 Hello Network,
	The athena cluster in e52-364 is having a network
	problem. 2 weeks ago the entire cluster was down.
	I replaced the transcever (very hot & col light constant)
	and the cluster came up. 2 days latter it was reported that
	the cluster still is having problems. I replaced the 
	transcever from one of Rons stock. 

	The cluster mgr (John Dippold) left me v-mail last week
	that the cluster is still having problems.

	Symptoms are:
	      -	Sun workstations recieve intermittent "network
		failure" error message. 
	
	      - Able to telnet in and out of cluster but telnet
                within the cluster gives "telnet: setsockopt 
	       (IP_TOS) (ignored): Not owner". Then times out.

              - Jack # e52-364

              - Able to log into all workstations.

	SWap the DELNI??? I don't know who owns it....
	I will forward to telecoms upon request...

 John
