TCP checksums absolutely can and do fail to protect you from in-flight corruption of data. I've seen this on several occasions over links with non-zero BER (i.e. any real-world link). A two-bit error in a single packet will not be identified unless you're using HTTPS or SSH or similar, with strong transport-layer hashes. FWIW I saw it with very, very large downloads but it can obviously happen with smaller data, just with a lower probability. _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
