Hi All,
Sorry for being OT.
I recently saw some aggressive marketting of Powersurfer Broadband Internet connection in Kandivli (W). If anyone is using such connection from powersurfer, then plz let me know how are the services. Also plz let me know if it is possible to connect to the net on the Linux box also. They told me that there shud a LAN card on yr m/c. Now which LAN card shud I purchase keeping in mind the compatibility in Linux?
TIA,
Warm Regards, $ sonpal -kj
At the BSES demo center they show 80-100 KB read and stuffs like that, but my friend just took it a month back and he says the realist Avg speeds are about 8-10 KB. Well its good that u save on ur Tele cost & the speed are ok for an avg surfer, but having seen-n-heard crazy figures like 80-100KB, 10Kb may be a bit depressing.
I do not see any reason why it will not work on Linux box as it simply uses a LAN card, and simple TCP/IP settings like DHCP/HOST/DNS etc. I have used RH with intel, D-Link, NE2000, compex LAN cards and they work well.
ALso I have heard that Huges is comming up with Dish antenna based wireless Internet access by Aug end. and that too with reasonalble rates, may be u wanna wait for that, beore taking the plunge.
Let me know ur story...
Hope this helps. --Sandeep

Does this mean that my m/c will be just another m/c on their LAN and it will be online as long as the m/c is up? And if this is the case then I think I shud be able share the connection with my neighbour(s) also ;-) Any idea?

Hi, I read in the COMPUTERS magazine published by IEEE society that there is a raging debate in the world about the broadband access and the touted speed.
According to what I read (and what I recollect) is : broadband at a times can get slower than dialups. This is a fact. So if one is constantly experiencing 8-10KB/s it is possible in the future that he/she will be experiencing 1/2KBps if ALL the users in the area log on simultaneously.
Second question that jumps into my mind is that WHY PURCHASE CABLE MODEMS?? These cablewallahs are giving u access thr. LAN cards worht 900-700 rs. why go for 15000/- cable modem. Will the cable modem boost the speed. Can anybody throw light on this as I am very weak at fundamentals of networking.
thanx,

The BSES Telecom (Powersurfer) connection is also direct to LAN card using Cat5 cable. Installation costs are Rs. 5000 and you have to pay Rs. 990 monthly. I had applied for their connection 4 months but am yet to get it. This is due to the fact that there are only 3 subscribers at the moment in our colony. A connection requires a certain number of subscribers within a 100 metre radius (The limit of the Cat5 cable, IIRC). I expect the connection to be better than others, especially better than services offered via the cablewallahs since bandwidth is not shared.

Bandwidth is shared, If it wasn't, the Internet as we know it would not exist. At most it would be shared after the first peering point, but it is still shared. You will get better individual bandwidth the closer you go to the backbone. If you want better speeds upto the first peering point, get a switch instead of a hub. Witha hub, your have a worse situation than a cable modem, since the modem does not broadcast like a hub.

That is because all these systems use shared bandwidth, which is linearly distributed among users unless someone does traffic engineering.

Actually, the cable modem is the interface to the broadband CATV connection. The cable modem extracts the data off the CATV line and converts it into ethernet baseband mode, which can then be fed to a client's ethernet card. If instead you feed the output of a cable modem to a hub/ switch (directly if the operator has assigned enough addresses, or through a NAT/ proxy if not), then multiple people can access it.
This should not be a problem even using 10 MBPS ethernet, since the maximum limit of a cable modem connection is only about 6 - 8 MBPS. The reality is that most cable modem operators have back-end bandwidths of 2 MBPS (one E1 line of 2.048 MBPS) - at least, this is the information I got from the InCablenet guy. Divide this by 500 users, and you get (2*10^6/500) = 4 KBPS per user. This is not a lot of bandwidth. However, things are actually a little better than this, because there is the question of the duty cycle - not all users are logged on all the time, and not all of those logged on make access requests simultaneously. Hence, we can generally expect an average load factor of about 30%, so that you can expect a bandwidth of around 10 KBPS normally - unless a lot of people decide to get online simultaneously. Therefore, a 10 MBPS Ethernet connection can very well be shared among a number of people,with no deterioration in the bandwidth.

Krishnan

Hi, It seems from your explanation that one will need a cable modem only if multiple users are loggin on simultaneously. The advantage is not that of speed but avoiding more wiring connections. Is it that what u mean?

Actually, that is just one implication, and not the most important one either. You could connect a NAT box or proxy server to an Ethernet connection (maybe derived from a cable modem, maybe not), and get the same result.
The point I was trying to make was that installing a personal cable modem is no guarantee of speed. You are going to get speed only if there is suffucuent bandwidth available in the system.
Having said that, remember that you will always get more speed if you have a cable modem to yourself, rather than sharing it between several users.
There is also the question of security. If you're running off a shared Ethernet lan, unless you've secured your system properly, you're going to have possible security issues. I believe cable modem connections are rather more secure, but cannot confirm it since I have never used one.

Cable modem connections to your Pc are as safe as a dialup connection, i.e., not at all. You are vulnerable if you are running vulnerable servers.

Depends on their login client, if they have one. Check the archives for discussions on the Cyberoam client for pointers.

That depends on your budget. Linux supports all the common network cards out of the box. Best of breed will mean a 3 Com or Intel card, but those will be very expensive. For example, a 3 Com 3C509 card will cost you nearly 2K. Also, it is a 10/100 MBPS card, which you do not need to connect to the Net.
You can get much cheaper cards from D-Link, Surecom, Compex, etc. These cards are basically NE2000 PCI clones, and as such are technically inferior to the 3Com and other more expensive cards in areas like PIO vs. DMA, etc., but are very much Value for Money. I just bought a Surecom NE2000 PCI compatible LAN card for one of my home machines for just 525/-!
At those prices, these cards are sure hard to beat. They're well built and reliable cards too. Just make sure you specify a 10 MBPS card with a UTP port (not that you will get cards without UTP these days).
HTH,
Krishnan

AFAIK, yes. generally, you can expect PCI cards to be PNP. If you're getting one of the NE2000 PCI compatible cards, you can just fire up linuxconf as root, go into networking->clients, and set it up as eth0, with the driver set to ne2k-pci (the driver is ne2k-pci.o), so that even if there is some problem with autodetection, you can still set things up in a fairly easy way.

Krishnan, What do you mean by PNP in the context of PCI network cards? PNP - Plug And Play, was supposed to be a method for peripherals to get connected and start working without having to go through the hassles of restarting the machine.

Nope that is HotSwap and to date not available on any of the pc buses (dunno about PC104).
PNP was designed to avoid the decesion making about i/o addresses, interrupt and dma allotment. AFAIK they are supposed to have a small set of internal memory locations which can be queried for hardware info (the earliest pnp cards on isa used to have a serial eeprom with the config. Also the io address decoder is register programmable.

Hey, wasn't HotSwap used for the SCSI HDDs? BTW, what was MS advertising about PNP with winDOZE 95?

Definitely not. I've been told that Powersurfer uses Ethernet for the last mile. In that case, if you're using an unsecured Windows machine, you will be exporting your filesystem to the world. At the least, ensure that you use a good protection scheme such as Sygate Personal Firewall (look for it on download.com) to block critical ports such as 137-139 (Netbios), etc. so that you will have a reasonably secure machine. And remember, Windows is prone to all kinds of exploits, buffer overruns, et al. If you *have* to run Windows, I recommend a rather more secure system such as W2K (again properly secured, with all admin options locked down), Code Red notwithstanding - just apply the patch. :-(
You can do all this stuff a lot better - and more easily - if you're using a *NIX such as Linux or one of the BSD's.
