mdnsresponder and configd

SolRayz · Dec 29, 2007, 01:03 PM

Everytime I boot up now I recieve these annoying messages that say

Quote:

Do you want the application "configd" to accept incoming network connections

and

Quote:

Do you want the application "mdnsresponder" to accept incoming network connections

If I click on deny on both I have no inernet connection. Also if I go to System Preferences and set my Firewall to "receive all incoming connections" essentually turning my firewall off these messages stop occuring on reboot.
I think this all happened after trying to recalibrate my MBP battery but I am not sure.
Anyone have any ideas?

I assume you are on Leopard? Did it come pre-installed and if not how did you install it?

SolRayz · Dec 29, 2007, 01:18 PM

Yes I did a fresh install and all was good.

I also noticed that when I reboot it doesn't remember my wifi connection. Anyone?

Same problem here under Leopard. If I don't allow it I don't get a good IP from my router (UI get one of the 169.x self-assigned IPs), though, and the connection fails. Real annoying.

I get exactly the same. Mine started after i took out the battery of my G4 Powerbook running 10.5.2, to clean the screen and keyboard.

interconnect · Mar 20, 2008, 01:57 PM

same exact issue here.. i randomly started getting the messages.. i think they started appearing after a recent update. it also forgot my wireless connection, which i just retyped in my password and was all set there, although i still keep getting the prompts when i boot-up. i tried clearing out all the programs listed in the allowed application list and restarting in which neither mdnsresponder or configd were added and still continue to prompt me when i boot-up/login. i also had qmasterd doing the same thing, but went away after i cleared the allowed applications list and hasn't prompted me since for that one.

All of a sudden I am getting those same two messages every time I boot to Leopard. There was a security update that I just applied today, maybe from that? I have also had it occasionally forget my wireless connections over the past few weeks. Very annoying. Anybody figure out where these messages and forgetfulness came from?

kaz219 · May 9, 2008, 07:57 AM

Same here on a PowerBook with Leopard 10.5.2.

junior77 · May 9, 2008, 08:24 AM

Same exact problem....happened when the battery went dead.

The only way around it was to do a re-install. Hopefully, someone else here will post a real way to correct the problem from re-occurring again.

It sounds like a bad Application Firewall configuration (missing the exceptions that allow configd, mDNSresponder, and racoon). Restore from the defaults:

sudo cp /usr/libexec/ApplicationFirewall/com.apple.alf.plist /Library/Preferences/com.apple.alf.plist

So, basically delete the plist file above and reboot/restart? I'll have to keep this in mind if it happens again.

Hi,
I had the same problem with may Macbook Pro. Thanks for the hints I found here, yesterday, after two hours the problem was solved. Although I am not sure which one of the steps was the one that finally helped and wether the procedure is going to help others, here is what I did:

1. Reset the com.apple.kerberos.kdc certificate as described in http://support.apple.com/kb/TS1245

2. Delete the ApplicationFirewall Preferences (located in Library/Preferences/com.apple.alf.plist)

3. Allow the system processes mdnsresponder, configd and racoon in the firewall (click "plus", then alt-shift-g to access the system processes, then write /usr/sbin, then choose the three processes, add)

4. As I run Little Snitch, I did two additional things: Allow these processes in Little Snitch as well

5. Update from Litte Snitch 2.0.1 to 2.0.4

Reboot after every step. After one of the first steps, the internet connection worked well, but the questions to allow the processes remained. After the modifications with Little Snitch, everything was fine again.

Hope it helps someone else as well.

Cheers Sara

HI,
I solved with a custom com.apple.alf.plist.

You have to delete all items in exceptions key and add child to firewall key with configd, mDNSresponder, racoon, ntpd and krb5kdc.

I uploaded to Mediafire a zip with the corrected .plist and an Apple script with its source for newbies.
