Designing DHCP agent redundancy

Hi all.
I am using a router to act like a relay agent between a dhcp server and a cpe. This is done to provide voip service (SIP) to customers. There are multiple unnumbered interfaces(one per site) which use as a gateway interface, a specific loopback. The current config looks like that:
interface GigabitEthernet0/0/2.xxxxx
encapsulation dot1Q xxxx second-dot1q xxxx
ip vrf forwarding xxxxxxx
ip dhcp relay information trusted
ip unnumbered Loopback350012011
ip helper-address xx.xxx.xxx.xx
Since i have a second router of a similar operating function i am trying to find a way to make this service redundant. The two routers are connected to a single switch from which they receive the traffic from the cpes.
One problem is to redirect the user to a "mirror" interface of the second router if the first one fails. However Hsrp cannot be configured as far as i know to ip unnumbered interfaces.
The second problem that is pretty clear is that even if this could be done the second router would not have the appropriate info so as to route the CPE.
When the relay agent(router 1) is operating as an intermediate of the client/server communication, it creates the appropriate static route for as long as the lease time lasts. So the second agent(router) that doesnt take part in this would have no way to hanndle an already given ip of a connected cpe. It would need to wait untill the leased time exprires and the cpe reconnects to the second router.
I have done some research but havent found any example like this. Are there any ideas on how would that be possible?

So, should my management console connect to each agent running ?
If I understand correct, the manager connects to one address only - the
cluster's. Then each agent on a node can give the information for the whole
cluster. Is this correct ?
If not, it could be not so easy to accomplish. The management should know
how to connect to several agents and then sum up the information, or I need
to put a master-agent.
I need to know that because we have also our private snmp agent running and
have to decide how use it within a cluster.
Thanks.

Hi.
I would like to know what is the appropriate usage of the snmp agentwithin
a multi-cluster WLS. Should I start one agent for all servers, or one
per
cluster, or should every server need its one agent ?
If I start one agent per cluster, and the server on which the agent is
running goes down, how can the cluster be managed ?
Thanks,
Eran.

What is the best design to connect redundant Firewalls to redundant switches?

Hi All,
I would like to know the best possible design to connect redundant Firewalls(Netscreen,FortiGate etc) to redundant switches.I have dealt with Cisco FWSM's in which both the Firewall and switch is in the same chassis. So for the Vlan's behind the Firewall, we just create the L3 interface on the fwsm and do a static route in the switch. The Gateway IP will be tied to the primary fwsm and the failover happens through the network. But now i need to know the best possible design when i am connecting to a different vendor firewall.
Let's say i have 5 vlans and all these vlan's are behind the Firewall. The redundant switches will have the L2 vlan's created and have a static route to the Firewall. I am proposing the attached design in which i will have L2 vlan's created on the switch and L3 on the Firewall. The Firewall's and the switch will be connected with one trunk port and an access port for uplink and downlink traffic. The two switches will be connected each other using a vlan trunk.The two firewalls will be connected using a redundancy vlan.
I am not so sure about the working of other firewalls such as Netscreen and FortiGate. I am also confused with the traffic path that the frames will take by having this design.Please advice if you have any suggestions.
Appreciate your help and advice.
regards
dathan

To be honest, I don't understand how the Linux bonding mode can work without anything configured the other end.
My understanding of 'bonding' comes from Multilink PPP (MLP) where the data stream is chopped up and split across two (or more) circuits. At the other end, a similar MLP-enabled device reforms the data stream from the multiple circuits, maintaining packet order. But this requires MLP-enabled 'bonding' devices at each end.
Perhaps you could help me better understand the Linux bonding...

If the firewalls operate in the same fashion as Cisco ASAs, then the inter-firewall link doesn't carry traffic. It's for failover detection and HTTP replication only. But like I said, I'm not familiar with this vendor's products.

Same as above.

Grid control design and agent deployment

To give you a brief overview of the setup here, it is currently an agent per instance instead of an agent per host. This was done to allow an agent to be moved along with an instance to another host in a cluster (we are using IBM AIX LPAR, and Sun Clustering) thereby allowing a seamless transition between hosts and history retention for the instance. We would like to change this to an agent per host, however, we need to keep the historical information of the instance should it change hosts. So my questions are:
1. Is it possible using some sort of script or process to have an instance/target move between hosts and retain its previous historical information?
2. Is it possible to have a single, summarized availability report for all instances? The report per instance works, however, doing a single summary report for all instances does not display the correct information (it only shows PIT, i.e. the current state of the instances not historical over x period of time).
Any help is appreciated.
Thanks.

