[X2Go-Dev] Upcoming Debian 11 freeze

2021-01-25 Thread Mike Gabriel


Hi Mihai, Stefan, Alex, Uli, etc.

the Debian 11 freeze is ahead (last uploads of new upstream releases  
are possible on Feb 6th/7th). I'd like to see some of the X2Go  
components released before that date (esp. the x2gothinclient,  
x2goclient, x2goserver and also nx-libs (already discussed with Uli)).


@Mihai: is that a feasible thing to do???

Greets,
Mike

Re: [X2Go-Dev] upgrade to Fedora 33 breaks X2Go again, no free display number available, cannot start new session

2021-01-25 Thread Ulrich Sibiller

Well, here's the code producing that output:

typeset -i retry='0'
typeset -i max_retry='10'
typeset output=''
for ((retry = 0; retry < max_retry; ++retry)); do
typeset -i free_port="${X2GO_PORT}"
if free_port="$("${X2GO_LIB_PATH}/x2gogetfreeport"
"${current_host_name}" "${ss}" 'display' "${X2GO_PORT}")"; then
X2GO_PORT="${free_port}"

if [[ -n "${SHADREQ_USER}" ]]; then

SESSION_NAME="${SHADREQ_USER}-${X2GO_PORT}-$(date '+%s')"
else
SESSION_NAME="${USER}-${X2GO_PORT}-$(date '+%s')"
fi
if [[ -n "${COLORDEPTH}" ]]; then

SESSION_NAME="${SESSION_NAME}_st${SESSION_TYPE}${X2GO_CMD}_dp${COLORDEPTH}"
SESSION_NAME="${SESSION_NAME//:/PP}"
fi

# sanitize session name
SESSION_NAME="$(perl -pe 's/[^a-zA-Z0-9\.\_\-\@]//g'
<<< "${SESSION_NAME}")"

if [[ -n "${SHADREQ_USER}" ]]; then
"${X2GO_LIB_PATH}/x2gosyslog" "${0}" 'debug'
"initializing new shadow session with ID ${SESSION_NAME}"

output="$("${X2GO_LIB_PATH}/x2goinsertshadowsession" "${X2GO_PORT}"
"${current_host_name}" "${SESSION_NAME}" "${SHADREQ_USER}")"
else
"${X2GO_LIB_PATH}/x2gosyslog" "${0}" 'debug'
"initializing new session with ID ${SESSION_NAME}"
output="$("${X2GO_LIB_PATH}/x2goinsertsession"
"${X2GO_PORT}" "${current_host_name}" "${SESSION_NAME}")"
fi

if [[ "${output}" = 'inserted' ]]; then
break
else
"${X2GO_LIB_PATH}/x2gosyslog" "${0}" 'warning'
"unable to insert display port into database. Retrying (run $((retry +
1)))."
fi
else
"${X2GO_LIB_PATH}/x2gosyslog" "${0}" 'warning' "no
free display number available, cannot start new session. Retrying (run
$((retry + 1)))."
fi
done

if [[ "${output}" != 'inserted' ]]; then
typeset msg="Unable to find free display port or insert new
session into database; parameters: port (${X2GO_PORT}), hostname
(${current_host_name}) and session name (${SESSION_NAME})."
"${X2GO_LIB_PATH}/x2gosyslog" "${0}" 'err' "${msg}"

# Make x2goclient fail.
echo "${msg}" >&2
exit '10'
fi


This boils down to

for ((retry = 0; retry < max_retry; ++retry)); do
typeset -i free_port="${X2GO_PORT}"
if free_port="$("${X2GO_LIB_PATH}/x2gogetfreeport"
"${current_host_name}" "${ss}" 'display' "${X2GO_PORT}")"; then
...
   else
"${X2GO_LIB_PATH}/x2gosyslog" "${0}" 'warning' "no
free display number available, cannot start new session. Retrying (run
$((retry + 1)))."
fi
done

-> as you can see x2gofreeport does not seem to report the port as
free. You can try this manually:

/usr/lib/x2go/x2gogetfreeport $(hostname) "$(which ss)" display 50

If that will output a free port x2go should generally work. If not,
you still have something running and blocking these ports. You can
check with lsof -i :6050 and you will see who is blocking the first
checked port.

You can also run the x2gogefreeport with bash -x:
bash -x /usr/lib/x2go/x2gogetfreeport $(hostname) "$(which ss)" display 50

and see what going on.

Hope that helps,

Uli

How does one start X2Go Windows with debug enabled? I only found for Mac
you can add the --debug flag.

My colleague also had this error:

As others already mentioned, you'll have to look up what's in 
profile.d/timeout.sh and what package that file belongs to.

Generally speaking, I'm not sure it's a brilliant idea to globally set an 
environment variable with a generic name, yet no generic semantics, in profile.

Re: [X2Go-Dev] Problem with TMOUT variable

2021-01-25 Thread Max V

Hi,
to get automatically lougut I tried with the TMOUT variable.
I put these lines in /etc/profile

TMOUT=1200
readonly TMOUT
export TMOUT

On local machine it give just a readonly error and the desktop starts.
On the contrary the X2GO session doesn't start even with only TMOUT=1200
I need to automatically logout users after a day of idle, what do you
suggest?

Max
