Hi,
I'm trying to create a module that allows users to write a .forward file in their home-dir from a webpage. Basically a module that a user can use to get sendmail to forward their email.
The problem I have is that the code works on my Windows machine, however when I port the code to my Linux server, the code appears to work, the file is never written.
Not only can I not seem to write it to a users home directory, I can't get it to write the file at all when the code is executed from the webpage. However, I created a command line version of the code and that works just fine.
I have tried various combinations of the code including:
a) having a .forward in the users home directory that is created and owned by the apache user who has read and write access.
b) Changing permissions on my perl scripts dir so that the directory is owned by the apache user
c) trying to write to a directory that is created and owned by the apache user.
I suspect this has something to do with perl security, can anyone help me? Also, if this wont work, can someone suggest a script or an other way of creating a web-based user interface that allows users to configure sendmail to forward email.
I AM USEING PERL 5.6.0 on my Linux box
(It works on windows which runs 5.8.0 but I dont think this is the reason).
All help is appriciated.
My perl code is below:
#!/usr/bin/perl
use Fcntl;
print "Content-type:text/html\n\n";
print "hello world";
if ($ENV{'REQUEST_METHOD'} eq "GET") {
$request = $ENV{'QUERY_STRING'};
} elsif ($ENV{'REQUEST_METHOD'} eq "POST") {
read(STDIN, $request,$ENV{'CONTENT_LENGTH'})
|| die "Could not get query\n";
}
@parameter_list = split(/&/,$request);
foreach (@parameter_list) { # split each va
+riable=value pair
($name, $value) = split(/=/);
$name =~ s/\+/ /g; # replace "+" w
+ith spaces
$name =~ s/%([0-9A-F][0-9A-F])/pack("c",hex($1))/ge;
# replace %nn w
+ith characters
$value =~ s/\+/ /g; # repeat for th
+e value ...
$name =~ s/%([0-9A-F][0-9A-F])/pack("c",hex($1))/ge;
if (!(defined $passed{$name})) {
$passed{$name} = $value;
} else {
$passed{$name} .= ":$value";
}
}
#print "$request";
#print "$passed{'username'}";
#print "<br/>$passed{'Submit'}";
print "<br/>";
print "<input type=submit name=Back value=Back onClick='Javascipt:hist
+ory.back(0);'/>";
$file = ".forward";
#$file = "/home/$passed{'username'}/>.forward";
#$file = "c:/$passed{'username'}/.forward";
print "<br/>$file";
if($passed{'Submit'} eq "Submit"){
if($passed{'mforward'} eq "on"){
print "<br/>turn mail forward on";
sysopen (FWD, $file, O_RDWR|O_EXCL|O_CREAT, 0644);
if($passed{'rcopy'} eq "Yes"){
printf FWD "\\$passed{'username'}\n";
}
print FWD "$passed{'faddress'}";
close (FWD);
print "<br/>Mail Forwarding ON mail for: ";
print "$passed{'username'} forward to $passed{'faddress'} <br/
+>";
print "$passed{'rcopy'} Copy Retained!";
} else{
print "<br/>turn mail forward off<br/>";
if (unlink($file) == 0) {
print "Forward Removed";
} else {
print "ERROR Forward NOT REMOVED";
}
}
} else {
}
