I am not able to load the logo. Everything else works tough.
What path is supposed to be in:
background-image: url('app/ext/tempnamespace/images/logo-placeholder.png');

What else can I write instead of "app/ext/tempnamespace"?
are "app", "ext" and "tempnamespace" variables or specific paths?

Running Guacamole 1.3.0 and tomcat9 on Debian 10

For those looking how to brand and theme Guacmole, I've incorporated the favicon settings mentioned in another thread with an additional dark mode template option here:
https://github.com/itiligent/Guacamole-Install

Just follow the dark-theme readme for instructions on generating and testing your own custom Guacamole theme.

Extension works fine for me in Firefox , Opera etc. But MS IE 11 display wrong logo picture.
Solution is to add tags:
background-repeat: no-repeat; background-size: cover;"
into the first section of login-override.css.
Like this:
.login-ui .login-dialog .logo { background-image: url('app/ext/tempnamespace/images/logo-placeholder.png'); width: 9em; -webkit-background-size: 9em auto; background-repeat: no-repeat; background-size: cover; } div.login-ui { background: #666; background-color: #666; } .login-ui .login-dialog { background-color: white; }

Hello,
Just trying to install custom login extension to an updated centos7.7.1908 and guacamole 1.1.0 in
/var/lib/guacamole/extensions/branding.jar
then
semanage fcontext -a -t tomcat_exec_t "/var/lib/guacamole/extensions/branding.jar"
restorecon -v "/var/lib/guacamole/extensions/branding.jar"
and restart guacd and/or reboot

and still the original Template (with cache clear and test severals browsers)

is your extension still okay with 1.1 or I'am missing on step to install ?

UPDATE

Figured it out myself actually. With the following css I was able to change every aspect (that i wanted) of the login page. Feel free to use it, just change the locations and names to yours.

.login-ui .login-dialog .logo {
background-image: url('app/ext/tempnamespace/images/XXXX.png');
width: 9em;
-webkit-background-size: 9em auto;
}
div.login-ui {
background: url('app/ext/tempnamespace/images/XXXX.png');
background-color: #000;
}
.login-ui .login-dialog {
background-color: transparent;
}
.login-ui .login-dialog .version .version-number {
display: none;
}
.login-ui .login-dialog .login.action_login {
background-color: transparent;
}
.login-ui .login-dialog .login-fields input {
display: block;

color: white;
opacity: 0.8;
}

Thanks for this! Makes it easy enough to customize my guac setup. One question or request if you will. Is there a way to make the "login" button easily changeable as well?

Can this be used to add a second login button i.e. "Login with SSO"?

Instead of having the link in the bottom left when utilising the SAML SSO extension.

Good night friend, I wanted to know the following, I downloaded the branding.jar file, edited the login image and downloaded the en.json file and put it like this:

{
"NAME" : "English",

"APP":{

"NAME" : "MultiTI" 
  }

}

However after restarting tomcat. instead of appearing the name MultiTI, only APP.NAME appears both in the title and below the logo.
I even created a pt.json and pt_BR.json file with the following content:

{
"NAME" : "Português",

"APP":{

"NAME" : "MultiTI" 
  }

}

However after restarting tomcat. instead of appearing the name MultiTI, only APP.NAME appears both in the title and below the logo.
I even created a pt.json and pt_BR.json file with the following content:

And yet AppAPP.NAME appears on the login screen, even when I remove branding.jar. Would you know what could be the problem?

PS: I'm from Brazil, so the language of my users' browsers is Brazilian Portuguese.

Hello,

What about an option to change the favicon?

Thank you!

Morning Zer0CoolX, first of all thanks for packaging this deployment has worked like a charm to get it up and running. We have grown our install, and wanted to attach a couple servers to a remote SQL server. However, when I run the script and choose not to install MySQL, it fails to restart the service as it is not found. Any recommendations to what I might need to change to overcome this issue?

Hello,
the customize extension works great, but one question is left: how to use small letters instead of capitals? The text provided seems to get completely converted. Any hints?

I tried to run and edit the branding.jar... Still i'm unable to customize it.
Any steps or thing that i can check where i missed out?

Between i already cleared all cache still the same.

Hello,

I tried to install this extension in ubuntu 18.04 and after execute this command:

$ semanage fcontext -a -t tomcat_exec_t "/etc/guacamole/extensions/branding.jar"
Traceback (most recent call last):
File "/usr/sbin/semanage", line 28, in

return ({
File "/usr/lib/python3/dist-packages/setools/typeattrquery.py", line 65, in results
for attr in self.policy.typeattributes():
AttributeError: 'NoneType' object has no attribute 'typeattributes'

Even restarted guacad and tomcat9, I cannot get the jar I edited.