Let me provide some details as to the environment as to the deployment which I am doing in a HA environment:
- There is a physical 'myhost1' with virtual hosts names oradev1, oratst1. Note I am not referring to virtual machines, just virtual host names, or virtual IP.
- Each VIP hosts a listener and database instance. For example, oradev1 -> lsnr-oradev1 + orad1, and oratst1 -> lsnr-oratst1 + orat1
In this design each database and listener can be moved to another physical host separate from the other, say the entire oradev1 stack moves to 'myhost2'.
How would the agents be deployed in such a design? I think an agent per physical host, with the VIP used to monitor the virtual stacks, such has as each virtual host containing the listener and database instance. This way when a virtual stack moves we can just switch the agent monitoring that stack to the new host and retain the history of the targets.
Is my thinking correct? Is there a better way to retain the history when moving the virtual stacks perhaps doing an agent per instance instead of physical target?
I hope this provides more details. Thanks.

DHCP with redundant Gateway does not work

I am having trouble connecting to my office network using Wifi.
I have done some investigation and found the problem which is...
When DHCP server serves the request and replies with multiple/redundant gateways, the device does take the IP and communicates within the local network but ignores the gateway and is not able to connect the outside network.
When I requested my Systems Administrator and he added specific setting for my device's MAC address and sent only one gateway in DHCP reply, device starts to connect outside.
Our office has other debian based and CentOS based systems running including Ubuntu workstations but none of them is having problem with multiple/redundant gateways but only N900 is having this problem. It means that the problem is not inherited from Linux or Debian but the bug is related to Maemo itself.
I have tried to tell add some technical details and do not expect answers like to check firewall and so. This is a genuine problem and is not intermittent. We have experienced it using MS DHCP server under windows 2003 and win 2k as well.
End users: Please try to duplicate the problem before suggesting a work around or anything
Developers/Admins/Officials: I hope you acknowledge the problem soon.

Yes it is uncommon configuration in house holds but in offices or places that have access to more than one Internet connection the configuration will be common. Houses normally have one small router with one internet connection. However in many offices the router is attached to multiple connections and manages fault-tolerance. Having said all that, regardless of how often it is used, when used it wont work and it is a bug.
In DHCP protocol "003 Router" is defined as a list of IPs not a single IP and if DHCP protocol is properly supported this should have work. What I mean is that this problem is related to DHCP implementation. Following is the output of route command...

I already posted the big on Bugzilla
https://bugs.maemo.org/show_bug.cgi?id=9662
Well I posted this here as well so if someone else also faces the same problem (not sure if there will be one) but they should at-least know the problem instead of thinking that why the hell my internet does not work in office when there is no firewall blocking it.. :-)
I do hope to get it viewed by a "sympathetic developer" :-)
I currently am not into develop/modify scripts but if this is not fixed by others then I believe I don't have a choice.
For now as I mentioned I did a work around by adding an IP reservation in my DHCP server which allows me to fix it to one Gateway for this MAC address only. But if I did not have admin access over my DHCP server, I was in trouble then and maybe would not be able to event troubleshoot and identify the problem.

Single Server DHCP environment - redundancy question

I have a single 2012 R2 Server, running as Host. Host has Hyper-V services only. Single Guest, running Server 2012 R2, as Domain, FS, DHCP, DNS. Small shop, 20 workstations. IP served from DHCP to clients. If server dies, I
have no internet access. We have a point of sale system, must have credit card access. I will NOT have a second server for failover/split services (Budget will not allow. Please take note of that. We are a SMALL business. All
of our computers are lease refurbs and more than 4 years old. Additional hardware is not a solution).
I am going to move dhcp to router. It is small and cheap and I have a spare configured as a mirror of our production router. If my cheap but functional router dies, I can replace it in less than 60 seconds. If my server suffers failure,
I cannot replace it in 60 seconds.
I welcome other suggestions, or configuration changes of my network. We have had several physical infrastructure incidences over the last 18 months that have resulted in server failure, meaning we lack the access to the internet, meaning we cannot sell product,
meaning we do not make money to pay (my) salary. I understand ZERO down time comes at a cost. I'm trying to get the best reliability on the funds I have available.
Thanks

Thank you for not providing a single answer. WHY does moving DHCP from DC solve nothing? If server fails, workstations would still have access to internet, which allows my credit card processing, the problem I'm describing. So, what am
I missing that makes moving DHCP from the DC so bad?
How does a good backup solve my internet connection issue? I have a good backup system.
No, I cannot work out of the cloud. Our internet service would be jealous of a 56K dial-up modem.

