Hi! I have many problems getting this thing to work. There''s a host with two network interfaces, where there are two routers to Internet in two separated networks. The host uses multihop routing for deciding to which router send the packets... but the routing decision is wrong made. Some packets with source address of one NIC, go to other network. I have a host with three NICs in it:

As I''ve read in http://gnumonks.org/papers/netfilter-lk2000/presentation.html, there''s said about the "nat" netfilter table: "This table is different from the ''filter'' table, in that only the first packet of a new connection will traverse the table. The result of this traversal is then applied to all future packets of the same connection." I

Hi! In our students'' hostel we have 6 DSL lines (dialups to different providers); we have set up a linux box (currently running 2.6.11-rc2-mm2, but the problem described hereafter also applies to previous 2.6-series kernels) with help from http://lartc.org/howto/lartc.rpdb.multiple-links.html#AEN298 Our Setup looks like this: 10.0.0.0/8 10.70.255.1 +----------+ +-----------+ |

Hi all, i''m new at LARTC, and after reading the docs I found no solution to my problem ... On one side I have eth0 conected to the LAN, on the other side I have eth1 conected to a switch and to 3 DSL routers with 3 diferent providers, and also eth2 conected to a cisco 2600 conected to a LDMS line. I have readed the larct docs about multihomed conections to internet, but I''m

Hi! I get this strange behaviour... I don''t know how some packets get into wrong rules. My rules are those: 0: from all lookup local 50: from all lookup main 201: from 192.168.17.0/28 lookup 201 202: from 192.168.16.0/28 lookup 202 222: from all lookup 222 32766: from all lookup main 32767: from all lookup default Table main has: 192.168.17.0/28 dev eth2

Why does rsync believe it knows more about the use of the token to the left of the colon than the program which will be used as the remote connection? I have a script called sshto with accepts targets like this: host1!host2!host3 and constructs the requisite ssh ProxyCommand options to do a multihop ssh to host3 to run a command. Very useful if connecting to firewalled nonroutable hosts or to

(2nd attempt, the mailing list is still bouncing some gmail SMTP servers because of the multihop DSBL.) Over the weekend I installed CentOS 5 on my hp pavilion ze5300. The graphical install went just fine, and everything (except wireless, haven't worked on that yet) seems to be working. However, on boot, the text console comes up. If I hit Alt-F7 manually, I'm switched to the

hello, I would like implement an academic theory of TCP traffic control gateway for wireless multihop environments. The main part is an dynamic pacing witch suffers from the RTT and hops in the wireless domain. With shell-scripts or how ever I can get my information for the actually pacing-time for an TCP-stream - the time can be chance over established TCP-session - so it''s be a

Hi, I'm having a small problem when using ProxyCommand and ExitOnForwardFailure in combination with OpenSSH 5.1 under Ubuntu 8.04. In order to enable multihop scp and port forwarding, I have enabled automatic public key authenticated tunneling from hostA to hostC via hostB using ProxyCommand in my private .ssh/config file on hostA. <end of .ssh/config>: host hostB user X hostC

Hello everyone I just found out this great tool. I need to use it to get access to DSBL zones. in their website it says Can I run my own DSBL DNS secondary? DSBL provides direct rsync access to our zones. To retrieve one of the zones, install rsync and run the following command: rsync -t rsync.dsbl.org::dsbl/<file> . where <file> is one of: rbldns-list.dsbl.org

Hi! (I sent other mails some time ago, about not-using the Julian''s patches). When I try the configuration from Nano.txt, having the Julian''s patches applied, only the first ''hop'' of the routing table "222" is used (according to tables shown in Nano.txt). I saw that this question was asked some time ago, with no answer. Maybe someone can tell me the

Hello, I''m trying to achieve the following. 2 ISP''s and 1 LAN with failover. So, when 1 internet connection fails the other need to take over. I''m aware of the restrictions. The current sessions are lost. I did this before, one and a half year ago or something. But at that router wasn''t failover. Now i''ve read the nano howto and followed it.

Hi I have an hp1220c printer I'm having problems with also. Which patches are you referring to and where can I get them?

That is what I thought, but just to clarify: I am using static dhcp hosts in the dhcpd.conf and our network config. is similar to this: 3 subnets 192.168.15.0/24 192.168.16.0/24 192.168.17.0/24 dhcpd.conf ### Global Settings for DHCP Services ### option domain-name="dom.com"; default-lease-time 900; max-lease-time 1800; ddns-update-style none; authoritative; allow bootp; allow

Hi I intent to use brctl to bridge two devices on linux box. One is eth0, the other is USB net which is recognized as usb0 by linux box. Then I run following command # ifconfig eth0 down # ifconfig usb0 down # brctt addbr ipbr # brctl addif ipbr eth0 # brctl addif ipbr usb0 # ifconfig eth0 up # ifconfig eth0 0.0.0.0 # ifconfig usb0 up # ifconfig usb0 0.0.0.0 # ifconfig ipv6 up

First let me say that I am not subscribed to the list, so please send me a copy of any replies. I have been using Shorewall for years as the firewall for my LAN. It has been awhile since I played Starcraft and hosted games. Back then I was using the 2.2 kernel with the loose_udp patch and no firewall. All worked fine. I stopped playing Starcraft a while back and later upgraded my kernel to 2.6

Hello, I wanted to try some multipath setup with Julian''s patches, and when rebooting on the newly patched kernel, without any multipath routes (only one interface up and one default gateway), my SSH connections to the server freeze after a few seconds. I tried with and without bridges (I sometimes have a bridge between a tap device and my eth0) with the same results. When I close

I''m using a 2.6.20-15-ubuntu (shipped with feisty) kernel with Julian''s patches applied and it''s my 3rd day with tc, ip, ifconfig and the rest ;). Got 2 ADSL uplinks. What I need is an ability to manually configure uplink usage, so nothing like bonding by default. Failover is meant to be provided via a shell script at the next step. Here is my config: == # no need for
