NIS and No buffer space available

[Graham Williams <Graham.Williams@cmis.csiro.au>]

I'm trying to set up NIS on a "unstable" Debian machine. I believe
I've set up the config files appropriately.

$ apt-get install nis
...
Starting NIS services: ypserv yppasswdd ypxfrd ypbind

But it then sits there waiting?

I exit from this and try 

$ ypbind -d
...
Cannot register service: RPC: Unable to send; errno = No buffer space available

Any ideas what might be going on or where to start investigating?
(I've had the "No buffer space available" problem in other places
also?)

Regards,
Graham
