Multiple NIC (eth), VLAN, bridge & netctl profiles

Hello,
I need to configure the following network setup on my Archlinux Gateway :
eth0 : LAN, static IPv4 and v6
eth1 : WAN (internet) dhcp IPv4, static v6
eth0.100: no address.
eth1.100: no address
brfbx : bridge on eth1.100 & eth0.100, no address.
I managed to get that up and running using a netctl profile for each line above, but I can't find a way to make it work on boot : obviously the profiles need to be brought up in a specific order... any idea on how to do that ?

do I even need to set up multiple profiles if I "just" have to bridge the Network?

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!

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.

[SOLVED] /etc/resolv.conf vs. the DNS field in netctl profiles

I'm a bit confused about the current role of /etc/resolv.conf. The Netctl profile documentation has a DNS field, so has /etc/resolv.conf become functionally obsolete when using netctl? Or is /etc/resolv.conf still useful when you have multiple interfaces, as it specifies DNS servers for all interfaces?
Last edited by pgoetz (2014-08-30 11:51:50)

From https://wiki.archlinux.org/index.php/resolv.conf:
dhcpcd, netctl, NetworkManager, and various other processes can overwrite /etc/resolv.conf.

Multiple NIC Issues

Hello everyone. I'm in the process of certifying a system with four dual-port gigabit ethernet ports. I can pass all tests with only one of those dual-port cards enabled, but when I have any more I fail the test.
My question is has anybody had any luck with >2 NICS using the same driver? Specifically an Intel e1000g driver?
-James

Kevin, will this fix the problems with trying to do installations with
multiple NICs, or is that still out there??

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.

Hello!
I have Huawei 3G USB modem.
$ lsusb | grep -i huawei
Bus 004 Device 007: ID 12d1:1436 Huawei Technologies Co., Ltd. E173 3G Modem (modem-mode)
I am trying to make netctl to auto-switch to internet connection via this modem as soon as I plug it in.
Following Arch Wiki, I made internet via wvdial working fine:
$ sudo wvdial kymp

Seems like something is wrong in netctl profile and I need to teach netctl to use wvdial instead of whatever-it-uses-now for mobile_ppp connection.
So the question is: "Is this possible to make netctl profile based on wvdial connection? Or is this possible to fix abovr netctl mobile_ppp profile?"
Any help is appreciated! Thank you!

Thanks for sharing this bit of information. This solved the issue for me. But before fixing this, I also had to change the file at another position: I had to escape the quotes around the IP in the connect string setting the APN, so that it now looks like this:
${AccessPointName:+'OK-AT-OK' 'AT+CGDCONT=1,\"IP\",$(quote_word "$AccessPointName")'}
Without this change, I was getting errors like this:

Saving multiple images while in bridge after editing in CR

I have a question involving saving multiple images while in Bridge after they were edited in camera raw PS CS4. I usually view my images in Bridge and select the ones I want to edit in camera raw. I then open the images in camera raw and make the edits which I want to the first image of the group. I then click on the select all button on the top left corner. I then click on the sychronize button and choose the edits from CR which I want to carry through the whole group of images. I then click on the save images button on the bottom left of the CR page. This now brings me back to bridge where I'm looking at the images in their edited version.
This is where the question begins. At this point, I thought the edited made in CR were saved to the images folder located on my computer. But up to this point when Ive gone back to the image folder and looked at the images they were still in their original unedited state although the edited versions showed up in Bridge.
At the point, where I am looking at the edited photos in bridge, do I have to go through another step to save the edited images in Bridge so they will transfer over to the image folder where the images are stored in my computer?

I was looking for the metdata in another window. Ok . I found it and HQ thumbs was checked already. I can see the edits from CR in the Bridge window.
After I check save image in CR, does the edited info get saved only to Bridge or should that be saved all the way to my image folder?
The problem is that when I exist Bridge and look in the image folder the changes I made in CR are not there. How do I get those changes from CR saved to my computer (my pictures)?

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

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.

Netctl profile works flawlessly unless called by netctl-auto

I have four wireless profiles in /etc/netctl and all of them work just fine when used manually, i.e. netctl enable <profile> or netctl start <profile>, but when I set up netctl-auto one of them keeps failing.
The three others are identical except for the SSID and the WPA key so I'm including just one of them here along with the one the keeps failing, but there's really nothing special here. The only difference is that the one that keeps failing has a hidden SSID.
One of the three which work:
Description='WiFi: AMPERSAND'
Interface=wlan0
Connection=wireless
Security=wpa
IP=dhcp
ESSID='ampersand'
# Prepend hexadecimal keys with \"
# If your key starts with ", write it as '""<key>"'
# See also: the section on special quoting rules in netctl.profile(5)
Key='0f20f8g0fg2'
# Uncomment this if your ssid is hidden
#Hidden=yes
The one that doesn't:
Description='WiFi: HANLUKIO'
Interface=wlan0
Connection=wireless
Security=wpa
IP=dhcp
ESSID='kjKJls83jpkskKkkUyasjqKAS'
# Prepend hexadecimal keys with \"
# If your key starts with ", write it as '""<key>"'
# See also: the section on special quoting rules in netctl.profile(5)
Key='CCyzJvIVljL9hsHSbhspPhs929c0hLssh38sPssofo382d8OS320dgSop3hfIGdi32GF'
# Uncomment this if your ssid is hidden
Hidden=yes
The wiki doesn't seem to mention anything specific concerning a hidden SSID and netctl-auto, and since all four work flawlessly when used manually, I'm out of ideas. I'll try setting $NETCTL_DEBUG on the next try and hopefully that will output something meaningful but that wont be till next week and I was curious if anyone knew off the bat what the issue might me.

As I understand man netctl.special, the netctl-auto does not honor the WPADriver parameters in the profiles, because it works on the interface level. Hence, the "Hidden=yes" is not parsed and the hidden ones are probably discarded.
You should be able to add the parameter "scan_ssid=1" (or "Hidden=yes" - not sure) to a hook for the interface in /etc/netctl/interfaces/

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

Hi Sir,
Sorry for the dealy .
Please run the following command to check what physical NIC was bound to external virtual switch:
PS C:\Users\administrator.SERVERLAB> get-vmswitch
Name SwitchType NetAdapterInterfaceDescription
Internal Internal
New Virtual Switch for andy Internal
qostest Internal
team2 Internal
External External Intel(R) 82579LM Gigabit Network Connection
