Specify DNS for network interface

Hello
Please help me to specify name server for one network interface. Can't use resolv.conf because it's automatically rewrited by pppd script which establish connection with pppoe provider.
Here is the diagram.
There's a local zone maintained by local dns. It would be great if you helped me to configure eth0 to use local dns for only queries to local zone.
Sorry for my bad english.

scanning the manpage, this jumps up:
usepeerdns
Ask the peer for up to 2 DNS server addresses. The addresses supplied by the peer (if any) are passed to the /etc/ppp/ip-up script in the environment variables DNS1 and DNS2, and the environment variable USEPEERDNS will be set to 1. In addition, pppd will create an /var/run/ppp/resolv.conf file containing one or two nameserver lines with the address(es) supplied by the peer.
check if you have userpeerdns in your configuration file, this options makes ppp overwrite /etc/resolv.conf

Servermgrd: Where to specify DNS for server?

Been having a lot of trouble with Mac OS X Server 10.4.11 (running on PowerMac G5, 2 GHz, 2.5 Gb of RAM) the last few days. Some recurring log items I see are:
Jun 26 07:40:55 GBG-Server servermgrd: servermgr_dns: no name available via DNS for 172.16.1.64
Jun 26 07:40:55 GBG-Server servermgrd: servermgr_dns: no reverse DNS entry for server, various services may not function properly
I am not using the DNS service within OS X Server, it's a standalone that hosts a few databases and afp:// file sharing. Where does a person specify the "DNS" referred to in the log entries above??

Hi
Leif is absolutely correct in what he says, however if all you want the Server to do is host AFP and/or SMB shares you don't need internal DNS services. Admittedly things do work better with them but if you can ignore the warnings in the log it should not affect anything.
If the Server is supposed to be or may want to be an OD Master then you really must address the problem otherwise you don't really have an LDAP Server and it will cause you problems.
If you are not having any problems and things are working as they should be, ignore the logs and leave things as they are. Think of it a bit like going out on a sunny day and being warned by everyone you meet that it may rain later on and to take an umbrella with you. Not a great analogy I know but you get the point?

DHCP server admin - no network interfaces to choose from

When I first installed OSX server I was able to create a DHCP subnet range and my clients are still connecting to the server and working fine. Now if I go to edit my subnet range, nothing shows up under subnets. Also, if I attempt to add a subnet, the selection menu for Network Interface shows no interfaces. Both en0 and en1 are working properly otherwise. Any thoughts?

In Network Preferences -> Show: Network Port Configurations, are the network ports ticked?

Please!!!Some body help me solve this problem(except format my computer),i really really need your advice.

Hi huydaibang,
The older version SQL Server 2005 could be installed with SQL Server 2008 R2 side-by-side. It could not be the problem.
The reason that we get this error message is the client stack could not receive SSRP response UDP packet from SQL Browser.
Here are the steps:
1) Make sure your server name is correct, e.g., no typo on the name.
2) Make sure your instance name is correct and there is actually such an instance on your target machine.
3) Make sure the server machine is reachable, e.g, DNS can be resolve correctly, you are able to ping the server (not always true).
4) Make sure SQL Browser service is running on the server.
5) If firewall is enabled on the server, you need to put sqlbrowser.exe and/or UDP port 1434 into exception.
For more information, please refer to

How to set up with cacheing DNS for local network?

Our new Lion Server has a static IP Address pointed to over the internet by our registrar's zone file. Planning the Lion Server installation process with the intent of hosting Web, Mail and Open Directory services to a small number of users who are nearly all located off-site. I do also want Lion Server to be a caching DNS Server and DHCP authority on the local network to replace what dnsmasq does on our current Linux server.
I am looking forward to offloading some of the lower level Linux administration tasks and putting myself in the hands of the Lion Server Setup Assistant and Server App :-) but at the same time don't understand some of its assumptions and fear having to spend a lot of time experimenting and re-installing.
So, specifically, I want the Server App to know that my Lion Server has a "Host Name for the Internet" but that the DNS it sets up will not be the DNS for my zone - I will be managing that through my registrar's interfaces.
Second problem is my fnot understanding what name space devices on the local network will / should use. e.g. The Linux server will be available for backups etc on the local intranet (and optionally have a static ip address on the Internet) but MacBooks, PCs, iPads and iPhones will be served ip addresses by the Lion Server's DHCP. So will / should these dynamic devices have their machine names fully qualified by our domain name with RFC 1918 style ip addresses or something like .local? How do I tell this to Lion's Server App / Setup Assistant? How easy is it to update these initial settings later?

