    Switch no router

    I agree with you JackMDS to an extent. There are somethings you can do with smoothwal/ipcop/linux software router that you can't do with a cheap hardware router. Like stateful packet inspection, special "zones", vpn termination. But then again these type of services are not really needed for...

    Need advice on Linux OS to use !!!

    Linux is really stable compared to home versions of windows, windows can be stable if you don't play. That being said linux is a great unix flavour desktop replacement, thats free, stable and oh so configurable. BSD wins though for a unix flavour server with stability, there are uptime reports...

    Steel foam ?

    Wasn't that the stuff they were going to put on tanks, basically it can absorb a few direct hits before becoming useless, just another layer of armour really. I can't remember specifics though, I think metallic glass will be the better of the two...

    The worlds oil supply

    Calin - But at our current consumption of crude oil means that every peice of farmable would need to be used to grow the plants to fuel our cars, meaning we would have no where to live and no food to eat, we have to find something else...

    RAID1 vs Non RAID??

    there are other reasons to backup, what if both discs fail, what if there is a fire/flood/other natural disaster, I personally don't have any raid yet, I gotta clear the space first, but I do make backups to dvdrw's and store them offsite.

    Question about Exchange

    yeah MS recommend you don't have your domain controllers exposed to the internet, but most small business I know can only afford one server, so it usually does it all, mail, web, terminal services, ad, etc.

    Need to have 5 computers on a 4 port router

    ah then we are saying the same thing... a mesh design or having big fat uplinks is always good. Mesh= switch 1 is connected to switch 2 and 3, and 3 is connected to 1 and 2, if each port is only 100mb this provides 200mb for inter-switch communication, not really the best but every little bit...

    Home Network setup

    An ethernet hub/switch has rj45 ports in it, so the cable that plugs in has to have an rj45 plug on it. The "hub" as they call it is actually a simple 8-port patch panel, up the top is the equivelent of a punchdown, you will still need a punchdown tool, and that is pretty expensive for an 8port...

    what network hardware do you like?

    the cover has nothing to do with how good/robust etc it is, just with netgears, the plastic ones tend to be made in china, and are of average quality, hence the yum-cha nickname, the metal ones are usually made in japan if I remember rightly and are of better quality, I have seen the plastic...

    Home Network setup

    it is very easy, cat5 is made for rj45, just gotta get the pairs setup etc, need a crimping tool, and a bit of practice, takes me about 5minutes for a network cable with the wiring diagram infront of me, but I know a guy who can do them in about a minute, from his head. If you are laying a run...

    how to make persistent VPN tunnel between 2 firewalls

    Forgot the software router root(pun intended), not a bad idea if you have the hardware lying around, cheap to do, a lot of configurability, matches the high-end stuff in features, not nessesarily as stable, but meh. Look at snapgear if you want a hybrid of these two, they make routers with...

    Home Network setup

    Ellisz - I am confused at what you want to do, if you are asking can telephony and network be run over the same cat5, then yes you can with a little hacking, as 100mb only uses 4 of the 8 wires, I had to make a could of cables to split this off for a customer. It is not the best solution though...

    what network hardware do you like?

    I have used and tested a heap of brands. I stick with/recomend Netgear (non-yum-cha, ie non plastic crap), Linksys, some D-Link (you can be unlucky with these guys), Cisco(except I can't afford it) and an Australian brand Alloy(make decent stuff cheap for locals). For firewalls, snapgear(cheap)...

    The worlds oil supply

    Another point on the Alcohol fueled cars, Ethanol/Methanol is already used here in Australia at some petrol stations as it is cheaper than petrol, they are only allowed to put in a max of 20% however, but this supposedly has no adverse effects on the cars, and it is all grown locally here. There...

    The worlds oil supply

    A Couple points, solar is actually an answer, but at present the cells requre oil to make. There is a house here in Sydney that runs entirely on solar(there roof is covered with panels), on grid, meaning they put power back into the grid during the day, and take it out at night, they actually...

    New military weapon that breaks the bones of everyone on a battlefield?

    The decibel levels on this kind of weapon would have to be so high the power required would probably be as much as is released in a nuclear bomb, and it would kill everything and destroy objects close to the blast, and there would be a zone where it would probably just disorientate etc. You...

    bacteria based computers?

