3915.0. "INTERNET COMM ERROR WITH SNMP DEVICES ???" by MFRNW1::DENIS () Mon Oct 19 1992 13:58

    One of our customers is getting the error message:
    "INTERNET COMMUNICATIONS DEVICE ERROR" when he performs
    any show operation on a registered SNMP device. I always
    understood that this was a VMS status message. However
    the customer says it is occurring with HP-Apollo stations
    and Synoptics devices.
    The versions in use are:
                ULTRIX V4.2a on a DECstation 5000/240
                DECMCC BMS V1.2
    I would appreciate any tips ,suggestions pointers hints etc...
    cheers,
    Denis

	Internet Device Communications Device Error is returned by the 
	SNMP AM when one of the following operations fails with a fatal error.


		o gethostbyname
		o creating a socket
		o send to
		o select using readmask
		o receive from 
	
	Check if the Ultrix commands ping and nslookup works correctly.
	If it does, then let me know, and I'll ask you to try out some other
	stuff.

3915.3Try re-enrolling the AM.YAHEY::BOSEThu Nov 05 1992 15:297
	Can you try re-enrolling the SNMP AM. (You might want to do an mcc_kill
	first, although it is not necessary). For some inexplicable reason,
	this sometimes get rid of the Internet Device Communication error. 
	Try this out and let me know what happens.

3915.4re-enrolling stops it for a while !!MFRNW1::DENISMon Nov 30 1992 02:077
    Yes,  re-enrolling the SNMP AM does actually get rid
    of the error , but can shed any light on the message
    itself ? does it make any sense to you ?
    cheers

	Denis,
	
		The SNMP AM returns Internet Device Communications error
	when one of the socket routine calls fail with a fatal error (ie
	one of the routines gethostby*, socket,select,or recv* fails).
		
		We have noticed that killing the SNMP AM process and
	restarting it sometimes gets rid of the problem. (Note that
	re-enrolling the SNMP AM does exactly that). We haven't had
	time to investigate this behaviour further.

	Rahul.

3915.8Thanks for the help!!SNOTTY::BARRYPloppy Sir, Son of PloppyTue Sep 26 1995 12:396
Cheers Conrad.......after I have done this do I then have to stop and start
DECMCC, reboot the machine or should the alarm errors stop straight away ??

Regards

    I've not encountered the alarm errors myself. But whenever I've
    re-enrolled an access module, there's been no need to restart  the
    machine. Just restart the polling/alarming process.
