In trying to upgrade our operating from Sun OS 3.4 to 3.5, I have encountered the following strange problem. On most of our clients, logging in via the console is impossible because whatever user name (including root) you give, after hitting the carriage return no password is asked for, but instead a new login prompt is generated. When logging on remotely, no problems are seen at all and normal password procedures are followed. A further clue is after four or five attempts to login at the console, a message appears saying something like: init /dev/console getty sleeping Anyone have a clue as to what is going on here?

A guess... Passwords are read from /dev/tty. Check to see if it is a really a device. Should look like this. chris@gargoyle 1 ls -lg /dev/null /dev/tty crwxrwxrwx 1 root wheel 3, 2 Jan 10 22:15 /dev/null crw-rw-rw- 1 root wheel 2, 0 Jan 10 22:16 /dev/tty chris@gargoyle 2 file /dev/null /dev/tty /dev/null: character special (3/2) /dev/tty: character special (2/0) cj
