After instantiating the SDN Hub Tutorial (Renamed as SecRevFramework):

Install: gedit, idle, lighttpd, sslstrip, nmap, python_scapy, netifaces, php5-cgi Install: netifaces (sudo pip install netifaces)

sudo service lighttpd force-reload (failed--don't know why

Starting lighttpd:

files: /etc/lighttpd/lighttpd.conf and /var/www/html/index.html
# /etc/init.d/lighttpd start    
# /etc/init.d/lighttpd stop

Issues:

1. Serialization issues often occur if a required field is set to none. Displayed on terminal: File "/home/ubuntu/ryu/ryu/app/SecRevCntrl/Ryuretic.py", line 398, in _send_packet pkt_out.serialize() File "/home/ubuntu/ryu/ryu/lib/packet/packet.py", line 73, in serialize data = p.serialize(self.data, prev) File "/home/ubuntu/ryu/ryu/lib/packet/ethernet.py", line 67, in serialize

Problem: fields['ethtype'] was set to None

2)Serialization issue: Terminal Displayed: File "/home/ubuntu/ryu/ryu/controller/controller.py", line 214, in send_msg msg.serialize() File "/home/ubuntu/ryu/ryu/ofproto/ofproto_parser.py", line 203, in serialize self._serialize_body() File "/home/ubuntu/ryu/ryu/ofproto/ofproto_v1_3_parser.py", line 2374, in _serialize_body a.serialize(self.buf, offset) File "/home/ubuntu/ryu/ryu/ofproto/ofproto_v1_3_parser.py", line 2743, in serialize offset, self.type, self.len, self.port, self.max_len) File "/home/ubuntu/ryu/ryu/ofproto/ofproto_parser.py", line 220, in msg_pack_into buf += struct.pack(fmt, *args) error: cannot convert argument to integer

Solution: Problem: fields['ethtype'] set to 2054 instead of 0x0806 For Craft packets, require a newport vlaue.

3. Common Error to crafting packet: error: cannot convert argument to integer Make sure all fields are filled

4. TypeError: 'NoneType' object is not iterable Make sure you are returning fields and ops to your calling method.

5. Getting CGI to work is painful.

6. Need to upload the update lighttpd.conf file for enabling php and cgi.

Fixes: Ryuretic.py

1. line 228, 233: Look to remove pkt. May not need to send the entire thing.
2. line 319: Replace pkt['ip'] with fields['ip']
