Not sure if it helps but I just ran up a bare 18.04 VM, installed MySQL 
and tried that script. I note the install has a working ssh client already.


The script gave me an error saying that libssh2-1-dev is not available 
etc, and it fails. There were other errors too but that's probably the 
most pertinent.


That suggests to me there's something in the script that's looking for a 
specific version of ssh and failing when it can't find it. I've not 
looked at the script (no expert here) but perhaps it's worth 
investigating that and modifying as needed to suit 18.04?


Cheers.

As for the version of guacd I installed Guacamole 0.9.14 using the 
MysticRyuujin install script here is a link to it. 
https://github.com/MysticRyuujin/guac-install


I've installed this successfully before without issue, but I did a new 
OS install and restored guacamole from a backup and it's had issues 
with ssh ever since. Other protocols work fine, I can RDP into my 
windows machines without issue it's only the ssh protocol that is 
having issues.

Re: SSH issue with Ubuntu 18.04


That was the MysticRyuujin install script, not the configure script.

I realise I may have confused things slightly, sorry; I would try 
compiling it manually but need to get the router configured, pfaffing 
around with adding proxies seems not to have worked as expected. I'll 
see if I can get that done ASAP and will report back.

Re: SSH issue with Ubuntu 18.04 - updated detail

2018-08-13 Thread ivanmarcus


libssl-dev is the one.

Earlier I'd discovered that the directory paths between 16.04 and 18.04 
were quite different for some installed packages. If I put in some 
symbolic links it fixed some of the 'missing' issues, but it seemed like 
a long process and I'm sure there's a better way!


Anyway libssl-dev was the final step to getting it to compile with ssl, 
but still no recognised libssh2 (despite it being in place), nor pango 
(also in place).


FWIW the install to date wasn't easy, had to go looking for some 
packages in odd places and we're still not working. I expect just adding 
the repository and installing from there would be much more 
straightforward (?) but I guess that won't sort out the issues with this 
script and Nate's lack of ssh...

Thanks Mike, it's not the way I'd normally do it - it was more of a test 
case to see why the Mystic script didn't work.


That said at least one of the required dependencies mentioned in the 
manual wouldn't install from the standard repository, and the same with 
the optional dependencies. The two that come to mind are libpng12-dev

Re: SSH issue with Ubuntu 18.04 - updated detail

2018-08-14 Thread ivanmarcus

Further to previous detail I resumed my install testing on a brand-new 
Ubuntu 18.04 server.


For me the MysticRyuujin script would not work and it failed, unable to 
locate a number of packages.


I then proceeded to build the guacamole-server per chapt 2 of the manual 
(Installing Guacamole natively)


Several required and optional packages were unavailable and I needed to 
get a .deb package elsewhere to install.


The following is the step-by-step process required (note I was building 
for ssh only:



apt-get update

apt-get install libcairo2-dev

apt-get install libjpeg-turbo8-dev

wget 
http://launchpadlibrarian.net/330752989/libossp-uuid16_1.6.2-1.5build4_amd64.deb


dpkg -i libossp-uuid16_1.6.2-1.5build4_amd64.deb

wget wget 
http://launchpadlibrarian.net/330752983/libossp-uuid-dev_1.6.2-1.5build4_amd64.deb


dpkg -i libossp-uuid-dev_1.6.2-1.5build4_amd64.deb

apt-get install libpango1.0-dev

apt-get install libgcrypt20-dev

wget http://launchpadlibrarian.net/319154355/libssh2-1_1.8.0-1_amd64.deb

dpkg -i libssh2-1_1.8.0-1_amd64.deb

wget http://launchpadlibrarian.net/319154354/libssh2-1-dev_1.8.0-1_amd64.deb

dpkg -i libssh2-1-dev_1.8.0-1_amd64.deb

apt-get install libssl-dev


From here obtain the guacamole-server source, untar and ./configure. 
This appeared to go through ok and reports that the SSH protocol is 
available. I've not gone on to compile from here.


I'm not sure if this helps Nate, but hopefully it may be of some use to 
others? If nothing else it'll be a useful record for me when I move my 
installation of Guacamole from 16.04 (probably when the 1.0 release is out).

Re: SSH issue with Ubuntu 18.04 - updated detail

No, nothing disabled. This was a clean version of server, installed in a 
VM, following which the only commands issued were to set a root pw, su, 
update, upgrade and the requisite package install for Guacamole...


Maybe I'll redo the base install just to see if there was anything amiss.

Otherwise thanks for the suggestion but as mentioned I'm not concerned 
about it and realise there are easier ways to install, it's more about 
trying to find out why this is occurring in case it happens to anyone 
else and/or there's a need to update install detail I guess (although I 
really think this problem is an outlier as I see others have installed 
Guacamole on 18.04 ok).


I did wonder if it could be something to do with the local (NZ) mirror, 
but haven't got any further than that at this stage.

Re: SSH issue with Ubuntu 18.04 - updated detail - Resolved

2018-08-16 Thread ivanmarcus


To follow on from this.

In looking to see if there was an issue with the local mirror I found 
that /etc/apt/sources.list contained just the three main repositories, 
none for Universe/Multiverse.


Adding these repositories (per 
https://help.ubuntu.com/lts/serverguide/configuration.html.en) meant 
that the requisite dependencies for Guacamole became available per 
Nick's findings.


