[Message part 1 (text/plain, inline)]

Package: x2goserver Version: 4.1.0.3 Tags: patch X2Go's Xsession file always starts the user's session with /bin/bash (at least on RedHat systems where SHELL is set to /bin/bash via ~/.bashrc calling /etc/bashrc). This patch attempts to determine the user's login shell and use that for launching the session. See also: https://bugzilla.redhat.com/show_bug.cgi?id=1794660 Another option might be the judicious use of the --norc option when launching x2goruncommand on followers but I'm not sure what other effects this will have or where to do that. Effects might not be to bad because I can simulate this by moving away the user's .bash_profile and .bashrc files and then the tcsh is used as expected in this case. However, while $SHELL does not get set in this case, the xfce4-session script still gets launched with bash which triggers some other errors, so this patch may be the best option. --- x2goserver-xsession/etc/Xsession | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/x2goserver-xsession/etc/Xsession b/x2goserver-xsession/etc/Xsession index 270a0b3..522f37e 100755 --- a/x2goserver-xsession/etc/Xsession +++ b/x2goserver-xsession/etc/Xsession @@ -117,6 +117,10 @@ if ! echo "*" >>"$WRITE_TEST"; then fi rm -f "$WRITE_TEST" +# Determine the users login shell and use that to launch the session +SHELL=$(getent passwd $LOGNAME | cut -d: -f7) +# Fallback +[ -z "$SHELL" ] && SHELL=/bin/bash if [ -f /etc/debian_version ] || [ -f /etc/devuan_version ]; then -- 1.8.3.1 -- Orion Poplawski Manager of NWRA Technical Systems 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion@nwra.com Boulder, CO 80301 https://www.nwra.com/
