title: Fuzzing with SPIKE - generic_send_tcp error
body: <p>I know SPIKE is already outdated, but I have to do it in SPIKE.</p>
  <p>I am trying to do this <code>generic_send_tcp 0.0.0.0 8080 check_post.spk 0 0</code>
  bu I get that <code>generic_send_tcp: undefined symbol: s_string</code>
  Should I add sth or remove. I will add that two weeks ago it worked perfectly.</p>
  <p>My script looks like this:</p>
  <pre><code>s_string(&quot;POST&quot;);
  s_string(&quot; &quot;); 
  s_string(&quot;/&quot;); 
  s_string(&quot; &quot;);
  s_string(&quot;HTTP/1.1&quot;);
  s_string(&quot;\r\n&quot;);
  s_string(&quot;Content-Length:&quot;);
  s_blocksize_string(&quot;block1&quot;, 5);
  s_string(&quot;\r\n&quot;);
  s_string(&quot;Content-Type: application/x-www-form-urlencoded\r\n&quot;);
  s_string(&quot;\r\n&quot;);
  s_block_start(&quot;block1&quot;);
  s_string(&quot;login=&quot;);
  s_string_variable(&quot;a&quot;);
  s_string(&quot;&amp;password=&quot;);
  s_string_variable(&quot;a&quot;); 
  s_block_end(&quot;block1&quot;);
  s_string(&quot;\r\n&quot;);
  </code></pre>
