You need to additionally grant the users (or the relevant group) access to
the sharing profile, not just the connection. Only users with access to a
particular sharing profile will be able to share the relevant connection
using that profile.

Hi Nick!

Thanks for the information;

To confirm, auto-create-users is working perfectly.

I've just tried to run the DB query to set a user as an admin however, I keep 
getting the following error;

guacamole_db=# INSERT INTO guacamole_system_permission(permission,entity_id) 
VALUES(ADMINISTER,2);
ERROR:  column "administer" does not exist
LINE 1: ...le_system_permission(permission,entity_id) VALUES(ADMINISTER...


Possible I typo'd the query:

INSERT INTO guacamole_system_permission(permission,entity_id) VALUES 
('ADMINISTER',2);

Might be that the ADMINISTER enum needs the single-quotes around it, like a 
string value. I rarely do any work directly in the DB, so I was just taking a 
guess at it.

I confirmed using TABLE guacamole_system_permission; that ADMINISTER does 
exist, so I'm not sure what is missing.

The reason for doing it this way is if I remove the OIDC authentication 
mechanism I get no login prompt so I'm trying to set the administrator role 
directly in the DB so I can do the rest.


Yep, makes sense.

Understanding Sharing Profile for Non-Admins

[Khoe, Yonathan]

Hello,
We set up sharing profiles for all of our connections under an admin account.  
We want the ability for our students to be able to generate a share link to 
their connection viewing (to their professor) when they are remoted to a 
machine.  We thought that this was the idea when we create the sharing profiles 
individually and giving them a read-only option and name, but it turns out that 
our students cannot see the "Share" button when opening the Guacamole menu 
(ctrl+alt+shift).  The student accounts themselves do not have any permissions; 
the user groups that the students belong to also do not have permissions set 
(we only use it to assign the connection groups).  Are we missing something in 
terms of letting non-admins to be able to generate a share link to be given to 
other people?

Thanks in advanced.

Re: Problems with GuacamoleHTTPTunnelServlet

[Craig Sawyer]

So now we know the server side(guacd) is up and running and actually
able to receive connections.

If the client(tomcat/java/guac) can't connect, it could be the source
address is wrong(i.e. coming from a different ip than 127.0.0.1), and
running foul of some firewall rule or the client side isn't actually
opening the connection despite the log saying it is, etc.

I know in 1.4.0 the ipv6 network stuff changed, but everything you are
doing seems tied to ipv4, unless Java is weird and changing the v4 to
a v6 address with a bunch of 0's in front, which might be possible.
I'm not a java expert.  tcpdump or the other tools should let you know
if that's the case though.

You need to verify that is happening.  tcpdump, strace, or some java
debugging magic should help you figure that out.

because the possible options for the problem seem to be limited to:

  * The host OS is being mean and denying the connections for some
reason(firewall, configuration, etc)
  * The client(tomcat) is lying/confused about opening a connection.
  * The server(guacd) is unable to listen & connect.

Since we know the last one is not true anymore, that leaves the other
2 options.  I'm still guessing it's the 1st option, since nobody else
seems to be having this issue(including me) but who knows.

Good luck,
-Craig

Re: Problems with GuacamoleHTTPTunnelServlet

[Jim Rx]

Craig,

 

I verified that guacd is running (systemctl status guacd) and then issued the command telnet localhost 4822. I successfully connected.

 

root@guac:~# telnet localhost 4822

Trying ::1...

Trying 127.0.0.1...

Connected to localhost.

Escape character is ^]'.

 

I pressed enter and the connection was 'closed by foreign host'

 

So it appears that 4822 is available on the localhost.

 

Thanks,

 

Jim

You obviously won't do anything useful, since you won't speak the

No, this won't work - you'll want the path to the actual guacd binary, not
the init script. The path to the binary can be found in the init script,
but it's different from the script. May be something like
/usr/local/sbin/guacd or /usr/sbin/guacd, something like that.

Nick,

 

Sorry for the delayed reply, We had ice storms and it kept me from work.

 

So I'm not really any further.

 

I killed guacd (systemctl stop guacd), and then, as root, from the /etc/init.d directory, ran ./guacd start -L debug -f

 

I'm not getting anything on console, but checking journalctl -xe I see the same "no such tunnel" and "connection to guacd timed out" messages

 

BTW - this is on Debian 11, if that has any bearing

 

Thanks

 

Jim
