• Configuring HAProxy with memcache with failover

  - by Lawrie Matthews

  I'm configuring a new set of servers for an existing Wordpress site, and it's been requested that memcache be available and made more resilient. The idea proposed is to have HAProxy send requests to one of the two servers; if that memcache instance is inaccessible, then it should switch to the second, but should not switch back to the first if it comes back up unless the second is then unavailable. This doesn't appear to be a particularly common use case and I've not found much along these lines except to possibly set up the first node with an enormous rise value, such as: server server1 10.112.58.16:11211 check inter 5s fall 3 rise 99999999 server server2 10.112.58.19:11211 check backup which falls over as expected when server1 is unavailable. It won't ever fall back to server1, though, even if server2 goes offline. Can this be made to work?

• Windows data backups with alternating removable drives?

  - by luke

  0 vote down star I have a removable disk drive (RD1000 from Dell), and I am looking for backup software that will allow me to backup every night, and every morning switch to the alternate disk. There is only one directory structure to back up, what I want is two copies, one which I will take home with me every night, one which will be backing up every night, and when I get in in the morning, I will switch them. So for instance I have disk "a" and disk "b". On Monday night I want to go home with disk "a" and leave disk "b" in the drive, so that a scheduled back up will be written to it. On Tuesday morning I will come in and swap disks, and I will take "b" home that night, leaving "a" for the backup. And so on for the remainder of the week. FOSS software preferred, Freeware acceptable, paid software as a last-ditch effort. Oh, btw I'm stuck with Windows 2000 Thanks in advance.

• Windows Server - Dual NIC Bandwidth Pooling

  - by tsilb

  I have a Windows Server 2008 machine with dual NICs. Both are plugged into the same switch in a typical one-switch, one-gateway home network. This server is used almost exclusively for inbound connections. It hosts a web server (IIS 6), SQL server, and file server (via LAN UNC paths and mapped drives). How do I make best use of inbound bandwidth across both NICs? For example, if I connect to it by hostname and one of the interfaces has high traffic, I'd like the new connection to use the other interface.

• Best security practice for small networks - wifi, lan,

  - by Grimlockz

  We regularly setup small networks for clients in different locations to allow them to work on different products now the question what should be the best security practice. Currently we have a wifi enabled with WPA2 and most laptops connect to this but some will connect to a cabled switch connecting to the router. We are thinking on what we should do to increase the security on our small networks - We do have have security on the laptops so you can share directly to the other persons drive by a simple Windows user account. Some suggestions are: We get a LAN switch with ACL control and mac filtering for the hard wired connections? We get acl working on the wifi via a good Cisco router? ipSec policies on all machines? IP filtering and fixed IPs? I suppose people are worried that anyone can plug into the switches and get the access to the network . Summary: Maintain a level of decent security that can be replicated easily to every setup that we do for clients

• Setting up D-link AP2100 as a repeater

  - by Mersan

  Hi, I have two D-Link AP2100, one is connected to a switch (with cable). The second one I would like to use as a repeater, using the WiFi connection to the first and not connected to the switch. Does anyone know first if this is possible, and second and most important, how does one do it. I have tested to set the second AP in repeater-mode, and it is connected to the first, I have full strength to the second one, but I'm not receiving any IP från the DHCP-server, so no access out. Any ideas? /Mersan

• AIX network parameters to close TCP sockets of unplugged devices

  - by ADD Geek

  Hi there We have an AIX box, running what we call in banking "ATM Switch" not the ATM networking switch, but the bank ATM driver. where we have some ATM machines connected to two server processes. The problem is, when we disconnect any of these machines, the netstat -na| grep <port number> command shows that the socket established for this disconnected device is still established, we have to manually send a command from the software to make the socket aware that it is not live anymore. Is there a parameter on tcp level to make this connection aware within a minute or two that this device is not connected anymore? we had the following parameters set with root privileges: no -o tcp_keepidle=1000 no -o tcp_keepcnt=2 no -o tcp_keepintvl=150 no -o tcp_finwait2=100 it was originally having the default values. but even after we changed these parameters and restarted the server processes, the problem was still there.

