256.0. "LOCAL decserver flop/ssu problems" by QUAKKS::DWORSACK () Wed May 14 1997 16:40

I've been a LONG time user of flop/ssu.

i use watn to connect my vaxstation 2k running vms 5.5
with decwindows xui.
(btw,, the only thing i dont like about decwindows, is the mouse button
3 for paste, and when i'm at work mb2 on motif :-( if someone has 
worked around this, i'd be happy to hear also)..

once logged into watn i connect to netway, and then to my workstation on
my desk at work, and run ssu to open my multiple windows.


like i said that works fine, but now i have tried to connect to a 
decserver at a digital facilty local to my home, and cant seem to get the
flop/ssu to connect properly. i'm quite sure its somthing to do with
the decserver port characteristics, and tried many things, without success.
so i thought i'd drop this note and see if someone else can give me advise
or check their port characteristics next time you log in.

the symtom is, when i execute my ssu on my server node,
"$SSU.EXE -NOLOGOUT -LOGINOTHERS -NODISABLE"

i get a couple characters on the screen, then the window goes away, and
flop exits on my home machine...

   >ssu
   >AAJ!AAJ!AAJ  then right here the window goes out.

i'll show the decserver port characteristics, and then the watn port char...

thanks in advance for any help,

Jim

The AAJ stuff shows that SSU is trying to enable multiple sessions, but
the other end isn't recognizing the protocol.  Do you have the protocol
appropriately switched on ?

256.3JAMIN::OSMANEric Osman, dtn 226-7122Fri May 23 1997 16:0314
I'm talking about the TDSMP (Terminal Device Session Management Protocol) which
is the basic protocol that SSU uses for switching between sessions.

The sequence <ESC>!AAJ or something like that would be the initial directive
to enable multiple sessions.

So make sure "multiple sessions" are enabled at both ends (the FLOP end
and the SSU end) and that nothing is filtering out escape characters.

Any other readers here that use FLOP that can lend this person a hand ?
I was an SSU developer but I don't run FLOP !

/Eric
256.4Use SSU instead of serverGIDDAY::GILLINGSa crucible of informative mistakesSun May 25 1997 20:4571
    I use FLOP (in fact, I'm running on it right now). I don't use the
    terminal server as the other end, I prefer to use an OpenVMS system.
    The main advantage is that you can enable virtual terminals under
    OpenVMS and thereby reconnect to your sessions after losing the
    phone line. You can also be sure you're running the right protocol.
    
    By chance, I still have the transcript of my initial connection in
    a scrollback, so here it is:

    The blank line is the terminal switching from being the LAT session
    into the first SSU session. By symbol "ssu" is defined as:

  SSU == "$SSU -loginothers -nologout -nodisable"

   nearly 4 days. That allows me to have all my FLOP sessions "hibernate"
   over the weekend and reconnect by connecting back to the disconnected
   LAT session.
   
   For most terminal servers I think the command to activate TDSMP is 
   ENABLE MULTI, but since I never use it I can't be sure.

256.5getting closer ?/QUAKKS::DWORSACKTue May 27 1997 10:1310
    >So make sure "multiple sessions" are enabled at both ends 
    i tried that option on the terminal server, but all i got when
    i opened another session/window was another window to the decserver
    prompt... i usually get the window straight to my workstation.
    
    
    JOHN, SHOW ME A SHOW PORT FROM YOUR DECSERVER.
    
    thanks guys,,, johns show port should help me..

    If you enable sessions to the terminal server (as opposed to a host
    with the SSU utility), then opening another session WILL give you 
    another terminal server prompt...
    
    Oh wait a minute... with the later versions of FLOP, I got Jeff to
    add support for service names; are you specifying this when you
    start FLOP? Perhaps your terminal server doesn't support this.
    
    I agree with .-?; use SSU on your host rather than in the server.

    >    I agree with .-?; use SSU on your host rather than in the server.
    this IS what i do...
    
    ok, i'll restate the problem.
    
    i call a bank of modems, which are connected to a terminal server
    (very simular to watn)... then i connect to netway (again same as
    watn). then i telnet to my workstation in my cube, and login, and
    do ssu == "$SSU.EXE -NOLOGOUT -LOGINOTHERS -NODISABLE"
    
    then if i go to my flop window and select
    "Create new DECterm session" i have another window directly to my
    workstation (not the terminal sever).
    
    i think my problem is stated a couple back,
    >So make sure "multiple sessions" are enabled at both ends (the FLOP
    >end
    >and the SSU end) and that nothing is filtering out escape characters.
     but i cant seem to figure what characteristic i'm missing to keep
    it from filtering out the esc sequence... :-(
    
    John Gillings did give me a show port, but i cant seem to figure 
    how to change my protocol on the port...
    ive also tried passall and pasthru as session characteristics, but no
    help. 
    
    puzzled ???

The above won't start ssu, it merely defines the symbol !  You then need
to use the symbol.

As for your question about how to enable the protocol, the only two ways
I know are for ssu and for dec terminal servers.  ssu normal enables
the protocol if you use the symbol you defined up above, or merely start
ssu with

	$ mcr ssu

On terminal servers, you say

	set port multi enable

>The above won't start ssu, it merely defines the symbol ! 
eric, i really thank you for your time in here, but i was just
showing the symbol so you ddidnt have to ask me what qualifiers i use
in you next note !!

but as i said, i really dont want multi sessions from the lat box !!
i want the terminal server to pipe the mulitsessions THRU its box, so 
i have multi sessions between my server on my OFFice box and the
vaxstation running flip at home...

again, i've tried all kinds of passthru and passall commands on the decserver
but i still get those characters when i run ssu on the server at my office.
when i do multi enable(like eric mentioned before) i do not get the garbage
characters, and then i get multi sessions from the lat box.... SOMTHING is
not alowing those to pass back to my vaxstation at home ... sigh...

    You mentioned telnet in the final hop.
    Make sure the telnet setup is fully transparent.
    (Don't ask me what to check, I don't know.)
    
    BTW, you don't indicate where the your node vs the dial-in are, but
    given a major chuck of the US is all on one extended LAN, it might
    be possible for you to enable the right group codes on your system
    to allow it to be seen by the terminal server you are dialing into,
    thus removing the need for all the extra connects/telnets/etc. 
    
    The terminal server output you posted in .0 doesn't show the group 
    codes enabled for that server; you'll need them to try this out.
    
    The output in .0 also would seem to indicate (though you'll need to
    look at SHOW SERVER output to confirm) that it already has TCP/IP
    enabled on it. If so, you should be able to telnet directly from the 
    dial-in terminal server to your node without the intervening hops.