    Yeah could you imagine if someone wrote a real virus on this... and there are some smart hackers out there, be very interesting, we are going to see simlar issues with augmentation, ie integration of cell phone, pc into a human body, this will be cool, make a backup of your memory etc, browse...

    We know matter can be converted into energy. Can energy be converted into matter?

    Yeah I know the only thing that will ever come close to 100% energy extraction effeciency is anti-matter/matter reactions, if this is ever done, we will have lots of energy. But there is some matter loss in Fussion and Fission, both end up with weight lost at the end.

    We know matter can be converted into energy. Can energy be converted into matter?

    I can't believe no one brought up the big bang Theory, the whole universes matter was pre-big bang a ball of pure energy, it expanded according to the theory to about the size of a grapefruit about 10 1000ths of a second before the big bang, cooled slightly, blah blah, exploded, matter and...

    how to make persistent VPN tunnel between 2 firewalls

    cisco pix handle this fairly well, all-be-it expensively, there are some yum-cha routers that do it however, but you are better off having the same router at each end

    Home Network setup

    Patch Panels are really useful, but you don't really need them, but they are pretty cheap and you can get the punch down tools pretty cheap too. The only reason I would go patch panel is if you were going to send telephony through the cat5, which is what I would do :P

    NAS hardware recommendations

    ah another advantage of a roll-your-own aproach, multiple drives, hot swappable, and multiple gigabit ethernet if needed, really though in most cases 100mb is enough.

    Need to have 5 computers on a 4 port router

    I didn't think it worked like that, I thought that the link between the two switches becomes a bottleneck, unelss you have GBIC connections between the two and only ten 100mb computers of the switch. Basically my understanding is that a switch can handle one port running at 100 while another...

    NAS hardware recommendations

    I set up a 1tb arrary for a client, with an old dual celeron 300 motherbaord and a couple of cheap pci sata controllers, all up around AU$2000, about US$1200, it runs raid 5, and has a dvd burner for their important stuff to be burnt too. SOrry but until you can show me a NAS that has 1tb in...

    Daft theory, but *could* it work?

    It also depends on your isp, I managed to get two links going once when I worked for the isp I was connecting too, it wasn't that fast really, yeah I could download at 10K/s which back then was awesome, but yeah cable/dsl/wireless will end up being cheaper now-a-days, and latency will be lower...

    NAS hardware recommendations

    Umm yeah all good ideas, expensive and somewhat troublesome, but still good :P USB drive, expensive, and innefficient. NAS, expensive and not as easy to upgrade it or multi-task it. My suggestion, build a pc to be a file server, if it is just going to be a file server you can get away with a...

    Wireless to Existing Wired LAN Problem

    I can't think of any reason you should add the router to that exclusion, though I have my exclusions set to for example 192.168.0-192.168.0.255 Just becuase I have friends occasionally connecting to my network. But if you have wireless, best to leave it as few addresses as possible if the...

    Wireless to Existing Wired LAN Problem

    Leave the windows firewall off, and add an exclusion or simlar to the norton firewall, to exclude your local networks ip range, this should allow sharing etc.

    Yeah about 90% of wardrivers I know won't bother with a network that even has wep64 activated, maybe if mac address filtering is activated and the ssid looks interesting they will have a look, but most that have tried to get into my network have given up (according to the logs anyway) once they...

    Wireless to Existing Wired LAN Problem

    it could have something to do with wireless if he/she has the ap directly connected to a pc instead of too the router/switch.

    I finnally have cable..yeah!!!

    speedguide.net has some tweaks yu can try, but really go to bandwidthplace.com/speedtest and do the test if it is close enough to your speed (and so is a donwload from a quick site like download.com) then don't worry about anything.

    intro to networking question

    The switch or the router can check the subnet mask, really depends, are you running seperate masks on each switch or one across the whole lan? Subnetting really isnt my strong suit however, but I am pretty sure it is done at the switch and at the router, for example an internet/extranet bound...

    Wireless to Existing Wired LAN Problem

    so the ap is connected to the router? What operating systems on all pc's, I assume win2k/xp you should just need to turn on simple file sharing on the laptop. Make sure netbios is on, on the laptop. Try pinging the other pc's from the laptop via there computer name and via there ip, post the...

    Some wireless connection questions
