[00:19]<frvfnfv>does pbr add significant load to a device?
[00:21]<yrdoul>pay by results?
[00:22]<yzrmynx>Consider an HTTP client that wants to retrieve a Web document at a given URL. The IP address of the HTTP server is initially unknown. What transport and application-layer protocols besides HTTP are neede?
[00:22]<yzrmynx>needed*
[00:22]<yrdoul>tcp/udp and dns
[00:22]<yzrmynx>iam8up: I don't think thats all, cuz I got it wrong :(
[00:23]<yrdoul>Iradieh - start wireshark, clear dns cache, wget something, look
[00:23]<szzvzg>likely udp not tcp
[00:23]<yrdoul>tcp for http and udp for dns
[00:23]<szzvzg>ooh
[00:23]<szzvzg>i was thinking dns only =)
[00:23]<yrdoul>dns is udp (for this case)
[00:23]<yzrmynx>iam8up: cool, does wireshark work on a mac?
[00:24]<bfun_ian>tcp is almost only used for zone transfers
[00:24]<yzrmynx>iam8up: that is MAC OSX :)
[00:24]<bfun_ian>a regular query is not large enough
[00:24]<yrdoul>uhh the newer mac i would guess so?
[00:24]<szzvzg>yeah not for an A record.
[00:24]<rdyxry>Yep
[00:24]<yzrmynx>Oh yeah we have x11
[00:24]<yrdoul>i know it works on *nix x86 so i wouldn't dou ttheres a package for it
[00:24]<rdyxry>Got MacPorts?
[00:24]<yrdoul>Iradieh - you could just use tcpdump, i strongly advise using wireshark for analyzing though
[00:24]<yzrmynx>nein waiting for the new macports, this version doesnt work and instead of fixing it they are waiting for the new version release
[00:25]<yrdoul>also..i came across this a LONG time ago - certain types of dns queries on a windows dns server wouldn't get through a cisco router because of something (size? i can't remember..)
[00:25]<yrdoul>there was a registry change needed for the windows dns server to fix the problem
[00:25]<szzvzg>mtu ?
[00:28]<yzrmynx>iam8up: well I am gonna do the wireshark thingie, but how do I clear teh DNS cache on a mac?
[00:28]<yzrmynx>the*
[00:28]<yrdoul>*shrug*
[00:29]<bfun_ian>Iradieh: restart the name cache daemon
[00:29]<szzvzg>nscd
[00:29]<yrdoul>uh /etc/init.d/nscd restart ?
[00:29]<yrdoul>i hate mac with a passion
[00:29]<yrdoul>so i'm the last one to ask about mac specific stuff
[00:30]<yzrmynx>iam8up: sorry =)
[00:30]<yzrmynx>thanks for the help man
[00:30]<szzvzg>killall -s HUP nscd
[00:30]<yzrmynx>Killing is the last thing I want to do
[00:30]<yzrmynx>Blue_Ice: do you know how to do that, you got a mac or just guessing?
[00:30]<yzrmynx>I tried googling
[00:30]<bfun_ian>nah, you don't have a rc.d / init.d
[00:30]<szzvzg>killing?
[00:30]<bfun_ian>it's something with lookupd
[00:30]<yzrmynx>Nvm I found
[00:30]<szzvzg>it's just sending a hangup signal to nscd
[00:30]<szzvzg>restarts it
[00:31]<yzrmynx>What does deprecated mean?
[00:31]<bfun_ian>dscacheutil -flushcache
[00:31]<yzrmynx>dscacheutil -flushcache
[00:31]<yzrmynx>haha I found it as well :)
[00:31]<szzvzg>what they said
[00:31]<rlraxne>dscacheutil -flushcache
[00:31]<yzrmynx>What does deprecated mean?
[00:31]<yzrmynx>English isnt my native language...
[00:31]<rlraxne>Iradieh: "old, not to be used"
[00:31]<yzrmynx>Apachez: Yeah I guessed so but just wanted to make sure =) thanks guys
[00:32]<yzrmynx>Gonna get wireshark going and do as you said iam8up thanks for the help man
[00:32]<rlraxne>a deprecated function is a function which no longer should be used, often there is a replacement function in place
[00:32]<yrdoul>Iradieh - np
[00:32]<yzrmynx>A pain in the ass, I said UDP and DNS but it was wrong :/
[00:32]<rlraxne>in cisco there is "vlan database" which is deprecated
[00:32]<bfun_ian>depending on the IOS version :-)
[00:32]<yzrmynx>hehe :D
[00:32]<rlraxne>vlans should be nowadays be configed through "conf t" and not through "vlan database"
[00:32]<yzrmynx>I never got my CCNA ceritifcate... I just got CCNA 1-4 :(
[00:32]<yzrmynx>Lazyness.. I had the chance, and for free as well :(
[00:33]<yzrmynx>School payed it all
[00:36]<bfun_ian>Iradieh: you could also just create a logging "allow" rule for you ip-address on the gateway router, in stead of sniffing on your PC
[00:39]<yzrmynx>Blue_Ice: I got a crappy netgear router
[00:39]<yzrmynx>iam8up: Alright, clear cache THEN sniff ?
[00:39]<yrdoul>yop
[00:40]<bfun_ian>:-)
[00:40]<yzrmynx>Blue_Ice: then do what, surf to random webpage?
[00:41]<bfun_ian>yep
[00:41]<yzrmynx>and what am I looking for?
[00:42]<yzrmynx>All I got was TCP
[00:43]<bfun_ian>tcp http, or tcp dns?
[00:43]<yzrmynx>just HTTP no DNS
[00:43]<yzrmynx>Should I put in a filter
[00:43]<yzrmynx>like TCP 80 and UDP 80 ?
[00:43]<bfun_ian>do you have a dns server configured? :-)
[00:43]<yzrmynx>nah
[00:43]<yzrmynx>I just surfed to google
[00:44]<yzrmynx>Blue_Ice: the question was Consider an HTTP client that wants to retrieve a Web document at a given URL. The IP address of the HTTP server is initially unknown. What transport and application-layer protocols besides HTTP are needed
[00:44]<bfun_ian>what is actually your issue, because so far you have only asked us what's needed for browsing, not what the problem is in surfing
[00:44]<yzrmynx>Blue_Ice: Sorry I thought You saw what I posted, forgive me, but ehm thats basicly the question
[00:44]<yzrmynx>I answered TCP and DNS...
[00:45]<yzrmynx>wich was wrong :(
[00:45]<bfun_ian>the answer is, the name lookup protocol you have defined on the PC
[00:45]<bfun_ian>could as wel be WINS for example
[00:45]<yzrmynx>Blue_Ice: but in that scenario
[00:46]<bfun_ian>the answer is surely not TCP and DNS. only DNS at best
[00:46]<yzrmynx>Blue_Ice: TCP for HTTP and UDP For DNS?
[00:46]<bfun_ian>is it a multiple choice question? can as wel be "domain" for example
[00:46]<yzrmynx>nope..
[00:47]<bfun_ian>TCP and UDP for DNS, it will nearly always go for UDP, but there is always a chance that it wants TCP
[00:47]<2funrrcn>when i exec 'show flash', it shows all files that was ever created, even the ones i deleted it. how to wipe out thoses 'deleted' entrees?
[00:47]<yzrmynx>and TCP for HTTP?
[00:47]<xdlj>yes http uses tcp