I'm not sure why this happened - I've not used 18.04 much as all my 
servers are yet to be upgraded from 16.04, so haven't had much 
experience with any foibles it may have - but it's possibly something to 
do with the initial base install not having internet access. This is by 
design in the network I was running it within (although once installed 
and the nic configured etc it does have full access); it's not been an 
issue with previous versions of Ubuntu, however 18.04 may treat things 
differently.


If I find out anything further I'll update this post, although I expect 
for most people installing Guacamole this won't be an issue - if there's 
going to be some esoteric problem it's usually only me that has it!

Maybe I'll redo the base install just to see if there was anything amiss.

Otherwise thanks for the suggestion but as mentioned I'm not concerned 
about it and realise there are easier ways to install, it's more about 
trying to find out why this is occurring in case it happens to anyone 
else and/or there's a need to update install detail I guess (although 
I really think this problem is an outlier as I see others have 
installed Guacamole on 18.04 ok).


I did wonder if it could be something to do with the local (NZ) 
mirror, but haven't got any further than that at this stage.

Re: Lost Password

2018-09-18 Thread ivanmarcus


There has been some good direction you've got from the list.

I can't add much to that but you've not said what distribution you're 
running, nor if you've figured out the authentication mechanism etc, 
although it would seem it's likely to be using MySQL?


If this were me, assuming you've got root access to the server, and 
before going too far I'd have a look at the command history to see if 
there is any password detail there; you would also get an idea of what's 
been done to the server recently. Usually the command history is 
obtainable when logged into the cli as root simply by hitting the 'up 
arrow' key, or in some distributions via "less /root/.bash_history". If 
you're not logged in as root the command would be "sudo less 
/root/.bash_history" for the root history (it will ask for your 
password), or simply "less .bash_history" if it's the logged in user's 
history you want to check out.


If you were to look through that for a MySQL command such as 'mysql -u 
root -p x' you may discover a useful password to try, there may be 
other hints in the history list.


I expect you've also done the obvious by trying the machine that the 
previous admin normally used to access the server, to see if there were 
any saved passwords etc. Most of us won't allow that but you never know.


Apologies if this is already stuff you've done, however I thought it 
could be useful to mention if you've not had a lot to do with Linux.

Re: Guac Access Over HTTPS w/ NGINX Reverse Proxy

2018-12-02 Thread ivanmarcus


Matthew,

It's possible your edge router isn't correctly set up. Typically you'd 
want external port 443 to resolve to the internal ip number of your 
Nginx instance on port 443.


If your router is translating the external https request (eg 443) to 
internal http (eg 80) then you may get the message you have.


Wireshark or similar may also be of some use in tracing what's happening 
internally when an external request is made...

Re: Built-in reflector/repeater support in guacd daemon (Guacamole protocol)

2018-12-18 Thread ivanmarcus

Please forgive me if I have this wrong but I think the essence of 
sapphireimsuat's request was to have two 'client' machines to connect to 
Guacamole and establish a (http[s]) link between them - but without 
using RDP/VNC and the concomittant issues around that (ie. having to 
setup routes, enable remote users etc)?


I think the best analogy would be a self-hosted Teamviewer or similar - 
although that requires a software installation on each client.


As I understand it, while it would be great if it could, Guacamole is 
not the right application for this. The closest I've found is Nomachine 
(but would be pleased to hear from anyone who's experience of anything 
else that works well).

Hi Nick,

Thanks for your suggestion. My understanding on your approach is,
having two
guacacd instance between two different network and allow connection.

My query about roaming users is, assuming I have 100 end users and
they are
roaming in different locations and connecting to internet via
broadband
connection. All will have the client component and they should be
able to
connect to Guacamole server in a single port (where repeater is
running).
Connection will be initiated from roaming user-1 and reach repeater.
Technician-1 will also be connecting to repeater to make
connection with
roaming user-1.


So, maybe there's some misunderstanding, here, about how Guacamole 
works.  Guacamole is designed specifically for this type of scenario, 
and is designed to do it without any software other than a web browser 
on the client system.  The Guacamole Server (guacd) does the 
translation between the Guacamole Client and the remote desktop 
instances. Guacamole Client does not get installed on the roaming 
client machines, it gets installed on a Tomcat server that then 
translates between HTTP(S) and the Guacamole Protocol, communicating 
with guacd.  This actually works very well for the situation you 
mention, because you can set up that Guacamole Client system in a 
central location and have it facilitate the connections to the remote 
clients.


Hopefully this helps, let me know if you have any further questions.

Not currently, perhaps, but I think that's a rather good use case for 
guac. I've actually been looking into what would be necessary to 
develop the "agent" software component to establish the route and/or 
serve the remote desktop piece to a Guacamole server configured to 
accept that route. You'd then be able to connect via guac to any 
machine that runs that software.

Poubelle, this script may be of interest as a quick and easy way to 
instal 0.9.14:



https://github.com/MysticRyuujin/guac-install


As Nick has said, you will need to install VNC server on the machine you 
wish to connect to, and ensure that the relevant settings are entered 
into the Guacamole Connection setup (that it's using VNC, along with the 
IP number and port of that machine).



You will also need to set up a User with password etc, and then 
associated the Connection you've made with that User.

Bonjour!  Bienvenue a Guacamole!

