[FreeNX-kNX] functions defined in /etc/profile.d/* are not set in nx session

[Urs Beyerle]

Hi

I have investigated a little bit further. The problem occurs because
functions and also aliases defined in the /etc/profile.d scripts are
normally not exported. In case of functions a "export -f functionname"
in the /etc/profile.d script would help. However, in case of aliases
they can not be exported.

In contrast to a "simple" ssh session, a nx session starts an
application (like startkde) within the nxnode script. Somehow functions
and aliases are not passed to the started application - they are lost.
Unfortunately, the scripts inside /etc/profile.d/ are only sourced once
and only in case the shell is a login shell. This is at least the case
for SuSE. I tried to fix this problem in the nxnode script, but had no
success.

At the moment I have the following workaround:
Under SuSE all shells are sourcing the files /etc/bash.bashrc.local (for
bash etc.) or /etc/csh.cshrc.local (for csh, tcsh). In these scripts I
check first, if it's a nx session. If yes, /etc/profile.d are sourced
(again). See the source code of the scripts below.

Maybe this problem is only SuSE specific and does not occur on other
distros.

I hope this may help others seeing this problem too.
Or has somebody an other suggestion/solution?

Cheers,

    Urs



# cat /etc/bash.bashrc.local
#
# source /etc/profile.d/*.sh again, if we run a NX session
#

if test -n "$NXSESSIONID" ; then
   if test -d /etc/profile.d ; then
      for s in /etc/profile.d/*.sh ; do
          test -r $s -a ! -k $s && . $s
      done
   unset s
   fi
fi

# cat /etc/csh.cshrc.local
#
# source /etc/profile.d/*.csh again, if we run a NX session
#

if ( ${?NXSESSIONID} ) then
   if ( -d /etc/profile.d ) then
      foreach _s ( /etc/profile.d/*.csh )
           if ( -r $_s ) then
               source $_s
           endif
      end
  endif
endif