Design for DHCP redundancy.

Hi,
Can somebody advice , how can i have dhcp server redundancy in my network. I need to design a network that will have around 30 vlans spanned across 50 buildings.

Hi Renzil,
I'm actually working on a similar solution at work at the moment. There are a couple of options (some have mentioned already)
1. Have two dhcp servers in different locations, with the same scopes and settings configured. Add the IP helper address for both servers to any device that needs to relay dhcp broadcasts. Then choose either;
a) Active/Standby - Configure the dhcp servers to act as a Primary/Secondary, by disabling all scopes on the secondary server until a situation arises where you need to failover. When you failover, enable the scopes on the secondary dhcp server. Be careful to prevent the Primary from giving lease when it comes back online.
b) Active/Active - Split the scopes across both dhcp servers in a 20/80 or 30/70 configuration as mentioned above. You will need to ensure the same reservations are configured on each dhcp server.
c) Active/Active - Disable some scopes on one of the servers, and have the same scopes active on the other server. When failover occurs, enable the scopes that are disabled on the server that is still reachable. Again be careful of the failed server issuing leases when it comes back online.
2. If you have the option, Windows Server 2008 Enterprise now offers High Availability Clustering for DHCP servers. This is a good solution because the DHCP database is shared between the two DHCP servers, so you don't need to worry about duplicate addresses being issued. This also works across geopgraphically dispersed sites, which is great if you have multiple data centres in different locations. You need to have a storage solution in place thatcan replicate the DHCP database to the failover location.

dns-server 8.8.8.8
default-router 192.168.42.1
How can I connect this DHCP service to the Dot11Radio0 interface or to the dot11 SSID??
Thanks

