Bringing an interface down using a network profile
I use netcfg to switch between network profiles... but when I switch from a profile using ethernet to a profile using wireless, it just adds the other interface... so that both ethernet and wireless are up.
The only way I know to bring an interface down (say, ethernet) is to edit NET_PROFILES in /etc/rc.conf and put in a profile using wireless, and do /etc/rc.d/network restart.
But is there an easier way? Is there some sort of command I can put inside my profile which uses wireless to bring down the ethernet interface?
Thanks.
I'm not infront of a Linux box right now, but perhaps if you could run, as root:
# ifconfig eth0 down;
of course, replace eth0 with the appropriate interface you wish to take down.
p.s. - I hope i'm not completely getting your question wrong because I feel I may be.

May I start more than one interface at boot using network profiles ?
Hi everybody,
I installed ArchLinux on my laptop and I was playing with network profiles to obtain different configurations of the ethernet and wireless interfaces for home, office etc. Everything works fine using "!" in from of each configuration name in /etc/rc.conf and I found useful the menu option.
As far as I understood each configuration file in /etc/network-profiles/ correspond to one interface only, therefore this utility does not allow me to start more than one interface at boot time. Am I right?
In this case it exist already a script to choose between different configuration for two interfaces?
Thanks in advance
JimmiWelcome to the Apple Community da dad.
Yes you can connect multiple Apple TV's by ethernet.
What do you mean by outside. -
Setting applications to use specific network interfaces
How do I configure my computer such that specific applications will default to a different network interface than all the rest?
I want to set it up so that Adium always tries to use AirPort first and everything else uses ethernet if it's available.
Powerbook G4 1.5 Ghz Mac OS X (10.4.8) 1GB RAMYou can't (normally) get there from here.
What you're trying to do is affect the routing (route certain traffic through a specific interface). The issue is that routing works at the IP level, not the application level. This means that you can tell the system to route a.b.c.d (e.g. the address of the IM server you're connecting to) through a speciic router at w.x.y.z (e.g. the AirPort).
In order to do this, though, you need to have different IP address/subnet masks on each interface.
For example, assuming your wired ethernet is using 192.168.1.2/255.255.255.0 and your wired ethernet router is at 192.168.1.1, and your AirPort interface is using 10.1.1.2 with the AirPort router at 10.1.1.1 you can run the command:
<pre class=command>sudo route add a.b.c.d 10.1.1.1</pre>
and all traffic for a.b.c.d will go over the AirPort link.
Note that it doesn't matter what protocol you use - any traffic destined for a.b.c.d, whether it's AIM, HTTP, FTP or anything else - or what application you use - Adium, Safari, FireFox, etc. - they'll all use the AirPort link.
Note that this technique will NOT work if you have both interfaces on the machine configured in the same subnet, but this is not a supported configuration, so you shouldn't be doing that anyway. -
Use two interfaces on the same network
Hello every one,
I actually starting to work on a cisco project. I'm a beginner on networking and cisco technologie.
For my project we use a router 2921.
We got two network:
- Network A: 192.198.0.X / 255.255.255.0 / Gateway 192.198.0.1
- Network B: 162.168.0.X / 255.255.0.0 / Gateway 162.168.0.1
Each network use switch, Switch A (connecting to network A) is connected to interface G0/0.
And Switch B (connecting to network B) is connected to interface G0/1.
Router well configured as:
- G0/0: ip address 192.198.0.1 255.255.255.0 (network A)
- G0/1: ip address 162.168.0.1 255.255.0.0 (network B)
Every think working fine.
The problem is with this one, we need to connect a computer on G0/2. This computer is configure as network A (192.198.0.10 / 255.255.255.0 and same gateway).
I can't configure G0/2 as 192.198.0.1 255.255.255.0 (network A), cause G0/0 use this adresse.
I can't put this computer on the switch A, my only physical possibilité is to connect him on G0/2.
We just need to use interface G0/0 and G0/2 as a switch on the router with the same gateway (192.198.0.1)
How can i connect this computeur? How can i configure two interfaces on the same network and same gateway?
Thanks youI would just put the PC on a different network, but if you really want it to be in the same network, you could use IRB to connect two of the interfaces on the router at layer 2.
Here is an example config for IRB:
interface FastEthernet0/0
bridge-group 1
interface FastEthernet0/1
bridge-group 1
bridge irb
interface BVI1
ip address 192.168.0.1 255.255.255.0
bridge 1 route ip
Notice that the physical ports do not have IP addresses on them, the IP for the subnet is on the BVI interface. -
Have a 802.11n time capsule, the range of the wireless network has shrunk down to nothing over last few days. Used to be able to use wireless network anywhere in house, but now can only use in my office. Will not connect to iphones, ipad, itouch, or notebook. Worked fine last week, but over weekend just started having issues.
It is very possible that you may have some form of Wi-Fi interference that has appeared recently that is preventing your Time Capsule (TC) from providing a clean RF signal.
I suggest you perform a simple site survey, using utilities like iStumbler, or AirRadar to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible. Look for other Wi-Fis that may be operating nearby. Note those with the strongest signals and which channels they are operating on ... then change the channel used by the TC to be at least 3-5 channels away. -
Hi
I recently upgrade tp 7.0.3 from 7.0.2.
While upgrade i found that i am not able to login to the web server with the admin id "admin" default created in the application server.
The same id i can login to application server , but not in wewb server.
I am getting the mentioned error "You cannot sign in to the Cisco Unified MeetingPlace Web Server interface using preconfigured system profiles".
However if i create a new user in application server and tried logging with the same in the web server it is working fine..
is it a known behaviour wirh the upgrade or i m facing some issue.
Hope i can find a solution here.
Regards
RCRC,
This behavior is stemming from a change in MP 7.0 MR2 to disable the MPWeb login for system profiles. This was an internal change made by the developers to restrict the log on to the MPWeb page by the default accounts created in MeetingPlace upon installation. The change now displays this error when the admin account is attempted to be used for MPWeb login, as you experienced-
Error:[22953] You cannot sign in to the Cisco Unified MeetingPlace Web Server interface using preconfigured system profiles.
You should be able to log into MPWeb using any other user profile that you have either created manually or pulled in from LDAP/Active Directory. You just cannot use the admin account. This is reserved for login to the MP Application Server Administration page only. I am going to work to get this information added to the MP 7.0 documentation with a note for changed behavior in MR2 and above. Here is the note from MP 8.0 documentation-
Note: You cannot use this preconfigured admin profile to access the Cisco Unified MeetingPlace Web Server interface. Instead enter the User ID and password information from one of the other user profiles that have system administrator privileges to sign in to the Web Server.
Please let me know if you have any further questions.
Thank You,
Gerry -
When I look up the 250+ new features of Mac OSX Lion, under address book, there's a new feature that interests me.
"Address Book lets you quickly access the social network profiles for your contacts, including Facebook. Press and hold an email address to select the appropriate profile."
Somehow I can't get it to work. What do I do?Make sure it's on the Template (see the entry for Twitter):
Then update the contact with the relevant info.
For Twitter you can then click and hold the Twitter tag to either View Profile or Send Tweet.

