An analysis of Solaris 8 Startup Files pr0
Post Page Rank

Any installation of loads many packages that are not needed for a to function. However, even if you remove unneeded packages, there are several startup services which can be disabled. As part of your minimalization , you want to reduce number of processes and services running on your . Some of these unneeded services can pose a potential security risk. There are two main places to configure which services are active: the /etc/inetd.conf file and the /etc/rc.X/ directories.

inetd.conf
This file specifies which ports the inetd daemon will listen for. You eliminate uneccessary services by commenting them out. There are many web tutorials on configuring the inetd.conf file.

rcX.d services
/etc/rcX.d contains startup and shutdown scripts. (The startup scripts start with “S”, the shutdown with “K”. The standard recommendation is to rename the uppercase S to a lowercase one

The following table displays each of the Startup files, where they are placed, and which distribution and package they are part of. (I left out the “K” files for brevity. A list of resources which recommend which scripts can be disabled follows):

Notes:

  • The above table assumes that you’ve performed a standard SUNCWreq, SUNWCuser, SUNWCprog or SUNWCall install.
  • Therefore, any scripts belonging to the SUNWCXall metacluster installed on your system (such as S75flashprom) may be necessary for your system’s functioning and should not be deleted without careful consideration.
  • Therefore,carefull examine your system before following checklists or scripts which “delete all files except the following”…
  • The packages listed are representative; some of the startup files may be created from more than one package. (Perhaps I should have listed the cluster the package belongs to…)
  • The vast majority of startup files belong in the SUNWcsr (Core ) package which is installed as part of every installation. Others may not be created depending on which OS group and packages installed on the system.
  • Third party may install additional startup files.
  • Files in /etc/init.d are links to these files and usually are named the same but without the “Sxx” prefix.

 

Many of these scripts need to be disabled, some need to be modified, and a few need to be created.

Which ones can be disabled?
Unless you are absolutely sure, don’t delete a startup file, just disable it. There is a difference between deleting a file and preventing them from starting up…

If sure are sure you don’t need a file, then change its name or move it to a subdirectory called “disabled”:

    mkdir /etc/rc1.d/disabled/
    mkdir /etc/rc2.d/disabled/
    mkdir /etc/rc3.d/disabled/
    mv -f /etc/rc2.d/S*asppp /etc/rc2.d/disabled/
