Multiple network interface question

ok so i work for my college as a student worker in network operations. today they did a makeover on the dorm network and added in some traffic shaping. Instead of getting 8mb down im getting 1mb down. Well one of the admins went to lunch and had the new config still open on his computer so i shifted over and decided to take a look at this new ruleset. Im not sure why he did it like this but the traffic shaping is not done by a per port basis but by a per ip basis. Well i started thinking at this point and pulled out my old computer and installed arch on it to use as a download box for all my bittorrent needs, i have this box loaded up with 6 nics (5 pci and 1 onboard) each pulling their own ip, how can i get arch to bridge all 6 nics (or multiplex) so i can get atleast most of my bandwidth back.
Yes i asked them to exclude me from the trafficshaping but was told it wouldnt be fair to the other students

This might help: http://lartc.org/howto/lartc.rpdb.multiple-links.html

ACS 5.4 multiple network interfaces support

In ACS 5.4 release note, it says:
Multiple network interface connector support
ACS 5.4 supports up to four network interfaces: Ethernet 0, Ethernet 1, Ethernet 2, and Ethernet 3. ACS management functions use only the Ethernet 0 interface, but AAA protocols use all configured network interfaces. You must connect the ACS nodes in the distributed deployment only to the Ethernet 0 interface. Therefore, the syslog messages are sent and received at the log collector's Ethernet 0 interface. Data forwarding from one interface to another interface is prohibited to prevent potential security issues. The external identity stores are supported only on the Ethernet 0 interface. In ACS 5.4, multiple network interface connectors are also supported for proxies.
But in the CSACS 1121 Series Appliance Rear View section, it still says on Ethernet 0 is usable. All other interfaces are blocked.
I am confused. Can anyone clarify for me if we can use multiple network interface in ACS 5.4? What about management interface?
Thanks!

We configured 2 interfaces in past within testing enviornment and it worked. ACS 5.4 supports multiple network interfaces on the UCS platform, on a virtual machine and on the legacy ACS 5.x IBM/CAM hardware. The ACS management functions use the interface eth0 only and the AAA protocols use all available network interfaces.

Multiple network interface....

I have group (cloud) of systems and each system has two network interfaces. One interface is 172.17.0.0/19 and other is 192.168.x.x.
The 192.168.x.x network interface is dedicated to NFS (usually). So I want to configure that interface do not listen to inetd services and SSH. I want only RPC and Portmap services should be listening on that interface. And other interface (172.17.0.0/19) for normal services.
( Note: all system running Solaris 9)

Hello.
WHY do you want inetd not to listen on this interface?
I do not think that is possible with inetd. If you wish to prevent users to connect from another interface you must use the "tcpd" tool (on the companion CD). However inetd will listen on the interface; tcpd will just block incoming connections.

Role of multiple network interfaces

Hi,
I'm trying to setup a Mac Mini Server to act as a gateway and to offer various services from inside and outside of my office. For me this is some kind of test setup before I may look into getting a bigger machine for this job.
Because a gateway needs two ethernet interfaces I got an Apple USB-Ethernet adapter which technically works without problems. However since the USB-Ethernet is slower than the internal ethernet interface of the Mac Mini I want to connect the USB interface to the internet (fixed IP, DNS forward set, reverse in work) and the faster internal interface to my internal network.
The server is set up to make NAT but DHCP is done by another server. So the internal address is also manually set. Also there is an internal DNS Server I've setup the server to use it's own DNS service.
It took me some time to figure out how to make the USB interface (en2) the primary interface by turning off the internal interface (en0) during installation and adding it at a later time. So when I'm now doing a changeip -checkhostname I can see that my external address is my primary interface and my public hostname is correct.
However my biggest problem at the moment is that it seems as if all services are bound to the internal interface/network (en0) and I'm not able to access services like VPN, iChat or web from the internet or by using the public hostname.
Do I have to somehow tell all these services to explicitly bind to the external interface/address? Or is there no other way than to use en0 as the external interface in my configuration?
Thanks,
Alex

Please search for existing discussions of establishing static IP routes; this stuff can and does work, but requires manual set-up. IP selects a primary NIC in the absence of a known route regardless of the NIC the message arrived on, which means the Mac box doesn't work like you'd expect without some help. [Here's one discussion|http://discussions.apple.com/message.jspa?messageID=5697532], and there are others.
Mac boxes don't make particularly easy nor effective nor efficient nor economical firewalls in my experience, and this is inherent in the design differences between a Mac and a dedicated firewall. External firewalls are an added expense for a small network, but (in my experience) tend to have advantages over using a Mac box doubling as a firewall.
Given the number of folks that try this particular configuration, it would be useful for Apple to provide some guidance and some tools here to set up the static routes and to operate the Mac as a router (in some future release of Mac OS X Server after Snow Leopard Server 10.6); you're going to be using the bash shell to get this stuff going.

