I'm still trying to figure this one out: after doing an apt-get upgrade a couple of weeks ago, I could no longer dialout unless I was root. Naturally, the first thing I do is check the permissions: lrwxrwxrwx 1 root dialout 10 Jun 20 2001 /dev/modem -> /dev/ttyS3 crw-r----- 1 root dialout 4, 67 Jul 9 19:54 /dev/ttyS3 Next, I check that user 'peter' is included in the group 'dialout'--yep. So why does wvdial say 'Cannot open /dev/ttyS3: Permission denied' and kppp just say that it cannot find the modem? I did not have this problem before, and a dist-upgrade yesterday didn't help anything. Suggestions welcome. :Peter