• How can I set the time that Windows 7 changes the background in the background slideshow?

  - by wes

  I've set up my Windows 7 background slideshow with a few choice wallpapers and set it to cycle daily, nothing excessive. Glad to see this feature built into Windows now. My problem is that the change happens at 3 in the afternoon, the time when I originally set up the background. I'd like it to switch at night, so I can come in to work each day to a fresh look. Is there a registry entry I can edit to manually set that switch time? Waiting until midnight to set it doesn't count :P

• My linux server takes more than an hour to boot. Suggestions?

  - by jamieb

  I am building a CentOS 5.4 system that boots off a compact flash card using a card reader that emulates an IDE drive. It literally takes about an hour to boot. The ultra-slow part occurs when Grub is loading the kernel. Once that's done, the rest of the boot process only takes about a minute to get to a login prompt. Does anyone have any suggestions? I suspect that it may have to do with UDMA. Everything IDE-related in my BIOS seems to checkout. The read performance hdparm is telling me 1.77 MB/s. Ouch! (But even at that rate, it still shouldn't take an hour to decompress and load the kernel) [root@server ~]# hdparm -tT /dev/hdc /dev/hdc: Timing cached reads: 2444 MB in 2.00 seconds = 1222.04 MB/sec Timing buffered disk reads: 6 MB in 3.39 seconds = 1.77 MB/sec Trying to enable DMA is a no-go though: [root@server ~]# hdparm -d1 /dev/hdc /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) Here's some command outputs that might help: System [root@server ~]# uname -a Linux server.localdomain 2.6.18-164.el5xen #1 SMP Thu Sep 3 04:47:32 EDT 2009 i686 i686 i386 GNU/Linux PCI info: [root@server ~]# lspci -v 00:00.0 Host bridge: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub (rev 02) Subsystem: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub Flags: bus master, fast devsel, latency 0 Capabilities: [e0] Vendor Specific Information 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller]) Subsystem: Intel Corporation 82945G/GZ Integrated Graphics Controller Flags: bus master, fast devsel, latency 0, IRQ 10 Memory at fdf00000 (32-bit, non-prefetchable) [size=512K] I/O ports at ff00 [size=8] Memory at d0000000 (32-bit, prefetchable) [size=256M] Memory at fdf80000 (32-bit, non-prefetchable) [size=256K] Capabilities: [90] Message Signalled Interrupts: 64bit- Queue=0/0 Enable- Capabilities: [d0] Power Management version 2 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 Flags: bus master, medium devsel, latency 0, IRQ 16 I/O ports at fe00 [size=32] 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 Flags: bus master, medium devsel, latency 0, IRQ 17 I/O ports at fd00 [size=32] 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 Flags: bus master, medium devsel, latency 0, IRQ 18 I/O ports at fc00 [size=32] 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 Flags: bus master, medium devsel, latency 0, IRQ 19 I/O ports at fb00 [size=32] 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 01) (prog-if 20 [EHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller Flags: bus master, medium devsel, latency 0, IRQ 16 Memory at fdfff000 (32-bit, non-prefetchable) [size=1K] Capabilities: [50] Power Management version 2 Capabilities: [58] Debug port 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) (prog-if 01 [Subtractive decode]) Flags: bus master, fast devsel, latency 0 Bus: primary=00, secondary=01, subordinate=01, sec-latency=32 I/O behind bridge: 0000d000-0000dfff Memory behind bridge: fde00000-fdefffff Prefetchable memory behind bridge: 00000000fdd00000-00000000fdd00000 Capabilities: [50] #0d [0000] 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) Subsystem: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge Flags: bus master, medium devsel, latency 0 Capabilities: [e0] Vendor Specific Information 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01) (prog-if 80 [Master]) Subsystem: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 17 I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at f800 [size=16] Capabilities: [70] Power Management version 2 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01) Subsystem: Intel Corporation 82801G (ICH7 Family) SMBus Controller Flags: medium devsel, IRQ 17 I/O ports at 0500 [size=32] 01:04.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

