<DIV><FONT face=Arial size=2>On setting up U,G,O permissions on a my website
hosted at an ISP....</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Q's arising:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1. What permissions for me to do necessary
tasks, and allow external Users http access - but exclude external Users from
doing nasty or deliberate stuff(ups)? Can they be prevented from
reading site files but still do http?</FONT></DIV>
<DIV><FONT face=Arial size=2>
<DIV><FONT face=Arial size=2> My logic
is User is an "other" and only needs
r access (someone has told me they only need x
) ?</FONT></DIV> </FONT></DIV>
<DIV><FONT face=Arial size=2>2. An external ISP User needs to fill
in a data form that calls a Perl script from cgi-bin. The perl
extracts the data and stores it in a file in another directory. What
permissions on the html file and what on the perl&dir and what on the
file&dir? Neither the User or any other should be able to access that
file. Remember this is hosted at an ISP, and I am only be a member of
that site.</FONT></DIV>
<DIV><FONT face=Arial size=2> My logic
(where a=any .=none and rwx=normal) is:</FONT></DIV>
<DIV><FONT face=Arial size=2>
html file&dir ugo=
aaa ... x.. or aaa ... x.r
?</FONT></DIV>
<DIV><FONT face=Arial
size=2> perl&dir ugo=
xaa ... ... ?</FONT></DIV>
<DIV><FONT face=Arial size=2>
data&dir
ugo=awr ... ... ?</FONT></DIV>
<DIV><FONT face=Arial size=2>Script will need to write data entered by user to a
file in another directory but no-one should not be able to re-access
it.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>3. What about telnet, ftp and
other prevention on same setup?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Regards to all,</FONT></DIV>
