I have 4 NICs in my 10.04 server, 3 of which I have bonded. The bond itself is working fine -- I'm able to connect to and from the machine -- but whenever I try to ping out, I get duplicate replies. Google has, so far, yielded nothing of use.
I've included potentially relevant files:
/etc/network/interfaces
Code:
# The loopback network interface
auto lo
iface lo inet loopback
auto bond0
[Code]....
I've checked my /var/log dir and can't find anything.

But if I gave ping -I eth1 <IP> then I can ping.
I cannot install any package, so tell me solution which includes not installing any package.

View 1 Replies View RelatedI have an asus router running tomato firmware. Through the webGUI I have set up an openVPN server as per the tomato guides. I am using the network manager plug-in in ubuntu 10.04 to connect as a client to the tomato openVPN. All of my certificates seem to be set up and working correctly.
I am able to successfully connect to the openVPN server using the ubuntu client but after that I get nothing. On the client side I am unable to ping the router, any ip addresses inside my private network, the virtual network ip, and web browsing (client) no longer works.
Also, when connected I am unable to ping the client from the private network.

I'm bonding the two NICs on my FC10 server to create a bonded LAG between it and my Cisco Catalyst switch, but during kernel init, the system always give me a notice that "bond0 doesn't appear to exist" so it skips it.Once I log in, I can always open Network Manager and the bond0 interface goes from "Inactive" to "Active" and bond0 immediately works, and I can restart the appropriate network services and everything is fine. But any idea why this bonding wouldn't be initializing during boot up? The ports on the Cisco are configured for hard set speed and duplex and portfast is turned off on them.Is there a guide for best practices for creating LAGs (bonded interfaces) between FC10 and Cisco switches?
View 4 Replies View RelatedI have two machines on this network, one running Ubuntu and the other running Fedora.
When I'm using the Wireless network on the Ubuntu machine, I cannot ping the Fedora machine. Everything else works. I can browse the net fine.
If I switch over to the Wired Network then I can ping the other machine.
I don't understand why ping doesn't work only over the Wireless. I can ping the router so I'm guessing it's getting blocked by the router but I didn't block ICMP traffic.
I tried asking on IRC and they ran out of ideas too to find out where the problem is.
Ive got a problem on my server ....installed Debian 5 , Webmin and than syscp settung up syscp ready ....

Is that the bind9 maybe?
I have two servers that have been running link aggregation and VLAN trunking for years. I've installed larger drives in one and done a fresh minimal install. In spite of configuring as before the network will not come up. I did discover that a minimal install will not install vconfig which was causing one particular error when the VLANs tried to come up and this has been solved by installing vconfig. However, at this point the problem appears to be not bonding eth0 and eth1. /proc/net/bonding/bond0 indicates: "bond bond0 has no active aggregator"
If I put the old drives back in and boot the old OS everything starts up fine. I was even able to get it working with:
modprobe bonding
ip link set dev bond0 up
ifenslave bond0 eth0 eth1
service network restart
however, it does not survive a reboot. Is the a bug in the 2.6.18-194.11.4.el5PAE kernel or the network scripts? The the previous kernel I am running is 2.6.18-128.1.10.el5PAE For what its worth, these are the configurations:

I just installed my first EVER bind DNS server. I am running bind9 on Ubuntu 10.04. Everything seems to be working great except one thing: If I ping a host that I have set up in bind by its HOSTNAME the pings take 5-6 seconds to reply/print to the screen between each echo response. If I ping by the host's IP address, they echo back very quickly.
I have read that IPv6 can cause this, but I have disabled it in /etc/sysctl.conf and the problem still exists.
I know everyone says this can't be a DNS issue, but this never was an issue with dnsmasq (which i was using prior), and it doesn't make sense that the ping are ONLY slow when pinging by hostname and not IP.
Configs below:
Ping by hostname - there is a 5-6 second delay between each one of the responses:

Ping by IP - the responses come VERY quickly one after the other:

So, I have an Virtual Machine running CentOS 5.4. It sits behind a hardware firewall which also does NAT'ing. I've set up plenty of these, so I know for sure the firewall and NAT rules are set up correctly. From the host, I can ping anything in my subnet and the gateway. But I can't ping anything else beyond the gateway. I can perform DNS queries and when I try to ping, it finds the appropriate IP address.But from the outside, I can ping the PUBLIC address (It's a 1 public to 1 private address NAT, not 1 public to multiple private). I've tried it with IPTABLES on and off, with no change.