Configuring DHCP
WLANs can be configured to use the same or different Dynamic Host Configuration Protocol (DHCP) servers or no DHCP server. Two types of DHCP servers are available: internal and external.
Internal DHCP Server
The controllers contain an internal DHCP server. This server is typically used in branch offices that do not already have a DHCP server. The wireless network generally contains 10 access points or fewer, with the access points on the same IP subnet as the controller. The internal server provides DHCP addresses to wireless clients, direct-connect access points, appliance-mode access points on the management interface, and DHCP requests that are relayed from access points. Only lightweight access points are supported. When you want to use the internal DHCP server, you must set the management interface IP address of the controller as the DHCP server IP address.
DHCP option 43 is not supported on the internal server. Therefore, the access point must use an alternative method to locate the management interface IP address of the controller, such as local subnet broadcast, DNS, priming, or over-the-air discovery.
Note See the Chapter 8 "Controlling Lightweight Access Points," or the Controller Deployment Guide at this URL for more information on how access points find controllers:
http://www.cisco.com/en/US/products/ps6366/prod_technical_reference_list.html
Note A internal DHCP server pool will only serve the wireless clients of that controller, not clients of other controllers. Also, internal DHCP server can only serve wireless clients and not wired clients.
Note DHCP required state can cause traffic to not be forwarded properly if a client is deauthenticated or removed. To overcome this, ensure that DHCP required state is always in disabled state.
External DHCP Servers
The operating system is designed to appear as a DHCP Relay to the network and as a DHCP server to clients with industry-standard external DHCP servers that support DHCP Relay, which means that each controller appears as a DHCP Relay agent to the DHCP server and as a DHCP server at the virtual IP address to wireless clients.
Because the controller captures the client IP address obtained from a DHCP server, it maintains the same IP address for that client during intra-controller, inter-controller, and inter-subnet client roaming.
DHCP Assignment
You can configure DHCP on a per-interface or per-WLAN basis. The preferred method is to use the primary DHCP server address assigned to a particular interface.
Per-Interface Assignment
You can assign DHCP servers for individual interfaces. The management interface, AP-manager interface, and dynamic interfaces can be configured for a primary and secondary DHCP server, and the service-port interface can be configured to enable or disable DHCP servers.
Note See the Chapter 10 "Managing Controller Software and Configurations," for information on configuring the controller's interfaces.
Per-WLAN Assignment
You can also define a DHCP server on a WLAN. This server will override the DHCP server address on the interface assigned to the WLAN.
Security Considerations
For enhanced security, we recommend that you require all clients to obtain their IP addresses from a DHCP server. To enforce this requirement, all WLANs can be configured with a DHCP Addr. Assignment Required setting, which disallows client static IP addresses. If DHCP Addr. Assignment Required is selected, clients must obtain an IP address via DHCP. Any client with a static IP address is not be allowed on the network. The controller monitors DHCP traffic because it acts as a DHCP proxy for the clients.
Note WLANs that support management over wireless must allow management (device-servicing) clients to obtain an IP address from a DHCP server. See the "Using Management over Wireless" section for instructions on configuring management over wireless.
If slightly less security is tolerable, you can create WLANs with DHCP Addr. Assignment Required disabled. Clients then have the option of using a static IP address or obtaining an IP address from a designated DHCP server.
Note DHCP Addr. Assignment Required is not supported for wired guest LANs.
You are also allowed to create separate WLANs with DHCP Addr. Assignment Required disabled; then define the primary / secondary DHCP server as 0.0.0.0 on the interface assigned to the WLAN. These WLANs drop all DHCP requests and force clients to use a static IP address. Note that these WLANs do not support management over wireless connections.
Note See Chapter 4 "Configuring Controller Settings," for instructions on globally configuring DHCP proxy.
Note If you want to specify a static IP address for an access point rather than having one assigned automatically by a DHCP server, see the "Configuring a Static IP Address on a Lightweight Access Point" section for more information.
This section provides both GUI and CLI instructions for configuring DHCP.
Using the GUI to Configure DHCP
To configure DHCP using the GUI, follow these steps:
Step 1 Follow the instructions in the "Using the GUI to Configure the Management, AP-Manager, Virtual, and Service-Port Interfaces" section or "Using the GUI to Configure Dynamic Interfaces" section to configure a primary DHCP server for a management, AP-manager, or dynamic interface that will be assigned to the WLAN.
Note When you want to use the internal DHCP server, you must set the management interface IP address of the controller as the DHCP server IP address.
Step 2 Choose WLANs to open the WLANs page.
Step 3 Click the ID number of the WLAN for which you wish to assign an interface. The WLANs > Edit (General) page appears.
Step 4 On the General tab, unselect the Status check box and click Apply to disable the WLAN.
Step 5 Re-click the ID number of the WLAN.
Step 6 On the General tab, choose the interface for which you configured a primary DHCP server to be used with this WLAN from the Interface drop-down list.
Step 7 Choose the Advanced tab to open the WLANs > Edit (Advanced) page.
Step 8 If you want to define a DHCP server on the WLAN that will override the DHCP server address on the interface assigned to the WLAN, select the DHCP Server Override check box and enter the IP address of the desired DHCP server in the DHCP Server IP Addr text box. The default value for the check box is disabled.
Note The preferred method for configuring DHCP is to use the primary DHCP address assigned to a particular interface instead of the DHCP server override.
Note DHCP Server override is applicable only for the default group.
Step 9 If you want to require all clients to obtain their IP addresses from a DHCP server, select the DHCP Addr. Assignment Required check box. When this feature is enabled, any client with a static IP address is not allowed on the network. The default value is disabled.
Note DHCP Addr. Assignment Required is not supported for wired guest LANs.
Step 10 Click Apply to commit your changes.
Step 11 On the General tab, select the Status check box and click Apply to reenable the WLAN.
Step 12 Click Save Configuration to save your changes.
Using the CLI to Configure DHCP
To configure DHCP using the CLI, follow these steps:
Step 1 Follow the instructions in the "Using the GUI to Configure the Management, AP-Manager, Virtual, and Service-Port Interfaces" section or "Using the GUI to Configure Dynamic Interfaces" section to configure a primary DHCP server for a management, AP-manager, or dynamic interface that will be assigned to the WLAN.
Step 2 Disable the WLAN by entering this command:
config wlan disable wlan_id
Step 3 Specify the interface for which you configured a primary DHCP server to be used with this WLAN by entering this command:
config wlan interface wlan_id interface_name
Step 4 If you want to define a DHCP server on the WLAN that will override the DHCP server address on the interface assigned to the WLAN, enter this command:
config wlan dhcp_server wlan_id dhcp_server_ip_address
Note The preferred method for configuring DHCP is to use the primary DHCP address assigned to a particular interface instead of the DHCP server override. If you enable the override, you can use the show wlan command to verify that the DHCP server has been assigned to the WLAN.
Step 5 Reenable the WLAN by entering this command:
config wlan enable wlan_id

