Re: [expert] cable modem question
Good question Todd... don't let people make sweeping comments which are not backed up... I have a LinkSys BEFSR41 (4port/1wan) which works quite well; never a problem. The other day, I upgraded the firmware. I was pleasantly surprised to find that unlike most TFTP upgradable boxes, this one can be uploaded via a TFTP client put rather than needing to install a TFTP server. BTW, the upgrade did not require me to touch the box physically, so it's great if you need to locate it remotely and still maintain its s/w. The latest software now has the ability to log all connections/attempts (see who's knocking at the door) to a log server (as well as maintain a short internal list). For details on setting up your Linux box to accept these log entries, visit my site at http://pfortin.com/Linux/LinkSys/ HTH, Pierre PS: I finally retired my Cisco router which used to be my firewall when I got the LinkSys (small, quiet, fast and reliable).

Re: [expert] cable modem question
I user all linksys stuff. I have 2 switched 10/100 hubs the wireless network access point a laptop using the wireless pcmcia nic. I am also using the Linksys cable/dsl router for a IDSL line. The piece I am having a hell of a time with is there 2 port print server. all I get out out of it is garbage excepth when I printt out the diagnostics from each port. then I get a nice printout. I called there tech support and all he could say is I have a corupted driver for both my hp500 and hp842c printers. Ive uninstalled everything for printing and reinstalled it no help. tis is on win98. The CUPS server wont even print through this thing. I finally hooked up a hp printserver and bam it worked first time. On Friday 02 November 2001 15:32, you wrote: just FWI as for the Linksys stuff ... I'd stay away.

So, my buddy says there is no way you can share the connection because how are you going to have the router know the computer name. My answer to him was DHCP. Dynamic Host Configuration Protocol.

Re: [expert] cable modem question
I've read sometime ago about the @home setup that gives a computer name and the changes needed in Linux to accept that config. Since I live in Brazil I hadn't that message archived, but you can find it in the web archives. About your friend setup: is possible to enable a network to use the same link. Set the first machine with the needed setup to work with at home. That same machine should be configured as a proxy for the network, so it should have two network cards, one with the ip address for @home, the other with an address for the house network. The other machines will use the first machine as a gateway. HTH orlando Todd Zashin wrote: I saw some communication regarding cable modems and I wanted to chime in with a question I have.

RE: [expert] cable modem question
Your friend is very confused. NAT devices (which Linux can do for you) hide the IP addresses names of your computers. In practice they don't actually hide it as much as they replace the connection so to speak. Packets going out to the internet are re-addressed so that they all appear to be coming and going to one authorized device. Even Winblow's Internet Connection Sharing does this (albeit POORLY!!!). So there is no need to authenticate more than one machine. @home works fine with this configuration and if you wanted to you could theoretically hook up your neighborhood to your one connection... But that's another matter. Many (now cheap) DSL and Cable modem router devices which support connection sharing or NAT will perform this function for you. Linux, however, does it right in that you can incorporate a lot of things which will act to cut down on needless bandwidth usage. Squid, DNS, Ipchains, etc. all act to increase the apparent speed by cutting down on the need to send actual traffic to your ISP. -JMS |-Original Message- |From: [EMAIL PROTECTED] |[mailto:[EMAIL PROTECTED]] On Behalf Of Todd Zashin |Sent: Friday, November 02, 2001 5:19 PM |To: [EMAIL PROTECTED] |Subject: [expert] cable modem question | | |I saw some communication regarding cable modems and I wanted |to chime in with a question I have.
