Bash scriipt calling Konsole in Sudo Mode

All,

I'm running Kubuntu, so it is "Konsole", not "Terminal" on my box. I need a bash script that does the following:

Kills any current Konsole sessions,
Guessing it is the cmd: myvar < ps -A | grep konsole && kill $myvar
Re-opens Konsole with 3 session tabs,
Logs each tab session into sudo mode for root

I need to register this in the Login Registry so I always have these 3
Konsole sessions open at the start of any login on my computer.

It's such a pain to have to manually do this every time I login.

Ideally, for security, the command will be:

Code:

bash /...path.../sudologin.sh mypass

which will also allow it's call at anytime and be used by any linux user and also allow, with the right symlink or rc registry, it to be called without the path name. Non KDE users will use "terminal" not konsole.

All help appreciated!

Cheers!

sounds like a lot to figure out, your side panel says you've been using Linux for at least 3 yrs now, what have you figured out so far, other then the steps of operation?

using a Konsole, or you can install a different terminal to work in so it does not kill that one while you're working on figuring out how to kill a current Konsole terminal. work out the steps in a cli then add to a script test, fix, repeat until you get it. one step at a time.

somethink like this to kill kill kill the terminals

Code:

ps ux | grep xfce4-terminal | xargs kill

xfce4-terminal --tab -T one 

xfce4-terminal --tab -T two

xfce4-terminal --tab -T three

got a look up how your terminal you're going to use is used to do these things.

teckk,

From what you are saying my script needs to say:

Code:

curdir='$pwd;

cd /Scripts/Extras/

pkill konsole;

konsole --tabs-from-file ktabs.txt

But I have not found what to put into the ktabs.txt file to:

Open the konsole with the tab bar at the top,
open each tab with execution of: sudo su -u root -p mypass. I understand I need a line for every tab I open,

I'm still researching this but no progress so far!

Cheers!

All,

On the Redhat and Suse flavors of Linux the cli cmd:

Code:

kdesu konsole

works but on the debian and Ubuntu flavors the cli cmd:

Code:

konsole -e "su -"

is the working cmd for opening a new konsole session.

Since I'm attempting the opening of multiple tabs, needing the ktabs.txt file, not sure where to put this command set, in the ktabs.txt file or before it?

Cheers!

It seems that other terminals are better than konsole nowadays. But with konsole,

Code:

#!/bin/sh



pkill -x konsole

konsole -e su - & pid=$!

konsole --new-tab -e sudo -i exec /bin/bash

konsole --new-tab -e sudo -i exec /bin/bash

konsole --new-tab -e sudo -i exec /bin/bash



echo $pid



exit 0

Code

All,

The code I currently have is Bash Script:

Code:

#! /bin/bash

# Script to login to SUDO mode

# CMD: bash /Scripts/Extras/sudologin.sh



# Get the current dir to enable return to it

curdir=$pwd;

cd "/Scripts/Extras/";

# kill the current konsole sessions

pkill konsole;

# Restart konsole in sudo mode with tabs from the file

konsole -e "su -" --tabs-from-file ktabs.txt

# Return to the starting dir

cd $curdir;

and the "ktabs.txt file of:

Code:

#! ktabs.txt file



title: Konsole%n;; workdir: /home/files;; profile: Shell

title: Konsole%n;; workdir: /home/files/Dropbox;; profile: Shell

title: Konsole%n;; workdir: /Scripts; profile: Shell

The problem here is when executed from Konsole the kill terminates the commands, so unless it is somehow stored in memory the remaining "restart" does not execute. I'm
adding this to a custom application launcher to get around this, but if you know the way to store this command set for continued execution it would be nice.

Out of curiosity I'm wondering if the "nohup" background run cmd will work?

Cheers!

The -e option should be the last item on the line.

TBotNik

01-23-2020 01:44 PM

I ran my code, both from a launcher and from an "F2" window piping to error file and got no errors, but also the 3 knosole sessions did not apprear, so there is something wrong with the code.

All,

OK found the issue with the 3rd tab in the ktabs.txt file but now wondering if the sudo cmd needs to be in that file at the end of each tab line, since none of the sessions are coming up "SUDO"?

