    hi ,
    trying to install a firewall in red hat 8. I downloaded one from smoothwall.org and is saved as an .iso file. I'm a newbie and am not sure how to go about reading or compiling this .iso file. I've done a bit of research and from what i gather i need to burn it onto a cd to read it, is this the case?? if so i have the problem that i have never used my cd burner in linux and don't have any compatible software for it.
    I also dowloaded the .tar.gz version of smoothwall but couldn't untar it. I feel a bit like putting my tail between my legs and snuggling up to windows, but would prefer to get my linux spurs.
    any help fellas

    You say you're trying to install a firewall "in redhat 8". Smoothwall is a standalone linux firewall and doesn't have anything to do with RedHat. If you're just trying to burn a Smoothwall CD to create a standalone firewall then you're on the right track. IPCop is another example of a firewall/router mini distribution.

    If you want to build a firewall for a PC running RedHat 8 you're barking up the wrong tree. To create on your existing RH8 machine use IPTables, the standard kernel supported firewalling system. I'd suggest using a front end rules generator like Shorewall if you don't know much about it. This will allow you to create a firewall on your PC.

    An iso file is just an image of a cdrom filesystem (iso9660). If you actually need Smoothwall you'll need to burn it to a CD. To do this you can use a GUI CD burning tool (xcdroast or similar - I'm not sure what comes with RH8 ) or cdrecord from the command line. To burn a cd you also need to have SCSI emulation support.

    You can mount an iso image using a loop device under linux but this isn't what you need to do.
    mount -t iso9660 filename.iso /mount_point -o loop=/dev/loop0

    As for the tarball:

    It's a .tar.gz meaning it's been tar'ed and then gzip'ed. To extract it the following will work:
    tar -xzf filename.tar.gz

    The x specifies to extract. The z specifies to gunzip first. The f specifies that you are supplying a filename.

    yeah you downloaded a seperate linux distribution, you could install a firewall from a small script or there's loads of gui programs like kmyfirewall or something
