Simultaneous multiple network routing?

I'd like to know if it's possible to have two network connections, one ethernet and one WiFi that can be used simultaneously. These connections attach to two different networks where ethernet is a LAN and the WiFi connects to a cable modem.
I'd like to have OSX essentially try the LAN first but if it can't connect that way try the WiFi.
Can this be done?
Please let me know if this is not clear and I'll try to re-explain.
Thanks.

You could do this in a script. I'm not sure how to change the network service order on the fly, but you could down the ethernet interface, fire up your IRC client, and up the ethernet interface. Like this:
#!/bin/sh
# Turn Ethernet off
/System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Support/netw
orksetup -setnetworkserviceenabled "Built-in Ethernet" off
# Fork IRC client
# Since I don't know what it is, I'll substitute TextEdit
/Applications/TextEdit.app/Contents/MacOS/TextEdit&
# Turn Ethernet on
/System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Support/netw
orksetup -setnetworkserviceenabled "Built-in Ethernet" on
exit 0
You could just ifconfig en0 down and ifconfig it back up again, but I read that networksetup was the preferred method.

Simultaneous multiple networks under access connections?

I have two networks at home, one of which uses an ADSL internet connection the 2nd of which serves Network attached storage devices. Each network has a router. I want to use the wireless connection to connect to one network, and the ethernet con, for the other. I've looked through the settings carefully in the Access connections application. I've set profiles for the wired and wireless network adapters. I've unselected the tab to "disconnect from the connection when switching to a different network" but I cannot be connected wirelessly and wired simulatneously. If the wifi adapter is running, I'm working on network #1 with the internet connection I use, and if i pop the ethernet cable in from the second network, instead of having access to my Network attached storage devices, and retaining the wireless connection it seems to disconnect from the wireless connection and just retrieve an IP from the router network #2. I thought about setting up static IP's but that shouldnt be necessary. The adapters should work independently of one another. So whats the deal here? I cant move the NAS's from one network to the other, but I shouldn't need to either.

Take a look to the option "Switching location".
Open AC -> Configure -> Switching location.
Try this: Disable the automatic location switching option.

WRT610N - connected to multiple networks?

Hi all, I bought and set up one of these routers yesterday and initially my laptop reported it was connected to multiple networks, same SSID but different antennae, it meant I could switch between 2.4 and 5.0 GHz without dropping connection and obviously had great connection strength. But after a shut down and restart it will now only connect to one antenna at a time. Which is the correct way for the connection to work, should it be connected to only one antenna at a time?
Thanks in advance.

I've obviously not been clear, when I set up the router yesterday I set different SSIDs for the two bands, LINKSYS1 for 5GHz and LINKSYS2 for 2.4GHz. When I connected to LINKSYS1 I got 2 connections simultaneously, one labelled "LINKSYS1" and another lablled "LINKSYS1 2" both providing a 5GHz connection. I also had another connection at one point called "LINKSYS1 3". Exact same thing happened when I connected to the 2.4GHz band "LINKSYS2" (i.e. I had 2 connections labelled "LINKSYS2" and "LINKSYS2 2" both providing a 2.4GHz connection). Hovering over the network icon showed 2 connections and network and sharing center showed connected to multiple networks. When I restarted it this morning it's only connecting to one and the converage isn't as good (could get 100% signal from outside last night and stream DVD iso's but it's buffering quite a bit today). I've googled it and some other people have mentioned the same thing but they seemed to think it was a fault, but it gave me better coverage than I'm getting today. What I was asking was which is the correct way for it to operate, as one connection or multiple connections.

Can I use my Time Capsule to set up multiple networks, or just one?

Can I use my Time Capsule to set up multiple networks, or just one? We'd like to offer the internet to clients who are at our studio, but don't want them able to access all our computers, so a second network for them would be useful.

Two big IFs here.
Not all versions of the Time Capsule have Guest Networking capability, so it might be a good idea to verify that first. Can you provide the model number of your Time Capsule. it's on the bottom of the device.....starts with an "A" followed by four numbers.
Next, assuming that the Time Capsule has Guest Network capability, the next requirement would be to verify that your modem is compatible with the Time Capsule for that feature.
Basically, you need a simple modem.....not a modem/router or gateway device that is often furnished by Internet Service Providers. If you are not sure what you have, post back with the make and model number of your "modem" and we'll see if we can find some details ont he device.

