The new VMST daemon logically represents several VMS’ combined in a single
process. All these “internal” VMS’ are considered interconnected. For example:
vmst -v1 -v2 -V flame:3:3 …
is equivalent to two local VMS’ numbered 1 and 2 connected to each other, with each
also being connected to VMS number 3 on host flame.
Arguments
vmst [options] -v <mps_num>
-b <port> The base TCP/IP port on which to listen for application requests
(default is none).
-h <hostname> This parameter specifies the host name of an alternative network
interface (1e0, le1, etc.).
-P <secs> Specifies the ping timeout for monitoring remote connections
(default is none). If a daemon process (e.g., SBRM) running on a
remote machine generates consistent traffic, then the lack of said
traffic for some time is interpreted as a sign that this daemon is
down.
If this option is specified, and there is no message traffic from the
daemon for a time longer than specified here, VMST disconnects
the remotely connected daemon if the process is identified with
the keyword PING in the services file. (See The
/etc/services File on page 129.)
-p <max_num> Maximum line/service port number (default is 508). VMST now
allows use of MPS numbers equal to or larger than 255. All
existing software works with numbers less than 255, as is (by
default, VMST continues to allow phone lines/service port
numbers less than 255 only). This option is not needed for large
MPS numbers alone (for example, vmst -v 555): however,
even with the -p option, the phone line numbers equal to or larger
than 255 can not be used with real MPS’ because of software
limitations: they should be used with simulated MPS’ only (see the
-v s option below).
-r <file> Redirects debugging output to the specified file.
-s <port> Specifies the services port number to be used by VMST when it
starts. (The default is the next available port taken from the range
as defined in the services file.) Each service port number must
be a valid service port for the VMST process as defined in the
services file on each host (see The /etc/services File on
page 129). This provides a specific port address that can be used
by other VMSTs for the purpose of direct connection. This number
should be specified in the range 1-10. If it is necessary to go
beyond this limit, the services file must be modified accordingly.
