OATS and multiple NICs

on a controller system with multiple network interface, is there a way to force OATS to use a specific one????
our scenario: The Controller system has NIC A and NIC B. All OATS agents are connected only to NIC B. Yet all OATS services (at ports 8088,9001, etc.) are for some reasons bound to just NIC A. We can ping and connect to those agents on NIC B but can't talk to the services on NIC A.
Ideas? Thanks for any inputs

The WebLogic management console is the most likely place to look. I recall that you can change the ports here, so the NIC management may be possible as well. The JMSServer may be something to investigate after you are logged into the Console. Also the Console-> Servers->AdminServer(admin) has a general configuration setting named "Listen Address".
http://localhost:8088/console
username=oats and the password is the password you previously chose during the install.
Here is another suggestion from the WebLogic guide.

Udev rules config and multiple NICs

So I have four NICs and I want them all set up on individual subnets with static IPs. eth0 is connected to my internet router. So, per the Arch wiki, I tried configuring /etc/udev/rules.d/10-network.rules like so:
SUBSYSTEM=="net", ATTR{address}=="08:00:27:4b:c0:38", NAME="net0"
SUBSYSTEM=="net", ATTR{address}=="08:00:27:ca:75:f6", NAME="net1"
SUBSYSTEM=="net", ATTR{address}=="08:00:27:24:26:4b", NAME="net2"
SUBSYSTEM=="net", ATTR{address}=="08:00:27:35:10:a7", NAME="net3"
and my /etc/rc.conf like this:
# Network
interface=net0
address=192.168.1.11
netmask=255.255.255.0
gateway=192.168.1.1
interface=net1
address=192.168.101.11
netmask=255.255.255.0
interface=net2
address=192.168.102.11
netmask=255.255.255.0
interface=net3
address=192.168.103.11
netmask=255.255.255.0
The problem is upon booting up, the only card that gets configured and brought up is net3. I'm not really sure where to go from here to start troubleshooting. Thanks if you can help!

You have to use something else (e.g. netcfg) than network to configure multiple interfaces. The rc.conf configuration of multiple interfaces is deprecated also.

MDNS/Bonjour switchs randomly between multiple NICs

Dear Community,
I have a problem with a MacServer and multiple NICs...lets name it MSERV
NIC1 goes into the WWW (194.x.x.x) (Protected with ASA firewall)
NIC2 goes into LAN (172.x.x.x) (no firewall)
I need the WWW NIC for ProfileManager and also the LAN NIC for filesharing and TMB.
Both IPs are reachable from our LAN. DNS is good (nslookup shows up as expected) but mDNS/Bonjour makes some problems:
If I do ping MSERV.local sometimes it resolves the 194 and sometimes the 172 address.
This is a big problem for our time machine server backups! When clients choose the 194-path when they discover their backup target on the server, we generate a HUGE load on our ASA firewall.
How can I force Bonjour only to use the 172er LAN NIC.
Or did I get something dramatically wrong?
Any suggestions?

Thank you for your reply!
So you mean to disable Bonjour on the server and set up DNS name as TM target?
Problem is here: How can I do this? Only way I know to connect to my backup server on clients is
System Prefs. -> TM -> Choose Disk. And as far as I know is this a Bonjour connection, right?
When I disable Bonjour service on the server (already tried!) my clients are unable to connect to their target.
Any thoughts?
You should not need to disable Bonjour. Bonjour aka. mDNS uses the .local domain suffix if you use a hostname like MSERV.local it will use Bonjour to try and find the TCP/IP address. (We will ignore the possibility someone might use the .local domain in an Active Directory setup.)
If your using a full-blown DNS e.g. server.domain.com then this is nothing to do with Bonjour and where it will point to is up to your DNS server. In this case you would point it to the 172.x.x.x IP address of the server.
As you want the same server to be contactable via the WAN interface as well for the rest of the work to access what you will want to do is have a 'split-horizon' DNS setup. With this the internal machines use an internal DNS server which points to the internal IP address of the server. You will also have the same domain hosted externally and the same server name but pointing to the external WAN IP address. What you do then have to be careful about is to ensure that all the external host names in that domain are defined also on the internal DNS server even if they are servers hosted externally. For example if you have a www.domain.com server hosted externally so it only has an external (public) IP address then you will still need to define this on your internal DNS server so your internal machines know where to find it, since your internal machines will be using your internal DNS server. If you fail to do this then while the outside world using an external DNS server may be able to access your www server, your internal machines would not be able to because your internal DNS server would otherwise say it does not exist.

