Exclamation Incoming Connections?

I am about halfway through adding my collection to Calibre to use on my ipod with Stanza - I have not transmitted anything yet - just trying to get my 1000+ collection sorted.
I recieved a popup from McAfee today (after about 2 days of solid use) warning me of Calibre trying to accept incoming connections.
I couldnt find anything that told me why this would be happening and Im a bit concerned about the possibility of hackers finding their way in.
Is this normal? What would Calibre be trying to accept?
Are there any security risks? Thanks for any answers

I don't run it but if you had the content server running, it would obviously be accepting some connections. The best way to set things up from a security standpoint will hopefully be answered by others.

Another time it will accept connections would be when itis fetching news.

I would expect these to be outgoing connections? Only the Content Server should need incoming connections.

Note that if Stanza is going to eb used as the e-Reading device, then you would almost certainly want the Content Server to be running to be able to transfer books to Stanza (the USB cable is not an option in this case). When running the Content Server, then calibre needs to be able to accept incoming requests from Stanza for book catalogs and books.

I get that outgoing would be required - what i query is that McAfee identified incoming as stated in the screen shot.
So I guess i need to know in what instances would the calibre server require to connect with my PC, without me initiating anything?

The content server accepts incoming connections, it has to to function. If you are using Stanza, the stanza will be trying to connect to the content server on your computer, which is an incoming connection.

I think there may be a misconception here! We are talkinga bout the Calibre Content Server (not the Calibre server on the internet) which is part of the Calibre software running on your PC. This allows Calibre to act as a server to software such as Stanza so that Stanza can obtain a catalog of the books in your Stanza library and then request the ones you pick to be downloaded to Stanza on the iPhone.

Whether the Calibre Content Server is run or not is configured under Caliber Preferences->Content Sertver. However as was said earlier you will need this to be running to enable the transfer of books between Stanza and Calibre.

Just to update - the content server wasn't running at the time - which is why I was concerned - havent had it reoccur - even when I was running the server to transfer. Ran a full check on my computer and couldnt pick up any intrusions so I am going to assume it was benign.
A security vulnerability by using Calibre might be something to consider however.
