I want to check , whether ethernet bonding is done in a few linux boxes running on RHEL5 and freebsd . am using the following command to check them as well.

Is it ok , or is there any other place i need to look for ?
I instaled HPML350 G6 server. I would like to configure ethernet fail over. I got the script from my friend and configured and restarted the network services. I am getting the error message that ""Deprecated configure file /etc/modprobe.conf, all config files belonging to /etc/modprobe.d". System automatically assigning IP address also.
View 2 Replies View RelatedWe run redundant switches that two nic's on each server connect to. We also run bonding on our servers. Because we have two switches, we can't run lacp or anything. If a switch goes into a crashed state where it doesn't pass traffic but still provides link, bonding thinks the interface is still up and thus will still send traffic through it. Does anybody know a better way to configure the fail over of the interface? This would be a similar situation to somebody using a media converter.

I am currently investigating channel bonding for rhel5.5.Is there any way I can create one bond from nics on two different linux machines.They will be a cluster without any clustering software like beowulf or LVS.There will be a cluster interconnect through which they can communicate.Should I tweak the bonding module??

I have installed a LAMP server with Postfix as mail server. The scripts send email as user www-data using the mail server on the same machine.
However, the email got rejected by external mail servers (failed reverse DNS check) so I setup a mail server that meets all needed requirements.
Now I would like to use this second server instead of the mail server on the LAMP server. I found that this could be done with changing sendmail settings in php.ini (I think).
However I am not sure how that will go: www-data is no actual user on the new email server (which requires authentication before sending). Do I need to create a new user on the email server or change the settings in php.ini to match an existing user?
I'm using a linux server where nat server is running. Local user are connected from this server. So is there in tool that i can check that local user getting internet? or how can i check that a user connected from linux server using internet or where he visited?
View 1 Replies View RelatedI would like to implement something when a server is offline for whatever reason. For example. I got my own DNS servers and webservers. I would like it if the users goes to www.somedomain.com and the server it is actually on is down for maint. or For whatever not able to respond. What can be done so that if the server isn't able to be contacted that it can point to either a another server or the dns somehow can display a page stating who to contact to report a problem or to let them know its down for maint. And can goto a site to check the status or whatever.

I am running FC10, How to NIC bonding ..
View 1 Replies View RelatedI'm attempting to install a new OpenSUSE 11.2 system (64 bit) onto an Intel-based server. I'm having no success in bonding any of my network interfaces into a single 802.ad interface. I'm fairly certain the problem is not the switch as I'm using the same switch (Foundry FastIron SuperX) on which I have an older SLES10-based system that runs with 4 NIC ports bonded together in this fashion (as well as a number of W2K3 systems using SLA). I set up the older SLES10 box by editing /etc/sysconfig/network/ifcfg-blah files at the command-line as bonding was not supported by YAST in that version.
Now I understood, perhaps incorrectly, that YAST in OpenSUSE 11.2 permits bonding. So I bowed to the inevitable and from the GUI ran Yast->Network Settings and worked through all the tabs. I faithfully set up all the NIC ports to be switched off for bonding use then added a new Bond0 interface to which slave NIC ports are bonded. Default gateway was set to point to my router via the new Bond0 interface. I ensure that the firewall was off and that the relevant interfaces all pointed to the Firewall Disabled zone. After setting up as required, I rebooted the system and ran a test ping to a few addresses on the network. No joy. I checked the routing table via ip route then netstat -nr and then route all on its own. The routing tables looked as expected each time.
Getting down to first principals I ran ifconfig and again everything looked fine. I checked via modprobe -l bonding just in case there was something fundamental missing. Nope. I assumed that YAST hadn't worked as advertised and jumped online to grep for more info. Firstly I see that the HOWTO is out of date (Bonded Interfaces With Optional VLAN - openSUSE). I also noted that the bonding module option mode no longer supports numbers but upon looking at my ifcfg-bond0 file it contained mode=802.3ad rather than mode=4 so that wasn't it.
On comparison with SLES10 I did notice that config files of the ifcfg-eth-id: XX-XX-XX-XX-XX type were no longer used in Open SUSE 11.2 with only ifcfg-ethX config files. I examined those and also noted that the _nm_name and UNIQUE options were also no longer used. No need for lspci (or the Hardware control panel) when setting up bonding? Example of ifcfg-bond0 file contents (edited for brevity):

I've run across a few threads in the archived forums regarding nic bonding. I could be wrong but I imagine most of the people that are looking at bonding are probably really wanting what they would get out of creating a LAG between their Ubuntu Server and a managed switch capable of LACP trunks. If you have two NICS on your ubuntu server and want 2gps throughput & failover check out the page on creating a LAG. Obviously this requires your switch to be compatible though. [URL]...

View 9 Replies View RelatedI am basically wanting to use my Ubuntu 10.10 computer as a router. Note: Before you say just get a router please note that I am poor/cheap. I have two ethernet connections and one wireless connection on my netbook. I want to share the internet connection that is going into one of the ethernet cards through the other ethernet card and the wireless card.
DSL-->1sr Eth --> 2nd Eth (currently works)
DSL-->1sr Eth --> Wireless Card (Adhoc) <--(connects with limited connectivity AKA no internet)
The 2nd Ethernet card already has working internet, but when I connect to the Wireless card (through an Adhoc network), it cannot get an IP (I believe).
My laptop was working fine on wireless till the userinterface changed and it defaulted to ethernet and now it won't let me go back on wireless How do i disable ethernet?

2- steps to follow so that I configure bonding
I'm running 11.2 on a Dell PowerEdge1850. In the normal kernel, bonding is working just fine on the two ethernet ports. When I reboot into the Xen Kernel, I get the following error at boot:
FATAL: Error inserting bonding ... : Unknown symbol in module...
dmesg shows several Unknown symbols. In the end, the module is never loaded.
If I reconfigure the network in Xen to not use bonding, it works fine.

Is it possible to make Bonding?
I am seeing an issue on a few servers where it doesn't appear all NICs in the 802.3ad lag are all operating at the same level. A few of the servers have two bonds each with two NICs in each bond.I have two NFS servers that each has 1 bond with 3 NICs.All are RHEL5 x64 2.6.18.I think the reason why I see one interface dominating RX and another dominating TX is due to the xmit_hash_policy but there are three hosts that use this particular server for network traffic.That's 3 different physical mac addresses.The layer2 algorithm should be fine in that situation I would think.Would I just be better off with balance-rr?
