I've tried this. Still no joy, i.e. no response to
rxdebug -version <my-ip-address> 7001
while Application Firewall is running. (I've also seen direct evidence
that the firewall gets in the way of callbacks.)
I've even tried to sign afs.kext, just in case my hunch about port 7001
belonging to the kernel extension rather than to afsd is relevant. Didn't
My reading of Apple's own documentation (cf.
) is that the Application Firewall will take the identity of the signer into
account and that self-signed certificates, at least, won't work unless they've
explicitly been configured as trusted for code signing. (Ad hoc signatures
aren't really mentioned in that document.)
There are a few more experiments I can think of, but I'm not sure they are
worth my time right now.
