+   Set a MD5 password to be used with the tcp socket that is being used
+   to connect to the remote peer.  Please note if you are using this
+   command with a large number of peers on linux you should consider
+   modifying the `net.core.optmem_max` sysctl to a larger value to
+   avoid out of memory errors from the linux kernel.