(And that's about all of the French that I know :-).  If you're 
installing version 0.9.9 then you're installing a very old version of 
Guacamole.  I think there's an old package in the Debian repository, 
but it hasn't been maintained in quite a while, so you should install 
the version from the Guacamole web site:

How to use VNC ? Duty I installer VNC server  on the debian. And

You'll need to have a VNC server to connect to, so, yes, you'll need 
to install the VNC server on whatever system you're trying to connect 
to.  Once you have that set up you just need to configuring the 
connection in Guacamole.  The Guacamole Manual can be found here:

It would be nice if all of them implemented it, yes, as that's pretty

I'm not sure if it would cover your scenario exactly but I have a small

That said it would be trivial to alter it to do other things such as run

Re: Installation script

Apropos the earlier info I've passed on I should further note that the 
detail from kifarunix.com references Guaacmole 0.9.14, but the current 
version is 1.0.0.


However I believe the _process_ should be largely similar (just replace 
0.9.14 with 1.0.0) - if you had any difficulty I'd use the Guacamole 
project installation detail to assist.

It works for me if I issue the command:

This will download the file into whatever directory you are working from

If your network is blocking direct downloads from some sites you may be 
able to utilise an ftpmail server 
(https://en.wikipedia.org/wiki/FTPmail), if there are any still running 
(a quick search suggests there may be some, but I've not tried them).


Otherwise there's probably not a lot else anyone is able to do, if 
you're not able to get the requisite files.

Re: Enter Guacamole with another URL

2019-06-20 Thread ivanmarcus

There are various examples of how to do this on the internet. It's worth 
bearing in mind that it's not Guacamole per se as Tomcat that defaults 
to 8080, so most examples of how to make such changes with Tomcat should 
be relevant to you in to some degree.


That said, and as you're wanting to also use https, I'd suggest this 
looks to be a reasonably thorough step-by-step guide that should achieve 
all of what you need:


https://www.vultr.com/docs/create-an-html-5-rdp-ssh-frontend-using-guacamole-on-ubuntu-16-04-lts

I've not used the guide myself, and your components may differ from 
theirs, but I'd encourage you to look at the process - which should be 
largely the same whatever.

Re: Us keyboard not work on XRDP

2019-08-15 Thread ivanmarcus


Manoj,

There is some explanation in the link that Nick included, you will also 
see that Nick has merged the fix into the master code.


In terms of your installation, no doubt someone will correct me if I'm 
wrong but I believe that if you (re)compiled Guacamole from source this 
fix would now be included and caps lock will work. However if you've 
installed from a binary it won't assist you until the next release.


I'm not sure of your exact issue but I expect you noted this: "it only 
impacts the key up and down events for the Caps Lock key, not Caps 
Lock's effect on sending uppercase [A-Z] characters"?


I mention this because I'm presently typing this response via a 1.0.0 
binary install of Guacamole to a Win7 VM and THE CAPS LOCK key works for 
capitalising what I type. FYI while I don't specifying it I am using a 
'US keyboard'.

2019-08-18 Thread ivanmarcus


Manoj,

Unfortunately this group can't always give solutions, especially when 
there is little information. It would assist greatly if you could look 
for solutions yourself, post what you've done to resolve the issue and 
what you've found, and perhaps include log detail where useful (or when 
asked). All of this will help to narrow down what the issue might be.


Following on I've had a look to see what 'msctc' is but I'm unable to 
find out.


However per my previous respone I've found that caps lock works for me 
with Firefox v68 on Mint 19 -> Guacamole 1.0.0 -> Win7. I've just 
downloaded Chromium to test it for you and I find that caps lock works 
ok there too.


Per Nick's earlier suggestion it's possible that something at your 
client end is failing to pass on the necessary information to Guacamole. 
To help find out where the issue lays he's made a suggestion about 
trying the Guacamole on-screen keyboard, did you try that? Also, have 
you tried a completely different client? Can you get someone else to log 
in and see what happens?

Yes, you're correct - the change has been merged into the master
code, so the fix will only be available if you check out the git
master branch and compile it.

We don't distribute any binaries of the guacd code - the closest
we come is the Docker images, which are still compiled from
source, so one way or the other you'll probably be compiling
this from source until we push new Docker images.

I'm not sure of your exact issue but I expect you noted
this: "it only impacts the key up and down events for the
Caps Lock key, not Caps Lock's effect on sending uppercase
[A-Z] characters"?

I mention this because I'm presently typing this response
via a 1.0.0 binary install of Guacamole to a Win7 VM and THE
CAPS LOCK key works for capitalising what I type. FYI while
I don't specifying it I am using a 'US keyboard'.



It's also worth noting that the Caps Lock key may be intercepted
by O/S, window manager, and/or browser before it actually hits
Guacamole - this will vary platform-to-platform and
browser-to-browser - so if you're just pressing the Caps Lock
key expecting it to turn on in the RDP session, you may be
expecting something that won't work on your own platform.  One
way to begin to track this down is to enable Guacaomle's
on-screen keyboard (through the menu) and toggle Caps Lock from
that keyboard to see if it works within the RDP session.

Re: Us keyboard not work on XRDP

2019-08-19 Thread ivanmarcus


Thanks, that's useful as I wasn't aware you were using x11rdp.

I've not used it before but have just installed xrdp on another Mint 19 
machine and attempted a connect via Guacamole.


