951.0. "OSF/1 V2.1 based system (MLS+ really) with PCM V1.5 looses window connected to console on boot of client. 9608" by 42326::COFFEYJ (The Uk CSC Unix Girlie.) Tue Aug 29 1995 13:30


Well - here you go - here's the details of my "it's very like OSF V2.1 really"
call ...... 

Customer has MLS+ box monitoring another MLS+ box - for the sake of 
arguament they could be considered to be just tailored OSF boxes 
(well for this note anyway) 

He uses PCM to connect to the client over telnet. 
This window is lost however on reboot, or if he's at the chevrons 
prompt when typing boot. 
It is only lost briefly, it dissappears just after loading /vmunix
and then reappears picking up the connection to the 2100 client once 
it's up and running again - obviously this misses one of the most 
crucial states a machine can be in - if it hangs on boot then they 
can do nothing about it. 

I've checked 1.5a notes and though I can't actually see anything 
specific I'll be sending it anyway... 

1)	is this a known issue?
2)	if so which version is it fixed in?
3) 	is it maybe instead a configuration issue?

Obviously if this is unique to MLS+ or is fixed in 1.6+ECO then 
we (CSC, Customer, Engineers) have some negotiating to do ... 
hopefully we can come up with something before then ... 

Oh, the only other bit... I'll check what terminal servers there into out
there on site cause it's just dawned on me this might (or might not)( be
related to that telnet getstatus stuff... ) 



Cheers for any suggestions at all ;-)

    Sounds like the remote system is sending out some sort of a control
    signal (break?) when the system is booting which the terminal server is 
    interpreting as a disconnect. The terminal server then drops the 
    connection which PCM detects. PCM then reestablishes the connection. 
    The best guess is to look into the terminal server settings.
    I remember hearing of some Sun systems doing this, but none of ours.
    When you look into the terminal server, make sure it's software is 
    up to rev.
    
    You should also consider upgrading to PCM version 1.6.

	Well, I had a chat with our local MLS+ guy and he reckons that MLS+
	at that point, which just starting to boot really is no different to 
	OSF/1 so we're keeping this as a possible idea but will check out the
	terminal server side of things first - if we don't clear it there I 
	think it's switch a dumb terminal to "display controls" and plug it 
	into the back of the box and see what's sent. 

>    The best guess is to look into the terminal server settings.
   
	Do we have any good examples anywhere of what the setup on a terminal 
	server should look like?

	Well, it's a DECserver700 and it apparently says Version 1.5 for 
	ds900tm and ROM version - issue 4.0 so I'll try to find someone who 
	can tell me if this is up to date or not (unless someone in here 
	knows).

>    You should also consider upgrading to PCM version 1.6.

	I thought PCM V1.6 wouldn't run on OSF/1 V2.1?
	If I had that wrong please do let me know as I'm sure being on 1.6 
	will make life easier.  Either way I've passed on that although 
	we don't think it will necessarily fix this issue he really should 
	upgrade to V1.5a at least ASAP. 

Cheers

Apparently those two terminal server versions are both the
latest so that's that bit eliminated I guess... now all I 
need is an example of what the different settings should 
be to send to him to compare against his setup.

Does anyone have an example setting for a decserver(700) that works 
for PCM to monitor a console over? 

951.5WILL PCM 1.6 INSTALL ON OSF 2.1??????????42326::COFFEYJThe Uk CSC Unix Girlie.Wed Sep 06 1995 08:0317
951.1>   You should also consider upgrading to PCM version 1.6.

Can you confirm if this really is feasible for a machine based on 
OSF/1 V2.1 - we're more than willing to but I was under the impression 
it would barf on anything less than a V3.0 based system. 

Also are there example decserver settings anywhere I can refer to? 
A ds700 would be nice but any similar one (ds900) will do just to 
give me something to compare it to! 

In the mean time I'll see if I can persuade him to send me his 
settings instead .... not that I've anything to compare them to :-) 
but I'm sure I can do some basic checks.

    As far as setting go there is very little you need to change from the
    default. The following is a snapshot from a DS90TL:
    
    Port  2: (Remote)                      Server: LLANO
    
    Character Size:            8           Input Speed:               9600
    Flow Control:            XON           Output Speed:              9600
    Parity:                 None           Signal Control:        Disabled
    Stop Bits:           Dynamic
    
    Access:               Remote           Local Switch:              None
    Backwards Switch:       None           Name:                     PCM02
    Break:                Remote           Session Limit:                4
    Forwards Switch:        None           Type:                      Ansi
    Default Protocol:     Telnet           Default Menu:              None
    
    Preferred Service: None
    
    Authorized Groups:  63
    (Current)  Groups:  63
    
    Enabled Characteristics:
    Input Flow Control,  Loss Notification,  Message Codes,
    Output Flow Control,  Verification
    
    
    The only other thing that was changed ont his port was that it was
    enabled for listener 2002:
    
    
    Local> sho telnet list 2002
    
    Listener TCP-port:  2002
    Identification:
    Ports:              2
    Connections:        Enabled

Thanks lots..... 

Hopefully this'll settle it ...

....if not I guess I'll end up in political arguaments 
about whether we can get 1.6 rebuilt on a 2.1 system so we 
can use it on MLS+ (if we're lucky).

I assume it's possible to do but will just need paying for...

    Probably. A build system will have to be put together too so it'll be
    expensive!
