• iPhone: Get value in multi-dimentional array

  - by Nic Hubbard

  I have an array that is many levels deep and I am wondering what is the best way to get one of the child element values that is deep in my array. I assume I need to use a recursive method, but what is the best way to do this? Or is there a faster way to do this? The array comes from an XML Parser that I am using which builds everything into an array like this (using NSLog to show the structure): { children = ( { children = ( { children = ( { children = ( ); data = 12; element = AssetID; } ); data = ""; element = "ns1:GetUserIdByUsernameResponse"; } ); data = ""; element = "SOAP-ENV:Body"; } ); data = ""; element = "SOAP-ENV:Envelope"; } What I would like to get at is the AssetID data, which in this case is 12.

• iPhone SDK: Adding Input Field Group

  - by Nic Hubbard

  I cannot find how to a text field group, similar to what is in the Address Book app: Can someone tell me what I am doing wrong? I can't find an option to make them look this way. Also, does anyone know the font, font size and color?

• Using an ActiveX object from an Outlook hosted webpage - possible?

  - by Nic Wise

  I'm trying to do the following: We have an outlook plugin, written in .NET (and C++). It does various things, and is manually installed on the end users machines (usually via AD deployment or similar) We are changing our search to use a webpage-based search, but from within outlook. That part is ok, however we want to communicate from the webpage to the surrounding outlook application. We can call into outlook by exposing an ActiveX object from our plugin, however we get security warnings, even if it's signed and marked as safe for scripting. Is this even possible? Has anyone done it? Anyone have a better way of doing it? We only need to pass in a small amount of data (a message id), and only from the webpage to outlook [update]: This is the error: automation server can't create object. We can get around it a bit by turning things off in IE, but thats not a good way to do it! Thanks

• PHP: Return string between two characters

  - by Nic Hubbard

  I am wanting to use "keywords" within a large string. These keywords start and end using *my_keyword* and are user defined. How, within a large string, can I search and find what is between the two * characters and return each instance? The reason it might change it, that parts of the keywords can be user defined, such as *page_date_Y* which might show the year in which the page was created. So, again, I just need to do a search and return what is between those * characters. Is this possible, or is there a better way of doing this if I don't know the "keyword" length or what i might be?

• Creating a dynamic lacp trunk from HP Procurve 2412zl to Proliant DL380 G7

  - by Maalobs

  I'm configuring an IEEE 802.3ad (LACP) dynamic trunk from a HP Procurve 2412zl (firmware version K.15.07) switch to a HP Proliant DL380 G7 server. The DL380 has 4 NICs and is running Win2008 R2, so I'm teaming the NICs together and leaving everything on the recommended "automatic" setting in the HP NIC configuration tool. The server is one of two, they'll be connected on interfaces F17-F20 and F21-F24 respectively on the switch. I need the servers in a separate VLAN, here is the configuration for the VLAN: vlan 10 name "Lab_Mgmt" untagged B2,F17-F24 ip address 172.22.71.3 255.255.255.0 tagged B21 exit There is a DHCP-relay into the VLAN 10 from another device beyond interface B21. The Advanced Traffic Management Guide says that in order to run a dynamic LACP trunk on another VLAN besides the DEFAULT_VLAN, you need to first enable GVRP and then use "forbid" to stop the interfaces from automatically joining DEFAULT_VLAN when the dynamic trunk is created. GVRP brings some other stuff with it that I don't want or need, so I disable it with "unknown-vlans disable" on all other interfaces. Here is how I do it: procurve-5412zl-1(config)# gvrp procurve-5412zl-1(config)# interface A1-A24,B1-B24,C1-C24,D1-D10,D13-D24,E1-E24, F1-F16,K1,K2 unknown-vlans disable procurve-5412zl-1(config)# vlan 1 forbid F17-F24 procurve-5412zl-1(config)# interface F17-F20 lacp active The result afterwards looks all successful: procurve-5412zl-1(config)# show trunks Load Balancing Method: L3-based (Default), L2-based if non-IP traffic Port | Name Type | Group Type ---- + -------------------------------- --------- + ------ -------- F17 | XYZTEAM3_NIC1 100/1000T | Dyn2 LACP F18 | XYZTEAM3_NIC2 100/1000T | Dyn2 LACP F19 | XYZTEAM3_NIC3 100/1000T | Dyn2 LACP F20 | XYZTEAM3_NIC4 100/1000T | Dyn2 LACP procurve-5412zl-1(config)# vlan 10 procurve-5412zl-1(vlan-10)# show lacp LACP LACP Trunk Port LACP Admin Oper Port Enabled Group Status Partner Status Key Key ---- ------- ------- ------- ------- ------- ------ ------ F17 Active Dyn2 Up Yes Success 0 0 F18 Active Dyn2 Up Yes Success 0 0 F19 Active Dyn2 Up Yes Success 0 0 F20 Active Dyn2 Up Yes Success 0 0 On the Proliant server, the NIC configuration Tool is also indicating that a 802.3ad dynamic trunk has been established. Everything should be good, but it isn't. The server is not getting an IP-address from the DHCP, which it does if I'm not enabling LACP. If I configure the server to a static IP-address on the VLAN 10 subnet, it can't even ping the switch IP-address, much less anything outside of the VLAN. The switch can't ping the server either. I did another attempt with F17-F20 tagged, and checking the box "Default Native Tag (VLAN 10)" in the NIC configuration tool on the server, but there was no difference. Does anyone have any idea what I might have missed?