Does CISCO C3560X VLAN support multiple Network segments which are further configured with HSRP function

Hi Cisco experts,
My name is Kumagai and I need your expert opinions below.
I am trying to configure one VLAN1 support multiple network segments as below.
(this should be a very straight forward configuration and should be OK, I think ? )
interface Vlan1
ip address 172.30.0.0 255.255.128.0
ip address 172.30.31.253 255.255.254.0 secondary
ip address 172.30.61.253 255.255.254.0 secondary
ip address 172.30.71.253 255.255.254.0 secondary
ip address 172.30.4.253 255.255.255.0 secondary
The only issue that is eating me is the above network segments are using HSRP too
and I am not sure is this possible with a combination of VLAN1 supporting multiples which are
further supported with HSRP settings in Cisco environment.
!example of HSRP:
interface Vlan4
ip address 172.30.4.253 255.255.255.0
no ip redirects
standby 4 ip 172.30.4.254
standby 4 priority 105
standby 4 preempt
<<< what will happen if I add the HSRP configuration as below into the above VLAN1 with multiple Network segment ??)
I would like to summarize my "Combined" configurations as below but I need your expert opinions on
whether the configuration below is workable without any problem ??
Or it is a total flop because Cisco does not support the configuration below !!!
interface Vlan1
ip address 172.30.0.0 255.255.128.0
ip address 172.30.31.253 255.255.254.0 secondary
ip address 172.30.61.253 255.255.254.0 secondary
ip address 172.30.71.253 255.255.254.0 secondary
ip address 172.30.4.253 255.255.255.0 secondary
standby 30 ip 172.30.31.254
standby 30 priority 105
standby 30 preempt
standby 60 ip 172.30.61.254
standby 60 priority 105
standby 60 preempt
standby 70 ip 172.30.71.254
standby 70 priority 105
standby 70 preempt
standby 4 ip 172.30.4.254
standby 4 priority 105
standby 4 preempt
Thanking you in advance !!!!!

Hi,
As far as i know we dont set the ip helper address on the radio interface. It should be on the L3 interface of corresposding VLANs i.e.
int vlan 20
ip helper-address 192.168.33.xxx
int vlan 60
ip helper-address 130.20.1.xxx
I'm assuming that your using SVI's (int Vlan 20 and int Vlan 60) rahter than physical interfaces. Also hope you have configured switch port as trunk where this AP is connected.
Modify the AP config as below since you are using data vlan as the native vlan
interface Dot11Radio0.20
encapsulation dot1Q 20 native
interface FastEthernet0.20
encapsulation dot1Q 20 native
Ideally your AP fastethernet configuration should looks like below and not sure how you missed this as this comes by default when you have multiple vlans for multiple ssids.
interface FastEthernet0.20
encapsulation dot1Q 20 native
no ip route-cache
bridge-group 20
no bridge-group 20 source-learning
bridge-group 20 spanning-disabled
interface FastEthernet0.60
encapsulation dot1Q 60
no ip route-cache
bridge-group 60
no bridge-group 60 source-learning
bridge-group 60 spanning-disabled
Hope this helps.

Cant login multiple network accounts on the same client?

Setup:
I have created a simple Lion Server on a new i7 Mac Mini. I have configured Open Directory in Master mode and have setup 4 user accounts. I have enabled the File Sharing service and checked the "Make available for home directories" option on the "Users" file share. I have configured each of the 4 user accounts to use this location as the home folder. I have connected my client machines (all OSX Lion) to the Network Account Server.
Problem:
I can log one user into the client machine, but when using "Fast User Switching" and logging on as the second user I get the following error:
"You are unable to log in to the user account "guestaccount" at this time. Loggin to the account failed because an error occured"
In the console if I search for that user account the related error message is:
11-07-31 12:30:54.993 PM authorizationhost: ERROR | -[HomeDirMounter mountNetworkHomeWithURL:attributes:dirPath:username:] | PremountHomeDirectoryWithAuthentication( url=afp://inntaserver01.local/Users, homedir=/Network/Servers/inntaserver01.local/Users/guestaccount, name=guestaccount ) returned 16
Any thoughts as to why the Home Folder "mounter" failed in this scenario?

