Hi I am running the new OSX Server 3 on my Mini MAC Server

Customer Question

Hi I am running the new OSX Server 3 on my Mini MAC Server with Maverick. We have updated all of the possible updates and system running great. Our issue is keeping the idle time open with the VPN. We have tried to change the set time from 7200 seconds in to 86400 and also 2,592,000 as even though there are no packets being sent we still need the vpn to remain open. As you can see below not only do we now have every protocol we have entered incorrectly the system is still only staying on for 7200 seconds. 1) How do we remove the additional copy from the system and 2) What script should we write to get the correct sends of 2,592,000 or is there another max parameter? vpn:Servers:com.apple.ppp.l2tp:PPP:DisconnectOnIdle = 86400 vpn:Servers:com.apple.ppp.l2tp:PPP:AuthenticatorEAPPlugins:_array_index:0 = "EAP-KRB" vpn:Servers:com.apple.ppp.l2tp:PPP:AuthenticatorACLPlugins:_array_index:0 = "DSACL" vpn:Servers:com.apple.ppp.l2tp:PPP:VerboseLogging = 1 vpn:Servers:com.apple.ppp.l2tp:PPP:IPCPCompressionVJ = 0 vpn:Servers:com.apple.ppp.l2tp:PPP:ACSPEnabled = 1 vpn:Servers:com.apple.ppp.l2tp:PPP:LCPEchoInterval = 60 vpn:Servers:com.apple.ppp.l2tp:PPP:LCPEchoEnabled = 1 vpn:Servers:com.apple.ppp.l2tp:PPP:AuthenticatorProtocol:_array_index:0 = "MSCHAP2" vpn:Servers:com.apple.ppp.l2tp:PPP:DisconnectOn Idle = "86,400" vpn:Servers:com.apple.ppp.l2tp:PPP:AuthenticatorPlugins:_array_index:0 = "DSAuth" vpn:Servers:com.apple.ppp.l2tp:PPP:Logfile = "/var/log/ppp/vpnd.log" vpn:Servers:com.apple.ppp.l2tp:PPP:Disconnect On Idle = "2,592,000" vpn:Servers:com.apple.ppp.l2tp:PPP:DisconnectOnIdleTimer = 7200 Kind Regards Carlo

Hello,
I am Pete, and I'll be happy to assist with your question today.

 

After changing the set time, ensure you restart the VPN servers and routers at both ends of the VPN for the changes to take effect.

 

Let me know if that helps.

 

Pete.

Hi Pete


 


We have done the suggested protocols.


 


We thought things were looking up hence the quick rating.


 


2 Android 4.1 and iPhones all disconnect at exactly 70 minutes.


 


So it must be at our end.


 


Here is the command prompt dump;

We are only running pptp with PPP as this seems to sit more comfortably with the staff's Smartphones.


 


Any thoughts as to why we disconnect at 70 minutes?


 


Doesn't "vpn:Servers:com.apple.ppp.pptp:PPP:DisconnectOnIdle = 7200" actually mean 7200 seconds or am I missing something?

Hi Carlo,

What type of server are you connecting to -

is it a Mac server or a Windows server?

Customer: replied 11 months ago.

Hi Pete


 


OS X 10.9 (Build 13A603)


Server 3 (Build 13S440)


 


Model Name: Mac mini


Model Identifier: Macmini6,2


Processor Name: Intel Core i7


Processor Speed: 2.6 GHz


Number of Processors: 1


Total Number of Cores: 4


L2 Cache (per Core): 256 KB


L3 Cache: 6 MB


Memory: 16 GB


Boot ROM Version: MM61.0106.B03


SMC Version (system): 2.8f1


 


Does this help?


 


Carlo

This is the spec for one server, what is the spec for the other server that the VPN is connecting to?
Customer: replied 11 months ago.

We only have iPhones or Android Phones connecting in to this one server via VPN, no other servers are being connected to or from.


 


Carlo

Expert:  Pete replied 11 months ago.
Ok, the parameters you need to check are

vpn:Servers:com.apple.ppp.pptp:PPP:DisconnectOnIdle
vpn:Servers:com.apple.ppp.pptp:PPP:DisconnectOnIdleTimer

 

If they have been adjusted but the VPN still disconnects after 70 minutes, then it is likely that there is something else causing the disconnection, e.g. a power saving setting that is putting the Mac to sleep, or a setting on the router, or some other external cause.