• Change Gnome panel profile according to number of displays

  - by ifischer

  I'm running Ubuntu 10.04 on a Laptop. I have a startup script which enables external displays, if they are connected. It runs at GDM startup, configured in /etc/gdm/Init/Default. When i'm running without external displays, Gnome should use 2 Panels. When i'm using 2 external displays, Gnome should add an additional Panel to the second display. But this should of course be removed again if i detach the external displays (and restart). Can i configure this use case by using Gnome Panel-profiles? I read that there is a startup option "--profile" for gnome-panel, but i don't know how and where i could switch the profile, especially because this has to be done after recognizing the number of displays. Or can i add a general Gnome profile and switch between those profiles somehow to achieve this behavior?

• XP Restart After Power Failure

  - by Jim

  Hello, I've almost got my power settings sorted and was hoping someone could help? If I'm running XP and the power is cut, when the power is restored my machine auto restarts (this is what I want!) However, if I shutdown my machine properly (from the start menu & without touching the PC power button!), then switch the power off at the socket, then switch the power back on, the PC does not automatically restart. It's like the bios(?) recieives a message saying "aha, genuine shutdown and not a power cut, therefore do not restart on power restore." I want my PC to restart everytime it sees power restored from the socket? Any way round this? Anyone seen this before? I've upgraded my bios. Thanks in advance, Jim

• Link aggregation with freebsd8 and a cicso 3550, what am i doing wrong?

  - by Flamewires

  Hey, I am trying to setup Link Aggrigation with LACP (well, anything that provides increased bandwidth and failover using my setup will work). I'm running FreeBSD 8.0 on 3 machines. M1 is running 2 10/100 ethernetcards setup for link aggrigation using lagg. for reference: ifconfig em0 up ifconfig tx0 up ifconfig create lagg0 ifconfig lagg0 laggproto lacp laggport tx0 laggport em0 192.168.1.16 netmask 255.255.255.0 I plugged them into ports 1 and 2 of a Cicso 3550. then ran: configure terminal interface range Fa0/1 - 2 switchport mode access switchport access vlan 1 channel-group 1 mode active (everythings in vlan 1) Now Im able to connect the other computers to other ports on the switch and failover works great, i can unplug cables in the middle of a transfer and the traffic gets rerouted. However, im not noticing any speed increase. My test setup: load balancing: i tried dst and src on the switch, neither seemed to give me a speed increase. I am SCPing 2 500 meg files from the lagg computer to other computers (one each) which are also running 10/100 full duplex cards. I get transfer speeds of about 11.2-11.4 Mbps to a single host, and about half that (5.9-6.2) Mbps when transferring to both at the same time. From what I understood with destination load balancing the router was suppose to balance traffic headed for 1 computer over 1 port and traffic headed for another over a diff(in this case) the other port. With destination-MAC address forwarding, when packets are forwarded to an EtherChannel, the packets are distributed across the ports in the channel based on the destination host MAC address of the incoming packet. Therefore, packets to the same destination are forwarded over the same port, and packets to a different destination are sent on a different port in the channel. For the 3550 series switch, when source-MAC address forwarding is used, load distribution based on the source and destination IP address is also enabled for routed IP traffic. All routed IP traffic chooses a port based on the source and destination IP address. Packets between two IP hosts always use the same port in the channel, and traffic between any other pair of hosts can use a different port in the channel. (Link) What am i doing wrong/what would i need to do to see a speed increase beyond what i could do with just a single card?

• How to proxy to different named databases on the same server using MySQL Proxy?

  - by cclark

  I would like to have two databases on my MySQL server: DEV_DB_A DEV_DB_B However, in order to keep everyone's scripts, Query Browser settings and anything else from changing when we switch from using on DB to another I'd like to have everyone connect to DEV_DB and then use something like MySQL Proxy running a lua script which knows the currently active DB is DEV_DB_A and routes queries to there. If we restore a fresh version of the DB to DEV_DB_B or make some changes (e.g. partition a table) we can easily switch to DEV_DB_B by changing one Lua script instead of updating references everywhere. I had hoped I might be able to symlink inside of the mysql data directory but that didn't work so it seems like MySQL Proxy is a reasonable approach. Being new to Lua and MySQL Proxy I'm wondering if anyone else has approached the problem this way and how it worked.

