  1. OpenBSD's Puffy!
  2. A CCNA is incredibly basic, and you can't really do much with it. What it does give you is a foundation to go get other certs, or to understand certain elements of a network. If you have little to no networking experiance the CCNA course is a great intro. If you do have experiance it'll be a waste of time, but a good stepping stone to the CCNP/CCIP/CCISP level, which are very valuable certs.
  3. Lol, I don't have time to check but that sounds like a quote from a Cisco textbook . A switch is a multi-port bridge.... The router's that you would purchase in a staples/futureshop/bestbuy/etc have a four port switch, with one port of them that routes between stations connected to the four port switch, and the one routed port. You would normally connect your modem to this. These devices also usually have DHCP servers built in, meaning you can have your machines on the network automatically addressed. Overall, if you don't already have a router in your house, and you want to connect multiple computer either together or to the internet buy a router. If you have a router and need to add more ports buy a switch.
  4. Any firewall on any unix box can do this. It's just port address translation. Just use a firewall/box at a control point in the network, like an edge firewall, to translate the port for you.
  5. PXELinux... the computer operates you.
  6. Just make sure that when you're done learning all the Cisco stuff (I hesistate to use the term propeganda), go read TCP/IP illustrated, or The TCP Guide, or some other nonCisco book. The Cisco material is great, it's just slanted.
  7. When I get a spare machine I'll give it a shot, but then I need to get a KVM .
  8. I use OBSD on my two firewalls, and as my backup router. OBSD makes an absolutley amazing firewall/router OS due to PF, and included routing daemons (rip, ospf, and bgp). As a desktop it has a couple rough edges, and I didn't use it for too long, but its also running on three of my servers. It's rock solid and secure, however it's users aren't very vocal AFAIK. Check it out, you'll love it.
  9. Also they have to be unicast streams as multicast will not work on the interw3b.
  10. Watch the cartoon first, then read the article. Keep in mind that those special lanes are a good idea, but we shouldn't have to pay for them. QoS is a great idea, as long as it's fair QoS that doesn't choke certain traffic (BT). I think the networks should be smart, but what we don't need is smart networks designed by dumbasses (greedy telcos).
  11. Thats how ettercap/dsniff works. It's call arp spoofing. When a endstation sends a request for "who has <gateway>" you respond with "I do". Or you intentionally poison arp caches.
  12. Post the following: cat /etc/resolv.conf netstat -nr ifconfig -a and a ping to the default gateway
  13. The physical layer encoding of the byte stream is irrelevant (QAM). You're looking at half the equation. Yes we can multiplex multiple digital streams over the same set of analog frequencies, but the less frequenices used by cable means more available frequencies available for broadband, or other uses. What exaclty is your point here?
  14. Less analouge channels means more free frequencies to use for cable internet. They may not allocate it that way, but they could. In terms of what they should do and what they're going to do... they're already talking about moving from the current broadcast cablebox methods to multicast IPTV in some area's, and the FTC is already considering it. In Europe and some parts of Canada they're already doing it. In terms of Ellacova deployment, I know similar stuff from Sandvine Inc has been deployed by Shaw, Rogers, and in the U.S Time Warner.
  15. Bear in mind that I'm playing the devils advocate here..... but there already is something of a two tiered internet between carriers. Transit traffic through ISP's already gets prioritized based on the contracts they signed when they agreed to peer. All you'll see with a more formal two tiered internet is content providers will pay for faster connections, which could be a decent thing. What we're scared of is ISP's charging x dollars to institute QoS rules that prioritize one service over another, however is content providers peered directly with major carriers to provide faster service (decrease number of hops, and have direct connection to carriers) service could be improved. Although a QoS fee isn't being paid money would be exchanged as part of a peering agreement. For IPTV you'd see more of this as carriers would want a direct connection to the content they are providing.... Of course this is just one vision of a two tiered internet, but QoS is a good thing, low priority bulk transfer is a good thing. Please note I mean what I say, low priority, not to the point where you can't use Bit torrent as it's been so throttled, but it's only fair that web browsing, e-mail, and interactive sessions across an entire carrier network don't get slowed down due to bit torrent traffic. QoS and traffic shaping ensures that we can use things like VoIP and IPTV without serious issues. In terms of the CRTC and analog cable, I'm sorry but I'm all for freeing up the analog spectrum for faster cable broadband access. I want multicasted IPTV, and I don't care if I have to get a settop box for it. Less analog channels means faster cable internet, which means we don't have to pay tons of money to get FTTP. Lumi