Unfortunately I get the login screen but when I enter the requisite 
detail it goes to a blank screen and I can't do anything further. Having 
had a look around it seems this isn't uncommon with xrdp on debian based 
systems but none of the fixes I've seen to date have been able to sort 
it out.


Thus I'm sorry I can't test that further right now (it''s getting late), 
however I did try the caps lock at the login prompt. What I found may be 
useful for further fault-finding(?):



Guacamole is 1.0.0 on Ubuntu server 16.04 server VM, keyboard for 
specified RDP connection is set to nothing, or US, or UK, target is xrdp 
0.9.5 on Linux Mint 19.0, client is FF 68.0.1 on Mimt 19.2:


At login the caps lock key doesn't work, shift will happily give caps

The Guacamole on-screen keyboard caps lock works fine.

If I switch back to the remote keyboard the state of the caps lock from 
the Guacamole keyboard remains (ie. all typing is in caps) and caps lock 
still doesn't do anything, however shift will return the typing to lower 
case while it's pressed.


If I set the Guacamole RDP connection to a Unicode keyboard the caps 
lock key *will* work as expected and I can select caps on / caps off 
with seemingly good results.


With the same Guacamole/Ubuntu VM and same client caps lock works fine 
to a Win7 target with nothing specified for the keyboard.


WIth the same Guacamole/Ubuntu VM and same client caps lock does NOT 
work to the Mint 19 target machine with x11VNC running on that machine 
(and appropriately set up in Guacamole - with no keyboard set).



Bear in mind I can't check within a xrdp session because I can't get 
beyond the login prompt but for the moment you might want to try 
changing your keyboard type to Unicode and test that out, then let us know.


This sort of information may be useful for those who know more about 
these things, it could give them a pointer as to what the issue is and 
if there is an easy way to address it.


At this stage, and with my single user case and limited knowledge, it 
suggests to me the issue is replicable between Guacamole and a Linux 
target, initially it doesn't seem to be client related, and may not be 
anything to do with the protocol in use (ie. VNC or RDP).

narrow down what the issue might be.

Following on I've had a look to see what 'msctc' is but I'm unable
to find out.

However per my previous respone I've found that caps lock works
for me with Firefox v68 on Mint 19 -> Guacamole 1.0.0 -> Win7.
I've just downloaded Chromium to test it for you and I find that
caps lock works ok there too.

Per Nick's earlier suggestion it's possible that something at your
client end is failing to pass on the necessary information to
Guacamole. To help find out where the issue lays he's made a
suggestion about trying the Guacamole on-screen keyboard, did you
try that? Also, have you tried a completely different client? Can
you get someone else to log in and see what happens?

2019-08-21 Thread ivanmarcus


Thanks, that's useful.

In my test case the Guacamole on-screen keyboard works, and I can get it 
working with the physical keyboard if I change the Guacamole keyboard 
type to Unicode (local keyboard type remains US).


In your case the Guacamole on-screen keyboard also works correctly, but 
setting Unicode in Guacamole doesn't fix it for the physical keyboard.


I'm not certain but, bearing in mind Nick's earlier comments, I suspect 
this means the issue may be between your local machine and Guacamole 
(ie. it's probably not the target machine).


If it was working some time ago then I would look back to what changes 
or updates you have made to your local machine, and to the Guacamole 
machine, since then. It's possible some small change or update has 
affected the keyboard operation.


As I don't use Centos, and don't seem to be able to easily get xrdp 
running on my test machine anyway, I'm not able to clone your 
installation or exactly replicate the problem, sorry. Therefore I think 
we've probably reached the limit of what I'm able to do to help.


Beyond this it will need someone with better skills than mine to assist 
further, however if I think of anything else I'll pass that on.

I've not used it before but have just installed xrdp on

Unfortunately I get the login screen but when I enter the
requisite detail it goes to a blank screen and I can't do
anything further. Having had a look around it seems this
isn't uncommon with xrdp on debian based systems but none
of the fixes I've seen to date have been able to sort it out.

Thus I'm sorry I can't test that further right now (it''s
getting late), however I did try the caps lock at the
login prompt. What I found may be useful for further
fault-finding(?):


Guacamole is 1.0.0 on Ubuntu server 16.04 server VM,
keyboard for specified RDP connection is set to nothing,
or US, or UK, target is xrdp 0.9.5 on Linux Mint 19.0,
client is FF 68.0.1 on Mimt 19.2:

At login the caps lock key doesn't work, shift will
happily give caps

The Guacamole on-screen keyboard caps lock works fine.

If I switch back to the remote keyboard the state of the
caps lock from the Guacamole keyboard remains (ie. all
typing is in caps) and caps lock still doesn't do
anything, however shift will return the typing to lower
case while it's pressed.

If I set the Guacamole RDP connection to a Unicode
keyboard the caps lock key *will* work as expected and I
can select caps on / caps off with seemingly good results.

With the same Guacamole/Ubuntu VM and same client caps
lock works fine to a Win7 target with nothing specified
for the keyboard.

You need to check your guacd logs. Only guacd is aware of anything

seeing from the web application suggests that it simply cannot

Re: Windows 10 licencing

2019-09-18 Thread ivanmarcus

I find it difficult to discuss M$ licensing and business practice
without wanting to scream but, as far as I've been able to work out
(after _many_ hours of research), if you want to run M$ Windows in a VM
and access it remotely you can do this with:

- a VDA (Virtual Desktop Access) license

- Enterprise with SA 'software assurance'

I believe both of these require an annual fee (something that's an
anathema to my clients, and me).