How to attach agent with unusual AD and DNS setup?

I am trying to configure DPM for a client, which is a university department. They have a somewhat unusual setup of their AD and DNS and I think that is why I am having trouble attaching an agent I have installed.
It is a new installation of DPM 2012 R2 version 4.2.1292.0 with a local SQL Server 2012 SP2. The OS is Windows Server 2012 R2. It is going to protect a bunch of SQL Server databases all on the same Windows Server 2012 R2 server. The SQL Server is a physical
server and the DPM server is a hyper-v VM, running on a Windows Server 2012 R2 host.
The install of DPM itself went smoothly.
To install the agent on the SQL Server machine, I followed the instructions here:
https://technet.microsoft.com/en-us/library/hh758186.aspx#BKMK_Manual. This was successful (I think)
Then I proceeded with these instructions to attach the agent:
https://technet.microsoft.com/en-us/library/hh757916.aspx
This fails at the enter credentials stage with this message:
DPM could not connect to the service control manager on these servers: [SqlMachinename].win.[universityname].dk (ID: 33221)
As far as I can tell, the problem has to do with how the university manages windows AD domains and DNS lookup.
The university uses one common AD domain named win.[universityname].dk for the entire campus, but it looks like DNS names for individual windows machines is managed locally at individual departments.
Ipconfig says this (abbreviated) for the SQL Server where I installed the agent:
Host Name . . . . . . . . . . . . : [SqlMachinename]
Primary Dns Suffix . . . . . . . : win.[universityname].dk
DNS Suffix Search List. . . . . . : win.[universityname].dk
[departmentname].[universityname].dk
Ethernet adapter T2:
Connection-specific DNS Suffix . : [departmentname].[universityname].dk
DHCP Enabled. . . . . . . . . . . : Yes
This works from the DPM machine and shows the correct IP:
ping [SqlMachinename]
This works from the DPM machine and shows the correct IP:
ping [SqlMachinename].[departmentname].[universityname].dk
This fails from the DPM machine ("could not find host") and does not get an IP:
ping [SqlMachinename].win.[universityname].dk
I've used Message Analyzer to verify that when pinging just [SqlMachinename], in fact DNS tries first to append win.[universityname].dk, which fails and second [departmentname].[universityname].dk, which then succeeds. This is by the book, as I understand
it because of the DNS Suffix Search list or because of the connections-specific DNS Suffix.
The problem is that DPM only tries [SqlMachinename].win.[universityname].dk. I have verified this with Message Analyzer.
I am not sure how to proceed. Is there another way to attach the agent? Maybe by IP-address?
I cannot ask the client to put [SqlMachinename].win.[universityname].dk in their DNS database. I am sure that they do not register any individual machines in that DNS domain which cuts across the entire campus. I am equally sure that they will not consider
creating individual AD domains for each department just because I ask (although that would probably be best in the long run).
Any suggestions would be very much appreciated.

Found a workaround:
I can install and attach the agent using one of the methods designed for agents in workgroups or untrusted domains. For me NTLM worked fine as long as I used simple nertbios computer names without any domain suffixes.
This is what worked:
On protected server:
SetDpmServer.exe -dpmServerName DPMServername -isNonDomainServer -userName DpmNtlmAccount
On DPM Server:
Attach-NonDomainServer.ps1 -DPMServername DpmServername -PSName servername -Username DpmNtlmAccount -Password xxxxx
I still think it is weird that DPM insist that protected servers in thewe same AD domain must use the AD domain name in their DNS name. Very inflexible.

