Many thanks for answering my question. Hopefully my noisy X4200 will be installed in the data centre tomorrow (Thursday); I had a set back today while fighting with the Remote Console feature of ILOM 1.1.1 (i.e., it doesn't work). :-( Just ssh into it and use the serial console from within

OSX *loves* NFS - it's a lot faster than Samba - but you need a bit of extra work. You need a user on the other end with the right uid and gid (assuming you're using NFSv3 - you probably are). Have a look at :
