Re: [tor-relays] «Possible compression bomb» from Authority?
Hi, I get these warnings from time to time too. I believe they are rather benign, though I wonder how a document with a 25:1 compression ratio can happen in practice. > Interestingly it's the dirport that > ie requested. I thought the dirport is no longer in use - do the > authorities still offer it? Authorities still provide a dirport, and relays are supposed to use it over a tunneled directory request. I believe some authority operators put varnish (or some other caching reverse-proxy) in front of their dirport, to limit the load of serving those files. At the very least, it reduces the amount of crypto required (none vs an OR connection), for data which is already public and signed anyway.

We see the compression bomb warning from time to time The address seems to be longclaw. Interestingly it's the dirport that ie requested. I thought the dirport is no longer in use - do the authorities still offer it? pgptPL7q2q_s7.pgp Description: Digitale Signatur von OpenPGP ___ tor-relays mailing list tor-relays@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays
