ICMP (Internet Control Message Protocol) is a network layer protocol used by network devices, like routers and computers, to send error messages and operational information. It’s part of the IP protocol suite.
Common use:
The most familiar use of ICMP is the ping command, which checks if a host (like a virtual machine) is reachable and how long packets take to travel to it.
How to enable PING ICMP packets on your virtual machine?
This functionality can be enabled in two ways:
- In the security group rules of an existing workspace by the workspace owner
- In the catalog item's security group rules
In the workspace
Some catalog items allow the owner of a workspace to change the security groups. In this case, once a workspace is running, a new security group rule can be added using the template “Allow ping”. Please check the following documentation page to add a security group rule to a running workspace.
In the catalog item
If a workspace doesn’t allow the workspace owner to change the security groups, this rule can be enabled in a catalog item at the last step of the catalog item creation. In the field “Additional access rules (open ports)”, click on “+” and choose “Allow ping” template.
In the “Allow ping” template, the following fields are pre-filled and can be modified:
- ICMP as a network protocol
- Both “From port number” and “To port number” are set to 8
- The traffic direction is “in”
- Fill in the desired IP address in the field “IP address.” If you keep the default value of “0.0.0.0/0”, it means that your workspace will allow ping from any IP address.
