Change parameters on network interface card

Hi,
Ndd utility says that my ce0 adv_100fdx_cap, adv_100hdx_cap, adv_10fdx_cap, adv_10hdx_cap are read only. Can I set these capabilities to read write??? I'll get a permission denied message, if I try "ndd -set /dev/ce0 adv_100fdx_cap 1" in superuser. My goal is to force NIC to work at 100Mbps with full-duplex operation.
Best regards,

Hello,
No, you cannot change the "cap" value. That is fixed, as it is the "CAPability" of the card's driver. Hence read only. What you can change is the "adv_cap .. " params, in other words, what the card is "ADVertising" for capabilities.
Some folks still use a startup script, but this changes the interface settings long after the card is initialized (since it has to wait for init to run). A bad idea if you are using IPMP or other processes that want the interfaces setup from the kernel.
The other method is to setup ce.conf. You will need pathing info from /etc/path_to_inst to construct the proper syntax for that file. i don't recall that file exists by default, but you have to create it.
Not using auto_negotiation is a very bad idea and I don't recommend that. I've sat through waaaay too many confcalls with waaaay too many people to sort through and explain the problems that fixing interface speed/duplex causes. I will bear those scars forever. So that is all I wish to say on this matter : )
FWIW!

Change Open Directory Network Interface

I have a Mac Mini running Snow Leopard Server. This machine has two ethernet interfaces (internal and USB one). I'd like to restrict Open Directory/LDAP to run on ONLY ONE of the NICs, leaving the ports used by Open Directory/LDAP free on the other NIC. I seem to be unable to locate the necessary preference or configuration file to make this change. I am hoping someone on the forum knows how to accomplish this. Thank you in advance!

Network interface cards tested with cisco agent desktop and CTI Toolkit Desktop Silent Monitor

Hi Guys,
My Customer is testing the Silent Monitoring, but, not is working. He is using the NIC Intel 82579LM, version 17.4 - 64 bits. I read the documentation the link http://www.cisco.com/en/US/prod/voicesw/custcosw/ps5693/ps14/prod_system_requirements0900aecd800e3149.pdf
but, the reference is to version 7.1.3. My Customer work with UCCX and CUCM version 8.6. Are there one specific documentation about this version? The link don´t show the NIC tested by my Customer
Thank You,
Best Regards,
Wilson

Hi
I've done lots of deployments of this on UCCX, and still haven't found a NIC that doesn't work. I'm sure there are some, but they appear to be very rare.
If you can sniff the UDP when a call is in progress, it can work. If you can't, then it's usually down to configuration - e.g. non-phone-connected PCs, span-to-PC-port, PC vvvlan access, etc etc.

What is a network interface card?

A prospective broadband/cable supplier says I need this installed. Does the straight-out-of-the-box Intel iMac have this? And if so, is it possible to say – given the limited information I can offer – whether I can still connect using my existing ethernet modem?

Hi Cheapster,
Does the straight-out-of-the-box Intel iMac have this?
Yup. At the rear of your iMac you will see the ethernet port.
And if so, is it possible to say – given the limited information I can offer – whether I can still connect using my existing ethernet modem?
Most definitely. Just plug one end of the ethernet cable to the ethernet port at the rear of your iMac and the other end to the ethernet modem (adsl router/modem). You'll also have another cable that goes from the adsl router to your phone line socket via a microswitch.

Configure Network (Ethernet Cards) interfaces doubts.

Hi All,
I m beginner in Solaris/Unix, and I have same problems in configure my network.
I have one machine with 2 Ethernet Cards, this machine has multiboot, than it have Solaris 10 and Windows XP.
I will show the configuration that I have on Window,I need the same configuration in Solaris:
In eth0:
IP: 192.168.0.117 (In Solaris the name of this is in ifconfig is IP, OK?)
Mask: 255.255.255.0 (In Solaris the name of this is in ifconfig is
netmaks , OK?)
Gatway: 192.168.0.254 (In Solaris the name of this is in ifconfig broadcast, OK?)
Primary DNS: 192.168.0.254 (In Solaris I don�t know how configure this)
Secondary DNS: void (In Solaris I don�t know how configure this)
I Have an DHCP Server in 192.168.0.254, than I can use dhcp.
The problems, When I try use DHCP:
Ifconfg eth0 DHCP
This command delay and return an Error.
If Itry configure manually, like
Ifconfg eth0 192.168.0.117 (this OK)
Ifconfg eth0 netmask 255.255.255.0 (this OK)
Ifconfg eth0 broadcast 192.168.0.254 (here the 254 is changed to 255 that is broadcast default, but in my net broad cast or router is in 254)
Other thing how I save this configuration. When I restart I lost all changes�
Well in second interface the problem is same, but I didn�t have DHCP:
IP: 200.44.136.145 (In Solaris the name of this is in ifconfig is IP, OK?)
Mask: 255.255.255.192 (In Solaris the name of this is in ifconfig is netmaks , OK?)
Gatway: 200.44.136.129 (In Solaris the name of this is in ifconfig broadcast, OK?)
Primary DNS: 4.2.2.2 (In Solaris I don�t know how configure this)
Secondary DNS: void (In Solaris I don�t know how configure this)
fconfg eth1 200.44.136.145 (here .44 is changed to 36)
Any one can help-me please?
Thanks

