Connecting two Linux Desktops simultaneously to the Internet
Hello, I have two Linux Desktops at home (both running Fedora Core 9). I had connected both Desktop to a simple switch; also the ADSL bezeq router (BFOCUS 312+) is connected to the switch. One desktop has this ip address on eth0: 10.0.0.1 and on the second I configured 10.0.0.2 as the ip address on eth0. I can ping from 10.0.0.1 to 10.0.0.2 (and vice versa). When working in this topology,I am able to connect to the Internet from these both Desktops , in condition that the other one is not connected to the Internet (namely, "service network stop" was ran on the second machine, for example). However, if one machine is connected to the Internet, and I try "service network restart" on the second , I get an error (it cannot start the ppp interface on the machine where I run "service network restart"). My question is: is there a way to be able to be connected from these two Desktops simultaneously to the Internet ? I tried to add a second NIC on one machine, and configure that machine as a bridge, and set an IP address to that bridge, but than I could not connect it to the Internet. Is there some way to configure a bridge to achieve this goal ?

Re: Connecting two Linux Desktops simultaneously to the Internet
Rafi, You should configure your BFocus "modem" as a router for your network and apply NAT on all outgoing traffic. Take a look at post #14 in the following Israeli forum: http://www.fresh.co.il/vBulletin/showthread.php?t=1373 - Noam On Sat, Oct 4, 2008 at 12:49 PM, Rafi Gordon <[EMAIL PROTECTED]> wrote: > Hello, > > I have two Linux Desktops at home (both running Fedora Core 9). > I had connected both Desktop to a simple switch; also the ADSL bezeq > router (BFOCUS 312+) is connected to the switch. > One desktop has this ip address on eth0: 10.0.0.1 > and on the second I configured 10.0.0.2 as the ip address on eth0. > I can ping from 10.0.0.1 to 10.0.0.2 (and vice versa). > > When working in this topology,I am able to connect to the Internet > from these both Desktops , in condition that the other one is not > connected to the Internet (namely, "service network stop" was ran on > the second machine, for example). > However, if one machine is connected to the Internet, and I try > "service network restart" on > the second , I get an error (it cannot start the ppp interface on the > machine > where I run "service network restart"). > > My question is: is there a way to be able to be connected from these > two Desktops simultaneously to the Internet ? > > I tried to add a second NIC on one machine, and configure that machine > as a bridge, and set an IP address to that bridge, but than I could > not > connect it to the Internet. > > Is there some way to configure a bridge to achieve this goal ? > > Regards, > RG > > = > To unsubscribe, send mail to [EMAIL PROTECTED] with > the word "unsubscribe" in the message body, e.g., run the command > echo unsubscribe | mail [EMAIL PROTECTED] > >
Re: Connecting two Linux Desktops simultaneously to the Internet
Hi, 1) Thanks for the quick answer; I will try that. 2) Still I really wonder: can my goal be achieved when using the bezeq ADSL as it is, using configuring one of the desktops (which has 2 nics) to be a bridge? Does anybody have an idea ?

Cons: 1- the "front" linux will be exposed directly to the internet. 2- the "front" linux will have to be online all the time in order to provide service for the "back" linux. 3- More complicated security & network administration. Pros: 1- You're having realy heavy P2P traffic and require a strong machine (than ECI 312+) to handle the routing tables. (Yet, for my parents, the same ADSL hardware is sufficient for bittorrent traffic) 2- You want *real* control over every parameter in your router and the black box supplied by ECI does not provide that. Anyway, to your question, check out the "Linux IP Masquerade Howto" http://tldp.org/HOWTO/IP-Masquerade-HOWTO/ Fedora might have some bundled tools to assist you applying such a configuration, but this document will provide you with the basics on what needs to be done, why & how. - Noam

Hi, I tried to change the setting exactly according to the thread if frehs.co.il that you sent. Than I ran "ifdown eth0" and "ifup e I am able to ping www.google.com and other sites ; however, when I enter the URL of www.google.com or www.yent.co.il I am unable to get a page ; I must add that I did also disabled iptables on my desktop and it did not help (SElinux is diabled). When I am pointing my browser to an ip address of google (that I get from ping,namely , 66.249.91.17) I am able to reach www.google.com and clicking mail link, etc Any ideas what can be wrong here ? my /etc/resolv.conf says: ; generated by /sbin/dhclient-script nameserver 10.0.0.138 Regards, Rafi On Sat, Oct 4, 2008 at 1:30 PM, Noam Meltzer <[EMAIL PROTECTED]> wrote: > > > On Sat, Oct 4, 2008 at 1:18 PM, Rafi Gordon <[EMAIL PROTECTED]> wrote: >> >> 2) Still I really wonder: can my goal be achieved >> when using the bezeq ADSL as it is, using >> configuring one of the desktops (which has 2 nics) >> to be a bridge?

Re: Connecting two Linux Desktops simultaneously to the Internet
Hi, I now remember that I have observed a similar problem at my parents' place. The thing is that even though the bfocus 312+ claims to provide proxy DNS service, it has some major bugs in their implementation. I suggest that you set your Linux boxes to use your ISP's DNS servers directly and not the bfocus' DNS. If you prefer to still use DHCP provided by your bfocus, then you should override the DNS provided by the DHCP server according to the concept in the following article: http://kbase.redhat.com/faq/FAQ_45_12510.shtm Or you can drop the DHCP at all... - Noam On Sat, Oct 4, 2008 at 2:34 PM, Rafi Gordon <[EMAIL PROTECTED]> wrote: > Hi, > I tried to change the setting exactly according to the thread if > frehs.co.il that you > sent.

I'd use this thread to raise another issue (although it might have been nicer to start a new thread). This ECI 312+ is rather old - it's not sold (or given) anymore, as far as I know. But it runs Linux inside, and theoretically can do whatever you want - but as far as I could find out, ECI does not help you in any way - does not provide sources for their firmware, etc. Perhaps if enough people are interested (or at least determined ones), we can make them open up the device and have it as a nice young brother to the WRT54G (with only 2MB flash/8MB RAM).

If they were to open them up, it would create a demand for them again, and they probably have no way of fulfilling the demand, supplying spare parts or support for them, etc. As a cheap router, there are lots of them sold new in the 250 NIS range if you shop around, can any of them be opened up? Do any of them have a direct aDSL connection, or are they all ethernet on the WAN side? Geoff. -- Geoffrey S.

If that's the case, and they open up one of them, you get the software for all of them. Also, one can try and have external organizations that do such things, to help you politely ask them for it.

Re: Connecting two Linux Desktops simultaneously to the Internet
As much as I know, they contain MonteVista Linux. They where built by a subcontractor in Taiwan and when I asked ECI in Israel, they had no clue of what contractor and how can I get the sources. I know that MonteVista Israel also tried with no success so far. -- Ori Idan On Sun, Oct 5, 2008 at 8:19 AM, Yedidyah Bar-David < [EMAIL PROTECTED]> wrote: > On Sun, Oct 05, 2008 at 12:16:04AM +0300, Geoffrey S.
