# TCP response matching on long replies, and SFTP keyboard-interactive logins

A TCP monitor with a response pattern failed on servers that answer with one very long line — a minified HTML or JSON body — and an SFTP monitor could not log in to servers that only offer keyboard-interactive password prompts (OpenSSH with PasswordAuthentication off). Both were our bugs. TCP replies are now matched up to 1 MiB, and an SFTP password is also offered through keyboard-interactive prompts.
