Hi Russell, Nick, Team, Could you help to solve this issue? Probably the URL
is incorrect. Thank you in advance. I added some "echo" lines to see
output: ------------------------------------------ echo -e "TOKEN:
$TOKEN" echo -e "RESPONSE: $RESPONSE" echo -e
"IDENTIFIER: $IDENTIFIER" echo -e "Client Identifier:
$CLIENT_IDENTIFIER" This is my result now: -----------------------
TOKEN: C789F89578D3D7F7956307C26FD24410DEF12D4403495A9E2FBA43E31F92557D
RESPONSE: {"message":"Unexpected internal
error","translatableMessage":{"key":"APP.TEXT_UNTRANSLATED","variables":{"MESSAGE":"Unexpected
internal
error"}},"statusCode":null,"expected":null,"type":"INTERNAL_ERROR"}
IDENTIFIER: null Client Identifier: Error creating connection. Is is
correct now? It looks like the "RESPONSE" curl URL is invalid?! The
"permission denied" disappeared, but another error appeared. --
Best regards Marcin ------------------------------------------------- Dnia

Russell, I have a .NET application that already uses bash scripts and I would
like to maintain this standard if possible. I checked provided GITHUB repo and
I see that some updates were very long ago and the Readme.md file is empty - no
documentation. Thank you for your help. -- Marcin

you're using the correct header, here for the Guacamole authentication
token - you should be passing a header called "Guacamole-Token" with
the Guacamole authorization token. Guacamole does not generally use the
"Authorization" header. CONNECTION_ID=$(echo $RESPONSE | jq -r
'.identifier') if [ "$CONNECTION_ID" != "null" ];
then URL=" localhost:8080
http://localhost:8080/guacamole/#/client/$CONNECTION_ID?token=$TOKEN "
echo "Connection ID: $CONNECTION_ID" echo "URL: $URL" else
echo "Error creating connection." fi Two issues, here: *
We've removed the ?token= parameter in recent versions in favor of a model
that prefers/uses a header, instead, so you should leave off the token= part of
this. * Your path for the connection (/client/$CONNECTION_ID) won't work -
the client identifier is not the same as the connection ID, but is, instead, a
base 64 encoding of the type of connection (connection or connection group),
the data source (pgsql, mysql, etc.), and the connection identifier. See:
