Problem with ssh commands in bash

[bgk111]

Hey all, Ill try to keep this short. I am trying to issue a command to another computer using ssh (ex ssh user@host 'csh /home/usr/SCRIPTS/tp.csh) and am getting some annoying error messages. when I run the tp.csh program on the host machine, it runs fine, when I issue the above command from a remote computer, I get 2 different errors:

TERM environment variable not set

and

error while loading shared libraries: libcudart.so.2: cannot open shared object file: No such file or directory

I cant really go much in to the what of the code as I cant show it. I DO know that I can re-create the first error using the following command:

ssh user@host 'top -u user'

I have heard that the top problem can be fixed by running in batch mode, but need to find a way to get the functions working without that. Is there a flag in ssh im missing? I feel like if I can fix the TERM big (both computers display xterm when I issue the command echo $TERM), then I can fix the other library problem using the same method. Any ideas? Thanks for your time!

At the target machine, in the .ssh/environment add BASH_ENV=.profile (assuming bash as a default shell and the standard setup). Otherwise, many important variables, such as TERM, LD_LIBRARY_PATH, etc, etc would remain undefined.

hm, i am likely being dense but im still having a problem, so didnt have a .ssh/environment file, so I created one in that area using emacs. I get the following now:

~>cat .ssh/environment
BASH_ENV=profile
~>
and when I run the code, im still getting the same error. I am trying to do some googling but must not be looking for the right thing. I see that there is something in that has to do with bash, a file called profile. I dont know where it is but maybe I need to fix something additional? I should mention I am not root on either machine, but can ask root to make changes as well if they need to make changes. Thanks for all your help so far.

FYI, I found a temporary tho non-ideal solution, I can do the following and all works well:

ssh usr@host "export TERM=xterm; export LD_LIBRARY_PATH=LD_LIBRARY_PATH=/opt/intel/Compiler/11.1/064/lib/intel64:/usr/local/cuda/lib;csh /home/path/tp.csh"

I would love to find a better solution tho along the lines we are discussing above.

> BASH_ENV=profile

It is [B].[/B]profile . The dot is rather hard to see, so it is dot-profile.

[bgk111]

ok, I added the . to profile and now have:

~/.ssh>cat environment
BASH_ENV=.profile
~/.ssh>

I still get the same errors and when I do an ssh usr@host 'env' command I am missing the same environmental variables. I wonder if it has to do with needing to add PermitUserEnvironment to the /etc/ssh/sshd_config file, which I will need to ask my admin to do. Do you think this would help?

What is there in your .profile? It usually defines and exports all the necessary environment variables. If it does not, add them there.

~>cat .profile

# ~/.profile: executed by the command interpreter for login shells.
# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
# exists.
# see /usr/share/doc/bash/examples/startup-files for examples.
# the files are located in the bash-doc package.

# the default umask is set in /etc/profile
#umask 022

# if running bash
if [ -n "$BASH_VERSION" ]; then
    # include .bashrc if it exists
    if [ -f "$HOME/.bashrc" ]; then
        . "$HOME/.bashrc"
    fi
fi

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

And for the possible next question, here is .bashrc

    if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then
        # We have color support; assume it's compliant with Ecma-48
        # (ISO/IEC-6429). (Lack of such support is extremely rare, and such
        # a case would tend to support setf rather than setaf.)
