Re: Am I missing something about portsentry?

It should not take a kill and restart or even a kill -HUP of portsentry,
but, removing from the portsentry.blocked.X files and then deleting the
route should reopen access for the target/source in question. Depending
upon the OS, the dead route points the offender to 127.0.0.1, so:

route -delete target-ip 127.0.0.1 should remove that also.

Thanks,
