 ? unsure what you're unsure about -- the instructions given in last mail 
should (no - will) give you suid capabilities for the script given in the 
system command. system() will invoke the command passed into it (in your 
case, /usr/local/httpd/cgi-bin/test.cgi) via /bin/sh. I am assuming you've 
copied the wrapper program into /usr/local/httpd/cgi-bin, and you've tried 
running the wrapper via http (ie, http://your.server/cgi-bin/cgi-wrapper ... 
where cgi-wrapper is whatever you decided to call it). Try typing "man 3 
system" and see if that helps.

I don't know any good books or web sites (not teach-yourself ones) ... I 
taught myself C with Turbo C V2.0 from Borland, using nothing much mroe than 
the help screens, and UNIX with the man pages and also the book "Newnes UNIX 
Pocket Book", which *is* a good book, but its more a reference than a 
teach-yourself (I prefer learning from reference books ... the hold their 
usefulness beyond the "teach yourself" phase).
