openssh unix dev - Oct 2007 - Fw: about the "locale" command

hello everybody,
I am writing to you since you (or some one in you team) surely have more
experience than me with "locales".

Thanks in advance if you can help me.



I  am doing a test with two Linux hosts  running the bash:

GNU bash, version 3.00.15(1)-release (i386-redhat-linux-gnu)
Copyright (C) 2004 Free Software Foundation, Inc.

Now, when I locally run the "locale" command, on both the two machines
(say: "host1" and "host2") I get the following:

LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL

Now , if I run the "locale" command from remote by using openSSH (from
another linux box more or from Cygwin), like this:

ssh -p 22 root at host1 locale

I get:

LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL

from the host host1.

On the opposite I get:

LANGLC_CTYPE="POSIX"
LC_NUMERIC="POSIX"
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MONETARY="POSIX"
LC_MESSAGES="POSIX"
LC_PAPER="POSIX"
LC_NAME="POSIX"
LC_ADDRESS="POSIX"
LC_TELEPHONE="POSIX"
LC_MEASUREMENT="POSIX"
LC_IDENTIFICATION="POSIX"
LC_ALL

from host2.





The question is: why is this difference and how can I fix host2 in order to
produce the "correct" locale output (i.e.: to produce the same locale
as
when I run from locally)?


Thanks for helping,
Davide.

Maybe it just doesn't support utf8 locales.

I would guess that's the case if host2 is the Cygwin system, but
that's just a FUD guess. :p

Notice that LANG is reported without quotes while the others are
reported with quotes?  This is a hint.  When a variable is set the
locale command does not report it with quotes.  When the variable is
inferred by the presence of a set variable then it is quoted.  So here
I can see that LANG is set to en_US.UTF-8.

Here I can see that LANG is not set.

I suspect that in the host1 ~root/.bashrc file that LANG is
explicitly set to LANG=en_US.UTF-8 and on the other host that it is
not.  The bash shell tries to guess when it is being run by a remote
shell non-interactively and sources ~/.bashrc in that case.

Depending on how sshd is installed and configured on your system it
may be setting LANG through /etc/environment or /etc/default/locale or
/etc/default/ssh or other system specific location.  It is usually
installed with PAM and therefore PAM configuration applies too.