Historically you have never been allowed to use Fast User Switching to log in multiple network logins on the same client machine. This certainly applied with Tiger, Leopard, and Snow Leopard. I have not yet personally tried this with Lion.
I believe that the underlying reason for this not being allowed is down to how AFP volumes are mounted. The AFP mount becomes 'owned' by the user that triggers the login. With a network login the first user becomes the owner and this means subsequent attempted network logins are denied access to that share and hence cannot access their home directories.
With Tiger, Leopard, and Snow Leopard servers, one could configure network home directories to be shared via NFS instead of AFP. NFS gets treated a lot different in terms of mounting, and is done more at a system level than a user level. While again I have not personally tried Fast User Switching with NFS shared home directories, this approach is specifically recommended by the authors of AquaConnect (a Macintosh Terminal Server solution) in order to allow multiple logins on the same Terminal Server. This seems to be for the same underlying reason. Using NFS does certainly work for use with AquaConnect and also works for the competing iRAPP Terminal Server product as well.
Unfortunately, Lion Server while it can be made to run an NFS server, will not let you configure using NFS for sharing home directories. I have actually reported this as a 'bug' in Lion server.
Neither the authors of AquaConnect or iRAPP have actually tested this scenario with Lion server yet, but AquaConnect do plan to investigate it. It could make it considerably more difficult to use their products.
So in summary, using NFS to share network home directories in theory would avoid the problem and can be done with a Tiger/Leopard/Snow Leopard server, but cannot be done with a Lion server. It is possible however to mix Lion with older server versions. This might for some people be a possible workaround.
PS. A bonus side-effect of using NFS shared home directories was that this allowed badly written software like Adobe's applications which are otherwise notorious for having major issues with network logins and home directories to work without errors. As an example Adobe Acrobat Pro introduced a bug in version 7.0 which prevented it being able to print-to-PDF (one of the major reasons to buy Acrobat Pro). It tooks two years for them to eventually fix this in Acrobat Pro 8.1 (I know because I spent that two years nagging them to fix it and was a beta tester). Unfortunately they then reintroduced the bug in Acrobat Pro 9.0. Fortunately I discovered this side-effect got round the issue although a clunkier workaround was also possible for Snow Leopard clients by redirecting certain folder paths.

Is it possible to create a configuration profile that will install multiple network printers and their associated drivers

Is it possible to create a configuration profile that will install multiple network printers and their associated drivers?
I was not able to find profile manager on my employer's installation of 10.6 Server. Is this only a feature of 10.7/10.8 server?

10.6 server does not have profile manager, profile manager is only available in 10/7 and 10.8 server
for 10.6 server you'll need to use wgm and server admin
printer management with 10.6, I recommend you read the relevant server manuals regarding
print server and user management, printer management

Solaris 11 host no longer sees a ZyXEL wifi network router

This issue is on a Toshiba Tecra M10 running Oracle Solaris 11.1 SRU 0.5.11-0.175.1.0.0.24.2
The once functional wifi network iwh0 (net1) no longer sees a ZyXEL NBG-416N wifi network router.
The e1000g (net0) can connect to the router when direct connected via TP ethernet cable from the laptop wired ethernet port.
There are other wifi networks visible from iwh0 (net1) when the command 'dladm scan-wifi' is run.
When attempting to connect with the 'dladm connect-wifi' command (I know the command is good I recall it from the shell command history) .. I get "no wifi networks with the specified criteria are available"
The laptop is able to connect to one of the other wifi routers over this interface however not my own router (which appears to no longer be visible from Solaris 11.1).
I am able to connect to it from an HTC mobile phone and a Windows 7 laptop.
Removed wifi cache file /system/volatile/dladm/network-datalink-management:default.cache.0 and rebooted. No joy.
If I boot from the Solaris 11 DVD, I can still not see the expected wifi router.
At this point I am suspecting the ethernet address of the M10 iwh0 (net1) interface.
'dladm show-phys -m' lists the interface ethernet mac addresses (even if not plumbed).
Connected to the router (from alternative system, over wifi) and looked around. Noted the logs had a messages "possible DNS-rebind attack detected: a-0.19-*8d9zff4tq7njzcj.avts.mcafee.com" that seemed to start about the time I lost sight of the network? Can no longer say for sure as I restarted the router and it seems to have lost those log entries.
Contacted the ISP who provided the ADSL/router for use with their FTTC service offering - they are not aware of any 'protection mechanism' on the router that might mask a misbehaving mac-address.
Tried changing the mac-address on the iwh interface with 'dladm set-linkprop -p mac-address=06:05:04:03:02 net1' and ran 'dladm scan-wifi' without success (then reboot with 'init 5') resets to original but after reconfiguring again -still not available.
If anyone can help .. perhaps having seen something like this and solved it .. or even simply help with better troubleshooting, please advise.

