Yesterday I posted a question, but I guess too much detail is provided that no one would bother to read, so I rephrase the question and hopefully some one may be willing to read. Sorry to spam. I am using TEQL on two computers, each with two network interfaces. The two eth0 are connected directly, and the two eth1 are connected via a gateway (a linux machine). The problem is that when I send

I have 2 machines running centos. each machine has 2 network cards. Box 1: eth1: T1 connection 74.X.X.X eth0: office connection 192.X.X.X Box 2: eth1: Cable modem 24.X.X.X eth0: office connection 192.X.X.X How do I issue a route command on each box so it will use eth0 as the shortest route between the two boxes??? Thanks, Jerry -------------------- On Box1 the route is: [root at mndemo ~]#

Hello folks, I have this really strange routing problem that no amount of googling and experimenting has been able to solve. Then again, I''m new to Xen and "advanced" networking, so I could be missing something very basic. Summary: an unprivileged domU with PCI frontend for a NIC is used as a router; icmp gets routed, but tcp/ip only partially. I''m using a

I'm having a bit of a problem getting tinc up and running between a pair of RedHat (one 6.0, the other 6.1) boxes. It's installed and configured to the point where they can connect, but I'm not seeing any traffic passing between the two systems. System A looks like - tinc.conf: # Sample tinc configuration. # Insert your own ip numbers instead of the placeholders, # and be sure to use

TEQL and Subnet problem I have a network topology shown below, and I am trying to use TEQL. P1, P2 and P3 are three linux machines, and each has two network cards. P2 and P3 are connected in two ways: (1) directed connection between P2.eth0 and P3.eth0; (2) connection via P1. P1 acts as the gateway. TEQL is installed on P2 and P3 to load-balance packet transmission by round-robin sending packets

Hi, I'm building a firewall/router on Centos. I'm using Shorewall but have currently stopped and cleared the firewall rules to isolate the routing problem. My firewall box has 5 interfaces in it but currently only two are involved in the problem. eth1: inet addr:192.168.1.224 Bcast:192.168.1.255 Mask:255.255.255.0 eth3: inet addr:192.168.202.1 Bcast:192.168.202.255

I just did a fresh install of centos 5.0 from cd, followed by yum update which installed 399 packages. No failures or errors that I can see. I have three nics in the box, but am only setting up one at the moment. The box can ping others in my network, but if I try ssh, telnet, ftp, etc I get this: [root at cm network-scripts]# ftp watchdog ftp: connect: No route to host ftp> [root at cm

I try to setup networking with a fresh CENTOS4.4 installation. Upto now I have 20 installations, most of them FC3/FC4 and RHEL3.

Hi, I am trying to fix a problem I have for about a week now. The environment is: --several independent servers with Centos5.4 on the latest patchlevel (example will be server2) All of them are working properly. --a machine with Xen installed to host some virtual machines (xenserver1) --domu servers on xenserver1 (crmserver1, winserver1) The whole network is connected with a Lancom router to a

I am unable to ping NE.TW.RKB.IP1 from an outside network. Other machines which do not have access or routes for NET.WOR.KA.0 respond just fine. How do I get it to respond on both NET.WOR.KA.0 and NE.TW.RKB.0 given all default traffic should go through NET.WOR.KA.1 unless it is in reply to traffic from NE.TW.RKB.1 or there is an outage.

TEQL and Subnet problem I have a network topology shown below, and I am trying to use TEQL. My problem is: When I ping to P3.teql0 from P2 ("[P2]# ping 16.119.144.66"), the traffic can never go from P2.eth1, and all traffic only goes to P1.eth0. What P2.eth1 (16.119.144.33) did is broadcasting an ARP asking for the MAC address of 16.119.144.66, although I have specified the route to

Situation: Running a simple UDP client/server program where the client on one domU on one computer sends echo packets to another domU on another computer, server sends echoes back. They do this on a specified port (will use any port between 5000-6000). This program works on non-Xen machines in various environments, Linux and Solaris. Program just hangs on the domUs. I believe I need help with

Last problem I had involved changing one character in my configuration scripts. Really easy once someone showed me what was wrong. Well I think this issue is just the same. The moment I used apt to install the Xen kernal and tools I lost internet connectivity. I have been managing because I can restore connectivity be deleting the bridge mpower@dodtsair:~$ sudo ifdown eth0

Hi, I been trying on ip rule fwmark and iptables MARK. I will show my testing in detail, but my ultimate question is why ONLY marking in Mangle OUTPUT tables works, but not others?

Greetings, I have a routing problem I am hoping can be solved. I have three networks. A Private network, and a dual network the private network connects too. The internal network talks through a gateway/router(linux redhat 7.2) that has a default route set that allows the internal network to talk to a computer on the external networks. The external network is a Redundant network scheme in
