Application start delayed with internetless network connection
Hello,
I hope I'm posting this in the right category, but I have a somewhat interesting problem.
When I'm inside a network with no Internet connection, some applications are taking way longer to start up than with Internet/disabled connection. I first noticed it in April, when I made a LAN-Party with some friends in a place, where simply no Internet was given. Call of Duty 2 or Empire Earth 2 (both through wine) took way longer to start up (sticking on the splash screen) when I was just connected to our network, turning it off/pulling the LAN cable was a temporary workaround but it is kinda annoying. This problem also occurred to some native applications like the Processing IDE. Today I reproduced this issue in my home network by just giving myself an invalid IP adress. It happens on both my PC and Notebook (both have Arch Linux x86_64 along with GNOME 3, all up to date), but interestingly though, a friends notebook (Arch Linux i686 but also with GNOME 3) didn't have the same trouble, so what could this all be about?
Greetings, Max

Re: Application start delayed with internetless network connection
Have you correctly set your hostname? What's the output of...
hostnamectlOffline

Re: Application start delayed with internetless network connection
It seems to look right...
By the way, I'm still new here, how can I put this output in a sort of container?
mawalla@arch-mwpc ~> hostnamectl

Put it inbetween [code] [/code] tags.

Your hostname appears to be correct, you'll have to wait for other suggestions I'm afraid, I don't have any more.

Re: Application start delayed with internetless network connection
Probably some resolver issue - the process will attempt to call home and either be unable to resolve the hostname (give up immediately) or "for some reason™" get an IP, try to call that and wait for the timeouts.
You could wireshark it to see whether that is the case resp. to figure which host it tries to access and then see whether you can resolve it w/o internet connection.
The key might be a local DNS cache or server and/or the resolve.conf updates to your connection state changes. This might relate to different network managing services (eg. networkmanager ./. netctl ./. systemd-networkd ...)
