It should be.

Feel like opening a feature request in JIRA?

Hi,

This will make a bit more clear to me. At the moment it is just happening 
randomly ( I couldn't find out any pattern yet except the inactivity).
I will try to figure out when it happens so we can maybe reproduce it. I will 
also try to figure out if it can happen because of underlaying network issues. 
If I have some more info (or not if there is none...) , I will come back.

Hello all,

We are using guacamole for a couple of months now but we have some problems 
with SSH connections.
We connect to our customers with guacamole via a VPN tunnel. Sometimes we keep 
the SSH-session open but we don't use it for a while. Often the SSH-session 
freezes when we want to use it again. Is there some way to keep the SSH-session 
alive until we logout or until the session timeout kicks in?


Guacamole's session timeout only takes effect once all connections are closed. 
If a user has an SSH connection open, they should stay logged in, regardless of 
whether they are actively using that connection. As far as Guacamole is 
concerned, as long as the connection is open, the user is active.

What you describe sounds like a bug, assuming there isn't some underlying 
network issue causing the disconnect. Is this reliably reproducible? Do you see 
anything logged by guacd or Tomcat when the connection unexpectedly terminates?

Some additional information. After a couple of minutes the session wil 
disconnect with a message. Here is the rest of /var/log/messages

Feb 10 07:30:01  systemd: Created slice user-0.slice.

So after about 30 minutes the session is not be able to be used and a couple of 
minutes later it will be disconnected by Guacamole.

For us we need the SSH-session to be active till we disconnect it ourselves (or 
maybe after several hours of inactivity).

Could it be the SSH server itself that is timing out the session? If I
remember correctly, sshd does have client timeout settings.

Re: Timeout SSH session

Hi,

I did some tests. After half an hour of inactivity the session is not 
responding anymore. I did a ping on the same time but didn't had any packet 
loss.
We are using Guacamole 0.9.10 with MySQL (MariaDB) backend and LDAP 
authentication (to Active Directory) on CentOS 7.3.1611.
We are using Apache as proxy

Hi,

This will make a bit more clear to me. At the moment it is just happening 
randomly ( I couldn't find out any pattern yet except the inactivity).
I will try to figure out when it happens so we can maybe reproduce it. I will 
also try to figure out if it can happen because of underlaying network issues. 
If I have some more info (or not if there is none...) , I will come back.

Hello all,

We are using guacamole for a couple of months now but we have some problems 
with SSH connections.
We connect to our customers with guacamole via a VPN tunnel. Sometimes we keep 
the SSH-session open but we don't use it for a while. Often the SSH-session 
freezes when we want to use it again. Is there some way to keep the SSH-session 
alive until we logout or until the session timeout kicks in?


Guacamole's session timeout only takes effect once all connections are closed. 
If a user has an SSH connection open, they should stay logged in, regardless of 
whether they are actively using that connection. As far as Guacamole is 
concerned, as long as the connection is open, the user is active.

What you describe sounds like a bug, assuming there isn't some underlying 
network issue causing the disconnect. Is this reliably reproducible? Do you see 
anything logged by guacd or Tomcat when the connection unexpectedly terminates?

Timeout SSH session

If we use a SSH-application like Putty or SecureCRT we don't have these issues.