yes. you got it .... eg..
/etc/hostname.le0
/etc/hostname.le1
in here put the hostname ... so at the shell prompt:
# hostname <cr>
should give your hostname.
now, in the hosts file: eg:
# Internet host table
127.0.0.1 localhost
<your ip address> <your hostname> loghost
129.156.89.252 host2
you need to reboot after this.
if you get a 'bad address' error on boot,
you probably have a mismatch of hostnames/ip addresses somewhere in their respective files.
also, see:
# man hosts
# man ifconfig

[SOLVED] Network interface name keeps changing

My network interface name keeps changing between wlp2s0 and wlan0. This is a real pain, since I never know what name will be generated at boot. Most of the time it's called wlp2s0, so this is what netctl is set up to handle by itself. At boots were wlan0 is generated I have to connect manually.
I've tried making the name static by adding a rule to the /etc/udev/rules.d/10-network.rules. The rule i added was:
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="48:5d:60:7e:64:e9", NAME="wlp2s0"
Wlp2s0 is generated at boot alright, but I still have to connect manually with this solution. As if the "new" wlp2s0 is not recognized as the old one (same MAC). What gives?
This is on an Asus Eee 1001PXD, with the Qualcomm Atheros AR9285.

I've now been able to replicate the issue, and run the command:
journalctl -b
I did find the output:
mai 18 02:30:02 <hostname> systemd-udevd[126]: error changing net interface name wlan0 to wlp2s0: Device or resource busy
I haven't been able to process the whole output yet (I'll continue tomorrow if necessary), but I've found some things that I hope will clearify things. I get similar outputs to the following a lot throughout:
mai 18 02:30:03 <hostname> dhcpcd[237]: wlan0: carrier lost
mai 18 02:30:03 <hostname> dhcpcd[237]: wlan0: waiting for carrier

mai 18 02:30:04 <hostname> systemd[1]: Starting Network.
mai 18 02:30:04 <hostname> systemd[1]: Reached target Network.
EDIT:
I see now that this is later in time, so that's not so strange after all. I'll look some more.
EDIT2:
The error code that a name change i impossible is the first time the term 'wlan0' occurs in the log. However there's a line much earlier that talks about wlp2s0:
mai 18 02:29:59 <hostname> systemd[1]: Expecting device sys-subsystem-net-devices-wlp2s0.device...
But as I said, if this information doesn't help, I'll have a closer look at the output tomorrow. Getting late here in Norway now.

Changing a Network Interface in DAG Replication Network after going P2V

I have a DAG member suffering severe hardware failure so I have gone P2V with it. It's functioning fine, except that the DAG Network Interfaces have changed - The MAPI Interface was on "Local Area Network" on the physical server, and is now
on Local Area Connection 7 on the VM. However, the DAG settings still point to "Local Area Network" and will not let me change it. Same thing for the replication network.
I have lost redundancy due to this, so I need to get it repaired pretty promptly.
Removing and re-adding the subnet in the DAG network has no effect - it still references the old physical NIC instead of the new virtual NIC, despite the new virtual NIC having the same IP as the old physical NIC.

Try to change the network binding on the server
http://technet.microsoft.com/en-us/library/cc732472(WS.10).aspx
Try to delete the hidden network adapters as well.
Open Device Manager, from the File menu, expand the View and select the Show Hidden Devices option. This will enable and show any old un-used devices in the window

PRIF-33 and CRS-02307 while changing public network interface, RAC

Hi,
I'm working on an Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production With the Partitioning, Real Application Clusters, Automatic Storage Management. It's a 3 nodes RAC: mgvdb01/02/03
After the installation I had to change IP (different IP and Subnet) to the RAC:
From 172.17.1.0/24 to 10.19.201.0/24.
Node from 172.17.1.31/32/33 to 10.19.201.31/32/33.
The same for VIP(s): from 172.17.1.131/132/133 to 10.19.201.131/132/133.
The oifcfg iflist shows correct ips configuration:

I'm following doc 276434.1 from Metalink: How to Modify Public Network Information including VIP in Oracle Clusterware, starting from Case III "Changing public network interface, subnet or netmask".
But at the first operation I've a problem:

[Solved] Network interfaces change places after every reboot.

