can't login from anything other than the console

can't login from anything other than the console

[Chris Peterson]

Hi blinuxers!

Perhaps someone can give me some advice here.  I just installed Redhat 5.0
and everything works great.  I have the dumb terminal connection to my dos
machine working properly and I get a login prompt and my keystrokes are
getting from the dos box to the linux box the right way up and so on.  So
here's my problem...

>From the console login prompt I can login as root and everything is just
fine except that I can't do much without speech and I'm not up to the point
where I'm ready to install emacspeak yet.  When I try to login from the dos
terminal, though, I always get a "login incorrect" message.  My other linux
machine is a slackware machine and I've never encountered this before.  Any
ideas?

thanks,
Chris

At least on my system, a file called /etc/securetty determines which ttys
are allowed to login as root.  If your dos box is connected to com1, you
can try logging in as root from the console and typing
echo /dev/ttyS0 >> /etc/securetty

In order to be able to log in as root from any  device other than the
console, you need to add that device to the securetty file.  Just add
/dev/ttys0 (or whatever it is you're logging from) to that file, and
you'll be fine.

All redhat VS slakware quips aside: check your "/etc/securetty" file.
If your terninal's port is not listed therein, then you won't be able to
do root logins on it.

Chris,

I found a simple way around this one.  Log into the console as 'root'
and create another account for yourself.  When you want to be 'root'
from your terminal, login with the new username and do a "su" from the
prompt.  When you've given the root password, you'll have 'root'
privileges from the terminal.  I, too, didn't need to do this with
Slackware.