Need advice for future design and hardware I should purchase now.

I was wondering if someone could assist me in making a decision on where I should take the future design of my network. Currently the design has no redundancy and I've been told recently that my company has a bit of money to spend and that it needs to spend it within the next 2 weeks. I am fairly new to the company so haven't been able to really think about future redundant designs nor have I studied much about designing networks. There are about 200-300 people that may be using my network at once, all users aren't at the location in question but they may be asking for resources from our servers.
I've included a basic design of the "core" of my network and would like any suggestions for creating redundancy in the future and also optimizing the way data travels to our servers. Do people generally have redundant Layer 3 switches for the core in small networks such as mine? I will be replacing the 2811 since it only has 100Mbps connections and was thinking, perhaps replace this with a Layer 3 switch with the plan to have another identical Layer 3 switch installed to offer redundancy in the future.
Also, would it be a good idea to move the servers into a vlan on the core? Thanks for any advice on what I should be purchasing now with plans for redundancy being implemented over a year. -Mark

40k Can go pretty quick depending on the scope. Your server farm especially should be dual-homed capable of surviving link, hardware, routing, and software failure.
It's going to be best practice your server farm be in it's logical subnet, so failover mechanism can be controlled routing protocols, as opposed to FHRP's such as HSRP/VRRP/GLBP. Especially since you adjust routing timers to sub-second convergence.
Budget will be the primary limitation (as it always it) but ideally dual 6500's running VSS and FWSM would be the ideal way. Data centers should be designed with high availability in mind, hence the need to 2x devices.
Depending on the size of the SAN/Virtual infrastructure Nexus might want to be considered but you will chew up 40k before you know it.
Also make sure the server farm is scaled properly. Your server farms should be oversubscribed in a much higher ratio compared to your access layer.

Timesheet for Graphic Designer

Hello People
(please be gentle with me, I'm not very experienced with time-sheets etc).
I'm a graphic designer, been made redundant, and after struggling to find a job I'm going freelance but I'm really struggling to use Numbers to create a timesheet. I don't have Excel and don't particularly want to use it, partly sue to cost but also because I don't like it.
I know there are apps out there I could use, but all of those I've looked at either charge or don't do exactly what I need.
As I'm just starting out I need to monitor my workload, the time spent against the time i quote so I can refine things and get my estimating accurate and also make sure I then bill for all the hours I do (when it comes to an hourly rate).
I don't really know how to create spreadsheets using Excel with Formulas and rules etc. So a mate did it for me, but using that sheet in Numbers isn't transferring properly. So we are looking at starting afresh using Numbers but the trouble is neither of us know it well enough to create what I need.
First I need a time sheet, to keep a record of how much time i spend on a particular Job. I'll try to explain (stay with me please!)
To start off I need in my time-sheets the following columns;
Client, Job Number, Project Name, Details, Date, Day, Start Time, End Time, Duration, If it's Fixed Price, If its an Hourly Rate, What the hourly rate is, Total Hours, Price, Discount %, Final Price.
Within these Columns I need to be able to filter by date, by client or by job number - so I can easily check what hours Ive done on a particular job, or on a given day how many hours I've done or how many jobs I've done for a particular client.
As a result I will formulas on the timesheet the number of hours and minutes (down to ten minutes) for the duration, to calculate the price from the hourly rate, then the price after the discount and the final price.
However, some jobs may be a fixed price, and I may work on it for more than one day, Some Jobs may be an hourly price. So, if I put in the coloumn the fixed price each time/day I register time worked on it. It needs to see that that fixed price is for the job, not for that days work.
I would also like to be able to do a forecast sheet, so I can enter estimate details in, to see what I'm forecast to earn.
I would also then need a sheet which pulls in the info from the forecast to show the projected time taken earnings and also pulls in the information from the timesheet to show actual time taken and cost.
Is there any whizz out there that can help me on my way cos it has myself and my friend stumped and time is passing where I need to record my hours.

