In Linux, how do I send packets of a certain size to an IP?

Question

What commands can you run? (must be via the terminal)

Solution 1

You can specify the packet size in ping using "-s" flag:

-s packetsize
          Specifies the number of data bytes to be sent.  The default is 56, which  translates  into
          64 ICMP data bytes when combined with the 8 bytes of ICMP header data.

Solution 2

ping -s nnnn a.b.c.d

sends packets of size nnnn+8 bytes (including header data) to address a.b.c.d, according to the manpage.

-1, the -s argument takes packet size as an integer, not a file name.
