[I'm in the process of updating this (1995.09.26) so things are going
to be a little chaotic until I'm done; hopefully soon --Chris]
Setup and configuration
These notes indicate the steps we went through to bring new SGIs out
of the box, format and partition for our needs, set up networking,
filesharing, and in some instances, use NIS for sharing account
information. It then talks about some security concerns, and also
describes how we set up our NFS sharing.
- Format and partition the disk:
- SGI ships their systems with single / partitions; we prefer
to format into separate partitions, eg: /, /usr,
/var, and swap. When upgrading from Irix-4.0.5 to
Irix-5.3, I found it cleaner to reformat the disk than try to upgrade.
- Install system software:
- Install default and customized configurations of the software from
the distribution CDROM.
- Protect accounts:
- SGI ships with a number of accounts which have no passwords; these
pose a threat to your machine, especially once it is on the
net. Close off this avenue of attack now.
- Basic network setup with EZsetup:
- Set basic Internet parameters such as hostname and IP address.
- Finish configuring the network:
- Configure other networking parameters such as netmask and
broadcast address, default router, and domain name service
- Close some network security holes:
- There are some problems in the SGI default network configuration
that puts your machine at risk.
- Some important miscellanea:
- Set the proper timezone, build whatis database for
- Set up NIS to share account information
- Share passwd, group, and alias files; configure the visual login
screen to display non-local, NIS accounts.
- Set up SYSV printer
- You can set up a machine with a locally-attached printer as a
server for the network. Client machines access it via SYSV network
printing system. I've also got an icky hack to allow BSD systems
to access the SYSV printer over the net.
Tweaks, fixes, and improvements
Formatting local man pages
- SGI's stock man does not format man pages -- the
nroff suite was "unbundled" and all SGI man pages come
preformatted. This means you can't use man to view your
locally-added, unformatted man pages, like those you might might
install in /usr/local/man. SGI has a replacement
man on their FTP server at
ftp://ftp.sgi.com/sgi/IRIX5.0/man/ -- here's the README.man file. I don't like replacing
system files, so I may look for some other solution, possibly
- Replacing stock mrouted
- The mrouted that comes with Irix is the obsolete 2.2
version which apparantly does not support pruning and doesn't
support bandwidth limiting. Without the later, the mrouted
traffic hosed a 56Kb network at one site. You can get
Old, obsolete, or in transition
