I do not have access to RHEL 5.2, but I do have an RHEL 5.6 machine.
It does not complain when I run:
echo hello | ssh -tt -oLogLevel=quiet redhat56 stty | cat
Can you reproduce it on a clean RHEL? Or even better: reproduce it on
a machine of which you are allowed to distribute an image?
Which of these give the 'tcgetattr' error:
echo hello | ssh -tt -oLogLevel=quiet g4t0930c stty | cat
echo hello | ssh -tt -oLogLevel=quiet g4t0930c cat | cat
echo hello | ssh -oLogLevel=quiet g4t0930c cat | cat
echo hello | ssh g4t0930c cat | cat
echo hello | ssh -t -oLogLevel=quiet g4t0930c cat | cat
echo hello | ssh -T -oLogLevel=quiet g4t0930c cat | cat
[... feel free to invent more combinations here ...]
I have the feeling that it is not stty that is causing the problem,
but rather the -tt. And if we can narrow it down to that, then maybe
we can find a solution that works for you, too.
