Fear not, the PubSub Agent
Posted 09 April 2008 - 08:17 AM
Here's a better answer to the original question: Whenever one of those keychain alerts comes up for an app you don't recognize, flip open the "Info" section and click on the pop-up to see where on disk the application is. If it's in the "System" folder of your startup disk (as PubSubAgent is) then it's a core component of the OS and you can allow it.
(On 10.5 these sorts of alerts aren't supposed to come up at all for system apps, because they've already been code-signed by Apple; but I've seen it happen occasionally anyway.)

The sensible thing to do, is to always check what the application or process does.
This isn't because the Mac is any more or less prone to attack. It's because most of the recent exploits that have targeted the Mac platform relied in part on social engineering tricks.
The alert should at the very least act as a 'wake-up call' to the user that something unusual is going on.
However, once a process has been identified as benign, I'd agree that clicking 'Always Allow' is a good way to avoid having to deal with that alert in the future.

Now I am constantly bombarded by this PubSub Agent alert, at least once evey five minutes, and there is no check box that says "Always Allow." Am I missing something or forgot to turn something on in preferences? I'd love to get rid of this annoying problem as it is constantly affecting my work.
Thanks in advance for any help you can provide.

Why anyone would changed the .plist files of the PubSub Agent is beyond me.

I ran across two separate articles that said "just click allow" and don't worry about it. I would recommend anyone who is running a firewall and gets a warning like this should first find out what the program is supposed to do and then rely on your own judgement, and don't be so quick to approve anything just because someone tells you it's safe. So I agree with Snej - don't automatically click "Allow" that defeats the whole purpose of the alert.
Lastly I strongly recommend LittleSnitch to monitor your outgoing traffic. You should know who your computer is talking to and LittleSnitch allows you granular control over a program. So you can prevent it from going to one destination, but allow it to go to another.

Also, PubSub does a lot more then just load in RSS feeds. For some reason iPhoto crashes when the PubSub agent is removed (somebody want to shed some light on this?).
