Terminal in 10.3 denies permission

[James Bee]

I seldom use terminal, but have successfully used it with the hdiutil command to burn .iso CD's. Now when I try to use it, no commands work at all, I get an error message that says "permission denied." BTW, 10.3 disc burn doesn't work to create a disc image from an iso, which is why I began using terminal--that seems like my only option.
Please help.

try typing "su yourusername" without the quotes. Then enter your password. Hope that helps.

I beleve he meant sudo yourusername or just su.

Using su yourusrrname will log in to your own your account.

Thanks. su username felt like progress, as the password prompt came up on the next line (I've been getting no response at all, except "permission denied." But when I type in my password, the cursor doesn't move, and I get a reply of "sorry". I've tried the password several times. What else might it be?
