This section describes the files that are added or changed during the process of installing the 1.2 Sun Network CoProcessor Software.
---------------------------------------
usr/etc/necons usr/etc/neload usr/etc/nestat usr/etc/nestop usr/etc/newatch usr/etc/sncnet usr/etc/snc_nfsd usr/man/man4/ne.4 usr/man/man8/snc_nfsd.8 usr/man/man8/neload.8 usr/man/man8/nestat.8 usr/man/man8/nestop.8 usr/man/man8/newatch.8 usr/man/man8/sncnet.8 usr/man/man8/MAKEDEV.ne.8 dev/MAKEDEV.ne etc/reload.ne0 etc/reload.ne1 etc/reload.ne2 etc/reload.ne3 etc/reload.ne4 etc/reload.ne5 etc/reload.ne6 etc/reload.ne7 etc/ne.dwnld sbin/neload sbin/sncnet sys/nfs/nfsagent.h sys/sundev/nereg.h sys/sundev/ne_conf.c sys/sun4m/OBJ/ne.o sys/sun4m/OBJ/nfs_sncsvr.o sys/sun4m/OBJ/sncnet_vers.o var/tmp/unbundled/SNC/deinstall_snc var/tmp/unbundled/SNC/snc.newfiles var/tmp/unbundled/SNC/snc.overwritten ---------------------------------------
In addition, files in sys/sun4m/conf may have been created based on user responses during the installation. These would be related to the changes needed to make a new, SNC compatible kernel. For more information on kernel configuration, please refer to the appropriate section in the System Administration Manual.
---------------------------
etc/rc.boot etc/rc.local usr/etc/arp usr/etc/nfsstat usr/man/man4/Intro.4 usr/man/man4/List.4 usr/man/man4/nfs.4p usr/man/man8/Intro.8 usr/man/man8/List.8 usr/man/man8/nfsstat.8c sys/conf.common/files.cmn sys/sun/conf.c sys/sun4m/OBJ/if.o sys/sun4m/OBJ/in.o sys/sun4m/OBJ/route.o sys/sun4/OBJ/if.o sys/sun4/OBJ/in.o sys/sun4/OBJ/route.o ---------------------------
For each of the above files, the installation script retains copies of the original files in renamed files of the form "name.presnc". Do not move, rename or change these files for any reason. If you do, then the deinstall_snc script will not work properly.
The installation script edits specific files. The CD-ROM contains several "dot- add" files (so called because the file names are in the form of *.add.*). Each of the *.add.* files contains text to be added to an existing file, and comments which tell you exactly where and how to perform the required edits.
The following is a list of system configuration files that you must edit by hand if you do not allow the installation script to do it automatically:
--------------------------------------
etc/rc.boot Snc/_install/SNC/rc.boot.add.nc.a etc/rc.local Snc/_install/SNC/rc.local.add.nc.a Snc/_install/SNC/rc.local.add.nc.b sys/sun/conf.c Snc/_install/SNC/conf.c.add.nc.a Snc/_install/SNC/conf.c.add.nc.b sys/sun4m/conf/GENERIC_SNC Snc/_install/SNC/config.add.nc.a Snc/_install/SNC/config.add.nc.b sys/sun4/conf/GENERIC_SNC Snc/_install/SNC/config.add.nc.a Snc/_install/SNC/config.add.nc.b sys/conf.common/files.cmn Snc/_install/SNC/files.cmn.add.nc.a --------------------------------------
When you wish to reconfigure your system the *.add.* files will contain the necessary substitutions for the corresponding file.
For example:
Substitute the lines in conf.c.add.nc.b for the existing tm entries (major device number 5) in the cdevsw table for sys/sun/conf.c:
(old lines)
-----------------------------------------------------
tmopen, mclose, tmread, tmwrite, /*5*/ tmioctl, nulldev, seltrue, 0, -----------------------------------------------------
(new lines)
------------------------------------------------------
/* Sun Network CoProcessor */ neopen, neclose, neread, newrite, /*5*/ neioctl, nereset, neselect, nemmap, ------------------------------------------------------
If you want to remove the software installed for the Sun Network CoProcessor, you are provided with a script to help you. Following your execution of the cdmanager installation procedure for SNC, a file will be left in the /var/tmp/unbundled/SNC or the /usr/tmp/unbundled/SNC directory called deinstall_snc. To remove the SNC software, simply cd to the appropriate directory and execute this script as Super-User. If you have cleared this directory, then the deinstall_snc script may also be found on the SNC distribution CD-ROM in Snc/_install/deinstall_snc and it may be executed directly from there.
After executing this script, you'll want to do the following:
The deinstall_snc script does not do this automatically because of the probability that you may have other products installed on your system that may have used the original SNC configuration file as their starting point. As such, your local System Administrator should know what changes need to be preserved. Note however, that de-installing the SNC product removes the associated device driver files, so at the very least, you will need to remove the references to the ne devices from your config file.
This is contained in the root ( / ) directory. Your SNC kernel will still work. It will just be a little larger (by the size of the SNC driver code). This will reduce the amount of memory that is available to your users.
/etc/hostname.xx# files that are used at boot time to bring up the different network interfaces.
If you did not disable your on-board le0 interface during your original installation, then you should be able to:
# rm /etc/hostname.ne*
Then make sure that /etc/hostname.le0 contains the name that you want the network to recognize your host as.
Alternately, if you've substituted one of the SNC boards for your on-board le0 interface, then you would:
# mv /etc/hostname.neX /etc/hostname.le0
# rm /etc/hostname.ne*
where "X" is the number of the SNC interface that was responding to your original hostname.
