Signaling traffic is protected by TLS using strong encryption suites. Signaling connections are outbound only and use URLs for session establishment to Webex services. The Webex app and Webex devices use HTTPS and WSS (secure websockets) for signaling. The Webex app and Webex Room devices establish signaling and media connections to the Webex cloud. All data is encrypted in transit and at rest. Webex messaging micro-services, messaging storage services and media servers). Webex data centers for identity services, meeting services, and media servers) or hosted in a Cisco Virtual Private Cloud (VPC) on the Amazon AWS platform (e.g. Webex services for meetings and messaging are primarily hosted in globally distributed data centers, that are either Cisco owned (e.g. Cisco’s Webex Cloud never initiates outbound connections to cloud registered Webex apps and Webex Room devices, but can make outbound calls to SIP devices. For on-premises SIP-based call control products such as Cisco Unified CM, a SIP session is established through a border controller such as Expressway C & E, or CUBE SBC for calls to and from the Webex Cloud.įor details on the specific network requirements for the Webex Calling service see: Īll cloud registered Webex apps and Webex Room devices initiate outbound connections only.

Webex Room devices, Cisco IP Phones, and 3rd party products can join Webex Meetings using SIP. The Webex Calling service and on-premises call control products such as Cisco Unified CM use SIP as their call control protocol. Webex cloud and on-premises call control registered devices using SIP The Webex app can also use the SIP protocol to join Webex meetings, but this is subject to the user either being called via their SIP address or choosing to dial a SIP URL to join a meeting (rather than use the functionality of the meeting native to the Webex app). The Webex App uses HTTPS signaling for Webex messaging and meeting services.This feature allows Webex devices to be administered via Webex Control Hub and to participate in Webex Meetings using HTTPS signaling (for details see ). On-premises SIP registered Webex devices can also use HTTPS signaling if the Webex Edge for devices feature is enabled.Cloud registered Webex Room devices use HTTPS signaling for all Webex services.And you have figured out what port yum uses in Linux/Amazon AWS.All cloud registered Webex apps and devices use HTTPS to communicate with Webex messaging and meetings services: I hope this has resolved your issues with yum repositories. These were not enabled on the Security Group of the EC2 instance. NOTE: This was only changed on the NACL associated with the public subnet of the EC2 instance. You will need to open the TCP ephemeral ports (1024-65535) for Ingress in order for the response to be allowed to re-enter your instance. One of these rules states opening up the Ephemeral Ports. After further reading on the documentation, I found the VPC recommended NACL rules. So lets enable ports 20-21 & 80 in the Public NACL right? 80 for the main comms and repos and 20-21 if repo happens to be from an FTP source. : Timeout on : (28, ‘Connection timed out after 5000 milliseconds’)Īfter a quick Google around, it appears yum uses ports 20, 21 & 80 (& 443 if using RedHat). Loaded plugins: extras_suggestions, langpacks, priorities, update-motdġ2: Timeout on : (28, ‘Connection timed out after 5000 milliseconds’)

These were the errors I was ~]$ sudo yum update -y

#Ephemeral ports aws install#

The mirror list kept timing out with error: Trying other mirror.I needed to find out which port(s) yum uses in Amazon AWS/Linux to allow the updating and install of repositories (repos) and allow these through the NACL. I’ve found and issue with updating yum repos from a new Amazon Linux EC2 instance. I haven’t posted in a while because I stopped learning new things.