Trying to understand and explain this cr*p to clients is a nightmare.
Quite reasonably one asked me just a couple of days ago 'why can't I
just buy two normal licenses for the two remote machines I want to
connect to my accounting package?'. Oh my! - that's all the poor guy
wants to do, and the fact that it's _easy_ to do technically (either 2 x
VM's or use the termiserv.dll to allow multiple connects [that M$
released]) , but is complicated to to hell and gone by M$ rapaciousness
really makes me spit.

G [sound of deep breathing and counting to 1000].

Anyway, that's my read of it, but you'd really need to consult M$ to be
sure. In practice I expect many just give up and either do it anyway, or
find an alternative.

In the absence of a Linux application and with regard to the latter if
anyone has any experience of 'TSPlus'
(https://www.terminalserviceplus.com) or Graphon go-global
(https://www.graphon.com/) I'd be pleased to hear from you - I'd still
like to get this guy access to his package without having to interact
with M$ and have it cost the earth, forever, and these two application
publishing systems appear to offer a possible way forward

Hi,
I was wondering what Windows 10 licences people were using for
Guacamole? We want to have users logging in one at a time, but
have the windows 10 machine installed as a VM on a VMware Esxi
server, with Guacamole connecting to the server via RDP. We're
planning on buying retail Windows licences.

Section 2c v.) of the Windows Licence (

https://www.microsoft.com/en-us/Useterms/Retail/Windows/10/Useterms_Retail_Windows_10_English.htm
)
seems to prohibit this;
/ install the software on a server and allow users to access it
remotely, or install the software on a device for use only by
remote users; /

This seems to contradict 2d v.)
/Other users, at different times, may access the licensed device
from another device using remote access technologies, but only on
devices separately licensed to run the same or higher edition of
this software. /
/
/
But does that mean that it's only within licence terms to access
the machines from a Windows 10 Home pc?

It's been a while since I dealt directly with Windows workstation
licensing, but my recollection of the license terms are as follows:
- You can use the remote desktop feature of a Windows workstation on a
standard PC to access that system from a Windows edition of equal or
greater (e.g. Pro -> Pro, Enterprise -> Pro, etc. - 2d).
- You *cannot* run any edition of Windows lower than Enterprise on a
server to use in a "VDI"-type scenario. This means using Retail
edition for VDI-like functionality is a no-go in Microsoft licensing
terms.
- Not only do you need Enterprise Edition or higher (I think Ultimate
is higher), you also need to maintain Software Assurance on the
licenses you use for VDI.

Again, that's my recollection. I'm also not sure how much of that
guidance was "reseller guidance" (someone who's in it for the $$) and
how much of that was honest legal guidance (if you do this, you're
actually in violation of the EULA). I'd recommend you consult someone
intimately familiar with Microsoft licensing, but who's not in it to
get your money (good luck finding said person).

Re: 6 Monitors/6 miniPCs - How to set up Guacamole

2019-10-01 Thread ivanmarcus

FWIW, per David's response, I have a site that is very similar to yours 
insofar as there are several M$ machines that are accessed via a 
Guacamole instance that is itself running on a M$ machine.


I achieve this by running Guacamole in an Ubuntu VM from Virtualbox, 
this runs happily on a machine that is also in daily use for other 
tasks, and is occasionally itself accessed via Guacamole. You probably 
don't need a lot of Linux experience to get this working as there are 
various examples of how to install Virtualbox on M$, and Ubuntu (or 
whatever) as a VM under Vbox. Once you've done it a couple of times I'm 
sure you'd find it fairly easy in fact.


From there installing Guacamole is relatively straightforward; I know 
I've posted to this forum a couple of step by step command lists that 
would get it up and running in a relatively short time (maybe 15mins?).

Re: Upgrading to 1.0.0, url for login

2019-10-08 Thread ivanmarcus


FWIW I've just checked this with one of my instances.

I'm unable to replicate the issue with Guacamole 1.0.0, MySQL 5.7.27, 
Ubuntu 16.04.6, Pacific TZ.


In the past I've found weird things can happen around timezones and so I 
did try setting different TZ's in Guacamole (keeping the system TZ 
intact) but couldn't get it to operate differently.


As I recall this was a new installation of 1.0.0, if yours is an upgrade 
I wonder if there's some hangover that's causing an issue from your 
0.9.13 install?

What I do not see here, that is almost certainly required for RDP

your Win 10 system is set up to require NLA (which it is by
default), then the username and password *must* be provided at
connection time, or the connection will fail.  At this point
Guacamole does not support prompting for parameters, though that

you will need to turn off the NLA requirement for Windows 10.

Re: Windows 10 flaky RDP

2019-10-21 Thread ivanmarcus

I see Mike's post regarding which VM you're rebooting etc, so with that 
in mind it may be useful to know that I also have a similar system in 
operation and that, with one exception, it runs reasonably well (thus, 
one would hope, so should yours :-).


I utilise Vbox 6, Win10Pro in a VM, Guacamole 1.0.0 in a VM (Ubuntu 
18.04), all hosted on a Mint 19 based box. I've not tried VRDE but the 
Win10 desktop direct, or via another Win RDP connection or Guacamole, 
performs reasonably well with no connection failures.