Okay .. I changed the routers 'channel selection' from 13 to 7 and this wifi router network ESSID is again visible to the Solaris 11 instance. I expect the other OS's cater for this a little more elegantly?
~ # dladm show-linkprop net1 | grep -i channel
net1 channel r- 7 -- --
~ #
It seems the channel property wont be visible unless there is a connection (I suppose obviously).
I expect another router has moved into the radius close enough to interfere?

Multiple network location servers possible?

As we all know the network location server is an important part of any Direct Access deployment to ensure that DA clients can know whether they are connected directly to the internal LAN or connecting from external via DA.
I have seen discussion about deploying the network location server (simple blank IIS/Apache web site) in an NLB configuration but is there any way to have multiple network location servers for high availability reasons? During the DA configuration
process you can only input a single dns record for the NLS so it does not appear possible. Has anyone found a way to do this?

Hi,
Yes it's a good practice to have NLB in high-availability. So a single FQDN with NLB or HLB as high-availability solution. Major problem is when DirectAccess clients connected on LAN cannot join the Network Location server. They consider they are connected
on Internet not on LAN and try to activate DirectAccess. In such situation, If users can disable DirectAccess (so no force tunneling) they can solve the problem. Once NLS is back online, computer automatically change the firewall profile to domain.

ASDM multiple network objects vs group for rules

I was just curious if there are any performance benefits of using multiple network objects on multiple rules vs consolidating them into fewer rules by grouping them?
For example, I have about 10 lines of NAT exempt rules from the same source to multiple destinations. Is there anything to be gained if I consolidated those into a single rule using an object group for the multiple destinations aside from cleaning up the clutter in ASDM?
Thanks

Hello Tony,
Of course, it will be better because the processing that the ASA is going to use to determine witch rule to match would be decremented, also it would take less space on the configuration file (memory). those are some of the pros regarding creating groups for particular rules.
Sometimes a huge configuration file can increment the CPU usage,etc,etc. so it is better to keep it as small and organized as possible.

Use of multiple networks in projects

Hi,
I know the standard hierarchy in Project systems like we have definition, then main WBS, then networks, then sub WBS and then activities. Now in this standard hierarchy, even though the activities are under WBS elements, the activities are connected to one network and in network graphic we can define the relationship among the various activities.
I mean by using the single network we can achieve the various objectives, then why most of the projects use multiple networks i.e. network per each WBS elements even though these multiple networks are connected to one network only.
Thanks

Hai
The criteria according to which a project is structured using a work breakdown structure and/or networks can vary and depend on the type and complexity of a project. A project can therefore also consist of a work breakdown structure and several /single networks.
For example, the criteria can vary depending on the responsibility and structure of the departments or teams involved, or on how production and assembly are integrated. It is therefore impossible to give a wholesale answer to
the question of how best to structure different types of projects.
As a rule, a project is structured according to two
points of view: structure and process.Network techniques are used for planning and controlling the process flow of projects.
ENJOY SAP

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.

Load balancing using multiple default routes

Hi Guys,
I just want to ask does creating multiple default routes on my router provides load-balancing on my WAN side? As far as i know, for example if I have two default routes on my router and let say I have two users connecting to the internet, the first one might go to the first WAN link while the second user might go to the second WAN link.
Thank you so much
Rex

there are the difference between, load balancing and load sharing..which we need to understand.
load sharing means you have 2 users, user A and User B, user A wants to use ISP1 and user B wants to use ISP2. this is called load sharing. and can be achieved via PBR (Policy based routing).
we should not try to use load balancing for Internet traffic with 2 different ISPs.

Re: Wireless network, router WRT150N. Recently installed in network.
My son is having trouble with his World of Warcraft latency. It starts off excellent but tanks in about 10 secs after he starts playing. I've concluded it must be something with the router. I've tried most of the WoW fixes for latency, but I get same behaviour.
I note some other message threads of same problem, but no fixes. Anybody help?

Log into 192.168.1.1 on your browser (no username, password is admin). Set the MTU to manual and change the size to 1400. Check WoW documentation for tcp/udp ports that need to be opened on the router.
Keep us posted! (",)