Domain Agents and E6900 with multiple NICs.

Hello,
I have some issues configuring Sun management Center 3.6 (and 3.6.1) on a network with this characteristics:
2 x E6900 (with 2 Domains each one)
1 x v210
The Server Component of Sun Management Center is installed on the v210. In this machine are installed the Platform Agents of the 2 System Controllers of the 2 E6900.
Each domain has installed de Sun Management Center Agent.
The network configuration of the Domains is this:
Each domain has 3 NIC on 3 different network interfaces, and each NIC has its own hostname. One of this NIC is destinated to the administration network to be used for the Sun Management Center. This nic, as I said before, has its own hostname but it its different of the nodename (the node name is the same as the public interface of the domain, not the administration interface).
The Domains does not use DNS, and the information included on the /etc/hosts is related to local NICs and the NICs of the other Domains, but anyone contains the NIC of the admin interface of other domain nor the NIC of the v210.
The v210 does not has DNS neither, and has only their own information on /etc/hosts.
All Domains has Solaris 9, and v210 has Solaris 10.
Basically the problem is:
"The Domain Agents cannot communicate with SunMC Server", when I manually add each agent. The discovery process doesn't work neither.
I checked the domain-config.x of one domain and it shows:
agent = {
agentServer = "venwas1"
logicalAddressMode = "ip"
snmpPort = "1161"
"venwas1" is the hostname of the public interface, nor the administration interface.
I changed the value for the hostname of the administration interface with no success; then changed for the ip address of the administration interface; and no success neither.
The default platform agent works, but does not appers with the corrent icon on the SunMC console. Its appears like a folder icon, and the documentation said that the Platform Agents is represented with a specific Icon.
Please, anyone can help me ?
Thanks in advance.

Hi Alejandro,
I checked the domain-config.x of one domain and it
shows:
agent = {
agentServer = "venwas1"
logicalAddressMode = "ip"
snmpPort = "1161"
nwas1" is the hostname of the public interface, nor
the administration interface.
I changed the value for the hostname of the
administration interface with no success; then
changed for the ip address of the administration
interface; and no success neither.If you just change the hostname or IP, but don't do anything else, it won't work as the Agent has already created security keys for that old entry and needs to be reseeded. Change the entry to the IP that's on the same network as your SunMC Server, then run this command on the Agent while it's turned off:
/opt/SUNWsymon/sbin/es-run base-usm-seed.sh -s <SEED> -c agent
..replacing <SEED> with the same seed/password you used on your SunMC Server. Then start the Agent back up, wait for it a couple minutes, and try to make an icon for it again.
The default platform agent works, but does not appers
with the corrent icon on the SunMC console. Its
appears like a folder icon, and the documentation
said that the Platform Agents is represented with a
specific Icon.If the icon is incorrect then your SunMC Server is missing some files (or you've found a bug). You'll want all these addons installed on your Server:
Dynamic Reconfiguration for Sun Fire High-End and Midrange Systems
Sun Fire Midrange Systems Platform Administration
Sun Fire Midrange Systems Domain Administration
If you think you may be missing some (look in /var/opt/SUNWsymon/install/install.[timestamp] to see how you answered questions during your last install) you can run /opt/SUNWsymon/sbin/es-inst again and point it to your distribution media and it will only ask about packages that may be missing. If you do end up adding in some of the Midrange addons then a simple Console restart should refresh your Platform icons.

