running tar from a browser
Hello everyone.
Here is my problem, if anyone can please help me:
Running, Linux.
I am trying to write a simple backup program to backup the data from a
directory.
The script works from the command line.
But when I try to run the same script from the browser, it doesn't work.
I get this message:
Data could not be backed up.
Exited with the following message: No such file or directory
The error logs say:
tar: backup.tar: Permission denied
tar: Error is not recoverable: exiting now
Can anyone please help me?
Here is the contents of the script:
#!/usr/bin/perl
my
($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$size,$atime,$mtime,$ctime,$blksize,
$block);
my $command1 = tar cvf backup.tar members templates reviews;
system($command1);
($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$size,$atime,$mtime,$ctime,$blksize,
$block) = stat backup.tar;
my $DAT_SIZE = $size;
print Content-Type: text/html\n\n;
if (-e backup.tar) {
print CENTERH1Backup

You need to change directories. This is probably running from your
cgi-bin directory, which the web server doesn't have (or need) write
access to. Is cgi-bin where members, templates, and reviews are kept?
The directory you switch to must be writable by the web server in
order to create backup.tar, or you will have to specify a directory
that *is* writable.