You do indeed need to have a master zone on lion server. There's no way to get around that since Open Directory depends on Kerberos and Kerberos depends on the DNS. LS scripts may see that the rDNS record exists, but I highly doubt that it'll auto configure everything for you... and given the number of possible variables, I bet that even if it worked something would need additional tweaking.
Sounds like an interesting lab excersize. You should try it on a test server!
Again... you just need to folow the set up procedure that Lion Server presents you with.
It won't be smart enough to see your external records and use them to configure a key distribution center for your OD.
As far as your caching needs... Could you set up your DHCP server to set the DNS server setting to show your internal server as the first hit, and your external as the second? That way when the client requests a resolution it'll not get a hit on your local server but will from the external?
The question then is how long will it wait for a response from the first server? Or will the first server respond with "I don't know" sending the client immediately to the second.
The server set up that I have works similarly. I have an internal master DNS that is replicated to a secondary. The first DNS has an A record (community.server.com) that points to the INTERNAL ip address of the secondary server that's also running the web service. The first server is running DHCP. It tells the clients to use the first and second servers as it's DNS lookup.
Now... Externally, my registrar hosts an A record for community.server.com that points to the external IP address of my router which then forwards the request to the proper port on the internal network.
This way, the local clients internally look up and get a response locally when they go for community.server.com. Externally, clients that look up community.server.com get the external connection to the router in my school.
Yikes... I fear that this is as clear as mud!

How to specify one ethernet port for network home directories (other for normal filesharing)?

So I'm trying to get Home Directories up and running on a 10.6.8 Xserve (waiting until I get my NFS sharepoints migrated to a Linux server [for other reasons] before moving up to 10.7 Server). But posting here since that will be happening in the next few weeks, and it might be applicable now (so I can at least get that resolved ahead of time).
I have a different DNS entry for each ethernet port: server.office.domain.com at 192.168.0.11 for the first, and homes.services.internal at 192.168.0.10 for the second. DNS lookups for both resolve correctly (as does the reverse lookup).
If I use the Server Admin to pick a sharepoint as an automount for Home Directories, everything is fine, but it picks the server.office.domain.com hostname. Picking that works just fine, but that is also the connection that feeds the filesharing. I'd prefer to split that home directory traffic out onto the second ethernet port. So I tried just duplicating the initial connection (since it can't be edited directly in Workgroup Manager) and changing the hostname to the internal one, but I get an error when attempting to log in (the client login screen gives a very helpful "Couldn't login because of an error" error message) and don't see anything in the server logs.
The client machine shows the following line:
Code:
10/20/12 5:27:42.688 PM authorizationhost: ERROR | -[HomeDirMounter mountNetworkHomeWithURL:attributes:dirPath:username:] |
PremountHomeDirectoryWithAuthentication( url=afp://homes.services.internal/Users,
homedir=/Network/Servers/homes.services.internal/Volumes/HomeDirectories/Users/ user123, name=user123 ) returned 45
(added line breaks so it didn't extend off the page)
So it looks like this is failing because the automount isn't in place, but I'm not sure how to work that out either (i.e. how do I add that making sure it uses the internal hostname?).
Any suggestions on getting this to work?
I realize one solution is just to LACP the two ports, but that is a different ball of wax (I may do that later if I get a 4 port ethernet card and performance limitations demand it).

A possible solution might be this.
On ADSLBOX and CABLEBOX configure different subnets for the LAN, e.g.
ADSLBOX: 192.168.1.0/24
CABLEBOX: 192.168.2.0/24
The MEDIABOX gets these static IPs:
ADSL-LAN: 192.168.1.2
CABLE-LAN: 192.168.2.2
On the MEDIABOX, configure the two network interfaces using two routing tables.
The ADSL-LAN routing table
ip route add 192.168.1.0/24 dev eth0 src 192.168.1.2 table 1
ip route add default via 192.168.1.1 table 1
The CABLE-LAN routing table
ip route add 192.168.2.0/24 dev eth1 src 192.168.2.2 table 2
ip route add default via 192.168.2.1 table 2
The main routing table
ip route add 192.168.1.0/24 dev eth0 src 192.168.1.2
ip route add 192.168.2.0/24 dev eth1 src 192.168.2.2
# use the CABLE-LAN gateway as default, so general internet traffic from MEDIABOX runs over CABLEBOX
ip route add default via 192.168.2.1
define the lookup rules
ip rule add from 192.168.1.2 table 1
ip rule add from 192.168.2.2 table 2
To test the setup:
ip route show
ip route show table 1
ip route show table 2
I don't know how to persist something like this in ArchLinux using netctl. Might require to write a special systemd unit for it. Above is a working example from a RedHat box at my company.