• Is span monitoring on Cisco ASA 5520 possible?

  - by Brent

  From what I have read, you can use the switchport monitor command on ASA 5505's to setup a Span port due to the back of the ASA actually being a switch. On my 5520, I do not see the switchport command listed when issuing a ? via the CLI. How do people monitor traffic on non-5505's? My goal is to connect our IDS/IPS device that is running is promiscuous mode to a Ethernet port on the 5520 to monitor WAN traffic. I do not want to have to pass the WAN traffic through a switch as it would require me to get two (for redundancy) STP/switchport capable switches.

• Hyper-V virtual machine unable to get IP address from DHCP server running on same physical box

  - by Bronumski

  We have a Windows server 2008 R2 with two network cards running AD, DHCP, DNS and Hyper-V The first nic is setup with a static IP address and DHCP, WDS, and DNS are bound to it. The second nic is configured in Hyper-V to be only used by Hyper-V and has been automatically configured so that only the virtual switch is enabled on the adapter. DHCP and DNS work fine for all physical machines on the network. It also works for Virtual Machines running on another physical box. Virtual machines that are bound to the virtual switch network adapter are unable to get a IP address. If the virtual machine is given a static IP address with correct subnet, gateway and dns everything works. Has anyone else got this working?

• Changing Firefox Tab Cycle Order

  - by Mark Roddy

  When you use Ctrl-Tab in Firefox, you move through tabs in the order that they are listed in the tab bar at the top of the window. I would prefer that when I use Ctrl-Tab the next tab that I switch to is the most resently used tab. That way if I have two tabs I am using frequently I can easily switch between them without having to manually modify the ordering of the tabs via drag/drop. This is a feature that Opera has which I find to be very productive. Does anyone know of a setting or plug-in that will accomplish this for me?

• Virtual NIC on VM couldn't ping externally after Vmotion

  - by ToreTrygg

  Today I vmotioned 5 MS SQL 2005 servers over to a new DRS Cluster. All SQL servers use the "Production_LAN" network and a single virtual NIC of type "VMXNET 3". The first 4 SQL VM (Windows 2003 Standard or Enterprise x32 bit) vmotioned over without a hitch. The last SQL VM I vmotioned (Windows 2003 Standard x64 bit R2) vmotioned over without error, but I upon completion, I could no longer ping the VM. I went into the VM and could not even ping the gateway, however I could ping the loopback. This SQL server is extremely busy in comparison with the previous 4 VM's. I restarted the server and it came back up with the virtual nic working just fine. The build of both servers (vmotioner and vmotionee) is ESX 4.0.0 175625 - So, pre-update 1. Should I suspect the network switch/VM for possibly not updating the mac table on the switch? Anybody else ever have this issue or know what may have caused it? Thank you!

• HP Envy 14, Ubuntu 10.10 and trouble with the graphics cards

  - by Carsten Gehling

  A few days ago I bought a HP Envy 14, containing 2 graphics card: An integrated Intel graphics card, and an ATI HD 5650. I've installed Ubuntu 10.10 32-bit on the machine. Most things work fine out of the box, but the graphics cards are giving me trouble. When booting, I get the message "failed to get i915 symbols, graphics turbo disabled". Then the screen blanks out during the remaining boot period. I am able to get the display working by changing to one of the consoles, then closing and opening the laptop's lid. It seems that Ubuntu gets confused about which card to use. I've read here: http://www.andreas-demmer.de/en/2010/07/18/testbericht-linux-auf-dem-hp-envy-14 that I should be able to turn off one the cards by echoing keywords into /sys/kernel/debug/vgaswitcheroo/switch, but that path is not available on my system. The BIOS does not have any methods to switch of the ATI card. Help anyone? /Carsten

• What is the keyboard shortcut to clear formatting on Office 2008 Mac?