The one issue I have is high CPU idle usage (>100%) by the Win10 VM. As 
I understand it this is not uncommon with Win10 on Vbox, but there 
doesn't appear to be a consistent fix for it at this time (annoyingly). 
This does seem to slow down the Win10 operation at times, and it (Win) 
has crashed a couple of times, but it doesn't seem to cause any 
connection problems per se. The Ubuntu VM, and the Mint box both have 
reasonable CPU utilisation.


To carry on with your specific issue -  while you don't mention if 
you're hosting Guacamole as VM, or natively, and whether it and the Win 
VM are on the same host (part of Mike's uncertainty I think), it may be 
useful to look at resource utilisation, particularly while refreshing. 
Although I don't necessarily expect it to be a the nub of your problem 
it's a simple thing to check, just in case it's maxing out and dropping 
the connection.


Other things that would be useful to check are:

(1) do you connect to anything else with your Guacamole instance and, if 
so, are there any issues with that?


(2) How does a direct Win or Linux client RDP connection to the Win10 VM 
perform (ie. not using Guacamole)?


(3) Was your Win10 VM a new install or imported from somewhere else? If 
the latter are the network adapter settings correct (this can sometimes 
cause issues with Vbox)?


(4) Is there any anti-virus software running on the Win10 VM? If so, try 
disabling that to see if for some reason it's objecting and shutting 
down the connection.


etc...

Re: AW: Windows 10 flaky RDP

2019-10-22 Thread ivanmarcus


That's interesting Joachim,

FWIW in the scenario I described earlier for my Win10 VM instance I 
block all M$ connections at the edge router, so the Win10 install cannot 
change - in which case I wouldn't notice if they broke anything.


I also do the same thing with a 60+ user instance of native Win machines 
I have connecting via Guacamole.


Having M$ automatically eff around with your systems is not ok IMV! At 
least if you apply a patch yourself and something stops working 
afterwards you've got a clue as to why, but it's much more difficult to 
fault find if it happens without you knowing.


Anyway, the upshot of this is that if what you say is correct then I 
would anticipate other people should have the same issue, whereas I may 
not. However I've not heard of any widespread problems (other than 
Peter's earlier) - is your flaky connection just to one machine or do 
you have it across multiple?

Re: Some info for a newbie

2019-12-10 Thread ivanmarcus

Hi,

Re your questions, this is my view:

(1) A separate instance per site would be the best, and what everyone
would recommend. I suppose you could use a central instance and provide
sufficient routes to each individual PC but I expect it would be much
slower from a user perspective, and less secure - altogether a bad idea.

(2) If I understand your question I'd say you could connect to as many
PC's as your browser and machine memory would allow. I regularly run
several hundred tabs in Firefox, it would make little difference whether
they were all connections to Guacamole, or any random website.

(3) I have 60+ [possible] users installed on a VM with 2Gb RAM. They do
not all work at the same time however, I think there's typically no more
than 10 concurrent users and it works fine. I think I upped it from 1Gb
RAM a while ago because I thought it was getting a bit close, but it did
work ok with that when there were less users.

(4) I'm not sure, I seem to recollect Mike or Nick may have made some
calculation/suggestion around this - perhaps you could search the
archives to see? If not I expect someone will respond.

(5) I can't speak from experience myself but I undertand there are
people that have had success with a Pi. I've tended to use a VM because,
amongst other things, it's easilyreplicable across sites and I have
spare machines there (including machines that people also work on at the
same time). That said I'd not hesitate to use a Pi, particularly a 4/4
if you anticipated a few concurrent users.

(6) A while ago I wrote a small Python script that runs with Guacamole
and sends out the necessary magic packet. In the site I have this
running on it has worked well. Once again the detail on that is in the
archives here:

for Guacamole at one stage. This may integrate with the GUI, allowing
one to set the MAC address in the connection page, although that's
purely my speculation! Nick may update us on this?

I'm new with Guacamole.
I'm already reading the manual but I need some information to get started.
I have to connect my PC to different remote PCs located in different
locations.
There are PC and server both Windows and Linux.
Obviously, each location has a different public IP and an internal PC
network behind a router/firewall.
I currently use TeamViewer (Pro License).

1) Do I need to install a Guacamole server in each location or can I install
only one "general server"?
2) From my PC, via browser can I connect to how many remote PCs?
3) How much memory do I have to provide for the Guacamole server?
4) How much memory for each connection?
5) Can I install Guacamole on a Raspberry Pi 3/4 dedicated exclusively to
this service?

Furthermore, with TeamViewer I can see which PCs are active and if necessary
turn them on via WOL. TeamViewer uses one of the other active PCs to launch
the Magic Packet.
I suppose this is no longer possible with Guacamole.
6) So, do you have any suggestions for an alternative?

Thanks in advance.

Re: Some info for a newbie

2019-12-11 Thread ivanmarcus


If I understand your use case I guess you'd need

(1) a TSR prog running on each PC behind the router/firewall

(2) have the TSR remotely interrogable

(3) have the TSR send the magic packet to whichever local machine the 
interrogation commanded


Presumably this is something Teamview does; in my infrequent 
interactions with it I seem to recall it loads a TSR if not told otherwise.


I recollect that Mike thought there was a use case for Guacamole to do 
something similar to Teamviewer. This would be excellent in my view 
(Guacamole being open, and amongst other things the Teamviewer license 
model/cost is 'difficult' for very low and/or intermittent commercial 
use), but I expect it would require a similar small TSR of some sort to 
operate. While there are other things it would need to do I guess this 
magic packet functionality could be included...


