[19:06]<vz2ufzzzsz>when i think pat, i think the other direction
[19:06]<vz2ufzzzsz>i know its many to one, but i think going into the firewall, not out
[19:06]<vz2ufzzzsz>my bad
[19:07]<kz0gvr2>its all good tab
[19:07]<[mzvzyw]>dammit, no crashinfo file
[19:07]<vz2ufzzzsz>i need food
[19:08]<vz2ufzzzsz>lunch [Matrix] ?
[19:08]<[mzvzyw]>sure
[19:08]<vz2ufzzzsz>corner in 5 ?
[19:08]<[mzvzyw]>corner of sumter and lady?
[19:08]<vz2ufzzzsz>yeah
[19:08]<[mzvzyw]>yup, see ya there
[19:08]<vz2ufzzzsz>kk
[19:13]<da_sdyfnn|wjzc>:o
[19:13]<da_sdyfnn|wjzc>it worked
[19:13]<da_sdyfnn|wjzc>praise the lord :D
[19:13]<da_sdyfnn|wjzc>thanks bmcgahan, tabularasa
[19:13]<bsdrgdjg>im trying to figure out if i can fit a 28' trailer in my apt parking lot.
[19:14]<sazdn>safe answer: no
[19:14]<bsdrgdjg>yeah
[19:14]<bsdrgdjg>which means i have to let it goto a depot, and then unload my shit and load it onto a uhaul truck, then bring the uhaul into my parking lot
[19:15]<sazdn>or just go home
[19:16]<sazumam>Hey guys. This is trivial, but i'm studying for the BSCI and the spot I seem to get hung up on the most is text referring to NBMA. I understand the differences between the types of layer 2 protocols that can and can't broadcast (to a point, clarification would be useful as well), but the multiaccess part is kind of ambiguous to me. Does the multi access just refer to the fact that many nodes can communicate with that one node?
[19:19]<2drrrxrg>it means that many devices can be on the same logical network at the same time
[19:19]<2drrrxrg>i.e. full mesh, partial mesh, hub-and-spoke
[19:20]<sazumam>Ok, and what would be the opposite of that? Something to compare it to?
[19:20]<2drrrxrg>point to point
[19:20]<2drrrxrg>T1, T3, POS
[19:20]<sazdn>DIALUP
[19:21]<2drrrxrg>NBMA simply refers to X.25, Frame Relay, and ATM encapsulations
[19:21]<sazumam>I see
[19:21]<2drrrxrg>where there are virtual circuits that don't necessarily reflect the physical topology of the network
[19:21]<crvpyvn>bearing in mind that Frame Relay and ATM networks are most commonly used for point-to-point communication these days
[19:22]<2drrrxrg>true
[19:22]<sazdn>Frame relay doesnt have to be point to point
[19:22]<2drrrxrg>the main difference between NBMA and other medias is how layer 3 to layer 2 resolution occurs
[19:22]<2drrrxrg>the broadcast problem is related to layer 3 to layer 2 resolution
[19:22]<sazumam>So, NBMA point-to-multipoint would technically have multiple devices on the same logical network though, right? Unless I misunderstand multipoint?
[19:23]<2drrrxrg>i.e. what layer 3 address(es) reside on the other side of this layer 2 circuit
[19:23]<crvpyvn>skrumcd - basically 'NBMA' is a term that was invented to take the 'broadcast network' model of an Ethernet segment and add the caveat that actual broadcasts aren't possible. Multipoint Frame Relay is the canonical example.
[19:23]<2drrrxrg>where in Ethernet you can just broadcast an ARP request to find what layer 2 addresses are out there
[19:23]<2drrrxrg>but if you think of it in the context of ISDN
[19:24]<2drrrxrg>it's not feasible to call every single phone number to find out who's at the other end
[19:24]<sazumam>Ah
[19:24]<2drrrxrg>hence it is "non" broadcast
[19:24]<sazumam>Thats making it click well
[19:24]<da_sdyfnn|wjzc>bmcgahan, how would i setup the static map for pptp?
[19:24]<2drrrxrg>http://www.cisco.com/warp/public/471/pptp_faq.html
[20:23]<msxjv>love preparing for interviews
[20:24]<bsdrgdjg>Sam-I-Am: you around?
[20:24]<msxjv>lets think of all the shit I'm rusty on, and in the next hour get unrusty lol
[20:24]<srd-i-rd>BSDaemon: think so
[20:24]<bsdrgdjg>fuckin eh
[20:24]<bsdrgdjg>first of all, IRC support counts.
