-/*----- Revision history --------------------------------------------------*
- *
- * $Log: peer.c,v $
- * Revision 1.6 2001/06/19 22:07:59 mdw
- * Use magic number for packet size.
- *
- * Revision 1.5 2001/03/03 11:15:19 mdw
- * Set the socket send and receive buffers to maximum. At least this way,
- * we won't drop large packets on the floor. If the administrator wants to
- * prevent fragmentation of TrIPE messages, he can lower the MTU on the
- * tunnel interface. Getting path-MTU stuff out of the kernel is too much
- * system-specific hard work for this program.
- *
- * Revision 1.4 2001/02/16 21:40:24 mdw
- * Change key exchange message interface. Maintain statistics.
- *
- * Revision 1.3 2001/02/04 17:10:58 mdw
- * Make file descriptors be nonblocking and close-on-exec.
- *
- * Revision 1.2 2001/02/03 22:40:29 mdw
- * Put timer information into the entropy pool when packets are received
- * and on similar events. Reseed the generator on the interval timer.
- *
- * Revision 1.1 2001/02/03 20:26:37 mdw
- * Initial checkin.