[SOLVED] Cannot bring wifi interface up
Hello,
A bit of a newbie here...
I've just installed archlinux on a laptop and I'm trying to get it to use a static IP on the wireless (already suceeded to get it working with a static IP on the wired network) via WEP to an access point that doesn't broadcast its ESSID.
I have set up a netctl profile which runs at boot time. Said profile seems to run correctly and I even get an IP address for the wireless. However, it doesn't seem to bring the wifi interface up and typing "ip link set <INTERFACE> up" as root seems to have no effect. I have already installed the firmware for the card and I'm not successful in getting a connection.
This is the output of the commands I've tried so far:

Last edited by AMaudio (2013-11-09 21:08:35)Thanks for the pointers, Strike0. The wired-wireless failover scenario does look quite interesting. So I'd like to explore that option more extensively. I attempted to create a master bond/failover connection via netctl with two slaves: one for the wired connection and another one for the wireless connection. For the wired connection I used a netctl profile and for the wireless connection I used a systemd service manually setting up the wireless connection, somewhat following the wiki pages you refer to.
All three services start up correctly, but when I unplug the ethernet cable, the wireless network doesn't take over. It seems that it's not really connected.
Here's the details of my configuration:
The master failover (bond) netctl profile:
# cat /etc/netctl/failover
Description='A wired connection with failover to wireless'
Interface='bond0'
Connection=bond
BindsToInterfaces=('enp2s0' 'wlp2s3')
IP=static
Address="192.168.1.5/26"
Gateway='192.168.1.1'
DNS=('XXX.XXX.XXX.XXX' 'YYY.YYY.YYY.YYY')
SkipNoCarrier='no'
The failover wired netctl profile:
# cat /etc/netctl/failover_wired
Description='Failover wired network'
Interface=enp2s0
Connection=ethernet
IP=no
SkipNoCarrier=yes
## For IPv6 autoconfiguration

