Hi Nick, Guacd version 1.3.0 running native on Ubuntu 20.04 Apologies, I had read and understood that guacd should not be the problem and did not need restarting, but wrote that anyway for some reason. I had recently restarted it to change the loglevel.
Client has been complied with Postgres, RADIUS and LDAP authentication, although could not get RADIUS to work and is disabled. User is authenticated against LDAP, and database Groups match defined LDAP groups, so no users defined in local database, they see database defined connections based on LDAP group membership. This all works as expected. Thank you, Craig From: Nick Couchman <vn...@apache.org> Sent: 24 September 2021 14:42 To: user@guacamole.apache.org Subject: Re: Exhausted simultaneous connection error This message originated from outside your organization ________________________________ On Fri, Sep 24, 2021 at 7:48 AM Stratton, Craig <craig.strat...@pspsl.co.uk.invalid<mailto:craig.strat...@pspsl.co.uk.invalid>> wrote: Hi, I am continually running into this error and cannot seem to resolve it. “The Guacamole server is denying access to this connection because you have exhausted the limit for simultaneous connection use by an individual user. Please close one or more connections and try again.” There are no connections listed for the user when I look to close them. I have some connections set with default blank number of connections per user, some with 1 some with 10, but it happens on all of them. I can connect, disconnect, reconnect fine after creating a new connection, then if I try again the following day I get that error, even after closing properly. I have not set any of the guacamole.properties<http://guacamole.properties> file entries to override any defaults on number of connections, as the way I read the manual, there are no limits by default. If I stop and restart guacd and tomcat, it makes no difference and still cannot connect, it will just randomly start working again after some undetermined timeout? Just to note, here, guacd is not related to this issue, as the connection tracking, including simultaneous connections, is done by Tomcat/Guacamole Client. I say that only to note that restarting guacd isn't going to do anything for this. Restarting Tomcat should clear things out, but you shouldn't need to mess with guacd. That said, guacd logs may help you to determine if an unexpected connection is coming through, so might not be a bad idea to pay attention to those. What version of Guacamole are you running? What configuration - Docker or native, MySQL, Postgres, etc.? -NIck Public Sector Partnership Services Limited (PSPS) is a Local Authority Trading Company, wholly owned by East Lindsey District Council, South Holland District Council and Boston Borough Council in Lincolnshire.
