The experimental download package requires Solaris 9 Update 5 (12/03).
This is explicitly mentioned in the README file, SYSTEM REQUIREMENT
section. Install it in other kernel version will cause the problem
you are having. The reason is that there are changes in the IP module
in Solaris 9 Update 5. So the module provided in the experimental
SCTP package has to match that version.

What you can do is to replace the ip modules in /kernel/drv/ and
/kernel/drv/sparcv9/ with the original modules. The original modules
should be saved in the same directory by the SCTP package install
script. Do the same thing to sockfs modules in /kernel/drv/ and
/kernel/drv/sparcv9/. Also replace the /etc/sock2path with the
original one, it should also be saved. This should allow you to
boot up the system again. Then you can do a pkgrm to remove the
package.

Please update your system to Solaris 9 Update 5 (12/03) before
installing the SCTP experimental package again. Many customers have
successfully installed this package and testing it.

Hi Kacheong,

Thanks very much for this info. Indeed the 'preremove' script that comes
with the SUNWsctp package does exactly this (i.e. copies the original
versions of kernel modules back to their original place - whew

Out of curiosity do you know whether a third party IPSec module might cause
problem with the SCTP implementation (associated with a Cisco VPN Client).

Thanks and regards,
Andrew
