05:26 <****> darkelite: stfu and goto sleep
05:26 <****> in terms to how the shared memory is accessed
05:27 <****> either way there are logically two queues, the "hardware" and the software
05:27 <****> Nitrate: don't let me command the forces
05:27 <****> you shutup and go to bed..
05:27 <****> with the hardware, you think of how serilization day affects how your hardware queue will be used
05:27 <****> with software, you think about what you do when there is congestion at a high level, classifying packets, etc
05:28 <****> darkelite: i just wakeup, stfu:P
05:28 <****> and if you changed tx-ring, with tx-ring-limit under the interface, there will be changes in cpu usage
05:28 <****> and has to be proportional to bandwidth of the interface itself,
05:29 <****> lol
05:29 <****> Nitrate: you ate curry today
05:29 <****> lol
05:29 <****> going to bed
05:29 <****> lol

05:32 <****> my co workers make fun of me because i do not like chinese/indian/thai etc
05:32 <****> id rather just not blow my toilet up later :)
05:33 <****> :)
05:37 <****> Unter_, you need to find some ujarati food then
05:37 <****> Gujarati
05:39 <****> "It's rare to pass the CCIE lab exam on the first try. But that's what happened to Wendell Odom, who holds CCIE No. 1624. He passed the exam in 1995 after studying for one day."
05:39 <****> o.0
05:39 <****> ass
05:40 <****> he lied
05:40 <****> one day of study? pfft
05:40 <****> dwxreaper: that reminds me.. if you need a good book to read for QoS, read Odom's QoS Exam guide
05:40 <****> it's awesome
05:41 <****> Nitrate: http://www.networkworld.com/news/2006/022006-widernet-ccie.html?page=1 some dumb article
05:45 <****> one day of study? right
05:45 <****> if you discount maybe he worked in the industry for X years
05:47 <****> he's the author of the CCNA book
05:47 <****> and was teaching a class that was recommended for the CCIE prep at the time
05:50 <****> bah
05:58 <****> what is he talking about in that article, i'm lucky i got a ccie exam that focused on ibm protocols, and not apple or DECnet
06:05 <****> in single port forwarding in a router, how can it make a distinction between 2 services running on the same port numbers, i.e port 80 httpd, but one request goes to machine 192.168.1.102 and the other to 192.168.1.105 lets say
06:05 <****> Claudio32m: you can't
06:06 <****> bingo
06:06 <****> just spent an hour chatting with linksys about it
06:06 <****> she said you can
06:06 <****> you need at least 2 public ip addresses
06:06 <****> right
06:06 <****> i told her i had 1 static ip
06:06 <****> http could be a special case where you can create a http proxy and use host headers
06:06 <****> ah with a linksys i think they have some port "triggering" thing, that works slightly different.
06:06 <****> but thats application level
06:06 <****> not port forwarding
06:07 <****> ok
06:08 <****> you can host more than one website on a computer, do you really need 2 webservers?
06:08 <****> can any one filter router generated traffic? I'm trying to use a route-map with set lo0 for ip any any traffic match
06:09 <****> what router model
06:09 <****> 3725
06:09 <****> hmm
06:09 <****> i dont know if that has COPP or not
06:09 <****> i think it does
06:09 <****> lockdown - virtual hosts?
06:09 <****> yeah
06:09 <****> yeah thats not it though
06:09 <****> i was thinking other applications
06:09 <****> like ssh
06:09 <****> lets say someone types ssh machinea.com
06:10 <****> Unter_, what about the route-map? i saw it in a lab but it's not really working :/
06:10 <****> and ssh machineb.com
06:10 <****> i want a to go to .101
06:10 <****> and b to .102 for example
06:10 <****> Mahmoud: you have to apply the route-map to the router
06:10 <****> local-policy iirc
06:10 <****> Claudio32m, nope.
06:10 <****> nemith, i did by "ip local policy route-map-name"
06:10 <****> right
06:10 <****> Mahmoud: route map applied to where
06:10 <****> Claudio32m, yeah, your going to need a 2nd IP then
06:10 <****> cool thats what i thought
06:10 <****> ah
06:10 <****> Mahmoud: that match router generated traffic
06:11 <****> there's no way for a server to process the the request and split it
06:11 <****> sshd can't do it?
06:11 <****> nemith, but i still can (say) ping neighboring routers from the local router console + bgp/ospf work fine
06:11 <****> huh?
06:11 <****> Mahmoud: should
06:11 <****> nemith, so this is not to block such thing?
06:12 <****> Mahmoud: one of the brians favorite tricks is how to make traceroutes always reply with the router loopback address
06:13 <****> what about blocking locally generated traffic? is this right way? i'm confused
06:13 <****> right way == a way that works
06:14 <****> blocking it? it could work
06:14 <****> and pinging neighbores would fail since they will be sent to lo0, right?
06:15 <****> depends on your route-map
06:15 <****> you just need a deny route-map stanza
06:16 <****> ahhh
06:16 <****> and then we won't even need "set int lo0" ?
