# ssmpingd(1)

check if you can receive IPv4/IPv6 multicast data from an internet host

Part of [ssmping(1)](/ssmping/1.md).

## NAME

ssmping - check if you can receive IPv4/IPv6 multicast data from an internet host

## SYNOPSIS

**ssmping** \[ **-46v** \] \[ **-I** *interface* \] \[ **-c** *count* \] \[ **-s** *size* \] *host*

**ssmpingd**

## DESCRIPTION

**ssmping** and **ssmpingd** are network level multicast management tools that can be used to check whether one can receive multicast packets via SSM from a host. The host target given to **ssmping** must run the **ssmpingd** daemon, which listens on UDP port **4321** for IPv4 and IPv6 unicast requests. When it receives one, it responds to a well known SSM multicast group which **ssmping** just have joined. Depending on whether the request was made with IPv4 or IPv6, the group is **232.43.211.234** or **ff3e::4321:1234** respectively.

## OPTIONS

For **ssmpingd** there are no options. For **ssmping** the options are as follows.

- **-4**

  Force IPv4

- **-6**

  Force IPv6

- **-v**

  Print client and server version information.

- **-I** *interface*

  Interface to join on

- **-c** *count*

  Stop after sending (and receiving) *count* requests (and replies)

- **-s** *size*

  Request replies to have a size of *size* bytes

## SEE ALSO

## HISTORY

**ssmping** and **ssmpingd** were developed by Stig Venaas during the early days of the m6bone, the IPv6 multicast backbone.
