From 3c9066fce54b78cc8b46e82eba033aaa373cdef1 Mon Sep 17 00:00:00 2001 From: Marc Hoersken Date: Tue, 17 Mar 2020 10:36:25 +0100 Subject: tests: make Python-based servers compatible with Python 2 and 3 Update smbserver.py and negtelnetserver.py to be compatible with Python 3 while staying backwards-compatible to support Python 2. Fix string encoding and handling of echoed and transferred data.