ISE 1.2 - Multiple NICs/Load Balancing for DHCP Probe

Hello guys
Just prepping an ISE 1.2 patch 8 setup in our organization. I am going for the virtual appliances with multiple NICs. It will be a distributed deployment with 4 x PSNs behind a load balancer and there is no requirement for wireless or guest user at the moment. I've got 2 points I will like to get some guidance on:
Our DC has a dedicated mgmt network and I plan to IP the gig0 interface of the PANs, MNTs and PSNs from this subnet. All device admin, clustering, config replication, etc will be over this interface. However, RADIUS/probe/other user traffic to the ISE PSNs will be over the gig1 interface which will be addressed from another L3 network. Is this a supported configuration in ISE?
I intend to use the DHCP probe as part of device profiling and will ideally like to have just an additional ip helper to add to our switch SVI config. Also, it will appear that WLCs can only be configured for 2 DHCP servers for a given network so another consideration for when we bringing our WLAN in scope. We however use ACE load balancers within our DC and from what I have read, they do not support DHCP load balancing. Are there any workarounds to using the DHCP probe with multiple PSNs without having to add each node as an ip helper/DHCP server on the NADs?
Thanks in advance
Sayre

Hello Sayre-
For Question #1:
Management is restricted to GigabitEthernet 0 and that cannot be changed so you should be good there
You can configure Radius and Profiling to be enabled on other interfaces
Even though you are not using guest services yet, you can dedicate an interface just for that. As a result, you can separate guest traffic completely from your production network
Take a look at this link for more info:
http://www.cisco.com/c/en/us/td/docs/security/ise/1-2/installation_guide/ise_ig/ise_app_c-ports.html
For Question #2
If you are using a Cisco WLC and running code 7.4 and newer you don't need to mess with the IP helper configurations.
The controller can be configured to act as a collector for client profiling and interact with the DHCP thread along with the RADIUS accounting task that is running on the controller. The controller receives a copy of the DHCP request packet sent from the DHCP thread and parses the DHCP packet for two options:
–Option 12—HostName of the client
–Option 60—The Vendor Class Identifier
After this information is gathered from the DHCP_REQUEST packet, a message is formed by the controller with these option fields and is sent to the RADIUS accounting thread, which is in turn transmitted to the ISE in the form of an interim accounting message.
Both DHCP and HTTP profiling settings are located under the "Advanced" configuration tab in the WLC
On the other hand, you can also use Anycast for profiling. You can check out some of Cisco Live's sessions for more info on that. Here is one that is from a couple of years (There are more recent ones that are available as well):
http://www.alcatron.net/Cisco%20Live%202013%20Melbourne/Cisco%20Live%20Content/Security/BRKSEC-3040%20%20Advanced%20ISE%20and%20Secure%20Access%20Deployment.pdf
I hope this helps!

Weblogic Cluster on a machine with multiple NIC

Out Setup
          One Quad Machine
          2 NIC - one ip address on each
          Two weblogic installations
          Each Instance is listening on one address and port 7001.(managed servers)
          Admin Server on one of the ip and port 8001
          Both managed servers part of a cluster.
          While i check weblogic console i see both the managed server
          having almost same number of frames incoming and outgoing.
          If i check 4 processers all 4 of them working eqaully same
          during out load test..(almost 85%)
          But i check NICs only one of them seems to be working really hard..
          and another one so..so.. what could be the problem??


          Weblogic 7 has a new concept called network channel, where there is a section talking
          about clustering over multiple NIC cards. I was confused by the cluster address in
          customized network channel (no example there). I tried to use multiple NIC cards
          for the purpose of network failover, but failed in clustering environment, although
          I succeed in single server environment.

ACS 5.4 Multiple NIC Questions

I've read that 5.4 includes support for multiple NICs (appliance and VM). My question is what can these NICs be used for? I know one must be a dedicated management link, and the other three support TACACS/RADIUS. Does this mean that each NIC can have a separate IP address and thus act as a separate AAA target or are the links just used for aggregation?
If this posts answers your question or is helpful, please consider rating it and/or marking as answered.

