    upstream charges to announce new ip blocks?

    Nothing wrong with announcing /24's. I'd like to know of a single provider who does block /24's. Maybe back in the day of 128mb core routers, but not now. It would lead to many inconsistency problems/complaints from customers and then you'd have to waste a network administrator's time trying...

    Opinions/Suggestions for this system config

    I'd opt for the Seagate 7200.8 300GB drive instead of the Maxtor. It costs a little bit more, but has an 8ms seek time instead of the Maxtor's high 9.3ms, plus it has a 5 year warranty. HD on newegg Also, I'd save some money and buy this ram instead of the Corsair XMS. The timings are...

    More than 2 PCI Express 16x slot motherboards?

    99% of video cards made in the past 2 years have been dual head. You could run a quad head non SLI setup with 2 regular PCI-E video card(6600's for cheap) and the DFI Lanparty UT NF4 Ultra-D. You'd even have a spare PCI-E 4x slot leftover for another card. Granted it wouldn't be 16x, but...

    The TRUTH about Prescott Overclocking...

    According to Intel you were giving the CPU .3 to .45 more volts than it's supposed to get. I'm suprised it ran at all, 3 weeks is superb for 33% more juice than it's rated for.

    Any way to get 2 dsl lines to my house on two phone lines, and tie them together to form 1?

    OpenBSD 3.3 with pf has basic load balancing techniques available, as well as a lot of other good stuff. You'll only see a speed improvement in http transfers mostly, but that's all most people seem to care about anyway.

    *4-17-2003 UDPATE* First Reviews Ready. Intel 865/875 (Springdale/Canterwood)

    CSA is only available with Intel 82547EI chipset network controllers, every other brand/chipset is PCI based. I think Intel doesn't do things like pci-x on consumer level boards is because it could cut into their server based chipset board sales.

    Multi-port NIC for server

    Intel 10/100 NIC's have been supported just fine under freebsd for years using the fxp driver. The 10/100/1000 intels use the em driver without problems as well.

    Traffic Shaping with Cisco 2500 and NAT

    Need advice on a LAN design project

    do not use hubs in this network. 10gige is very expensive, and comes in 1 port blade configurations right now. You'd want gige for the switch interconnects. Something like a cisco 3548xl(or 3524xl, depending on port requirements) per classroom, with a gige uplink to your collasped core...

    Gigabit Network

    If those new routers are configured correctly with nothing stupid like a duplex mismatch, they might be doing some qos. It's possible they're giving a lower priority to UDP traffic(hl, plus 99% of other online games). For instance, if someone made a TCP connection(web site hit, whatever), your...

    Gigabit Network

    What does your CPU utilization look like when the server is full and ping times start to rise? Gigabit would not drop latency for hl at all, even if your backbone network was all gige(which it isn't). Are just people on the university network playing, or is it internet people as well? If you...

    Gigabit Network

    high pings are usually a problem caused by wan links and the highly variable loads placed on them, nothing to do with your local switched network, which is probably not stressed to begin with. Each half-life player will use about 56k per second, not straining a 100meg uplink at all, even if...

    Cisco 6509 switch w/MSFC card vs a router?

    A MSFC/MSFC2 equipped 6500 series router will let you create logical vlan interfaces and assign IP's to these interfaces and do everything a 'router' can do. A MSFC is basically a npe-200 blade from the 7200 series, same CPU and everything. It is a 'layer 3 switch', 'routing switch' or...

    UDP datagram to port 1900 (from the gateway ip?)

    udp port 1900 is upnp, your router is probably upnp capable. You can disable it from the router if you're not using it, which you most likely aren't.

    Can someone explain why when you subnet you loose IPs?

    'gateway' ip's have nothing to do with subnetting. As far as the rules of subnetting goes, a 'gateway' ip is a host IP. Typically, the first useable IP in the subnet is used as the default gateway for the machines on that subnet. By using your example, a /30 would have: 192.168.0.0=network...

    How Cisco PIX work ???

    Take the switching test first, it's the easiest IMO. Then routing/remote access/support. The PIX OS is nothing like IOS as far as similar commands go. BTW, a PIX is overpriced junk and there is no need to 'study' one for CCNA/CCNP/CCIE routing/switching tests, none of them cover anything...

    Connection lags behind Boot

    I don't know what type of switches your school uses, but my guess is that the ports aren't port-fast'ed. Meaning they have to go through the whole 30-50 second spanning tree delay each time link is estabilshed before the port will start accepting traffic, DHCP, http, or otherwise. When windows...

    High End NAT Router Recommendation

    $15,000 might get you a memory upgrade straight from cisco for a gsr, not a 'base config'. Most if not all of those little soho routers don't support anything but a class C. A well configured unix system on a cheap pc will do all that you ask. What are you going to use the modem for?

    t1 IP address assignment

    The gateway of any IP host is never itself. In your case the gateway for the new host will be the ciscos ethernet port IP.

    t1 IP address assignment

    get a switch and plug the ethernet of the cisco into it, as well as the ethernet cable of the linksys/wan port into this switch. If I'm understanding your setup correctly, you can just add another host to this new switch with a wan ip and you'll be routing directly to the cisco.

    t1 IP address assignment

    linksys routers don't support more than 1 'wan' ip, which is what you're in need of. You'll need to put a host on the same switch/hub as the linksys wan port is, and assign it an ip out of your pool of 63.
