Hello, I have a problem with the following setup, I hope you can help me. I have two internet gateways, one for LAN1 and the second for LAN2. +--------------+ GW1 more eth0| |eth4(SNAT) GW2 ---...routers...-----+ router +----------------- | | +---+------+---+ eth1|

I made a script to test if in a moultiple gateway setup all default connection are up, regardless of the fact that that gateway is the default gw. Suppose adsl1 and adsl2 are present, and all traffic goes by default to adsl1, and you want to test if adsl2 is ok. 1. I use mangles from iptables to mark icmp packets to some test machines 2. I set up a routing table for each adsl 3. I use

Hello, LARTC! I''ve been having troubles with load balance with ip + fwmark. I was wondering if these points are mandatory for this scheme to work: 1. Is there any problem if the linux gateway has a default gateway? Do I have to remove it? 2. In the scenario with 4 NICs, one routing table each, and another routing table doing load balance, Do the tables that imply routes that are being

Hello, I''m having a very strange problem concerning traceroute and routing and didn''t know if lartc or netfilter would be the correct choice for asking.

I have a gentoo 2.6.14 box with 4 nics, LAN/DMZ/PUB1/PUB2 LAN and DMZ have a 1918 /22 each, PUB1 and PUB2 have a /29 each of which 5 ips are assigned. Using the mangle table, I give all packets a mark (according to local policies) in the range 1-10. Using ip rule, i pass marks 1-5 through the pub1 route table, and marks 6-10 through the pub2 routing table. Using the nat table, I SNAT to one

I am running 2.4.20 with Julian Anastasov''s patches (routes-2.4.20-9.diff), iptables v1.2.6a, iproute2-ss010824 on Debian. I have set up our internal gateway to multihome 2 T1''s as described in http://www.linuxvirtualserver.org/~julian/nano.txt .

Hello r helpers! Below is the whole coding for my programme. Before proceed more further, let me explain for you. First of all, I need to compute trimmed mean. Till that step is ok. Then I need to compute ssdw which is sum of square deviation. If I do equal trimming at both tail of distribution that I chose, I will use the first ssd formulae which is "a". But if I am doing unequal

Hi! Some time ago I faced a problem in limiting traffic on host with multiple uplinks. Since all the stuff worked nice seemed that there will be no problems. But then I realized that P2P users are smart enough to bypass limits as sfq doesn''t give fair sharing in this case (thousands of connections from one user versus few from the other). I tried IMQ but it''s instability in my

Hi. So I have been having problems using scp to copy files between two of my machines, both of which are running OpenSSH 2.30p1 (though I've had the same problem with previous versions). It is basically as simple as the file not being transferred after authentication occurs. I can however use scp to copy files back and forth from another machine using a SSH Communications version

Hello guys, I am still in doubt about this kind of server. So my question is about the "prio" at routing tables like: I have 3 tables in /etc/iproute2/rt_tables: 201 201 202 202 222 222 In table 201 there is the rules about my internet link (frame relay) that comes into eth0. So I made this route into it: [root@ns2 iproute2]# ip route show table 201 default via