Cry for help: a decent network profile manager
Am I the only one that finds the default arch linux network profile management a bit.. lacking? Maybe I just don't have it set up right, but it only works for my ethernet connection and connecting to non-encrypted wireless networks. Problem is, I run WPA2-AES networks at home and at work. I finally got wpa_supplicant properly set up (I'm on wireless right now), but I can't just select the network profile from the menu and be on my way.
Here is what I have to do to get connected right now:
[root@cdl-magnesium chris]# wpa_supplicant -dw -c/etc/wpa_supplicant.conf -Dmadwifi -iath0
[root@cdl-magnesium chris]# dhcpcd ath0
and I'm connected, everything working great. That's fairly simple, right? I'm thinking my network profile has a lot more in it than necessary.
# Network Profile

WPAOPTS="-D madwifi" # use "" for normal operation or specify additional
# options (eg, "-D ipw")
# see /etc/wpa_supplicant.conf for configuration
#AUTOWPA="yes" # automatically configure WPA
If I do a /etc/rc.d/network restart and select the profile from the menu, I get all sorts of errors about not being able to connect to wpa_supplicant (because for some reason it isn't running.. was I supposed to do something about that?).
I'm a bit tired right now so pardon any incomprehensible sentences or questions
ps: while we're on the subject, is there a way to re-sort the items in the network profile list? It always wants to connect to this broken wpa2 profile first, as I think it just goes in alphabetic order or somethin. I guess I should just turn off the timeout so it always waits for me to choose.i'm working on one.

Can I use a network hard drive for time machine
Can I use a network drive for my time machine back up. I currently have a 1TB WD AND its full with mostly videos and other back ups?
Such a configuration is not supported. This does not mean it will not work, but it is not guaranteed to work reliably.
Considering the "mission profile" for a backup strategy, you should consider this an unacceptable application for Time Machine.

Windows Deployment Service. Network Profile Radio Buttons greyed out with R2
Hi All
I have downloaded and setup Server 2008 R2 (not yet activated). I have added the following roles "DHCP Server", "DNS Server", "Active Directory Domain Services" and "Windows Deployment Services". I can PXE boot a test client machine and (using the boot.win from windows 7 dvd) multicast a XP Image to it. This setup is connected via a 100 Mb switch and is an isolated network.
Under windows deployment services - if I right click my server - select properties - network tab "Network Profile is greyed out". I have tried running wdsutil /Set-TransportServer /Server:big /Profile:100Mbps but get the following error message: "Windows Deployment Services Management Utility Version 6.1.7600.16385. Error code 0xC110011F This WDS transport server does not support network profiles.
I have tried this on two hardware setups:
An Intel D915GUX 3GHz 2GB RAM and Marvel Yukon 88E8050 ethernet controller.
An Intel D965 Core2Duo 1.86GHz 2GB RAM and Intel 82566DM Network controller.
Incidently I have done the same setup with Server 2008 (not R2) on the D965 and the Network Profile radio buttons are not greyed out. If I upgrade the same test machine to server 2008 R2 the Network Profile radio buttons are greyed out. Is this a design change, does Server 2008 R2 no longer support network profiles as I am now unable to select 10 100 or 1000 Mbs ?
If more information is required or if anything needs further detail please let me know.
Thanks for any help.
Liam.DIs there any way at all to manually set or control the network profile? In my environment, a SCCM\WDS multicast stream is bottoming out on speed and network utilization when the stream crosses a Nexus 7009 router. Speeds go from 200 Mbps to 20 mbps. I have
a theory that this "new" automatic configuration is placing the clients in a slow network profile that are on the opposite side of the router and I have been unable to find a way to speed of the transmission. I have also ruled out the "master
client" slowing down the stream buy using different clients only connecting to a stream 1 at a time. I have also ruled out the router as the source of the problem by having a VLC client listen to the multicast stream on the same side of the router as
the slow clients. The VLC client (unknown to SCCM\WDS) was able to receive the transmissions at 20 % utilization / 200 Mbps.

[SOLVED] Configuring and using a netcfg profile
Hi guys,
As per the Beginner's Guide I have been trying to set up netcfg to use my network configuration profile https://wiki.archlinux.org/index.php/Be … de#Wired_2
I can successfully setup network connectivity every time I boot using the 'ip addr add 10.1.0.8/8 dev eth0' and 'ip route add default via 10.0.150.1' commands but ideally I'd like a static IP setup automatically.

