Existing network-trace-based models focus on text-based and hybrid protocols, using tokenization and some other heuristic rules, like field identification, to perform reverse engineering, which makes it hard to apply to binary-based protocol.
However, how to extract format information from network trace data for binary-based protocol still remains a challenging issue. Many models have been proposed to generate field boundary, field semantic, state machine, and some other format information from network trace and program execution for text-based protocol and hybrid protocols. Knowing what things have been tried and failed to have an effect can help bug hunters at Realmac narrow down their search too.Network communication protocol reverse engineering is useful for network security, including protocol fuzz testing, botnet command infiltration, and service script generation. If you have tried doing this sort of thing already, then don’t bother doing it again obviously – but do tell us a few of the things you have tried over the past three months. But I know that removing the space fixed the problem. I’m not sure if the problems started occurring when I accidentally typed the extra " ", or perhaps the host just stopped being tolerant of the extra space one day. So I deleted everything, but when re-entering it from scratch I took a shortcut to copy from the old setup – and the “Path” had an extra space character. I knew my password was right, I knew URL was right, and all the rest looked just like the working setup to the same host in Coda. Once, a long time ago, I had an FTP issue I couldn’t fix for the longest time. No copy/paste from the broken one – just in case. Then, I’d try deleting all of the Publishing settings, and re-adding FTPS and SFTP again by hand. It’s worth trying even if things are working. Sometimes one is very fast and the other is very slow. Some hosts have much better support for FTPS than for SFTP and of course, vice versa.
FTP is outside of my area of influence, but I do FTP a lot of files, so I’ll tell you what I do when this kind of thing happens to me:įirst, I’d try a different protocol, if your hosting company supports it.
