getting back negative results in loop

You correctly look for the string sshd line wise, but search the strings TCP and UDP in the whole file. As there is one line with UDP and 123, every call to inrange(file, "UDP", int(my_string)): will return true even if there is a TCP in current line.

You should extract the proto from the current line. Something like

    proto = newline[:3]
    if (proto in ['UDP', 'TCP']) and inrange(file, proto, int(my_string)):
        print("Line " + str(plusOne) + " is in range" + " " + my_string)    
    else:
        print("Not in range")
