Redhat linux command to check Version

Hi All,

I need to know RedHat linux version installed on a different servers.
I know uname -a or /proc/version
Is any other command to know the Linux version????

When we telnet to any of the Linux server, the version shows very clearly like
Red Hat Enterprise Linux ES release 3 (Taroon Update 6)
Kernel 2.4.21-37.ELsmp on an i686
login:

In similar way can we find same info when telnet service is not enabled?

Thanks & Regards,
Bachegowda

SWITCH_ROOT(8)						       System Administration						    SWITCH_ROOT(8)

NAME
switch_root - switch to another filesystem as the root of the mount tree SYNOPSIS
switch_root [-hV] switch_root newroot init [arg...] DESCRIPTION
switch_root moves already mounted /proc, /dev, /sys and /run to newroot and makes newroot the new root filesystem and starts init process. WARNING: switch_root removes recursively all files and directories on the current root filesystem. OPTIONS
-h, --help Display help text and exit. -V, --version Display version information and exit. RETURN VALUE
switch_root returns 0 on success and 1 on failure. NOTES
switch_root will fail to function if newroot is not the root of a mount. If you want to switch root into a directory that does not meet this requirement then you can first use a bind-mounting trick to turn any directory into a mount point: mount --bind $DIR $DIR SEE ALSO
chroot(2), init(8), mkinitrd(8), mount(8) AUTHORS
Peter Jones <pjones@redhat.com> Jeremy Katz <katzj@redhat.com> Karel Zak <kzak@redhat.com> AVAILABILITY
The switch_root command is part of the util-linux package and is available from https://www.kernel.org/pub/linux/utils/util-linux/. util-linux June 2009 SWITCH_ROOT(8)
