    Dial-up modem works fine in root, but permission denied to ttyS0 when user tries


    Question about Vectorlinux - hope you don't mind, seeing as it's Slackware-based...

    I just reactivated an old dial-up account, and dusted down my very Linux-friendly serial Creative Modem Blaster.

    It dials up and connects perfectly for root, but when I log in as user, it shows me the finger and says permission denied to ttyS0 (or something very similar). I wondered if it was a file permission problem, so I logged in as root and gave /dev/ttyS0 read and write permission for everyone, but that didn't fix it.

    I stopped there, having thought that I'd better ask before causing any chaos!

    All ideas welcome... I'm sure it must be something easy, as it dials up so well as root. But I know the risk of surfing as root! Too scary.

    Thanks

    Dial-up modem root/user issue solved

    Thanks for your post Juan

    It is now solved, and exactly as you said - it's a group issue.

    Someone on another forum suggested I type this in root:

    usermod -G lp,floppy,audio,video,cdrom,games,scanner,users,tt y myusername

    (the tty doesn't have spaces, but in this forum there is a font display error which will not allow me to show these characters with no spaces when part of this string - very curious!)

    It worked perfectly...
