Re: define a default username for logging in
Hi again, Really Thank You for your tricky advice.. it was a Nice one(and seems to be the Only one!).. :) sorry for late reply; it took me a while to become sure i got no other ways that bothering you again.. the suggested way seems to work, but i've got a problem: how can i apply these settings on pts devices?! i mean, how can i disable login on pts devices to continue the rest? do you have any idea?? i tried the same format in /etc/ttys, but it didn't work.. i could not find any tips via googling as well.. so.. :) you know, it's not that important to be able to use all 999 enabled pts devices on my server! i can abound them if there is a file such as /etc/ttys for per pty device configurations.. looking forward to receive your ideas.

define a default username for logging in
Hi All :) i'm trying to find a way to enable a required feature : to set *default username *in my Freebsd 8.2 server.. i mean, i wanna be able to login with just entering My Master Password(no usernames needed.. also prefer it to be per tty), which is *not related to my root account, *but is the password of a user which i have defined as my default user.. is it possible for, e.g. pam_login module (i couldn't find any manuals on such feature yet..), to have such a config or is there any other ways to set such default username for login? i've googled most of the keywords i thought might be related, but haven't find any related answers except for maybe working on nsswitch.conf or master.passwd or login.conf options (which are, as you see, really *different ways, *and also none seems to be behaved per tty..) and now, i'm not quite sure whether i'm taking the correct steps or not.. and i've got a bit confused.. would anyone please helps me find the way? thanks a lot for your helps :) Best Regards, takCoder ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
