In my writing, 2006 Lost

EstupiƱal
Ana Cecilia Vidales, the high, white, skinny and good grades. It was not like the asshole of Ursula Machuca, ugly, asshole, let alone as Elena, fat, pendejisima, with mien of a bitch. Definitely my tastes were well calibrated, Ana Cecilia was my ideal girl. Whenever

had a chance was shielded my stitches and my skills Perron. Even with my orthopedic shoes made, I was running so easy to catch when we played cops and robbers boys against girls. Chale.

The curious thing is that I never could get her to notice me, it was perhaps my casquetito hairstyle? my feet crooked? vosal my Frenot with integrated? or detecting a bad vibe from me?? Bitch never know. Ana Cecilia Vidales EstupiƱal because because.

Now, sitting here remembering all those little details that snatches big to keep it to my sweetheart, is that memory ... that afternoon, we were out of classes in the afternoon, and together with the Geovanna, I started to scream "UGLY!" UGLY! " and hookers going to do? ... I remember shouting to the air (but god, I never yell at you) "ME VALE VERGA! (Of the first times he used the expletive). Because it .. Ana Cecilia .. why?! I was sentenced to drag this resort for the rest of my days with my little 9 years ...

ubiera I certainly committed suicide, thanks Seiya, thanks Link, for filling my empty days of the primary (and beyond).

Sad memories of love.

Soul Silver Rom For Desmume Ma

Avoid uncontrolled switches in our network DHCP server

meeting room a medium-sized (three consultants and a client ...)

[Consultant 1] Hey Joseph. I need to get off the mail to receive the latest version of PowerPoint.
[Customer] OK. Connect to this outlet.
[Consultant 2] Well, I too would be good to connect.
[Guest] You yourself ...
[Consultant 3] I can ... ?
[Guest] Yes of course.
[Consultant 3] As sockets are not free ...
[Consultant 1] Tranquilo Tomas, I have a switch ... Look what we connect to the wall and both of us to switch.
....
[outside voices] Do you have Internet? .. I do not, do you? ... I get an error the Excel ...

Meanwhile in the network operating room ...
[Engineer 1] Michael, I need the budget for next year's maintenance of radio links ..
[Engineer 2] Yes .. and you asked me yesterday ...
red light appears on the screen of monitoring systems
[Engineer 1] Shit. Gone is the office network of Teruel.

The emergence of a uncontrolled switch a network can bring you down and leaving no months of planning, configuration and stability of your network users.

You can not trust that users do not connect anything to the network (though always swear not to), so we have to control ourselves.

The main problem of connecting an uncontrolled switch in our network is capable of producing a change in the topology of the tree of STP . These changes can be subtle or cause problems (IP Telephony do not like the changes.)

midrange switches allow two actions to the problem: Ignore
  • STP protocol messages to send a non-controlled switch. Block
  • takes you connect a switch uncontrolled. Warn
  • via SNMP , the network operators.
In applying these policies is very important to have a network map with the physical connection of equipment, and that we should allow BPDU traffic on those links connected physically (whether active or disabled by STP) to avoid surprises pathways activated backup (before the fall of a switch can change bastente topology as the network that has been mounted).

To configure these protections simply must enter the settings spanning-treey securing activate these options.

In HP:
switch06 (config) # spanning-tree 1-47 BPDU BPDU-filter-protection

Avoid uncontrolled

One type consists of attacks that impersonate DHCP server on the network . So the team can force the traffic generated from computers with dynamic IP to pass through your network card (and capture the desired information.) Is a typical attack Man-in-the-Middle .

If a network is not going to use dynamic addressing can block traffic protodolo DHCP, but if needed we must allow this protocol. The current switches allow us to restrict this traffic so that only authorized servers (the people managing Systems) send this information has thus preventing intruders posing as DHCP servers.

Overall implementation of this security policy is as easy as:
    Enable Protection
  1. Identify DHCP server IP authorized to submit this protocol
  2. identify from which port will receive this traffic
Point 3 is usually more complicated, but generally for access switches protocol DHCP should only be reached by the uplink . This point will change depending on the network that we have assembled: we must take into account existing loops (the spanning-tree can give us a call at this point), etc. I advise to have a very clear network map indicating where the server and what are the roads that can track the traffic to reach the final customer. An example

an access switch HP brand. In other similar brands will be changing commands.

1. Activate the DHCP protection:
ACC-SW01 (config) # dhcp-snooping
2. Indicate that servers are the officers:
ACC-SW01 (config) # dhcp-snooping-server Authorized 10.10.10.10
ACC-SW01 (config) # dhcp-snooping-server 10.10.10.15 Authorized
3. Indicate from which port will accept this traffic (which is the way to get from our switch to the authoritative name servers). Ed access from a computer most likely be the uplink:
ACC-SW01 (config) # dhcp-snooping trust trk1 (we assume that the uplink is a trunk and called trk1)
This is the basic idea ... obviously complicate it:) Take

Throat Had To Be Drained

remote debug HTTP request

debug information from remote connection

debug commands on the routers / switches are configured by default send all information to the physical computer console. The problem comes when you need to get that information debug a remote computer that you connect via telnet / ssh. How can this information out on your screen and not the serial connector of the team? Stop
  1. debugs all you have. Forward
  2. your login information
  3. Enable debug you need

CISCO: cisco #

undebug all
cisco # cisco # terminal monitor debug dhcp
HP:
switch # no debug all
switch # debug destination session
switch # debug dhcp-snooping