2K8 - Best practice for setting the DNS server list on a DC/DNS server for an interface

We have been referencing the article
"DNS: DNS servers on <adapter name> should include their own IP addresses on their interface lists of DNS servers"
http://technet.microsoft.com/en-us/library/dd378900%28WS.10%29.aspx but there are some parts that are a bit confusing. In particular is this statement
"The inclusion of its own IP address in the list of DNS servers improves performance and increases availability of DNS servers. However, if the DNS server is also a domain
controller and it points only to itself for name resolution, it can become an island and fail to replicate with other domain controllers. For this reason, use caution when configuring the loopback address on an adapter if the server is also a domain controller.
The loopback address should be configured only as a secondary or tertiary DNS server on a domain controller.”
The paragraph switches from using the term "its own IP address" to "loopback" address. This is confusing becasuse technically they are not the same. Loppback addresses are 127.0.0.1 through 127.255.255.255. The resolution section then
goes on and adds the "loopback address" 127.0.0.1 to the list of DNS servers for each interface.
In the past we always setup DCs to use their own IP address as the primary DNS server, not 127.0.0.1. Based on my experience and reading the article I am under the impression we could use the following setup.
Primary DNS: Locally assigned IP of the DC (i.e. 192.168.1.5)
Secondary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Tertiary DNS: 127.0.0.1
I guess the secondary and tertiary addresses could be swapped based on the article. Is there a document that provides clearer guidance on how to setup the DNS server list properly on Windows 2008 R2 DC/DNS servers? I have seen some other discussions
that talk about the pros and cons of using another DC/DNS as the Primary. MS should have clear guidance on this somewhere.

Actually, my suggestion, which seems to be the mostly agreed method, is:
Primary DNS: Locally assigned IP of the DC (i.e. 192.168.1.5)
Secondary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Tertiary DNS: empty
The tertiary more than likely won't be hit, (besides it being superfluous and the list will reset back to the first one) due to the client side resolver algorithm time out process, as I mentioned earlier. Here's a full explanation on how
it works and why:
This article discusses:
WINS NetBIOS, Browser Service, Disabling NetBIOS, & Direct Hosted SMB (DirectSMB).
The DNS Client Side Resolver algorithm.
If one DC or DNS goes down, does a client logon to another DC?
DNS Forwarders Algorithm and multiple DNS addresses (if you've configured more than one forwarders)

I agree with this proposed solution as well:
Primary DNS: Locally assigned IP of the DC (i.e. 192.168.1.5)
Secondary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Tertiary DNS: empty
One thing to note, in this configuration the Best Practice Analyzer will throw the error:
The network adapter Local Area Connection 2 does not list the loopback IP address as a DNS server, or it is configured as the first entry.
Even if you add the loopback address as a Tertiary DNS address the error will still appear. The only way I've seen this error eliminated is to add the loopback address as the second entry in DNS, so:
Primary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Secondary DNS: 127.0.0.1
Tertiary DNS: empty
I'm not comfortable not having the local DC/DNS address listed so I'm going with the solution Ace offers.

Two Network Interfaces and DNS

Hi -
Sorry for asking what sounds like a simple question. I'm running 10.6.2 on and early 2009 Xserve.
I have two interfaces. One that I'm using for web traffic and the other for a SIP PBX that's running on the Xserve. I know how to point the the inbound traffic to the correct interface (web vs. SIP) through WAN to LAN rules (I have a separate pubic IP for each service), but how do tell a particular service to use that interface for outbound traffic?
Is this done by creating a machine name locally for that interface? When I do that, I notice that in server admin, that DNS name is linked to that IP. I have outbound rules that tie that LAN IP to external IP, but I just want to make sure the Xserve is sending out traffic on the correct interface.
Thanks!

Static routes likely won't help here - they're based on the destination IP address and you're not likely to know that for all possible incoming connections. In addition, it's entirely possible that the same client IP establishes a web and a SIP connection so now you're hosed - you're only going to use one destination-based route for that client address.
My first suggestion would be to simplify your network and run on a single public interface. What's your thinking behind using two interfaces here? Unless you have > 1gbps WAN link you're not going to saturate the link. Even if you do you could bond the two interfaces together to get a 2gbps link to your switch/router.
Then you use your firewall to manage the address translation based on port (port 80 -> WAN IP 1, 5060 -> WAN IP 2).
That said, Snow Leopard appears to support source-based routing where the default route is based on the source (i.e. server-side) IP address. This could solve your issue, but I can't confirm this since my network is architected to not use source-based routing so I haven't needed to look at that option.

