Hi Damien!

Thanks for the friendly reply!

I did a few more tests to investigate the matter further based on your
comments. The bottom line is, that the settings from the file
"environment" in the .ssh directory are not considered at all. The
values from the calling SHELL have precedence over the entries in the
file, which makes the file quite useless. Am I overlooking something

Best Regards