Hi iconboyip,
This will get you started.
E is formatted with as Date & Time, with no time displayed (by default, it will be midnight at the start of the day).
F and G are formatted as Date & Time with no date displayed.
Enter times with am or pm (or 24 hour clock) on the day you actually start and end. Otherwise, we have the "crossing midnight" problem feature .
H and I are formatted as Duration.
Enter breaks as 1h or 15m or 0.25h

Setting agent's default state to Ready in CAD

Hi,
We are using UCCX 7.0 with CAD 6.0. Is it possible to set the default state of the agent to Ready when they login to their CAD.Right now, they go to the default Not Ready state one they login.
Thanks,
DM

Hi
By design CAD agent initial state after login is always not ready and there is no specific setting in uccx were you can change this behanviour.
However you can check this post were they suggest to create a MACRO

DNS HA agent bugs?

I'm running SC3.2 on Sol 10 11/06 (fully patched). I'm using the DNS and DHCP agents side-by-side for my (test) cluster.
Failing the resource group between nodes works fine, without affecting DNS resolution or DDNS updates from DHCP. However, I have noticed a couple of problems with the agent.
All of my DNS config data lives in /var/named. If I create the resource group by running "clresource create -g dns-rg -t SUNW.dns -p Port_list=53/udp -p DNS_mode=conf -p Confdir_list=/var dns-res", I get an error:
# clresource create -g dns-rg -t SUNW.dns -p Port_list=53/udp -p DNS_mode=conf -p Confdir_list=/var dns-res
clresource: whelk - File /var/named.conf is not readable: No such file or directory.
clresource: whelk - Failed to validate configuration.
If I change "-p Confdir_list" to "/var/named", I still get an error:
# clresource create -g dns-rg -t SUNW.dns -p Port_list=53/udp -p DNS_mode=conf -p Confdir_list=/var/named dns-res
clresource: whelk - DNS database directory /var/named/named is not readable: No such file or directory
clresource: whelk - Failed to validate configuration.
If I create a link to named.conf called named in /var/named, the above command works properly. Is this a bug with the agent, or a requirement that something called 'named' must exist in the specified directory? Why did the first command error with "couldn't find /var/named.conf" and the second with "/var/named/named"? When BIND is running, I see:
/usr/sbin/in.named -c /var/named/named.conf
The second problem I have is with running BIND as a different user ie. named. This was easy to achieve within the SMF manifest, and if I was running BIND from the command line I would use "-u named" as an option. How can I achieve the same functionality with the DNS HA agent?

It is not clear to me if you use a failover filesystem for your dns configuration?
If you do, then you need to setup a resource dependency to the HAStoragePlus resource by listing "-p Resource_Dependencies=hasp-rs". Note that is one difference that Maddy used and you didn't (using old-cli or new-cli style does not make a difference otherwise).
Specificly the message
"clresource: whelk - File /var/named.conf is not readable: No such file or directory."
is only output in the szenario that /var/named.conf is not found on all nodes where the dns-rg can be hosted and if no HASP resource dependency is provided. If one is provided, then it is expected that this HASP resource must be online and validation happens only on the node where it is online.
If you do not use one, than you need either a global filesystem, or you need to make sure that all needed files are on all nodes.
So in order to understand the clrs error message, you need to check the syslog messages of all nodes to see on which node validation has failed and why.
Also note that using Confdir_list=/var is propapbly not a good idea, since the structure is that in your setup the agent expects ${Confdir_list}/named.conf as well as ${Confdir_list}/named/ which contains all of the DNS database files (listed in the named.conf file). And making /var either a global or failover filesystem is not really a good idea. Maintaining the config files an all nodes might also not be desireable.
The documentation is using a global filesystem (thus not showing the HASP dependency).
You can check http://docs.sun.com/app/docs/doc/819-2977/6n57s95iv?a=view
to see that the named directory is fixed.
Hope this helps.

Dhcp from linksys to catalyst Model number: WS-C2950G-24-EI

Should a linksys 4 switch port wireless router be able to DHCP a private IP address to a catalyst 2950 switch?