Hi Chris,
If you're running 1121 with ACS 5.4 and looking at Table 4-4     ACS 5.4 Functional Interface Distribution Among Network Interfaces. then the answer is that you may set up any interface for tacacs/radius authentication. However, management interface should be setup for gig0 only. Currently, it doesn't support NIC teaming/bonding. However, it sometimes create issues with replication.
http://www.cisco.com/en/US/partner/docs/net_mgmt/cisco_secure_access_control_system/5.4/installation/guide/csacs_hw_ins.html#wp1179311
In case you are running 3415 appliance, the only difference is that it supports reduduncy but that only applies for Cisco Integrated Management Interface (CIMC)
step 4. Set the NIC mode to your choice for which ports to use to access the CIMC for server management

Bonjour not finding anything from PC with Multiple NICs

We have two Network Interface Cards in each workstation at work to access two separate Physical Networks. Both networks provide access to ZeroConf (Bonjour) IP Printers.
Bonjour discovery fails intermittently on the two different networks. Occasionally Printers on one network, the other network, both or neither are visible from various workstations.
Is mDNSResponder aware of multiple NICs? Is there a way to force mDNSResponder to only search for printers on a particular subnet?

The second network adapter was installed after the VPC, indeed.
In the dropdown menu in the VPC networking settings there was only one network adapter to chose because the description for both physical network cards were the same. Therefore I cannot assign for virtual NICs different physical network adapters.
Finally I coped with the problem:
- I uninstalled one of the adapters (removing the drivers, too),
- edited the INF file in the adapter drivers and changed the description of the adapter
- I reinstalled the adapter with the altered driver (with the INF file changed).
Then, in the VPC networking settings both physical adapters appeared (one with the altered description).
I Wonder if that will cause any problems later ;)
Thanks for your replies :)

WOL question. SCCM server with multiple nics.

Hi,
I have a sccm server with multiple nics, I can wake up any machine using a 3ed party magic packet utility, if I set a schedule and use sccm wol functionally the machine never wakes up. As I pointed out my server has multiple nics, does anyone have a sccm
server with multiple nics with sccm built in wol functionally working?. I am curious on how you achieved this.

Hey Garth,
Yes the problem is solved but we had to buy a 3rd party power management utility to accomplish WOL. Because we have many different subnets in our environment we found that this was the fastest way to get WOL working,
So out of the box SCCM would not work for us, with a 3rd party utility that had an SCCM plugin WOL now works flawlessly.

Multiple NICs?

Hey; can miggui handle source and target servers with multiple NICs/IP addresses? I have a DNS/DHCP server to migrate that services two separate VLANs, and I want to make sure I'm not going to blow the whole thing sky-high.
Thanks.

The Migration DHCP leases file issue has been fixed in the jumbo patch that just went into the oes2sp1 and sp2 updated channels a couple days ago. (bug 561928 - issue below).
Steps to Reproduce:
1. Setup NW server (6.5 SP 7 in this case)
2. Setup OES server in the same tree. Remove edir replicas.
3. Setup DHCP on both servers. NW should be configured with a range of 2
address. OES should have the dhcp server setup.
4. Run a windows client with one nic. Get a DHCP address and note the ip
address given.
5. Run the Novell Migration for DHCP (transfer ID option). Choose the
server-level migration.
6. Run the migration, and then run the post migration step per the
documentation.
7. Start DHCP on the OES box and watch the /var/log/messages. Restart or
/release /renew the address from the client. It will not get the same address
as before, but the second address in the pool. Drop the client and add a v-nic
(if vmware), or have another client try and grab an address. The DHCP server
will say it is out of leases, when in reality the first lease is not being
honored.
Actual Results:
See above
Expected Results:
Expected the first client to get its original DHCP assigned address back,
therefore leaving the remaining addresses in the pool open to new clients.