Multiple Network Card Question

I've got a Pc which has both a ethernet card and a wireless dongle used at different times.
In the setup for the 2Wire.com router I get the PC name listed twice ,once for each network card, understanable in a way I suppose as they have different identities on the LAN. But, when I'm making settings for the PC in the setup, I don't know which one I'm making the setting for - the PC name is just listed. How should I be doing this?

Don't worry, I've re-posted this in the business forum, as I think that#s where it should be.

Cisco ISE with multiple Network interface

Hello,
I am deploying Cisco ISE 1.2 in a distributed deployment and the requirement is to use external Radius proxy feature. ISE PSNs are designed to have 2 L3 NIC's, Eth0 for administration and Eth1 as client side facing NIC for Radius requests. I am interested to know would Cisco ISE in version 1.2 use Eth1 interface to send RADIUS authentication request to external RADIUS Proxy server.
Could not find above information in Cisco SNS-3400 Series Appliance Ports Reference.
http://www.cisco.com/en/US/docs/security/ise/1.2/installation_guide/ise_app_c-ports.html
Thanks
Kumar

Thanks Ahmad for the reply.
Cisco ISE uses standard RADIUS authentication and authorization port to send request to Exteranl RADIUS proxy. As per the interface/port refrence guide of version 1.2 this is listed that is causing a confusion :-
Eth0
Eth1
Eth2
Eth3
Policy Service node
Session
•UDP:1645, 1812 (RADIUS Authentication)
•UDP:1646, 1813 (RADIUS Accounting)
•UDP: 1700 (RADIUS change of authorization Send)
•UDP: 1700, 3799 (RADIUS change of authorization Listen/Relay)
External Identity Stores
and Resources
•TCP: 389, 3268, UDP: 389 (LDAP)
•TCP: 445 (SMB)
•TCP: 88, UDP: 88 (KDC)
•TCP: 464 (KPASS)
•UDP: 123 (NTP)
•TCP: 53, UDP: 53 (DNS)
(Admin user interface authentication and endpoint authentication)
In external Identity Stores and Resources it says Eth0 is used for (Admin user interface authentication and endpoint authentication), where under sessions it lists that all ports can be used for RADIUS Authentication and Authorization.
I am not sure what I am missing to understand between the two if you can highlight that.
Thanks

Multiple phone hookup question.

How do I hook up multiple phones to a new digital voice installation?Can i just plug into my old phone system input bus?

There can be several ways to connect the eMTA to the inside phone wiring.
First step is to make sure the old telephone service is disconnected. This is normally at the NID, network interface device, the gray box on the side of the house. Unplug the small phone cord from the jack in the NID, and mark it so it will not be connected back by accident.
Once the inside phone wiring is disconnected from the old incoming ILEC service, it is safe to hook the eMTA to the inside phone wiring. Usually the eMTA is installed in a room that has a existing phone jack connected to the inside phone wiring in the home. Take a standard phone cord, plug it in the phone jack in the room and the other end goes to the L1/L2 jack on the eMTA telephony modem. That feeds the jacks in the home to the talk battery voltage on the eMTA and supplies your dial tone and ringing voltage to all phones connected in the home.
Special wiring needs to be done when there is a alarm panel in the home, normally the Comcast installer does this. If the room that the eMTA doesn't have a phone jack, then a inside wire needs to be installed to connect the eMTA to a different point where there is access to the inside phone wiring in the home.

How to add a new network interface adapter?

Hello,
I followed this tutorial (http://www.oracle.com/technology/obe/ovm/ovmel5pvmdb11gr1/ovmel5pvmdb11gr1.htm) to set up a paravirtualized Oracle Enterprise Linux Version 5 VM on Oracle VM Server. It works fine, however I wish to add another network interface adapter (or NIC) to it, however when I try to import into Oracle VM Manager I get the following error:
"OVM-5004 Invalid virtual machine config file. -"
I don't know where the vm config file is so I can't fix that (I did a search for vm.cfg but couldn't find it). I figured since I could access the machine OK I wouldn't worry about importing it into VM Manager, so my question is, is there a way to set up the Network Interface Adapter through the command line on the VM Server (similar to how it was setup)? Or should I try and fix the "invalid virtual machine config file" error so I can import it into VM Manager and then add the extra Network Interface Adapter?
Thanks in advance,
Michael.

The vm.cfg file would be found in /OVS/running_pool/<vm_name>/ -- the default vm.cfg that ships with the template should successfully import into Oracle VM Manager. Once you have the image imported, you can use Oracle VM Manager to add an additional NIC to the VM.

