#Wing ftp server packet len too high code#

I'm an 25 year survivor of Enterprise IT, the co-host of the Packet Pushers Podcast and author of. I speak on data centre, SDN and WAN networking at a few conference. I have worked all over the world - Australia, Hong Kong, Fiji, Papua New Guinea, England, Germany, France and USA. I am CCIE Emeritus #6920 (and a bunch of other expired certifications including 3Wizard) and I still do real hands work for customers. Update: Happy to keep answering questions, but please upvote the post and I will check in over the next or so. If you have questions on data networking, I'll will be checking out this thread over the Easter weekend until Monday 1200GMT and will do my best to be cynical, down beat, and apocalyptic about the future of IT Infrastructure. PS: I'm doing this because a few people asked me to. This was a great experience and hope I was able to answer everything. And special shout to people who said they love the podcast and the blog.

Update 20150405-2201UTC: checking out in local time. Will take more questions until PST0400 tomorrow. Update 20150405-1417: caught up on new questions (i think). So many great questions and I'm struggling to keep up.

Update 20150404-1153: back on deck, and will be checking in during the day. Update 2234UTC: Sleepy time! back tomorrow to answer questions if there are any more.

Update 1925UTC: questions getting tougher, having more beer to improve answers. #Wing ftp server read packet packet len too high update I'll try not ask you anything about the ACI fiasco, seems like that was quite. I have independent opinions and I generally choose to speak my mind. #Wing ftp server read packet packet len too high update.Print('Failed to open source file', source_file, ':', e, file=sys.stderr) With open(source_file, 'rb') as file_handle:īuffer = file_handle.read(FILE_BUFFER_SIZE) Print('File size packed into binary format:', buffer) Print('Sending file size to remote server.')

I know my code is still far from being a robust implementation, so I am looking for your opinions. During data transmission, both side of socket update a SHA256 object, and when transmission is completed, they calculate the hash digests and print them on screen. The client sends the size of file at first, then the content of file. The server listens to a specific port provided on command line, then the client connects to the server, and send a file to it. To learn network programming in Python, I have written a small piece of code which is constituted of 2 modules, a client and a server.
