Perl script to mount iso file

BerSerK has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I want to create a simple web page that lists the ISO files I have in a directory so I can select one file and click a button to mount that file in a preconfigured directory. I'm stuck at mounting the file with perl, I need sudo and I don't know if it's possible to do that from a script. I basically have a php file outputting a form, on that form I select what file I want to mount and click 'submit', I post the info to /cgi-bin/discmount.pl. Dismount.pl should mount to /media/vdrv0 which is shared by samba. Anyone can help me with the mounting part if it's possible ? Thanks

If you only need one mount at a time, you could add an entry to your /etc/fstat like this: `/tmp/isofile /tmp/isomnt iso9660 user,loop 0 0` [download] Which allows you to mount /tmp/isofile as /tmp/isomount without being root. You can then simply symlink the .ISO file to /tmp/isofile when you need it. Note that you probably should pick a safer place than /tmp.

I only need one mount at a time but how could I change which iso file is mounted from my php form...I would have to copy the desired iso file to /tmp/isofile each time ?	[reply]

Like I said, you can make a symlink, either from the perl script or from the php page. Just make sure that isofile node is a symlink to the file you want to mount before mounting. See symlink "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply]

#I need sudo and I don't know if it's possible to do that from a script. Yes, you can. sudo has a NOPASSWD option. Check the sudoers manual here.	[reply]
