Frequent disconnections occurring now
Hi
All our current users are reporting frequent disconnections and slow service from Guacamole
I performed the usual maintenance recently, stop / start server, and rollover the docker images which usually clears the issue, but its not fixing this now
Any ideas of where to look?
Guac has been in service for about 3 years now. I am keen to upgrade but that's another thread.
Thanks

Hi
Thanks for your response
I’m seeing a lot of these about time that the disconnections seem to occur

Check the guacd logs.
Guac has been in service for about 3 years now. I am keen to upgrade but that’s another thread.
You really should upgrade as soon as you can. Three years is a lot of fixes to be missing out on.

This would seem to indicate either the user doing something (logging off)
or an administrative setting kicking in that is forcing the logoff (idle
session timeout, session time limit, etc.).

Hi
These seem to be from the same user with 4 sessions this morning
There seem to be various causes
That user logs in via a highly available corporate network so it should be reliable
I am curious about these two logged events
"The disconnection was initiated by an administrative tool on the server running in the user's session.”
Could the user be doing something?
Thanks

If you were indeed still connected (you didn't close the browser tab), this indicates that there was a network disruption. Something interrupted communication and resulted in Guacamole considering your connection closed and cleaning up your connection.
Other users are reporting disconnected sessions of 46 seconds and such like
You will need to locate the logs for those disconnects to determine the cause. The fact that other connections closed is not enough to determine why they closed.

These messages indicate that Guacamole is unable to connect to guacd. The most likely cause is guacd is not running.
If you are still seeing issues after starting guacd, you really need to check the guacd logs. The logs you are looking at now are the Guacamole (webapp) logs. The webapp will not be aware of the specifics of any issues guacd may be having in connecting to your remote desktops.

You really should upgrade as soon as you can. Three years is a lot of fixes to be missing out on.

There was never any such version as 0.99 - there probably was a 0.9.9, but
that is many years old. Can you confirm that this is indeed the version of
Guacamole you're running? If so, you might want to start by upgrading it.

Hi
The server is hosted in AWS, so drivers are native. Instance is T2.large if you know what that is
Internal network traffic is symmetrical line speed determined by the instance type. Internet will be the same
HM VM's does the host have? Hundreds I would guess. Hypervisor in ZEN
The instances runs 5 docker containers with proxy, database and 3 guac services
The guac version is 0.99
Hope that helps

What type of bandwidth do you have?
Upload
Download
Are you symmetrical or Asymmetrical on speeds?
Then on your internal network, are you 1000Mbps or 100Mbps.
Also does the Guacamole system have the VM drivers installed ?
What type of load does the host server have (how many VMs running at once)
What type of Hypervisor ?
Microsoft Hyper-v
Citrix Xenserver
VMware ESXi
Oracle cloud/virtual box ?
The more I know about your infrastructure the better I can assist.

The server is 2 vcpu 8GB RAM, moderate network
For the last 4 weeks, while disconnections are occurring, CPU has not got above 30%
We have about 25 users, but not more than 5 concurrent users at any time
Version is older.
Any guidance appreciated

How many users to a guacamole server?
Memory CPU play a big part.
We service over 2000 users across 5 Guacamole servers
Guacamole Specs:
* 8 vCPU
* 64G Ram
* 10G Network
Connection are stable with these specs.
Versions:

RE: Frequent disconnections occurring now
Posted by Sean Hulbert <sh...@securitycentric.net.INVALID>.
What type of bandwidth do you have?
Upload
Download
Are you symmetrical or Asymmetrical on speeds?
Then on your internal network, are you 1000Mbps or 100Mbps.
Also does the Guacamole system have the VM drivers installed ?
What type of load does the host server have (how many VMs running at once)
What type of Hypervisor ?
Microsoft Hyper-v
Citrix Xenserver
VMware ESXi
Oracle cloud/virtual box ?
The more I know about your infrastructure the better I can assist.
Thank You

The server is 2 vcpu 8GB RAM, moderate network
For the last 4 weeks, while disconnections are occurring, CPU has not got
above 30%
We have about 25 users, but not more than 5 concurrent users at any time
Version is older.
Any guidance appreciated

Subject: Frequent disconnections occurring now
Hi
All our current users are reporting frequent disconnections and slow service
from Guacamole
I performed the usual maintenance recently, stop / start server, and
rollover the docker images which usually clears the issue, but its not
fixing this now
Any ideas of where to look?
Guac has been in service for about 3 years now. I am keen to upgrade but
that's another thread.
Thanks
Roland