Obviously this would require some work and while I like to help sadly 
I'm no programmer - therefore it would need to wait till whenever 
someone with the necessary skills is able to do this.


In the interim, if it were me, I'd guess I'd consider assigning one 
machine in each remote as a 'server', which doesn't have WOL enabled, 
and run a small permanent [Linux] VM effectively as a TSR that would 
allow you to interrogate and command a magic packet to whichever [other] 
machine you want to turn on.


In effect this is what I do in one office with Guacamole running as a 
permanent VM on a M$ box that is also used as a standard client machine. 
This VM allows remote access to the host and other PC's in that office. 
Should the host machine be turned off Vbox just runs on start, and loads 
the Guacamole VM in the background - in your case you'd not require 
Guacamole, just a very minimal Linux install. It's a little clunky but 
it could work?

Thanks for the reply.
I am also used to installing services behind the firewall of remote offices.
But I often find myself in the need to connect offices with a few PCs, from
2 to 5, and it is not always possible to mount a dedicated PC or even a
Raspberry.
This is why I imagined a central server that would allow connections in this
way:
PC 1-1 = IP1: Port 6901
PC 1-2 = IP1: Port 6902
PC 2-1 = IP2: Port 6901
...
PC N-1 = IP "N": Port 6901

Obviously the local firewall addressed the traffic coming from the IP of the
Guacamole Server to the various PCs using the ports as a reference.

About your answer on WOL, I find it useless if the Guacamole server is
behind the firewall because I could very well take control of the server and
from there send the Magic Packet using one of the many Linux utilities.
The situation would be different if the server is centralized, but there
would always be the problem of how to send the Magic Packet to the various
networks via the Internet.

Team Viewer uses the other PCs in the network.
First I identify in the configuration the various PCs and when I want to
turn on the PC number 5, for example, TeamViewer goes to see if there is
another PC active and sends the Magic Packet from this to the number 5.
I don't know how to do it, I never investigated it.
However, this is convenient because if I have to connect to a PC that is
turned off, I don't have to make another remote connection just to turn it
on.
Maybe there's another utility in Linux

(1) A separate instance per site would be the best, and what everyone

Re: Guacamole Stopped - guacd = Unable to bind socket to any addresses.

2020-01-20 Thread ivanmarcus


Dennis,

I've had nothing to do with CentOS (so you might need to modifiy the 
paths/filenames I give below) but the detail Mike is talking about may 
be located in your syslog.


This is what I'd do in Ubuntu/Debian:

cat /var/log/syslog | grep guacd   - this will troll through the system 
log and report any line that starts with 'guacd'


At some point you may also want to look at the tomcat catalina.out file.

tail -600 /var/log/tomcat7/catalina.out | less   - would give you the 
last 600 lines of this log file, piping it to less which will allow you 
to scroll through it nicely. You can change the 600 to any number you 
like, or use 'f' which will give you a live view.


With luck the data in these log files will give you some pointers as to 
what's going on.

Install process for Apache Guacamole 1.1.0 on Ubuntu 18.04.3 server

2020-01-30 Thread ivanmarcus


Thanks for the new version of Guacamole :-)

I thought it might be useful to update the previous step-by-step install 
detail I'd done for Guacamole 1.0.0 on Ubuntu 18.04.2 server.


The following worked for me in a new VM, but note that I installed 
libpng-dev rather than libpng12-dev, seemingly with no detriment. Also I 
didn't need to create a reduced-privilege user with writable home 
directory as I understand has been required for some. That said my 
testing has been brief and limited to one RDP session only, so YMMV...

Hi David,

No particular reason, other perhaps than that I'm fairly [very] 
conservative and had no issues with Tomcat 8.


However I've just spun up a new VM and installed Guacamole+Tomcat 9, and 
am writing this via that installation now. It should have some more 
testing I suppose but at this stage it appears to be working fine.


I did nothing more than replace '8' with '9' in the list, but for

Re: FreeRDP Writable User Home Dir?

2020-02-04 Thread ivanmarcus

I can't completely answer your question but thought I'd drop in to say 
that in the several instances of Guacamole I have running I always check 
'ignore cert', IOW I consider this normal practice.


In my largest installation (~60 possible users), presently utilising 
Guacamole 1.0.0., we have a mix of Win7 and Win10 machines.  If I don't 
check the box at least one group of machines fails to connect (it's 
currently in use so I can't check for sure which group - or if it's both).


Given what I've read I suspect it occurs due to uncheckable self-signed 
certs, but I've never pursued the 'why'. As I trust the machines I set 
the specific connections up for within the internal network I don't see 
the need to go much further in terms of security checking.

The client is a Windows 7 Pro box. I found that if I checked the box for

Any idea why this would be needed? Previously, Guac 1.0.0, freerdp 1.x,

What does the error actually mean? What certificate failed verification? IS
this correctable or is the only option to ignore the cert?

I'm not familiar with the error, and I don't know what the most recent 
form of that script does in terms of installed packages, but it may be 
worth checking the version of FreeRDP you have installed is compatible 
with whatever version of Guacamole you are running?


Guacamole 1.1.0 uses FreeRDP 2, earlier versions require FreerRDP 1.

