                        NETWORK CHECKOUT

      As of August 21 we had performed the following ver-
ifications with the sites listed below.  These verifications
were done on an arranged basis and do not indicate any degree
of continuous availability.

        In the category "NCP-107" the heading is somewhat mis-
leading.  It does not indicate a thorough checkout of all the
NCP functions described in Document 1 and RFC-107.  It only
indicates that the NCP in question functioned to the extent
required to respond to a RESET (a necessary condition for the
Rand NCP to consider the remote host "up") and that the NCP
performed the functions necessary for an ICP.  Thus, this col-
umn really indicates only a small degree of NCP completeness.
Such function as ECHO, Give Back, error message generation
and so on were not checked.  We have checked some of these
functions with UCSB and SDC but not exhaustively.  This is
mainly due to the tedium of such a process.  BBN is currently
writing a protocol certifier for their DDP-516 host that will
do this automatically.

na-- the function is not applicable to the host due to its
     operating system or intended network use

?--- a comment follows for that function in that host

COMMENTS:

SRI NIC -- both a sever telnet and logger exist;  however, they
           do not process the telnet messages correctly.

MIT Multics -- we were only able to connect to an interim
          logger that sent a 'ts' message.

SDC  -- the logger causes the system to crash following login

     Any discrepancies should be noted via phone call.  This
RFC will be updated in about one month.