New network interfaces appear / networking fails

Hi
I have a strange behaviour of my ethernet networking interface. Every time I restart the mac the network connection is lost (I usally keep it in sleep and have no problems for days and weeks).
As soon as I enter the network setup I get the message that a new network connection has been found, called "Ethernet (integrated) 1 (or 2, 7, 8 number increases)"
If I look at my network configuration I see a long list of "Ethernet interface ((null))" and in beetween some "Ethernet (integrated) 1)" and the like
It usally takes a couple of restarts of the network preferences and then the interface appears in the "network status" view and the mac connects to the router.
I don't have any external networking cards and the like, just the ibook and a standard router. The router also connects to our mac mini without any problems I it ran for at least half a year with the ibook before this occured.
I would be very thankfull for any help since this is very annoying.
BTW I don't move the computer around and it is connected with a network cable.
Cheers
Peter

How to handle multiple inbound interfaces with WSDL messages

Hi All,
We have a synchronous: Abap Proxy -> XI -> WebService Scenario. The webservice has multiple SoapActions e.g. SearchForProduct_WithX, SearchForProduct_WithY each with different message types. We have tried to use the receiver determination to send the request to the correct soapaction using conditions e.g. if field X in the request is populated use SearchForProduct_WithX action/message.
But when we run it through the proxy we get this error:
<CODE>IF_DETERMINATION.TOO_MANY_IIFS_CASE_BE</CODE>
<ERRORTEXT>Multiple inbound interfaces not supported for synchronous calls</ERRORTEXT>
Does anybody know how we can get around this or how best to deal with the multiple soap actions per wsdl situation.

Hi Yaghya,
We have used conditions in the Interface Determination. Interestingly if we use an HTTP sender adapter we can use this configuration ... but once we try and use ABAP proxies we get the previous error.
Another related question ... when we use the http adapter we get a connection time out exception. Same thing happens if we try and use the wsdl tester at /wsnavigator but we can open the wsdl through the browser. Any idea on this one?
Thanks for all your help.

BadRequest: Virtual machines with secondary network interfaces and virtual machines with no secondary network

I'm trying to create an "ExtraLarge" VM with multiple NICs. The New-AzureVM returns the following error:
BadRequest: Virtual machines with secondary network interfaces and virtual machines with no secondary network
interfaces are not supported in the same deployment, also a virtual machine having no secondary network interfaces
cannot be updated to have secondary network interfaces and vice-versa.
But I have no other VMs. Or at least I did and then deleted them and all their disks. The service has no deployments (either staging or production).
Why is New-AzureVM complaining about a mismatch of VMs with and without secondary network interfaces when no other VMs exist?
I have tried many things to fix this, including the deletion of ALL of my resources. I have deleted and created the service many times, both with an affinity group and without. I have a screen print of the -debug output if your interested.
Thanks for the outstanding help.

Ix4-300d network interface going off-line

I just got a new ix4-300d to use as an iSCSI target in a relatively low-performance requirement file server.
I have used ix4-200d and ix4-300d in the past for iSCSI targets in disk-based backup scenarios wihtout issues.
I am having problems with this one, though. I am attempting to copy data to this new unit (with a VHD mounted from the iSCSI connection to the system), and while data seems to copy OK, at some point the network interface quits working somehow.
When this occurs, the unit still thinks that the interface is configured, and everything seems OK, I just cannot connect. Obviously, this causes my iSCSI initiators to die, and the VM hosted crashes hard. At that point, I have to restart the storage unit, and then reconnect my initiators, and then bring everything back online.
I've updated the firmware to the latest, but it wasn't that far out of date. I've found an article titled "Network storage device is not assigned an IP address" in the knowledgebase that points ot a problem with the software in the 4.0.2 series, and I was at 4.0.6, and am now current in 4.0.8. I am testing the process again, but wanted to check with the community to see if anyone has experienced anything similar and/or could offer some idea of why this interface quits working.
For what it's worth, the other units I have worked with were all in the 3.x series of software.
Thanks for any help/information anyone can provide.
Solved!
Go to Solution.

Hi chloeroxymax,
Do you have discovery enabled?
If not, check the box for "Enable discovery with iSNS" under the iSCSI settings and select "Use local iSNS server".
Then, on your iSCSI Initiator, go to the Discovery tab. Click "Add Server" under iSNS servers and enter the IP address of the NAS.
The device should show up under the Targets tab (you may have to click the refresh button)
On your other NAS devices, go to the iSCSI settings page and select "Enable discovery with iSNS" but select "Use external iSNS server" and type in the IP address of the ix4-300d NAS.
This may help things run smoothly. If the device is still disconnecting, I would recommend contacting technical support since this is a new device and you are covered by the warranty for support.