Does that mean this only applies to the non-mgmt interfaces?
Understanding DHCP-Based Autoconfiguration
The DHCP provides configuration information to internet hosts and internetworking devices. This
protocol consists of two components: one for delivering configuration parameters from a DHCP server
to a device and one for allocating network addresses to devices. DHCP is built on a client-server model,
where designated DHCP servers allocate network addresses and deliver configuration parameters to
dynamically configured devices.
With DHCP-based autoconfiguration, your switch (DHCP client) can be automatically configured at
startup with IP address information and a configuration file that it receives during DHCP-based
autoconfiguration. No DHCP client-side configuration is required on your switch.
However, you need to configure the DHCP server for various lease options. You might also need to
configure a TFTP server, a Domain Name System (DNS) server, and possibly a relay device if the servers
are on a different LAN than your switch. A relay device forwards broadcast traffic between two directly
connected LANs. A router does not forward broadcast packets, but it forwards packets based on the
destination IP address in the received packet. DHCP-based autoconfiguration replaces the BOOTP client
functionality on your switch.
DHCP Client Request Process
When you boot your switch, the DHCP client can be invoked and automatically request configuration
information from a DHCP server under these conditions:
? The configuration file is not present on the switch.
? The configuration file is present, but the IP address is not specified in it.
? The configuration file is present, the IP address is not specified in it, and the service config global
configuration command is included. This command enables the autoloading of a configuration file
from a network server.

Interest in helping get a NetDirector PKGBUILD for Archlinux?

Hi,
I am the project lead for NetDirector, a free and open source (right now we use a modified MPL with attribution - we're moving either to GPLv3 or CPAL) system admiistration tool primarily for servers - www.netdirector.org
NetDirector is focused on managing at the service level - so, it provides robust (one-to-many changes, change scheduling, rollback, etc) and secure (strict role-based authorization and authentication, system communication encrypted in ssl,...) management for many of the most popular Linux server apps like Apache, Samba, DHCP, BIND, Sendmail, FTP, LDAP. We have a modular architecture, so additional services can be snapped in to NetDirector as plugins. Things others have expressed interest in are a plugin for Asterisk, ClamAV, Snort, quotas, MySQL and so on. Also, we have a plugin to Red Hat Network that extends NetDirector's role-based access control, one-to-many actions, scheduling and rollback to patching and provisioning done with RHN. Something like this to Pacman would be cool!!
I got turned on to Archlinux by a user.
I would love to see if anyone out here would like to help us get NetDirector packaged up and available through the Archlinux content repos.
Also, there are a variety of other things we could use some developer help on, too. If you want to get involved and know Java, please let me know.
Thanks in advance!
Greg

Hi guys,
thanks for rolling up your sleeves on this.
to get a sense of the NetDirector architecture, check out this page: http://www.netdirector.org/index.php?op … &Itemid=49
I hope it will help in terms of understanding the build process. Since NetDirector is a client/server tool, you need one server manager and one server agent installed on each server that you use netdirector to manage. Server Manager is by far the more complicated of the two pieces. Written in Java, it contains a database (mysql or postgresql), tomcat, the netdirector change management engine, the agent listener and more. The Server Agent is simple by contrast - written in Python, we designed the Agents to be pretty dumb so as not to gobble up toomany resources.
I've asked my more technical partner to also reply to this forum in order to give you guys guidance
Blind and Tardo - do you thihnk we should see how we make out here before I put this request to the mailing list?
Thanks
Greg

Issues with ODI connection to Hyperion Financial Management

Hi,
I am having some issues with ODI connection to Hyperion Financial Management. ODI and Financial management are setup on different machines.
The ‘Cluster(Data Server)’ name in Topology is given as ‘hfm03cl’. On reverse-engineering a model it gives the following error:
org.apache.bsf.BSFException: exception from Jython:
Traceback (innermost last):
File "<string>", line 38, in ?
com.hyperion.odi.common.ODIHAppException: Error occurred in driver while connecting to Financial Management application [HFM1] on [hfm03cl] using user-name [admin].
at com.hyperion.odi.hfm.ODIHFMAppConnection.<init>(ODIHFMAppConnection.java:58)
When HFM is installed on the same machine, it works fine. How does ODI identify a cluster on a different machine? Do I have to give the machine name along with the cluster name? If so, what is the format?
Thanks,
Su

You will need to have the HFM client installed on any machine that will be running ODI (i.e. Designer or Agent) that will be executing connections to an HFM server.
Once you have the HFM client installed, see if you can actually connect to HFM from that machine using the HFM client.
Couple of other thing, in the Physical Schema, have you set the Application Catalog and Work Catalog to the same HFM application?
Also, when you are reversing, are you using the local agent or one you have installed using agentservice?
