 Description  « Hide
Was playing with dumping packet contents to screen with pyogp when I found errors. Since we'd been testing with limited numbers of packets it only showed up after we started looking at larger numbers: packets would be coming in with no valid ID. E.G., byte 6 was NOT oxff.

This showed up with the pyogp library and with the normal OGP GPL viewer, when examing incoming packets using tcpdump. Examples:

time = 2008-10-20 10:43:43.912675 Counter = 29(<type 'exceptions.AttributeError'>, AttributeError("'NoneType' object has no attribute 'name'",))
packet == None, and msg_buf is: \0xc0\0x0\0x0\0x0\0x10\0x0\0xc\0x0\0x1\0xea\0x3\0x0\0x2\0xe6\0x3\0x0\0x1\0xc4\0xf3\0x3\0xa\0x5\0xbe\0x9\0x0\0x1\0x38\0xd0\0x39\0x11\0xa7\0xad\0xae\0x2f\0x8b\0xc2\0x45\0x57\0x46\0xd5\0x23\0xa\0xb3\0x3\0x0\0x2\0x9\0x3\0x0\0x3\0x20\0x41\0x0\0x2\0x20\0x41\0x0\0x3\0x3f\0x3c\0xd2\0x1\0x20\0x41\0x0\0x38\0xd\0x5\0xbe\0x9\0x50\0x8\0x2\0x10\0x10\0x1\0x0\0x4\0x64\0x64\0x0\0xf\0x54\0x0\0x1\0xf4\0x2f\0xbf\0x39\0xb7\0x5b\0x8d\0x55\0x54\0x97\0x66\0xf7\0x10\0x87\0x44\0xe3\0x1\0xbb\0x32\0x13\0xd5\0xfd\0x80\0xa8\0x5e\0xa9\0xc3\0xd5\0x93\0x64\0x2f\0xc7\0x4f\0x0\0x1\0xca\0xc4\0x95\0x0\0x1\0x1\0x0\0x7\0x20\0x41\0x1\0x0\0x3\0x3f\0x0\0x3\0x20\0x41\0x1f\0x0\0x3\0x3f\0x0\0x3\0x1\0x0\0x1\0x20\0x0\0x3\0x1\0x0\0x1\0x20\0x0\0x4\0x40\0x0\0x10\0x1\0x0\0x43\0xb\0x5\0xbe\0x9\0x0\0x1\0xb1\0x75\0x2d\0xf2\0x93\0xa3\0xe8\0x94\0x66\0xc7\0x67\0xad\0xbd\0x72\0x21\0xb4\0xbf\0x3\0x0\0x2\0x9\0x3\0x0\0x3\0x20\0x41\0x0\0x2\0x20\0x41\0x0\0x3\0x3f\0x3c\0xd2\0x1\0x20\0x41\0x3f\0x0\0x1\0x20\0xc1\0x0\0x34\0xd\0x5\0xbe\0x9\0x50\0x8\0x

totally messed up. there's a flaw in pyogp packet handling that I can't quite figure out, and I got confused. Sorry to waste everyone's time.