Changing a Network Interface in DAG Replication Network after going P2V

I have a DAG member suffering severe hardware failure so I have gone P2V with it. It's functioning fine, except that the DAG Network Interfaces have changed - The MAPI Interface was on "Local Area Network" on the physical server, and is now
on Local Area Connection 7 on the VM. However, the DAG settings still point to "Local Area Network" and will not let me change it. Same thing for the replication network.
I have lost redundancy due to this, so I need to get it repaired pretty promptly.
Removing and re-adding the subnet in the DAG network has no effect - it still references the old physical NIC instead of the new virtual NIC, despite the new virtual NIC having the same IP as the old physical NIC.

Try to change the network binding on the server
http://technet.microsoft.com/en-us/library/cc732472(WS.10).aspx
Try to delete the hidden network adapters as well.
Open Device Manager, from the File menu, expand the View and select the Show Hidden Devices option. This will enable and show any old un-used devices in the window

Fake Network Interface - What Is It, and How Do I Get It?

I'm in the process of setting up Linux-VServer, which supports OS level virtualization. It's like running a VM, only instead of using an abstraction layer to create fake hardware and host another OS, the kernel just runs multiple userspaces and makes sure they don't touch anything they're not supposed to.
Anyway, like many VM solutions, networking is a bit funky. They create fake interfaces that seem to exist only in the kernel, then use iptables to mask them with NAT so it still works on a network. The trick is that I'm not sure how they're creating fake interfaces, so I don't know how to replicate it on Arch. Here's a page describing the process: http://linux-vserver.org/Networking_vserver_guests
On Debian, they add this to /etc/network/interfaces:
auto dummy0
iface dummy0 inet static
address 192.168.1.250
netmask 255.255.255.0
What are they using to make this work? Is there a good way to replicate it under Arch?
Last edited by arew264 (2009-03-26 03:18:19)

I ran `ip addr add 192.168.1.4/24 dev eth0 label eth0:1`, which adds an IP address to eth0.
This works better than the solution the vserver wiki recommends because I can give the guest a public IP address.
Is there a way to do this in /etc/rc.conf or the network daemon?

Cannot see network interface counters under Solaris 10 with Sun SMA

Hi,
Noticed this a few weeks ago. When I do a discovery of a Sun server running the Net-SNMP SMA that is a zone, I can see the network interfaces:
.1.3.6.1.2.1.2.2.1.2.1 = STRING: lo0:1
.1.3.6.1.2.1.2.2.1.2.2 = STRING: ipge1:1
.1.3.6.1.2.1.2.2.1.3.1 = INTEGER: softwareLoopback(24)
.1.3.6.1.2.1.2.2.1.3.2 = INTEGER: ethernetCsmacd(6)

.1.3.6.1.2.1.2.2.1.5.2 = Gauge32: 100000000
But the counters all come up as 0:
.1.3.6.1.2.1.2.2.1.8.1 = INTEGER: up(1)
.1.3.6.1.2.1.2.2.1.8.2 = INTEGER: up(1)
.1.3.6.1.2.1.2.2.1.9.1 = Timeticks: (0) 0:00:00.00
.1.3.6.1.2.1.2.2.1.9.2 = Timeticks: (0) 0:00:00.00
.1.3.6.1.2.1.2.2.1.10.1 = Counter32: 0
.1.3.6.1.2.1.2.2.1.10.2 = Counter32: 0
.1.3.6.1.2.1.2.2.1.11.1 = Counter32: 0
.1.3.6.1.2.1.2.2.1.11.2 = Counter32: 0
.1.3.6.1.2.1.2.2.1.12.1 = Counter32: 0
.1.3.6.1.2.1.2.2.1.12.2 = Counter32: 0
.1.3.6.1.2.1.2.2.1.13.1 = Counter32: 0
.1.3.6.1.2.1.2.2.1.13.2 = Counter32: 0

.1.3.6.1.2.1.2.2.1.15.1 = Counter32: 0
.1.3.6.1.2.1.2.2.1.15.2 = Counter32: 0
.1.3.6.1.2.1.2.2.1.16.1 = Counter32: 0
.1.3.6.1.2.1.2.2.1.16.2 = Counter32: 0
.1.3.6.1.2.1.2.2.1.17.1 = Counter32: 0
.1.3.6.1.2.1.2.2.1.17.2 = Counter32: 0
.1.3.6.1.2.1.2.2.1.18.1 = Counter32: 0
This happens consistently across all zones we have running. We can monitor traffic for a zone via the hwardware node SNMP daemon, but certainly seems like we should be able to also monitor network interface utilization via SNMP from any zone as well.
Has anyone encountered this / know of a fix or workaround for this? We have a valid Sun support contract but they unfortunately have been REALLY BAD about answering questions related to the SMA Net-SNMP agent thus far.

Why are you trying to run an old obsolete pre-release version of Solaris 10?
I'd suggest that you install the final released product.
