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.

The problem shown above is that your system is missing the /dev/tty device node. If the file were missing, you would get ENOENT. ENXIO only means that the underlying device does not exist. That can either mean that /dev/tty has the wrong device address (major/minor device number), or that the process has no controlling terminal.

Hello, Sanjay Kumar wrote: [r...@omvm6 ~]# su poo -c cat /dev/tty cat: /dev/tty: No such device or address open(/dev/tty, O_RDONLY) = -1 ENXIO (No such device or address) 1) su command is not failing 2) cat is working as expected su -c creates new process in RHEL-5 - which is expected behaviour as it could cause security problems. This process has apparently no controlling terminal /dev/tty. There was non-upstream longoption --session-command added in RHEL-5 to restore RHEL-4 behaviour. Consider using it in this case. Please let us know the fix available or not. Next time it would be better to use RHEL product support or RedHat bugzilla. Please try to use it instead of upstream mailing list, if --session-command is not solving your issue.

RE: su command failing on RHEL5
That I have already checked. [r...@omvm6 ~]# ls -ld /dev/tty crw-rw-rw- 1 root tty 5, 0 Jun 13 00:32 /dev/tty [r...@omvm6 ~]# I have written, that after copying su executable from RHEL4 on RHEL5, it is working. There must be some issue with coreutils-5.97.
