What does Telemachus send to the swineherd to do?

Telemachus tells the swineherd to "go quickly and tell faithful Penelope that I am safely back from Pylos. I will wait here till you have told her your news, in private, and returned. No one else must hear it, since many of them are hostile to me." Telemachus wants Eumaeus (the swineherd) to keep things on the down-low because he knows that he has enemies at the palace.
