Just look at me, $ id uid=1000(jidanni) gid=1000(jidanni) groups=1000(jidanni),20(dialout),24(cdrom),29(audio),1004(scanner) My latest addgroup was disk, so I wouldn't get error messages when eject(1)ing USBs. However $ find /dev |wc -l 5142 $ find /dev -group disk -perm -20|wc -l 4006 that gives me write permission to most of /dev.
By the way, those error messages were eject: unable to open `/dev/sda1' #if my id(1) is not in the group "disk", or eject: unable to eject, last error: Invalid argument #if it is. Either way, it still does its job. One has to be root to not get the annoying messages. System is debian 2.4.19-k7. Another item is I can switch groups with ease, $ newgrp disk $ newgrp dialout $ newgrp jidanni Password: ****** Sorry. Except for my own group, which fails when I give my login passwd... Maybe I didn't read the manual. But more exciting is when run in a emacs *shell* window, $ newgrp disk Segmentation fault $ newgrp dialout Segmentation fault $ newgrp jidanni Password: ****** Sorry. $ newgrp audio Segmentation fault $ reportbug -f newgrp P.S. even after doing # deluser user group #(PPS: can use addgroup this way but not delgroup!) the processes still have those privileges until they die. But I guess that is how the system is designed. -- http://jidanni.org/ Taiwan(04)25854780 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
