Hi,
still having problems (starting with kernel 2.4.12) with
the /dev/tty device:
When logging in on the console and trying the "ps" command,
is will list _all_ processes and not only those which are
attached to the controlling terminal. This seemed a little
bit suspicious.
Now, trying
echo some text >/dev/tty
returns
bash: /dev/tty: No such device or address
Now trying the command
tty
says
/dev/tty1
Now, I tried
echo some text >/dev/tty1
It echoed correctly
some text
on the console.
Then, I tried
echo some text >/dev/tty
Now (!!!???) it echoes correctly "some text".
It seems that the cmd
echo some text > `tty`
will repair something, but I don't no what and why.
-----------------------------------------------------
The above described problem first appeared with Kernel 2.4.12,
I tried the following kernels (now 2.4.16), BUT WITH NO SUCCESS.
Kernel 2.4.10 was _not buggy_.
Additionally, the problem does not arise on all my LINUX workstations,
but only on some. And it does not depend on the harware platform.
And is does not depend on the distribution. Both on RedHat 7.1 ans
Redhat 7.2 having the problem.
Regards
Joachim Backes

Do you have devfs? In that case the Devices are generated dynamically.
If you run ls on /dev/tty you should see an Entry with major 5 and minor
number 0.

ls -l /dev/tty
crw-rw-rw- 1 root root 5, 0 Nov 27 08:21 /dev/tty
/dev/tty was never missing!

I also tested my 2.4.10-17 for tty bug,it was there.And I found that bug
exists if I do the full installation of our distributive.

I believe it's a problem with /bin/login, which has a race condition
preventing it from opening /dev/tty. It is fixed in rawhide, upgrading
util-linux to at least 2.11f-6 solved this for me.
So it's not a kernel issue.

Thanks, this helped me a lot. Only one issue: after installing rawhide vers. 2.11f-16
of util-linux and not 2.11f-6, my problem disappeared.

Yes, yes. My mistake. I must've been hungry when writing that, because
I simply ate the '1'. :-) Sorry.