• Problems with 2 ISCSI connections esxi 3.5

  - by rphilli5

  I am running a dell poweredge 1950 with 4 nic cards. 1 is bonded to SAN #1 on 192.168.90.xx. The second SAN is on a separate network - 192.168.7.xx The network adapter can view the ip range of the san and the NIC can be pinged from 192.168.7.xx range. vswitch1 and vswitch2 are configured identically except for the ip address. The second SAN has been added to the iscsi software adapter but the SAN is never recognized. I can connect to the SAN from other machines on the local network. Is there something else that needs to be configured for the iscsi software adapter to know which vswitch to use?

• RRAS VPN Server on Windows 2008 Behind NAT

  - by Chris

  Ok, so I have kind of a funky setup, let me see if I can describe it. I have a single VMware host with a public IP address 74.xx.xx.x Inside that host, I have 3 VM's Web Server - 1 NIC - 192.168.199.20 SQL Server - 1 NIC - 192.168.199.30 RRAS/VPN Server - 2 NICs 192.168.199.40 & 192.168.199.45 Due to Limitations of my ISP, all of the VM's are connected to the host VIA NAT. I have NAT setup for the webserver so all incoming requests on 74.xx.xx.x via port 80 route to 192.168.199.20. This works fine. Now I want to set up a Windows 2008 VPN server inside this NAT network and forward the correct traffic to it. My questions are as follows? What are the TCP/UDP ports that i have to forward? What special configuration is needed on the server and clients since this is behind a NAT Any other advice would be wonderful.

• Migrating 2008 AD to Windows SBS 2011 and Forefront TMG 2010

  - by Tong Wang

  Our company has two physical servers: a Dell R710 with 4 NIC and a Dell R410 with 2 NIC. Right now, we have Windows server 2008 R2 installed on R710 with AD setup to host our domain. I am thinking to install both SBS 2011 and TMG 2010 on the other R410 running on Hyper-V. As I am fairly new to Windows Server technology, I'd like to check with you fellow Windows admins and see what is the proper way to install SBS 2011 and TMG 2010 and how to migrate the 2008 AD. Your advice and help will be highly appreciated.

• Is bonding mode=5 a solution against MAC flapping?

  - by Yuri

  There is two are interconnected Cisco WS-2950T. By the one GBIC port on first switch connected a first NIC of bonding interface, and by the one GBIC port on second switch connected a second NIC of bonding interface. Of course the both switches sees the bonding MAC-address only on one interface (eg it is GBIC on first switch) and all incoming traffic for bonding interface passes through this GBIC. But in "mode=5" all outgoing traffic are distributed between the all interfaces that make bond. In this case, the packets will be dropped from the second switch and anyway will going through the first switch? Or the division will be working?

• NLB 2 Windows Server 2003 Servers

  - by Paul Hinett

  I need to configure windows NLB on 2 dedicated servers I have. My main machine has been running for some time, with several domain names pointing to the servers primary IP address. Both servers have 2 NIC's installed, and both have several secondary public IP addresses available if needed? What IP address would I use for the cluster IP, does this IP need to be added to the IP list of both public NIC's ip address list? What IP addresses do I use for the host's dedicated IP? Please help, this is driving me nuts...i've taken down the server twice on accident today! Thank you in advance!

