Multiple NICs; Building Arch Router

Hi Group,
I know how to do this with Gentoo, but I'm new to Arch and was hoping to get a quick start down the path.
What's the best and/or procedurally correct way to add ethernet NICs to an Arch box.
I will install with 1 NIC just to make it simple and easy, but will add 2 more NICS to do routing to 2 different subnets on my network.
I know once the 2 additional nics are installed, I need the right nic driver/modules.
I also know how to configure them (i'll be using static ip's) using ifconfig.
But I'm not certain what files I need to edit to configure the other aspects of networking under Arch?
Is it rc.conf that needs additional entries?
Others too?
Thanks for your time and patience.

Hehe, no no, nothing exotic here, all standard and cheap.  :-)
Excellent, rc.conf and that's all.  This is helping me unclench my jaw, heh.
I recently installed an Arch router on a fit-PC.. working with it right now.. so cool
heres a pic of my Arch router beside my old 3com.. that died after firmware update
Very cool router setup; I've gotta take a look at these slim Fit jobbers.
Thanks a bunch for the speedy reply; huge help.

  • Select TCP UDP route to multiple NIC

    I have two NIC cards (Broadcom & Realtek) installed in my system (Windows XP x64) running LV 8.6 Dev Suite.  Whenever I send/receive TCP or UDP traffic, labview always uses the broadcom card.  Is there a way to work around this issue so I specify which NIC to use?  This is a big deal for me because I'm required to utilize multiple NIC cards for my works.  Thanks

    Since at least LaVIEW 8.5 there is an extra input "net address" on the TCP Create Listener and UDP Open that allows you to define the network address to bind the underlaying socket to. You shouldn't need that for TCP Open Connection since at connection establishment the according interface is selected automatically based on the routing requirements for the specified remote address.

  • Arch Routing

    If I wanted to build a router (at least 3 different NICs, all routed) and load balancing server using arch as a base, what packages would I need/use and can anyone point me in the right direction as to telling me how to do it??  Thanks!!!   

    you'll want iptables for firewalling and NAT, and just the standard commands 'route' and 'ifconfig' should be enough for the rest
    good luck

  • MAXL - using multiple Dimension build rules in single script...

    I seem to be having problems running multiple Dimension build rules in a single MAXL script, is this a known problem or just an issue that I'm having? The build rules independently work as designed but when joined into a single script the script hangs...
    So, this is a 2 part question...
    1) Does MAXL not play nice when using multiple Dimension load rules in a single script?
    2) Do I need to run the build rules independent of each other?
    Also, is there some type of refresh/update on the cube that you can use in the script and would it be necessary...?
    Thanks for any light you can shed on the issue.
    Adam,

    I've written multiple dimension build statements as a part of 1 long MaxL statement. I'm executing this MaxL via a shell script (that replaces the variables such as username, password, servername, file path etc.) I've not seen any issues doing so.
    However, I've noted that, number of imports statements in 1 single MaxL command does not bode well for more than *60* import statements at once. So, if you're using more than 60 source files to build your dimensions, please consider breaking up your MaxL into multiple statements.
    Note: All but last of the import statements have 'deferred' re-structure specified. It speeds up the build process.

  • 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

  • Windows host cannot establish Ethernet link to Arch Router

    This is a weird problem.
    I have a Windows host about 20 meters away from my Arch Router, the Ethernet cable goes into the wall, with wall sockets, so it's a total of 3 cables (1 in wall, 1 @ router, 1 @ host). I've tested the Ethernet cables with a LAN tester, they are all fine. When I connect the host to a Linksys router using the same cables, an IP address is obtained and the link is up and running.
    But when I connect the host to my Arch Router (an Arch computer with some network cards), no ethernet link at all is detected. No lights on the ethernet card of the host, and ethtool on the router reports the link being down. I have connected my laptop to this ethernet card of the router and it works just fine, I get an IP and I can surf the web etc.
    I really have no clue why this other host cannot establish a link. Does anyone have a clue what the problem might be?

    pyther is right. Check for Auto-MDIX support on your network cards.
    What network cards are you using?
    Rule of thumb:
    Auto-MDIX is a requirement in the Gigabit Ethernet specification, so proper Gigabit capable cards will work 99% of the time whatever cable you use.
    Fast Ethernet (100mbit) and below does not have Auto-MDIX in it's specification, so those 9 out of 10 of those cards will not perform it! When connecting these directly to another network card, use a cross-cable.
    Also make sure the network cards are in working order. I assume the ArchRouter PC's network runs fine when you connect that to your Linksys router?

  • 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.

  • Multiple Dimension Builds using MAXL

    We currently use ESSCMND to perform multiple dimension builds and data loads. We have been using the "INCBUILDDIM" in Escmnd to update the outline with multiple files without restructuring until the last file. Is there an equivalent command for MAXL ??

    Yes, you can mimic the BEGININCBUILDDIM command from ESSCMD in version 6.5. I've appended a sample script below to show that functionality. Until you upgrade to V6.5 you could shell to Esscmd and do your dim builds there. login 'xxx' 'PASSWORD' on 'LOCALHOST'; spool on to 'd:\ESSBASE\CLIENT\OUTPUT.LOG'; alter system load application 'SAMPTEST'; alter application 'SAMPTEST' load database 'BASIC'; import database 'SAMPTEST'.'BASIC' dimensions from server text data_file 'ACCTBLD1.TXT' using server rules_file 'ACTBLD.RUL', from server text data_file 'ACCTBLD2.TXT' using server rules_file 'ACTBLD.RUL' preserve all data on error append to 'ERR.OUT'; spool off; logout; exit;

  • 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 .... ?

  • 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!
