I've been noticing I've been seeing a occasional white flash on part of my display.

Hi, I, out-of-hand, attributed this to my Time Capsule finishing its back up. This morning I checked my console and found this message. Never seen this type of message before.


1/22/12 5:48:41.517 AM Firewall: java is listening from ::ffff:0.0.0.0:0 proto=6


Can some tell me what this is and if it's related to that random flash?

iMac, Mac OS X (10.7.2), 2Tb Time Capsule; iPad2 32GB Wi-Fi

Hi,

I also started getting these "flashes" but i couldn't see what it was. I could make out that something is asking for permission to access incoming connections to computer but it was accepted before i could respond. This log "java is listening from :fff......" is definitely responsible for these flashes as i have checked it in the logs. Only problem is why is firewall allowing "java" to listen from this port. I should be able to deny it but that flash just goes away within a sec. Also in the firewall pane this "java" isn't even listed ! so there is basically no way i can remove it thereby denying it the incoming connection permission. This feels like some sort of intrusion to me coz this "java" doesn't allow me to deny it this listening permission, even in the firewall pane. I hope someone have an answer to this. i dont like some random application listening on some port which cant even be removed from firewall pane in system preferences.

I received an email from my Internet service provider on the 9th stating that I might have a bot. When I called them they said it was something called backdoor_php_groupb so I looked through all my logs and I saw that new line saying the same thing that java was listening from the fff place you listed above. I have never seen this before either. I tried to look up that bot and did not find the exact wording of it. Im frustrated and not sure what this java is listening thing is. Any developers know?

Hello all,

Ive been noticing this too. I went through my logs and got the same ''Java is listening to port...'' message.

Im a bit concerned about this too.


Can somebody atleast tell me if the JAVA on my machine is listening to a particular port or something external is listening to a port in my computer. Im a noobie when it comes to computer networks, dont mind if the question sounds dumb.

Im really concerned about this...

I had the same firewall log messages appearing in console. In system.log there were messages about com.facebook.videochat.updater right before the 'java is listening' messages. Seems that other people have found out the same thing:

Removed that updater daemon by running in Terminal:


launchctl remove com.facebook.videochat.<username>.updater

rm ~/Library/LaunchAgents/com.facebook.videochat.<username>.plist

I've been noticing I've been seeing a occasional white flash on part of my display.