Here is an example:

Code:

#!/bin/sh



t=$(tempfile ktabs.XXXXX) || exit 1



cat <<EOT > ${t}

title: %n;; workdir: /tmp/;; profile: default;; command=/usr/bin/sudo -i /bin/sh

EOT



pkill -x konsole



konsole --tabs-from-file ${t}



sleep 1



rm -f ${t}



exit 0

If there is still difficulty, try adding "set -xv" as the second line.

Turbocapitalist,

I see in some HOWTOs that it's -c for a cmd instead of -e to execute, but my system runs the -e. My question then is should the -e be in the ktabs.txt file. And should that replace the:

Code:

command=/usr/bin/sudo -i /bin/sh

you showed in your script as that "command=/usr/bin/sudo -i /bin/sh" is not working. Also should it be the actual cli cmd of "sudo su -u root -p mypass"? That would have the end of each tab line of:

Code:

-e sudo su -u root -p mypass

So I tried that and no change not coming up SUDO!

I'm seeing this is one of those: "Hold your mouth just right!" situations! He He!

Cheers!

01-24-2020 02:31 PM

Turbocapitalist,

Would it be that my script needs to call another script the uses a for loop to find each konsole tab and execute the "sudo su -u root -p mypass" cmd on each tab?

Cheers!

Will it work?

Turbocapitalist,

In particular I found this script:

Code:

for service in `qdbus | grep org.kde.konsole-`; do 

    for session in `qdbus $service | grep ^/Sessions/`; do

        qdbus $service $session org.kde.konsole.Session.runCommand "cd"

    done

done

Ran qdbus and got:

Code:

:1.10

 org.freedesktop.Notifications

:1.13

:1.2

 org.kde.klauncher

:1.3

 org.kde.kded

:1.6

 org.kde.knotify

:1.8

:1.9

 org.gtk.vfs.Daemon

org.freedesktop.DBus

Tried it with the grep filter
"qdbus | grep org.kde.konsole"
Got nothing and cmd:
qdbus | grep org
Gave:

Code:

org.freedesktop.Notifications

org.kde.klauncher

org.kde.kded

org.kde.knotify

org.gtk.vfs.Daemon

org.freedesktop.DBus

And cmd:
"qdbus | grep konsole"
Opened a new terminal window in sudo mode, but not a new tab.

Cheers!

Sorry! No other words to describe it, it or none of the suggestions have worked! This does not produce errors, but wondering is there is a system log that might show at least something, so I know why it's not working.

What happens when you use the example in #12 above, but add in the following as the second line of the script?

Code:

set -e -v -x

It should show each line of the script before it is executing, including variable contents, but quit on the first error it encounters.

Turbocapitalist,

Your script creates the 4 konsole sessions you described but nonoe are SDUO mode which will show with the /root in the dir prompt.

I captured your script and changed it for the 3 I was defining and here's it's code:

Code:

#! /bin/bash

# Script to open 3 Konsole sessions logged into SUDO mode

#

# CMD: bash /Scripts/Extras/kslog.sh

#

# Must be run in the SYDO mode! Also must be run from the App Launcher!



# Get the current dir to enable return to it

curdir=$pwd;

cd "/Scripts/Extras/";





t=$(tempfile ktabs.XXXXX) || exit 1



cat <<EOT > ${t}

title: Konsole%n;; workdir: /home/files;; profile: default;; command=/usr/bin/sudo -i /bin/sh

title: Konsole%n;; workdir: /home/files/Dropbox;; profile: default;; command=/usr/bin/sudo -i /bin/sh

title: Konsole%n;; workdir: /Scripts; profile: default;; command=/usr/bin/sudo -i /bin/sh

EOT



pkill -x konsole

konsole --tabs-from-file ${t}

sleep 1

rm -f ${t}

cd $curdir;

exit 0

Where do I insert your currently suggested line?

Cheers!

TBNK

Turbocapitalist

03-10-2020 12:03 PM

Insert it as the second line below the shebang. If you run the script manually from the shell, the added line will display each line of the script before it executes.

Then, as for sudo, take a look at each tab's invocation in there. In the script in the preceding post (#23) that would be lines 16 through 18 and you will see that sudo really is invoked. It is not invoked for the whole konsole program, that would be stupid as it is a graphical program. Instead sudo is invoked separately for each tab.