Also, if you'd like to check out this thread you'll see a cople of posts 
I made that show the steps required to install Guacamole 1.1.0 to a 
fresh Ubuntu server 18.04.2 VM:


http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/ANNOUNCE-Apache-Guacamole-1-1-0-td7127.html

I ran through that install process several times so I'm reasonably happy 
it should work 'out of the box' for RDP sessions if you followed the 
steps laid down.

Re: Error 114 in gaucd?

Ok, sorry, I've never had that error and not knowing what had transpired 
during the script install thought it may have been something to do with 
that...


However, given you've utilised the steps I posted, and I know for sure 
that works for Win10, you may simply find it's a matter of setting the 
correct parameters in Guacamole and/or the Win10 box.


Other than the requisite IP address and port etc my Guacamole is set 
only to "ignore server certificate" (and one or two other things 
regarding font smooting and colour depth). Try setting that if you 
haven't already.


Unfortunately the notes I have for my Win7/10 clients aren't to hand at 
present, so I can't be sure if there's anything else we do, but if that 
doesn't work you could try disabling NLA on the Win10 box to see if that 
sorts it out.

Ivan,

Thanks, I just spun a fresh VM and ran through your steps (starting 
with the 1:18 am posting), and everything seemed to go OK, but I still 
get the ERROR 14 connecting to my Win10 VMs.


So, probably my other setup is/was working OK, and there's something 
odd in my (Win10) configuration, but I can't think of what it might 
be.  As I say, I can RDP with the MS Mac client and Remmina (which is 
totally vanilla) from the guac VM, so I know the client can work, and 
both of my Guac vms are throwing this error.  I'm sure that should be 
telling me something, but I have no idea what it is.

Re: Required help for reducing High Bandwidth Utilization of Guacamole


In the Guacamole GUI there's a tickbox 'disable audio'

You could also check this out:

http://guacamole.apache.org/doc/gug/configuring-guacamole.html

which explains how the audio works (and from that perhaps how you might 
deal with it in your configuration).

Hello Mike,

We have investigate further and there in we found that there's
an continues ACK/SYN/PING traffic flows between server and
client for an absolutely idle session.


Yes, this is by design - the Guacamole protocol has built-in
mechanisms to verify that the connection is still active and
prevent the server (guacd) from dropping the connection.  However,
as Mike stated, the amount of traffic generates solely for keeping
alive an idle connection is very low - 17Kb/s - so it does not
account for all of the traffic you are seeing - something else is
going on.

Due to which number of packets and in turn data exchange
increases continuously for an absolutely idle session.


Absolutely idle is a little bit of a misnomer, here. If a session
is in progress, it will *never* be "absolutely idle" - that is,
there will always be some amount of minimal data exchange in order
to keep the session alive - else it will shut down.  This is true
of pretty much any protocol - RDP, VNC, SSH, Telnet, and Guacamole
- all will have some minimal amount of overhead client/server
traffic even when there are no mouse/keyboard actions and the
screen is not being updated.


Can you please guide us on how to stop continues server
PING/NOP/ACK/SYN ?


No, this cannot be disabled without changing the code, and the
result would be undesirable - the remote connection would shut
down.  And, this isn't a problem - again, the amount of data
you're seeing shows that something else is going on aside from a
completely idle connection.  You might check and see if audio is
being generated that would account for the higher bandwidth
utilization, or if file sharing is enabled.

And, as Mike said, in order to truly debug what's going on, here,
you need to look at the traffic un-encrypted.  This will allow you
to see the actual Guacamole protocol packets that are being
exchanged and figure out where the data is coming from.

Re: Error 114 in gaucd?


Here's an abridged version of what we do for the Win machines:


Use secpol, set to not display last username

Set account lockout threshold, duration and counter

Allow connections from any version of RD

Regedit:
 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal 
Server\WinStations\RDP-Tcp]

“SecurityLayer”=dword:0001

As we use WOL there's also some power management stuff to set.


Guacacmole I've previously described. FYI I don't set the sim 
connection, nor do I set authentication detail (users first log into 
Guacamole, then need to enter their Win user/pass).


This works fine, however I did have a similar issue to what you describe 
with another client (Remmina worked, Win RDP client worked fine, but 
Guacamole wouldn't) and although I no longer recollect the error number 
in the end it turned out to be some specific security policy they'd 
implemented on the Winboxen.


As I wasn't too involved in that side of it I can't be any more specific 
but the above may be enough for you to get it operational anyway?

I don't.  I really do appreciate the input.


  * MacOS RDP connects fine
  * Remmina on GuacVM connects fine


  * NLA is disabled on Win10 target
  * Guac-have checked IP and port (actual doesn't seem to care if port
is blank)
  * Guac-have checked to 'ignore cert' (it does seem to need this)
  * Guac-have set to 32b color (doesn't seem to care about this)
  * Guac-have checked pass/user (it clearly breaks with a bad pass)
  * Guac-have selected RDP protocol/location root
  * Guac-have set simultaneous connections to 10/10
  * Guac-security method, have tried blank/any/and NLA (when NLA was
turned on on Win10)
  * Guac-everything else is blank
  * Guac-log seems to connect briefly before the error 14 in guacd
  * Guac-SSH protocol connects fine


Any RDP connection ends with ERROR 14.  I think I'll try spinning up a 
Ubuntu 16 VM to see if it acts different.  Very odd and annoying.