Intermitten error - SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified

Problem: I have a 2 WFE & 1 App server in my SharePoint 2013 Enterprise Edition SharePoint farm. My WFE 2 and App servers connect all the time to the SQL Server using a SQL alias. My WFE1 server work 80% of the
time. It is setup exactly like WFE2 except periodically 1 web app/site collection will stop working and throw the following error:
"A network-related or instance-specific error occurred while establishing a
connection to SQL Server. The server was not found or was not accessible. Verify
that the instance name is correct and that SQL Server is configured to allow
remote connections. (provider: SQL Network Interfaces, error: 26 - Error
Locating Server/Instance Specified)"
When I log into WFE1 I can connect to SQL using the alias using a udl file and telnet to verify the SQL alias is connected.
Hypothesis/guess: It appears like WFE1 periodically looses networking but only for 1 specific site collection.
Any ideas are most welcome?

Hi Aries,
I can rule out SQL Server (AOAG) Always-on as the farm doesn't use it.
"max worker threads" is set to 512 with 4CPU's. Rule out.
From the log and looking at the breakdown of the SharePoint request, the request is hitting the WFE2 server which in turn is trying to connect to the content database. The connection string/instance is not available. In summary, I believe the
issue is WFE2 periodically cannot connect to the SQL instance. At the same time WFE1 is working so we know it isn't the SQL server. WFE1 & WFE 2 are on the same VLAN and both appear connected and can see the SQL database using a udl file.
WFE2 has other web applications that are working while the erring web site fails. An IIS reset fixes the issue and restarting the "App pool" for the offending IIS website also fixes the problem. This tells me the issue
is the IIS process. When it tries to connect to SQL /the content database it fails.
I already raised the ticket with MS , the engineer has been looking at it with me, we have tried to identify the issue and also looked at TCP Chimney offload being a possible issue. As my servers is Windows Server 2012, all the servers have the default
"TCP Chimney Offload" setting set to "disabled". WFE1, WFE2, APP1 and SQL have the same setting so this is not the issue. At least this has been ruled out.

http://blogs.msdn.com/b/psssql/archive/2008/10/01/windows-scalable-networking-pack-possible-performance-and-concurrency-impacts-to-sql-server-workloads.aspx
I will keep posting about the problem, hopefully MS support can escalate and the root cause can be determined.
"The bottleneck is on the WFE2 server process trying to communicate with SQL. SQL is up and listening. Only 1 of the website/WebApplication on WFE fail for 15-20 minutes while the other websites are fine."

CRS-5008: Invalid attribute value: ce0 for the network interface

Hi all,
we try to install grid infrastructure 11GR2 (11.2.0.1) into Solaris Zone with shared network interface.
We also modified scirpt racgvip, so it will be able to login (via ssh with key authorization) to the global zone and add or remove interface on zone. Script itself works fine.
But it seems that orarootagent some how checks the interface, and returned error.

Does anybody know how the orarootagent checks for the network resource?
It seems that there are some procedures (NetworkAgent::checkLink, NetInterface::sGetIpAddress) inside it. But the problem is that this file is binary.
Or may be there are some ways to track how orarootagent checks?

How can I log the byte count for a network interface

I'd like to track/log the number bytes transmitted and received on a network interface. The end result is to give daily and or monthly usage counts.
How can I do that?

This software might do the trick. Not too expensive and it has a free trial.
It keeps logs of each time the program is run and you can configure it to run at system startup in the preferences window. If you go to the Tools menu and choose Traffic Log the calculator can let you specify time frames. Might be what you need!

How do I get ipackets and opackets statistics for logical network interface

I do a kstat_lookup() and kstat_read() to get the ipackets and opackets statisti
for the physical network interfaces like hme0.
However those statistics are not available via kstat for logical interfaces such
as hme0:1.
I notice that netstat -ai reports numbers for ipackets and opackets for
logical network interfaces so that information must be available
programatically but where?

netstat(1M) uses private ioctl(2) calls to a prepared /dev/arp to extract SNMP MIBs
that contain this information. I agree that it should be published via the kstat interfaces
as well.
