1) Can my customers use cgi to harm my system

Yes, if you done use SuExec.

2) Can my customers use shell access to harm my system

Yes. I would not give users shell access unless you recompile your SSHD to ebale chrooting of shell users and create chrooted accounts for your shell enabled users.

Olease have a look at this howto:

IF not to both how do I use it and set it up

Thanks

No. But you can enable suExec in ISPConfig under management > server > settings.

I dont know of a howto for SuSe for chrooting SSH users. Maybe google a bit or try to adapt the DEBIAN howto.

During ISPConfig installation you must specify /srv/www as ISPConfig's document root instead of /home/www because SuSE's suExec is compiled with /srv/www as document root. Have a look at the suExec section on http://www.howtoforge.com/perfect_setup_suse_9.3_p6
And then, you have to enable suExec in ISPConfig, as Till said.

OK.. thanks... small problem though can I re-run the SuExec and specify that /home/www is the default folder... or change a config file somewhere.... rather than re-installing ISPC to change the web folder.

Thanks

SuExec is compiled into apache, it is not configured in a config file. If you dont want to change your web root you will have to recompile your apache webserver and set the correct web-root as configure parameter.