  - by Laurent Bourgault-Roy

  I recently switched from a PC to a brand new Macbook Pro. I was happy to see that most of the keyboard shortcuts in Word 2008 where the same or almost the same than in Word 2007. However, there is one keyboard shortcut that I dearly miss : the clear formatting shortcut (ctrl + space on Windows). I know the feature exists since it's in the formatting bar, but I can't find the keyboard shorcut. I tried cmd + space but that is the system keyboard shortcut to switch the keyboard type. alt + space delete the text without deleting the formatting. ctrl + space doesn't seem to do anything. Does anyone know what the keyboard shortcut for the clear formatting command may be? I hope there's one because it's really painful to reach for the mouse everytime I put a title and I want to switch to a normal paragraph style...

• Linux Live CD cannot play video

  - by lamwaiman1988

  I want to switch from windows to linux, but before the switch I would like to try them out in the Live CD. I downloaded the iso and created a multiboot usb stick ( by YUMI Multiboot USB Creator ). I can boot into Ubuntu Desktop 12.04 64 bit LTS and Linux Mint 13 Mate 64 bit. I can access the hard drive from there and I tried some video with the default player comes with them ( e.g: GNOME Player and VLC Player ). The player opened but the video didn't play. However, I can play the same video in Puppy Linux. ( Puppy Linux doesn't has a choice over 32-bit or 64-bit ) Maybe my CPU didn't support 64 bit? Here is a snap from CPUZ: CPU: AMD Phenom II X3 710

• "Hostile" network in the company - please comment on a security setup

  - by TomTom

  I have a little specific problem here that I want (need) to solve in a satisfactory way. My company has multiple (IPv4) networks that are controlled by our router sitting in the middle. Typical smaller shop setup. There is now one additional network that has an IP Range OUTSIDE of our control, connected to the internet with another router OUTSIDE of our control. Call it a project network that is part of another companies network and combined via VPN they set up. This means: They control the router that is used for this network and They can reconfigure things so that they can access the machines in this network. The network is physically split on our end through some VLAN capable switches as it covers three locations. At one end there is the router the other company controls. I Need / want to give the machines used in this network access to my company network. In fact, it may be good to make them part of my active directory domain. The people working on those machines are part of my company. BUT - I need to do so without compromising the security of my company network from outside influence. Any sort of router integration using the externally controlled router is out by this idea So, my idea is this: We accept the IPv4 address space and network topology in this network is not under our control. We seek alternatives to integrate those machines into our company network. The 2 concepts I came up with are: Use some sort of VPN - have the machines log into VPN. Thanks to them using modern windows, this could be transparent DirectAccess. This essentially treats the other IP space not different than any restaurant network a laptop of the company goes in. Alternatively - establish IPv6 routing to this ethernet segment. But - and this is a trick - block all IPv6 packets in the switch before they hit the third party controlled router, so that even IF they turn on IPv6 on that thing (not used now, but they could do it) they would get not a single packet. The switch can nicely do that by pulling all IPv6 traffic coming to that port into a separate VLAN (based on ethernet protocol type). Anyone sees a problem with using he switch to isolate the outer from IPv6? Any security hole? It is sad we have to treat this network as hostile - would be a lot easier - but the support personnel there is of "known dubious quality" and the legal side is clear - we can not fulfill our obligations when we integrate them into our company while they are under a jurisdiction we don't have a say in.

  Hello, I am owning a small company and we have purchased a server to setup few server applications on it as well as other software. We would like to setup our network in following way Internet<-WindowsServer2003 as router<-Switch<-Office Computers Server has two nic interfaces and we have 24ports 1GB network switch connected to one nic and internet connection to another nic. Our ISP is Frontier and we have Fios 25/25. We get network cable out of ONT box directly connected to our server. There are no modems/routers. Setting up DHCP on windows 2003 is easy job but we would like to have the ability to port forward some ports from office computers. I have some knowledge in networking but not as much. How could I setup FHCP server on win2k3 with the ability to port forward some ports to office computers? Thank you for your time

Other than this annoyance I like the case and the fan that comes with it.