I tried to coping it to /etc/guacamole/extensions/branding.jar end disable SElinux with no success.

Any idea?

Thanks a lot.

UTILITY FUNCTIONS

######################################################################

PROGRESS SPINNER FUNCTION

Used to show a process is making progress/running

spinner () {
pid=$!
#Store the background process id in a temp file to use in err_handler
echo $(jobs -p) > "${VAR_FILE}"

spin[0]="-"
spin[1]="\"
spin[2]="|"
spin[3]="/"

Loop while the process is still running

while kill -0 $pid 2>/dev/null
do
for i in "${spin[@]}"
do
if kill -0 $pid 2>/dev/null; then #Check that the process is running to prevent a full 4 character cycle on error
# Display the spinner in 1/4 states
echo -ne "\b\b\b${Bold}[${Green}$i${Reset}${Bold}]" >&3
sleep .5 # time between each state
else #process has ended, stop next loop from finishing iteration
break
fi
done
done

Check if background process failed once complete

if wait $pid; then # Exit 0
echo -ne "\b\b\b${Bold}[${Green}-done-${Reset}${Bold}]" >&3
else # Any other exit
false
fi

#Set background process id value to -1 representing no background process running to err_handler
echo "-1" > "${VAR_FILE}"

tput sgr0 >&3
}

SPECIAL ECHO FUNCTION

This allows echo to log and stdout (now fd3) while sending all else to log by default via exec

s_echo () {

Use first arg $1 to determine if echo skips a line (yes/no)

Second arg $2 is the message

case $1 in
# No preceeding blank line
[Nn])
echo -ne "\n${2}" | tee -a /dev/fd/3
echo # add new line after in log only
;;
# Preceeding blank line
[Yy]|*)
echo -ne "\n\n${2}" | tee -a /dev/fd/3
echo # add new line after in log only
;;
esac
}

Used to force all stdout and stderr to the log file

s_echo function will be used when echo needs to be displayed and logged

exec &> "${logfile}"

ERROR HANDLER FUNCTION

Called by trap to display/log error info and exit script

err_handler () {
EXITCODE=$?

#Read values from temp file used to store cross process values
F_BG=$(sed -n 1p "${VAR_FILE}")

Check if the temp variable file is greater than 1 line of text

if [ $(wc -l < "${VAR_FILE}") -gt 1 ]; then
# If so, set variable according to value of the 2nd line in the file.
H_ERR=$(sed -n 2p "${VAR_FILE}")
else # Otherwise, set to false, error was not triggered previously
H_ERR=false
fi

#Check this is the first time the err_handler has triggered
if [ $H_ERR = false ]; then
#Check if error occured with a background process running
if [ $F_BG -gt 0 ]; then
echo -ne "\b\b\b${Bold}[${Red}-FAILED-${Reset}${Bold}]" >&3
fi

FAILED_COMMAND=$(eval echo "$BASH_COMMAND") # Used to expand the variables in the command returned by BASH_COMMAND
s_echo "y" "${Reset}${Red}%%% ${Reset}${Bold}ERROR (Script Failed) | Line${Reset} ${BASH_LINENO[0]} ${Bold}| Command:${Reset} ${FAILED_COMMAND} ${Bold}| Exit code:${Reset} ${EXITCODE} ${Red}%%%${Reset}\n\n"

#Flag as trap having been run already skipping double error messages
echo "true" >> "${VAR_FILE}"

fi

Log cleanup to remove escape sequences caused by tput for formatting text

sed -i 's/\x1b[[0-9;]*m|\x1b[(]B\x1b[m//g' ${logfile}

tput sgr0 >&3
exit $EXITCODE
}

CHECK INSTALLED PACKAGE FUNCTION

Query rpm for package without triggering trap when not found

chk_installed () {
if rpm -q "$@"; then
RETVAL=$?
else
RETVAL=$?
fi
}

CHECK REPO ENABLED FUNCTION

Query repos files to view if repo is enabled trigger trap when not enabled

chk_repo_enabled () {
if grep -q "$@"; then
RETVAL=$?
else
RETVAL=$?
fi
}

ERROR TRAP

Trap to call error function to display and log error details

trap err_handler ERR SIGINT SIGQUIT

INSTALLATION EXECUTION

Runs the install if the option was selected from the summary menu

if [ ${RUN_INSTALL} = true ]; then
tput sgr0 >&3
clear >&3
reposinstall
if [ $DEL_TMP_VAR = true ]; then
rm "$VAR_FILE"
fi
exit 0
fi
`

You can see parts where i added fwe things to allow running into AlmaLinux 8
Hope it helps