Detecting multiple NIC's

Hi,
On Windows, a call to gethostname(), followed by
the call to gethostbyname(), will return the hostent
structure where the
h_addr_list[0] .... [1] .. etc, will list all the NICS that
were detected on the host system.
I tried running the same program on Solaris 2.6 which has multiple NICS and the call returned with only a listing for h_addr_list[0] ... and nothing else.
What might be the equivalent call that might do the same work on Solaris .... ?
thanks,
ritesh

Set DNS to automatic across multiple NIC's

I have a client with 100(ish) computers. Whoever their IT firm was before us has manually set DNS on most of these computers. I would like to set all NICs on all computers to dynamic, and pull the DNS server address from DHCP server. The problem is I can't
use netsh because it would require the network adapter name. There are multiple NICs on the computers, some are named Ethernet, some are named Local Area Connection, ect.
Is there a way to script this with powershell? I know I can use
Set-DnsClientServerAddress –InterfaceIndex ? -ResetServerAddressesbut I need the interface index, which will be different across various computers. Can I pipe the output of get-netadapter (which shows if index) and input all of them?Any help is appreciated. Thank you!

If you define the DNS servers in DHCP the clients will use it.
With PowerShell you can set the client to use DHCP. look in Gallery for numerous scripts that will do this.
¯\_(ツ)_/¯
Thank you JRV for the prompt response! I have a script that forces all adapters to use DHCP, which does change them from static to DHCP, but this does not change the DNS servers. I was able to get the DNS servers reset to automatic by using
Get-NetAdapter | Set-DnsClientServerAddress -ResetServerAddresses
thanks to Jordan Mills in the Powershell forum. Also, thank you for the script, but most clients here are Windows 7, but I did not specify. Thanks again for the help!

DataSocket fails intermittently with multiple NICs enabled using LV7.1

Using LV7.1 and Datasocket v4.2, I was intermittently (but quite often) having problems reading and writing to the datasocket server (primarily from the server side). My application should read the value in the item and upon finding a specific string it should immediately follow it with a write of a default string. However, it can find the same string multiple times and not complete the write. Logging the errors from the write shows that no error is occurring. The client is not at fault because it only writes the string once every few minutes. I was able to finally show that by disabling the extra NIC on my system running the datasocket server that the connection seems to operate reliably. Both NICs
were set to static IP addresses, but only one was connected. I do have the program writing to "dstp://localhost/UUT" as opposed to a specific IP address (not sure if it matters).
With Labview6.1 I did not have this problem. It was only after I re-compiled my application with LV7.1 that I started having issues.

Philip,
I do not feel I am running out of bandwidth since I have run it successfully on 1Gbit NIC connections on a P4 2.4GHz system as well as a 10/100Gbit NIC on an old 650MHz system with LV6.1. I only do two writes per variable (on up to 8 variables) once every few minutes. I did not seem to be a re-entrant VI issue.
I have created two VIs which should allow you to recreate the failing conditions with multiple NICs enabled. It responds very quickly with one NIC enabled, but when one or two more NICs is enabled, it gets very slow to respond and has some timeouts.
One VI is the writer, the other is the reader. Start both VIs and start all 8 reader loops. Then you can consecutive
ly click on all 8 sender loops. Doing this with and without multiple NICs enabled should show you the problem.
Note: I think the issue I was talking about in earlier posts about getting multiple strings back before it wrote out "Loop" was due to the fact that the writes were not occurring quickly enough and the reads were happening multiple times. Therefore, in these VIs, I revised the read and close timeouts to -1.
I think it would be best if you could call me so we can discuss this issue. If you can email me, I will send you my contact information if you don't already have access to it.

DataSocket and two NICS?

I have an application where I want to communicate through two separate NICs
from one computer using DataSocket. LabVIEW 7.0 now supports multiple NICs
for TCP/IP but is this also possible with DataSocket? If so, how do you
control which NIC you go through? I couldn't find anything in the
DataSocket Server that allows you to specify which NIC you are using.

Hello nealpederson,
Thank you for your question regarding DataSocket. You mentioned that you would like to communicate through two separate NICs using DataSocket. This feature is not available in DataSocket. One possible solution may be to run DataSocket server on the client computers and send data to the desired target IP address on the computer with multiple NICs. However, LabVIEW would most likely send data out on all the cards that you have installed on the computer with multiple NICs.
Other resources can be found on the ni.com website by clicking the support tab at the top of the home page. Then search from Technical Resources at the top of the page for your topic. I hope these resources help! Let me know if you need any other support with this issue.