• How can I tell which interface my Supemicro IPMI is piggybacking on?

  - by lorin

  I've used IPMI before, but only on servers where the IPMI interface had a dedicated ethernet port. I've got an Ubuntu 10.04 server with two ethernet cards, which is supposed to have an IPMI interface on it (the motherboard is a Supermicro H8DMR-I2). From what I understand, the IPMI interface is piggybacking on one of the two NICs. Is there any way I can tell which NIC the IPMI interface is piggybacking on? Using ipmitool I've tried to set the IP address on the IPMI interface for the subnet for eth0, and then the subnet for eth1, and it's never reachable. (Can you even reach an IPMI interface from the same NIC it's piggybacking off of, or do you need to try connecting from a different machine on the network?) Also, is there anything special I need to do to enable it? I can access the IPMI interface locally using "ipmitool".

• Would firewire networking be better than 100Megabit ethernet?

  - by Josh

  My office network has a fully switched 1000Megabit ethernet network. I have an Apple iMac with a Gigabit NIC and FireWire, and a Compaq laptop with a 100Megabit NIC and a 4-pin FireWire interface. Accessing my office's shared drives using my laptop is (obviously) much loswer using my laptop than my iMac. Would I see a noticeible performance boost if I enabled Internet Connection Sharing on my iMac and shared the private ethernet network from my iMac with my laptop over FireWire? FireWire is 480Mbit/sec, right? So would I see roughly 4x speed improvement with such a setup?

• dell poweredge 860 always pxe boot

  - by Berto

  Hi, We bought a dell poweredge 860, and installed windows server 2008 std. So far so good. Now everytime the server reboots, it try's the pxe boot, and hangs on "cant find pxe bootable, press f1 to continue or f2 to setup". Now, i tried all the settings in the bios (it's the latest - A05), i have the nic active without pxe (i also tried with the nic off)... well, i tried everyting off and on the bios and it still goes to pxe booting. I have one sata drive, that is boot's after the f1. I would like to keep the system updated, but i can't because of the reboot, can someone point me to some direction? Can i give any more information of the server? If yes, what do you want? It has been a week on google trying to figure out this one. Thx

• ESXi and Networking Devices

  - by EsxiUser

  I have two intel pro 1000 pt nics. One quad and one dual port. I want to assign all nic ports to a VM. I enabled PCI passthrough on all devices but ESXi will only allow me to add two nic ports until it tells me the maximum number of pci devices have been added. I have also tried setting up a virtual switch but it didn't seem like this would give full access to the nics. What is the best way to setup the nics to the VM has direct access to them? This is for a firewall VM.

• Windows Server 2008 - one MAC Address, assign multiple external IP's to VirtualBoxes running as guests on host

  - by Sise

  Couldn't find any help @ google or here. The scenario: Windows Server 2008 Std x64 on i7-975, 12 GB RAM. The server is running in a data centre. One hardware NIC - RealTek PCIe GBE - one MAC Address. The data centre provides us 4 static external IP's. The first is assigned to the host by default of course. I have ordered all 4 IP's, the data centre can assign the available IP's to the physical MAC address of the given NIC only. This means one NIC, one MAC Address, 4 IP's. Everything works fine so far. Now, what I would like to have: Installed VirtualBox with 1-3 guests running, each gets it's own external IP assigned. Each of it should be an standalone Win Server 2008. It looks like the easiest way would be to put the guests into an virtual subnet and routing all data coming to the 2nd till 4th external IP through to this guests using there subnet IP's. I have been through the VirtualBox User Manuel regarding networking. What's not working: I can't use bridged networking without anything else, because the IP's are assigned to the one MAC address only. I can't use NAT networking because it does not allow access from outside or the host to the guest. I do not wanna use port forwarding. Host-only networking itself would not allow internet access, by sharing the default internet connection of the host, internet is granted from the guest to the outside but not from outside or the host to the guest. InternalNetworking is not really an option here. What I have tried is to create an additional MS Loopback adapter for a routed subnet, where the Vbox guests are in, now the idea was to NAT the internet connection to the loopback 'subnet'. But I can't ping the gateway from the guests. By using route command in the command shell or RRAS (static route, NAT) I didn't get there as well. Solutions like the following do work for the one way, but not for the way back: For your situation, it might be best to use the Host-Only adapter for ICS. Go to the preferences of VB itself and select network. There you can change the configuration for the interface. Set the IP address to 192.168.0.1, netmask 255.255.255.0. Disable the DHCP server if it isn't already and that's it. Now the Guest should get an IP from Windows itself and be able to get onto the internet, while you can also access the Host. Slowly I'm pretty stucked with this topic. There is a possibility I've just overlooked something or just didn't getting it by trying, especially using RRAS, but it's kinda hard to find useful howto's or something in the web. Thanks in advance! Best regards, Simon

