similar to: Linux HA may not be the best choice in your situation. High Availability using 2 sites

In a nutshell and very first of all, you need at least 2 internet connections. Those ISP must be willing to setup BGP peering between your routers and theirs. Once that agreement has been made, you need to get their AS Numbers and submit the ASN request located on ARIN's website (http://www.arin.net). After some paperwork and money exchanges, ARIN assigns you an AS number. At that point,

We currently have a backup site at a different location to our main site. This backup site mirrors (as closely as possible) our main services, particularly web serving. Is there a way to have the backup site act as a failover for the main site using something like Linux-HA? They are on seperate internet connections with different IP ranges. Thanks -- Tim Edwards

One final consideration I forgot to mention, make sure you have a beefy router. Depending on your BGP configurations, if you want to receive all routes from the internet, that can seriously bog down a low end router. I'm not saying you can't get by with a low-end router, just make sure your router can handle the results of your BGP configs. --Todd -----Original Message----- From:

Hi everybody. I'm looking for the way to increase the depth value in 0.01 for each index group. Easier to explain with this example: >my_data=read.table("clipboard", header=TRUE) Depth s_name index 3852 Site_1 144 3852 Site_1 144 3852 Site_1 144 3852 site_A 145 3852 site_A 145 3852 site_A 145 3852 site_A 145 3852 site_B 147 3852 site_B 147 3852 site_B 147 3852 site_B 147 54962

Hi, I plan to implement a redundant Internet connection using BGP on 2 different Linux Routers. The routing daemon software I will be using is Zebra (zebra.org). I''m wondering if I should have my Linux firewall behind the 2 BGP routers, or could I keep the shorewall on both BGP routers? Has anyone had any experience with this? Any help is much appreciated. Thanks, Sam

Refering to pppoe i have next problem : I asked my isp if i can buy a class of real ip`s to be routed by them. They said elegantly it can`t be done . I want opinions . I am using an ADSL connection through a Speedtouch 510 configured in bridge. About Bgp : i asked someone if i can peer 2 different locations on 2 different ip`s using private asn number and he said yes , and what i don`t

Hello! I have trouble with multipath routing. Those options are enabled in kernel: [*] IP: policy routing [*] IP: equal cost multipath [*] IP: equal cost multipath with caching support (EXPERIMENTAL) <*> MULTIPATH: round robin algorithm But issuing: ip r a 1.2.3.0/23 scope global equalize nexthop via 80.245.176.11 \ dev eth0 weight 1 nexthop via 80.245.176.13 dev eth0

What I would like to do is have two identical * servers which accept registrations of sip extensions 4000-4999. If I define a rrDNS or LinuxHA then I should have load-balanced registrations. However, say ext. 4001 is registered on *1 and 4002 is registered on *2, if 4001 tries to call 4002 then I would like to do something like: - lookup 4002 on *1, try to establish a call if it's

Before I start, I don''t want to do ECMP or simple bonding ... I have multiple Internet connections available to multiple boxes on one of my networks. Box A connects to ISPs 1, 2 and 3 Box B connects to ISPs 1 and 4 Boxes A and B are both connected to each other and the rest of the network. 1) I would like to set up some dynamic routing in such a way that any given outgoing packet from

Hi, I''ve setup quagga on a shorewall firewall server. The only purpose for this is to use BGP to connect to a "peering platform" supplied by our data centre supplier. There are some very large ISP''s (and other various providers including google) on this peering platform and connecting to it will speed up access to/from our services and hosted servers. The physical

I am setting up 2 Vyatta routers that will serve as redundant failover core routers out to the backbone of our ISP. They will be serving for routing between other branches and the ISP and bandwidth management. I am trying to differentiate between the plethora of information about having redundant, automatic failover routers and pretty much decided on VRRP for the IP address failover mechanism. I

I''m being cast headlong into unfamiliar waters here, and being desperate for some air, thought I''d come here for some help. :) Anyway, my employer is going through some whiplash-inducing growth spurts, and as a result, the simple "Internet T-1 -> Linux Firewall/NAT -> LAN" setup just isn''t going to cut it anymore. First, we''re bringing in 2

hi all, i have been able to find only a trickle of information concerning possible strategies for a 2 adsl setup using two different isp''s. has anyone had experience in the usa or elsewhere working with their providers to carry bgp tables, or would you recommend/implement a round-robin arrangement? how ? :-) yours sincerely christopher cuse, rhce/ccna ccuse@tiscali.fr redhat 8.0

I am planning to replace our cisco 7200 core router with Linux. We currently serve around 1500 (3/4 DSL - different router) customers with probably half of them being concurrent at any given time. We have a fiber network and customers currently aren''t managed as far as how much bandwidth they can use at anytime. Therefore I have constructed a working tc qdisc Linux router as a test. It

I think RR DNS is the only viable solution under these circumstances. If you can cope with the fact that failovers won't be seamless, I don't think there's anything wrong with that though.

Hi list, I''m trying to setup a Linux box with a complicated source routing and could use a hand from you. The box has 4 NICs and lots of VLANs attached. It is a firewall and router in the following scenario: (obs: IP addresses have being changed for security purposes) - eth0 holds the default route (GW: 200.1.0.1, Firewall: 200.1.0.2); - The box is routing and sometimes source

Currently the only two targets that disable CFI are Hexagon and powerpc targeting BGP. Is that still correct? The current integrated assembler is working for PPC, no? For Hexagon, it has been disabled since the initial checkin. There is still no support for cfi? Thanks, Rafael

Hi, we have set up a small project in a school the following way: SITE_A(4 port analog to ip g729)------ADSL_ISP1-------ISP2--------Asterisk-----PSTN Site A has 1 Megabit of bandwith (up 512kilobit down 1 megabit) The asterisk box gets internet service via a wireless antenna. 1 Mbit of up/down bandwith Comments: So far, this means that I will need licenses for the 729. asterisk only supports 20ms
