Chapter 10. File Access

On the other hand, using Netware mode (if your ﬁleserver runs Netware 6.5 or later) means you don’t

have to assign uid and gid values to all home directories from the Linux side, since Netware will do this

translation on the server side. However, since a NFS export from Netware 6.5 doesn’t support hard links,

the export can’t be used as a home directory without special care. Also, be aware of the fact that trustees

won’t work, so a shared directory where several people have read/write permissions can’t be used in a

decent way.

10.2.4.1. Requirements

10.2.4.1.1. Novell Netware Requirements

First you need to make sure that you have the Novell Native File Access for UNIX installed. This

contains the NFS server components and NDS schema extensions. You should install the available

service packs for your Netware system. Then Native File Access for UNIX is initially installed, it runs

the command schinst, which extends the NDS schemas.

If NDS is reinstalled, if you for example installs a Netware service pack, you may have to run it

manually afterwards. After schinst you should run nisinst which extends the schemas with NIS info,

which is needed. You should run nfsstop before and nfsstart after these commands.

10.2.4.1.2. UNIX Requirements

Of course you need some user handling, for example NIS, LDAP, NDS or similar.

10.2.4.2. NDS Conﬁguration

Before you can export a Netware traditional ﬁle system you need to run the command:

$ add namespace nfs <filesystem>

Before this you won’t see the ﬁle system in the list of ﬁle systems possible to export in ConsoleOne and

the NFS server won’t be able to export it even if you add the ﬁlesystem to SYS:\ETC\NFSEXPRT

manually

When you have added the NFS namespace you need to export some volumes from the Netware server. In

Netware 6.0 this is done using ConsoleOne. First connect to the NDS tree, and then to the NFS server.

When you add the exports you can tell from which machines the root user will have root access to the

ﬁles (similar to no_root_squash on UNIX systems). In Netware 6.5, this conﬁguration is instead done

via iManager - using ConsoleOne won’t work.

If you read users and groups from NDS (by using nss_ldap ) you should add a group, for instance

unixusers . In the group settings you should set the GID in the UNIX -tab. Then you add your users to

the group. You should also make sure that the Admin user has UID 0 set in the UNIX -tab.

To get ﬁle locking you need to run the lock ﬁle daemon. You can start it with the command:

$ load lockd

You probably want to add this to your startup ﬁles to make sure that it’s running from start. Also note

that if you are running ZENworks for Desktops, you want to change the load order in AUTOEXEC.NCF so
