Distribution: Redhat 9.0.93
Hardware Environment: Sony GRX600 laptop
Software Environment:
Problem Description:

I use ssh to remotely execute a command, that requires standard input to appear
as a file. The standard way is to access /proc/self/fd/0. A typical use is:

$ find / | tar cf archive.tar -T /proc/self/fd/0

the problem can be fixed by inserting a 'cat |' before the command requiring
standard input as a file.

Steps to reproduce:

$ echo Hello | ssh localhost 'cat /proc/self/fd/0'
cat: /proc/self/fd/0: No such device or address
$ echo Hello | ssh localhost 'cat | cat /proc/self/fd/0'
Hello
$

Not only is that 2.4, not 2.6, it also seems to be a distro kernel.
Moreover, there's no indication it's a kernel problem from your description.
Suggest you file this in some distro bugzilla somewhere.
