I've had a handful of clients contact me over the last week with trouble using SCP (usually WinSCP) to manage their website content on my servers. Either they get timeout messages from WinSCP or a message saying they should switch to SFTP. After getting a few helpful users on the phone to run some quick tests, we found port 22 was blocked. When my customers contacted Frontier, they were told that port 22 was blocked because it is used to transfer illegal files. I called them, and got the same ridiculous excuse. Just a friendly heads-up to anyone from Frontier who might be listening, I have a few additional ports you may wish to block:
I wonder if their support is just confused, and Frontier is really blocking outbound tcp/22 to stop complaints generated by infected customers with sshd scanners. After all, most of their customers probably don't know what SSH is.
