Pilots - help ! problems with dog,shadow on 3130

[Dhekne c/o NCST]

Hey, there !
	We have iris-3130s connected by ethernet. Telnet, ftp
are working properly, without any problem. 
	I am able to run dog,shadow and flight on a single system 
with -i and -o option.
	But I am unable to run 'dog' and 'shadow' over the network.
As soon as I run them, they come out with the error message
'Ethernet Initialisation failed'. 

	Are there any settings for the ethernet that I have missed ?

	Thanks !!