This has been bugging me for a while, it seems that in Arch every time the system reboots, the network interfaces are recognized in a random order.
So what was eth0 in the last reboot will be eth1 in this reboot, and sometimes it will remain for several reboots and then flip again.
This does not occur in Fedora on the same machine ever.., does any one know how to work around this problem?

[solved] network interface names changed?

Hi,
I reinstalled arch on my laptop yesterday (hard drive failure). Normally, not to big a deal. Took me four hours to get arch installed. Why? couldn't for the life of me figure out how to get the wireless connected (ethernet connection unavailable, port is physically damaged). In the end, my fault, I should have tried iwconfig earlier.
It seems that my network interfaces have all changed names since the last time i installed. The wireless interface has changed from the sensible 'wlan0' to the mystical 'wlp4s0'.
also, eth0 is now enp9s0.
This has messed up a number of my scripts and above all is more than a little confusing, wlan0 feels right, wlp4s0 feels wrong.
Now, I'm not opposed to change. I like change, even if it breaks a lot of my scripts, but I like to know why something has changed to something less intuitive.
Why was this change put in place? I can't find any real info on it after 30 mins googling.
Can it be changed back through some setting somewhere without upsetting whatever problem it's supposed to fix?

Binding a Second IP to an Interface Card

Hey All,
I need to bind a second IP address to my single network card on a Solaris 7 server. I've done this in Linux by adding an additional ifcfg-eth0 file to /etc/sysconfig/network-scripts, specifying the new IP address. With Solaris though, the new landscape has me a bit flustered. I'd very much appreciate a guide through the woods here, my flashlight is going dim...
Much Appreciated,
Chris

Hi Chris,
Here's a write up on this question:
Virtual Interfaces (One interface, different IPs):
Solaris TCP/IP allows multiple logical interfaces to be associated with a physical network interface. This allows a single machine to be
assigned multiple IP addresses, even though it may have only one
network interface. (see the ifconfig man page)
You can define up to 255 "logical addresses" for a given network interface on Solaris 2.x.
There is no supported method to do so on SunOS 4.1.X (Solaris 1.x)
In Solaris 2.6 you can go greater than 256 ( 0-255 ) which is configurable with NDD. The command "ndd -set /dev/ip ip_addrs_per_if 1-8192" will permit you to configure as many as your addressing structure will permit
(up to 8191 virtual hosts.)
1. Create an entry in the /etc/hosts file ( or nis host map) for each of the virtual interfaces with the hostname and IP address you want to use. Don't forget to add the hostname to /etc/hosts NIS, NIS+, and/or DNS database.
2. Create a /etc/hostname.<interface:#> file for each of the interfaces. (/etc/hostname.le0:1, hostname.le0:2, hostname.le0:3...le0:255.)
The file can contain a single line with either the ip number or hostname reference. For example, if you are using the le0 interfaces, you would create the following files:
/etc/hostname.le0:1 (do NOT use a le0:0 - same as le0 )
/etc/hostname.le0:2
and so on
This can also be done for an hme interface. You can have up to 1024 virtual interfaces under 2.5.1 This file should include the hostname or IP address for the corresponding interface.
3. If subnetting is being used, there should be an entry in the
/etc/netmasks file in the following format:
network_address netmask
The network_address should be the network address before
subnetting. For example, a class B network that is subnetted to
a Class C would have an entry such as:
157.145.0.0 255.255.255.0
4. Reboot the system
5. Verify changes with an ifconfig -a
Note: there are some bugs with third party applications/daemons that do not operate well with many virtual interfaces.
Additional Note: For Security and network isolation. You can set ip_forwarding off and ip_strict_dst_multihoming on, if you are trying to prevent access to the other interfaces.
"ndd /dev/ip ip_forwarding" Determines if the workstation will route packets.
"ndd /dev/ip ip_strict_dst_multihoming" Determines whether to use Strict Destination Multihoming. If this variable is set to True, and ip_forwarding is turned off, then the machine will not except packets destined for a different interface. RFC112
If duplicate additional local routes are added (by ifconfig) when the virtual interfaces are on same subnet, then you may need to "route delete net" on these.
A /etc/rc2.d/S99vif file can be added to ifconfig and add/delete routes, etc.
On 2.6 it may be neccessary to turn off interface groups.
To disable this feature (which is on by default) the following line
must be added to /etc/rc2.d/S69inet
ndd -set /dev/ip ip_enable_group_ifs 0
Thanks
