88.0. "Problems with cisco terminal servers" by EEMELI::OJUSSILA (Olli Jussila, IS/SMGT Finland) Mon Aug 09 1993 19:56

    
    
    	We have set up CM connection to over cisco terminal server.
    	Connection is provided by Finnish PTT by their DATANET service.
    	This is TELNET connection
    
    	For some reason connection is lost every 10 minutes 
    	"Console link for system HOVIK lost - Bad file numer"
    	But it is restored right away. But if i have connect
    	to system HOVIK I have escape and reconnect to be able
    	to type again. We have also test connection over DATANET
    	(by different cisco terminal server) and this connection is lost
    	to that system usually at the same time. We have
    	also console telnet connection over DATANET to DS300 
    	This connection works fine.
    
    	Inactivity timers has been disabled on cisco terminals servers.
    	
    	Do you have any ideas why we loose connection to cisco terminal
    	servers?

Olli,

  Strange, however, we have never done any testing with cisco
  terminal servers.

  Every 600 seconds, your 10 minute period, we send a TELNET
  getstatus and wait for a response, does the cisco terminal
  server resond to a getstatus TELNET command, if so, what is
  its response.  

  I am afraid that until we can get hold of a cisco terminal
  server to test, this is not a supportable server.

Cheers,
Phil

    How I can do this? Now I have disabled node in CM and have
    done Telnet connection to the node and waiting...

Olli,

  You need to send the escape character (usually ^]) then type
  at the telnet> prompt "send getstatus" let me know what the
  terminal server returns, you may have to do a "set options"
  first.

  For example, on our DECserver 300, we perform the following
  sequence...

  # telnet server 2016
  Trying .......
  Connected to qhlive.reo.dec.com.
  Escape character is '^]'.
  ^]                                            <- I typed this
  telnet> set options                           <- I typed this
  Will show option processing.
  ^]                                            <- I typed this
  telnet> send getstatus                        <- I typed this
  Sent suboption STATUS SEND
  RCVD IAC SB
  Received suboption STATUS IS
  WILL SUPPRESS GO AHEAD
  DO SUPPRESS GO AHEAD
  WILL STATUS

  The results of doing this to a VMS system running TCPIP Services
  for VMS for example is the following :

  # telnet hostname
  Trying 16....
  Connected to hostname.reo.dec.com.
  Escape character is '^]'.
  ^]
  telnet> set options
  Will show option processing.
  ^]
  telnet> send getstatus
  Remote side does not support STATUS option
88.4Cisco: Remote side does not support STATUS optionEEMELI::OJUSSILAOlli Jussila, IS/SMGT FinlandWed Aug 11 1993 17:3425
    
    Cisco dosen't support STATUS option.
    
  telnet> set options
  Will show option processing.
  ^]
  telnet> send getstatus
  Remote side does not support STATUS option
 
    We try to get more information if STATUS option can be enable on
    these servers. PTT will contact to Cisco.
         
    It is possible to disable this check in CM. Line seems to ok
    anyway. CM reports 
    ... 18:16:53 Critical CMgr Console link lost...
    ... 18:16:53 Clear    CMgr Console OK...
    
    Note that time stamp is same for both events.

Olli,

  We cant disable this for you I'm afraid, we also dont have the time right
  now to invest in the effort to make this happen for the next release, we
  are madly trying to get everything working on all 4 platforms so we can
  get a field test kit out.

  Let me know what your PTT says. This may be a sales opportunity with the
  PTT to sell some DECserver 90M's which have this capability and because of
  their Flash memory do not need to be downloaded when on a remote site!

Cheers,
Phil