I am having problems with bond0 starting at boot on ubuntu server 9.10. After I do a restart I have to manually start the network with "ifup bond0". I have installed the built package (ifenslave-2.6_1.1.0-15ubuntu1_i386.deb (as indicated in Bug #482419)).
I have setup bonding for mode=6 with miimon=100 using eth0 and eth1 (both are Intel 10/100/1000 ports using an aic79xx network driver).
The contents of the aliases file are:

View 5 Replies View RelatedI have been googling for three days, and I though posting to a forum would be more helpful than throwing my box out the window.
[Code]...
I was able to bond eth1 and eth2 together as bond0, but I am having problems with setting up two gateways on bond0. I can set one (eg ISP1) and all the traffic always routes through that ISP. Thus defeating the purpose of bonding. eth1 and eth2 pull an ip just fine and were able to ping the internet before bonding. Originally, I set the bond0 ip to the same subnet at my internal network, but I read that in order to set up nat you need to have the adapters on two seperate subnets.
Every time I fix one issue with this scenario something else breaks. I have tried dozens of different configurations. I am relatively sure that it is just a routing table issue, but I was wondering if anyone could point me in the right direction.

I've got a server that has bond0 and bond1 setup. I'm documenting some things in case I need to failover and bring up my secondary server up as primary... I just need to know if simply creating the interface ifcfg-bond0:0 with a new IP address obviously of the crashed system,,, is all that needs done or do I need to load bond0:0 module in /etc/modules.conf also?

I have looked inside and out of KMail, and for the life of me, I cannot seem to find out how to make KMail maintain HTML formatting and keep the images when REPLYING to sender or FORWARDING an email to another or others. Does anyone know a tweak to make KMail Replies and forwards to stop convert everything to plain text and strip the images? I live in a family where we all share parody, etc. emails, and plain text rarely ever cuts it. I did not suffer such with Thunderbird.

Linux has duplicate address detection mechanism for IPv6 and nothing for IPv4 in kernel. At boot time, initscripts take care to check for the duplicate address but when an IP address is assigned using ifconfig or ip utility, no error is generated.
View 2 Replies View RelatedThis is more of a cosmetic issue than anything, I guess, but it's kind of annoying so I'm trying to understand the reasons for it.I currently have two computers running on my upstairs network.One is a Mac running OS X Snow Leopard (with Windows Sharing enabled and nothing else) and the other is now running Fedora (15).When I look under Browse Network in Nautilus, I see two icons for my Mac.One seems to point to my system via the IP address and the other via the short hostname. If they represented seperate network protocols, I could understand it but they're both representing SMB connections. So my question is WHY? I added the IP and hostname to Fedora's hosts file thinking it might "unify" the presentation here

This applies to my 2 opensuse PC's, my Windows PC is fine.I can ping a hostname, say "PC1" but I can not ping PC1.domain.local (even the host PC can not ping it's own FQDN). When I ping just the hostname the ping stats even list the FQDN.Onto the next issue, since all my PC's, have the domain prefix domain.local, my Synology can not. I can ping it's IP and that is it. I can resolve it's name with nmblookup just fine tho and that is what is killing me. How is this not resolving.Even weirder, I can browse to "Synology" in Network Servers under places on the slab.

What's the problem with these settings...
I am trying to get a Linux (Slackware 13.37) working in a Windows networking environment. The IT support for this organisation does not extend to Linux support, so I'm limited in what help I can get for this.
I'm trying to get to the point where I can get to the internet to download what I need on this Linux machine.
The situation is this (*fictitious addresses used) -My Linux machine uses a fixed IP address (10.100.150.21)
My Windows machine uses a DHCP assigned IP address (10.100.150.213)Both Linux and Windows machine are configured to access the gateway server (10.100.150.1)So, I can ping the Linux machine from the Windows machine and vice-versa.I can ping the gateway machine from the Windows machine.I can browse Windows Shares on the network via SMB from the Linux machine.I CANNOT ping the gateway machine from the Linux machine with the Destination Host Unreachable message being the error message.
For actual internet access I need to access a proxy server but since the Linux machine can't even ping the gateway server, it fails to ping the proxy.Now, I have been told the gateway is a HW based router and for Windows machine they use some software for authentication to connect to the network. This software isn't available for Linux, so that's why I've been told to use a fixed IP address.My experience of networking is pretty basic and most of the Linux setup is done via running Slackware's setup program.