• Fedora12, XP and connection sharing via iptables

  - by Paul L

  Just a quick question ( I Hope ) To find out if what I'm trying is even possible. I am trying to share internet connection with Fedora12 as default gateway and XP machine hooked up via NIC using iptables commands as shown in Mark Sobell's book 'A Practical Guide To Fedora And Red Hat Enterprise Linux' These are the commands as placed in /etc/rc.local iptables -A FORWARD -i eth1 -o eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A FORWARD -i eth0 -o eth1 -j ACCEPT iptables -A FORWARD -j LOG iptables -t NAT -A POSTROUTING -o eth1 -j MASQUERADE I did flip the in and out parameters to match my NIC configuration ( as opposed to example from book ) but other than that followed example. One thing to note is that Sobell did not mention whether this should work with mix of Linux and XP. One other note ( maybe meaningless ) is that I do have samba working between the two machines. Thanks for any insights anyone might have. PL

• How to separate Hyper-V Private network from the External network

  - by Ron Ratzlaff

  I am setting up a virtual test lab and I configured a domain controller VM running Windows 2008 R2 on my Hyper-V 2008 R2 server. I needed to download and install updates on it so I added an External NIC adapter and got that done. However, systems on my actual real physical domain were pulling IPs from this server and that was a big oopsy on my part so I immediately removed the External NIC adapter until I could find out how to go about keeping the Private and the External separate. If someone from the Server Fault community can help with this since I am pretty new to this, I would be very grateful. Thanks everyone.

• Sizing a Virtual Server

  - by vdubs

  I would like to replace four aging physical servers with one virtual server. What is the best way to insure the VM server is sized correctly? The requirements of the apps that will be running on the four servers are APPLICATION SERVERS - QTY 3 - These will run the application layer for the web server, Business Objects Business Intelligence app, and various other small client server apps. The three most heavy hitting apps each have the following server requirements. So, if I bought three physical servers, this would be the requirements for each of them Processor - Dual 2.83 GHZ (or faster) Ram - 4 GB Raid 5 - 50-100GB usable space NIC - 1 GB Web Server - this will run one asp.net e-business app that will talk to our dedicated SQL server and the three app servers above. The E-Business software has these requirements for the web server Processor - Quad 2.83 GHZ (or faster) Ram - 8 GB Raid 5 - 50-100GB usable space NIC - 1 GB What is the best tool to determine what I need from a hardware standpoing in a virtual server? I am planning on using VMWare.

• Static Routes and the Routing Table

  - by TheD

  This is very much a learning question if someone would be happy to explain a couple of concepts. My question is - the default routing table that exists in, in my case, a default Windows 7 install, what do each of the routes in the table do? Here is a screenshot: The 10.128.4.0 is just a route I've added while messing. I understand from a question I posted on Superuser the first route is just a default route that will route all traffic for any IP to my default gateway on my Interface in use. But what about the others? And how would the routing table handle a machine with multiple NIC's, perhaps connected to two different networks, or maybe even two NIC's on the same network so a VM can have a physical Network card instead of each VM sharing the hosts. Thanks!

• Problem with Jumbo Frames

  - by Spookyone

  Hello, I am trying to set up jumbo frames on my gigabit home LAN but no luck so far. My setup is: * D-Link DIR-655 router, HW Revision A3, Firmware 1.21 EU * Synology DS107+, Firmware 3.0-1337 * Laptop w/ Win7 x64, external PCIx NIC managed by "Generic Marvel Yukon 88E8053 based Ethernet Controller" The router is supposed to support jumbo frames but doesn't feature any relevant setting. I set the Jumbo Packet value to 9000 on both the NIC and the Synobox but it doesn't work, ping -f -l 8972 says "Packet needs to be fragmented but DF set". Is there any other setting I overlooked, the DIR-655 doesn't actually support jumbo frames, or what else could be the problem?