3 Tries

All,

OK I've written 3 scripts to try this and none of them work"

Script#1

Code:

#! /bin/bash

# Script to login to SUDO mode on all open tabs

# CMD: bash /Scripts/Extras/logsudo.sh



# Get the current dir to enable return to it

curdir=$pwd;

cd "/Scripts/Extras/";



konsole --tabs-from-file ktabs.txt -e "su -u root -p nomened.1497"

# Return to the starting dir

cd $curdir;

Script#2

Code:

#! /bin/bash

# Script to login all tabs in SUDO mode

# CMD: bash /Scripts/Extras/sudologin.sh



# Get the current dir to enable return to it

curdir=$pwd;

cd "/Scripts/Extras/";

# kill the current konsole sessions

pkill konsole;



konsole --tabs-from-file ktabs.txt -e command=/usr/bin/sudo su -u root -p nomened.1497

set -xv;



# konsole --tabs-from-file ktabs.sh

# Return to the starting dir

cd $curdir;

Script#3

Code:

#! /bin/bash

# Script to login all tabs in SUDO mode

# CMD: bash /Scripts/Extras/tmpslogin.sh





t=$("

title: Konsole1;; workdir: /home/files/;; profile: default;; command=/usr/bin/sudo -i /bin/sh

title: Konsole2;; workdir: /home/files/Dropbox/;; profile: default;; command=/usr/bin/sudo -i /bin/sh

title: Konsole3;; workdir: /Scripts/;; profile: default;; command=/usr/bin/sudo -i /bin/sh

")



pkill konsole



konsole --tabs-from-file ${t}

set -xv

sleep 1



exit 0



# title: %n;; workdir: /tmp/;; profile: default;; command=/usr/bin/sudo -i /bin/sh

I also tried putting the "set -xv" right after the pkill konsole cmd line, but that does not work either. There are no errors produce, so no idea what is wrong.

Cheers!

In your post above, script #3 is the closest to working. Export the contents of ${t} into a file and then point the --tabs-from-file at that file. Note the use of a temporary file there in post #12 above. The --tabs-from-file only works with an actual file.

sleep 1



# Return to the starting dir

cd $curdir;

exit 0



# title: %n;; workdir: /tmp/;; profile: default;; command=/usr/bin/sudo -i /bin/sh

and file ktabs.txt contains:

title: Konsole2;; workdir: /home/files/Dropbox/;; profile: default;; command=/usr/bin/sudo su -u root -p mypass

title: Konsole3;; workdir: /Scripts/;; profile: default;; command=/usr/bin/sudo su -u root -p mypass

but the only action is the actual opening of konsole with the correct title and working dir, but not sudo mode.

I'm thinking something needs to be added to the ktabs.txt file to make it go sudo! Am I right? do I need to add the "set -exv" line after each konsole def line in that file?

Cheers!

TBNK

TBotNik

04-02-2020 12:13 AM

Well,

Modified ktabs.txt to:

Code:

title: Konsole1;; workdir: /home/files/;; profile: default;; command=/usr/bin/sudo su -u root -p mypass

set -exv

title: Konsole2;; workdir: /home/files/Dropbox/;; profile: default;; command=/usr/bin/sudo su -u root -p mypass

set -exv

title: Konsole3;; workdir: /Scripts/;; profile: default;; command=/usr/bin/sudo su -u root -p mypass

set -exv

No change in operation. Still opens the 3 konsole sessions in the normal, not sudo mode!

Turbocapitalist,

I've told you at least 3 times the solution in #12 does not work!

To make sure here is the script directly from your code:

Code:

#!/bin/sh

# Script to login all tabs in SUDO mode

# CMD: bash /Scripts/Extras/newslogin.sh



curdir=$pwd;

cd "/Scripts/Extras/";



t=$(tempfile ktabs.XXXXX) || exit 1



cat <<EOT > ${t}

title: Konsole1;; workdir: /home/files/;; profile: default;; command=/usr/bin/sudo -i /bin/sh

title: Konsole2;; workdir: /home/files/Dropbox/;; profile: default;; command=/usr/bin/sudo -i /bin/sh

title: Konsole3;; workdir: /Scripts/;; profile: default;; command=/usr/bin/sudo -i /bin/sh

EOT



pkill -x konsole

set -exv

konsole --tabs-from-file ${t}



sleep 1



rm -f ${t}

# Return to the starting dir

cd $curdir;



exit 0

Then modified it to:

Code:

#!/bin/sh

# Script to login all tabs in SUDO mode

# CMD: bash /Scripts/Extras/newslogin.sh



curdir=$pwd;

cd "/Scripts/Extras/";



t="ktabs.txt";

# t=$(tempfile ktabs.XXXXX) || exit 1



# cat <<EOT > ${t}

# title: Konsole1;; workdir: /home/files/;; profile: default;; command=/usr/bin/sudo -i /bin/sh

# tile: Konsole2;; workdir: /home/files/Dropbox/;; profile: default;; command=/usr/bin/sudo -i /bin/sh

# title: Konsole3;; workdir: /Scripts/;; profile: default;; command=/usr/bin/sudo -i /bin/sh

# EOT



pkill -x konsole

set -exv

konsole --tabs-from-file ${t}



sleep 1



#rm -f ${t}

# Return to the starting dir

cd $curdir;



exit 0

Even change3d the "ktabs.txt" to:

Code:

title: Konsole1;; workdir: /home/files/;; profile: default;; command=/usr/bin/sudo -i /bin/sh

title: Konsole2;; workdir: /home/files/Dropbox/;; profile: default;; command=/usr/bin/sudo -i /bin/sh

title: Konsole3;; workdir: /Scripts/;; profile: default;; command=/usr/bin/sudo -i /bin/sh



# title: Konsole1;; workdir: /home/files/;; profile: default;; command=/usr/bin/sudo su -u root -p nomened.1497

# set -exv

# title: Konsole2;; workdir: /home/files/Dropbox/;; profile: default;; command=/usr/bin/sudo su -u root -p nomened.1497

# set -exv

# title: Konsole3;; workdir: /Scripts/;; profile: default;; command=/usr/bin/sudo su -u root -p nomened.1497

# set -exv

Added only the directory control and the "set -exv" you recommended.

None of that works except to the point of opening the 3 konsole sessions in the "normal" mode, but not "sudo" mode.

I suspected that the "sudo su" cmd was not where you think it is so entered cmd:

Code:

cd /usr/bin/sudo

And got the msg: "cd: /usr/bin/sudo: Not a directory", but it is in the /usr/bin dir. However the cmd: "command=/usr/bin/sudo -i /bin/sh" is not properly executing so something different is needed that is why I had tried:"command=/usr/bin/sudo su -u root -p mypass"! That changed nothing so I ran that cmd directly and got the error: "sudo: unable to resolve host (none)".

That cmd has to work directly from the cmdline, so need to be able to fix that and then I think it will work!

Cheers!

TBNK

PS
Oh! Running the cmd: "/usr/bin/sudo -i /bin/sh" @ the cmdline yields:

##########################################################
sudo: unable to resolve host (none)
#
##########################################################

with the "#" prompt and not knowing what to enter, only "crtl+D" exits at that point. Entering the password does not actually allow entrance into the sudo mode.

man sudo show that -l not -i is a legit option for the sudo cmd; but does not produce anything usable either.

That means the error is with the configuration of sudo and not with konsole. Re-check your settings in /etc/sudoers and make sure you can run the above command manually before retrying with the terminal emulator.

You are looking for an error there. :/ Take a look at the output using the -l option.

Code:

sudo -l

It should list what you have available for that host. If that does not give a clue then look at /etc/sudoers itself.

Code:

sudo more /etc/sudoers

And pay attention to the parts you yourself have changed. Most distros seem not to be setup for resolving the host names properly, so you may have to have it ignore the host name. There are not too many use-cases for small-office-home-office situations where it would be useful anyway.

TBotNik

04-27-2020 10:13 PM

Turbocapitalist,

I never modify this file, so don't understand why it should error. Is the error msg saying my hostname is missing or invalid? I typed in the cmd: "hostname" and the return was "(none)". But I checked the /etc/hosts file and the hostname is set to "Aspire-LT" at 127.0.1.1

Doesn't the /etc/sudoers file read this /etc/hosts file?

Cheers!

TBNK

Turbocapitalist

04-28-2020 12:23 AM

No, I don't think it does read /etc/hosts. I am somewhat sure that sudo uses the same source as the hostname utility does.

I would recommend starting a new thread about the sudo problem and then returning to this thread when that is resolved. People more familiar with sudo will see the new thread even if they have ignored this one about konsole.
