the phone, loading up the the firmware files in the tftp server, fearing that you will somehow brick the phone by an incomplete firmware upload…But I am here to reassure you that once you understand how Cisco phones update themselves, the fear and trepidation will subside. They just need a tftp server to update its firmware and it doesnt even have to be located on the asterisk/phone system itself. But what is essential in upgrading these phones is a DHCP server with option 150 enabled – an option to auto-provision the tftp server ip address when the DHCP server hands out the regular ip address to the phone.
