RE: su command failing on RHEL5

[Sanjay Kumar]

That I have already checked.

address@hidden ~]# ls -ld /dev/tty
crw-rw-rw- 1 root tty 5, 0 Jun 13 00:32 /dev/tty
address@hidden ~]#

I have written, that after copying su executable from RHEL4 on RHEL5, it
is working. There must be some issue with coreutils-5.97. 

Thanks & Regards,

The su command appears to be working properly.  The problem shown
above is that your system is missing the /dev/tty device node.
Something has apparently removed it!  You can confirm this by running
the following.

  ls -ld /dev/tty

You could repair your system by creating that device node.  See the
'mknod' documentation for how.
