Hey guys, I have just started using IP tables and was wondering if anyone could direct me to any good online resources as I am totally new to this. Thanks. (1 Reply)
Trying to create a whitelist to limit bandwidth. My sync speed is 1536/256 kbps.
Simple rules in order:
1. Do not limit (or set to 1536/256) MAC 00:00:00:00:00 (computer is in 192.168.1.0/24).
2. Do not limit (or set to 1536/256) MAC 00:00:00:00:01 (computer is in 192.168.1.0/24).
3. Do not... (1 Reply)

Hi,
On the IPTABLES, I did iptables --flush. I want to start fresh. Now I only want two things. Allow one ip address to this server. Allow port 443 as incoming from every where. Please advice how to do this.

packet.pkt
PACKET.PKT(1) packet.pkt 1.0.1 PACKET.PKT(1)NAME
packet.pkt - Pkt module
DESCRIPTION
Provides the object for a packet and the string representation of the packet. This object has an attribute for each of the layers in the
packet so each layer can be accessed directly instead of going through each layer. To access the nfs layer object you can use 'x.nfs'
instead of using 'x.ethernet.ip.tcp.rpc.nfs' which would very cumbersome to use. Also, since NFS can be used with either TCP or UDP it
would be harder to to access the nfs object independently or the protocol.
Packet object attributes:
Pkt(
record = Record information (frame number, etc.)
ethernet = ETHERNET II (RFC 894) object
ip = IPv4 object
tcp = TCP object
rpc = RPC object
nfs = NFS object
)
CLASSES
class Pkt(baseobj.BaseObj)
Packet object
Usage:
from packet.pkt import Pkt
x = Pkt()
Methods defined here:
---------------------
__str__(self)
String representation of object
The representation depends on the verbose level set by debug_repr(). If set to 0 the generic object representation is returned. If
set to 1 the representation of is condensed into a single line. It contains, the frame number, IP source and destination and/or the
last layer:
'1 0.386615 192.168.0.62 -> 192.168.0.17 TCP 2049 -> 708, seq: 3395733180, ack: 3294169773, ACK,SYN'
'5 0.530957 00:0c:29:54:09:ef -> ff:ff:ff:ff:ff:ff, type: 0x806'
'19 0.434370 192.168.0.17 -> 192.168.0.62 NFS v4 COMPOUND4 call SEQUENCE;PUTFH;GETATTR'
If set to 2 the representation of the object is a line for each layer:
'Pkt(
RECORD: frame 19 @ 0.434370 secs, 238 bytes on wire, 238 bytes captured
ETHERNET: 00:0c:29:54:09:ef -> e4:ce:8f:58:9f:f4, type: 0x800(IPv4)
IP: 192.168.0.17 -> 192.168.0.62, protocol: 6(TCP), len: 224
TCP: src port 708 -> dst port 2049, seq: 3294170673, ack: 3395734137, len: 172, flags: ACK,PSH
RPC: CALL(0), program: 100003, version: 4, procedure: 1, xid: 0x1437d3d5
