I want my Interactive (IX 2.2) UNIX files backed up onto the DAT tape unit attached to our SUN server. I can export my NFS filesystems to the SUN server but "root" on the SUN cannot read all the files(e.g. /etc/shadow). This is because the Interactive Version of NFS assigns uid (-2 ?)"other" to all accesses to the IX NFS filesys. The SUN allows my IX machine to have full access (even as root) to selected exported filesystems with the following syntax in the /etc/exports file: /home -anon=0,access=ixhost Interactive NFS uses the following syntax in the /etc/exports file. / sunhost We are using Interactive UNIX 2.2 with NFS 2.1. Does NFS 2.1 support remote root access to an NFS filesystem? TFM says "No SU Over the Network", but we had a similar problem with HP NFS and it was solved by patching the Kernel to change the NFS User ID from -2 to 0. Anybody know where to patch the IX kernel? I tried the syntax used by the SUN between two IX systems, it did not complain, but it did not work either. The `showmount` command does not complain either. If I have several IX machines, does this mean I can't do a remote backup from one tape drive? Do I have to buy tape drives for ALL my IX nodes?! I suppose I can back up the 90% of my files which are readable by "other" on the DAT and do a separate backup to floppy of the rest, but what a pain! -- James R.
