similar to: [Bridge] tcp connection freezes when i dont ping the device first

hi list I have a strange problem here. Maybe it is normal behavior and i search within the wrong direction. Probably someone here can give me a hint. I have a device (rhel4 kernel 2.6.9) with 3 interfaces. 2 interfaces (eth0, eth2) are bridged together (br0) and the bridge device has an ip address assigned (192.168.11.15). Another interface (eth1) has assigned 10.7.0.10. So far so good.

hi i recently searched in the mailinglist archive and found similar problems, whose solutions helped very much, thank you. i have the following scenario: a firewall with one lan interface eth0 10.1.1.1/24 and two uplink interfaces eth1 10.2.2.1/24 eth2 10.3.3.1/24 each uplink interface does SNAT: iptables -t nat -I POSTROUTING -o eth1 -j SNAT --to-source 10.2.2.1 iptables -t nat -I POSTROUTING

Hello List, Are there any known issues in using the bridge-nf patch for kernel v2.4.28 against 2.4.29 or can it be used in production environments? is there already an adopted version of the patch for 2.4.29? Sorry if this question has already been answered elsewhere (I didn't find something useful on google, cvs and the list). Thanks, Marc

I have two multi-port bridges connected together with a lot of cables. Current setup is as follows: --------eth0------- | | [Bridge A] <-eth1-> [Bridge B] | | --------eth5------- Bridge A is root-bridge, and eth0 is set to lowest path-cost. Consequently on Bridge B interfaces eth1 and eth5 are in blocking state. However, when looking

Hi, i am testing two bridges by sending to it random packets using hping2. First i create a random-length file, then i send it a lot of time on the wire using this command: for ($i=0; $i<50000; $i++) { hping2 -q -c 1 -d $data_len -E random.file 10.0.0.10 } My problem is that some packets are lost. Here is my setup: PC1 (10.0.0.1) ===== BR1 --------- BR2 ===== PC2 (10.0.0.10)

Hi, I am very new to linux, sorry if my doubt is not valid, or i m asking some nonsense question.. Actually i want to use Linux as bridge. My setup is : Setup 1) i have two bridge (dlink) with 1 port connected to 1-1 windows PCs.I have configured ip addresses of both PC to same subnet.Now both the Pc are in same subnet and two bridges which are connected, so both r pinging to each other.

Hi, After adding my domain machine I realized that after 15 minutes it stopped pinging my domain. Interesting that this only happens in windows machines. I already checked the logs and did not notice anything. Does anyone have any light? Thanks

Hai, A copy of smb.conf is very handy, same as the running os. Follow these 2, and tell us what works and what not. https://wiki.samba.org/index.php/DNS_Administration#Testing_your_DNS_Server https://wiki.samba.org/index.php/Testing_the_DNS_Name_Resolution And do the following. Clear the windows event log, reboot, and ping the domain. Now wait 15 min, ping again to confirm its still not

Hello everyone, We have a physical server that hosts about 400 virtual machines. Each virtual machine has a TAP device connected to a Linux bridge. We tried to use Linux-KVM suggestions for QEMU networking according to this link https://www.linux-kvm.org/page/10G_NIC_performance:_VFIO_vs_virtio Unfortunately, we have a packet loss when pinging virtual machines' IP addresses. Pining the

Hello, I'm trying to use bridging in our servers and found a problem with dhcp. Some clients manage to get an IP from the server, using DHCPDISCOVER/DHCPREQUEST. However others use BOOTREQUEST and these don't seem to get an answer. The server sends a BOOTREPLY but the clients continue to send BOOTREQUEST for ever. There are also some (occasional) messages from the dhcp server like

I'm trying to bridge a mix of 802.1q tagged and untagged Ethernet frames through the new Ethernet over GRE functionality in kernel 2.6.28 The hosts handling the tunnel (192.168.200.6, 192.168.200.2) are connected together through with a simple cross cable through their eth1 interface. The switches are connected to their respective eth0 interface, which is bridged with their respective gretap

Hello, I manage a number of servers all running 2.4 (same problem exists with 2.6). My problem is that since a few bridge versions ago, I've had to modify net/bridge/br_fdb.c in the br_fdb_insert() function -- to get rid of the checks that produce this error: Jan 16 10:35:31 host15 kernel: tap_0: received packet with own address as source address Jan 16 10:35:33 host15 kernel: tap_0:

Hi, I recently upgraded the kernel in my Debian server from 2.4.22 to 2.6.9. This server acts as router and has an ethernet bridge (br0) that combines eth1 and eth2. Each of these two network cards is connected to one Windows PC. Since I booted kernel 2.6.9 it takes more than one minute for a client pc to receive its IP address when that one starts up. I noticed that the kernel messages (shown

Hi! As noted by Chris Rankin on a mail to netfilter-devel and to the linux-kernel mailing list (subject: 2.6.12: connection tracking broken?), there is a problem with the connection tracking of iptables when one of the interfaces is a bridge. On my tests here I have setup a connection between two machines using a real interface (eth0) and then the same setup using a bridge interface (br0) to
