Message: [QUOTE="=?ISO-8859-1?Q?Mickel_Gr=F6nroos?=, post: 1727516"] OK, here's what I want to do: When the Tkinter application I am writing starts up, it checks if certain files on the web exists and if so, it downloads them to a local directory replacing possible earlier copies of these files. So, what I mean by checking if the computer is online is that I want to check if I can access these certain remote files with urllib.urlretrieve(). If I can, then I download them. If I can't, I assume the computer is not connected to the Internet and I skip the update phase. The problem with just running urllib.urlretrieve() is that the execution of the script halts as there is no timeout available for Python 2.2.2. (I tried timeoutsocket.py to get this done, but that only worked on Windows 2000, not Redhat Linux 7.0. I also tried upgrading to Python 2.3, but that caused some other problems, especially with the gettext module and with the fact that my ISO-8859-1 encoded files needed a "coding" line.) So that's that. Anybody still got a few lines of code that would get this done on Python 2.2.2 on Windows _and_ Linux? Cheers, /Mickel G. [/QUOTE]