Now when I manually run 'netcfg -u ethernet-static' it fails and I can't for the life of me work out why...
Is there any other information I could provide? As I said I can use the 'ip' commands to connect using the same addresses.
Please help! Many thanks

According to the netcfg-profiles man page, the netmask value defaults to /24. So your interface is being configured with a 10.1.0.8/24 address, thus making the 10.0.0.0 network (where your gateway resides) unreachable.
You have to specify your /8 netmask explicitly, e.g.:
CONNECTION='ethernet'
INTERFACE='eth0'
IP='static'
ADDR='10.1.0.8'
NETMASK=8
GATEWAY='10.0.150.1'
DNS=('10.0.0.17' '10.0.0.18')
Genius! Thank you so much, it's working now.
I was trying to use journalcfg, however I couldn't work out how to filter it properly or just show the last 20 or so entries.... But anyways problem solved.
Kudos to you p0x8
Thanks all!

My understanding of the uses of port profiles includes the implementation of Nexus 1K/5K etc. and the implementation of VM-FEX correct? These port profiles are then pushed to vCenter to be used by the VM's offloading the networking portion back to UCSM and not the VM admin... Is this correct?
N1k/N5k/UCS VM-FEX port-profiles are used by both the network & VMware administrator. The network administrator creates the port-profile & assigns properties (VLAN, QoS, ACL, etc) - available features differ on each product with N1k offering the most features. After the the port-profile is create it is automatically advertised in vCenter. The vCenter admin then assigns port-profiles to VM interfaces and vmnics. This essentially separates the network & system admin roles so that each person concentrates on their area of expertise.
Port-profiles are also available on standalone N5k/N7k to be used at interface templates when not integrating with VMware. -
Access Connections and Group Policy generated network profiles
Hello,
We are in the middle of rolling out 3500 T400 machines and are having fits with Access Connections 5.02. We have a default in-house Preferred Wireless Network Profile that is created on each machine via Group Policy. This works fine with AC and everything does what is supposed to do when our users are in our buildings. When our users go offsite, we have nothing but fits with AC and trying to set up any other WAN connections.
If users set up a new network connection, we are asking them to set it up thru AC. We have had them try using both the "Use Windows to Configure Wireless Network" as well as "IEEE 802.1X Authentication". Once the network connection is set up, for some, the wireless will work for a short period (a week or so) and then will no longer detect network connections. The user nor the client site has made any changes to the wireless configuration.
Others will have a stable connection wirelessly until they connect over VPN – VPN will drop in a few minutes after connection. They can then sometimes reconnect after a reboot; but the instability is a constant problem.
It seems to me that the problem could all be traced back to GP enforcement, which occurs every 8 hours when connected to our network. If a user is offline for several days, then connects up to check email or transfer time or whatever, then they are kicked off. If a user connects via VPN, they are kicked off within minutes - again potentially traceable to GP enforcement.
Has anyone else dealt with this scenario of Preferred Wireless Network policies and Access Connections?
Thanks!Try going back to AC 4.52, which solved the problems i was having with AC5.02 (freezes, BSOD, loss of wireless connections when coming out of standby, GUI problems) on Vista Home Premium. Scroll down for prevous versions of AC5.02 here:
http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-67283
I do not use a VPN system so AC4.52 may not help your 3500 Thinkpads.
Lenovo (Mark_Lenovo) knows there are problems with AC5.02 for the last three (or more ) months and have stated that AC 5.1 will solve the problems, but it has not been released as far as I know. There are many threads on AC5.02 on this forum and also on thinkpads.com
the Lenovo Blog site also has an update on AC5.02 ;under "Design Matters" on how they selected the graphics for wireless connections - the responses there offer some suggestions to fix the problems.

Bringing JAVA DI down gracefully
Hi All,
We have 10 JAVA dialog instance on our landscape.
Currently, if we need to bring down a DI for maintenance, we are just using stopsap j2ee and bringing the DI down and giving it for maintenance. Currently no logon groups configured on JAVA instances. If some sessions are running, it is cancelled.
what is the best way to bring Dialog instance down for maintenance work for example os patching , os upgrade without impact users ?
Thanks!Hi,
Another way of bringing down the Java (irrespective or whether it is add-in or standalone)
is by using jcmon .
The following is the command to start the jcmon command
go to the profiles directory.
Then use the command
jcmon pf=<instance profile>
u'll get 4 options.
select the 10 for cluster administration.
Then you wud get many options.
Select the option 10 which says shutdown instance.
Inorder to see the status whether it has shut down or not select 21 (process administration menu).
If there r more than 1 instance running on that machine it would show the list of instances that are up and running.
Select the index number for which you want to see the status.
Then you would finally see the status of each of the processes.
