Useful tools for Sun workstations and Solaris
This page is no longer being maintained. It is still here in case it might be useful to somebody, but many of the links are broken, much of the software
obsolete, and it is generally in a state of disrepair.
change-sun-hostid is a
collection of C programs and scripts for systems administrators which allow one
to change the real or apparent hostid of a Sun workstation. In addition there is
support for changing the hostid of a PC running Solaris 2.5. This public domain
software is intended for short-term use in emergency situations, where the
hostid needs to be spoofed because a computer system goes down and some of the
applications must be moved to a different server immediately, i.e. without
waiting for the vendor to supply new keys. Software vendors rarely supply keys
outside of business hours, and they often take several hours or days to provide
new keys in the case of server failure. I'm working on a release for Solaris 7, most
of the programs in 1.7.4 about will work on 32 bit Solaris 7 systems. Here is a version of hid2 for 64-bit Solaris 7 systems Thanks to
Dale Higgs for compiling this using the new Workshop 64-bit compiler.
Available as of July 1997: some unsupported notes on changing the
system ID on IRIX machines.
The Sun NVRAM/hostid FAQ answers
frequently asked questions on comp.sys.sun.hardware and comp.sys.sun.admin about
the hostid and NVRAM/IDPROM chips on Sun workstations. These chips often fail,
and this FAQ will tell you how to repair your workstation for about US$20. As a
side-effect, this document also tells how to change the hostid and default
ethernet address of a Sun workstation. A
plain text version is available for folks
who find the
HTML version inconvenient.
Unstrip is a program that
allows one to recover some symbolic information from stripped dynamically linked
binaries under Solaris 2.4-2.6. This is occasionally useful for reverse
engineering and system debugging (here's an example).
Unstrip for Sun OS 4.1.x by Paul
Kranenburg is also available.
Steinar.Haug@nethelp.no is a kernel loadable module which will allow a Sun
running Sun OS 4.1.x to have multiple loopback interfaces with different IP
addresses. With the appropriate routes, one can effectively serve multiple IP
addresses. This can be used with
change-sun-hostid to make some
applications running on a machine believe they are running on a system with a
different hostname and IP address.
red.c allows one to generate ICMP host redirects from
arbitrary source addresses. This is useful for testing whether your
network is vunerable to disruption by ICMP redirects and to demonstrate
to folks why it is essential to either block these at routers or configure
hosts so that ICMP redirects are ignored.
It should work on Solaris 2.5 and 4.4BSD based systems.
